Microwave sulfur lamp

Abstract

The invention provides a kind of microwave sulfur lamp, includes the wave-guide that is consisted of cover board, wave-guide cavity, allocation block, the said allocation block is designed and formed wholly at one side end of the cover board of the inner cavity that forms the wave-guide. The effect of the invention is to use the structure to make the microwave sulfur lamp, since the original cover board and the triangular column shape allocation block are made in a whole, which saves the process of using screw to make the connection, and conveniently it can assemble into a wave-guide cavity, which can not only improve the production efficiency, but also is beneficial to protect the relativistic magnetron. Normally it uses the method of compensation reflection to eliminate the microwave reflection, its reflection elimination ability does mainly depends on its volume. Similarly, the effect of installing it at the end of the wave-guide after changing it into a triangle is almost same as the one of installing it at the side. It produces reserve reflection at the end of the wave-guide and then eliminates the microwave it is reflected back from the resonant cavity. It can produce the allocation block and the wave-guide cover as a whole to solve the problem of installation. Therefore the end section of the inner cover board of the wave-guide is chosen as the improved allocation block position.

Description

technical field [0001] The invention relates to a microwave sulfur lamp in terms of light sources. Background technique [0002] A general microwave sulfur lamp is shown in Figure 1. It is mainly composed of a magnetron 1, a waveguide cavity 3, a bulb motor 4, a resonant cavity 5 and a quartz bulb 7. The length of the waveguide 3 is the wavelength of the microwave emitted by the magnetron. Integer multiples are: nλ. [0003] The waveguide is one of the main components of the microwave sulfur lamp, and its function is to transmit the microwave generated by the magnetron to the resonant cavity. It is generally realized by using a waveguide with a rectangular cross section. However, during the microwave transmission process of the rectangular waveguide, part of the microwave reflection will bombard the magnetron, resulting in a reduction in the life of the magnetron. In order to protect the magnetron, a compensation reflection method is adopted, and a metal allocation block ...

Problems solved by technology

But it needs to be fixed with screws, which is troublesome

Moreover, it is easy to damage the inner surface of the waveguide 3 during the fixing process.
