[0033] The following reference Figures 1 to 10 The various embodiments of the present invention will be described in detail. Those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0034] A garden landscape lighting device, such as Figure 1 , Figure 2 , Figure 4 As shown, the lamp includes a lamp post 1, a lamp cover 2 at the top of the lamp post 1, a circular lamp housing 3 inside the lamp cover 2, a top wall ring 4 fixedly connected to the top of the lamp housing 3, an energy-saving lamp ring 5 connected to the power supply at the bottom of the top wall ring 4, a light-transmitting cover 6 threadedly installed at the bottom of the lamp housing 3, a central circular hole in the middle of the top wall ring 4, an upwardly extending heat exhaust ring 7 fixedly connected to the inner wall of the central circular hole of the top wall ring 4, the heat exhaust ring 7 having a through structure from top to bottom, a heat-absorbing material sealing plate 8 fixedly connected to the bottom of the heat exhaust ring 7, a heat conduction device inside the heat conduction device, a cooling fan 9 at the top of the heat conduction device, a temperature sensor inside the heat exhaust ring 7, the temperature sensor and the cooling fan 9 being connected to the controller and the power supply respectively, and the cooling fan 9 being used to cool the energy-saving lamp ring 5;

[0035] When the temperature inside the lamp housing 3 and the light-transmitting cover 6 gradually rises, the temperature is conducted to the heat conduction device. The temperature sensor detects the high temperature and transmits the signal to the controller. The controller starts the cooling fan 9 to rotate. The cooling fan 9 can quickly exhaust the high temperature to the outside, realize the rapid cooling of the energy-saving lamp ring 5, and improve its service life.

[0036] When the temperature drops below the detection value of the temperature sensor, the temperature sensor sends a signal to the controller, and the controller turns off the cooling fan 9.

[0037] like Figure 4 , Figure 5 , Figure 8 As shown, the heat conduction device includes heat conduction sheets 10 made of heat-absorbing material. Multiple heat conduction sheets 10 located inside the exhaust ring 7 are fixedly connected to the top of the sealing plate 8. A partition 11 is fixedly connected between the tops of the multiple heat conduction sheets 10. A cooling fan 9 is fixedly installed on the top of the partition 11. An exhaust port 12 is provided on the top of the exhaust ring 7.

[0038] Temperature is conducted through the sealed plate 8 to multiple heat-conducting plates 10. During the rotation of the cooling fan 9, the heat on the heat-conducting plates 10 can be quickly dissipated, and the heat-conducting plates 10 can also quickly absorb heat, thus accelerating the heat dissipation speed of the energy-saving lamp ring 5.

[0039] like Figure 6 , Figure 8 As shown, the sealing plate 8 has multiple heat dissipation holes 13, and the upper edge of the heat dissipation ring 7 has multiple exhaust holes 14. The heat dissipated by the energy-saving lamp ring 5 can quickly enter the space between the partition plate 11 and the sealing plate 8 through the heat dissipation holes 13 and be absorbed by the heat-conducting plate 10, and then be discharged through the exhaust holes 14.

[0040] like Figure 4 , Figure 6 , Figure 9 As shown, a protective shell 15 is fixedly connected to the top of the top wall ring 4. The protective shell 15 is sleeved on the outside of the exhaust ring 7. A closing ring 16 is fixedly installed on the top of the protective shell 15. An internal round hole is opened in the middle of the closing ring 16. The internal round hole is sealed on the exhaust ring 7 and located below the exhaust port 14. Four sets of symmetrical heat dissipation holes 17 are evenly arranged on the top wall ring 4. The heat dissipation holes 17 are located between the protective shell 15 and the exhaust ring 7.

Each heat dissipation box 18 has a through structure. A triggering device is provided inside each heat dissipation box 18.

[0041] like Figure 4As shown, a positioning shaft 19 is coaxially fixedly connected to the bottom end of the cooling fan 9. The positioning shaft 19 passes through the sealing plate 8 and extends into the interior of the lamp housing 3. A synchronous shaft 20 is rotatably connected to the bottom end of the light-transmitting cover 6. An external scraper 21 is fixedly connected to the bottom end of the synchronous shaft 20. The external scraper 21 slides in contact with the outer surface of the light-transmitting cover 6. An internal scraper 22 is fixedly connected to the top end of the synchronous shaft 20. The internal scraper 22 slides in contact with the inner surface of the light-transmitting cover 6. A rectangular block is fixedly connected to the bottom end of the positioning shaft 19. A rectangular groove is opened at the top end of the synchronous shaft 20. The rectangular block can be detachably installed in the rectangular groove.

[0042] The cooling fan 9 rotates the synchronous shaft 20 via the positioning shaft 19. During the rotation of the outer scraper 21 and the inner scraper 22, the inner and outer surfaces of the light-transmitting cover 6 can be cleaned, improving the gloss and aesthetics.

