Osram aims at outdoor lighting with 2424 chip-scale LED

Osram has put a 2.1 x 2.1mm die into a 2.4 x 2.4 x 0.6mm package to create an LED for outdoor lighting.

Called Osconiq C 2424, “because the package and chip have approximately the same dimensions, it is considered a chip-scale package. This allows the individual LEDs in the luminaire to be placed close together, ensuring particularly homogeneous illumination”, according to the company.

It comes in 70, 80 and 90 CI versions, and 70 CRI types can achieve 328 lm and 167 lm/W at 700mA.

“We specifically designed the Osconiq C 2424 to be compact, while maintaining high brightness and efficiency levels as well as lifetime,” according to the company. “The requirements for lighting solutions vary depending on the desired outcome: from a historic town bathed in pleasant warm white light, to streets and tunnels brightly illuminated for drivers. Thanks to the chip-scale package, the LEDs can be densely clustered, whether it’s for lighting city centres, parks or warehouses.”

An 8kV electrostatic discharge protection device is included in the package.

The company claims the lowest thermal resistance and best colour-over-angle performance for chip-scale LEDs.

Picking a part at random: the GW PLLRA1.EM data sheet shows thermal resistance from junction to solder point is typically 3.5/W, but I cannot find mention of a colour-over-angle figure – Electronics Weekly has asked for clarification.

Typical Osconiq C2424 performance at 700mA is:
