Description

Technical Field

[0001] This utility model relates to the field of RGBW RGB contour lights, and more particularly to an RGBW RGB contour light with an auxiliary heat dissipation structure. Background Technology

[0002] RGBW contour lights are lighting devices with multiple color adjustment functions, often used for indoor and outdoor decoration, architectural contour lighting, and other occasions.

[0003] When RGBW contour lights are installed on buildings for lighting purposes, the internal LED beads do not completely convert electrical energy into light energy during the light-emitting process. A considerable portion of the energy is dissipated as heat. When the LED beads work continuously for a long time, the temperature inside the RGBW contour light frame and lampshade will continue to rise, causing the surface temperature of the LED beads to also rise. High temperatures will accelerate the aging of the internal materials of the LED beads and shorten their lifespan. Utility Model Content

[0004] The technical problem this invention aims to solve is that when RGBW contour lights are installed on buildings for lighting purposes, the internal LED beads do not completely convert electrical energy into light energy during the light-emitting process. A considerable portion of the energy is dissipated as heat. When the LED beads work continuously for a long time, the temperature inside the RGBW contour light frame and lampshade will continuously rise, causing the surface temperature of the LED beads to also rise. High temperatures will accelerate the aging of the internal materials of the LED beads and shorten their lifespan.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an RGBW contour light with an auxiliary heat dissipation structure, including an RGBW contour light frame, a lampshade is provided on one side of the RGBW contour light frame, a number of LED beads are provided on the inner wall of the lampshade on one side of the RGBW contour light frame, and a heat dissipation device is provided on one side of the RGBW contour light frame. The heat dissipation device can draw air into the air box through an air pump, and then cool it through a semiconductor cooling chip. Finally, the air is blown into the lampshade through a nozzle frame, and after heat exchange with the hot air inside, it is discharged from the heat dissipation holes to achieve the effect of cooling.

[0006] The effects achieved by the aforementioned components are as follows: The core of the RGBW contour light's operation lies in the collaborative work of the integrated RGBW four-color LED beads and the intelligent control chip. The LED beads contain red, green, and blue primary color LEDs and a white LED. The control chip receives pulse width modulation signals from an external controller and precisely adjusts the luminous intensity of the red, green, and blue LEDs, thus mixing millions of colors. Simultaneously, the white LED can work alone or in conjunction with the three primary colors to supplement color temperature, enhance brightness, or achieve a purer white light effect. Furthermore, the controller's preset dynamic program changes the color combination and brightness parameters of each LED bead in a time sequence. Through the internal circuitry of the lamp body, the entire row of LED beads changes synchronously or asynchronously according to preset logic, ultimately presenting a smooth, colorful, and dynamically changing RGB lighting effect on the object's outline. This satisfies both basic single-color constant illumination requirements and complex dynamic color transitions and pattern displays. During the use of the RGBW contour light, a heat dissipation device can be activated to cool its internal walls, reducing the temperature inside the RGBW contour light frame and lampshade, and preventing the LEDs from overheating. To prevent overheating and aging damage to LED chips, this method aims to extend the lifespan of LED chips.

[0007] Preferably, the heat dissipation device includes a mounting bracket and two nozzle brackets. A rectangular hole is symmetrically opened on one side of the RGBW contour light bracket, with both ends of the mounting bracket inserted into the inner wall of the rectangular hole. Several heat dissipation holes are symmetrically opened on both ends of the mounting bracket. A wind box is provided, with one side of the wind box fixedly mounted on one side of the mounting bracket. An air pump is provided, with its output end penetrating and mounted on one side of the wind box. A thermoelectric cooler is provided, with one side of the thermoelectric cooler fixedly mounted on one side of the wind box. Two guide tubes are provided, with one end of each guide tube penetrating and mounted on one side of the wind box, and the other two ends penetrating through both ends of the mounting bracket and then penetrating and mounted on the outer surface of the nozzle bracket. A limiting mechanism is provided between the mounting bracket and one side of the RGBW contour light bracket to limit and fix the mounting bracket inserted into the rectangular hole.

