Body of sulfur lamp with tuner

Abstract

Body of sulfur lamp in use for microwave sulfur lamp is composed of bulb of sulfur lamp and handle of lamp connected to each other. Being installed on the handle of lamp, cylindrical tuner with radius in 20mm-40mm, thickness in 25mm-30mm is placed at distance 5mm-20mm between bulb of sulfur lamp and up surface of the tuner. The tuner made from quartz is in hollow structure. Body of sulfur lamp with the tuner being installed will reduce reflected microwave energy so as to lighten harm on magnetron, and shorten time of lighting up bulb of sulfur lamp.

Description

1. Technical field [0001] The invention relates to a sulfur lamp body for a microwave sulfur lamp, in particular to a sulfur lamp body for a microwave sulfur lamp which can increase the electric field intensity at the bulb position of the sulfur lamp and reduce energy reflection. 2. Background technology [0002] Microwave sulfur lamp is a new type of light source that adopts a new light-emitting mechanism, which has the advantages of energy saving, long service life, good light color and less pollution. Its luminescence process is like this. [0003] Referring to Fig. 1 and Fig. 2, the sulfur lamp bulb 2 is placed in the resonant cavity 1, and is rotated by the motor 7 through the lamp handle 8, and the fan 10 plays a cooling role; the magnetron output part 5 of the magnetron 6 is inserted into the waveguide In the cavity 4, the microwave energy emitted by the magnetron 6 is transmitted by the waveguide cavity 4, and then transmitted to the resonant cavity 1 through the ra...

AI Technical Summary

Problems solved by technology

[0004] In this process, due to the transmission of microwave energy in the waveguide cavity 4 and the coupling process of the energy in the resonant cavity 1, factors such as the surface roughness of the waveguide cavity 4 or gaps caused during the assembly process will cause it to resonate with The matching problem is caused in the coupling process of the cavity 1, which causes the standing wave ratio in the resonant cavity 1 to increase, and makes a part of the energy finally concentrated in the sulfur lamp bulb 2 reflected back to the waveguide cavity 4

As a result, the following problems will inevitably be caused: firstly, the reflected microwave energy will cause damage to the magnetron 6, and being in this working state for a long time will easily cause damage to the magnetron 6; The energy in the center of the sulfur lamp bulb 2 is insufficient, which makes the lighting time of the sulfur lamp bulb 2 slower
