What are the advantages and disadvantages of led lights in home lighting?

Advantages: (1) long working life: LED as a conductor solid light-emitting device, compared with other light-emitting appliances have a longer working life. Its brightness half-life can usually reach 100,000 hours. If you use LED to replace the traditional automotive lights, then its life will be much larger than the life of the car body, with a lifetime without repair and replacement.

(2) low power consumption: LED is a low-voltage devices, so in the same brightness, power consumption is minimized, can reduce energy consumption. On the contrary, with the future development of processes and materials, will have a higher luminous efficiency. People have done calculations, if all of Japan's lighting fixtures with LED replacement, it can reduce two large power plants, thus very favorable to environmental protection.

(3) fast response time: LED can generally respond in a few tens of milliseconds, so it is a high-speed device, which is beyond the reach of other light sources. The use of LED to make the car's high brake lights at high speed, greatly improving the safety of the car.

(4) Small size, light weight, impact resistance: this is the inherent characteristics of semiconductor solid devices. So LED can be made to all kinds of clear and delicate display devices.

(5) Easily dimmable, color-adjustable, controllable: LED as a light-emitting device, you can control the brightness by the change of the current flowing through it, and also through the configuration of different wavelengths of LEDs to achieve the color change and adjustment. Therefore with LED composed of light source or display, easy to electronic control to achieve a variety of applications, and IC computer in the compatibility of incomparable difficulties. In addition, the application of LED light source is not limited by manhole in principle, plasticity is very strong, can be extended arbitrarily, to realize the building block type assembling. The current large-screen color display is not LED.

Disadvantage: the price is too high, the general public is difficult to accept. However, with the development of technology and strong government support. led energy-saving lamps will surely replace the traditional lighting.
