Description
Technical field
The utility model relates to a kind of high thermally conductive LED shot-light.
Background technology
Traditional LED shot-light scatters after the last heat of LED is difficult to, thereby has accelerated the light decay of LED, has had a strong impact on the LED life-span.
The utility model content
The utility model purpose is: to the problems referred to above, a kind of high thermally conductive LED shot-light is provided, this LED shot-light thermal diffusivity is good, long service life.
The technical scheme of the utility model is: a kind of high thermally conductive LED shot-light; Comprise lamp socket, driving power, lens, lamp plate and be welded in the LED on the lamp plate; This high thermally conductive LED shot-light comprises that also one is installed in the radiator on the said lamp socket; Be formed with a cavity volume between this radiator and the lamp socket, said driving power is installed in this cavity volume; Said radiator is made up of the Aluminum Drum high heat-conducting plastic shell outer with wrapping in this Aluminum Drum, and said lamp plate is installed in the Aluminum Drum, and said lens are installed on the lamp plate and with radiator and are fixed.
As preferably, be provided with heat conductive silica gel between said lamp plate and the Aluminum Drum.
As preferably, all link to each other between said radiator and the lamp socket and between radiator and the lamp plate through screw.
As preferably, said LED has one.
As preferably, said LED has two or three, and these LED are connected in series.
The utility model has the advantages that: the utility model has installed a radiator additional at the LED shot-light, and the described radiator of this radiator is made up of the Aluminum Drum high heat-conducting plastic shell outer with wrapping in this Aluminum Drum.The last heat of LED can be delivered on the high heat-conducting plastic shell through Aluminum Drum fast, because the heat loss through radiation of high heat conduction engineering plastics is very capable, and thermal resistance is very little, thereby greatly reduces the temperature of this LED shot-light.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to introduce:
Fig. 1 is the stereogram of the utility model embodiment;
Fig. 2 is the explosive view of the utility model embodiment;
Wherein: 1 is lamp socket, and 2 is driving power, and 3 is lens, and 4 is lamp plate, and 5 is LED, and 6 is radiator, and 6-1 is an Aluminum Drum, and 6-2 is high heat-conducting plastic shell.
The specific embodiment
As depicted in figs. 1 and 2; The high thermally conductive LED shot-light of present embodiment comprises lamp socket 1, driving power 2, lens 3, lamp plate 3 and is welded in the LED4 on the lamp plate; Wherein LED4 has three and these three LED and is connected in series that (LED also can be arranged to one or two; When LED is two, also be connected in series between these two LED).
This high thermally conductive LED shot-light comprises that also one is installed in radiator 6 on the said lamp socket 1 (radiator with lamp socket between be connected through screw).Be formed with a cavity volume between radiator 6 and the lamp socket 1, said driving power 2 is installed in this cavity volume.
This radiator 6 constitutes (forming through injection mo(u)lding) by the Aluminum Drum 6-1 high heat-conducting plastic shell 6-2 outer with wrapping in this Aluminum Drum, and Aluminum Drum fully combines with high heat-conducting plastic shell.Said lamp plate 4 is installed in the Aluminum Drum 6-1 (lamp plate with radiator between be connected through screw), can be delivered to rapidly on the Aluminum Drum 6-1 in order to guarantee the heat on the lamp plate 4, and this example also is provided with heat conductive silica gel between lamp plate 4 and Aluminum Drum 6-1.
Said lens 3 are installed on the lamp plate 4, and these lens 3 are fixed with radiator 7.
In this example, radiator 6 is made up of the Aluminum Drum 6-1 high heat-conducting plastic shell 6-2 outer with wrapping in Aluminum Drum, and Aluminum Drum fully combines with high heat-conducting plastic shell.During work; The last heat of LED5 is delivered on the Aluminum Drum 6-1 by lamp plate 4, is delivered to apace on the high heat-conducting plastic shell 6-2 by Aluminum Drum 6-1 again, and the thermal conductivity of high heat-conducting plastic shell 6-2 can reach more than the 10W/m.K; And thermal resistance is little, thereby greatly reduces the temperature of this LED shot-light.And radiator 6 is selected the good high heat-conducting plastic shell of insulating properties for use, has not only reduced the weight of radiator, and the safety coefficient of lamp is greatly improved, and has reduced Danger Electric shock risk.
Certainly, the foregoing description only is the technical conceive and the characteristics of explanation the utility model, and its purpose is the content that lets people can understand the utility model and implements according to this, can not limit the protection domain of the utility model with this.All equivalent transformation or modifications of doing according to the spirit of the utility model main technical schemes all should be encompassed within the protection domain of the utility model.
