TT electronics Optek Technology has introduced a full colour SMT LED package, designed specifically for high current drive. The OVSPRGBCR4 device offers high luminance, a long operating lifespan and wide viewing angle. Each colour can be independently controlled for high output from each individual chip, as well as programmed for colour mixing to achieve all the colours of the rainbow plus white.

According to Richard Saffa, vice president of Optek Technology's visible LED business unit, the specifications of the device make it suitable for specialised applications.

"The OVSPRGBCR4 LED package was designed with a high flux output, low thermal resistance and ultra-low profile," said Saffa. "The energy-efficient design, along with the RGB colour-capabilities, high CRI rating and full 130° viewing angle, make it ideal for a variety of lighting applications, including entertainment lighting, "mood" lighting in automotive, airplane and lift cabins, retail product illumination, architectural accents and conventional lighting."

Additional applications for the RGB LED package include automotive interior and exterior lighting, architectural indoor and outdoor lighting, LED backlighting and general illumination.

The RGB LED package is composed of a red, green and blue LED with water clear lenses mounted on the top of the device. Typical luminous flux for the red, green and blue LEDs is 21 lumens, 32 lumens and 7.5 lumens, with a typical on-axis intensity of 7cd, 11cd and 2.8cd, respectively.

DC forward current is 250mA per colour, with peak pulsed forward current of 500mA plus a thermal resistance of 20K/W. Maximum rated junction temperature is 125°C and the operating temperature range is -40°C to 100°C. Optek also offers optional optics to suit specific applications. The OVSPRGBCR4 LED package measures 6-by-6-by-1.5mm.

Typical pricing for the OVSPRGBCR4 full-colour power LED package starts at Rs.169.08 ($4) each in quantities of 10,000. Production quantity lead times, if stock is not available, are from 7 to 9 weeks.
