摘要： A lens mounted to a light emitting diode package internally redirects light within the lens so that a majority of light is emitted from the lens approximately perpendicular to a package axis of the light emitting diode package. In one embodiment, the light emitted by the light emitting diode package is refracted by a sawtooth portion of the lens and reflected by a total internal reflection portion of the lens.

摘要： A luminaire comprises a relatively thin and flat light-emitting panel (1) having a light-emitting window (2) and, opposite said light-emitting window, a rear wall (3) with opposed edge surfaces (4, 14). At least one of the edge surfaces (4) is light transmitting and associated with a plurality of light sources (5, 5', 5", ...). Light originating from the light sources (5, 5', 5", ...) is spread in the panel (1). The invention is characterized in that a plurality of deformities (7, 7', 7", ...; 8, 8', ...) is provided in the panel (1) for extracting light from the panel (1) via the light emission window (2). The deformities (7, 7', 7", ...; 8, 8', ...) are clustered so as to form at least one light symbol (27; 28). The configuration of the clusters (17; 18) of deformities (7, 7', 7", ...; 8, 8', ...) corresponds to the shape of the light symbol (27; 28). Preferably, the luminaire has a first and a second light-transmitting edge surface, with respectively, a first and a second plurality of light sources being associated with said surfaces. A first cluster of deformities only couples light from the first light source out of the panel, thereby forming a first light symbol, while a second cluster of deformities only couples light from the second light source out of the panel, thereby forming a second light symbol, independently of the formation of the first light symbol. The luminaire according to the invention provides independent lighting and coloring possibilities of light symbols in a single-panel luminaire.

摘要： The present invention describes a method and luminaire for drivi ng an array of LEDS with at least one LED in each of a plurality of colors in a luminaire. This method controls the light output and color of the LEDs by measuring color coordinates for each LED light source for different temperatures, storing the expressions of the color coordinates as a function of the temperatures, deriving equations for the color coordinates as a function of temperature, calculating the color coordinates and lumen output fractions on-line, and controlling the light output and color of said LEDs based upon the calculated color coordinates and lumen output fractions.

摘要： Circuitry is provided for powering a gaseous discharge lamp which has a range of possible parasitic loading capacitance's associated with it. The circuitry includes a source of ignition pulses, preferably a reactive one, which stores sufficient energy to charge the highest value of parasitic loading capacitance in the range to at least the minimum ignition voltage of the lamp. A voltage clamping element limits the peak voltage of the ignition pulses, even at the lowest value of parasitic loading capacitance in the range, to a maximum permissible voltage that may be applied to the lamp. The source and the voltage clamping element cooperate to automatically provide high-energy ignition pulses to the lamp, with peak voltages well within permissible limits, over the entire range of parasitic loading capacitance's.
