Advantages
Energy saving and environmental protection
The luminous principle of LED is different from that of incandescent lamp and gas electric-discharge lamp. The energy conversion efficiency of LED light source is very high, which theoretically can reach 10% energy consumption of incandescent lamp, compared with fluorescent lamps, LED can also achieve an energy saving effect of 50%. LED with a luminous efficiency of 75lm/W reduces the power consumption by about 80% compared with incandescent lamp with the same brightness, and has remarkable energy saving effect, which is undoubtedly of great significance to China, which is very energy-intensive. LED can also be combined with solar cells to save energy and protect the environment. It does not contain toxic and harmful substances (such as mercury), which avoids the secondary pollution of Mercury overflow due to the rupture of fluorescent tubes and does not interfere with radiation at the same time. The LED light source is not only more environmentally friendly and energy-saving, but also has wider color gamut and higher color saturation. More importantly, the service life of the LED lighting source is as long as 60000 hours, it can completely solve the problem of short life of traditional bulb light source.
Long Life
Under normal circumstances, the light attenuation of LED can be reduced to 70% of the nominal life span is 100,000 hours, which reduces the replacement frequency and other maintenance work.
Pure light color
Because the spectral range of typical LEDs is relatively narrow, they do not have full spectrum like incandescent lamp. Therefore, LED can be used for diversified combinations at will, especially for decoration and other aspects. Bright, saturated and pure, without filter lens, red, green and blue elements can be used to mix various colors, which can achieve changeable, variable-by-variable, mixed light effect, and excellent color rendering effect. It can realize continuous adjustable brightness, high color purity, dynamic color transformation and digital control.
Moisture-proof and vibration-resistant
Because the exterior of LED is mostly protected by epoxy resin, the sealing performance and impact resistance performance are very good, and it is not easy to damage. It can be applied to underwater lighting.
Flexible dimensions
It can realize the organic integration with the building and achieve the effect of not seeing the light;
Environmental protection
No harmful metal mercury, no infrared and ultraviolet radiation. Characteristics of high-power LED and comparison with other light sources LED is called "green light source" well deserved.
Many changes
LED light source can use the principle of three primary colors of red, green and blue to make the three colors have 256 levels of gray and mix them arbitrarily under the control of computer technology, that is to say, 256 × 256 × 256=16777216 colors can be generated, forming a combination of different light colors and changing multiple ends, realizing rich and colorful dynamic change effects and various images.
Advanced Technology
Compared with the monotonous luminous effect of traditional light sources, LED light sources are low-voltage microelectronic products. It successfully integrates computer technology, network communication technology, image processing technology, embedded control technology, etc. Therefore, it is also a digital information product and a semiconductor optoelectronic devices "high-tech" technology with online programming, unlimited upgrade and flexible features.
Other advantages
Low heat, miniaturization and short response time all make LED light sources have great advantages and create favorable conditions for application in actual production and life.

Insufficient
However, compared with other light sources, LED has disadvantages, such as low color rendering in white light illumination. The color sex Index of white LED produced by yellow fluorescent powder blue light is about 80. As general lighting, it is OK, but it is insufficient for some places with high color resolution requirements. Although the color rendering index can be increased to 90 or higher by adding appropriate fluorescent powder other methods, there is still a certain gap compared with 99 of incandescent lamp, and its efficiency will be affected. The color rendering can also be improved through RGB color mixing, but more work needs to be done in the popularization and application of technology, so the color rendering needs to be improved. As for the high price and large one-time investment, in fact, considering the comprehensive cost, the use of LED in many occasions still saves a lot of costs.
