LED Light Bulb

Have you ever seen a city with LED lights? LED lights can be found in most cities in China. They are very popular. You can see LED streetlights on roads and streets, LED billboards outside every street shop, and LED light bulb in every house and building. However, why do citizens buy LED light?
 First of all, LED light contributes to the environment greatly. It has good solidity, anti-shock performance and impact resistance. Therefore, it is durable and will not pollute the environment and people will buy LED light for their home decoration.
Secondly, the LED light has been improved technologically for decades, so its luminous efficiency has been improved to a large extent. The LED light has nearly seventeen times luminous efficiency over that of halogen light, and up to triple luminous efficiency over fluorescent light. The monochromatic light is good with narrow spectrum and can be visible without the color filters.
Thirdly, the LED light can consume less electricity. The driven voltage can be as low as 1.5V, and the current can be 15-18milliamperes. Since the light has a high reaction speed, it can be operated at high frequency. Estimated by Japanese experts, its power consumption can be one-eight of incandescent bulbs. So most people buy LED light crazily.
Fourthly, the LED light can be safely touched because of its low heat, non-thermal radiation and cold light. It is soft in color, light in weight, and non-glare. It also contains no mercury, sodium and other hazardous elements. In addition, it has a built-in micro-processing system, thus users are able to control the luminous intensity and adjust the light-emitting modes to achieve the best light.
Furthermore, the LED light has a longer life span over other lights. Unlike electronic radiation emitting lights, LED light will not burn the filament, therefore avoiding optical attenuation. In addition, because of its small size, tiny weight, epoxy package and its excellence in withstanding high-intensity mechanical shock and vibration, it can be hardly broken. The average life span can be 25,000 hrs. This is the most reason why the people buy LED light.
As a result, the LED light bulbs, LED streetlights and LED billboards are widely used in cities and towns in China. The fact is that Chinese people are looking for more and more ways to make contributions to the environment, so why not buying LED light now?
