Abstract
The utility model relates to an aluminum oxide ceramic arc tube. The aluminum oxide ceramic arc tube comprises two cylindrical hollow main bodies combined together, wherein one end of each cylindrical hollow main body is provided with a hemispherical end face, and the cylindrical hollow main bodies extend outwards from the hemispherical end faces to form tail tubes along the way from the axis of the cylindrical hollow main bodies to the hemispherical end faces; the tail tubes are hollow tubes and pass through the hemispherical end faces; and the other ends of the two cylindrical hollow main bodies are combined with each other in a step manner.
Description
Technical field
The utility model relates to the metal halid lamp electric arc tube, particularly relates to a kind of aluminium oxide ceramics electric arc tube.
Background technology
Advantages such as the semitransparent ceramics that adopts polycrystal alumina has the working temperature height as the metal halid lamp of arctube material, and light efficiency is high, and light decay is little, and good and life-span of colour developing is long.
Current ceramet Halogen lamp LED electric arc tube mainly adopts the translucent alumina ceramics manufacturing, and switch mainly contains cylindrical, and cylinder and circular cone are combined; Elliposoidal; But existing these types are the complicated difficult processing of processing technology, and need add forming agent during fabrication, improve production cost.
The utility model content
The purpose of the utility model is to provide a kind of production efficiency high, and technology does not simply need forming agent and has high dimension precision, and long-life metal halid lamp is used the transparent alumina ceramics electric arc tube.
The utility model is realized through following technical scheme:
A kind of aluminium oxide ceramics electric arc tube; Include two cylindrical hollow main bodys that combine; One end of each said cylindrical hollow main body is provided with hemispherical end face; Along said cylinder-shaped body axle center to hemispherical end face be the center from the hemispherical end face formation tail pipe that stretches out, said tail pipe is hollow pipe and penetrates hemispherical end face that said tail pipe axle center is same straight line with the cylinder-shaped body axle center; The other end of said two cylindrical hollow main bodys combines with the step mode each other.
The utility model technology is simple, and the dimensional accuracy of ceramic arc tube is high behind the sintering, and it is long to have a life-span, light efficiency height, characteristics such as the little and color rendering height of light decay.

Embodiment
Below in conjunction with the concrete technical scheme of accompanying drawing detailed description the utility model, the specific embodiment of the utility model only is exemplary, can only be used to explain the utility model and can not be interpreted as to be the restriction to the utility model.
As shown in the figure, a kind of aluminium oxide ceramics electric arc tube includes two cylindrical hollow main bodys (11 that combine; 12), each said cylindrical hollow main body (11,12) end is provided with hemispherical end face (13; 14) be that the center stretches out and forms tail pipe (15,16) to hemispherical end face, along said cylinder-shaped body axle center; Said tail pipe is hollow pipe and penetrates hemispherical end face that said tail pipe axle center is same straight line with the cylinder-shaped body axle center; The other end of said two cylindrical hollow main bodys combines (171,172) with the step mode each other.
The wall thickness of said cylinder-shaped body is 0.4-1.2mm, and said wall thickness is directly proportional with the power of electric arc tube.
The wall thickness of said hemispherical end face is 1.3 times of cylinder-shaped body wall thickness.
The hemispherical end face place bore of said tail pipe greater than by the end bore, and in the tail pipe without leave the hemispherical end face place to by the place seamlessly transit.
In the utility model, comprise two two cylindrical hollow main bodys, two hemispherical end face and two tail pipes, described two hemispherical end face are identical, and two tail pipes are identical.
The processing method of the utility model is directly to adopt polycrystal alumina powder Hpdc moulding process; 350MP-500MP pressure die cast is adopted in said die casting; With carrying out presintering after the parison assembling, so just need not re-use forming agent then, reduce the pollution of environment.
The above only is the specific descriptions to the utility model technical scheme, and those skilled in the art can improve according to the present technique scheme certainly, and these improvement should be considered in the protection range of the utility model.
Claims (4)
