Since the advent of the LED semiconductor light-emitting chip technology in the 1960s , as a cold light source with energy saving and no radiation, it has become the development trend of future energy. Through the unremitting efforts of science and technology workers, the color of the light has evolved from the initial red color to the current red, orange, yellow, green, blue and other color lights. However, the LEDs that need to emit white light have only developed in recent years. LED lights are expected to lead the revolution in lighting history after incandescent and fluorescent lights. Experts predict that China from 2005 to 2015, cumulative semiconductor lighting energy-saving 400 billion kWh, for users to save electricity costs of 260 billion yuan, 150 billion yuan output value creating, solving the employment population of one million.

LED lamps have high luminous efficiency and long life, and their luminous efficiency can reach 2.5 times that of fluorescent lamps and 13 times that of incandescent lamps . The luminous efficiency of incandescent lamps is very low, only 5% of the electrical energy is converted into light energy, and 95% of the electrical energy is turned into heat. Fluorescent lamps are better than incandescent lamps, with 20% to 25% of electrical energy converted to light energy, but 75% to 80% of electrical energy is wasted. Therefore, from the perspective of energy utilization efficiency, the utilization efficiency of these two light sources is very low.

Although the current price of LED fluorescent tubes is still high, due to its characteristics of energy saving, environmental protection and long life, it has gradually been applied in parking lots and commercial lighting. Although China's LED fluorescent tubes are not the largest in China's LED indoor lighting products, the market size is the largest among indoor lighting products, and this trend will be maintained for the next few years.

1. Service life: The service life of LED exceeds all other light sources. For example, in normal home environment, LED can be used for up to 20 years.

2, energy costs: LED power consumption is very low, LED components, such as OSRAM Opto Semiconductors Golden DRAGONPlus reached luminous efficiency 110lm / W. LED lights only need about 6W to generate the equivalent of 25W incandescent light;

3 , dimming function: LED can be dimmed to further reduce energy consumption;

4 , no mercury: LED does not contain mercury or lead, reducing the cost of disposal;

5 , efficiency: Today's LED efficiency has been about 5 times higher than incandescent lamps , with the continuous advancement of technology, the future efficiency will be 10 times higher. In theory, LED technology can save more than half of the power consumed by artificial lighting.
