LITE-ON TECHNOLOGY CORPORATION Property of Lite-On Only LTL2P3SEK LTL2R3SEK LTL2P3SYK LTL2R3SYK Technical Data Ultra Bright LED Lamp for Traffic Sign Red 22o Red 30o Amber 22o Amber 30o * Lower system cost. * Higher luminous efficiency than incandescent lamp. * Fewer LED are required due to the TS AlInGaP technology. * High luminous intensity output. * Low power consumption. * High efficiency. * Versatile mounting on PCB or panel. * I.C. Compatible / low current requirements. * Popular T-1 4 diameter 5 mm . The source color light emitting diode dice of these devices is made of AlInGaP on a transparent substrate TS . The water clear epoxy lens on these devices create viewing angles of 22 and 30 degrees that match international specifications for traffic sign utilization. These LED lamps provide superior endurance against moisture and high temperatures thus are reliable for outdoor environment use. With a lower power consumption than traditional incandescent lamps, these devices yield lower system cost. * Traffic signals. * Versatile warning signals. * Outdoor traffic display panels.
