LED headlamps increased volume of OSRAM, Audi, a total of new products

In the world's largest electronics industry exhibition "Electronica a day before the 2014 opening (November 10, 2014) and" Electronica Automotive Conference "seminar held on the Germany OSRAM Opto Semiconductors (OSRAM Opto Semiconductors) Claus Allgeier speech, introduced the development situation of this company is engaged in the automobile headlight.

In his speech, Allgeier first stressed that the amount of LED headlights are increasing year by year. "The original luminous efficiency is the main factor to promote the use of LED headlights, but recently, the excellent modeling degrees of freedom has become a new driving force". At the same time, the LED headlights are widely used, the standard products on the Volkswagen car equipped with high-end products and the beginning of polarization.

High grade car is equipped with a LED light that can be adjusted according to the external environment. Implementation of the method is to configure multiple LED array, according to the external environment to open or close these LED.

OSRAM in 2013 to achieve practical array LED, is 15 ~ 25 LED in a row. Scheduled in 2016 to 2017 put into use of the product will further increase the number of LED, intends to arrange the two LED into a two-dimensional matrix (20 * 5). In fact, OSRAM is working with Audi and Infineon Technologies jointly developed with 100 LED products.

In 2020 to achieve practical products to further increase the number of LED. According to reports, this product hopes to achieve a new feature, which is not only for vehicles and vehicles in front of the vehicle, such as dimming, but also take into account the pedestrian dimming.

Not only is LED, OSRAM is also vigorously developing semiconductor laser headlights. This kind of head lamp uses blue semiconductor laser to excite phosphor to obtain white light, already equipped with Audi "R8 LMX" and BMW "I8" on.

OSRAM at the Electronica Conference on the display of laser headlights and laser head used in the blue semiconductor laser PL TB450B". The oscillation wavelength of the laser is 450nm + 10nm, and the output power is 1.6W, which is a multi-mode product, which is packaged in TO56.

In addition, there has been a trend in the use of organic light EL taillights. One of the reasons for the adoption of organic EL is that the flexible substrate can be used to realize the three-dimensional structure.
