Osram has introduced new rear LED fog light technology that that offers improved visibility in poor weather conditions. The Synios P2720 CR also provides many benefits to manufacturers enabling more compact rear fog lamp designs.

Osram says the trend for both headlamps and rear combination lamps is towards more compact and efficient designs. While the installation space required decreases, the design options available to manufacturers greatly increases. The new LED Synios P2720 CR LED addresses this trend of miniaturisation as in spite of its small dimensions, it offers outstanding performance values in applications.

One of the main issues with monochromatic LEDs for rear fog applications is the enormous loss of brightness (often called degradation) of about 50% in operating temperatures of 60° - 70° C. Until now, rear lamp manufacturers had to compensate for this physically induced gap by increasing the number of LEDs, which also increased the space requirements. Now the new, conversion-based Synios P2720 CR, can dramatically reduce this loss of brightness to only around 10%. Customers enjoy better performance, while manufacturers benefit because considerably fewer individual LEDs are required.

Fewer LEDs means the required heat sink can be very compact, saving additional space and weight. Rear lamp manufacturers can choose between two different chip sizes (0.5 mm² or 1 mm²), depending on the design of the application. The space-saving package dimensions of just 2.0 mm x 2.7 mm x 0.6 mm remain the same.
