LED allows independent control of R, G and B chips
Vishay has introduced a new tricolour LED that provides luminous intensity to 2800 mcd at 20 mA 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 3.5 mm by 2.8 mm by 1.4 mm PLCC-6 surface-mount package, the Automotive Grade VLMRGB6122 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 suitable 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 uses the latest AllnGaP and InGaN technologies to deliver 70 percent higher brightness than previous-generation solutions in a package with a 22 percent lower profile than competing products, according to Vishay.
The VLMRGB6122 offers a wide temperature range from -40 °C to +110 °C, which is 25 °C higher than standard solutions, and Class B1 corrosion robustness. The LED is AEC-Q102 qualified, offers a Moisture Sensitivity Level (MSL) of 3, and withstands ESD voltages up to 2 kV for red and 8 kV 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.
