Description

Technical Field

[0001] This invention relates to the field of energy-saving lighting equipment technology, and in particular to an energy-saving indoor stadium light that facilitates heat dissipation. Background Technology

[0002] LED stadium lights are high-powered lighting fixtures commonly used in stadiums. Stadium lights are typically installed in elevated positions, thus providing a large illumination area to meet the lighting needs of large venues. However, LED stadium lights generate considerable heat over time; excessively high temperatures accelerate the aging of the electrical components inside the LED lights, reducing their lifespan.

[0003] For example, Chinese patent CN113217860B discloses a high-efficiency heat dissipation integrated LED stadium light, including a mounting bracket, a mounting shell mounted on the top of the mounting bracket, an LED light strip mounted on the bottom of the mounting shell, a fan mounted on the right inner wall of the mounting shell, a heat insulation cover mounted on the top of the mounting shell, and a heat absorption device mounted on the mounting shell below the heat insulation cover. The heat absorption device extends into the interior of the mounting shell and includes: a liquid storage shell, legs, a diversion pipe, heat absorption balls, and through slots. The liquid storage shell is connected to the top of the mounting shell through the legs, the diversion pipe is mounted at the bottom of the liquid storage shell and is rotatably connected to the liquid storage shell through bearings, and the diversion pipe extends into the mounting shell. Multiple heat absorption balls are mounted on the diversion pipe inside the mounting shell, and multiple through slots are opened on the heat absorption balls. A rotating mechanism for driving the heat absorption device is mounted on the mounting shell. However, this technical solution has a complex structure and is not convenient for maintenance.

[0024] Please refer to Figures 1 to 7An energy-saving indoor stadium light 100 with convenient heat dissipation according to one embodiment of the invention includes a support assembly 10, a lighting assembly 20, and a heat dissipation assembly 30. The support assembly 10 includes a lamp housing 11, a lampshade 12, and a bracket 13. The lampshade 12 covers the lamp housing 11 and has a through hole 121 and a guide cavity 122 communicating with the through hole 121. One end of the bracket 13 is rotatably connected to the lampshade 12, and the other end is used to fix a support. The lighting assembly 20 is installed inside the lamp housing 11. The heat dissipation assembly 30 includes a first heat sink 31, a sliding plate 32, a second heat sink 33, a guide post 34, an elastic element 35, and a blower 36. The first heat sink 31 is spaced apart on the side of the lampshade 12 away from the lamp housing 11. The sliding plate 32 slides on the first heat sink 31 and is used to cover the guide cavity. 122; One end of the second heat sink 33 is mounted on the slide plate 32, and the other end slides on the first heat sink 31. There are multiple first heat sinks 31 and multiple second heat sinks 33, and they correspond one-to-one; There are multiple guide posts 34 and multiple elastic members 35, and they correspond one-to-one. One end of the guide post 34 is mounted on the lampshade 12, and the other end passes through the slide plate 32. The elastic member 35 is sleeved on the guide post 34. One end of the elastic member 35 abuts against the slide plate 32, and the other end abuts against the guide post 34; The blower 36 is mounted on the lampshade 12, and the blower 36 is connected to the through hole 121; When it is necessary to speed up heat dissipation, as the blower 36 continuously blows air into the through hole 121, the high-pressure airflow passes through the guide cavity 122 and pushes open the slide plate 32, so that the second heat sink 33 slides on the first heat sink 31. In this embodiment, the energy-saving indoor stadium light 100, which facilitates heat dissipation, uses high-pressure airflow to push open the sliding plate 32, allowing the second heat sink 33 to slide onto the first heat sink 31, thereby increasing the heat dissipation area. At the same time, the high-pressure airflow carries some heat away from the guide cavity 122, accelerating heat dissipation.

[0025] like Figures 1 to 5As shown, in this embodiment, the support assembly 10 includes a lamp housing 11, a lamp shade 12, and a bracket 13. The lamp shade 12 covers the lamp housing 11. Optionally, the lamp shade 12 and the lamp housing 11 are fixed by multiple screws. The lamp shade 12 has a through hole 121 and a guide cavity 122 communicating with the through hole 121. The air blown out by the blower 36 flows sequentially through the through hole 121 and the guide cavity 122. One end of the bracket 13 is rotatably connected to the lamp shade 12, and the other end is used to fix it to a support to adjust the angle of the lamp shade 12. Optionally, the through hole 121 is funnel-shaped, and the diameter of the through hole 121 decreases from the end communicating with the blower 36 to the end communicating with the guide cavity 122, so that the air blown out by the blower 36 is injected into the guide cavity 122 under high pressure. Further, the flow guiding cavity 122 includes a first cavity 1221 and a second cavity 1222. One end of the first cavity 1221 is connected to the through hole 121, and the other end is connected to the second cavity 1222. The end of the second cavity 1222 away from the first cavity 1221 is disposed corresponding to the slide plate 32. In one embodiment, both the first cavity 1221 and the second cavity 1222 are funnel-shaped. The diameter of the first cavity 1221 decreases from the end near the lamp housing 11 to the end near the second cavity 1222 to concentrate airflow. The diameter of the second cavity 1222 decreases from the end near the first cavity 1221 to the end near the slide plate 32 to further concentrate airflow and make the airflow high-pressure to push open the slide plate 32.

