White LED headlamp luminous efficiency will exceed HID lamp

Stanley electric (STANLEY ELECTRIC) at the Tokyo auto show, the exhibition will be high power white light emitting diode (LED) for dipped beam and high beam headlights products. Speaking with white LED lamp, lamp manufacturers exhibited in the recent exhibition, the use of white LED module, then use the HID lamp in the headlights on products only in the last. The show also appeared in the high beam is also the use of white LED module trends, leaving a white LED module is moving toward the impression of high-power. All products of the white LED module with optical lens under the condition of diameter were 30mm ~ 50mm, as LED belongs to the larger varieties.

The headlight Stanley Electric is on display with the German company Hella (Hella KG Hueck&Co.) joint development. Production will be 4 large LED chip package into a high-power white LED module, this module is equipped with 5 headlights, in the last with 2. The light beam when the total of 700lm, according to reports "can ensure the brightness of the HID lamp just listed" (Stanley electric commentator). Each white LED module emits a beam of about 140lm. The company did not announce the electric power production, but at this stage in order to ensure the necessary brightness as the headlamps, HID lights and electric power consumption of the same brightness products compared to the estimate is 1.4 times to 1.6 times of the latter. According to Stanley electric, white LED luminous efficiency has slowed in the past period of time, but recently restored momentum. Estimated before and after 2008 will reach and exceed the luminous efficiency of HID lamps.

The headlight on the exhibited in the development, until the package of LED chip, are used in electrical technology developed by Stanley, the packaging of optical technology to produce a headlamp required is jointly developed by Stanley electric and Hella company. It is said that according to Hella proposal, on the packaging technology was improved.
