OSRAM photoelectric August 1st began to market high power infrared LED

OSRAM Semiconductors semiconductor (OSRAM Opto GmbH) released a car infrared night vision system (night vision and night surveillance cameras, etc.) using high power infrared LED OSTAR Observation". In Japan, will be listed in August 1st 07. The luminous wavelength is 850nm. Optical power for the standard 3.6W or 3.0W (input current is 1A), is the same wavelength of the company's original product (standard 440mW) 7 ~ 8 times. According to the company said that other companies produce infrared LED optical power of 40 ~ 50mW, the product is its dozens of times. Before the company has released the product, in the 07 years from 11 to July 13, Messe held Inter Opto Makuhari'07 "made products.

Power of 3.0W "SFH4730" will be in the light beam farther down the effort. By coating the frame around the infrared LED chip to reduce the reflected light, infrared light can be emitted from the chip area (Figure 1). As a result, the infrared LED chip installed on the top of the lens, it is easy to gather infrared. 3.6W power SFH4740 belongs to the pursuit of power products. The frame around the infrared LED chip is painted white, and the infrared light is reflected back onto the frame, thereby reducing the loss of infrared (Figure 2).

All products are packaged in 33mm x 13.5mm x 4.6mm. Each product is equipped with 10 1mm square size infrared LED. Infrared LED chip using OSRAM LED technology Thinfilm". In the infrared ray generated by the light-emitting layer in the chip, more than 97% of the infrared radiation from the surface of the chip to the outside can effectively irradiate the front of the chip. The infrared LED thermal resistance is 2.8K/W. Sample price of 10 thousand yen.

Expected to be used with LED headlamps

OSTAR Observation is expected to be equipped with 2010 to 2011 or so on the market car. Among them, the greater the possibility that the use of LED headlamps on the car's night vision.

At present, the use of infrared night vision is generally halogen lamps and infrared projector with the use of infrared radiation. Such as the use of LED headlamp TOYOTA "Lexus LS600h" used in the infrared radiation is the halogen lamp. In the future, all the light source in the front of the LED is realized, and a new infrared light source is needed. To meet this demand is the OSTAR Observation. The original infrared LED power shortage, it is difficult for the exposure of distant objects.
