A high-efficiency heat-dissipation reflecting bowl comprises a reflecting body 1 and a heat dissipation body 2 for cooling the reflecting body 1; the heating body 2 includes a heat radiation chamber 3 and a heat radiator 4 for cooling the heat radiation chamber 3; the reflector 1 is curved, the inner side surface is used for accommodating a light source, and the heat dissipation chamber 3 is arranged on the outer side surface of the reflector 1; a truncated cone-shaped heat transfer body 5 is arranged in the heat dissipation chamber 3, one end surface of the heat transfer body 5 is connected with the inner side wall of the heat dissipation chamber 3, and the other end surface of the heat transfer body 5 is connected with the outer side wall of the reflector 1.

The reflector is arranged on the lamp and used for condensing light, so that light loss can be reduced. In mounting, the reflector comprises a light source. In the utility model, the reflector 1 is in a curved surface shape and is used for reflecting light of a light source, aiming at enabling the reflected light to be emitted out of the reflector 1 in a balanced manner, and the lamp body achieves higher brightness and range. On the other hand, in the light source illumination process, the filament releases a large amount of heat and transfers the heat to the reflector 1, so that the temperature of the reflector 1 is increased, the reflection effect of the reflector 1 is influenced, and the service life of the light source is also influenced. Therefore, the utility model is also provided with a heat radiation body 2 and a reflecting body 1 which are integrally installed. The front end of the reflector 1 is provided with a light source for irradiation, and the rear end is provided with a radiator 2 for cooling the reflector 1. Specifically, the radiator 2 comprises a radiator 4 with a main cooling function, a radiating chamber 3 is arranged between the radiator 4 and the radiator 2 at an interval, the radiating chamber 3 is hollow inside, internal ventilation and heat dissipation are facilitated, and the radiator 4 is convenient to transmit cold air to the reflector 1 through the radiating chamber 3 for cooling. The heat radiation chamber 3 is further provided with a circular truncated cone-shaped heat conductor 5, and the heat radiation chamber 3 has a housing and contains the heat conductor 5. The heat transfer body 5 is made of high heat conduction material (such as metal), the upper end surface and the lower end surface are respectively connected with the light reflecting body 1 and the radiator 4, the heat in the light reflecting body 1 is efficiently transferred to the heat transfer body 5 and the radiator 4 by utilizing the heat transfer principle, the heat dissipation area is increased, and the heat dissipation efficiency is accelerated. Therefore, the reflector 1 can be efficiently cooled whether the radiator 4 adopts the air-cooled cooling heat transfer body 5 to increase the wind receiving area or adopts the heating cooling heat transfer body 5 to efficiently transfer heat.

It should be noted that the heat transfer body 5 may be cylindrical, but under the condition of the same bottom surface area, the side surface area of the cylindrical heat transfer body 5 is smaller than that of the truncated cone-shaped heat transfer body 5, so the wind receiving area is relatively small, and the heat radiation effect is relatively weak. In some embodiments, the heat transfer body 5 is also made of a material with a high specific heat capacity (e.g., the specific heat capacity of aluminum is higher in metal); by utilizing the heat absorption characteristic of the heat transfer body 5, the heat transfer body 5 can absorb more heat, and the temperature rising speed of the heat transfer body 5 and the light reflecting body 1 is slow, so that the service life of the light reflecting bowl can be better prolonged.

Further, a plurality of heat transfer bodies 5 are provided, and a plurality of heat transfer bodies 5 are arranged at intervals. In order to facilitate the heat transfer bodies 5 to receive air over the entire surface, the heat transfer bodies 5 are provided at intervals, and cold air flows through the gaps between the heat transfer bodies 5. The cold air increases the velocity of flow in narrow gap, improves the rate that cold air carried the heat.

The shell of the heat dissipation chamber 3 is provided with a plurality of through holes 31, the inside of the heat dissipation chamber 3 is communicated with the outside, and outside air can enter the heat dissipation chamber 3. That is, the heat transfer body 5 is in an open environment, and the heat in the heat transfer body 5 can be dissipated everywhere. The heat sink 4 blows out air carrying heat of the heat transfer body 5 to be dissipated in the external environment.

In one embodiment, the reflector 1 comprises a housing 11 and a plate body 12, the housing 11 is connected with the heat dissipation chamber 3, and the plate body 12 is used for reflecting light.

The casing 11 covers the back surface of the reflector 1, and the casing 11 is connected to the heat dissipation chamber 3 and the heat transfer body 5.

In one embodiment, the edge of the reflector 1 is provided with an outwardly extending hook ring 6 for easy capture. The hook ring 6 is arranged at the edge of the opening of the reflector 1. Since the surfaces of the plate body and the shell are smooth, the hook ring 6 facilitates the capture of the shell 11 or the plate body 12 when the shell 11 and the plate body 12 are assembled, so that the assembly is more convenient. On the other hand, it can be observed whether the housing 11 or the housing 12 is misaligned or protruded from the hook ring 6.
