Description

Technical Field

[0001] The present application relates to the technical field of LED lamps, and more specifically, to a protective structure for an LED lamp. Background Art

[0002] As a new type of solid-state lighting source, LEDs offer numerous significant advantages. They boast high electro-optical conversion efficiency, converting a significant portion of electrical energy into light, making them more energy-efficient than traditional lighting sources. LEDs also offer a long lifespan, reaching tens of thousands of hours or even longer, significantly reducing the frequency and cost of lamp replacements. Their compact size and light weight make them easy to install and design, adapting to a variety of lighting scenarios. Furthermore, LEDs contain no hazardous substances, such as mercury, making them environmentally friendly.

[0003] In some industrial production workshops, the operation of large-scale machinery generates a large amount of heat, causing the surrounding temperature to rise. These large-scale machinery typically consumes a large amount of energy to operate, and their internal components, such as motors and transmissions, continuously generate frictional heat and electromagnetic heat during operation. Furthermore, certain machining processes, such as welding, cutting, and forging, also release a large amount of heat energy, causing the temperature in the workshop to rise rapidly. LED lamps operating in such high-temperature environments are susceptible to overheating. Excessive temperatures accelerate the aging of components such as LED chips and packaging materials, shortening their service life. Furthermore, high temperatures can cause malfunctions in the LED lamp's circuit boards. In high-temperature environments, overheating can damage the electronic components on the LED lamp's circuit boards, affecting the lamp's proper operation. Utility Model Content

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; it is obvious that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0030] Reference Figure 1-Figure 5 A protective structure for an LED lamp includes an LED lamp body 1, an installation cavity 5 is provided inside the LED lamp body 1, and a protective component is provided on the top of the installation cavity 5;

[0031] The protection component includes two temperature sensors 7, a connecting plate 10 is provided inside the mounting cavity 5, a controller 9 is provided at one end of the connecting plate 10, and a relay 11 is provided at the end of the connecting plate 10 away from the controller 9;

[0032] The heat dissipation assembly includes a heat sink 12, the number of which is set to be multiple, and the multiple heat sinks 12 are fixedly connected to the installation cavity 5. The tops of the multiple heat sinks 12 are provided with gathering plates 13, and the two gathering plates 13 on both sides are set at an angle.

[0033] Two temperature sensors 7 monitor the temperature of the first LED light strip 2 and the second LED light strip 3 in real time. When the first LED light strip 2 or the second LED light strip 3 generates heat during operation, the temperature sensors 7 convert the sensed temperature changes into electrical signals and transmit them to the controller 9. The controller 9 has a preset temperature threshold. Once the temperature of a light strip exceeds the threshold, the controller 9 will activate the corresponding control program.

[0034] For example, if the temperature of the first LED light strip 2 is too high, the controller 9 sends a command to the relay 11, which quickly switches the circuit, turning off the first LED light strip 2 and activating the second LED light strip 3. At this point, the first LED light strip 2 stops working and begins to dissipate heat with the help of the heat dissipation component. After the second LED light strip 3 has been working for a period of time and its temperature also exceeds the threshold, the controller 9 controls the relay 11 again to switch back to the first LED light strip 2, and the alternating use cycle continues.

[0035] By alternating the two light strips, overheating and damage caused by long-term continuous operation of a single light strip can be avoided, greatly extending the overall service life of the LED light. This is especially true in some occasions where long-term lighting is required, such as industrial production workshops. This alternating use method can ensure continuous and stable lighting and reduce the cost and trouble caused by frequent replacement of lamps.

[0036] Reference Figure 2-Figure 4A plurality of heat dissipation grooves 14 are provided on the top of the LED lamp body 1, and the plurality of heat dissipation grooves 14 are all located on the top of the gathering piece 13. A first LED light bar 2 and a second LED light bar 3 are provided inside the mounting cavity 5. Two temperature sensors 7 are respectively located on the top of the first LED light bar 2 and the second LED light bar 3. Two heat transfer plates 6 are provided on the top of the first LED light bar 2 and the second LED light bar 3, and the top of each heat transfer plate 6 is connected to the inner side of the mounting cavity 5.

[0037] During operation of the first and second LED light strips 2 and 3, heat is generated by conducting heat through the heat transfer plate 6 to the multiple heat sinks 12. This increases the contact area with the air, improving heat dissipation efficiency. Concentrating fins 13 on top of the heat sinks 12 collect and direct the heat to the top heat sinks 14. These heat sinks 14 provide a more efficient path for air circulation, allowing heat to dissipate more quickly into the surrounding environment, thereby reducing the temperature of the light strips.

[0038] By effectively dissipating heat and lowering the operating temperature of the first LED light bar 2 and the second LED light bar 3, the aging speed of the internal components can be slowed down, their service life can be extended, and problems such as damage to the first LED light bar 2 and the second LED light bar 3 and circuit failure caused by overheating can be reduced, thereby reducing maintenance and replacement costs.

[0039] Reference Figure 3-Figure 5 A magnetic frame 15 is provided on the inner side of each heat dissipation groove 14, a filter plate 16 is provided inside each heat dissipation groove 14, an iron sheet is provided at the bottom of each filter plate 16, and each magnetic frame 15 is magnetically connected to the iron sheet at the bottom of the corresponding filter plate 16. A through hole is opened inside the LED lamp body 1, and a heat dissipation fan 17 is provided inside the through hole.

[0040] The iron sheet at the bottom of the filter screen plate 16 is magnetically connected to the magnetic frame 15 inside the heat dissipation groove 14. This connection method makes the installation and removal of the filter screen plate 16 very convenient. When the filter screen plate 16 needs to be cleaned or replaced, it can be easily removed from the magnetic frame 15.

