Full LED headlight replaces halogen originals

US automotive firm Peterson Manufacturing entered the LED headlamp market with an all-LED main/dip replacement for 7inch (PAR56, 175mm) headlights, based on new Osram LEDs.

Called 701C, it uses two Ostar Headlamp Pro LEDs, firing sideways into separate main and dip reflectors.

With a move to a Pro version, Osram has done away with the glass die cover used in the earlier non-Pro Ostar Headlamp LED, and instead encapsulated the die and bond wires in an elastomer.

 “With luminance of 40×10(super6)cd/m(super2) and a radiating surface of 5.5mm, the five chip version is an ideal solution for automotive exterior lighting. It easily achieves the same output as a halogen lamp and is an important milestone in LED performance,” claimed Osram.

The complete Peterson headlight includes a built-in 9-32V (1.9-0.7A) power supply making it compatible with both 12V and 24V systems.

“Unlike some competitors’ lights, which claim to be direct PAR56 replacements, 701C has its standard H4 three-blade terminals integrated into the housing, not wired onto the light as a separate pigtail,” said Peterson.

Peterson designed and is making the lamp in Missouri, with Munich-based Osram collaborating in developing that initial concept and provided optics support and thermal simulation.
