Abstract
Description
Technical Field
[0001] This invention relates to the field of industrial lighting technology, and in particular to a luminaire with an adjustable illumination angle. Background Technology
[0002] Traditional high-altitude lighting fixtures typically have cooling fans installed on the heat sink fins of the fixture housing to accelerate heat dissipation and improve cooling efficiency. However, during prolonged use in harsh outdoor environments, these cooling fans are susceptible to rain damage and malfunction. Furthermore, birds and other flying animals often nest on the heat sink fins, significantly impacting their cooling efficiency and reducing the fixture's lifespan.
[0003] Furthermore, a series of electronic components are housed inside the lamp housing. These components generate heat during operation, which needs to be dissipated promptly to prevent damage from high temperatures. Simply creating ventilation holes on the outside of the lamp housing allows rainwater to easily enter and damage the electronic components. Conversely, without ventilation holes, the accumulated heat inside the lamp housing cannot be effectively dissipated. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a lamp with an adjustable illumination angle, thereby solving the overall heat dissipation problem of the lamp from the inside out.

The cantilever has an air duct, which is a hollow cavity structure with one end open and the other end closed. The end face of the air duct has an air inlet and the side has an air outlet. The rotating shaft has a through hole along its central axis that connects with the air inlet. The air duct chamber has an air duct channel that connects with the air outlet.

An interference device is provided at the heat dissipation fins of the light-emitting body; the interference device includes an elastic element and a rocking hammer provided on the elastic element. The rocking hammer is affected by the airflow blown out from the opening of the diversion chamber, causing it to shake and strike the heat dissipation fins of the light-emitting body.
[0007] In one embodiment, the elastic element is a cylindrical spring, one end of which is fixed to the center of the heat dissipation fins of the light-emitting body, and the rocking hammer is fixed to the other end of the cylindrical spring.

