Abstract
The utility model relates to a straight type alumina ceramics electric arc tube which comprises a cylinder-shaped straight tube with a cavity, wherein two ends of the straight tube are respectively provided with a bottle plug type cover portion which is made of the same materials with the cylinder-shaped straight tube. The cover portion is a cylinder-shaped structure, one end of the cylinder-shaped structure is provided with a round and outward extension portion, the external diameter of each cylinder-shaped structure at the end is matched with the inner diameter of the straight tube, and inner holes which are communicated with the straight tube are arranged at the centers of the cover portions.
Description
Technical field
The utility model relates to the metal halid lamp electric arc tube, particularly relates to a kind of straight type 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.
Existing cylindrical aluminium oxide ceramics electric arc tube mainly is cylindrical straight tube of one processing; End cap is made with metal in two ends; Electrode is fixed with insulating material with metal end and is isolated; This structure brings many inconvenience for the postorder work of light fixture, and developing a kind of aluminium oxide ceramics electric arc tube that can be convenient to postorder processing is the problem of the required solution in this area.
Prior art is used the two ends of cylinder straight tube are directly in aggregates with straight tube; Though this processing mode can guarantee the integraty of electric arc tube; But this processing mode can only adopt the half the mode of electric arc tube to process base substrate and then two parts are carried out presintering and be processed into a cylindrical structural; This just makes the thickness of centre of electric arc tube greater than other wall thickness, and percent defective is higher simultaneously to influence translucent effect.
The applicant is utilized in the industry technology for many years and the summary of experience, and existing cylindrical straight tubular construction is proposed an improvement scheme, and this scheme no longer needs the metal end of lamp tube ends, directly electrode is inserted the making that electric arc tube is promptly accomplished light fixture.
The utility model content
The purpose of the utility model provides a technical scheme, makes electrode directly be installed on the two ends of ceramic arc tube, no longer needs the metal end at former cylindrical straight tube two ends.
The utility model is realized through following technical scheme:
Straight type aluminium oxide ceramics electric arc tube; Include the cylindrical straight tube of a band cavity; Respectively there is a bottle stopper formula cap with the identical material of cylindrical straight tube at the two ends of said straight tube, and said cap is the cylindrical structural that an end has circular extension, and the cylindrical outer diameter of said end matches with the internal diameter of straight tube; The endoporus of the center of said cap for communicating with straight tube, the diameter of the circular extension of said cap is identical with the external diameter of straight tube.
The thickness of the circular extension of said cap is identical with the wall thickness of straight tube.
The beneficial effect of the utility model is:
Through the present technique scheme, with pack into the fixing making of just accomplishing light fixture of endoporus blended rubber body of cap of electrode, operation is simple.

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 depicted in figs. 1 and 2, straight type aluminium oxide ceramics electric arc tube includes the cylindrical straight tube 11 of a band cavity; Respectively there is a bottle stopper formula cap (12 with the identical material of cylindrical straight tube at the two ends of said straight tube; 13), said cap is the cylindrical structural that an end has circular extension, and the cylindrical outer diameter of said end matches with the internal diameter of straight tube; The endoporus of the center of said cap for communicating with straight tube, the diameter of the circular extension of said cap is identical with the external diameter of straight tube.
In burning the casting process, make the ceramic body of straight tube and cap at first respectively, the base substrate of two caps is packed on the straight tube base substrate, carry out presintering processing and later stage operation, the straight tube of the electric arc tube of so last moulding becomes as a whole with cap.
The thickness of the circular extension of said cap is identical with the wall thickness of straight tube in the present embodiment, and in other embodiments, can the get along well wall thickness of straight tube of the thickness of the circular extension of cap is identical, and such variation does not influence the technical scheme of this patent.
The center of said cap is the aperture of the endoporus that communicates with the straight tube internal diameter less than straight tube; Generally with the aperture of the endoporus of cap be straight tube internal diameter 1/3rd to 1/4th between; The purpose of selecting so mainly is the installation that is beneficial to electrode; If the aperture of cap endoporus is excessive, just need too much fixedly operation or material during installing electrodes, do not reach the purpose of this patent.
The length of said cap cylindrical structural is 5mm-20mm, if the length of the cylindrical structural of cap is too short, can not realize the firm of electrode, if long increase cost.
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.
