Abstract
本实用新型属于电光源技术领域,是一种波导为超小型结构的微波硫灯。对应于2450mHz频率的微波,波导横截面长边为70～75mm,短边为40～45mm,长度为110～130mm,在波导的一侧面设置有一个金属调节块,以便使微波能匹配耦合到硫灯上去。本实用新型突破微波耦合腔的传统设计,使结构小巧,重量减轻,安装使用方便,而且发光效率也有所提高。同时,解决了波导小型化后的高频放电问题。
The utility model belongs to the technical field of electric light sources, and relates to a microwave sulfur lamp with an ultra-small waveguide structure. Corresponding to the microwave frequency of 2450mHz, the long side of the waveguide cross-section is 70-75mm, the short side is 40-45mm, and the length is 110-130mm. A metal adjustment block is set on one side of the waveguide so that the microwave can be coupled to the sulfur Light up. The utility model breaks through the traditional design of the microwave coupling cavity, makes the structure small and exquisite, reduces the weight, is convenient to install and use, and also improves the luminous efficiency. At the same time, the problem of high-frequency discharge after the miniaturization of the waveguide is solved.
Description
The utility model belongs to the electric light source technology field, is that a kind of waveguide is subminiature microwave sulfur lamp.
Microwave sulfur lamp is a kind of new type light source that developed recently gets up.Usually, it is made up of magnetron and antenna thereof, square wave guide cavity, post chamber, garden, electrodeless sulphur bubble, motor etc.Magnetron work, the generation frequency is that 2450mHz, power are the microwave of 1000W, pass through magnetron antenna, excitation square wave guide cavity, square wave guide cavity Transmission Microwave, and microwave energy is coupled to post chamber, garden by coupling aperture, microwave energy is transferred to electrodeless bulb in post chamber, garden, excite the bulb inner stuffing, form plasma luminescence.Wherein.The metal guard is generally adopted in post chamber, garden, and it can prevent that on the one hand microwave energy from leaking into the outside, and the light that can allow the sulphur bubble produce on the other hand appears.Rectangular waveguide adopts metal to make, and is rectangular body, and length is L, and cross section is a rectangle, and the long limit of note is a, and minor face is b.If waveguide is too little, on the one hand may the guided wave difficulty.On the other hand, the microwave energy volume density increases, and occurs spark phenomenon easily.When especially occurring big standing wave in the waveguide, regular meeting causes high-frequency discharge.Therefore,, generally adopt the waveguide of BJ22 type corresponding to the microwave of 2450mHz, its a=109.2mm, b=54.6mm, length L is about 200mm.Utilize the microwave sulfur lamp of this waveguide fabrication, its volume is big, seems heavy, uses inconvenience is installed.
It is little, in light weight that the purpose of this utility model is to propose a kind of volume, microwave sulfur lamp easy to install.
The microwave sulfur lamp of the utility model design also is made of magnetron and antenna thereof, square wave guide cavity, post chamber, garden, electrodeless bulb, motor etc., and its structure member is also identical with common microwave sulfur lamp with structural relation.Magnetron is located at rectangular waveguide one end downside, and coupling aperture is opened in rectangular waveguide other end upside; Post chamber, garden is a microwave cavity, is located at above the coupling aperture on the rectangular waveguide; Electrodeless bulb is positioned at resonant cavity, is swingle below, and this swingle is driven by motor.Wherein, the microminiature structure is adopted in waveguide, and promptly its transversal face length limit a is 70～75mm, and minor face b is 40～45mm, and the distance that therefore can dwindle microwave excitation district and coupling aperture greatly, and promptly length L is 110～130mm.Under this microminiature structure, steep up in order to make the microwave energy coupling be coupled to sulphur, in inboard middle part, a side of square wave guide cavity (L * b face) a metal regulating block is set.Whether the volume size of this regulating block effectively is coupled to sulphur to microwave energy is steeped up influential, promptly relevant with the luminous efficiency of lamp.Corresponding to above-mentioned waveguide, the volume of this regulating block is generally 3-7cm
3Proper, higher luminous efficiency is promptly arranged.And it is more convenient with the shape adjustment coupling of cuboid.Its structure as depicted in figs. 1 and 2.
Therefore, the microwave sulfur lamp of the utility model design, broken the traditional design of waveguiding structure, its volume is dwindled greatly, weight alleviates greatly, and its volume (waveguide part) only is original about 30%, and luminous efficiency does not only reduce, increase on the contrary, the match and regulate of regulating block is easy.Therefore, this microwave sulfur lamp structure is small and exquisite, easy to install, simultaneously, has solved the high-frequency discharge problem after waveguide small-sizedization.
Fig. 1 is the structural diagrams of this microwave sulfur lamp.
Fig. 2 is the cross section of half microwave sulfur lamp waveguide at the regulating block place.
Number in the figure: 1 is magnetron, and 2 is antenna, and 3 is the square wave guide cavity, 4 regulating blocks, 5 coupling apertures, post chamber, 6 garden, the swingle below the 7 celestial pole bulbs, 8 bulbs.
Embodiment, as shown in drawings, the square wave guide cavity adopts copper material, its long limit a=72mm, minor face b=43mm, length L=120mm tumbles in the metal regulating block in medial surface middle part, a side of square wave guide cavity (L * b face), is specially copper material, and its volume is 6.0cm
3The material of remaining part, structure and technology are identical with original microwave sulfur lamp, make the microwave sulfur lamp of microminiature waveguide thus.The technology of this lamp, performance index are consistent with original microwave sulfur lamp, and light efficiency increases.
