ams Osram claims brightest LED for automotive front lighting

ams Osram has claimed the brightest LED currently available in the market for automotive front lighting. Designed for standard low- and high-beam headlights, the new Oslon Black Flat X family offers brightness of 460 lumens at 1 A and is available in 1- and 2-chip versions. The 1-chip variant is housed in a small 3.75 × 3.75-mm package.

The leadframe-based LEDs feature a “special” QFN platform that enables simple thermal management, said ams Osram. Depending on the system, heat sinks can be either significantly reduced in size or eliminated. The leadframe package also is said to achieve a lower thermal resistance (Rth) than the leading ceramic packages.

Together with a special TiO2 encapsulation, the black package of the LEDs offers high contrasts of 1:200. They also are characterized by a very homogenic color over angle radiation, due to the dielectric coating, said the company. The operating temperature range is -40°C to 135°C and the maximum junction temperature is 150°C.

The Oslon Black Flat X family is available now in 1- and a 2-chip versions. The company expects to add multi-chip variants in mid-2022.

Last year, ams Osram expanded its Oslon Black Flat S family to include one- and two-chip versions. The family also features the special leadframe–based design, with the highest contrast values (>1:200) and very low thermal resistance, which allows for higher currents. The one-chip variant achieves 395 lumens at 1 A. The square lighting surface of the UX:3 chip makes optical design particularly easy for headlight manufacturers, said the company.
