Stanley electric by the end of 06 production 180LM white LED

Japan Stanley electric display of 180LM can be obtained in 6W power (Liu Ming) white light-emitting diode (LED). Mainly for automotive headlamps, lighting appliances and LCD backlight, etc., plans to start mass production in December 2006. It is made up of blue LED chips and yellow fluorescent material, which can produce white light by mixing blue and yellow light. The exhibition company discloses the white LED with the use of the lens module, and the module uses the street lamp and headlight products.

In order to get high brightness 180LM beam in high power white LED, in the use of ceramic packaging to improve the heat dissipation, while the 4 LED chips embedded in a package. In addition, in order to send out the light emitted by the LED with high efficiency, the reflector is arranged inside the package. Thermal resistance from the LED chip junction to the lower part of the package is as low as 3K/W. The package size is 5.9mm * 11.5mm * 1.1mm, the luminous part area is 2.4mm * 5.6mm. Blue LED chips purchased from other companies.

Stanley electric in its exhibition area of high power white LED development blueprint. According to the blueprint, by the fourth quarter of 2008, the luminous efficiency of 4.5W power will reach comparable to the standard 70lm/W fluorescent lamp. The prototype for the 30lm/W standard, however, will be increased to more than 2 times. The company said: is constantly improving LED chip, to achieve this goal is full of confidence.

Stanley electric also demonstrated the use of UV LED chips of high power white LED, as well as the white LED package together with red, green and blue LED. In terms of the varieties of UV LED chips, the average color evaluation index is 88. Combined with red, green and blue 3 fluorescent materials, white light can be obtained. The beam brightness can reach 70lm under 4.9W power. UV LED chips produced by the company. However, the production date has not yet been determined. The red, green and blue LED plans to start mass production in December 2006.
