Tell you how to choose the right lamp for decoration at home

In the decoration process, the importance of purchasing lamps is no less than any big piece of furniture.

1. Introduction of household electric light source products

Home electric light source products are mainly divided into the following six categories:

Incandescent lamp

The most complete range, the best color rendering, but the heat is large, the life is short, the light color is single, and the energy efficiency ratio is low. The place where it is still used now is the Yuba lamp for bathroom heating. Its electrical energy is converted into very high heat and is especially suitable for heating. Nowadays, the summer is hot and uncomfortable. Everyone joked that life is given by air conditioners. In Hangzhou, where there is no heating equipment, in addition to the warm air equipment, your life is also given by Yuba.

Halogen lamp

Also known as tungsten halogen bulbs and quartz bulbs, it is essentially an incandescent lamp that is infused with halogen elements. It has higher brightness, wider color temperature range and longer life than ordinary incandescent lamps. It is usually used in places where concentrated lighting is required, such as home atmosphere lights and cars. Lights, spotlights in the counter of the mall.

The owner of the halogen lamp at home is also paying attention to the use: the halogen lamp housing can not be stuck with fingerprints, oil stains, etc., otherwise it will reduce the service life. At the same time, it is necessary to ensure good heat dissipation and avoid rapid fluctuations in ambient temperature.

Fluorescent lamp

Also known as the fluorescent lamp, from the outside is a closed rod-shaped tube, which is generated by ultraviolet light generated by the electrochemical process to illuminate the phosphor on the wall of the tube, and coated with different phosphors to emit different colors of light. Its life is about 5000. - 10,000 hours. Fluorescent lamps have been widely used in large halls, offices, and home lighting in the past, but they are not very energy efficient, and some rental rooms may still be available.

Energy saving lamp

It is a widely used type of lamp, which can be turned on at the moment of pressing the switch, and does not illuminate like a fluorescent lamp. Because of its small size and energy-saving advantages, it was used by the state in the past. However, containing mercury, waste products cannot be recycled, and damage can pollute the environment and affect health. Here again, fluorescent lamps and energy-saving lamps contain heavy metal mercury, which can pollute the environment; waste lamps should not be thrown into household garbage. Also, be careful not to use it in a wet or heavy dust environment to avoid fire hazards caused by short circuits.

LED light

Usually refers to the LED lamp bead lamp, the industry name is LED, now because the energy efficiency ratio is increasing, the pollution is very small, the price is close to the people, gradually replacing the energy-saving lamp into thousands of households, the service life is about 30,000-80,000 hours, part The product can reach 100,000 hours. The example application of the light source products I want to talk about in the home decoration is mainly LED lights, and other types of lights are used together.

There is also a development type called LED filament lamp . It is a new product developed to break through the limitation of the illumination angle of the lamp-type LED lighting products mentioned above. However, due to the limitation of heat dissipation technology, the power cannot be made very large. At present, it cannot replace the LED lamp bead, and can only be used as a matching light source. Use, the life expectancy is about 3-5 million hours.

The above two LED products are the trend of home decoration lighting. According to the different needs of area, brightness and color temperature, they can be combined to achieve their ideal lighting effect.

2. Example application of household electric light source products

1. Selection of color temperature of light source

In all kinds of lighting products, everyone's intuitive feeling of light is what color is light. Some people like pure white, some people like yellowish, the color of this light is called "color temperature" in industry terms.

We can compare and understand, the orange light of the incandescent lamp, like the afterglow of the setting sun, seems to be warm, the color temperature range is about 2300-3300K (K is Kelvin, color temperature unit), also known as warm yellow light; In the past, the long straight fluorescent lamps in the home, as well as the lights commonly used in hospital wards, emit light that is very white and has a cold and cold feeling. The color temperature range is about 5500-6500K, also called cold white light.

Some energy-saving lamps or LED lights, the color of the light is slightly whiter than the orange color of the incandescent lamp. The color temperature range is about 3800-4700K, which is called warm white light; between the cool white light and the warm white light mentioned above, the color temperature range About 5000-5500K, usually called bright white light.

