2013 annual LED lighting technology

In 2013 the LED industry can be said to be volatile, and it is also an important period of the industry, the first is the LED energy subsidies not to continue, then LED industry bosses run away, LED industry closures of small and medium-sized enterprises, but this does not affect the direction of technology development of LED lighting, energy saving and low carbon industry is the constant theme of the network for you 2013 LED lighting technology inventory.

Synthetic biology technology "luminous plants"

In the United States of San Francisco, Dr. Omri Emino Chari, synthetic biology and botany Dr. Kyle Taylor technology entrepreneur Anthony Evans was put up a pageantry common research and development of "light plant" project. On their website, they said they would like to provide you with a more natural, energy-efficient lighting, one day let everyone say goodbye to the light bulb. They used a synthetic biological technology will transplant the firefly luciferase gene on the body into the plant body, through improved design and control of gene expression, has been called a can let Arabidopsis plants emit fluorescence when compared to the previous research achievements of other similar more bright. In the future, they want to be able to develop sustainable lighting plants for street lighting, and the technology used in areas such as flower gardening.

Two, potato battery light LED lamp technology application

Rabinowitch said: "a potato produces enough energy to make a room LED light on the 40 day. "It sounds absurd, but it is based on science. Rabinowitch and his team have found that, in fact, in the real world to start a potato supply project is quite complex. In order to use organic materials to make a battery, you need two metals: zinc, such as an anode and copper as a cathode. Potatoes are usually the best choice to demonstrate this principle in school. To Rabinowitch's surprise, however, no one has studied potatoes as an energy source. In 2010, he decided to collaborate with Dr. Alex Goldberg and Boris Rubinsky of the University of California. They found that by boiling the potatoes for 8 minutes, they would break down the organic structure inside the potatoes, reduce the resistance and make the electrons move more freely, resulting in more energy. "We found that we were able to increase the output by 10 times, which makes it very cost-effective," Goldberg said. "

Three, in the LED bulb can be replaced by the chip WIFI

It is understood that the relevant information from the school of information science and engineering, Fudan University, a research group, they have successfully experimented with a visible light transmission network information technology (LiFi). The researchers not only to achieve the use of visible light transmission network signal in a laboratory environment, and the implementation of the "one to four": the network signal access a 1W LED chip, under the light of the 4 computer to the Internet, offline the highest rate of up to 3.25G, the average speed of real-time system on the rate of up to 150M, the world's fastest the lights on the internet". Group of experts believe that, compared with the existing WiFi, the future of visible light communication security and economy. WiFi network security risks exist, in the visible light communication will be wiped out". Moreover, the "light on the Internet" means greater bandwidth and higher speed, network settings do not need any new infrastructure.

Four, the new LED lighting system for street lamps more energy saving

According to reports, there are currently a group composed of two words Chinese Taiwan and Mexico researchers have developed a new lighting system, the system through the efficient use of LED, can ensure that the lamp illuminates only need light, without generating unnecessary light. "A unique feature of this new LED system is that it can adapt to different street street layout, to provide efficient lighting for a variety of streets and roads," participate in the study of science and engineering, National Central University China photoelectric said Professor Sun qingcheng. The new street lamp system consists of three parts. The first part consists of a string of LEDs, each equipped with a known as total internal reflection (TIR) lens device, its role is to bring together the light, precise control of the direction of the beam of light emitted in parallel without mutual cross. The researchers use the light utilization rate (OUF) to quantify the performance of the street lamp, the higher the light utilization ratio, the better the performance of street lamp. The results of computer simulation show that the light utilization ratio of the new street lamp system can reach 51% to 81%, which is far more than that of the ordinary street lamp at present. The results show that this method can be used for more than 45%.

Five, high efficiency LED road light utilization rate of 81%

National Central University professor Sun Qingcheng research team developed a "micro structure diffusion", the successful development of a high efficiency LED lamp, light source irradiation characteristics are the concentrated on the road, to avoid playing into the night sky, homes caused by light pollution. The leading global technology, optical utilization of up to 81%, better performance than traditional street lamps and general LED street lamps. Sun Qingcheng said that the traditional lamp optical utilization rate of only about 20%, generally about 45% LED street, representing most of the light is wasted, not to be guided according to the road, and the light shines into the sky, around the house, the formation of light pollution, a common sight is the sky and the lamp is bright, but the road not very bright.

Six, with LED lighting intelligent hospital lighting system"

Saitama prefectural Cancer Center Hospital of new Japan Murata is completed in July 13th, set up a "hospital intelligent lighting system, and put into use on the same day. By using the wireless switch and lighting control device which can send the signal without the need of the battery, the intelligent hospital lighting system realizes the illumination of the circadian rhythm. Circadian rhythm refers to a circadian rhythm of about 24 hours. Lighting system will be 1 talent for the time period, the use of LED lighting light day and night performance changes, so that the life cycle of hospitalized personnel remained stable. LED lighting control helps to achieve energy saving, the use of pre simulation results show that, compared with the control and output power of the same LED lighting, up to 30% energy reduction. Compared with fluorescent lamps, can reduce the energy of about 90%.

Seven, Hefei took the lead in the use of sunlight, lighting the light guide system

Hefei hi tech Zone in the government investment in the construction of affordable housing, the first to introduce the new energy-saving lighting technology. At present, in addition to the reported revival of home projects, Yonghe home three and Nangang, the construction of the second point of the project is also the application of the new technology of the two. According to reports, the light guide is the direct use of spectral lighting system to introduce the sun we need to place the lighting, direct use of sunlight to reduce carbon emissions, improve the living environment purification. Preliminary estimates, the three District installed a total of more than 630 sets of light guide system, a unit price of about $2000, the total cost of about 500 thousand yuan (if replaced with fluorescent lamps, about the need for 5040). The use of the new technology, about 10 hours during the day without electricity, the annual savings of about $800 thousand in the District of about $three.
