摘要： An electrodeless high intensity discharge lamp with a lamp fill material including gallium iodide has been found to be more efficient in generating light in general, and more efficient in generating blue light. The very small size of the lamp, in combination with the high intensity in a relatively narrow blue spectral range make the lamp particularly useful in supplying blue light to a fiber optic. The relative efficiency of the lamp increases its value. In combination, the lamp provides a useful, efficient source of blue light as an input source for optical fiber, and other systems for medical and other processes using blue light as a process element.

摘要： Techniques are disclosed for controlling the light output of a lamp, where lamp efficacy is estimated as a function of estimated lamp temperature and instantaneous input power, or as a function of estimated lamp temperature only. Whether efficacy is estimated as a function of temperature and power, or as a function of temperature only can depend on changes in the lamp operating scenario. The techniques estimate lamp temperature by tracking energy input to and losses from (losses such as radiation, conduction, emission) the lamp arc tube, and determine the corresponding instantaneous light producing ability. The techniques may further be implemented to deliver the appropriate power command to obtain a desired light output. The techniques can be applied towards a general control in which arbitrary or custom light output vs. time paths are produced, and may be implemented by a processor programmed or otherwise configured to execute the desired control scheme.

摘要： Systems and methods are disclosed that allow a lighting system to self-determine the relative positions of its different light sources. Direct light source to light source distances are measured and trilateration is used to locate each light source in three dimensional space. The relative position of each light source is provided with regard to the lighting system itself and does not need to refer to a GPS system or to the position or orientation of the installation. The self-determining system allows lighting systems to be quickly installed and later commissioned using the positioning information provided by the lighting system itself.

摘要： Metal halide lighting with good color during dimming may be obtained. An appropriate balance of commonly used metal halides (NaI, DyI3, CeI3, CaI2, TlI) is dosed in the lamp. No mercury is used. A higher than typical xenon fill pressure from 50 to 500 Kilopascals may be used to help control thermal properties and voltage. If necessary, modulation of the power at acoustic resonance frequencies may be used to straighten and center the arc. Efficient and pleasant white output is obtained. As the power is reduced, the chromaticity either (1) remains fairly constant or (2) drifts acceptably towards warm pinkish colors. Large factors of attenuation in output can be realized. The lumen output was reduced by at least a factor of twenty in one sample as the power was dimmed from 70 to 20 watts.

摘要： A system for providing spatially and temporally smooth occupancy lighting includes a sensor and a controller. The sensor is configured to determine a precise location of the occupant. The controller determines a number of lighting fixtures that are relevant to the location of the occupant. The light output of the lighting fixtures is controlled by the controller using a function that varies the light output depending on the location of the occupant. The function can change the light output based upon a distance between the occupant and the one or more lighting fixtures. For example, the function can increase the light output as the occupant moves closer to a fixture, and likewise decrease the light output as the occupant moves away from a fixture. In another example, the function can maintain a target illuminance at a particular spot within the space or an overall illuminance for all lighting fixtures.

摘要： Techniques are disclosed for controlling object appearance while maintaining a lighting function without noticeable changes in illumination. The techniques may be implemented to illuminate a given target with a first light source so as to cause the target to have a first appearance, and to illuminate the target with a second light source so as to cause the target to have a second appearance different from the first appearance. The first and second light sources have a chromaticity within a common MacAdam ellipse. The MacAdam ellipse size may range, for example, from a 7-step ellipse (for relaxed constancy in chromaticity) to a 1-step ellipse (for high constancy in chromaticity). In some cases, one of the first or second light sources includes a spectral feature not included in the other light source, and an optical response property of the target reacts to changes in the spectral feature thereby causing appearance changes.

摘要： Techniques are disclosed that allow for the use of metal halide lamps in dimming applications, as well as other discharge lamps susceptible to dimming-induced chromaticity drift. Examination of such lamps reveals that some of the spectral changes that cause chromaticity drift during dimming are localized in narrow band regions of the spectrum, and lamp emission in these regions is enhanced (either increased or decreased) relative to the rest of the spectrum. Selective filtering of the enhanced emission caused by dimming can be used to reduce chromaticity shift. For instance, a filter deposited on and/or integrated into a lamp component (such as the arc tube, shroud, and/or outer jacket) operates to block transmission of those regions of the spectrum.

摘要： A method of detecting a leak in an outer jacket of a metal halide lamp having an arc tube inside the outer jacket and operated by a ballast, where the ballast monitors an electrical characteristic of the lamp during start and detects a leak in the outer jacket when the electrical characteristic deviates from that of a corresponding metal halide lamp whose outer jacket does not have a leak. The electrical characteristic is one of six markers, namely (1) V′(E) at a predetermined E, where V′(E) is a derivative of lamp voltage V as a function of cumulative energy E delivered to the ballast since ignition, (2) a value of E at which V′(E) reaches a maximum, (3) V at a predetermined E, (4) a local maximum of V′(E) up to a predetermined E, (5) a global maximum of V′(E), and (6) E required to achieve a predetermined V.

摘要： A method of operating a discharge lamp includes modulation of lamp power with a first longitudinal mode frequency to reduce segregation of the vapor phase species within the arc tube. The first longitudinal mode excitation frequency is determined by the acoustic response spectrum observed at an upper region of the arc tube when operated vertically. A frequency in an arc-straightening frequency range may also be added to the input power to straighten and center the arc.
