Abstract
The utility model provides a vehicle-mounted LED lamp. The vehicle-mounted LED lamp is characterized by comprising a heat radiation casing, wherein the heat radiation casing comprises five side walls arranged in a circling manner; the five side walls are encircled to form a first cavity with one end opened; radiating fins are arranged on the outer surface of the heat radiation casing; the opening of the first cavity is fixedly connected with a front cover through a sealing washer to be sealed; LED components and reflective cups are sequentially arranged in the first cavity; the LED components are fixedly connected with the inner surface of the heat radiation casing; a second cavity for injecting a cooling liquid is formed in the side walls; a water inlet and a water outlet are formed in the second cavity and communicated with an external cooling liquid pipeline to form a circulatory radiating structure. Through the above scheme that the cavity is formed in the side walls of a traditional heat radiation casing and the cavity is filled with cooling liquid, owing to the property of big specific heat capacity of the cooling liquid, heat can be taken away timely, so that the radiating effect is improved and the service life of the LED components is prolonged.
Description
Technical field
The utility model relates to lighting field, refers to especially a kind of vehicle-mounted LED lamp.
Background technology
At present, along with people are to environmental protection, energy-conservation more and more attention, the application popularization of LED is also more and more extensive.Automotive lighting is with lamp because its work under bad environment and requirement that intensity of illumination, optically focused performance and floodlight are penetrated to aspect, and LED cannot be competent at, so use xenon lamp in the quite a long time always.
Based on this, someone proposes a kind of automobile LED illuminating lamp, changes the luminescence component on orthodox car illuminating lamp into LED lamp by xenon lamp, and between face shield and reflector, sealing ring is set, thereby makes LED assembly can be competent at the severe condition of work of lamp for automotive lighting.But this mode has but caused LED under sealing condition, thereby temperature sharply raises and makes the light dimmed problem of turning to be yellow.
Utility model content
The utility model proposes a kind of vehicle-mounted LED lamp, solved the problem of the not good easy initiation light flavescence obfuscation of radiating effect in prior art.
The technical solution of the utility model is achieved in that
A kind of vehicle-mounted LED lamp, comprise: heat-dissipating casing, described heat-dissipating casing comprises around five sidewalls that arrange, described five sidewalls are provided with the first cavity of an end opening around formation, described heat-dissipating casing outer surface is provided with radiating fin, described the first cavity opening part is fixedly connected with protecgulum by seal gasket and forms sealing, in described the first cavity, be provided with successively LED assembly and reflector, described LED assembly is fixedly connected with heat-dissipating casing inner surface, in described sidewall, be provided with for injecting the second cavity of cooling fluid, described the second cavity is provided with water inlet and delivery port, described water inlet and described delivery port are communicated with formation cyclic cooling structure with extraneous cooling fluid pipeline.
Further, described LED assembly comprises that aluminium base and array be located at the LED lamp pearl on described aluminium base surface.
Further, described reflector is a plurality of, and corresponding described LED lamp pearl is array distribution.
Further, described a plurality of reflectors are integrated to manufacture and form, and are fixedly connected with described heat-dissipating casing by screw thread.
Further, described LED assembly is also electrically connected with the firm power protective device for the protection of described LED assembly.
The beneficial effects of the utility model are: pass through such scheme, to in the sidewall of traditional heat-dissipating casing, cavity be set, cooling fluid is poured in cavity, utilize the large specific heat capacity characteristic of cooling fluid to take away in time heat, thereby improved radiating effect, extended LED assembly service life.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the blast structural representation of an embodiment of a kind of vehicle-mounted LED lamp of the utility model;
Fig. 2 is the heat-dissipating casing part sectional structure schematic diagram of vehicle-mounted LED lamp shown in Fig. 1.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
An embodiment referring to a kind of vehicle-mounted LED lamp of the utility model shown in figure, comprising: heat-dissipating casing 5, protecgulum 1, sealing ring, LED assembly 4 and reflector 3.Described heat-dissipating casing 5 comprises around five sidewalls that arrange, described five sidewalls are provided with the first cavity 52 of an end opening around formation, described heat-dissipating casing 5 outer surfaces are provided with radiating fin 51, and described the first cavity 52 opening parts are fixedly connected with protecgulum 1 by seal gasket 2 and form sealing.
In described the first cavity 52, be provided with successively LED assembly 4 and reflector 3, described LED assembly 4 is fixedly connected with heat-dissipating casing 5 inner surfaces, in described sidewall, be provided with for injecting the second cavity 53 of cooling fluid, described the second cavity 53 is provided with water inlet and delivery port, and described water inlet and described delivery port are communicated with formation cyclic cooling structure with extraneous cooling fluid pipeline.
By such scheme, will in the sidewall of traditional heat-dissipating casing 5, cavity be set, cooling fluid is poured in cavity, utilize the large specific heat capacity characteristic of cooling fluid to take away in time heat, thereby improved radiating effect, extended 4 service lifes of LED assembly.
As the further optimization to the present embodiment, described LED assembly 4 comprises that aluminium base and array be located at the LED lamp pearl on described aluminium base surface.Described reflector 3 is a plurality of, and corresponding described LED lamp pearl is array distribution.Described a plurality of reflector 3 is integrated to manufacture and forms, and is fixedly connected with described heat-dissipating casing 5 by screw thread.The LED lamp pearl of a plurality of array distribution, and by the even divergent rays of a plurality of reflectors 3, improved the utilization rate of light, and, integrally manufactured reflector 3 is than the reflector 3 of single reflector 3 or some independent manufactures, also there is certain heat sinking function, extended the service life of a kind of vehicle-mounted LED lamp of the utility model.
