    摘要: The color temperature of light emitted by a luminaire having a hollow prismatic light guide is varied to counteract aesthetically undesirable reddening gradient of the emitted light. Reddening is caused by the light guide's dielectric material, which absorbs blue light rays such that proportionately more red than blue rays are guided to the light guide's far end than to points near the guide's light input end. Flare light rays which escape through the light guide near its light input end are color filtered and reflected back into the light guide. The filter color lies within a CIE-1931 chromaticity diagram {4800° Kelvin; 570 nm; 600 nm} color gamut triangle. Color filtering absorbs blue flare rays as a function of distance along the guide, imparting a near-end reddening gradient to the emitted light in inverse proportion to the far-end reddening gradient, giving the emitted light a constant apparent color, independent of distance along the guide.

    摘要: Apparatus for monitoring and controlling the operation of one or more high intensity discharge (HID) lamps. An electronic HID lamp power supply is electrically connected to a power source and to the HID lamps. For each lamp, one or more sensors produce one or more output signals respectively representative of one or more parameters (such as light intensity, color temperature, power consumption, temperature, arc voltage, etc.) which respectively define one or more operational characteristics of the lamps. A programmable controller receives the sensors' output signals and programmatically responds by, for example, outputting to the power supply control signals for controlling operation of the lamps to cause a selected variation in a selected one or more of the sensed parameters, and/or by periodically logging information characteristic of an operational state of one or more of the lamps or the power supply at a selected time or times, and/or by producing diagnostic information characteristic of an operational state of one or more of said lamps or said power supply.
