Abstract
Provided is an automobile daylight running light with a vacuum sealing cavity structure. The utility model relates to the technical field of automobile daytime running lights, and specifically relates to the improvement of a waterproof and moistureproof structure of the automobile daytime running light. the technical defect that moist air is easy to get into the automobile daytime running light is solved. The automobile daylight running light comprises a transparent cover, a reflecting cover, LED light sources, and a radiator. The automobile daylight running light with the vacuum sealing cavity structure is characterized in that the LED light sources are provided in the center of the reflecting cover, the reflecting cover is provided in the transparent cover, the transparent cover and the radiator form a sealing cavity, a vent hole is provided on the radiator, a sealing gasket and a sealing fastening screw are provided in the vent hole. In a testing process of high temperature ageing, the radiator and the transparent cover form a nearly vacuum sealing cavity, once the screw is fastened, air fails to flow back to the sealing cavity from the vent hole after being cooled, and the sealing cavity maintains a vacuum state; in the using process, no matter the light is heated by working or cooled by turning off the light, the air is not introduced to the sealing cavity, moist air is prevented from introducing to the cavity, and a special vacuum-controlling device is not capable of being provided in the production process, the realization of the light is easy, the structure is simple and practical, and the production cost is low.
Description
Technical field
The utility model relates to automobile day portable lighter technical field, is specifically related to the waterproof and dampproof architecture advances aspect of automobile day portable lighter.
Background technology
Because the led light source in the automobile day portable lighter in use can produce heat, for the loss that air in the lamp is avoided expanding with heat and contract with cold to reflection shield or transparent face mask is out of shape, present automobile day portable lighter reflection shield or or the face shield bottom row of being provided with air inlet through hole, row's air inlet through hole is located at the bottom can prevent that not only rainwater from flowing in the lamp, again can exhaust when being heated, air inlet during cooling; Though existing this structure can prevent that rainwater from flowing directly in the lamp, but after in wet environment, turning off the light, malaria will bounce back in the lamp from row's air inlet through hole in the interior air cooling of lamp, make Transparent lamp shade form atomizing, influence light transmittance, and reflection shield also therefore accelerated ageing influence reflecting effect.
Summary of the invention
In sum, the purpose of this utility model is to solve humid air and enters the interior technical deficiency of automobile day portable lighter easily, and proposes a kind of automobile day portable lighter of vacuum seal cavity configuration.
For solving the technical problem that the utility model proposes, the technical scheme of employing is: a kind of automobile day portable lighter of vacuum seal cavity configuration includes: transparent face mask, reflection shield, led light source and radiator; It is characterized in that: described led light source is located at the reflection shield center, and reflection shield is located in the transparent face mask, and transparent face mask and radiator constitute an annular seal space; Be provided with a steam vent at radiator, in steam vent, be provided with sealing gasket and sealing holding screw.
Described reflection shield is made of the reflection Lamp cup that is arranged in a row more than two, is provided with a LEDs light source in each reflection Lamp cup.
The described led light source that respectively reflects in the Lamp cup is located on the same pcb board.
Described radiator is provided with the heat radiation boss that punching press forms; Described heat radiation boss size is more than or equal to described pcb board, less than the transparent face mask opening.
The novel beneficial effect of this usefulness is: the utility model adopts and is provided with a steam vent at radiator, in steam vent, be provided with sealing gasket and sealing holding screw, in the high temperature ageing test process, radiator and transparent face mask constitute an annular seal space near vacuum, this moment tighten the screws, air can't be back to from steam vent in the annular seal space after cooling, annular seal space keeps vacuum state, no matter in the use be the work cooling of being heated or turning off the light, air all to the annular seal space circulation, has avoided humid air to enter, and can't set up special-purpose control vacuum equipment in the production process, realize that simple and practical, production cost is low easily.
