The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0018] The first embodiment of the present application is:

[0019] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall structure of the outer tube structure of the downlight of the first embodiment of the utility model. Figure 2 It is a structural schematic diagram of the second heat dissipation fin 109 of the first embodiment of the utility model.

[0020] The outer tube structure of the downlight of the utility model includes a base 101, a lamp body 102, a tube shell 103, a heat-conducting contact sheet 104, a heat-conducting pipe 105, a first heat-dissipating fin 106, a top cover 107, a fan 108, a second heat-dissipating fin 109, and a heat-insulating gasket 110. It solves the problem that although the prior art can achieve heat dissipation, the fan blades will drive the bristles to clean the fan heat holes while rotating, thereby causing noise, and the structure is complex and the manufacturing cost is high. It is understandable that the above solution can also be used to improve the heat dissipation efficiency.

[0021] In this embodiment, the base 101 is in a circular ring shape, and the lamp body 102 is a prior art, which is fixedly mounted on the base 101. The heat dissipation assembly is mounted on the base 101 to dissipate heat for the lamp body 102, thereby solving the problem that although the prior art can achieve heat dissipation, the fan blades will drive the bristles to clean the fan heat holes while rotating, thereby causing noise, and the structure is complex and the manufacturing cost is high.

[0022] The cylindrical shell 103 is fixedly connected to the base 101 and is sleeved on the outside of the lamp body 102. The thermal contact sheet 104 is installed on the lamp body 102 and is located on the outside of the lamp body 102. The thermal pipe 105 extends into the cylindrical shell 103 and is fixedly connected to the thermal contact sheet 104. The first heat dissipation fin 106 is fixedly connected to the thermal pipe 105 and is located at one end of the thermal pipe 105 away from the thermal contact sheet 104. The top cover 107 is fixedly connected to the cylindrical shell 103 and is located at the cylindrical shell 103 away from the base. The lamp body 102 is provided on one side of the lamp body 101. The cylindrical shell 103 is a circular tube body, which is installed on the top of the base 101 and is covered on the outside of the lamp body 102. Ventilation holes are evenly opened on the circumference of the cylindrical shell 103 to facilitate air flow. The thermal contact sheet 104 is made of copper and is annular in shape. It is arranged around the outer circumference of the lamp body 102 and is in close contact with the outer wall of the lamp body 102, so that the heat of the lamp body 102 can be transferred to the thermal contact sheet 104. The thermal pipe 105 is a copper pipe, and there are multiple of them. The cylindrical shell 103 is provided with a circle of through holes. The thermal pipe 105 is provided with a circle of through holes. The number of the heat conducting pipes 105 corresponds to the number of the through holes, the heat conducting pipes 105 penetrate the through holes and extend into the cylindrical shell 103, one end of the heat conducting pipes 105 extending into the cylindrical shell 103 is connected to the heat conducting contact sheet 104, so that the heat on the heat conducting contact sheet 104 can be transferred to the heat conducting pipes 105, the first heat dissipating fins 106 are installed on one end of the heat conducting pipes 105 located outside the cylindrical shell 103, and the heat can be quickly dissipated under the action of the first heat dissipating fins 106, and the top cover 107 is fixedly installed on the top of the cylindrical shell 103 A connecting plug is provided on the top cover 107, and the connecting plug is connected to the lamp body 102 through a wire. After the connecting plug is connected to a power source, the lamp body 102 can be operated. By providing a heat conductor on the outside of the lamp body 102, the heat of the lamp body 102 can be extracted, so that the heat can be quickly dissipated, thereby achieving heat dissipation of the lamp body 102, which solves the problem that although the prior art can achieve heat dissipation, the fan blades will drive the bristles to clean the fan heat holes while rotating, thereby causing noise, and the structure is complex and the manufacturing cost is high.

[0023] Secondly, the fan 108 is fixedly connected to the top cover 107 and is located on a side of the top cover 107 close to the lamp body 102. A mounting through hole is provided on the top cover 107. The fan 108 is installed on the top cover 107 through the mounting through slot. The blowing surface of the fan 108 faces the lamp body 102. The air blowing of the fan 108 improves the heat dissipation efficiency.

[0024] At the same time, the second heat dissipation fins 109 are installed on the lamp body 102 and are located on the side of the lamp body 102 close to the fan 108. The second heat dissipation fins 109 can help heat to be quickly transferred out from the heat source of the lamp body 102. Through the cooperation of the fan 108 and the second heat dissipation fins 109, the heat dissipation efficiency is further improved.

[0025] In addition, the thermal insulation gasket 110 is fixedly installed on the cylinder shell 103, and the heat-conducting pipe 105 is installed on the cylinder shell 103 through the thermal insulation gasket 110. The thermal insulation gasket 110 is made of thermal insulation material, and the number of the thermal insulation gaskets 110 corresponds to the number of the heat-conducting pipes 105. The thermal insulation gasket 110 plays a role of heat insulation, thereby avoiding damage to the cylinder shell 103 due to excessive heat generation during heat transfer.

[0026] In this embodiment, a plurality of groups of the heat pipes 105 and the first heat dissipation fins 106 are arranged on the peripheral side of the lamp body 102, so that the heat of the lamp body 102 is quickly conducted away from the heat source and quickly dissipated into the surrounding environment. In addition, with the cooperation of the second heat dissipation fins 109 and the fan 108, the heat dissipation is further accelerated, thereby achieving rapid heat dissipation of the lamp body 102, which solves the problem that although the prior art can achieve heat dissipation, the fan blades will drive the bristles to clean the fan heat holes while rotating, thereby causing noise, and the structure is complex and the manufacturing cost is high.

[0027] The second embodiment of the present application is:

[0028] See also Figure 3 , Figure 3 It is a schematic diagram of the overall structure of the outer tube structure of the downlight of the second embodiment of the utility model. On the basis of the first embodiment, the outer tube structure of the downlight of this embodiment further includes a fixed ear seat 201 and a spring cantilever 202 .

[0029] In this embodiment, the outer tube structure of the downlight further includes a fixing ear seat 201 and a spring cantilever 202, and the installation of the lamp tube is facilitated by the above-mentioned solution.

[0030] Among them, the fixed ear seat 201 is fixedly connected to the tube shell 103 and is located on the outer wall of the tube shell 103; the spring cantilever 202 is fixedly installed on the fixed ear seat 201, and the number of the fixed ear seats 201 is two, which are symmetrically arranged on the outer peripheral side of the tube shell 103, and the number of the spring cantilever 202 corresponds to it. The fixed ear seat 201 is provided with a shaft rod, and the spring cantilever 202 is installed on the fixed ear seat 201 through the shaft rod. When in use, the two spring cantilevers 202 are simultaneously pulled upward, and then the lamp tube is placed as a whole in the installation hole of the ceiling. Thereafter, the lamp tube is released, and the spring cantilever 202 is reset under the action of elastic force, so that the base 101 and the spring cantilever 202 clamp the ceiling, thereby fixing the lamp tube, and the spring cantilever 202 is used to facilitate the installation of the lamp tube.