[0008] The effect achieved by the above components is as follows: By setting up a heat dissipation device, when the RGBW contour light is in use, the semiconductor cooling chip can be connected to the power supply first to cool the inner wall of the air box. Then, the air pump is started to draw air into the air box, allowing it to exchange heat with the inner wall of the air box to reduce its temperature. The air then enters the nozzle frame through the guide pipe and is blown into the RGBW contour light frame and lampshade, where it exchanges heat with the hot air inside the lampshade. The hot air is then discharged autonomously from the heat dissipation holes, thus cooling the LED beads during use, preventing overheating and aging damage to the LED beads, and improving the lifespan of the LED beads.

[0009] Preferably, the limiting mechanism includes several limiting rods, wherein one end of the limiting rod is rotatably mounted on one side of the RGBW contour lamp holder, and one side abuts against one side of the mounting bracket; and several torsion springs, wherein the inner wall of the torsion spring is sleeved on the outer surface of one end of the limiting rod, and both ends are respectively fixedly mounted on one side of the RGBW contour lamp holder and one side of the limiting rod.

[0010] The effect achieved by the above components is as follows: by setting a limiting mechanism, before inserting the mounting bracket into the rectangular hole, the limiting rod is manually rotated to a certain angle, causing the torsion spring to deform. After the mounting bracket is inserted into the rectangular hole, the limiting rod is released, so that under the reset action of the torsion spring, one end can abut against one side of the mounting bracket, limiting and fixing it, thus making it less likely for the mounting bracket to shake and slip out in the rectangular hole, improving the stability during use.

[0011] Preferably, an anti-slip block is fixedly installed on one side of the limiting rod, and the anti-slip block is made of rubber.

[0012] The effect achieved by the above components is that by setting anti-slip blocks, the contact friction on one side of the limit rod can be increased, making it more secure when it abuts against the mounting bracket.

[0013] Preferably, the longitudinal sections of the mounting bracket are trapezoidal, and the dimension of the end of the mounting bracket furthest from the bellows is smaller than the dimension of the other end.

[0014] The effect achieved by the above components is that by setting both ends of the mounting bracket to a trapezoidal shape, the area at both ends can be reduced, making it easier to quickly align with the rectangular hole and insert it, thus facilitating installation.

[0015] Preferably, both ends of the nozzle frame are fixedly mounted with round hole frames, wherein one side of the round hole frame is fixedly mounted on one side of the mounting frame.

[0016] The effect achieved by the above components is that by setting the round hole bracket, the two ends of the nozzle bracket can be limited and supported, making it less prone to shaking during use.

[0017] Preferably, a plurality of guide plates are fixedly installed on the inner wall of the wind box, wherein the plurality of guide plates are fixedly installed in a symmetrical and staggered manner on the inner wall of the wind box.

[0018] The effect achieved by the above components is that by setting up the baffle, the airflow path inside the air box can be extended, allowing it to fully exchange heat with the inner wall of the air box and improving the cooling efficiency.

[0019] Preferably, a plurality of elastic rubber blocks are fixedly installed on the inner wall of the heat dissipation hole, and the plurality of elastic rubber blocks are arranged at equal distances.

[0020] The effect achieved by the above components is as follows: by setting up elastic rubber blocks, the inner wall of the heat dissipation holes can be blocked and protected, so that external dust and impurities are not easy to enter the interior of the lampshade and RGBW outline lamp holder during use. If cold air is injected into the lampshade, the internal pressure will increase, which will cause the exchanged hot air to be discharged from the heat dissipation holes, causing the elastic rubber blocks to deform and open the heat dissipation holes for heat dissipation.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting up a heat dissipation device, when using the RGBW contour light, the semiconductor cooling chip can be connected to the power supply first to cool the inner wall of the air box. Then, the air pump is started to draw air into the air box, allowing it to exchange heat with the inner wall of the air box to reduce its temperature. The air then enters the nozzle frame through the guide pipe and is blown into the RGBW contour light frame and lampshade, where it exchanges heat with the hot air inside the lampshade. The hot air is then discharged autonomously from the heat dissipation holes. This process cools and dissipates heat from the LED beads during use, preventing overheating and aging damage to the LED beads and improving their lifespan. Attached Figure Description

[0032] The implementation of this utility model will be described in detail below with reference to specific embodiments.

[0033] In this embodiment:

[0034] Reference Figures 1-6 The diagram shows a preferred embodiment of the present invention.

