摘要： A method and system of modifying one feature of a high-pressure lamp without significantly affecting the other features, the features including the luminosity, the color rendering index, the color temperature, or the deviation from the black body locus (DUV). An arc discharge is initiated within the arc tube with a ballast imposing an alternating current waveform on the electrodes. In this way, the electrodes change from positive to negative in each cycle of operation. The waveform of each cycle is modified through the ballast to energize one electrode as positive or negative for a longer time than the other electrode, thereby altering the temperature distribution within the arc tube by changing the cold spot and hot spot temperatures in a lamp which has modifiable emission features.

摘要： This invention relates to dimmable metal halide lamps using ceramic arc tubes for the application of energy saving, mood control, and constant light output over the life of the lamp. Under dimmed conditions, as low as 50% of rated wattage, the color temperature (CCT) can remain substantially the same and be perceived by the viewer as a constant color light source. Furthermore, the invention improves the color rendering index (CRI) and the efficacy of the lamp under dimmed operation. Such improvements are provided by placing a metal shield on an end of the arc tube, whereby the emissivity of the shield is lower than the emissivity of the ceramic in the arc tube, whereby cold spot temperature in the lamp is increased, even under dimmed conditions.

摘要： A lighting system includes a high intensity discharge metal halide lamp having an arc discharge chamber with electrodes at each end and containing a fill of mercury, rare gas and metal halides, and a ballast circuit configured to supply pulsed electrical power to the lamp. The ballast circuit includes a controller configured to adjust the pulsed lamp power between a first relatively high power level at a relatively high duty cycle and a second relatively low power level at a relatively low duty cycle. The controller may be configured to adjust the pulsed lamp power between 90% duty cycle at rated lamp power and 10% duty cycle at 30% of the rated lamp power. The duty cycle of the pulsed lamp power may be controlled to maintain a substantially constant correlated color temperature (CCT) as the power level is adjusted.
