LED provides independent control of red, green and blue chips for wide colour range

Vishay Intertechnology has introduced a new high-brightness, tricolour LED optimised for interior automotive lighting, RGB displays, and backlighting. Featuring separate red, green, and blue LED chips inside the compact 3.5mm x 2.8mm x 1.45mm PLCC-6 surface-mount package, the VLMRGB6112 enables 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 colour range, the LED is ideal for custom ‘welcome illumination’ in next-generation automobiles; large-format, full-colour message and video display boards; backlighting in consumer devices and appliances such as PDAs, televisions, ovens, and microwaves; and a wide range of accent and decorative lighting. For these applications, the device utilises high-brightness AllnGaP and InGaN technologies to deliver luminous intensity to 1800mcd at 20mA and features a ±60 degree angle of half intensity. Providing high reliability, the automotive grade device offers a wide temperature range from -40C to +110C, excellent corrosion robustness and sulfur resistance (H2S), and a UV-stable, diffused silicone casting compound for a long lifetime. The LED is AEC-Q101-qualified, offers a moisture sensitivity level of two, and withstands ESD voltages up to 2kV in accordance with JESD22-A114-B. Compatible with IR reflow soldering, the device is RoHS-compliant, halogen-free, and Vishay Green.