The color temperature reference range for home lighting is roughly divided into the following areas:

restaurant

Suitable for warm color light, color temperature 2500-4000K, adding color to the invisible; â–²

living room

The main lamp lighting can be warm white (4000-4700K) or bright white (5000-5500K), to achieve bright but not dazzling effect; ambient light should be warm yellow, 2500-3300K; spotlights and the like Decorative cold white light, with the main lamp to create a warm and cold transition; â–²

Adult bedroom

It is advisable to use warm yellow or warm white light to create a warm feeling on the bed; children's room and study room: warm white light should be used to protect eyesight, bright and soft; â–²

Kitchen, bathroom, balcony and yard

It should be bright white or cool white light (5000-6500K), bright and sharp, and the outline of things is obvious, which is convenient for taking objects. â–²

I have made a table for everyone here. You can use it as a reference when you choose the lamp in the future. â–²

2. Selection of light source power

The reference power of different types of lamps in different places is as follows, taking LED light source as an example:

Bedroom of about 15 square meters

Light-colored walls and light furniture, open shades, the total light source is about 15W;

Open-ended or covered lampshade, the total source of light does not exceed 25W;

a decorative lampshade with poor light transmission, the total light source does not exceed 35W;

In the case of dark walls and furniture, the corresponding increase in each case is 5W.

15-20 square meters living room

On the basis of the light reference in the bedroom, each of the above cases is increased by 10-15W, which can be used with the spotlights to create light and shadow of different color temperatures. As a complementary light source, the LED strips on the top of the ceiling are tailored to the length requirements.

Living room of 20 square meters or more

Suitable for distributed lighting, in addition to the central main light, other locations can be matched with point or line array to help the lighting source. In terms of three-dimensional layout, you can use jewelry LED light source, such as glass or crystal light column. For the convenience of temporary reading, a vertical fishing light or a hanging light can be placed at the corner of the sofa. How can the lighting be better with the indoor environment? With the integration, you must design in advance or communicate with the decoration designer.

Kitchen, bathroom and balcony

Because it is necessary to avoid soot and water vapor erosion, closed ceiling lamps are often used, and the light source is selected from fluorescent lamps or energy-saving lamps. Compared with current LED products, heat generation is small and safe to use. Ring or U-shaped fluorescent lamps using electronic ballasts are essentially energy-saving lamps, and there is no difference in energy efficiency ratio and service life from integrated energy-saving lamps. The power is generally 32W or 40W.

Console lighting under the cabinet

It is suitable for bipolar tubular T5 LED tube , which is energy-saving and efficient. It is also convenient to replace and operate. It is actually a substitute for bipolar tubular fluorescent lamp. It has the same appearance, but the internal circuit of the lamp holder is different. It is necessary to pay special attention to the use of LED light source to ensure good heat dissipation in the use environment, and serious heat accumulation will cause the LED wick to be damaged by excessive light decay and aging. Therefore, it is advisable to purchase low power.

3. Selection of light source model

During the renovation process, some owners did not know what kind of light source products should be installed in their selected lamps. For example, the lamp holder should be small but bought, and the in-line type is purchased as a screw-in type. It is embarrassing to face the owner of the lighting store and even the inability to understand each other. I have listed some of the main light source products and models that I want to match. Let's make a reference.

3. Home brand recommendation

First talk about the price range of different types of light sources, the price rises with the increase of power, most of them range from a dozen to tens of yuan, some high-quality boutique lamps need to be hundreds of yuan, the same power comparison, the price trend is fluorescent light ≤ energy saving Lamp ≈ LED filament lamp ≤ LED lamp bead lamp.

At present, the production areas of large-scale lamps mainly include Zhongshan, Foshan, Shunde, Zhejiang, Ningbo, Jiangsu, Changzhou, Kunshan, etc. The brands with stable quality are Philips, Osram, Foshan Lighting, Op, NVC, Sunshine, Sanxiong Aurora, etc. These are less of a problem with short-lived bulbs.

It is often difficult to judge the quality of a lamp from the appearance. Some miscellaneous brands are prone to problems, mainly in the leakage of energy-saving lamps, uneven phosphors, insufficient amount of electronic powder, low specification of rectifier components, and poor quality. The quality problems are mostly manifested in poor design of the drive board, poor anti-interference, and poor heat dissipation of the whole lamp, resulting in greatly shortened life. It is recommended to use well-known brands as the primary reference when purchasing light sources.

