What are the characteristics of the backlight?

1. Higher luminous efficiency: Compared with traditional light sources, LED light sources have higher luminous efficiency. For example, the efficacy of incandescent lamps is generally 12-14 lumens / watt, fluorescent lamps are generally 50-70 lumens / watt, sodium lamps are generally 90-140 lumens / watt, and LED light sources can reach 50-200 lumens / watt, in working condition The light loss rate is lower. Moreover, the LED light source has good monochromaticity and relatively narrow spectrum, and can directly emit colored visible light without filtering.
2. Less power consumption: the backlight is under the same lighting effect, and the LED light source consumes less power compared to other light sources. For example, the LED light source is one ten thousandth of an incandescent lamp, and one half of the fluorescent lamp. . Therefore, in the era when resources are scarce, the light source with so little power consumption can be said to be the needs of people and meet the needs of people.
3. Longer life: LED light source is small in size and light in weight epoxy resin package, can withstand high-strength mechanical shock and vibration, and is not easy to break. Conventional LED light source life is about 5-10 years, which greatly reduces the cost of midway replacement and reduces overall maintenance costs.
4.More security: LED light source has low calorific value and no heat radiation. It belongs to cold light source and does not contain mercury, sodium and other substances that may be harmful to health. The safety is relatively comparative.
