Osram has developed Smartrix modules with silicone lenses to enable vehicle lighting systems to be small and compact.
“By using new materials for the lens systems we have been able to make the Smartrix modules smaller and more durable, so our customers have more freedom in designing headlights”, said Osram Speciality Lighting CEO, Hans-Joachim Swabe.

Matrix headlights ensure 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.
Smaller modules mean new headlight designs:
Standard plastic lenses which have been used in the past few years for matrix systems could no longer meet the requirement to be placed closer and closer to the light source, maintains Osram.
It 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 autumn this year.