4. Selection of lighting shades

Chandelier lampshade

The lampshade of the chandelier has a matte and color optional. In general, in order to ensure the flooding effect, a colorless frosted lampshade is selected.

Shade opening up

[Advantages] The lampshade has a soft light effect. The light in the opening direction hits the ceiling to form a diffuse reflection, and the head does not feel the glare of the light. It is the best choice for the owner who likes to create an atmosphere with light.

[Disadvantages] The upward light is easy to collect dust and flying corpses, forming some shadows on the lampshade. If it is not cleaned up in time, it looks dirty and old. In addition, the brightness of the light will have a certain influence. In the industry where the light is brighter, a light source with a larger power is mainly installed to compensate for the brightness loss caused by the lamp cover.

Shade opening down

[Advantages] Most of the light directly hits the object below, it looks brighter, and the lampshade does not fall into dust or flying insects, which is convenient for cleaning.

[Disadvantages] The light is not soft enough, it may be a bit dazzling, you need to add a separate atmosphere to create soft light.

Airtight lampshade

Although the lampshade solves the problems of dust, flying insects and soft light, it requires a certain amount of heat dissipation. At present, the mainstream energy-saving lamps and LEDs are inevitably heated. The poor heat dissipation will shorten the service life of the products, especially the LED products, reaching the critical temperature. Rapid light decay and aging. Therefore, the light source of the sealed lampshade should be selected as the product with low power and low heat.

Cover crystal lamp

Many owners pursue bright and beautiful lighting effects, then choose crystal lamps, through the concave and convex shape of the lampshade, the light transmission angle is changed to make the light and shadow change. Different forms, light and shadow refraction is gorgeous, suitable for space with relatively high floor height and large area, generally used in the living room, the top of the stairwell. The installation of crystal chandeliers in houses with a height of 2.8 meters or less has limitations. It is necessary to choose a smaller crystal chandelier or a ceiling crystal lamp to avoid the feeling of depression from the upper space.

Hollow lampshade

The other is the addition of insect-proof nets, owners who like the light and shadow, can choose such products.

5. Tips and suggestions for family lighting and darkness

1 baby's room, try not to have light on the face while sleeping

Studies have shown that babies sleep in strong light and are prone to myopia during growth. Keep the dim light in the room when the baby is resting. You can add a 1W LED night light to the socket below the bed.

2 Children's room avoids excessive light

Excessively intense light for a long time may also stimulate premature development of children, inhibit melatonin formation, cause endocrine disorders, dark circles, and prone to acne.

3 patients with disease follow the doctor's advice

For people with photosensitive dermatitis, you should follow the doctor's advice for reasonable daylighting. People with sleep disorders are especially unsuitable for lighting with strong light. Properly reducing indoor brightness can help improve sleep. When configuring the fish tank water source, choose blue, red, pink, blue and purple light colors.

The power is evenly distributed to illuminate the plants with 1-3 W lamp beads or strips. It is recommended to choose bright white or cool white LED for the fish tank viewing light source, the power is about 5W. It is not recommended to use illumination light directly as the growth source of aquatic plants. Because cyanobacteria in water is the main problem leading to water spoilage and hypoxia, the spectrum of cyanobacteria photosynthesis is green. In order to inhibit the growth of cyanobacteria, the green light source should be filtered out.

4 study room reading light with LED light source is better

The lamp is an AC-DC drive, and the normal qualified product has no stroboscopic problem. It does not have a 50MHz low-frequency flicker like fluorescent and energy-saving lamps (except for some high-frequency lamps; the human eye does not feel the flicker is above 80MHz). Fluorescent and energy-saving lamps also emit ultraviolet light, which is not good for the eyes.

It should be noted that the original light of the LED light is blue light, but the blue light is irritating to the visual cells, and it is necessary to filter out a certain amount of blue light. When selecting the light source of the reading light, the light bulb outer casing should be selected as milk color or similar. The coated product has the function of filtering blue light. The colorless frosted glass has a relatively poor filtering effect and is generally not used as a bulb for LED lamps.