[0018] Please refer to the following: Figures 1 to 4 This invention discloses a rotatable and adjustable illumination angle lamp 10, which includes: a central control box 100, a driving device 200 (such as...). Figure 6 As shown), rotating shaft 300 (as shown) Figure 6 (as shown), cantilever 400, light source 500, air guide chamber 600, blower 700 (as shown) Figure 3 (As shown). In this embodiment, the light-emitting element 500 is preferably an LED lamp.
[0019] Please refer to the following: Figures 1 to 4The rotating shaft 300 is rotatably mounted on the side wall of the central control box 100. The drive device 200 is housed in the central control box 100 and is drivenly connected to the rotating shaft 300. The cantilever 400 is mounted on the rotating shaft 300. The light source 500 and the air guide chamber 600 are mounted on the cantilever 400.
[0020] like Figure 5 As shown, the cantilever 400 has an air duct 410, which is a hollow cavity structure with one end open and the other end closed. An air inlet 411 is provided on the end face of the air duct 410, and an air outlet 412 is provided on the side. The rotating shaft 300 has a through hole 301 along its central axis that aligns with the air inlet 411 (e.g., ...). Figure 6 As shown), the air guide chamber 600 has an air guide channel 601 that connects to the air outlet 412 (as shown). Figure 3 (As shown).
[0021] like Figure 3 As shown, the blower 700 is installed inside the central control box 100. The blower 700 is used to blow outside air into the central control box 100. The airflow passes through the through hole 301, the air inlet 411, the air outlet 412, and the air guide channel 601 in sequence and flows back to the outside and blows towards the heat dissipation fins 501 of the light source 500.
[0022] like Figure 3 and Figure 4 As shown, specifically, the air guide chamber 600 has a main flow chamber 610 and several branch flow chambers 620 connected to the main flow chamber 610. The opening of the main flow chamber 610 is connected to the air outlet 412, and the opening of each branch flow chamber 620 is facing the heat dissipation fins 501 of each light source 500.
[0023] Among them, the mainstream warehouse 610 extends in a straight line from bottom to top, while the diversion warehouse 620 is set at an angle from top to bottom.
[0024] like Figure 5 As shown, furthermore, an interference device 800 is provided at the heat dissipation fins 501 of the light emitter 500; the interference device 800 includes an elastic element 810 and a rocking hammer 820 disposed on the elastic element 810. The rocking hammer 820 is affected by the airflow blown out from the opening of the diversion chamber 620, causing it to shake and strike the heat dissipation fins 501 of the light emitter 500. In this practical example, the elastic element 810 is a cylindrical spring, one end of which is fixed to the center position of the heat dissipation fins 501 of the light emitter 500, and the rocking hammer 820 is fixed to the other end of the cylindrical spring; the rocking hammer 820 is preferably a conical aluminum alloy structure.
[0025] The working principle of the rotatable and adjustable illumination angle lamp 10 described above will be explained below: like Figure 3As shown, when the blower 700 is working, it blows outside air into the central control box 100. The components inside the central control box 100 generate heat when they are working. The relatively cool outside air enters the central control box 100 and blows the heat inside the box out through the through hole 301 at the central axis of the rotating shaft 300. like Figure 3 As shown, the airflow blasted out from the through hole 301 then flows back to the outside through the air inlet 411, the air outlet 412, and the air guide channel 601. The airflow flowing back to the outside will also blow towards the heat dissipation fins 501 of the light source 500, thereby performing air-cooled heat dissipation treatment on the heat dissipation fins 501. It should be noted that the internal components of the enclosure include integrated circuit boards and motors, which generate less heat and have a lower temperature compared to the light source 500. Therefore, the airflow returning from the enclosure to the outside can be directly blown onto the heat dissipation fins 501 of the light source 500, achieving the purpose of air-cooled heat dissipation of the heat dissipation fins 501. As can be seen from the above, by installing a blower 700 inside the central control box 100, the airflow travels along a predetermined channel through the blowing action of the blower 700, which not only solves the problem of heat dissipation for the components inside the box (such as...) Figure 6 As shown in the figure, it also solves the problem of heat dissipation of heat dissipation fins 501 at the same time, and the structure is simple and effective. The traditional method is to install a cooling fan at the heat dissipation fins 501. The cooling fan can only dissipate heat from the heat dissipation fins 501 and cannot dissipate heat from the inside of the box. Moreover, the cooling fan is exposed to the outside and is easily damaged by rain and may malfunction. In this invention, the air guide chamber 600 has a main flow chamber 610 and several diversion chambers 620 connected to the main flow chamber 610. The main flow chamber 610 extends straight up from the bottom, and the diversion chambers 620 are inclined from the top down. This structural design makes it difficult for rainwater from the outside to enter the air guide channel 601, and even more difficult to enter the inside of the box, thus effectively protecting the components inside the box. Regarding the heat dissipation of lamps, there is another factor to consider, namely, as mentioned in the background technology: birds and other flying birds often nest at the heat dissipation fins, which seriously affects the heat dissipation efficiency of the heat dissipation fins; therefore, it is necessary to "humanely" drive away birds and other flying birds. To address this, the present invention includes an interference device 800 at the heat dissipation fins 501 of the light-emitting body 500. Specifically, the interference device 800 includes an elastic member 810 and a rocking hammer 820 mounted on the elastic member 810. The airflow blowing from the opening of the diversion chamber 620 acts on the rocking hammer 820. Simultaneously, under the turbulence effect of the protrusions of the heat dissipation fins 501, the rocking hammer 820 will shake and strike the heat dissipation fins 501 of the light-emitting body 500. Therefore, the interference device 800 and the airflow blowing from the opening of the diversion chamber 620 effectively cooperate. The interference device 800 does not require an additional power device. While the airflow performs wind-cooling heat dissipation on the heat dissipation fins 501, it also blows the rocking hammer 820, causing it to shake. It achieves knocking, thereby effectively driving away birds and other flying birds; it should be further emphasized that, because the heat dissipation fin 501 is equipped with an interference device 800, which protrudes from the heat dissipation fin 501, the entire heat dissipation fin 501 no longer has a relatively flat surface. Even if the rocking hammer 820 does not shake for a long time, birds and other flying birds will find it difficult to nest due to the influence of the rocking hammer 820, thus effectively solving the heat dissipation problem of the heat dissipation fin; furthermore, the interference device 800 occupies only a small position on the heat dissipation fin 501, so the heat dissipation fin 501 will not be blocked by the heat dissipation fin 501 and will not have a heat dissipation problem. The interference device 800 mainly drives away birds and other flying birds by shaking and knocking. In this embodiment, the drive device 200 includes a servo motor 210 (e.g., Figure 6 As shown in the figure, a rotating shaft 300 is rotatably mounted on the side wall of the central control box 100 via bearings. The servo motor 210 is connected to the rotating shaft 300 via the conveyor belt. The servo motor 210 drives the rotating shaft 300 to rotate via the conveyor belt, which in turn drives the cantilever frame 400 to rotate. As a result, the light source 500 and the air guide chamber 600 mounted on the cantilever frame 400 also rotate, thereby realizing the adjustment of the illumination angle of the light source 500. Since the air guide chamber 600 also rotates at the same time, the positional relationship between the air guide chamber 600 and the light source 500 remains unchanged. The air blown out by the air guide chamber 600 can directly reach the heat dissipation fins 501 without affecting the heat dissipation of the heat dissipation fins 501. In this invention, the rotatable and adjustable illumination angle lamp 10 also includes a mounting base 900 (e.g., Figure 2 As shown, the central control box 100 is rotatably mounted on the mounting base 900. The luminaire can be installed as a whole at the desired location via the mounting base 900.
[0026] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
