Abstract
The utility model discloses a microwave electrodeless light source which comprises a magnetron 1, a microwave waveguide cavity 2, a microwave energy feed port 3, a microwave resonance cavity 4, an electrodeless lamp tube 5 and a microwave shielding cover 6 and is characterized in that a metal shell is divided into the microwave waveguide cavity 2 and the microwave resonance cavity 4; the microwave energy feed port 3 is formed between the microwave waveguide cavity 2 and the microwave resonance cavity 4; the electrodeless lamp tube 5 is arranged in the microwave resonance cavity 4; and the shape of the inner upper part of the microwave resonance cavity 4 is in the shape of a light-reflecting cover. Compared with the existing product, the light source has the characteristics of high effect, low fault rate and the like.
Description
Technical field
The utility model belongs to electronic technology field, and he is particularly related to the microwave non-electrode light source.
Background technology
Traditional microwave non-electrode light source is made up of magnetron, microwave waveguide, microwave energy-feeding mouth, microwave cavity, electrodeless fluorescent tube, light reflecting cover, micro-wave screening cover etc.Wherein having the microwave energy-feeding mouth on the light reflecting cover, is again the part of microwave waveguide chamber and microwave cavity simultaneously.The shape of light reflecting cover will preferentially guarantee optical property, so it can't satisfy the optimization of electromagnetic parameter, causes phenomenons such as conversion efficiency is low, magnetron life decline, lamp lighting-up difficulty; Owing to exist huge energy difference between microwave waveguide chamber and the microwave cavity, discharge very easily take place between light reflecting cover and the cavity strike sparks fault and damage parts.
Summary of the invention
The purpose of the utility model provides the microwave non-electrode light source that a kind of effect is high, failure rate is low with regard to being to be directed against the defective of above-mentioned prior art.
Its technical solution is following:
The utility model microwave non-electrode light source is by magnetron 1, microwave waveguide chamber 2, microwave energy-feeding mouth 3, microwave cavity 4, electrodeless fluorescent tube 5, micro-wave screening cover 6; It is characterized in that microwave waveguide chamber 2 and microwave cavity 4 are to be separated by a metal shell; Be microwave energy-feeding mouth 3 between microwave waveguide chamber 2 and the microwave cavity 4; Electrodeless fluorescent tube 5 is arranged in the microwave cavity 4, and the internal upper part of microwave cavity 4 is shaped as the reflection shield shape.
Electrodeless fluorescent tube 5 can send multi-wavelength's ultraviolet, infrared, visible light etc. for quartz glass tube by the gas difference of its filling.
The present invention adopts the method that electromagnetical analogies calculates and test combines that microwave waveguide chamber, microwave cavity and microwave energy-feeding mouth are designed.Effectively improve the conversion efficiency of system, guaranteed the normal useful life of magnetron; Adopted the integrated design of light reflecting cover and microwave cavity, avoided the fault that causes because of discharge sparking, improved the reliability of system and reduced maintenance cost.
The electromagnetic performance of the utility model microwave non-electrode light-source system is superior to technology in the past.It shows following
Several aspects: 1. the easy build-up of luminance of fluorescent tube, the utility model use the 1KW magnetron to make microwave source, and the fluorescent tube of three producers is carried out the build-up of luminance test; The result all can light; And technology used in the past is the magnetron of 3KW, and except that oneself fluorescent tube, the fluorescent tube of other producers can only partly be lighted; Caloric value is low; The utility model system is only cooled off magnetron with the small-sized fans of a 30W; Get final product operate as normal, and technology must be used the above blower fan of 500W and through the clean air that filters magnetron and fluorescent tube cooled off the ability operate as normal in the past; Thermal radiation is low in the output light, and the utility model system do not have to force under the cooling situation, and the shone thing temperature is no more than 130 ° of C apart from lamp front end face 50mm place, and technology also can surpass 200 ° of C under the pressure cooling condition (do not cool off and can't work) in the past; Because the utility model system does not need special cooling to work, and greatly facilitates client's use, because thermal-radiating significantly reduction in the utility model system output light, and make the materials processing of many poor heat resistance become possibility.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
The utility model comprises magnetron 1, microwave waveguide chamber 2, microwave energy-feeding mouth 3, microwave cavity 4, electrodeless fluorescent tube 5, micro-wave screening cover 6; Microwave waveguide chamber 2 is to be separated by a metal shell with microwave cavity 4; Be microwave energy-feeding mouth 3 between microwave waveguide chamber 2 and the microwave cavity 4; Electrodeless fluorescent tube 5 is arranged in the microwave cavity 4, and the internal upper part of microwave cavity 4 is shaped as the reflection shield shape.
The microwave that magnetron 1 is launched through microwave waveguide chamber 2 and microwave energy-feeding mouth 3 get into microwave cavities 4; When the electromagnetic energy that places microwave cavity 4 electrodeless fluorescent tubes 5 places reaches certain value, can cause the gas generation ionization in the fluorescent tube and inspire light such as ultraviolet light.
It is pointed out that above-mentioned execution mode and accompanying drawing only are that it is not limited in above execution mode, can decide as the case may be like the shape of microwave waveguide chamber, energy regenerative mouth, resonant cavity, reflection shield etc. to the illustrating of the utility model.