The color temperature of the reading lamp is most suitable for warm white. It is recommended to use a warm color covering lamp cover to block the light source directly to the book or screen, and also to filter out part of the blue light. The power of the light source depends on the light transmission effect of the lampshade and the brightness of the whole house. It will be fine and comfortable to read.

6. Smart lighting products

The intelligent lighting system mentioned here refers to products that integrate infrared sensing, sound control, and wireless control. For example, a bathroom of a certain type can be installed with a directional infrared sensor switch, and one person enters, automatically turns on the light, and automatically turns off after coming out. When multiple people enter and leave, as long as there are people inside, they will remain always bright. After all the personnel are out, the lights will be extinguished. The logic control of PLC is involved here. It is also simple to implement, but there is no extensive market scale yet. Chemical products.

Many owners installed low-power night lights in the living room, aisles, etc., and they did not hit the wall at night. In addition, the dial switch + infrared sensor mode can be used to meet similar lighting needs.

Take the long aisle of some units as an example, install a double-unit single-control dial switch (the A/B mark is used for dialing), dial A and the infrared sensor switch in series, and dial B to go in parallel with the front switch group. No lighting is required during the day, both dial switches are turned off. If continuous lighting is required, only B is turned on; if it is only for a short period of time, such as going to the kitchen to pour water in the evening, or going to the bathroom, only open A, sensor switch Work, so that you can achieve the effect of turning off the lights and turning off the lights without hands-on.

Other lighting methods controlled by sound, infrared, Bluetooth, WIFI, etc., require you to use your imagination, combined with the technology that can be realized now, the light is moving, and every day is satisfied.

7. Installation of finished lamps

Before the renovation, it is necessary to discuss the decoration of the whole house with the decoration designer. Every room in the whole place has passed the inspection and rationality of the design lighting. Finally, it is implemented on the drawings, and the electrician sets the route according to the designed drawings. During this time, I walked around with other neighbors and visited some sample houses. Many home improvement forums consulted onlookers. Sometimes other people's ideas and experiences are also suitable for their own decoration. Learn to learn and adapt.

After the rough water and electricity are well prepared, the wall and ceiling are finished, the floor and the cabinet are fixed, there is no obvious dusting operation, and the installation of the lamps can be carried out. Otherwise, it will be cleaned up after the construction is finished. Even if it is wrapped up, it will be an extra process, which is more troublesome. The house that is delivered in hardcover should consider the large-scale color and style of furniture, curtains, wallpaper, etc. when purchasing the lamps, and avoid the inconsistency between the selected lamps and other soft clothes. In summary, the installation of the luminaire should be installed after the hard installation is completed and before the other soft installations come into play.

Some lightweight luminaires can be directly screwed to the screw holes of the ceiling power cable. Note that the light luminaires generally do not exceed 2KG. For heavy ones, separate holes are required to be fixed with galvanized or stainless steel expansion bolts. All are hung on the cassette, so there will be hidden dangers of the lights falling down and hurting people.

At present, most of the finished lamps with remote control function are LED products. Some rectifier boxes are exposed with a soft wire of 10-20cm. This is the receiving antenna of the remote control signal. Do not completely hide it in the ceiling lamp holder during installation, it will shield the signal. Remote control is not possible. Some products will take into account the overall aesthetics of the luminaire, have concealed antenna mounting slots, or be directly integrated into the shade section, both remote control and overall coordination of the luminaire. Pay attention to the antenna position when purchasing a remote control luminaire, or consult the seller.

8. Fault diagnosis and overhaul of lamps

If the luminaire fails, the most intuitive is that it does not illuminate. Some are suddenly not lit during use, some are flashing abnormally, and then completely extinguished, and some are used normally before, and then turned on later.

If there is no professional tool, it is difficult to judge the fault point and the cause of the fault very accurately, especially for those who do not have an electrician foundation. Here are just a few examples of routine maintenance methods, and serious faults should be handled by a professional electrician.

Suddenly not in use →

The basic reason is that the luminaire is broken, or the control circuit is broken, or the illuminator itself is broken.

