Panasonic push GaN based white LED to improve the freedom of headlight design

Panasonic on the "electronica 2014" on display for the car headlights LED. Panasonic's white LED is characterized by the blue LED chip is manufactured on a GaN substrate. Compared with the usual sapphire substrate, it is easier to improve the current density.

Since the current density can be increased, a smaller chip size can be obtained with the same brightness as the product of the sapphire substrate. In this way, the front lamp of the car can be miniaturized, which is helpful to improve the design freedom of the headlight part.

In addition, Panasonic also exhibited the necessary MCU and LED drive white DC-DC converter. "Our advantage is that we can provide not only LED, but also digital products such as MCU, as well as analog products such as DC-DC converters," said the commentator". With this advantage, Panasonic car LED products have begun to be adopted in the European market.

The car LED is next to the vehicle equipment with a cooling fan display. "To do so, is to let everyone know about our entire thermal design, that is, from the LED this heat source, that is, the entrance of the heat, until the heat dissipation fan of the design of the export. We hope to emphasize that the use of our white LED and drive components, and combined with the cooling fan and (in addition to display) heat dissipation graphite sheet, can make the design of the LED car headlights easier".
