  • Led luminaire with light control means
    Publication number: 20020006040
    Abstract: An LED luminaire is formed such that a plurality of LED chips are disposed three-dimensionally on an MID (molded interconnection device) substrate in a rectangular plate shape, by mounting three LED chips on bottom face of respective dents provided lengthwise and crosswise in one surface of the MID substrate, the LED chips including at least two types diffferent in luminous color, desirably three types of red, blue and green colors. Any optional light distribution characteristic is made thereby easily obtainable depending on a configuration of the substrate, luminaire module can be thinned, and such delicate color difference as white color and day-light color of luminescent lamps is enabled by mixing the luminous colors of the respective LED chips.
