What Are The Advantages Of LED Light Source?

- Mar 10, 2018 -

As a light emitting device, LED has attracted much attention and has its advantages over other light-emitting devices. It is concluded that LED has some of the following advantages:

(1) long working life: LED is a kind of conductor solid light emitting device, which has longer working life than other light emitting devices. The half-life of the luminance usually reaches one hundred thousand hours. If LED is used to replace the traditional automobile lamp, its life will be far greater than the life of the body of the car, and it has the characteristics of long life without repair and replacement.

(2) low power consumption: LED is a low-voltage working device, so in the same brightness, power consumption is minimal, and energy consumption can be reduced. 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 Japanese lighting fixtures are replaced by LED, two large power plants can be reduced, which is very favorable for environmental protection.

(3) fast response time: LED generally available in tens of milliseconds (NS) in response, so it is a device that is told, other than light. The high position brake lamp that uses LED to make the car in the high speed state greatly improves the safety of the car.

(4) small size, light weight, resistance to resistance: This is the inherent characteristic of semiconductor solid device. Color LED can make all kinds of clear and delicate displays.

(5) it is easy to adjust light, color and control. As a light-emitting device, LED can control brightness through the change of current, and also can achieve color change and regulation through different wavelength LED configuration. Therefore, the light source or display screen made up of LED is easy to use electronic control to meet the needs of various applications. It is very difficult to be compatible with the IC computer. In addition, the application of LED light source in principle is not limited by scenting, the plasticity is very strong and can be extended arbitrarily. At present, the color display screen of the large screen is not LED.

(6) the light source made with LED does not exist such as mercury, lead and other environmental pollutants, and will not pollute the environment. So people call LED light a "green" light source to be well deserved.
