 The LED had an extremely low thermal resistance. |
TT electronics OPTEK Technology has developed a star-shaped red/green/blue/amber LED assembly with exceptional thermal performance and feature:
- Mono-color or RGBA packages.
- Recessed die design that houses four LED chips under a 5mm opticalgrade water clear lens.
- Extremely low thermal resistance of <2°C/W from junction to heatsink.
- Emitted colors of blue (455 - 460nm), green (530 - 535nm), red (620 - 630nm), amber (585 - 595nm), and daylight white.
- 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.
- Luminous flux at 350mA ranges from 5 lm to 36 lm and 29lm to 162 lm, depending on LED color.
- Viewing angle of 60°.
- Maximum allowable junction temperature is 130°C, with an operating temperature range of -50°C to +100°C.
