Abstract

The invention relates to a low-power electrode-less lamp and a lamp tube thereof. The lamp tube comprises a lamp tube main body and a coil wound on the lamp tube main body. The lamp tube main body comprises a spherical shell, two side arms and a bridge arm, wherein the two side arms are arranged on a same hemisphere of the spherical shell; one end of the two side arms connected to the spherical shell is communicated with the spherical shell while the other end of the two side arms is enclosed; the two ends of the bridge arm are respectively connected to the two side arms; the bridge arm is respectively connected to the two side arms; and the coil is divided into three sections which are respectively directly wound on the bridge arm and the two side arms. The low-power electrode-less lamp and the lamp tube thereof of the invention occupy less space, are convenient to mount, have stable property, and can be widely applied in the fields of industry search lighting, industry construction,maintenance, civil lighting, and the like.

Description

technical field [0001] The invention relates to the field of lighting sources, in particular to a low-power electrodeless lamp and a lamp tube thereof. Background technique [0002] The electrodeless lamp consists of three parts: excitation power supply, power coupler and bulb. The excitation power supply generates an electric frequency current above 150KHz and sends it to the power coupler. When the high frequency current passes through the power coupler, a high frequency electromagnetic field is generated. The changing magnetic field generates an electric field perpendicular to the magnetic field, so that the electrons in the discharge space inside the bulb are accelerated by the electric field. When the energy reaches a certain value, the electrons collide with the gas molecules in the container, and the gas in the bulb is avalanche ionized to form plasma. When the plasma excited atoms return to the ground state, they emit ultraviolet light, and the ultraviolet light exci...
