Compared with traditional light sources, what are the advantages of LED light sources?
As a light-emitting device, the reason why LED has attracted much attention is that it is superior to other light-emitting devices.
Nano LED has the following advantages:
(1) Long working life: LED, as a conductor solid-state light-emitting device, has a longer working life than other light-emitting devices
life. Its brightness half-life can usually reach 100,000 hours. If LED is used to replace traditional car lights, its lifespan will be much longer than that of the car itself, and it has the characteristics of no need to repair and replace it for life.
(2) Low power consumption: LED is a low-voltage working device, so under the same brightness, the power consumption is the smallest, which can be greatly reduced
energy consumption. On the contrary, with the development of technology and materials in the future, it will have higher luminous efficiency. It has been calculated that if all lighting fixtures in Japan are replaced by LEDs, two large power plants can be reduced, which is very beneficial to environmental protection.
(3) Fast response time: LEDs can generally respond within tens of milliseconds (ns), so it is a kind of telling device, which also
It is beyond the reach of other light sources. The use of LED to make the high-position brake light of the car greatly improves the overall performance of the car at high speed.
(4) Small size, light weight, and resistance to resistance: This is the inherent feature of semiconductor solid-state devices. Color LEDs can be made of various types
Clear and refined display device.
(5) Easy dimming, color matching, and high controllability: LED, as a light-emitting device, can pass the change of current flowing through it.
The brightness can be controlled, and the color change and adjustment can also be realized through the configuration of LEDs with different wavelengths. Therefore, the light source or display screen composed of LED is easy to meet the needs of various applications through electronic control, and it is extremely difficult to be compatible with IC computers. In addition, the application of LED light source is not limited by scenting in principle, and it has strong plasticity and can be extended arbitrarily to realize building block assembly. The current large-screen color display is none other than LED.
(6) The light source made of LED has no environmental pollutants such as mercury and lead, and will not pollute the environment. Therefore, it is well-deserved to call LED light sources a "green" light source.
