Description
Technical field
The utility model relates to a kind of Down lamp, especially a kind of LED down.
Background technology
Present Down lamp on the market, because the structure of himself can not shed the heat produced while LED lamp bead luminescence timely timely, cause LED lamp bead chip to be in the environment of high temperature to work always, not only accelerate the light decay of LED lamp bead, and greatly reduce working life.
Utility model content
The purpose of this utility model is to provide a kind of LED down, solves the problems such as existing LED down heat radiation, achieves the object of LED down high life low light attenuation.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of LED down, comprise shell and power supply, shell comprises lamp cylinder, radiating fin and aluminium lamination, radiating fin is arranged on lamp drum outer wall and inclined design, aluminium lamination is wrapped in outside radiating fin, gap is provided with between aluminium lamination and lamp cylinder bottom outer edge, LED lamp bead is provided with in shell, LED lamp bead and shell are fitted by heat-conducting silicone grease, LED lamp bead is electrically connected by wire with power supply, outer casing bottom opening part is provided with frosted panel, frosted panel has face shield, face shield is provided with two springs, face shield is provided with groove, groove is provided with the buckle matched with it, shell, face shield, frosted panel is fixed by buckle and groove, the design of radiating fin inclination and aluminium lamination, not only increase the contact area with air, strengthen overall thermal radiation, and radiating fin, aluminium lamination and gap define the passage that a rule tilts, strengthen convection effects.
Be preferably, the groove on face shield is four, and structure is simple, and overall buckle is fixedly connected with fastening.
Be preferably, LED lamp bead is COB lamp pearl, reduces overall thermal resistance, improves heat-sinking capability.
Be preferably, power supply is external power supply, reasonable in design, reduces the heat of LED lamp bead generation to the infringement of power supply.
The beneficial effects of the utility model are: the design of the inclination of the utility model radiating fin and aluminium lamination, not only increase the contact area with air, strengthen overall thermal radiation, and radiating fin, aluminium lamination and gap define the passage of a rule inclination, strengthen convection effects.
Accompanying drawing explanation
Fig. 1 is profile of the present utility model;
Wherein: 1, power supply, 2, lamp cylinder, 3, radiating fin, 4, aluminium lamination, 5, gap, 6, LED lamp bead, 7, frosted panel, 8, face shield, 9, groove, 10, buckle, 11, wire, 12, spring
Detailed description of the invention
In order to understand the utility model further, below in conjunction with accompanying drawing, the utility model is described.
As shown in Figure 1, a kind of LED down that the present embodiment provides, comprise shell and power supply 1, shell comprises lamp cylinder 2, radiating fin 3 and aluminium lamination 4, radiating fin 3 is arranged on lamp cylinder 2 outer wall and inclined design, aluminium lamination 4 is wrapped in outside radiating fin 3, gap 5 is provided with between aluminium lamination 4 and lamp cylinder 2 bottom outer edge, COB lamp pearl 6 is provided with in shell, COB lamp pearl 6 and shell are fitted by heat-conducting silicone grease, COB lamp pearl 6 is connected by wire 11 with external power supply 1, outer casing bottom opening part is provided with frosted panel 7, frosted panel 7 has face shield 8, face shield 8 is provided with two springs 12, face shield 8 is provided with four grooves 9, groove 9 place is provided with the buckle 10 matched with it, shell, face shield 8, frosted panel 7 is fixed by buckle 10 and groove 9.
Radiating fin inclination and the design of aluminium lamination, not only increase the contact area with air, strengthen overall thermal radiation, and radiating fin, aluminium lamination and gap define the passage of a rule inclination, strengthen convection effects.
These are only preferred embodiment of the present utility model; it should be pointed out that for the ordinary skill in the art, do not departing under principle prerequisite of the present utility model; can also make various deformation and improvement, this also should be considered as protection domain of the present utility model.
