Osram high-flux OSLON black flat headlamp LEDs, in distribution
Osram OSLON Black Flat LEDs are small, high-flux light emitting diodes (LEDs) that pack robust brightness and high stability in a slim SMD-4 epoxy package. The LEDs are built on gallium nitride-based UX:3 chip technology, which generates very high luminous flux even at high currents. This brightness is emitted from a comparatively smaller package, which enables very compact headlamp designs. Designed with surface mount technology (SMT), the LEDs can be mounted on a printed circuit board and then processed further as part of standard soldering procedures. This soldering capability enables the LED to be integrated in a simple,
standardised process and reduces the complexity of the processing steps, which saves considerable time and costs compared to previous multichip LEDs. The black QFN package expands in a similar way to the circuit board during cyclic temperature loads, meaning that the soldered joints are exposed to much less strain and are significantly stronger.
The 500-lm KW H2L531.TE model LED has a low thermal resistance of 1.6 K/W (typical, LED only), a luminous intensity of 174.9 cd, and a colour chromaticity of 0.32 (Cx) and 0.33 (Cy) according to CIE 1931. The 250-lm LUW HWQP model LED has thermal resistance of 4.3 K/W (typical, LED only), a luminous intensity of 87.5 cd, and a colour chromaticity of 0.33 (Cx) and 0.34 (Cy). Both models deliver a beam angle of 120 degrees at 50% luminous intensity.
