  • Patent number: 9642207
    Abstract: A light emitting apparatus includes a first light emitting device configured to emit light having a first chromaticity point that falls within a region on a 1931 CIE Chromaticity Diagram defined by points having coordinates (0.32, 0.40), (0.36, 0.48), (0.43, 0.45), (0.42, 0.42), (0.36, 0.38), and at least two second light emitting devices, each of the at least two second light emitting devices emits light having a respective second chromaticity points that that have ccx values greater than 0.4077 and ccy values less than 0.3944 on the 1931 CIE Chromaticity Diagram. A combined light emitted by the first light emitting device and the at least two second light emitting devices has a third chromaticity point that falls within a 7-step MacAdam ellipse around a point on the black body locus having a correlated color temperature between 2700K and 6500K. The third chromaticity may shift to a more reddish chromaticity when power supplied to the light emitting devices is decreased.

    Abstract: A light emitting apparatus includes a first light emitting device configured to emit light having a first chromaticity point that falls within a region on a 1931 CIE Chromaticity Diagram defined by points having coordinates (0.32, 0.40), (0.36, 0.48), (0.43, 0.45). (0.42, 0.42), (0.36, 0.38), and at least two second light emitting devices, each of the at least two second light emitting devices emits light having a respective second chromaticity points that that have ccx values greater than 0.4077 and ccy values less than 0.3944 on the 1931 CIE Chromaticity Diagram.

  • Patent number: 8698388
    Abstract: A lighting module includes a plurality of solid state light emitting components configured to collectively emit light having a desired white point and a color rendering index (CRI) of greater than about 90. The module further includes at least one additional solid state light emitting component configured to individually emit light having a white point substantially similar to the desired white point. The at least one additional light emitting component may increase a lumen output of the lighting module without substantially altering the desired white point of the light collectively emitted by the plurality of light emitting components.

  • Patent number: 4268987
    Abstract: An elongated tubular barrel is provided having front and rear end portions. The rear end portion of the barrel is externally threaded and removably threadedly engaged in a forwardly opening threaded counterbore formed in an elongated breech body having a bore formed longitudinally therethrough with its forward end opening into the aforementioned counterbore. A firing pin is longitudinally received and reciprocal in the bore formed through the breech body and the rear end of the breech body includes a diametrically enlarged endwise outwardly opening counterbore. An abutment is mounted on the rear end of the firing pin and is reciprocal in the last mentioned counterbore and projects at least slightly outwardly therefrom.

  • Patent number: 4083138
    Abstract: An elongated tubular barrel is provided having front and rear end portions. The rear end portion of the barrel includes chamber structure for removably chambering a cartridge in the barrel. Firing pin structure for firing a cartridge chambered in the barrel is provided and is shiftable between ready and firing positions. A palm grip is supported from the rear end portion of the barrel of a size to be substantially enclosed within one hand with the forward end of the barrel of the weapon projecting forwardly and outwardly between adjacent fingers of the hand. The forward end of the barrel tapers in wall thickness to a circumferentially unobstructed thin wall portion at the forward terminal end of the barrel, whereby the forward terminal end may be thrust forwardly against a flesh target and at least partially penetrate the target substantially simultaneously with the firing of a cartridge chambered in the barrel.
