Osram say their new Synios P2720 CR enables especially compact rear fog lamp designs in this current era’s drive for smaller and smaller lamps with more and more compact packaging. The new LED offers outstanding performance despite its small dimensions.
One of the main issues with monochromatic LEDs for rear fog applications is the enormous intensity droop, up to about 50 percent, in operating temperatures above 60 °C. Until now, rear lamp manufacturers had to compensate for this by increasing the number of LEDs, which also increased the space requirements. The conversion-based Synios P2720 CR dramatically cuts this output degradation down to only around 10 percent. That unlocks better performance and lower cost by dint of fewer LEDs.
Fewer LEDs also means the heat sink can be smaller, saving additional space and weight (and cost). Manufacturers can choose between two different chip sizes: 0.5 or 1 mm2, as best suited to the application at hand. Either way, the space-saving package dimensions of 2.0 × 2.7 × 0.6 mm are the same.
