Osram Develops New LED for Ultra-slim Headlights

Car lighting has come to be an important part of the overall design of a vehicle. Osram has come up with a new product called Oslon Boost HM which delivers impressive brightness values with compact dimensions.

Smaller and brighter light sources are needed in order to design headlights which are more compact and versatile. In line with the trend of making headlights which are compact without in any way compromising the quality of light delivered, the powerful Osram Oslon Boost HM helps design headlights which are ultra-slim.

The miniaturization of the LED light is useful for the delivery of adaptive front lighting, which is also known as bend lighting or matrix lighting. Another laudable achievement that the Osram team made with the development of this product is that they were able to attain an outstanding brightness of 415 lm at 1.5 A even with a very small chip area of just 0.5 square mm.

Even the packaging of the LED is also compact with dimensions of 1.9 mm x 1.5 mm x 0.73 mm, thus providing a finger-width front headlamp solution, without affecting the light output. The luminance of 255 cd/sq. mm at 1.5 A is an absolute best-in-class performance value for this type of LED.

In addition to being used for headlamps, the Oslon Boost HM can be used in combination with other LEDs for providing an additional high beam. The LED can also be used in MEMS-based adaptive front lighting systems due to its outstanding luminance. Osram Opto Semiconductors leveraged its many years of expertise in package design to create this new product. The strong ceramic package of the Oslon Boost HM facilitates easy thermal management within the component with the aid of an electrically insulated pad. The special internal design structures make it possible for heat to be easily dissipated from the LED. Furthermore, the LED shines with a particularly low thermal resistance of only 4.62 K/W.

“With the Oslon Boost HM, we are not only expanding our Oslon Boost product family to include particularly high luminance levels but are also helping our customers create ultraslim headlamp designs,” explained Florian Fink, Marketing Manager for Automotive Exterior at Osram Opto Semiconductors. “Thanks to our products, future vehicles will feature a ‘new face’.”
