Silicone lenses enable compact vehicle lighting
Matrix light not only contributes to greater road safety but also gives headlight designers greater freedom thanks to its smaller dimensions. This technology is therefore very much on the march. To meet the demands of the automotive industry for more and more compact smart headlights Osram has taken this technology an important stage further with the development of innovative SMARTRIX modules. SMARTRIX is an amalgam of “smart” and “matrix”. “By using new materials for the lens systems we have could make the SMARTRIX modules even smaller and more durable”, explained Hans-Joachim Schwabe, CEO Specialty Lighting at Osram. The compact form factor translates into more design freedom for headlight designers the Schwabe added.
Matrix headlights provide excellent visibility at night and poor weather conditions. The smart distribution of light ensures that the road is illuminated with a high level of precision and maximum light output without dazzling oncoming drivers. Several individually controllable LEDs are combined into a matrix (array) with common optics. The LEDs can be controlled individually, “pixel by pixel”, so specific areas of the road and its environs can be illuminated or masked out as required.
The standard plastic lenses which have been used for matrix systems in the past did no longer meet the requirement to be placed closer and closer to the light source. Osram therefore looked for a new material for the lenses and developed the SMARTRIX modules which are equipped with lenses made of silicone as this material emerged as the best alternative to plastic. The lenses offer properties such as long life and high resistance to heat and radiation, and are also less expensive than glass lenses. In addition, silicone lenses can be attached directly to the LEDs, making the product much smaller overall. Headlight designers have much greater freedom as a result and can more easily follow the trend for narrow low-profile headlights.
First-generation SMARTRIX modules from Osram will appear on the roads in the fall of 2017. The company said it is already working on the next generation which will offer multi-line matrix functionality in one module, and the chance to make headlights even more compact.
