RGB LED provides independent control of chips for wide colour range

Vishay Intertechnology, Inc. has introduced a new tricolour LED that provides luminous intensity to 2800mcd at 20mA for interior automotive lighting, RGB displays, and backlighting. Featuring separate anode and cathode connections for the red, green, and blue LED chips inside its compact 3.5mm x 2.8mm x 1.4mm PLCC-6 surface-mount package, the automotive grade VLMRGB6122.. allows individual control of each chip, making it possible to realise every colour within the colour room defined by the gamut triangle area inside the CIE 1931 colour space through colour mixing.

With its wide color range, the Vishay Semiconductors LED released is ideal for ambient lighting, switch illumination, status indicators, and dashboard signal and symbol illumination in automobiles; large-format, full-colour message and video display boards; backlighting in consumer devices, home appliances, medical instrumentation, and telecom equipment; and a wide range of accent and decorative lighting. For these applications, the device employs the latest high-brightness AllnGaP and InGaN technologies to deliver 70% higher brightness than previous-generation solutions in a package with a 22% lower profile than competing products.

Providing high reliability, the VLMRGB6122.. supplies a wide temperature range of -40C to +110C, which is 25C higher than standard solutions, and Class B1 corrosion resistance. The LED is AEC-Q102 qualified, providing a MSL of 3, and withstands ESD voltages of up to 2kV for red and 8kV for blue and green, in accordance with JESD22-A114-B. RoHS-compliant, halogen-free, and Vishay Green, the device is compatible with IR reflow soldering and categorised per reel for luminous intensity, colour, and forward voltage.
