All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The lamp assembly and the lighting lamp provided by the utility model are described below with reference to fig. 1-6.

Referring to fig. 1, the lamp assembly of the present utility model includes a lamp 1 and a heat dissipation structure 2 mounted on the lamp 1. The heat dissipation structure 2 comprises a protection outer frame 21 and at least one layer of graphene sheets 22, wherein the protection outer frame 21 is a frame structure, and the at least one layer of graphene sheets 22 are positioned in the protection outer frame 21 and fixed on the surface of the lamp body of the lamp 1 through the protection outer frame 21.

Specifically, the lamp 1 includes a lamp body 101, a lamp body inner functional part 102, a light source assembly 103, a lens 104, an adapter 105, a face ring 106, a clip spring 107, and a reflector 108, and the lamp body inner functional part 102, the light source assembly 103, the lens 104, the adapter 105, the face ring 106, the clip spring 107, and the reflector 108 are sequentially mounted on the lamp body 101.

Referring to fig. 2, the protective outer frame 21 includes a bottom surface 211 and a side wall 212, and the bottom surface 211 and the side wall 212 enclose a cavity with one open end for placing the graphene sheets 22. Wherein at least one of the bottom surface 211 and the side wall 212 is provided with a mesh 210 communicating with the outside.

The mesh holes 210 are used for convection heat dissipation, and dissipate heat absorbed by the graphene sheets 22. The mesh holes 210 may be provided only on the bottom surface 211 or the side walls 212. Preferably, mesh openings 210 are provided in both bottom surface 211 and side walls 212 to dissipate as much heat as possible.

The shape of mesh 210 may be circular, square, diamond, rectangular, or other polygonal shape, without limitation.

Further, at least one upright 213 is disposed in the cavity of the protective outer frame 21, each upright 213 is vertically disposed on the bottom 211, and the protective outer frame 21 is mounted on the lamp body 101 through the upright 213.

Further, each upright 213 is provided with a first mounting hole 2130 disposed along the axial direction of the upright 213, and the first mounting hole 2130 extends from the end surface of the upright 213 far from the bottom surface 211 toward the inside of the upright 213, so that the protection frame 21 is detachably connected to the lamp body 101 through the first mounting hole 2130.

Wherein the height of each upright 213 is equal to the depth of the cavity, i.e., the end surface of each upright 213 is flush with the end surface of the sidewall 212, thereby facilitating the installation of the protective outer frame 21.

Specifically, in the present embodiment, 4 columns 213 are disposed in the cavity of the protection frame 21, and the 4 columns 213 are distributed around the bottom 211.

With continued reference to fig. 1, a surface of the lamp body 101 facing the heat dissipation structure 2 (i.e., the bottom 1011 of the lamp body 101) is provided with second mounting holes 1010 corresponding to the first mounting holes 2130 one by one, and the second mounting holes 1010 penetrate through the bottom 1011 of the lamp body 101. The lamp body 101 and the heat dissipation structure 2 are detachably connected through a fastener, wherein one end of the fastener penetrates into the first mounting hole 2130 from the second mounting hole 1010, so that the heat dissipation structure 2 is mounted on the lamp body 101 of the lamp.

In one embodiment, the fastener may be, but is not limited to, a screw 3.

Referring to fig. 3, each layer of graphene sheet 22 in the present embodiment is provided with a through hole 221 corresponding to the upright post 213, the aperture of the through hole 221 is larger than that of the upright post 213, and the upright post 213 can be installed on the surface of the lamp body 101 through the through hole 221 on the graphene sheet 22. Wherein the through holes 221 penetrate the upper and lower surfaces of the graphene sheet 22, and the number of through holes 221 corresponds to the number of the pillars 213, and the positions of the through holes 221 also correspond to the positions of the pillars 213.

Further, a plurality of heat dissipation holes 222 are further formed in each layer of the graphene sheet 22, the heat dissipation holes 222 and the through holes 221 are arranged at intervals, and the heat dissipation holes 222 penetrate through the upper surface and the lower surface of the graphene sheet 22. The heat dissipation holes 222 are beneficial to the heat dissipation of the graphene sheets 22, so that the heat dissipation holes 222 can be uniformly distributed on the graphene sheets 22.

In the present embodiment, the aperture of the heat dissipation hole 222 is smaller than that of the through hole 221, which is not limited to this, and the apertures of the heat dissipation hole 222 and the through hole 221 can be set according to practical requirements. It should be noted that, since the graphene sheet 22 has excellent heat conduction performance (transverse heat conductivity reaches 1500w/m.k, and the lateral heat conductivity reaches 95-200 w/m.k of the far-reaching aluminum piece), the aperture of the heat dissipation hole 222 is not too large, so that the heat conduction effect of the graphene sheet 22 is not affected.

