Specific embodiment

Core of the present utility model is to provide a kind of lamp body, efficiently solves the leakage problem of lamp body；The utility model Another core be to provide a kind of Down lamp including above-mentioned lamp body.

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Embodiment in based on the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment for being obtained, belongs to the scope of the utility model protection.

Fig. 1 to Fig. 4 is refer to, the structure of the lamp body that Fig. 1 is provided by a kind of specific embodiment in the utility model is shown It is intended to；Front views of the Fig. 2 for Fig. 1；The structure of the lamp body that Fig. 3 is provided by another kind of specific embodiment in the utility model is shown It is intended to；Front views of the Fig. 4 for Fig. 3.

In a kind of specific embodiment, lamp body provided by the utility model, including framework 1 and back shroud 2, light source is pacified Loaded on framework 1, there is opening, back shroud 2 to be installed on opening on the top of framework 1, for encapsulating opening.Back shroud 2 and framework 1 It is detachably connected, convenient maintenance, replacing part.There is 1 side wall end of framework seam, back shroud 2 to be abutted against with seam step surface, The gap that 2 outward flange of back shroud is engaged place with 1 side wall of framework is eliminated by the step surface of seam namely, is not had between the two Direct gap, that is, without loophole.After light fixture is lighted, light cannot spill, and without light leakage phenomena, distribute complete luminous from front Hole sends, and will not spill from the back side, and light does not lose, and whole luminous flux is added, and increases brightness, and preferably, light is more equal for whole light effect Even.

Above-mentioned lamp body is only a kind of preferred version, is specifically not limited thereto, and can do according to actual needs on this basis Provide and targetedly adjust, so as to obtain different embodiments, 1 side wall end of framework has recessed seam 3, in back shroud 2 It is embedded in the groove of recessed seam 3, the outward flange of back shroud 2 is connected at the inwall of recessed seam 3, that is, the size of back shroud 2 Identical with the size of groove, back shroud 2 is just installed in groove.By the step surface of recessed seam 3 by back shroud 2 and framework 1 Cooperation gap shielding, light can not be spilt from the back side, increase the light efficiency of light fixture；Meanwhile, recessed seam 3 is opened in the side of framework 1 Wall end, the structure of back shroud 2 are identical with prior art, and without the need for changing, workload is less, and overall structure is relatively simple, recessed Seam 3 is easy to process.

On the basis of above-mentioned specific embodiment, those skilled in the art can be according to the difference of concrete occasion, to lamp Body carries out some changes, and the end face of framework 1 is concordant with the end face of back shroud 2, without corner angle, more smooth, it is easy to install, more Attractive in appearance.Certainly, the end face of framework 1 concordant with the end face of back shroud 2 simply a kind of preferred embodiment, be not unique, Can not also concordantly, the end face of such as framework 1 is higher than the end face of back shroud 2, can reduce the thickness of back shroud 2, mitigates weight.

Obviously, under the guidance of this thought, those skilled in the art can be according to the difference of concrete occasion to above-mentioned Specific embodiment carries out some changes, and the outward flange that 1 side wall end of framework has male half coupling, back shroud 2 has and male half coupling The reverse male half coupling being engaged, now back shroud 2 be placed on framework 1, back shroud 2 is completely covered the recessed of framework 1 equivalent to end cap Seam 3, male half coupling are engaged with reverse male half coupling, can not only block the gap between back shroud 2 and framework 1, are reduced light and are damaged Lose；Back shroud 2 and framework 1 can also be accurately positioned, it is easy to correct installation.

It is important to note that lamp body provided by the utility model is not intended to be limited to this kind of situation, outside framework 1 Wall is concordant with the outer wall of back shroud 2, and junction does not have corner angle, more smooth, it is easy to install, and is difficult to scratch installation personnel, more Attractive in appearance.

Lamp body provided by the utility model, in the case of other parts are immovable, the step surface width of seam is 5mm To the numerical value between 10mm, including 5mm and 10mm, concrete width is unrestricted, can be according to practical situations depending on, step Face is wider, that is, back shroud 2 is larger with the overlapping area of framework 1, and shaded effect is preferable.

For the lamp body in each embodiment above-mentioned, back shroud 2, is such as connected by screw thread for being detachably connected with framework 1 Connect, easy to connect, it is easy to dismantle.Screwed hole on back shroud 2 and framework 1 is opened in stop portion, the bonnet at screwed hole place Plate 2 and the more seam of framework 1, are combined as a whole with seam, and intensity is larger, more solid, and security is higher, service life compared with Long.

In order to further optimize above-mentioned technical proposal, lamp body can be installed on by the mounting bracket 4 being installed on framework 1 On ceiling, it is also possible to be installed on ceiling by the jump ring 5 on framework 1, simple structure is easy for installation, can also be passed through Other suitable modes are installed, which kind of mounting means specifically used, can be according to the different sets itselfs of specifically used situation, all In protection domain of the present utility model.

Based on the lamp body provided in above-described embodiment, the utility model additionally provides a kind of Down lamp, and the Down lamp includes lamp body And the light source being installed on lamp body, wherein lamp body is any one lamp body in above-described embodiment.As the Down lamp is employed The lamp body in embodiment is stated, so the beneficial effect of the Down lamp refer to above-described embodiment.

In this specification, each embodiment is described by the way of going forward one by one, and what each embodiment was stressed is and other The difference of embodiment, between each embodiment identical similar portion mutually referring to.

The foregoing description of the disclosed embodiments, enables professional and technical personnel in the field to realize or new using this practicality Type.Multiple modifications of these embodiments will be apparent for those skilled in the art, determined herein The General Principle of justice can be realized in the case of without departing from spirit or scope of the present utility model in other embodiments.Cause This, the utility model is not intended to be limited to the embodiments shown herein, and is to fit to and principles disclosed herein The most wide scope consistent with features of novelty.
