Description

The electrodeless lamp of microwave discharge
One, technical field
The utility model relates to electrodeless lamp electric light source field, particularly a kind of microwave discharge light source technology.
Two, background technology
Since last century, the nineties microwave sulfur lamp came out, increasing by means of the light source of microwave discharge.This class light source is summed up, its agent structure all has four partly to constitute: the magnetron that produces microwave, the waveguide of coupling, Transmission Microwave produces the resonant cavity and the electrodeless bulb of microwave discharge, here, microwave cavity is the core component of electrodeless lamp, microwave cavity adopts netted cylindrical cavity usually, still, forms the coupling slit between resonant cavity resonant cavity and the waveguide, be two big difficult points of the electrodeless lamp of this class, make quite difficulty.
The electrodeless lamp of another kind of microwave discharge, there is not the coupling slit in microwave cavity yet, directly utilizes waveguide discharge and the electrodeless lamp that constitutes.A kind of microwave light source of announcing of Japanese patent laid-open 9-245746 for example.Remove resonant cavity and slit, direct utilization has the network structure waveguide discharge and forms.But experiment finds that the stimulation effect of the electrodeless lamp of this class in recent years, was sought novel simple and effective microwave discharge light source method and apparatus, always in constantly carrying out not as having the sort of good of resonant cavity.
In addition, the inventor also number of patenting once is " a kind of microwave plasma light source " patented technology of 200420032780.X, produce the magnetron of microwave by the variable frequency power supply power supply, the one section tubaeform waveguide that links to each other with magnetron, compositions such as the metallic shield net of connection waveguide and electrodeless bulb.Practice shows that the electrodeless bulb in the above-mentioned technology all is positioned over the rectangular waveguide mouth, thereby electrodeless bulb partly is positioned at the metallic shield net, and part is positioned at rectangular waveguide, causes the light source of considerable part to be disabled waste.
Three, summary of the invention
The purpose of this utility model is the deficiency that overcomes the existing electrodeless lamp of microwave discharge, designs a kind of compactness and the be not coupled electrodeless lamp of microwave discharge of slit of the high existing resonant cavity of light efficiency.
Basic ideas of the present utility model are, use for reference the structure in magnetron hole slot chamber commonly used, apply on the microwave discharge light supply apparatus, and its electrodeless bulb place the metallic shield net fully, reach simple and effective practical purpose.
The utility model is specifically realized by following scheme: the electrodeless lamp of a kind of microwave discharge, the magnetron that comprises the band magnetron antenna that produces microwave, one one terminal shortcircuit other end opening and have the rectangular waveguide of ring flange, magnetron antenna is arranged in rectangular waveguide, a port has the metallic shield net of ring flange, an electrodeless bulb, fixedly connected between rectangular waveguide ring flange and the metallic shield net ring flange, it is characterized in that electrodeless bulb is arranged in the metallic shield net, the metallic shield net be shaped as semiellipse face body or spherical surface body, rectangular waveguide and metallic shield net are formed the ball slot type resonator.Like this, electrodeless bulb is placed the spherical cavity of ball slot type resonator fully, and the luminous energy that electrodeless bulb sent accesses to greatest extent and effectively utilizes.
Further scheme is: be fixed with the adjustment of inductance piece on the rectangular waveguide inwall, along the rectangular waveguide cross section medium mica sheet be installed.Regulate the adjustment of inductance piece, can realize the impedance matching of microwave system.
Electrodeless bulb is by quartz pushrod, and transition joint links to each other high speed rotating with the electrical micro-machine output shaft.Electrodeless bulb is generally quartzy bead, in be filled with luminescent substances such as high purity sulphur or metal halide, and be filled with certain startup gas such as argon gas.
Described rectangular waveguide, ring flange, semiellipse face body metallic shield net are generally aluminium and make, and semiellipse face body metallic shield net will be handled with chemical etch polishing.
The power supply of magnetron is generally frequency 〉=100HZ variable frequency power supply.
The utility model compared with prior art has the light efficiency height, advantages such as compact conformation.
Four, description of drawings

Fig. 2 is the agent structure side-looking band portion profile of the utility model embodiment.
Fig. 3 is the ball vallecular cavity generalized section of the utility model embodiment.
Among the figure: 1, electrodeless bulb, 2, magnetron, 3, rectangular waveguide, 4, magnetron antenna, 5, semiellipse face body (metallic shield net), 6, (rectangular waveguide) ring flange, 7, (metallic shield net) ring flange, 8, adjustment of inductance piece, 9, the medium mica sheet, 10, the magnetron coupling aperture.
Five, embodiment
Below in conjunction with accompanying drawing the utility model is done detailed description:
As Fig. 1, Fig. 2 and Fig. 3, the electrodeless lamp of a kind of microwave discharge, comprise the magnetron 2 that produces the band magnetron antenna 4 of microwave by the variable frequency power supply power supply, one one terminal shortcircuit other end opening and have the rectangular waveguide 3 of ring flange 6, magnetron antenna 4 is arranged in rectangular waveguide 3, a port has the metallic shield net 5 of ring flange 7, an electrodeless bulb 1, fixedly connected between ring flange 6 and the ring flange 7, it is characterized in that electrodeless bulb 1 is arranged in metallic shield net 5, the semiellipse face that the is shaped as body of metallic shield net 5, rectangular waveguide 3 and metallic shield net 5 are formed the ball slot type resonator.Be fixed with two adjustment of inductance pieces 8 on rectangular waveguide 3 inwalls, on adjustment of inductance piece 8, medium mica sheet 9 be installed along rectangular waveguide 3 cross sections.Magnetron 2 links to each other with rectangular waveguide by coupling aperture 10.
Experiment shows, under the power supply of 600W variable frequency power supply, can obtain light efficiency 100Lm/w.Show index>80, colour temperature 5000-7000k lighting source.
