The specific embodiment

The following stated is merely the preferred embodiment of the utility model, does not therefore limit the protection domain of the utility model.

Embodiment, see that Fig. 1 is to shown in Figure 3:

The utility model is a kind of Down lamp of easy disassembly; Comprise the shell 10, prefocus cup 30 and the light source module 20 that fit together successively; It is characterized in that the joint pin 29 on the said light source module 20 is stuck in " L " shape fluting 31 on said prefocus cup 30 upper surfaces; The flange 32 of said prefocus cup 30 lower surfaces is positioned on the inboard step 11 in said shell 10 bottom surfaces, and shell 10 is provided with the shell fragment 40 of below buckle portion 41, the flange 32 that the hook portion 41 of said shell fragment 40 and said step 11 grasp said prefocus cup 30.The utility model is designed to shell 10, prefocus cup 30 and light source module 20 with Down lamp and fits together successively, and the joint pin on the light source module 20 29 snaps in " L " shape fluting 31 on said prefocus cup 30 upper surfaces; The flange 32 of prefocus cup 30 lower surfaces is positioned on the inboard step 11 in said shell 10 bottom surfaces, and shell 10 is provided with the shell fragment 40 of below buckle portion 41, the flange 32 that the hook portion 41 of said shell fragment 40 and said step 11 grasp said prefocus cup 30.Through this kind structure; Syndeton between three parts of Down lamp is very simple; When dismounting, joint pin 29 is withdrawed from just and can light source module 20 be pulled down in L shaped fluting 31, the hook portion 41 of shell fragment 40 is pushed aside just and can prefocus cup 30 be taken out in shell 10; Otherwise assembling only need snap in the joint pin 29 of light source module 20 in the L shaped fluting 31 time, prefocus cup 30 is inserted shells 10 and puts in place get final product.No matter therefore be that dismounting or assembling are all very convenient; When needs are changed different assembly; Even need not use other any instrument and just can manually accomplish dismounting and assembling, when producing products of different specifications in batches, make the production process of the different Down lamps simple and fast that becomes; Can also save the design production cost, promote the advantage of production efficiency.
