Osram Opto Semiconductors presents the new multi-chip-LEDs with a broad bright blue color range. This gives lighting designers a free choice of colors for the interior lighting in vehicles. Color design now covers cluster lighting to an increasing extent, notably in combined instruments such as speedometers and rev counters, in displays, as backlighting for switches and for ambient lighting. Rutronik distributes the MultiLED as of now. The main feature of the new MultiLED in the standard 3.3 x 3.0 x 1.8mm SMT package is a very broad blue color range with a wavelength of up to 447nm and high brightness, which allows the production of deep saturated blue tones. This is thanks to the use of three LED chips in red, green and blue (RGB). At 370mcd the blue is very bright.
This brightness is a huge advantage as the human eye perceives the color blue darker than it really is and the new MultiLED can offset this darker perception. Other properties of the MultiLED are an integrated ESD protective diode (electrostatic discharge), an improved corrosion resistance and a long market availability, which makes them ideal for use in automobiles.
