Abstract

The invention provides an electrode-less lamp and a lighting tube thereof. The lighting tube comprises a mushroom bulb body and two side wall bodies, wherein the mushroom bulb body is connected with the two side wall bodies and is U-shaped; a bridging part is arranged between the two side wall bodies; and a coil is enwound on the bridging part. The electrode-less lamp has an impact outline structure, has a volume of the whole body, and is convenient to be used for construction, maintenance and home lighting.

Description

technical field [0001] The invention relates to the technical field of lighting devices, in particular to an electrodeless lamp and a lamp tube thereof. Background technique [0002] Inductively coupled plasma (ICP) has been known for more than a hundred years. This type of plasma is widely used in various processing aspects of plasma due to its high efficiency and uniformity - plasma etching, plasma surface deposition and crystal growth, etc. Recently, research on low-pressure inductively coupled plasmas tends to develop such devices in the field of lighting. All kinds of induction electrodeless light sources made based on its principle are gradually replacing all kinds of traditional light sources due to their long life, good consistency and high light efficiency. [0003] This type of plasma is a discharge formed by coupling a certain amount of energy excited by an external electromagnetic field, but there are significant differences in the position, shape and operating...
