Abstract

The utility model provides an improved enclosed automobile anti-mist bulb. The improved enclosed automobile anti-mist bulb comprises a tapered glass shell which is symmetrical to an axial line, a far-light filament and a near-light filament which are installed at the bottom of the glass shell, and corresponding nickel stem, corresponding nickel cobalt, a corresponding electric-conduction inserting sheet and a corresponding exhaust pipe. The inner cone surface of the glass shell is a reflecting mirror face. A paraboloid transmitting mirror which is sealed and connected with an end opening of the glass shell is 5 number material transparent glass, and the 5 number material transparent glass has homogeneous yellow or golden yellow color and is manufactured by making use of special technology; thus, the chrominance of the yellow or the yellow light of an automobile lamp is good, the illumination quality is stable, and the utility model avoids the defect that the surface of the colourless glass is coated with a yellow coating layer structure. The utility model has the advantages of long life time and good mist-permeating performance. The utility model is particularly suitable for multi-mist regions in the China to be used as an automobile anti-mist headlight.

Description

The antifog bulb of closed automotive

The utility model relates to a kind of automotive lamp, the antifog bulb of particularly a kind of closed automotive.

The head light of automobile has open type (bulb promptly is installed) and closed (promptly whole bulb is made the glass obturator big just as lamp shade, and headlight high beam filament and dip filament are housed therein) in lamp shade at present.The glass obturator of closed car light by the cone-shaped glass shell of making mirror surface, be tightly connected and be paraboloidal diaphotoscope and forms with glass bulb, also is provided with filament, conducts electricity relevant connecting element and connector.Particularly in order to improve the safety that vehicle travelled in the greasy weather, alleviate the tired consumptive disease of driving, make above-mentioned closed head light can send that illumination is bright, mist transmitting good, yellow or golden yellow near, the distance light that visbility is high, many manufacturers are designed to the colourless transparent glass body with the diaphotoscope of above-mentioned closed head light one after another, add the structure of outside face spraying last layer yellow paint, though can make car light send yellow light, but the yellow coating hardness in diaphotoscope surface is poor, easily scuffing, poor adhesive force, easily come off, also easily fade, these have all directly influenced its service life and illumination quality.

The purpose of this utility model is to provide a kind of improved closed automotive antifog bulb, its long service life, and can guarantee yellow or golden yellow illumination steady quality.

Task of the present utility model is finished like this: the antifog bulb of closed automotive comprises the cone-shaped glass shell with the axis symmetry, be installed in glass bulb bottom instant and near light filament and corresponding nickel cobalt, conduct electricity inserted sheet, freeing pipe and be connected and be paraboloidal diaphotoscope with the glass bulb port sealing, the glass bulb inner conical surface is a mirror surface.It is characterized in that: described diaphotoscope is No. 5 material clear glasses that are yellow or golden yellow homochromatic, and its periphery coincide with glass bulb, and seals with sintering processing.

Make the Fog-proof light diaphotoscope owing to adopt special process to make with No. 5 material clear glasses of yellow or golden yellow homochromatic, so make the Fog-proof light that is exclusively used in emission yellow or golden yellow light avoid doing the defective of diaphotoscope with flint glass surface spray yellow or golden yellow coating structure, it is yellow or golden yellow light colourity is good, the illumination steady quality, mist transmitting is good, long product lifecycle especially is suitable for foggy area, China southwest and makes the antifog head light of automobile.

Below with accompanying drawing in conjunction with the embodiments, concrete structure of the present utility model is further described again:

Fig. 1 is the front view of a kind of automobile anti-fog lamp bubble that provides of the utility model.

Fig. 2 is the left view of Fig. 1 structure.

Fig. 3 is the right elevation of Fig. 1 structure.

As shown in the figure, glass bulb 7 inner conical surfaces of automobile anti-fog lamp bubble are that aluminium coated is done, mirror surface 7.1, nickel cobalt 6 and nickel stalk 3 are equipped with in glass bulb 7 bottoms, and correspondingly be wound with headlight high beam filament 2 and dip filament 8, the outer end of every utmost point nickel stalk links to each other with conduction inserted sheet 4, the glass bulb bottom also is provided with freeing pipe 5, with to vacuumizing in the osed top bulb, sealing behind the filling with inert gas, taking out, inflating after processing severed by accident for fear of freeing pipe, in sintering is repaired once more, destroy the aluminium coated of glass bulb bottom, so this structure aluminium coated does not plate transparent circle in bottom of shape in glass bulb inner conical surface bottom.Be connected and be paraboloidal diaphotoscope 1 with the glass bulb port sealing, No. 5 material clear glasses of the yellow or golden yellow homochromatic that the employing special process is made are made the Fog-proof light diaphotoscope, and its periphery is identical with glass bulb 7, and with sintering processing both is sealed.With the plug-in of dipped beam conduction, distance light conduction inserted sheet bonded assembly nickel stalk, be connected with nickel stalk on the public conduction inserted sheet respectively among Fig. 3 by filament.3 groups of projections 9 at bulb back edge are to make the limiting stopper that bulb is installed.The glass bulb port of this structure automobile anti-fog lamp bubble both can be circular as shown in this embodiment, it also can be the (not shown) of rectangle, certainly being still with the taper of axis symmetry of its formation made mirror surface, and therefore the diaphotoscope that matches also correspondingly adopts circle or rectangle.

Claims
