Ten characteristics of LED light source
â—The lamp body is very small  LEDs are small, very fine chips packaged in transparent epoxy, so it is very small, very lightweight, saving a lot of material and space in production and application. Â
â— very low energy consumption Â
The working voltage of LED is generally only 2~3.6V, and the working current is only 0.02~0.03A. That is to say: it consumes less than 0.1W, and consumes more than 90% less energy than incandescent lamps of the same efficacy. Reduced by more than 70%. Therefore, only LED is a true energy-saving light source! Â
â—Sturdy and durable Â
The LED wafer is completely encapsulated in epoxy. The small epoxy resin particles are extremely difficult to break, and the entire lamp body has no loose parts; the inner wafer is extremely difficult to break, and there is little thermal effect which may volatilize and melt. These characteristics make the LED difficult to damage. Compared with ordinary light bulbs, fluorescent lamps and LEDs can be said to be solid and sturdy, and they are numerous and durable. Â
â—Long service life Â
Under the right current and voltage, the service life of LED can reach 100,000 hours, which means that the product life is more than 10 years in theory. It is the only longevity star in the field of lamps. Â
â—Safe low voltage Â
The LED uses a low-voltage DC power supply (which can rectify AC power to DC power). The supply voltage is between 6 and 24V, which varies from product to product. In short, it uses a DC power supply that is safer than a high-voltage power supply, making it ideal for homes and public spaces. Â
â— Wide range of applications Â
Due to its small size, each unit LED chip is 3~5mm square or round, so it is more suitable for preparing devices with complicated modeling process. For example, the manufacture of soft, flexible tubes, strips, and shaped lamps is currently only suitable for LEDs. Â
â—More colorful Â
The color of the previous lamps is very simple. To achieve the purpose of color, one is to paint or cover the colored surface on the surface of the lamp, and the other is to charge the lamp with inert gas, so the richness of color is limited. LED is digital control, the light-emitting chip can now emit a variety of colors, including red, green, blue three-color, it is with this three-color, through the system control, you can restore the colorful world of the world. Â
â— Less heat dissipation Â
LED is a more advanced cold light source. It does not radiate a lot of infrared rays and ultraviolet rays like incandescent lamps and fluorescent lamps. It is especially suitable for the illumination of valuables such as cultural relics, jewellery and high-end cosmetics. There is almost no current thermal effect like incandescent lamps, and it is not subject to thermal expansion and contraction. It will not make the bulb yellow, will not accelerate the aging of the lamp, and will not constitute a greenhouse effect on the surrounding environment. Â
â— Less environmental pollution Â
The protection of LEDs for the environment is mainly manifested in three aspects: Â
First, there is no danger of metallic mercury. LED lamps do not use high-hazard mercury like fluorescent lamps, and there is no public hazard such as mercury ions or phosphors during lamp manufacturing or after damage. Â
Secondly, the epoxy resin for manufacturing LED is an organic polymer compound, which has good physical and chemical properties after curing. It has high bonding strength to wafers and metals, is hard and flexible, and is stable to salt and alkali and most solvents, and is not easily damaged. It can be recycled and reused even after damage or aging, and will not pollute the environment. Â
Third, the particle layout of LED lamps and displays, the light produced is generally scattered, and rarely produces light pollution. Â
â—More cost savings Â
Compared with incandescent lamps, fluorescent lamps and LED lamps are priced higher. However, due to the extremely low energy consumption of LEDs, in the long run, a large amount of electricity costs can be saved, and the investment in lamp replacement can be saved, so that the comprehensive use cost is more cost-effective.
