The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further.

As shown in Figure 1, a kind of Down lamp comprises lamp body 10 and diffusion shell 11, and described diffusion shell 11 is contained in described lamp body 10, and described lamp body 10 is provided with buckle 100, and described diffusion shell 11 is provided with button bit 110, and described buckle 100 matches with described button bit 110.By in lamp body 10 inside buckle 100 being set, at diffusion shell 11 button bit 110 is set, buckle 100 is matched with button bit 110, described diffusion shell 11 is fixed, phenomenon can not appear rocking etc. in use; Described buckle 100 is arranged on lamp body 10 inside, so the bearing that buckle 100 cooperates with button bit 110 is not exposed to lamp body 10 appearances in lamp body 10 inside, simultaneously, can't see screw in lamp body 10 appearances, can not influence visual effect.

As Fig. 2, shown in Figure 3, described buckle 100 can be that described button bit 110 can be the breach that is arranged at described diffusion shell 11 outer rims in the described lamp body 10 inner projectioies that arrange, described breach and described projection coupling.When fixing diffusion shell 11, diffusion shell 11 is inserted lamp body 10 inside, make the projection of lamp body 10 inside corresponding with the gap position of diffusion shell 11, be convenient to place diffusion shell 11; Projection is reserved with diffusion shell 11 holddown grooves with lamp body 10, and when diffusion shell 11 was placed into the pre-determined constant groove, rotation diffusion shell 11 staggered projection and gap position, and fixedly diffusion shell 11, and is simple to operate, good fixing effect, and can not influence visual effect.

Perhaps, described buckle 100 can be that projection is scalable in the described lamp body 10 inner projectioies that arrange, and described button bit 110 can be described diffusion shell 11 outer rims.Described projection is scalable, and when being squeezed, projection can be compressed into lamp body 10 and not protrude; After extruding was eliminated, projection was extended and protrudes from lamp body 10.Under the telescopic situation of projection, diffusion shell 11 can not need to arrange breach.When fixing diffusion shell 11, diffusion shell 11 is inserted lamp body 10 inside, projection is reserved with diffusion shell 11 holddown grooves with lamp body 10, be placed in the process of pre-determined constant groove at diffusion shell 11, diffusion shell 11 first expression lobes make protruding indentation lamp body 10, do not continue motion and do not influence diffusion shell 11; After diffusion shell 11 was placed into predetermined holddown groove, described projection was stretched out, and protruded from lamp body 10, thereby blocked diffusion shell 11, and diffusion shell 11 can not be returned along route is installed.Simple to operate, good fixing effect, and can not influence visual effect.

Certainly, the locate mode that described buckle 100 matches with button bit 110 can also be in described diffusion shell 11 outer rims groove shape button bit 110 to be set, and in lamp body 10 inside pivotable buckle 100 is set, and described buckle 100 fastens with button bit 110.Simple in structure, it is convenient to implement.

Described lamp body 10 inside are provided with 2 the above buckles 100.2 above buckles 100 cooperate with the button bit 110 of corresponding number, can make fixed effect better.

2 the above buckles 100 are evenly arranged in described lamp body 10.Buckle 100 is evenly arranged in lamp body 10, can make diffusion shell 11 stressed even, makes locating effect better, simultaneously, makes the stressed also more even of buckle 100, avoids wherein certain buckle 100 stressed fatigue, orients the present situation condition.

As shown in Figure 4, among embodiment, it also comprises heat-conducting substrate assembly 12 and fixed support 13 therein, and described lamp body 10 and heat-conducting substrate assembly 12 are fixing with described fixed support 13 successively; Described heat-conducting substrate assembly 12 fits in described fixed support 13, and fixes by screw.But fixed support 13 is Heat Conduction Material, and described heat-conducting substrate assembly 12 is fitted with fixed support 13 and be fixing, makes Down lamp luminous and heat that produce can pass through fixed support 13 heat conduction, and looses to the outside.

Described heat-conducting substrate assembly 12 is LED aluminium base assembly, and described fixed support 13 is black, is formed by anodic oxidation, described LED aluminium base assembly and the fixed support 13 fixing first radiator modules that form.The thermal diffusion performance of LED aluminium base assembly is good, and the life-span is long, and cost is low; Described fixed support 13 is through anodic oxidation, and is made into black, makes the fixed support 13 itself can heat loss through radiation, and by the heat loss through radiation of fixing support itself, junction temperature can reduce more than 10 °.LED aluminium base assembly and fixed support 13 are fixing can to form the first radiator module, and the heat radiation electrical power of the first radiator module can reach 8W, simple in structure, good heat dissipation effect.

As shown in Figure 5, in another embodiment, it also comprises radiator 14, and described radiator 14 fits in described fixed support 13; Described LED aluminium base assembly, fixed support 13 and radiator 14 fixing second radiator, 14 modules that form.Fixed support 13 is through anodic oxidation, and is made into black, makes the fixed support 13 itself can heat loss through radiation, and the heat loss through radiation by fixing support itself can reduce the Down lamp temperature.The radiator 14 of fitting with fixed support 13 is set again, can forms second radiator, 14 modules, the heat radiation electrical power of second radiator, 14 modules is increased.The power of radiator 14 can be 15W, and described second radiator, 14 modules can form 15W radiator 14 modules, good heat dissipation effect; Certainly, the power of radiator 14 can also be other, as 20W, 25W etc., arranges as required.

In the present embodiment, Down lamp mainly can be the LED Down lamp, described lamp body 10, diffusion shell 11, heat-conducting substrate assembly 12, fixed support 13, radiator 14 are fixing successively, and described lamp body 10 and described fixed support 13 are fixed by screw, heat-conducting substrate assembly 12 places between lamp body 10 and the described fixed support 13, and fixing by screw and fixed support 13.

The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