[0043] like Figure 4 , Figure 10 As shown, the triggering device includes a trigger rod 23. A baffle plate 24 is slidably connected inside each heat sink 18. A compression rod 25 is fixedly connected to the inner end of the baffle plate 24. An internal hole 26 is provided on each compression rod 25. A baffle rod 27 located in the internal hole 26 is fixedly connected inside each heat sink 18. The baffle rod 27 can slide back and forth along the internal hole 26. A compression spring 28 located in the internal hole 26 is fixedly connected to each baffle rod 27. The other end of the compression spring 28 is fixedly connected to the inner wall of the internal hole 26. A triangular block 29 is fixedly connected to the other end of each compression rod 25. The inclined surface of the triangular block 29 is set downward. Multiple temperature devices are provided inside the protective shell 15. A trigger rod 23 is slidably arranged inside each temperature device.

[0044] like Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 As shown, an extension rod 30 is fixedly connected to the inner wall of each heat dissipation box 18. Each temperature device includes a heat absorption cylinder 31. A vertical heat absorption cylinder 31 is fixedly connected to each extension rod 30. The heat absorption cylinder 31 is located directly below the triangular block 29. The top and bottom ends of the heat absorption cylinder 31 are closed structures. An expansion liquid 32 is provided inside each heat absorption cylinder 31. A slider 33 located above the expansion liquid 32 is slidably connected inside each heat absorption cylinder 31. The edge of the slider 33 is slidably sealed to the heat absorption cylinder 31. A trigger rod 23 is coaxially fixedly connected to the top end of each slider 33. The upper end of the trigger rod 23 slides through the top end of the heat absorption cylinder 31 and is located below the triangular block 29. A groove 34 is opened on the inclined surface of each triangular block 29. The top end of the trigger rod 23 is slidably connected to the inner wall of the groove 34.

[0045] A heat-absorbing frame 35 is fixedly connected between multiple extension rods 30. A spiral heat dissipation strip 36 is fixedly installed on the outer wall of the heat dissipation ring 7. The heat dissipation strip 36 has the characteristic of rapid heat absorption. A rectangular hole 37 is opened on the outside of each heat dissipation box 18. Multiple ventilation holes 38 are provided on the outside of the lamp body shell 3. The ventilation holes 38 have the function of heat absorption and ventilation.

[0046] As the temperature inside the light-transmitting cover 6 continues to rise, the high-temperature gas enters between the protective shell 15 and the exhaust ring 7 through the heat dissipation hole 17. As the temperature continues to rise, the corresponding heat-absorbing cylinder 31 transfers heat to the expanding liquid 32. The expanding liquid 32 gradually expands and pushes the slider 33 to slide upward. The trigger rod 23 pushes the slide groove 34 upward. The triangular block 29 pushes the extrusion rod 25 and the baffle plate 24 to move outward. The extrusion spring 28 is compressed.

[0047] When the baffle plate 24 moves to the outer top of the heat sink 18, the baffle plate 24 stops moving and opens the rectangular hole 37. The high-temperature gas between the protective shell 15 and the heat exhaust ring 7 is quickly discharged through the rectangular hole 37, which accelerates the cooling speed and improves the cooling efficiency.

[0048] like Figure 2 , Figure 3 ,picture, Figure 5 , Figure 6 As shown, the top of the exhaust ring 7 is fixedly connected to multiple support rods 39, and the top of the multiple support rods 39 is fixedly connected to a top plate 40. The top of the lampshade 2 is fixedly connected to a sealing block 41. The top plate 40 is evenly provided with four bottom guide grooves 42, and the sealing block 41 is evenly provided with four top guide grooves 43. Each top guide groove 43 is correspondingly provided with the bottom guide groove 42 below it. The top of the sealing block 41 is rotatably connected to a threaded rod 44, and an adjusting block 45 is threadedly connected to the threaded rod 44. Each top guide groove 43 is slidably connected to an L-shaped clamping rod 46. The top of each clamping rod 46 is rotatably connected to a linkage rod 47, and the other end of the linkage rod 47 is rotatably connected to the adjusting block 45.

[0049] When installation is required, insert the lower end of each clamping rod 46 into the corresponding four bottom guide slots 42, rotate the threaded rod 44 to move the adjusting block 45 upward, and each linkage rod 47 moves the corresponding clamping rod 46 closer to the threaded rod 44 until the bottom ends of the four clamping rods 46 are locked against the top plate 40, thus realizing the quick installation of the lamp and facilitating quick replacement.

[0050] like Figure 1 , Figure 2As shown, the top of the closed block 41 is threaded with a protective cover 48, which can protect the threaded rod 44. Multiple reinforcing rods 49 are fixedly connected between the lamp post 1 and the lamp cover 2, which improves the stability of the lamp cover 2. The bottom of the lamp post 1 is fixedly connected with a fixing plate 50, which facilitates the installation of the lamp post 1.
