How about using LED lights?

LED lamps have advantages and disadvantages.

Advantages of LED lamp

It is the most ideal light source to replace the traditional light source and has a wide range of uses.

1, small size: LED is basically a very small chip, encapsulated in epoxy resin, so the LED lamp is very small and light.

2, low calorific value: LED adopts cold light technology, the calorific value is much lower than that of ordinary lighting.

3. Durable: LED is completely encapsulated in epoxy resin, and LED lamp is stronger than light bulb and fluorescent tube. There is no loose part in the lamp body, which makes the LED not easy to be damaged.

4, high energy saving: LED power consumption is quite low, generally speaking, the working voltage of LED is 2-3.6V. The working current is 0.02-0.03A, that is, the power consumption of LED lamp does not exceed 0.1w.. DC drive, ultra-low power consumption (single tube 0.03-0.06W), electro-optical power conversion close to 100%, the same light efficiency is more than 80% less than that of traditional light source.

5, long life: LED light source Some people call it longevity lamp, which means a lamp that will never go out. The solid-state cold light source is encapsulated by epoxy resin, and the lamp body has no loose parts, and there are no shortcomings such as easy burning, thermal deposition and light decay of the filament. The service life can reach 60,000-65,438+10,000 hours, which is more than 10 times longer than the traditional light source.

6. Variety: LED light source can use the principle of three primary colors of red, green and blue, and under the control of computer technology, make the three colors have 256 gray levels and mix them at will, which can produce 256× 256× 256 =16777216 colors, form a combination of different light colors, and realize colorful dynamic change effects and various images.

7. Environmental protection: environmental protection benefits are better. There are no ultraviolet rays and infrared rays in the spectrum, neither heating nor radiation, and the glare is small. In addition, waste can be recycled without pollution and mercury. The cold light source can be safely touched and belongs to a typical green lighting source.

8. High-tech: Compared with the monotonous luminous effect of traditional light sources, LED light source is a low-voltage microelectronic product, which successfully integrates computer technology, network communication technology, image processing technology and embedded control technology, so it is also a digital information product, a "high-tech" technology of semiconductor photoelectric devices, with the characteristics of online programming, unlimited upgrade and flexibility.

LED shortcomings

Expensive, need constant current drive, poor heat dissipation treatment is easy to light decay.

1, poor heat dissipation: this may be the biggest problem facing LED lamps at present. At present, the heat dissipation of LED lamps is very passive, and its main function is to lead out the heat generated by the combination of LED chips in LED lamps, and then conduct the heat out through the heat dissipation device, mainly by passive air cooling, so the heat dissipation design of LED lamps is very important, which is also the focus of scientific research investment of some LED lamp companies. However, the current LED cottage lights are often only formal and have no practical effect. Therefore, heat dissipation has become an important factor to judge the quality of lamps.

2, the weight is slightly heavier: when you buy a lot, you may find that many manufacturers pay more attention to promoting the heat dissipation materials of LED lamps. The publicity materials are nothing more than two key points, one is how the materials themselves are and the other is the weight. The weight of LED lamp is a big test for the lamp holder, because the previous energy-saving lamps have no heat dissipation device, so the weight is relatively light, and the weight of energy-saving lamps has little influence on the lamp holder, while LED lamps are different and have heat dissipation problems, so we should consider the influence of this weight on the lamp holder. At present, it is a dilemma for LED lamps to give consideration to heat dissipation and the weight of heat dissipation materials. The only thing we can do is to find a balance. Therefore, the weight can also be used as the selection standard of LED lights when purchasing. If the heat dissipation material is unqualified, its LED lamp will generally be lighter, but this is not a good standard. Therefore, it is recommended to buy LED lamps of more reliable brands.

3. The price is a little expensive: At present, the efficiency of energy-saving lamps is roughly at the level of 1W 1 yuan, while LED energy-saving lamps are basically at the level of 1W5~ 10 yuan. Fortunately, at present, the development of LED lamps is very rapid, and the cost is also decreasing. Coupled with subsidies from national policies, this shortcoming will be easily overcome one day.