[0035] Figures 1-6The RGBW contour light with an auxiliary heat dissipation structure shown includes an RGBW contour light frame 1, a lampshade 3 on one side of the RGBW contour light frame 1, and several LED beads 4 on the inner wall of the lampshade 3 on one side of the RGBW contour light frame 1. A heat dissipation device 2 is provided on one side of the RGBW contour light frame 1. The heat dissipation device 2 can draw air into the air box 24 through an air pump 25, and then cool it through a semiconductor cooling chip 26. Finally, the air is blown into the lampshade 3 through a nozzle frame 28, where it exchanges heat with the hot air inside and is discharged from the heat dissipation hole 23 to achieve the effect of cooling. The core of the RGBW contour light's operation lies in the collaborative work of the integrated RGBW four-color LED beads 4 and the intelligent control chip. Each bead contains red, green, and blue primary color LEDs and a white LED. The control chip receives pulse width modulation signals from an external controller and precisely adjusts the luminous intensity of the red, green, and blue LEDs, thus mixing millions of colors. Simultaneously, the white LED can work alone or in conjunction with the three primary colors to supplement color temperature, enhance brightness, or achieve a purer white light effect. Furthermore, the controller's preset dynamic program changes the color combination and brightness parameters of each LED bead sequentially over time. Through the internal circuitry of the light body, the entire row of LED beads changes synchronously or asynchronously according to preset logic, ultimately presenting a smooth, colorful, and dynamically changing contour lighting effect on the object's outline. This satisfies basic single-color constant illumination requirements while also enabling complex dynamic color transitions and pattern displays. During use, the heat dissipation device 2 can be activated to cool the internal walls of the RGBW contour light frame 1 and the lampshade 3, reducing the temperature inside and preventing damage to the LEDs. LED bead 4 is prone to overheating and aging damage, so this method can improve the lifespan of LED bead 4.

[0036] Figures 1-6The heat dissipation device 2 shown includes a mounting bracket 22 and two nozzle brackets 28. A rectangular hole 21 is symmetrically opened on one side of the RGBW contour light holder 1. Both ends of the mounting bracket 22 are inserted into the inner wall of the rectangular hole 21. Several heat dissipation holes 23 are symmetrically opened on both ends of the mounting bracket 22. A fan box 24 is fixedly mounted on one side of the mounting bracket 22. An air pump 25 is installed through one end of the air pump 25 on one side of the fan box 24. A semiconductor cooling chip 26 (model TEC1-12706) is fixedly mounted on one side of the fan box 24. Two guide tubes 27 are installed through one end of the guide tube 27 on one side of the fan box 24, and the other two ends are installed through both ends of the mounting bracket 22 and then through the outer surface of the nozzle bracket 28. A limiting mechanism 29 is located between the mounting bracket 22 and one side of the RGBW contour light holder 1 to limit and fix the mounting bracket 22 inserted into the rectangular hole 21. By setting up the heat dissipation device 2, when using the RGBW contour light, the semiconductor cooling chip 26 can be powered on first to cool the inner wall of the air box 24. Then, the air pump 25 is started to draw air into the air box 24, allowing it to exchange heat with the inner wall of the air box 24 to reduce its temperature. The air then enters the nozzle frame 28 through the guide pipe 27 and is blown into the interior of the RGBW contour light frame 1 and the lampshade 3, where it exchanges heat with the hot air inside the lampshade 3. The hot air is then discharged autonomously from the heat dissipation hole 23, thus cooling the LED beads during use and preventing overheating and aging damage to the LED beads 4, thereby improving the lifespan of the LED beads 4. It should be noted that the semiconductor cooling chip 26 is a mature technology and device in the existing field, and its internal structure, connection method, and principle will not be described further.

[0037] Figures 1-6The limiting mechanism 29 shown includes several limiting rods 291, one end of which is rotatably mounted on one side of the RGBW contour light holder 1, and one side abuts against one side of the mounting bracket 22; and several torsion springs 292, the inner wall of which is sleeved on the outer surface of one end of the limiting rod 291, and both ends are fixedly mounted on one side of the RGBW contour light holder 1 and one side of the limiting rod 291, respectively. By setting the limiting mechanism 29, before inserting the mounting bracket 22 into the rectangular hole 21, the limiting rod 291 is manually rotated to a certain angle, causing the torsion spring 292 to deform. After the mounting bracket 22 is inserted into the rectangular hole 21, the limiting rod 291 is released, so that under the reset action of the torsion spring 292, one end abuts against one side of the mounting bracket 22, limiting and fixing it, thus making it less likely for the mounting bracket 22 to shake and slip out in the rectangular hole 21, improving stability during use. A rubber anti-slip block 293 is fixedly installed on one side of the limiting rod 291. By setting the anti-slip block 293, the contact friction on one side of the limiting rod 291 can be increased, making it more secure when it abuts against the mounting bracket 22.

