A kind of reflective automobile back tail lamp of high temperature resistant height
Technical field
This utility model relates to automobile lamp technical field, particularly relates to a kind of high temperature resistant height
Reflective automobile back tail lamp.
Background technology
Total in the design process of automobile lamp, owing to needs ensure that light fixture is in high and low temperature environment
Can normally work, and need the feature of light weight in view of light fixture, generally use moulding to make
Car light parts for car light shell and inner cover etc..But the light fixture of moulding is in work process
In, it is susceptible to soften, chaps, deforms, the potential failure mode such as gloss change so that
Light fixture cannot normally work.
There is main reason is that of drawbacks described above: the lamp interior useful space is the least, part material
Material heat resistance is poor, and material heat resisting temperature is inadequate, poorly sealed at lamp holder hole, light fixture space
The phenomenons such as design portion is reasonable cause.
But the heat that high sealing performance makes car light produce cannot come out, the most outward
The service life of automobile lamp can be affected.So ensureing the same of automobile lamp high sealing performance
Time, the heat radiation of rational design vehicle car light, serviceability and the service life to automobile lamp
There is strong influence.Additionally the requirement of light fixture is also constantly being promoted, to light fixture by client now
Aesthetic property it is also proposed new requirement, light fixture should its luminous intensity distribution performance country to be met attractive in appearance
Standard-required.
Summary of the invention
According to the problems referred to above, the purpose of this utility model is to provide a kind of high temperature resistant height reflective
Automobile back tail lamp, its object is to improve the brightness of automobile lamp, especially automobile tail light,
And the time worked under high and low temperature environment, improve the weatherability of car light, thus improve Automobile
The potential safety hazard that lamp is brought, and ensure that the service life that car light is longer simultaneously.
The technical solution of the utility model is achieved in the following ways: a kind of high temperature resistant height is anti-
Light automobile back tail lamp, including Combined lamp shade and combination lamp housing, described Combined lamp shade, combination lamp housing,

Put reverberation bowl and turn to connecting portion between reverberation bowl to be divided into "Ji" type, turn to reverberation bowl with after
Between mist reverberation bowl, connecting portion is divided into "Ji" type, and the inner surface of combination lamp housing is provided with aluminium coated,
Reverberation bowl on described combination lamp housing is positioned on the aluminium coated directly over light source connection one piece of suction
Light film.
Being installed with decoration inner cover on the reverberation bowl of described position, decoration inner cover is provided with multiple flower
Stricture of vagina: such as strip decorative pattern, sparrow pecked etc..
Described light source assembly is made up of with light source seal cartridge, and the liner body part of seal cartridge is
The double-decker of inner hollow.
The material of described Combined lamp shade is polymethyl methacrylate, and the material of combination lamp housing is work
Engineering plastics alloy PC+ABS.
Enhancing location division it is additionally provided with on described combination lamp housing.
This utility model, improves the utilization of light by combination envelope inner surface aluminium coated and reverberation bowl
Rate, improves the brightness of automobile tail light, and the time worked in high temperature environments, improves car light
Weatherability, prevents from occurring under high-temperature condition burning melting the situation combining lamp housing, thus improves Automobile
The potential safety hazard that lamp is brought, and ensure that the service life that car light is longer simultaneously.