[0026] like Figure 3 and Figure 5 As shown, the support assembly 10 also includes multiple guide strips 14, each of which protrudes from the inner wall of the lampshade 12 and is spirally arranged along the inner wall of the lampshade 12; optionally, the guide strips 14 extend spirally from the first cavity 1221 to the second cavity 1222, thereby guiding the airflow toward the second cavity 1222.

[0027] like Figure 1 and Figure 2As shown, the support assembly 10 further includes a fixing seat 15, a pin 16, and a fastener 17. There are two fixing seats 15, two fasteners 17, and two pins 16, each corresponding to one other. The two fixing seats 15 are respectively installed at both ends of the lampshade 12, and both ends of the bracket 13 are rotatably connected to the corresponding fixing seats 15. The pin 16 is inserted into the bracket 13 and the fixing seat 15, and the bracket 13 rotates around the pin 16. The fastener 17 is used to fix the bracket 13 and the fixing seat 15. The bracket 13 has multiple limiting grooves 131, and the fastener 17 is selectively inserted into one of the limiting grooves 131 to adjust the angle. Optionally, the fastener 17 is threadedly connected to the fixing seat 15. Further, the support assembly 10 also includes a support block (not shown) installed inside the lamp housing 11. Figure 4 As shown, the support assembly 10 also includes a sealing ring 18, which is used to seal the lamp housing 11 and the lamp shade 12 to improve airtightness.

[0028] like Figure 1 and Figure 3 As shown, the lighting component 20 is installed inside the lamp housing 11; optionally, the lighting component 20 includes a control board 21 and an LED lamp 22 electrically connected to the control board 21, and the control board 21 is installed on a support block.

[0029] like Figure 1 , Figures 3 to 7 As shown, the heat dissipation assembly 30 includes a first heat sink 31, a sliding plate 32, a second heat sink 33, a guide post 34, an elastic element 35, and a blower 36. The first heat sink 31 is spaced apart on the side of the lampshade 12 away from the lamp housing 11. The sliding plate 32 is slidably disposed on the first heat sink 31 and is used to cover the airflow cavity 122. One end of the second heat sink 33 is mounted on the sliding plate 32, and the other end is slidably disposed on the first heat sink 31. There are multiple first heat sinks 31 and multiple second heat sinks 33, and they correspond one-to-one. There are multiple guide posts 34 and multiple elastic elements 35, each corresponding to the other. One end of each guide post 34 is mounted on the lampshade 12, and the other end passes through the slide plate 32. Each elastic element 35 is sleeved on the guide post 34, with one end abutting against the slide plate 32 and the other end abutting against the guide post 34. The blower 36 is mounted on the lampshade 12 and connects to the through hole 121. Optionally, the cross-section of the guide post 34 is T-shaped. Further, the elastic element 35 is a spring, and the blower 36 is an air pump, which is existing technology. When faster heat dissipation is needed, as the blower 36 continuously blows air into the through hole 121, the high-pressure airflow passes through the guide cavity 122 and pushes open the slide plate 32, causing the second heat sink 33 to slide onto the first heat sink 31, thereby increasing the heat dissipation area.

[0030] In one embodiment, each of the first heat sinks 31 has an exhaust hole 311 at one end near the lampshade 12. Under the action of airflow, the slide plate 32 slides on the first heat sink 31. When the slide plate 32 slides above the exhaust hole 311, part of the airflow is discharged through the exhaust hole 311, thereby carrying away the heat on the first heat sink 31 and accelerating heat dissipation. Optionally, each of the first heat sinks 31 also has a heat dissipation hole 312. The heat dissipation hole 312 is located on the side of the exhaust hole 311 away from the lampshade 12. Under the action of airflow, the slide plate 32 slides on the first heat sink 31. When the slide plate 32 slides above the heat dissipation hole 312, part of the airflow is discharged through the exhaust hole 311 and the heat dissipation hole 312, further carrying away the heat on the first heat sink 31 and accelerating heat dissipation. In one embodiment, each of the first heat sinks 31 is spaced apart to form a vertical heat dissipation groove 313, and the first heat sink 31 is provided with a horizontal heat dissipation groove for heat dissipation; the second heat sink 33 has a similar structure to the first heat sink 31, and the second heat sink 33 is provided with a receiving groove 331 to receive the first heat sink 31.

