Abstract
The utility model discloses a close-type vacuum tungsten halogen lamp, which comprises a lamp housing, a lamp cover, a light emitting tube and a connection sheet. A reflecting mirror is provided on the inner surface of the lamp housing; the lamp cover and a fastening cap are arranged on the lamp housing; pins on the light emitting tube penetrates through a press cap and is fixed with the connection sheet; the lamp housing, the connection sheet and the fastening cap are adhered together via sealant; and the lamp cover is adhered to and fixed with the lamp housing. The utility model solves the disadvantages of the prior common close-type automotive front lamp, such as complex process and low yield. The lamp brightness can be improved by 2-3 times, and the service life can be prolonged by more than 2 times. The utility model has the advantages of simple production process, low production cost, high yield and no blackening of the reflecting mirror.
Description
Technical field
The utility model belongs to the illuminating lamp technical field, particularly a kind of closed vacuum halogen tungsten lamp.
Background technology
At present, the closed vacuum halogen tungsten lamp structure of using on the automobile generally includes lamp socket, interior cover, the crown top of burner, bakelite, inserted sheet, and inserted sheet is provided with wire hole and fixedly is embedded on the bakelite, lamp socket is fixedlyed connected with bakelite, crown top of burner end opening flange, interior cover is inserted in the crown top of burner, and both live and join.During use, it is fixing that bulb is inserted interior cover, after interior cover being inserted in the optically focused of focusing in the crown top of burner interior cover is fixedlyed connected with crown top of burner butt-joint, the bulb seal wire passes from the wire hole of inserted sheet, crown top of burner end opening flange is overlayed on the lamp socket by some somes spot welding the crown top of burner to be fixedlyed connected with lamp socket again.Advantage is that the optically focused of focusing makes good illumination effect, traffic safety.Weak point is that parts are many, material cost is high, complex manufacturing, yield rate are low.And some automobile front lamp holder causes the optically focused of can not focusing owing to save interior cover, make illuminating effect poor, influence traffic safety.
The utility model content:
In order to overcome the deficiencies in the prior art, the purpose of this utility model provides a kind of closed vacuum halogen tungsten lamp, the existing automobile front complex manufacturing of solution, the defective that yield rate is low.
For achieving the above object, the technical scheme that the utility model adopted is: closed vacuum halogen tungsten lamp comprises lamp housing 1, lampshade 2, luminous tube 3 and brace 4.The inner surface of lamp housing 1 is provided with reflective mirror, and lamp housing 1 is provided with lampshade 2 and fastening cap 5, and it is fixing with brace 4 that the lamp base 6 on the luminous tube 3 passes pressure cap 7, and lamp housing 1, brace 4 and fastening cap 5 bond together by fluid sealant.
Described lampshade 2 is adhesively fixed with lamp housing 1.
The beneficial effects of the utility model are: after adopting said structure, solved existing common closed automotive headlight complex manufacturing, defective that yield rate is low.And the brightness of lamp can improve 2-3 doubly, and can prolong more than 2 times service life.Have that production technology is simple, production cost is low, yield rate is high, reflective mirror can not cause advantages such as melanism.
