[0019] Figure 1 This is an exploded view of the LED long-arm spotlight in the embodiment of this utility model. Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings. It should be noted that this embodiment is based on the present technical solution and provides detailed implementation methods and specific operation processes, but the protection scope of the present invention is not limited to this embodiment.

[0021] This embodiment provides an LED long-arm spotlight, such as... Figure 1 As shown, it includes a long-arm lamp holder 1, an LED light source module, a heat dissipation module, and a driver module;

[0022] The heat dissipation module includes a hollow heat pipe 3. The light source module is located at one end outside the heat pipe 3, and the driving module is located inside the heat pipe 3. The LED light source module and the driving module are electrically connected. The long arm lamp holder 1 includes a connecting long arm 11 and a lamp holder 12. One end of the connecting long arm 11 is connected to the lamp holder 12, and the other end is detachably connected to the surface of the heat pipe 3 through a universal joint 13.

[0023] It should be noted that in the LED long-arm spotlight of this embodiment, the heat generated by the LED light source module can be quickly conducted to the heat dissipation pipe and dissipated through the surface of the heat dissipation pipe.

[0024] In this embodiment, the LED light source module includes a lampshade 21 and an LED light board 22. A light board mounting shell 31 is provided at one end of the heat dissipation pipe 3. The LED light board 22 is disposed inside the light board mounting shell 31, and the lampshade 21 is snapped onto the front end of the light board mounting shell 31. The light source emitted from the LED light board 22 is diffused outwards through the lampshade, and the heat generated by the LED light board 22 is transferred to the heat dissipation pipe 3 through the light board mounting shell 31. When maintenance or replacement of the LED light board 22 is required, the lampshade 21 can be removed to expose the LED light board 22.

[0025] In this embodiment, the heat pipe 3 is made of aluminum alloy and has an anodized film on its surface, which provides good heat dissipation and corrosion resistance.

[0026] On the one hand, aluminum alloys are easy to process and can be made into various complex shapes to meet different needs. On the other hand, aluminum alloys have a high thermal conductivity* (approximately 200–250 W / m·K), second only to copper (approximately 400 W / m·K), but far higher than other common metals (such as iron, which has only 80 W / m·K). Therefore, the heat pipe has excellent thermal conductivity. In addition, aluminum alloys have a suitable heat volume, which can temporarily store heat and then release it evenly, avoiding local overheating. Moreover, aluminum alloys have a low density, which can effectively reduce the weight of the lamp. When an LED is working, approximately 70–80% of the electrical energy is converted into heat energy. If the heat cannot be dissipated quickly, it will cause the LED chip to overheat, light decay, or even damage. In this embodiment, the heat generated by the LED light board can be quickly conducted to the heat pipe, preventing the LED chip from overheating.

[0027] In this embodiment, the universal head 13 is connected to the connecting plate 14. The shape of the connecting plate 14 matches the shape of the outer surface of the heat dissipation pipe 3 and is detachably attached to the outer surface of the heat dissipation pipe 3.

[0028] In this embodiment, the driving module includes an LED constant current driving power supply 4. The LED constant current driving power supply 4 can provide a stable current to the LED light source module, ensuring the stability of light output.

[0029] Furthermore, in this embodiment, the driving module also includes a DIP switch 5, which is electrically connected to the LED constant current driving power supply 4 and is used to control the on / off state of the power supply.

[0030] Furthermore, in this embodiment, the other end of the heat pipe 3 also includes a rear cover structure, which includes a rear cover 6 and a baffle 7. The other end of the heat pipe 3 is open, and the rear cover 6 covers the other end of the heat pipe 3. The rear cover 6 has a through hole in the middle for the front end of the DIP switch 5 to pass through. The front end of the DIP switch 5 passes through the through hole and is electrically connected to the LED constant current driving power supply. The baffle 7 covers the rear end of the DIP switch 5 and is engaged with the rear cover 6. The baffle 7 has a hole in the middle, and the switch button at the rear end of the DIP switch 5 is exposed through the hole.

[0031] Furthermore, in this embodiment, the front end of the rear cover 6 is provided with a snap-fit ​​protrusion 61, and the other end of the heat dissipation pipe 3 is provided with a matching snap-fit ​​groove 32, with the snap-fit ​​protrusion 61 snapping into the snap-fit ​​groove 32. In this embodiment, the rear cover 6 is further connected to the other end of the heat dissipation pipe 3 by screws 8. When it is necessary to replace or maintain components such as the power supply and DIP switches, the rear cover and the cover can be removed from the heat dissipation pipe first.

[0032] In practical applications, the LED light source module can employ high-efficiency LED chips and COB packaging technology to improve luminous efficiency and reliability. It can also combine LED chips with various color temperatures, allowing the LED light source module to switch between multiple color temperatures (such as white light, yellow light, warm white light, etc.). Furthermore, optical components such as lenses and reflectors can be used to adjust the beam angle and achieve uniform beam distribution. Additionally, the LED long-arm spotlight of this embodiment also considers aesthetic appeal.

[0033] For those skilled in the art, various corresponding changes and modifications can be made based on the above technical solutions and concepts, and all such changes and modifications should be included within the protection scope of the claims of this utility model.
