features high brightness material alingap 630 mm red viewing angles: major axis 100 minor axis 50 well defined spatial radiation pattern superior resistance to moisture applications commercial outdoor advertising full color signs description these precision optical performance oval leds are specifically designed for full color/video and passen- ger information signs. the oval shaped radiation pat- tern (50 x 100 ) and high luminous intensity ensure that these devices are excellent for wide field of view outdoor applications where a wide viewing angle and readability in sunlight are essential. these lamps have very smooth, matched radiation patterns ensur- ing consistent color mixing in full color applications, message uniformity across the viewing angle of the sign. high efficiency led materials are used in these lamps: aluminum indium gallium phosphide (alingap) for red color. the higher performance alingap ii is used. each lamp is made with an advanced optical grade epoxy offering superior high temperature and high moisture resistance in outdoor applications. the package epoxy contains both uv-a and uv-b inhibitors to reduce the effects of long term exposure to direct sunlight. designers can select parallel (where the axis of the leads is parallel to the wide axis of the oval radiation pattern) or perpendicular orientation. both of the lamps are red diffused-tinted. hlmp-ld16/hlmp-md16 4 mm precision optical performance red ov al leds data sheet
