Osram Opto Semiconductors Releases Oslon Boost HX LED for Digital Projection onto the Road

Osram Opto Semiconductors has introduced the Oslon Boost HX LED. According to the company, the Oslon Boost HX LED can serve as a part of a digital mirror device (DMD) system in an automobile that can project symbols onto the road. Just like a conventional digital projector can show pictures on a screen, a DMD system can use millions of micro-mirrors to project light onto the road in the form of symbols.

The company says that thanks to components including the new Oslon Boost HX, each headlight can achieve a resolution of more than one million pixels, giving automobile drivers optional support from information projected onto the road in addition to convention automotive illumination.

For example, future headlights could project two guide lines the width of a car apart to assist the driver in negotiating road maintenance areas more safely. Projections may also warn drivers that they are too close to the vehicle in front, or notify them that they are approaching roadway maintenance areas, icy patches, or other hazards.

In developing Oslon Boost HX, Osram Opto Semiconductors used its extensive know-how in projection technology combined with it expertise of optimized high-current LEDs. The company transferred these LEDs to the automotive sector and adapted the LEDs to meet the strict quality requirements.

Oslon Boost HX Bright and High Luminance LED

Oslon Boost HX delivers luminance of more than 200 cd/mm², thereby increasing the capabilities for LED-based driver assistance systems and communication with the driver. The unique chip technology with unusually high ampacity allows the chip to operate at 3 A/mm², ensuring high luminous flux or brightness, and most importantly for this target application, high luminance (a measure of brightness over an area). Its 2 mm² chip emits a minimum of 1,400 lm at a current of 6 A.

Osram Opto Semiconductor optimized the package to operate at high current. An electrically insulated thermal pad and a specially structured internal design ensure that heat is removed from the component. The company says that the 4 mm by 4 mm ceramic package is very robust and easy to handle.

Passive DMD solutions may be used for a broad range of applications in the future. The company plans to soon release more efficient active solutions for glare-free high beam and projection, as well as other applications using the Oslon Boost technology.

“This first product in the Oslon Boost family addresses the trend for special user experiences with added safety and emotional appeal. This LED is a good example that shows the enormous potential our products will have in automotive lighting,” said Stefan Seidel, senior manager marketing automotive exterior at Osram Opto Semiconductors.
