In addition to energy saving, LED another property is what?

Review: in the context of global energy shortage worries again warming, LED highlights the growing application prospects. However, in addition to energy saving, another property of LED has not yet attracted enough attention, sponsored by the Shanghai Municipal Association for science and technology in the interpretation of yesterday's 2014 Nobel prize in physics activities, Professor Zheng Yuxiang Department of Optical Science and Engineering School of information science and engineering Fudan University pointed out that LED is in control of the future will bring change to human lighting, research this should strengthen.

LED chip can control the lighting effect

Japanese scientist Akasaki Yong, Amano Hao and Japanese American scientist Nakamura Shuji invented the Blu ray LED, brought mankind into the information age in the lighting, fluorescent lamp in twentieth Century compared to 70 lumens / watt lamp, LED lighting efficiency is more than 4 times. It is said that Saunders, director of the British Institute of physics, said that the current world lighting consumes more than 20% of the electricity supply, the use of LED bulbs, this ratio dropped to 4%. This considerable energy saving figures if coupled with the controllable properties of LED, but also to tap 30%.

LED control can save the manpower cost, now if the street lamp lights, maintenance personnel need a beacon with eyes to see, the future by setting within the LED chip, it is easy to know the first few rows which street lights did not meet the specified requirements.

The brightness of the demand for lighting is constant, the so-called smart is the brightness of indoor lighting can be automatically changed according to the changes in the sun, through the sensor, people can not even feel the presence of light. When people come home at night, the lights turn on and the lights turn off automatically when the day is bright enough, and when the brightness is not enough, the lamp will automatically fill up enough light.

These future scenarios need to be achieved through intelligent control, the key lies in the control chip. Chinese Academy of Sciences, Shanghai Institute of Technical Physics researcher Zhang Tao pointed out that in the control of the LED, we must have vision, imagination.

LED will be part of the material

The scientist's imagination, LED development into the future is a part of the material, that is to say, the future of "light" will exist in name only. The advantage of semiconductors is that you can make any shape according to any of your ideas and put it anywhere you want it to be. In this concept, perhaps in the future we will be in a room during the day to see the walls and ceilings, when the night comes, a certain area of the ceiling will be lit up. The future is not to go to the LED market to choose the light, but to choose the material market you want to shine area. This concept has been presented to everyone in World Expo, an exhibition of life in the future.