Wherein, the thickness of each layer of graphene sheets 22 is 0.025mm-0.3mm. Illustratively, the thickness of the single-layer graphene sheets 22 may be 0.05mm, 0.1mm, 0.2mm, or 0.25mm. The thickness of the graphene sheet 22 can be made into an ultrathin sheet according to actual requirements so as to adapt to some special use scenes. If the actual lifting height of the ceiling (the distance between the ceiling and the cement wall surface) is short, the lamp needs to be ultrathin at this time, and the graphene sheets 22 can be used for heat dissipation so as to reduce the height of the lamp.

Referring to fig. 4, in order to achieve a better heat dissipation effect, a mode of stacking multiple graphene sheets 22 may be adopted, and the specific number of layers of the graphene sheets 22 may be determined according to the heat dissipation requirement. Wherein, a plurality of heat dissipation holes 222 and a plurality of through holes 221 are all arranged on the multilayer graphene sheet 22, and the heat dissipation holes 222 on the multilayer graphene sheet 22 are arranged in a one-to-one correspondence manner, and the through holes 221 on the multilayer graphene sheet 22 are also arranged in a one-to-one correspondence manner. Therefore, the upright post 213 of the outer frame 21 can conveniently and smoothly pass through the through hole 221 on the multi-layer graphene sheet 22 to be connected with the lamp body, and the heat dissipation channel can be formed after the heat dissipation holes 222 on the multi-layer graphene sheet 22 are overlapped, so that the heat dissipation of the inner-layer graphene sheet 22 is facilitated.

Further, the shape and thickness of the multi-layered graphene sheet 22 are the same.

The graphene sheet 22 can be cut into various shapes and sizes according to the shape of the lamp body by utilizing the easy cutting property of the graphene sheet 22.

Referring to fig. 1 and 5, the opening end of the protective frame 21 is fixed on the lamp body 101 toward one side of the lamp body 101, wherein, when the protective frame 21 is installed, the graphene sheets 22 are closely attached to each other, wherein one graphene sheet 22 close to the bottom 211 is attached to the bottom 211, and one graphene sheet 22 close to the lamp body 101 is attached to the bottom 1011 of the lamp body 101. Specifically, the screw 3 passes through the second mounting hole 1010 on the lamp body 101 and is screwed into the first mounting hole 2130 of the upright post 213, and by means of the locking screw 3, the protection outer frame 21 approaches to one side of the lamp body 101, and meanwhile, the graphene sheet 22 is compressed tightly, so that the graphene sheet 22 is tightly attached to the bottom 1011 of the lamp body 101, and the heat dissipation effect of the graphene sheet 22 is increased.

Referring to fig. 6, the present utility model further provides a lighting fixture, which includes the above-mentioned fixture assembly. The lighting fixture comprises a light source assembly 103 positioned inside a lamp body 101, wherein the light source assembly 103 is arranged close to the bottom 1011 of the lamp body 101. The light source assembly 103 is used for emitting light, but generates a certain amount of heat while emitting light. Therefore, the heat dissipation structure 2 is disposed on the outer side of the lamp body 101 in the present embodiment, and the heat dissipation structure 2 is disposed opposite to the light source assembly 103 and detachably mounted on the bottom 1011 of the lamp body 101, so that the heat generated by the light source assembly 103 can be rapidly absorbed.

Specifically, the structure of the lamp assembly in this embodiment is the same as that of the lamp assembly in the above embodiment, and specific reference is made to the description in the above embodiment, which is not repeated here.

According to the utility model, the graphene sheets with high heat conductivity are adopted to replace the current common aluminum die-casting material, so that the graphene sheets can be smaller than the aluminum material in the same heat dissipation requirement, and the advantage of using the graphene sheets is obvious under the condition that the size of the lamp is limited. According to the fact that the heat dissipation structure has the same height, the efficiency of the heat dissipation structure is improved by more than 40% compared with that of an aluminum part. With the same heat dissipation capacity, the height of the heat dissipation structure of the utility model can be reduced by about 30% compared with the thickness of the aluminum piece heat dissipation structure.

In addition, the protection outer frame with the frame body structure can protect the graphene sheet in all directions, so that the damage to the graphene sheet in the transportation and use processes of the lamp is avoided; and the graphene sheet can be fixedly arranged on the surface of the lamp body of the lamp through the protection outer frame, and only the protection outer frame and the lamp body are required to be fixed, so that the assembly is simple, and the problems that the graphene sheet is extremely easy to damage and difficult to assemble when the graphene sheet is used on the lamp can be solved.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present utility model.
