Lighting is the eyes of the home, a harmonious set of lights will make the home environment very beautiful. Now the height of the housing floor is generally very low, plus the ceiling, the height of the floor is generally only about 2.2 meters, the chandelier will appear to be depressed, and the thickness of the ceiling lamp is small, which is very suitable for the actual situation of the low floor of the domestic building, living room, bedroom, study, Restaurants, kitchens, balconies and other places are widely used, so ceiling lamps have become the mainstream choice for modern homes! Explain in detail below:
Ceiling lamp application
In the home, there are generally living room, master bedroom, guest bedroom, children's room, study, kitchen, dining room, bathroom, balcony, aisle, entrance and other spaces. Each space has its own unique functions and attributes, and the requirements for lighting are different. The matching of the lamps is also different. For example, the bedroom is pursuing warmth and comfort. Generally, it adopts a round ceiling lamp and a 24W power LED ceiling lamp, which is more suitable, and is equipped with a lamp strip, a spotlight and a bedside on the ceiling. Table lamps and various lamps are used together to meet the functions of rest and other functions.
Type of ceiling lamp
At present, LED ceiling lamps are available in three sizes: round, square and shaped. The circular shape mainly has four levels of 12W, 18W and 24W. 12W, caliber 230mm; 18W, caliber 300mm; 24W, caliber 350mm.
Square, size is large and small, power is 12W, 18W, 24W, 36W, 48W, 64W, 72W, etc., square ceiling lamps, generally used in the living room, because the living room requires enough atmosphere, and the square ceiling lamp is very suitable This atmosphere.
Structure of the ceiling lamp
The ceiling lamp is generally composed of a lampshade, a chassis, an aluminum substrate , a power source, and an LED light source.
Ceiling light structure
The lampshade is generally made of acrylic material or PVC material and is formed by blow molding. It has good light transmittance and uniformity, has good heat resistance and weather resistance, and the material does not crack and deteriorate. It can filter ultraviolet rays and look straight for a long time. No eye injury, no glare, no glare. I wrote a special manuscript to describe this, I am interested to see my circle!
The chassis, which plays a fixed role, carries the entire luminaire, generally using cold-rolled steel sheets, and then painted after stamping and forming! Durable, no discoloration, no yellowing, no paint, no rust.
The aluminum substrate, that is , the aluminum-based circuit board, bears the functions of welding the lamp bead, the circuit, and the heat dissipation, and is generally 1.2 mm thick;
LED light source is a light-emitting component. In the past, incandescent bulbs and circular fluorescent tubes were mainly used as the light source of ceiling lamps. LED light source is a new type of light source, which is 90% more energy-efficient than incandescent lamps and 50% more energy-efficient than fluorescent tubes. It saves electricity and money. And the life expectancy is up to 50,000 hours, far exceeding 1000 hours of incandescent lamps and 8,000 hours of fluorescent tubes. The core of LED light source lies in the chip. The most used one is the Sanan chip. The largest chip in China is the best value for money!
The power supply needs to convert the 220V mains into low-voltage DC. Therefore, the power supply is used. At present, the quality of the LED chip has been relatively stable. The power supply has become a key factor in the quality of the LED ceiling lamp. Many LED ceiling lamps are bad and the power supply is not good. Generally, a constant current power supply with an IC is required, and the lifetime is well guaranteed.
Installation diagram of ceiling lamp
As for the installation of ceiling lamps, there are also a lot of attention. It is estimated that many people will not install them after buying the lights online, so they can find relevant information from the Internet. The installation of ceiling lamps is more professional, involving the safety of electricity, and often requires a professional electrician to complete, so it is recommended to find the workers of the decoration company to complete.
The author takes a square ceiling lamp as an example, briefly describes how to install the ceiling lamp. The circular ceiling lamp is basically the same, but the lampshade is finally screwed up!
Installation instructions Retrofit of old ceiling lamps
The ceiling lamp has been born for 20 years. The previous ceiling light source used incandescent or fluorescent lamps. In recent years, LED light source technology has advanced by leaps and bounds, and LED ceiling lamps have been born. Compared with traditional ceiling lamps, LED ceiling lamps are more energy-efficient and light-emitting. The color is adjustable, the volume is lighter, and there is no infrared ultraviolet light, which is widely used to replace the traditional ceiling lamp.
Old-style ceiling lamps that have been used for a long time, although they can still be used, but the power consumption is too high, many people will choose to transform them into LEDs, mainly to change the LED light source retrofit board and power supply, the cost is relatively low, it is recommended to directly replace the new one because Now the price of LED ceiling lamps is not expensive, it is more than 70% cheaper than a few years ago!
