[0002] In the market, full reflection light-emitting lamps are increasingly favored by consumers because they can effectively solve problems such as glare. Full reflection light-emitting lamps include a radiator and a reflective module arranged in the radiator. The radiator is provided with a lamp arm for mounting a light source.

Therefore, the cost for manufacturers to produce different total reflection lamps is relatively high; 2. When the total reflection lamp is in lighting operation, the reflective concave surface has a high temperature due to the direct irradiation of the light source, which will greatly affect the service life of the total reflection lamp.

[0033] Reference Figures 1 to 5 The embodiment of the utility model is a total reflection light emitting lamp, which includes a main heat sink 100, an auxiliary heat sink 200 and a reflective module 300.

[0034] The main radiator 100 is provided with a first cavity 110, and the first cavity 110 has a light outlet 111 arranged upward and an inlet 112 arranged downward. The inner cavity wall of the first cavity 110 is provided with a lamp arm 113, and a light source is provided on the side of the lamp arm 113 away from the light outlet 111. The auxiliary radiator 200 is provided with a second cavity 210, and the auxiliary radiator 200 is arranged at the bottom of the main radiator 100. The second cavity 210 is connected with the first cavity 110 to form an accommodating cavity S1. The reflective module 300 is arranged on the auxiliary radiator 200 and is located in the accommodating cavity S1. The reflective module 300 is provided with a reflective concave surface 310. The light source and the reflective concave surface 310 are arranged up and down, and the light emitted by the light source is reflected by the reflective concave surface 310 and then emitted toward the light outlet 111.

[0035] It is understandable that the materials of the main radiator 100 and the auxiliary radiator 200 can be set to be materials with good heat dissipation properties such as aluminum.

[0036] It is understandable that the reflective module 300 is partially disposed in the first cavity 110 through the insertion opening 112 .

[0037] Through the above structure, the main radiator 100 is set as a universal part, and the manufacturer can assemble and install the main radiator 100 with different auxiliary radiators 200 and reflective modules 300 to obtain different total reflection light-emitting lamps. It can be seen that, on the one hand, the main radiator 100 is universal, so when the manufacturer needs to produce different total reflection light-emitting lamps, the manufacturer does not need to design different main radiators 100 accordingly, so the cost used in producing different total reflection light-emitting lamps can be reduced; on the other hand, the main radiator 100 has better thermal conductivity, so the main radiator 100 can accelerate the heat dissipation in the accommodating cavity S1, thereby extending the service life of the total reflection light-emitting lamp.

[0038] In this embodiment, the auxiliary radiator 200 is detachably connected to the main radiator 100. For details, refer to Figure 2 The main radiator 100 is provided with a first hole 120, and the auxiliary radiator 200 is provided with a second hole 220. The first hole 120 and the second hole 220 are both arranged in the up-down direction, and the first hole 120 and the second hole 220 are threadedly connected with fasteners. The fasteners are arranged as screws or the like.

[0039] Through the above structure, on the one hand, the auxiliary radiator 200 is detachably connected to the main radiator 100, so that the auxiliary radiator 200 and the main radiator 100 can be disassembled, which is convenient for the later maintenance of the reflective module 300; on the other hand, the first hole 120 and the second hole 220 are both arranged in the up and down directions. When the total reflection light-emitting lamp is installed on the ceiling, the opening of the second hole 220 is located above the ceiling, so the user cannot observe the opening of the second hole 220, so as to improve the user's appearance perception of the total reflection light-emitting lamp.

[0040] In some embodiments, the auxiliary heat sink 200 and the main heat sink 100 can be detachably connected via a block buckle hole structure.

[0041] In order to further accelerate the heat dissipation in the accommodating chamber S1, Figure 3 The main heat sink 100 is provided with a first heat dissipation channel 130 connected to the outside, and the inner wall of the first cavity 110 is provided with an opening 114 connected to the first heat dissipation channel 130.

[0042] In this embodiment, refer to Figure 3The height position of the opening 114 is set corresponding to the height position of the reflective concave surface 310.

[0043] Through the above structure, since the height position of the reflective concave surface 310 corresponds to the height position of the opening 114, the hot air generated at the reflective concave surface can enter the first heat dissipation channel 130 through the opening 114 in the first time (quickly) and be discharged to the outside through the first heat dissipation channel 130.

[0044] The first heat dissipation channel 130 is in communication with the outside. For details, refer to Figures 3 to 5 On the one hand, two protrusions 230 are provided on the top of the auxiliary radiator 200, and the protrusions 230 are abutted against the bottom of the main radiator 100. The top of the auxiliary radiator 200, the bottom of the main radiator 100 and the two adjacent protrusions 230 together enclose a heat dissipation space S2, and the heat dissipation space S2 is connected to the outside, and the first heat dissipation channel 130 is connected to the heat dissipation space S2 to communicate with the outside through the heat dissipation space S2; on the other hand, the first heat dissipation channel 130 is arranged in the up-down direction, and the auxiliary radiator 200 is provided with a second heat dissipation channel 240 connected to the outside, the second heat dissipation channel 240 is arranged in the up-down direction, and the second heat dissipation channel 240 runs through the auxiliary radiator 200, the second heat dissipation channel 240 is connected to the first heat dissipation channel 130 through the heat dissipation space S2, and the first heat dissipation channel 130 can also be connected to the outside through the second heat dissipation channel 240.

[0045] Through the above structure, on the one hand, part of the hot air entering the first heat dissipation channel 130 can pass through the heat dissipation space S2 and be discharged to the side of the total reflection light-emitting lamp; on the other hand, part of the hot air entering the first heat dissipation channel 130 can pass through the heat dissipation space S2 and the second heat dissipation channel 240 in sequence and be discharged to the bottom of the total reflection light-emitting lamp; on still another hand, when the total reflection light-emitting lamp is installed on the ceiling, according to the common sense that hot air moves upward, the hot air that is discharged to the bottom of the total reflection light-emitting lamp through the heat dissipation space S2 and the second heat dissipation channel 24 in sequence is located above the ceiling, and its impact on the indoor temperature is relatively small.

[0046] In this embodiment, refer to Figure 3 , the heat dissipation space S2 is connected to the second cavity 210.

[0047] Through the above structure, the hot air in the accommodating chamber S1 can also be directly discharged to the outside through the heat dissipation space S2 to accelerate the heat dissipation in the accommodating chamber S1.

[0048] Of course, the present invention is not limited to the above-mentioned embodiments, and technicians familiar with the field may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications and substitutions are all included in the scope defined by the claims of this application.
