LED Assembly Delivers Wide Color Range

With four 1W LED die on a single assembly for solid state lighting applications, the OV4Z Optimal IV Star Series star-shaped red/green/blue/amber LED assemblies are available in mono-color or RGBA packages. They feature a recessed die design that houses four LED chips under a 5-mm, optical-grade water-clear lens. The assemblies achieve a thermal resistance of less than 2° C/W from junction to heat sink. With colors of blue (455 nm to 460 nm), green (530 nm to 535 nm), red (620 nm to 630nm), amber (585 nm to 595 nm), and daylight white, typical forward voltage at 350 mA ranges from 2.5V to 3.9V for the RGBA devices and 8.6V to 13.1V for the mono-color assemblies. Luminous flux at 350 mA ranges from 5 lm to 36 lm and 29 lm to 162 lm depending on LED color. Viewing angle for both the RGBA and mono-color assemblies is 60°. Additionally, maximum allowable junction temperature is +130°C with an operating temperature range of -50°C to +100°C. Typical pricing for the Optimal IV Star Series ranges from $7.78 to $10.37 each/1,000, depending on color. OPTEK TECHNOLOGY INC., Carrollton, TX. (972) 323-2200.
