Abstract
The utility model relates to a heat dissipation demisting device for automobile lamps, which comprises a fan, a connecting socket and an air exhaust pipe. The fan is a centrifugal fan and installed inside a lamp shell, an air inlet of the fan corresponds to an air vent of a reflector, the connecting socket is fixed at a lateral air outlet of the fan, an air inlet of the air exhaust pipe is mounted on the connecting socket and communicated with the lateral air outlet of the fan, and an air outlet of the air exhaust pipe is located in the corner at the lower portion of a lamp cover. The heat dissipation demisting device for the automobile lamps can reduce the temperature of the position inside a lamp and closer to a light source, enables the position of the lamp cover farther from the light source to have a certain temperature, better achieves heat dissipation and demisting functions inside the lamp due to the fact that temperature difference inside the lamp is decreased, is simple in structure and low in manufacture cost, and service performance of the lamp is enhanced.
Description
Technical field
The utility model relates to a kind of heat radiation demister that is used for car light, belongs to the motor vehicle lamp technical field.
Background technology
Automobile lamp mostly adopts bulb as light source at present, and lamp housing, lampshade and speculum etc. are made by plastic material, so have characteristics such as cost is low, weight is light.But automobile lamp can produce a large amount of heats after light source is lighted when work, if heat can not be handled timely and effectively, can influence the service life and the performance of parts on every side.So automobile lamp especially headlight tool all can adopt the radiating mode of different structure, but also exists the radiator structure complicacy, the problem that cost is high.In addition, because the lamp interior lampshade corner far away apart from light source, when the light fixture internal-external temperature difference was big, lamp interior was uneven in temperature in addition, especially can produce fog in the bottom at the periphery of lampshade, and influence the serviceability of light fixture.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, the heat radiation demister that is used for car light that can realize heat radiation and demist airway dysfunction in the light fixture preferably.
The utility model is that the technical scheme that achieves the above object is: a kind of heat radiation demister that is used for car light; It is characterized in that: comprise fan, gang socket and air draft conduit; Described fan is that its air inlet of fan of being connected in the lamp housing of centrifugal fan is corresponding with air vent on the speculum; Gang socket is fixed on the side air-out mouth place of fan; The air inlet of air draft conduit is installed in the gang socket and with the side air-out mouth of fan and communicates, and the air outlet of air draft conduit is positioned at the corner of lampshade bottom.
The heat radiation demister of the utility model adopts fan, gang socket and air draft conduit, and fan is fixed on lamp housing inside, and the air inlet of fan is corresponding with air vent on the speculum; Make the heat that is produced behind the light source igniting through this air vent suction fan,, hot-air is forced to be directed at the corner of lampshade bottom through being connected the air draft conduit in the fan one side gang socket; Owing to can collect hot-air in the light fixture through fan; And lead lower corners place at lampshade, and hot-air is evenly scattered at the lampshade position, reduced the temperature of lamp interior on the one hand apart from the light source closer; Also make the lampshade place far away have certain temperature on the other hand apart from light source; Because the temperature difference of lamp interior reduces, and realizes the heat radiation and the demist airway dysfunction of lamp interior preferably, and is simple in structure; Low cost of manufacture has improved the serviceability of light fixture.
Description of drawings
Below in conjunction with accompanying drawing the embodiment of the utility model is made further detailed description.
Fig. 1 is the structural representation that the utility model is used for the heat radiation demister of car light.
Fig. 2 is the structural representation of the utility model fan.
Fig. 3 is the structural representation of the utility model gang socket.
Wherein: the 1-lamp housing, the 2-bulb, the 3-speculum, the 31-air vent, the 4-fan, the 41-air inlet, 42-side air-out mouth, 5-gang socket, the 51-installing hole, 6-air draft conduit, 7-adorns circle, the 8-lampshade.
The specific embodiment
See shown in Fig. 1～3 that the utility model is used for the heat radiation demister of car light, comprise fan 4, gang socket 5 and air draft conduit 6; The fan 4 of the utility model is a centrifugal fan 4, and fan 4 is bonded in through bonding agent on the madial wall of lamp housing 1, and this fan 4 is arranged on the side near bulb 2; And speculum 3 is provided with air vent 31, and fan 4 its air inlets 41 are corresponding with air vent 31 on the speculum 3, can collect a large amount of hot-airs that bulb 2 is produced in the course of the work at fan 4; Gang socket 5 is installed on the side air-out mouth 42 of fan 4, and for reducing the weight of gang socket 5, the both sides indent of gang socket 5 is the closing in shape; The bottom of gang socket 5 is connected side air-out mouth 42 places of fan 4, and gang socket 5 can be bonded in side air-out mouth 42 places of fan 4 through bonding agent, and the air inlet of air draft conduit 6 is installed in the gang socket 5 and with the side air-out mouth 42 of fan 4 and communicates; This gang socket 5 is provided with installing hole 51; Air draft conduit 6 is pegged graft or is bonded in the installing hole 51 in the gang socket 5, and the air outlet of air draft conduit 6 is positioned at the corner of lampshade bottom, sees shown in Figure 1; The air outlet of air draft conduit 6 is positioned at the edge of decorations circle 7 far-ends; Lampshade 8 is installed on the lamp housing 1, and the edge of its decorations circle 7 far-ends promptly is positioned at the corner of lampshade 8, therefore can the heat that light source produced be forced to lead the position that light fixture is prone to produce fog through fan 4 and air draft conduit 6; To the effect that light fixture reaches heat radiation simultaneously and removes fog, improved the serviceability of light fixture.
