Abstract: An inner coupling tubular type electrodeless lamp comprises a glass bulb, an amalgam, and a power coupler. The glass bulb includes an external portion and an inner portion. A gas discharging cavity that is annularly airtight is defined by an envelopment of the external portion and the inner portion. A coupling cavity is defined in the inner portion. The power coupler includes a radiating post, a ferrite core, and a winding sequentially situating from an interior to an exterior thereof. The power coupler is disposed in the coupling cavity. Two ends of the coupling cavity are intercommunicated with each other as well as the exterior. The external portion of the glass bulb adopts the elongated tube. Wherein, a length of the ferrite core of the power coupler is not smaller than a half length of the coupling cavity. A length of the winding is measured from one-fifth to four-fifth of the length of the coupling cavity to evenly distribute an electromagnetic field.

Abstract: An electrodeless lamp street lighting fixture comprises a housing, an electronic ballast, and a light emitter that comprises a light bulb, a light reflecting cover, and a transparent cover fixed together. The light emitter and the electronic ballast could be pivotally connected to the housing. An external surface of the housing is served as a radiating plane of the electronic ballast. Therefore, the present invention needs no tool for dismantlement, the radiating effect of the electronic ballast is satisfactory, and the installment is convenient.

Abstract: An inner coupling electrodeless lamp comprises a glass bulb and a power coupler. A cold end of the glass bulb is provided with an amalgam. The glass bulb includes an external portion and an inner portion. A gas discharging cavity that is annularly airtight is defined by the envelopment of the external portion and the inner portion. The gas discharging cavity is full of inert gas. A coupling cavity is defined in the inner portion. The power coupler includes a radiating post, a ferrite core, and a winding sequentially situating from an interior to an exterior thereof. The power coupler is disposed in the coupling cavity. At least one diffuse reflection layer that is made of a material falling in a 250˜2000 nm spectrum scope and containing a high diffuse reflection rate larger than 30% is disposed between an inner wall of the inner portion and an external surface of the coupler.
