These high intensity white LED lamps are based on InGaN material technology. A blue LED die is coated by phosphor to produce white. The typical resulting color is described by the coordinates x = 0.31, y = 0.31 using the 1931 CIE Chromaticity Diagram. These LED lamps have well defined spatial radiation pattern and high luminous white emission. The viewing angle options are 15°, 23°, and 30°. They can be used with standoff or non-standoff leads. Compared to incandescent bulbs and other alternative white light sources, they offer reduced power consumption, higher reliability, and increased optical/mechanical design flexibility.