The light is flashing abnormally →

Then completely extinguished, it is definitely a malfunction of the lamp.

Before using it, it will not be bright after turning it back. →

It may be a malfunction of the luminaire or a switch failure.

If the entire luminaire is not lit →→

1 Try to toggle the switch several times

If it happens to be bright, it is very likely that there is a problem with the switch. Like a dual-control switch, try both sides. (I once encountered a situation where one of the dual-control switches was pressed by the backrest of the bed, stopped in the middle, and the circuits on both sides were not connected. At this time, no matter how the other switch is pressed, the lights are not bright. of.)

2 short two lines

If you observe that the appearance of the lamp is not abnormal, you can first remove the switch and short the two wires. The light is on, indicating that it is a switch problem. If it is not bright, it is a problem with the lamp or wiring. (★ Don't do this without electrician knowledge and hands-on ability, there is a risk of electric shock.)

If only a single lamp head is not lit →→

1 Try using the transposition method

Remove the unlit light and attach it to the lamp position of the lit lamp. It is possible to simply judge whether it is a problem of a light source or a problem of poor contact. There is also a case where the performance of the ballast of the energy-saving lamp or the driving plate of the LED lamp is unstable, and the time is good or bad. The test by the short-circuit method of the switch is also randomly lit or extinguished, which is a product aging problem or a quality problem.

2 A single energy-saving lamp does not illuminate. Generally, there are three cases:

1 After using for a long time, the electronic powder on the filament is exhausted, and it can be seen that there are black marks on the inner walls of the two ends of the lamp, and the lamp is completely scrapped.

2 The lamp glass loses its stress balance and leaks. This invisible problem is the most difficult to find and completely scrapped.

3 The components of the integrated electronic ballast are basically scrapped. Those who are familiar with the electronic circuit and understand the circuit of the energy-saving lamp can repair it. There are very few people who usually have it.

3 Single LED light is not lit, there are also three cases

1 poor heat dissipation, resulting in serious deterioration of the lamp bead light aging;

2 drive circuit components heat-resistant or impact-resistant failure, it is also necessary for professional people to repair,

3 The voltage fluctuates greatly, causing the driver or the lamp bead to burn.

Others are cases where the lamp cannot be lit or burnt due to a wiring error. These are all required to be repaired by a professional electrician. Those who do not have relevant knowledge and hands-on ability should not try to repair. After all, life safety is the most important, and there is a life!

Buy a light to go to a physical store or buy it online. Is it really cheaper on the Internet?

Generally speaking, the online purchase will be cheaper because he has excluded the cost of the venue and storage and has more room for profit. However, the quality of the products on the Internet is uneven, even if there are no brands, and the after-sales problem is difficult to be guaranteed. From my personal point of view, I still recommend that you go to the physical store to see the genuine purchase, of course, if you must buy online, you must first find out the qualifications of the other party to find out why he is cheap, do not be cheated.

Is there a difference between downlights and spotlights? I look at it almost.

The downlight is a kind of luminaire that is more concentrated than ordinary mounted luminaires. It is generally used for general lighting or auxiliary lighting. The spotlight is a kind of highly concentrated luminaire. Generally speaking, the same grade is more expensive. It should be noted that spotlights are generally not used for close-range illumination of wool fabrics, and there is also a flammable barrier at close range, which may cause fires.

Is the light strip necessary to install? what's the effect

A: The light strip is an ornament, not a must-have item. If you have a high demand for the quality of the decoration, you can try it out.

Encapsulated Transformer

Encapsulated transformers are low frequency which covered in a thicker coating of insulation than typical. Often the coils are completely encased in epoxy or an epoxy and aggregate mixture. Sometimes they are referred to as [potted" or [cast coil".

The encapsulated design is especially suited for installations in harsh environments where dust, lint, moisture and corrosive contaminants are present. Typical applications include: pulp and paper plants; steel mills; food processing plants; breweries; mines; marine and shipboard installations.

Epoxy resin encapsulated safety isolating transformer PE series

Model: PE4809C-M Power: 0.5VA

This kind of transformer is PCB welding mounting type. The input can be 110V, 220V, 230V, 380V. Output is customized. Both single way and double way are available.
