Description

Technical Field

[0001] This invention relates to the field of light shows, and specifically to a temperature control and heat dissipation linkage device for light show lamps. Background Technology

[0002] Currently, the lighting fixtures for light shows on the market generally consist of a housing and a lampshade that are detachably connected by multiple bolts. A circuit board is located between the housing and the lampshade, and the circuit board contains wires connected to an external power source and multiple LEDs. The aforementioned lighting fixtures for light shows lack an effective heat dissipation structure and cannot adjust their heat dissipation according to the internal temperature of the fixture, which greatly reduces the lifespan of the fixtures. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a temperature control and heat dissipation linkage device for light show lamps that can perform intelligent heat dissipation.

[0004] Therefore, the present invention is implemented using the following technical solution:

[0005] A temperature control and heat dissipation linkage device for light show lamps includes a housing and a lampshade that are detachably connected by multiple bolts. A circuit board is provided between the housing and the lampshade. The circuit board has wires connected to an external power source and multiple LED beads. The device is characterized in that each LED bead has a heat dissipation cover with several heat dissipation holes. A heat conduction pipe is connected to the upper end of the heat dissipation cover. The other end of the heat conduction pipe extends towards the center point of the circuit board, and the inlet of the heat conduction pipe faces upward. The housing has an internal heat dissipation structure, which includes a wireless temperature sensor that can be aligned with the inlet of the heat conduction pipe.

[0006] Furthermore, the housing has a vertical chamber facing the heat pipe inlet, and the heat dissipation structure includes a bracket disposed in the vertical chamber. A first motor and a second motor are disposed on the bracket. The shaft of the first motor is connected to an extension shaft. The wireless temperature sensor is disposed at the lower end of the extension shaft. A fan wheel that is linked to the second motor is movably disposed on the extension shaft.

[0007] Furthermore, a long bearing is fitted onto the extended shaft, the wind turbine is fitted onto the outer sleeve of the long bearing, a first gear is fitted onto the upper part of the long bearing, and a second gear that meshes with the first gear is provided on the rotating shaft of the second motor.

[0008] Furthermore, the lower end of the extension shaft is provided with a support rod extending to each of the heat pipe inlets, the wireless temperature sensor is mounted on one of the support rods, and the other support rods are provided with a disc that can block the heat pipe inlets.

[0009] Furthermore, the bracket is equipped with a circuit board connected to wires, and the circuit board is equipped with a microcontroller and a receiver connected to each other. The receiver is used to receive signals from the wireless temperature sensor. The first motor and the second motor are connected to the microcontroller through wires, and the microcontroller controls the first motor and the second motor according to a set program.

[0010] Furthermore, the housing is provided with several ventilation holes aligned with the heat sink.

[0011] With the above technical solution, each LED bead is equipped with an individual heat sink and heat pipe. The wireless temperature sensor can detect the temperature at the inlet of the heat pipe. When the temperature is too high, the heat dissipation structure can dissipate heat from the heat pipe, heat sink and LED bead, and expel the hot air from the heat dissipation hole, effectively preventing the LED bead from being damaged due to overheating, and greatly improving the service life of the light show lighting fixtures.

[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0020] Referring to the above figures, the temperature control and heat dissipation linkage device for light show lamps provided by the present invention includes a housing 1 and a lampshade 2 detachably connected by multiple bolts 20. A circuit board 3 is provided between the housing 1 and the lampshade 2. The circuit board 3 is provided with wires connected to an external power supply and multiple LED beads. The device is characterized in that: each LED bead is provided with a heat dissipation cover 4, the heat dissipation cover 4 is provided with several heat dissipation holes 5, and a heat conduction pipe 6 is connected to the upper end of the heat dissipation cover 4. The other end of the heat conduction pipe 6 extends towards the center point of the circuit board 3, and the inlet of the heat conduction pipe 6 faces upward. The housing 1 is provided with an internal heat dissipation structure, which includes a wireless temperature sensor 7 that can be aligned with the inlet of the heat conduction pipe 6. The housing 1 has a vertical chamber 8 facing the inlet of the heat conduction pipe 6. The heat dissipation structure includes a bracket 9 disposed in the vertical chamber 8. A first motor 10 and a second motor 11 are disposed on the bracket 9. The shaft of the first motor 10 is connected to an extension shaft 12. The wireless temperature sensor 7 is disposed at the lower end of the extension shaft 12. The extension shaft 12 is movably connected to the first motor 10. The fan wheel 13 is linked by two motors 11. A long bearing 14 is sleeved on the extension shaft 12. The fan wheel 13 is sleeved on the outer sleeve of the long bearing 14. A first gear 15 is sleeved on the upper part of the long bearing 14. A second gear 16 that meshes with the first gear 15 is provided on the shaft of the second motor 11. A support rod 17 extending to the inlet of each of the heat pipes 6 is provided at the lower end of the extension shaft 12. The wireless temperature sensor 7 is provided on one of the support rods 17. The other support rods 17 are provided with a disc 18 that can block the inlet of the heat pipe 6. A circuit board connected to wires is provided on the bracket 9. A microcontroller and a receiver are connected to each other on the circuit board. The receiver is used to receive the signal from the wireless temperature sensor 7. The microcontroller compares the temperature value pre-input with the temperature received by the receiver. The first motor 10 and the second motor 11 are connected to the microcontroller through wires. The microcontroller controls the first motor 10 and the second motor 11 according to the set program. A number of vent holes 19 aligned with the heat sink 4 are provided on the housing 1.

[0021] The working principle of this invention is as follows: After the lamp is powered on, the microcontroller controls the first motor 10 to start, driving the extension shaft 12, support rod 17, disc 18 and wireless temperature sensor 7 to rotate slowly. This allows the wireless temperature sensor 7 to pass through each heat pipe 6 port for a certain period of time, so as to more accurately detect the temperature generated by each lamp bead. The long bearing 14 ensures that the extension shaft 12 does not drive the fan wheel 13 to rotate when it rotates. When the temperature detected by the wireless temperature sensor 7 exceeds the preset temperature value, the first motor 10 is stopped and the second motor is controlled. When 11 is activated, the wireless temperature sensor 7 is located at the inlet of the overheated heat pipe 6, while most of the other inlets of the heat pipe 6 are blocked by the disc 18. The second motor 11 drives the second gear 16 to rotate, which in turn drives the first gear 15, the long bearing 14, and the fan wheel 13 to rotate and provide targeted cooling to the overheated heat pipe 6, the heat sink 4, and the LED beads. The hot air is blown out of the heat sink 4 through the heat dissipation hole 5 and forms convection with the outside through the vent hole 19, so that the temperature control and heat dissipation are linked to provide intelligent heat dissipation for the lights used in the light show.

[0022] Reference Figure 3 , 4 As shown, the LED beads are arranged in a polygonal or ring-shaped pattern, referring to... Figure 5 As shown, the LEDs are distributed in a branched pattern. Regardless of whether the LEDs are distributed regularly or irregularly, the heat pipes 6 inlets of all LEDs are arranged in a ring, which better cooperates with the heat dissipation mechanism.

[0023] In this embodiment, each LED bead is equipped with an individual heat sink 4 and heat pipe 6. The wireless temperature sensor 7 can detect the temperature at the inlet of the heat pipe 6. When the temperature is too high, the heat dissipation structure can dissipate heat from the heat pipe 6, heat sink 4 and LED bead, and exhaust the hot air out of the heat dissipation hole 5, effectively preventing the LED bead from being damaged due to excessive temperature and greatly improving the service life of the light show lighting fixtures.

[0024] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