[0041] When the LED lamp body 1 is in operation, the heat generated by the first LED light bar 2 and the second LED light bar 3 is transferred to the plurality of heat sinks 12 through the heat transfer plate 6. The heat collecting fins 13 on the top of the heat sink 12 collect the heat and guide it to the heat dissipation grooves 14 on the top. The heat dissipation grooves 14 increase the air circulation channel, allowing the heat to be dissipated to the surrounding environment more quickly.

[0042] On the other hand, the filter plate 16 inside the heat dissipation groove 14 can prevent dust and other impurities from entering the lamp body without affecting the air circulation. When the heat dissipation fan 17 inside the through hole works, it accelerates the flow of air and further improves the heat dissipation efficiency.

[0043] The heat dissipation groove 14, the heat dissipation fin 12, the gathering fin 13 and the heat dissipation fan 17 jointly constitute a high-efficiency heat dissipation system. The heat dissipation groove 14 increases the air flow area, the heat dissipation fin 12 increases the contact area with air, the gathering fin 13 guides the heat to the heat dissipation groove 14, and the heat dissipation fan 17 accelerates the air flow. These factors work together to quickly and effectively dissipate the heat generated by the light bar, reduce the temperature of the light bar, improve the light-emitting efficiency and stability of the light bar, and prolong the service life of the light bar.

[0044] With reference to Figure 1-Figure 3 Both ends of the LED lamp body 1 are provided with cover plates 4, and one end of the first LED light bar 2 and the second LED light bar 3 is provided with an indicator light 8. The controller 9 is electrically connected with the temperature sensor 7, the indicator light 8, the relay 11 and the heat dissipation fan 17.

[0045] The temperature sensor 7 continuously monitors the temperature of the first LED light bar 2 and the second LED light bar 3 and transmits the temperature signal to the controller 9. If one of the light bars is overheated, the controller 9 will send a command to the relay 11 to switch the circuit, so that the light bar with normal temperature works, and the overheated light bar is turned off. In addition, the controller 9 can also control the working state of the heat dissipation fan 17 according to the temperature change. When the temperature rises, the heat dissipation fan 17 is started to accelerate heat dissipation. In this way, through the cooperation of the temperature sensor 7, the controller 9, the indicator light 8, the relay 11 and the heat dissipation fan 17, intelligent temperature monitoring, light bar switching and high-efficiency heat dissipation of the LED lamp are realized, and the stable operation and safety of the lamp under working conditions are ensured.

[0046] When the temperature of the first LED light bar 2 and the second LED light bar 3 is normal, the indicator light 8 displays a color (such as green); when the temperature of the light bar exceeds the preset threshold, the controller 9 determines which light bar is overheated according to the signal of the temperature sensor 7, and controls the corresponding indicator light 8 to display another color (such as red) to remind the user of the working state of the light bar.

[0047] Working principle: In actual use, when the LED lamp body 1 is installed in an industrial production workshop and the power is turned on, the first LED light bar 2 or the second LED light bar 3 starts to work to provide illumination for the environment. The two temperature sensors 7 will monitor the temperature of the first LED light bar 2 and the second LED light bar 3 in real time. When the first LED light bar 2 or the second LED light bar 3 generates heat during work, the temperature sensor 7 can sensitively sense the change of the surrounding temperature and convert the temperature change into an electric signal, which is then transmitted to the controller 9.

[0048] Controller 9 has pre-set temperature thresholds. Once the temperature of a particular light bar exceeds this threshold, controller 9 immediately activates the corresponding control program. For example, if the temperature of the first LED light bar 2 is too high, controller 9 sends a command to relay 11, which responds quickly, switching the circuit and shutting down the overheated first LED light bar 2 while activating the second LED light bar 3. At this point, the first LED light bar 2 stops operating and begins dissipating heat using the heat sink. After the second LED light bar 3 has operated for a period of time and its temperature also exceeds the threshold, controller 9 again controls relay 11 to switch back to the first LED light bar 2, and the alternating operation continues.

[0049] The heat generated during the operation of the first LED light strip 2 or the second LED light strip 3 will be conducted to the multiple heat sinks 12 through the heat transfer plate 6. Due to the large number of heat sinks 12, the contact area with the air is increased, thereby improving the heat dissipation efficiency. The gathering piece 13 on the top of the heat sink 12 gathers the heat and guides it to the heat dissipation groove 14 on the top. On the one hand, the heat dissipation groove 14 provides more channels for heat dissipation, promotes air circulation, and enables heat to be dissipated to the surrounding environment faster. When the temperature continues to rise, the controller 9 will control the heat dissipation fan 17 located in the internal through hole of the LED lamp body 1 to work. The heat dissipation fan 17 accelerates the flow of air and further improves the heat dissipation efficiency.

[0050] In addition, an indicator light 8 is provided at one end of the first LED light bar 2 and the second LED light bar 3. Under the action of the controller 9, the indicator light 8 will display different colors according to the temperature status of the first LED light bar 2 and the second LED light bar 3 to remind the user of the working status of the first LED light bar 2 and the second LED light bar 3. The cover plates 4 at both ends of the LED lamp body 1 serve to seal the LED lamp body 1, protect the internal components from external factors such as dust and moisture, and maintain a stable working environment.

[0051] The coordinated function of temperature sensor 7, controller 9, indicator light 8, relay 11, cooling fan 17, and heat dissipation components enables intelligent temperature monitoring of the LED lamp, light bar switching, and efficient heat dissipation, ensuring stable operation and safety of the lamp under various practical operating conditions. This design prevents overheating and damage to individual light bars caused by prolonged continuous operation, significantly extending the overall service life of the LED lamp and reducing the cost and inconvenience of frequent lamp replacement. It is particularly suitable for applications requiring long-term lighting.

[0052] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
