Embodiment Construction

[0021] see figure 1 , a high-frequency electrodeless lamp design based on microchannel heat pipes. It includes a high-frequency generator 1, an electromagnetic coupler 2, a heat pipe 3, a foam body 4, and cooling fins 5. The electromagnetic coupler 2 is nested on the upper end of the heat pipe 3 and placed in the concave cavity of the bubble body 4. The lower end of the heat pipe is sealed and bonded to the heat dissipation fin 5. The holes are fixed on the fins 5 .

[0022] see figure 2 The magnetic core of the electromagnetic coupler 2 is a magnetic tube 24 made of high-frequency ferrite material, the induction coil 23 is directly wound on the magnetic core 24 , and the lead wire is electrically connected to the high-frequency generator 1 . A circle of copper gasket 22 is welded in the upper part of the heat pipe to support the coupler 2, and the electromagnetic coupler magnetic core 24 is nested and in close contact with the upper end of the heat pipe 3, which is benefi...

Abstract

The invention discloses a high-frequency electrodeless lamp based on a micro-channel heat pipe. The high-frequency electrodeless lamp comprises a high frequency generator, an electromagnetic coupler, a heat pipe, a foam body, a heat dissipation fin and a foam body pedestal. A conventional copper tube is replaced by the micro-channel heat pipe adopted by the coupler so that heat dissipation effects of the coupler are improved. By using the high-frequency electrodeless lamp provided by the invention, the working temperature of the coupler can be effectively reduced, the coupling efficiency and the stability of a bulb are enhanced, and possibilities are provided for creating a larger-power high-frequency electrodeless lamp.

Description

technical field [0001] The invention relates to a lighting fixture, in particular to a bubble-type high-frequency electrodeless lamp with good heat dissipation. Background technique [0002] With the increasingly prominent contradiction between economic growth and resource shortage, energy saving and emission reduction has increasingly become a trend in the lighting industry. As a new type of electric light source, high-frequency electrodeless fluorescent lamps have the advantages of energy saving and long life. The high frequency electrodeless lamp consists of three parts: high frequency generator, coupler and bulb. The high-frequency generator first converts the mains power into a high-frequency strong voltage and transmits it to the coupler; the coupler functions like a transmitting antenna to couple the high-frequency signal into the bulb. Under the action of a high-frequency magnetic field, the loss (hysteresis loss and eddy current loss) generated by the coupler excit...
