New LED from Osram Provides Optimal visibility Even in Dense Fog

Chances of an accident increase significantly when motorists have to deal with dense fog and poor visibility. Such a scenario can lead to rear-end collisions which can be fatal. Hence, it is very important to enhance visibility by using bright rear fog lights in poor weather conditions.

Osram’s new Synios P2720 CR is of great benefit to manufacturers of rear combination lamps, as they can use this component to conceptualize compact rear fog lamp designs. Currently, the trend is to use more compact and efficient headlights and rear combination. The availability of more compact components translates into the need for less space for installation and greater flexibility with regard to design options.

The new LED Synios P2720 CR LED aligns well with this trend of miniaturization. Though its dimensions are small, it offers impressive performance values in applications. One main complaint regarding the use of monochromatic LEDs for rear fog applications is the immense loss of brightness (which is known as degradation) of about 50 percent in operating temperatures of 60 deg – 70 deg C. Generally, rear lamp manufacturers compensated for this physically induced gap by correspondingly increasing the number of LEDs. This led to need for further space.

In the case of the new, conversion-based Synios P2720 CR, this loss of brightness is limited to only around 10 percent. Customers get the benefits of better performance, and manufacturers benefit they need significantly fewer individual LEDs making its use a win-win situation for both parties.

Fewer LEDs means the required heat sink can be very compact, thus leading to additional savings with regard to 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.
