  • Patent number: 5800050
    Abstract: Downlight and downlight wall wash reflectors particularly useful with compact fluorescent lamps and other large-area light sources, the reflector optics of the invention maximize the efficiency of the luminaire while providing brightness control and avoidance of high angle glare or "flash". Downlight reflectors according to the invention provide a truly uniform illuminance distribution across the illuminated area when applied in a rectangular grid with maximum use of available light by providing an upper amplifying reflector section which reflects normally underutilized light to a lower distribution reflector section which radiates a large percentage of generated light effectively from the bottom of the light source, thus reducing the apparent size of the light source and increasing optical control. The lower reflector section reflects light only into zones where the light is needed and avoids high angle zones, most of the light being reflected into zones from 35.degree. to 45.degree.

  • Patent number: 5739639
    Abstract: Circuitry for operating an array of light emitting diodes such as in an emergency exit sign in a non-emergency AC mode while concurrently charging and maintaining the charge of a low-voltage battery used to drive the array in an emergency mode, the circuitry also allows operation of the same LED array in the emergency mode from the low-voltage battery. The advantages of the invention are realized in part through provision within the circuitry of a boost converter wherein the LED array and the battery are connected across the output of the usual boost circuit output capacitor, thereby allowing connection of the array and the battery in series to simplify operation from line power and to allow the same current limited source to operate the array and simultaneously charge the battery through the same current path. The functions so provided can be embodied in a form which allows all circuitry components including the battery to be mounted on a single, compact substrate such as a printed circuit board.

  • Patent number: 5658209
    Abstract: Golf club heads each having a specifically contoured back side shaped to provide an optimal three-dimensional mass distribution, the invention preferably takes the form of "oversize" iron club heads having an unusually large "sweet spot" while retaining traditional iron head weights. The optimally distributed mass of each head is provided over the entire back side of the head with the back side contour interacting with face-stiffening ribs located on the top and toe of the head to yield performance advantages. The versatility found in the contouring of the back side of each head to yield optimal mass distribution allows the hitting area of each club face in a set of clubs to increase incrementally as the loft of each iron decreases, thereby resulting in a more uniform "sight picture" between clubs as viewed by the player.
