OPTEK OV4Z IVIntegrating 4 1-W LED dies into a single assembly for solid state lighting applications, OPTEK Technology’s OV4Z Optimal IV Star Series star-shaped LED assemblies present a thermal resistance of <2°C/W from junction to heatsink. The devices offer emitted colors of blue (455 nm to 460 nm), green (530 nm to 535 nm), red (620 nm to 630 nm), amber (585 nm to 595 nm), and daylight white. Typical forward voltage at 350 mA ranges from 2.5 V to 3.9 V for the RGBA devices and 8.6 V to 13.1 V for the mono-color assemblies, while luminous flux at 350 mA ranges from 5 lm to 36 lm and 29 lm to 162 lm, depending on LED color. The units exhibit a viewing angle of 60°, max. allowable junction temperature of 130°C, and an operating temperature range from -50°C to 100°C. From $7.78 to $10.37 in 1,000 quantities.