[0031] like Figure 5 and Figure 7 As shown, the slide plate 32 includes a base plate portion 321 and a positioning portion 322. The positioning portion 322 is disposed along the periphery of the base plate portion 321, and the second heat sink 33 is mounted on the base plate portion 321. The lampshade 12 is provided with a slot 123 to accommodate the positioning portion 322. Optionally, the slide plate 32 further includes a reinforcing portion 323 mounted on the base plate portion 321. The reinforcing portion 323 is disposed corresponding to the flow guide cavity 122 to ensure structural sturdiness.

[0032] In one embodiment, the lamp housing 11, lamp shade 12, bracket 13, air guide strip 14, fixing base 15, support block, first heat sink 31, slide plate 32 and second heat sink 33 are all made of metal.

[0033] This energy-saving indoor stadium light 100, which facilitates heat dissipation, also includes a controller (not shown), a temperature sensor (not shown), and a timer (not shown). The controller, temperature sensor, and timer are all electrically connected to the control board 21. The temperature sensor is used to test the temperature of the control board 21, and the timer is used to calculate the operating time of the blower 36. Optionally, the temperature sensor is existing technology. The controller controls the operation of the LED light 22 and the blower 36. The blower 36 includes different speed settings, each corresponding to a different rotation speed and a different response temperature. The response temperature includes a first-level response temperature, a second-level response temperature, and a third-level response temperature.

[0034] In use, when the temperature sensor detects that the temperature of the control board 21 has reached the first-level response temperature, the controller activates the blower 36, and the airflow enters the guide cavity 122 through the through hole 121. As the blower 36 continuously delivers gas into the guide cavity 122, the high-pressure airflow lifts the slide plate 32, thereby compressing the elastic element 35. Consequently, both the slide plate 32 and the second heat sink 33 slide along the first heat sink 31, increasing the heat dissipation area. Moreover, the high-pressure airflow is discharged through the gap between the slide plate 32 and the lampshade 12, simultaneously carrying away some of the heat generated by the lighting component 20 from the guide cavity 122, accelerating heat dissipation. The blower 36 continuously inputs airflow into the guide cavity 122, and the airflow blows towards the lighting component 20, accelerating heat dissipation. Within a preset time, when the temperature of the control board 21 drops to a safe temperature, the blower 36 stops operating. Under the rebound of the elastic element 35, the slide plate 32 abuts against the lampshade 12, and the slide plate 32 covers the guide cavity 122.

[0035] like Figure 6 and Figure 7 As shown, during the cooling process at the first-level response temperature, if the temperature of the control board 21 has not dropped to a safe temperature after the blower 36 has been operating continuously for a preset time, the blower 36 increases its rotation speed. Alternatively, if the temperature of the control board 21 rises from the first-level response temperature to the second-level response temperature within the preset time, the blower 36 increases its rotation speed, and the high-pressure airflow further lifts the slide plate 32, causing the slide plate 32 to slide above the exhaust port 311. The second heat sink 33 further slides along the first heat sink 31, further expanding the heat dissipation area, and some airflow is discharged through the exhaust port 311, accelerating the heat dissipation of the first heat sink 31. By increasing the airflow speed, the gas flow in the guide cavity 122 is accelerated, and the heat in the guide cavity 122 is discharged more quickly. If the temperature of the control board 21 drops to the first-level response temperature within the preset time, the blower 36 decelerates; or, if the temperature of the control board 21 drops to a safe temperature, the blower 36 stops operating.

[0036] Similarly, during the cooling process at the secondary response temperature, if the temperature of the control board 21 has not dropped to a safe temperature after the blower 36 has been operating continuously for a preset time, the blower 36 will increase its rotation speed. Alternatively, if the temperature of the control board 21 rises from the secondary response temperature to the tertiary response temperature within the preset time, the blower 36 will increase its rotation speed, and the high-pressure airflow will further lift the slide plate 32, causing it to slide above the heat dissipation hole 312. The second heat sink 33 will then slide further along the first heat sink 31, further expanding the heat dissipation area. Part of the airflow will be discharged through the heat dissipation hole 312 and the exhaust hole 311, accelerating the heat dissipation of the first heat sink 31. If the temperature of the control board 21 drops to the secondary or primary response temperature within the preset time, the blower 36 will decelerate to the corresponding speed; or, if the temperature of the control board 21 drops to a safe temperature, the blower 36 will stop operating.

[0037] The energy-saving indoor stadium light 100 of the present invention facilitates heat dissipation by using high-pressure airflow to push open the sliding plate 32, so that the second heat sink 33 slides onto the first heat sink 31, thereby increasing the heat dissipation area; at the same time, the high-pressure airflow carries some heat away from the guide cavity 122, thereby accelerating heat dissipation.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] 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.
