High-Brightness Device Provides Independent Control Of Red, Green, And Blue Chips
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 3.5 mm by 2.8 mm by 1.45 mm PLCC-6 surface-mount package, the Vishay Semiconductors 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 suited 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 uses high-brightness AllnGaP and InGaN technologies to deliver luminous intensity to 1800 mcd at 20 mA and features a ±60 degree angle of half intensity.
Providing high reliability, the Automotive Grade VLMRGB6112.. offers a temperature range from -40degC to +110degC, excellent corrosion robustness and sulphur resistance (H2S), and a UV-stable, diffused silicone casting compound for a long lifetime.
