摘要： An electrodeless lamp includes a bulbous lamp envelope enclosing an inert gas and a vaporizable metal fill, the lamp envelope having a reentrant cavity; an electromagnetic coupler positioned within the reentrant cavity; and a cold spot structure configured for low temperature, low duty cycle operation and for room temperature, 100% duty cycle operation. In some embodiments, the cold spot structure includes a dimple in the lamp envelope, the dimple having a thinned sidewall. In further embodiments, a shield is positioned near the dimple to control cold spot temperature. In additional embodiments, the cold spot structure includes a heat sink attached to the exhaust tube of the lamp envelope and thermally isolated from the lamp base.

摘要： An electrodeless lamp includes a bulbous lamp envelope enclosing an inert gas and a vaporizable metal fill, the lamp envelope having a reentrant cavity and an envelope bottom, an electromagnetic coupler positioned within the reentrant cavity, and a thermal shield positioned in proximity to the envelope bottom and configured to increase the temperature of the envelope bottom. By increasing the temperature of the envelope bottom, a cold spot is prevented. As a result, light output at low temperatures is comparable to light output at room temperature.
摘要翻译：无电极灯包括包围惰性气体的球状灯管和可汽化的金属填充物，灯壳具有可折入的空腔和封套底部，位于折入腔内的电磁耦合器和位于封套底部附近的热屏蔽并且被配置为增加信封底部的温度。通过增加信封底部的温度，可以防止冷点。结果，低温下的光输出与室温下的光输出相当。
