LED on the technology innovation system and solar power type silicone

Recent light-emitting diode (LED) has gradually become the mainstream lighting equipment, Japan is committed to the development of new products, hoping to become a new market winner. Japan's University of Tokyo professor Otsu Shimotochi and special researcher Kawa Tada developed the new silicone LED, and the gallium nitride (GaN) products will be more than the brightness increased by 3 times, the material cost is only 1/40. In the future, University of Tokyo will work with lighting equipment manufacturers to promote practical.

LED is usually used with a small amount of indium gallium nitride (Indium) substrate, but otherwise the University of Tokyo research team's ingenuity, deliberately used the large scale integrated circuit (LSI) and other products commonly used silicone as crystalline substrate. Silicone materials of the original electricity is not light, but a small amount of boron, beginning with luminescent properties. At present, the research team has been trying to make yellow and red light of 2 LED, and also the use of silicon carbide substrate with silicone similar make Blu ray LED.

In 1 square centimeters, providing 1 amperes of current under the same conditions, LED and LED Silicone Market 1 watt power ratio is 0.2 lumens and 0.6 lumens; in addition, the LED is making on GaN dot luminescence, and silica gel system is full light, easily making lighting equipment.

On the other hand, Japan Dongyang building materials factory on the village of Advance LED also developed solar power lighting equipment type, even in bad weather, can maintain the normal illumination, suitable for a power supply device is not easy parking lot or apartment corridor.

Solar LED electronic IC will automatically control loading, storage, and night illumination, can effectively prevent the depleted of bad weather, unable to maintain the lighting problem; using solar LED global NAND giant Toshiba Flash (Toshiba) of the lithium battery products, in exchange for a period of about 10 years. Including the set of pillars, the tentative price of about 500 thousand yen (about $6030).
