Integrating four 1-W LED die into a single assembly for solid state lighting applications, TT electronics OPTEK Technology has developed a star-shaped red/green/blue/amber LED assembly with exceptional thermal performance. Designated the OV4Z Optimal IV Star Series, the LEDs are offered in mono-color or RGBA packages and feature a recessed die design that houses four LED chips under a 5mm optical-grade water clear lens. The assemblies achieve an extremely low thermal resistance of <2°C/W from junction to heatsink.
"The combination of red, green, blue and amber high-brightness LEDs provides solid state lighting designers with an extensive number of color combinations," said Alan Bennett, vice president of sales for OPTEK Technology. "The star-shaped assembly results in a simplified mounting configuration, while the design of the part provides customers with optimal luminous intensity and transfer of heat generated due to increased current value."
The OV4Z Series devices are exceptionally bright and ideally suited for applications including large signage; interior, exterior and landscape architectural lighting; recreational areas such as pools, spas and boats; and specialty lighting including vending machines, display cases and stage lighting.
The Optimal IV Star Series assemblies feature emitted colors of blue (455 - 460nm), green (530 - 535nm), red (620 - 630nm), amber (585 - 595nm), and daylight white. Typical forward voltage at 350mA ranges from 2.5V to 3.9V for the RGBA devices, and 8.6V to 13.1V for the mono-color assemblies, while luminous flux at 350mA 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 degrees. Maximum allowable junction temperature is 130 °C, with an operating temperature range of -50 to +100°C.
The mono-color assembly is available with mounting pads, while the RGBA assembly is available with through-hole pins or mounting pads for surface mount electrical connections, along with six locating slots for mounting screws. The assemblies are 0.83 inches (21mm) in diameter on a 0.04 inch (1mm) thick star-shaped PC board.
