data sheet lx636d7y, lx546t7y, lx636t6y mediavista tm high brightness led lamps t-1? (5mm) oval red, green, blue and amber description: cao mediavista tm high brightness led lamps are specially designed for outdoor signal and sign applications. its precise optical design produces a high bright light source and well defined spatial radiation patterns. the lens was m ade with an advanced optical grade epoxy to produce superior high temperature and high moisture resistant performance in outdoor environments. it also contains uv inhibitor s to reduce the effects of long term exposure to direct sunlight. these led lamps use a standard t 1? (5 mm) oval package and options of lens color can be water clea r, color diffused, tinted and transparent. the chips of thes e leds are applied to the most up-to-date material technol ogy to produce the most efficient light output and highest junction temperature limit, which enable it to operate under bright sunlight and other high temperature environment. features: standard t-1? package precise optical performance lens options: - color diffused - tinted and transparent - water clear superior performance in outdoor environment - uv resistant epoxy - superior resistance to moisture outstanding led material efficiency - high luminous output - low electrical power consumption choice of standoffs : with or without view angles: 70 o /40 o or 70 o /30 o parallel colors: - red 625 nm - green 525 nm - blue 470 nm - amber 592 nm choice of packaging options: - bulk - ammo pack - tape and reel applications: outdoor message boards dynamic message signs commercial message centers caution: led lamps are esd sensitive electronic devices. pl ease observe appropriate precautions during handlin g and processing. refer to cao application notes for additional details.
