Abstract
The utility model relates an aluminum oxide ceramic tube for a metal halide lamp. The aluminum oxide ceramic tube for the metal halide lamp comprises two plugs, each plug is in an integrated structure which is formed by a tail pipe and a ceramic cap arranged at one end of the tail pipe, each ceramic cap is formed by connecting a circular barrel and an arc-shaped pipe, each ceramic cap is connected with the tail pipe in transition mode through the arc-shaped pipe on the ceramic cap, and each arc-shaped pipe is communicated with the tail pipe.
Description
Technical field
The utility model relates to lighting field, particularly relates to metal halide lamp and uses alumina ceramic tube.
Background technology
Advantages such as the semitransparent ceramics that adopts polycrystal alumina has the working temperature height as the metal halid lamp of fluorescent tube 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 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 fluorescent tube.
The utility model is realized through following technical scheme:
Metal halide lamp is used alumina ceramic tube; Comprise two plugs; Each plug is the integrative-structure of tail pipe and the ceramic cap formation that is arranged at tail pipe one end; Ceramic cap is that circular cylinder and camber pipe connect and compose, and ceramic cap is connected with the tail pipe transition through the camber pipe on it, and curved pipe is connected with tail pipe.
Round tube length in said two ceramic caps is unequal, and the length of one of them circular cylinder is 2 times of another circular cylinder length.
The wall thickness of curved pipe is 5/4 of a circular cylinder wall thickness in the said ceramic cap.
The beneficial effect of the utility model is:
Through the technical scheme of the utility model, connect through the ceramic cap interference with two plugs of earthenware, its good seal performance improves the cold and hot stress of lamp when guaranteeing light transmittance.

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.
Metal halide lamp is used alumina ceramic tube, comprises two plugs (11,12); Each plug is the integrative-structure that tail pipe (15,16) and the ceramic cap that is arranged at tail pipe one end constitute, and ceramic cap is circular cylinder and camber pipe (13; 14) connect and compose, ceramic cap is through camber pipe (13,14) on it and tail pipe (15; 16) transition connects, and curved pipe is connected with tail pipe.
In the utility model, the processing mode of aluminium oxide base substrate is not that the application requires the scope protected, therefore can select any suitable base substrate mode of production for use; In this application through biscuiting and sintering processing production; For the needs that guarantee to assemble, the biscuiting temperature of two plugs is different, step (171 outside two plug contact seals place are; The biscuiting temperature of plug 172) is higher than the biscuiting temperature of another plug, and the temperature difference is at 150-200 degree centigrade.Each plug comprises that tail pipe is one-shot forming in the base substrate manufacturing.
Round tube length in said two ceramic caps is unequal, and the length of one of them circular cylinder is 2 times of another circular cylinder length.
The wall thickness of curved pipe is 5/4 of a circular cylinder wall thickness in the said ceramic cap.
The described metal halide lamp of the utility model is used alumina ceramic tube, is applicable to the 20W-800W metal halide lamp.
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.
