Lighting factories share the nine characteristics of LED lights as follows:
Voltage: LED uses low-voltage power supply, the power supply voltage is between DC-V, depending on the product, there are also a few DCV, DCV, etc., so it is a safer power supply than using high-voltage power, especially suitable for public places .
Efficacy: Energy consumption is reduced by% compared to incandescent lamps with the same luminous efficiency
Applicability: The volume is small, each unit LED chip is -mm square, so it can be prepared into various shapes of devices, and is suitable for variable environments
Color: Light-emitting diodes can easily adjust the energy band structure and forbidden band width of the material through chemical modification methods to achieve red, yellow, green, blue and orange multi-color light. The working voltage of the red light tube is relatively small, and the working voltage of the red, orange, yellow, green, and blue light-emitting diodes of different colors increases sequentially.
Price: The price of LEDs is becoming more and more commonplace. Due to the power-saving characteristics of LEDs, perhaps in the near future, people will replace incandescent lamps with LED lamps. Some urban roads, schools, factories and other places in China have been replaced with LED street lamps and energy-saving lamps.
Stability: Ten thousand hours, the light decay is the initial%
Response time: The response time of the incandescent lamp is milliseconds, and the response time of LED lights is nanoseconds
Environmental pollution: no harmful metal mercury
Type Development
The first LED light source made using the principle of semiconductor P-N junction light emission came out in the early century. The material used at that time was GaAsP, which emits red light (λpu003dnm). When the driving current is milliampere, the luminous flux is only a few thousandths of lumens, and the corresponding luminous efficiency is about lumens/watt.
In the middle of the year, the elements In and N were introduced to make the LED produce green light (λpu003dnm), yellow light (λpu003dnm) and orange light (λpu003dnm), and the luminous efficiency was also increased to lumens/watt.
At the beginning of the decade, GaAlAs LED light sources appeared, making the light efficiency of red LEDs reach lumens/watt.
At the beginning of the years, two new materials, GaAlInP, which emits red and yellow light, and GaInN, which emits green and blue light, were successfully developed, which greatly improved the light efficiency of LEDs. In 2000, the LED made by the former can reach lumens/watt in the red and orange zone (λpu003dnm), while the LED made by the latter can reach lumens/watt in the green zone (λpu003dnm).