[0038] Figures 1-6 The mounting bracket 22 shown has trapezoidal longitudinal sections at both ends, with the end of the mounting bracket 22 furthest from the bellows 24 having a smaller dimension than the other end. By making both ends of the mounting bracket 22 trapezoidal, the area at both ends can be reduced, facilitating quick alignment and insertion into the rectangular hole 21, thus simplifying installation. Circular hole brackets 210 are fixedly mounted on the outer surfaces of both ends of the nozzle bracket 28, with one side of the circular hole bracket 210 fixedly mounted on one side of the mounting bracket 22. By providing the circular hole brackets 210, the ends of the nozzle bracket 28 can be limited and supported, preventing it from shaking during use.

[0039] Figures 1-6 The inner wall of the bellows 24 shown is fixedly equipped with several guide plates 211, which are symmetrically and alternately fixed in the inner wall of the bellows 24. By setting the guide plates 211, the airflow path inside the bellows 24 can be extended, allowing it to fully exchange heat with the inner wall of the bellows 24 and improving the cooling efficiency. The inner wall of the heat dissipation hole 23 is fixedly equipped with several elastic rubber blocks 212, which are arranged at equal intervals. By setting the elastic rubber blocks 212, the inner wall of the heat dissipation hole 23 can be blocked and protected, so that external dust and impurities are not easily allowed to enter the interior of the lampshade 3 and the RGBW contour lamp holder 1 during use. If cold air is injected into the lampshade 3, the internal pressure increases, causing the exchanged hot air to be discharged from the heat dissipation hole 23, causing the elastic rubber blocks 212 to deform and open the heat dissipation hole 23 for heat dissipation.

[0040] Working Principle: The core of the RGBW contour light's operation lies in the collaborative work of the integrated RGBW four-color LED beads and the intelligent control chip. The beads contain red, green, and blue primary color LEDs, as well as a white LED. The control chip receives pulse width modulation signals from an external controller and precisely adjusts the luminous intensity of the red, green, and blue LEDs, thus mixing millions of colors. Simultaneously, the white LED... It can work alone or in combination with three primary colors to supplement color temperature, enhance brightness, or achieve a purer white light effect. In addition, the controller's preset dynamic program will change the color combination and brightness parameters of each LED in time sequence. Then, through the series or parallel circuit structure inside the lamp body, the entire row of LEDs will change synchronously or asynchronously according to the preset logic. Finally, it will present a smooth, colorful and dynamic iridescent light effect on the outline of the object. It can not only meet the basic single-color constant light requirement, but also realize complex dynamic color transitions and pattern display. Before inserting the mounting bracket 22 into the rectangular hole 21, first manually rotate the limiting rod 291 to a certain angle to drive the torsion spring 292 to deform. Then, after inserting the mounting bracket 22 into the rectangular hole 21, release the limiting rod 291 so that under the reset action of the torsion spring 292, one end can abut against one side of the mounting bracket 22 to limit and fix it. When using the RGBW contour light, the semiconductor cooling chip 26 can be powered on first to cool the inner wall of the air box 24. Then, the air pump 25 is started to draw air into the air box 24, allowing it to exchange heat with the inner wall of the air box 24 to reduce its temperature. The air then enters the nozzle frame 28 through the guide pipe 27 and is blown into the RGBW contour light frame 1 and the lampshade 3, where it exchanges heat with the hot air inside the lampshade 3. The hot air is then discharged autonomously from the heat dissipation hole 23, thus cooling the LED beads during use, preventing overheating and aging damage to the LED beads 4, and improving the lifespan of the LED beads 4.

[0041] It should be noted that the RGBW contour lamp holder 1 can be positioned with an opening at the hot end of the semiconductor cooling chip 26 to facilitate heat dissipation.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
