What are the advantages of LED light source

time:Mar 16, 2022 Views:


As a light-emitting device, the reason why LED has attracted much attention is that it is superior to other light-emitting devices. To sum up, LED has the following advantages:

(1) Long working life: As a conductor solid-state light-emitting device, LED has a longer working life than other light-emitting devices. 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 small, which can greatly reduce 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: LED can generally respond within tens of milliseconds (ns), so it is a kind of telling device, which is beyond the reach of other light sources. The use of LED to make the high-position brake light of the car improves the stability of the car at high speed.

(4) Small size, light weight, and resistance to resistance: This is the inherent characteristic of semiconductor solid-state devices. Color LED can make all kinds of clear and delicate display devices.

(5) Easy dimming, color matching, and high controllability: As a light-emitting device, LED can control the brightness through the change of the current flowing, and can also realize the change and adjustment of color 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 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.
