A versatile four-lead, RGB solid-state LED light source, the LC503NPP-20H-A3, is now available from Marktech Optoelectronics. Manufactured by Cotco, the RGB LED features a 20 degree viewing angle in a 5mm round lensed package. The combination of high light output, low power consumption, and high-reliability materials means that the LEDs are a great choice for colour changing applications, says the company.
The LED also features a close chip density and brightness for 'excellent' colour mixing. Its 4-pin package allows for individual control of each red, green and blue chip. This creates an opportunity for users to produce a complete colour spectrum to better achieve specific and more uniform lighting architecture. By allowing individual control of each chip along with the LEDs improved efficiencies and output, designers can save additional power usage on their total lighting system to decrease overall operating costs.
Colour-changing light applications use RGB LEDs to create light fixtures that can be tuned to a specific colour. These multi-coloured fixtures have a number of uses including event lighting, architectural accent lighting, mood lighting, and artistic installations. Additional applications for this RGB LED include multi-colour backlighting, light pipes, full colour signboards, decorative lighting, general indicators, and amusement equipment, says the company.
