    摘要: A method and system to supply current to a high pressure lamp is provided, the method and system comprising an alternating lamp current waveform with a half cycle mean amplitude I1 and a half cycle time duration T, a current pulse waveform including at least one current pulse with a half cycle mean amplitude I2 and at least one current pulse occurring after the trailing edge of a half cycle of the alternating lamp current, the pulse having a half cycle duration of Tp. These waveforms are combined to generate a current waveform including a current pulse waveform, the current pulse waveform starting after a time delay Td from the trailing edge of a half cycle of the alternating lamp current waveform, the time duration Tp of the at least one current pulse lasting less than the remaining time before the leading edge of the second half cycle of the alternating lamp current waveform. The combined current waveform supplies current to a high pressure lamp and produces a cone shaped tip protrusion which reduces lamp flicker.

    摘要: A high pressure discharge lamp with a thermally improved anode, as well as a method of making such a lamp, are disclosed. The lamp includes a refractory arc tube with a hermetically sealed arc chamber, a fill in the arc chamber for facilitating light generation, and an anode and a cathode extending into the hermetically sealed arc chamber and being spaced apart from each other. The anode comprises a shank of refractory metal, a cylindrically shaped refractory metal sleeve on a portion of the shank, and an end proximally facing the cathode. The anode end comprises a substantially solid mass of refractory metal, and is integrally joined to both the shank and the metal sleeve to facilitate heat flow from the anode end to the shank and sleeve. The anode end preferably is generally shaped as a hemisphere facing the cathode. The refractory metal sleeve is preferably one or more layers of a helically wound refractory metal wire having an outer diameter more than twice a diameter of the shank.

    摘要: A lighting apparatus includes a bilaterally symmetrical light engine comprising first and second light emitting diode (LED) devices or planar LED device arrays facing opposite directions, and an envelope including phosphor spaced apart from and surrounding the bilaterally symmetrical light engine. The phosphor is effective to convert light emitted by the light engine to emission light. The bilaterally symmetrical light engine may be configured to emit light having a bilaterally symmetrical intensity distribution that is uniform except at emission angles within 10° of the symmetry plane of the bilaterally symmetrical light engine. Each of the first and second LED devices or planar LED device arrays may comprise at least one hemispherically emitting LED device including an LED chip and an encapsulant encapsulating the LED chip and shaped to refract light emitted by the LED chip into a uniform distribution over a hemispherical solid angle.

    摘要: A low watt ceramic metal halide lamp has a body with a discharge chamber disposed therein. First and second hollow legs extend from the discharge chamber and received first and second electrode assemblies, respectively, therethrough with first ends of the electrode assemblies disposed in spaced relation in the discharge chamber. Use of thin legs limits heat flux from the discharge chamber. Preferably, thin legs are defined by a load dissipation factor of the ceramic part being less than 0.065 mm2/watt. In addition, thermal conductance along the leg is controlled via a load dissipation factor of the molybdenum mandrel portion of the electrode assembly being maintained less than 0.0008 mm2/watt.
