Description

Technical Field

[0001] This invention relates to the field of lighting technology, and in particular to an explosion-proof LED lighting system and its driving power module. Background Technology

[0002] In flammable and explosive industrial environments, such as petroleum, chemical, and mining fields, lighting fixtures not only need to meet basic lighting functions but also have extremely high requirements for safety, reliability, and long lifespan. While LED lighting fixtures offer advantages such as high luminous efficacy and energy saving...

[0003] Chinese patent CN120212449A discloses an LED explosion-proof lamp, comprising: an explosion-proof lamp housing, wherein a light source cavity is provided inside the explosion-proof lamp housing, and a light source board is provided inside the light source cavity; and several heat dissipation fins are fixedly connected to the top of the explosion-proof lamp housing in a ring array; a power supply housing, wherein a power supply cavity and a wiring cavity are provided inside the power supply housing; and a dust concentration detection mechanism, wherein the dust concentration detection mechanism is used to detect the dust concentration in the air.

[0004] However, these lights generate a lot of heat during operation. If the heat cannot be dissipated in time, it will lead to accelerated chip light decay, a significantly shortened lifespan, and may even become an explosion source due to high temperatures. Existing heat dissipation solutions for explosion-proof LED lights mostly rely on static heat sinks or simple air duct designs. During long-term operation, dust, oil, and other impurities easily accumulate on the heat dissipation surface, severely hindering heat conduction and convection, resulting in a sharp decline in heat dissipation efficiency and making it difficult to ensure long-term stable operation under harsh conditions. In addition, the aforementioned industrial scenarios often require focused or scanning lighting of specific areas, which requires the lights to have the ability to adjust the lighting angle and range. However, traditional adjustment mechanisms usually rely on rigid transmission components such as mechanical linkages or electric push rods, which have complex structures, have play, and are prone to mechanical wear and sparks.

[0022] The heat dissipation unit 3 includes a mounting plate 106. A heat dissipation ring plate 304 is located on the top of the mounting plate 106. The heat dissipation ring plate 304 absorbs the heat generated by the LED light panel 107 through the mounting plate 106. A linear drive device 302 is located in the middle of the heat dissipation ring plate 304. A rotating ring 309 is located at the bottom of the linear drive device 302, and the rotating ring 309 is rotatably mounted on the top of the mounting plate 106. The linear drive device 302 can be a miniature push rod, an electric drive rod 310, or a magnetic mechanism, etc. A sliding sleeve 303 is located at the output end of the linear drive device 302. A gas pipe 306 is located on the outer surface of the sliding sleeve 303. A solenoid valve 307 is located on the outer side of the gas pipe 306. The gas pipe 306 and the sliding sleeve 303 interact with each other. The sliding connection allows the linear drive device 302 to drive the sliding sleeve 303 to slide longitudinally along the inside of the gas pipe 306. The inner diameter of the gas pipe 306 is provided with a limiting rod 301. The bottom end of the limiting rod 301 passes through the heat dissipation ring plate 304 and is fixedly connected to the surface of the mounting plate 106. The inner diameter of the sliding sleeve 303 is slidably connected to the surface of the limiting rod 301. The top end of the limiting rod 301 is connected to the top of the inner wall of the lamp housing 101.

The rotary drive mechanism 305 can be a micro motor 102 or a rotary motor, etc., and can drive the limiting rod 301 to rotate inside the lamp housing 101.

[0023] The bottom of the sliding sleeve 303 is provided with an air intake channel 308, and the bottom of the sliding sleeve 303 near the interior of the air intake channel 308 is provided with a solenoid valve 2. The solenoid valve 2 is used to control the flow or sealing of the air intake channel 308. Multiple drive rods 310 are extended from the outer surface of the sliding sleeve 303. The bottom of each drive rod 310 is provided with multiple linearly arranged flexible rods 311. The interior of the flexible rods 311 is set with a hollow structure, and the interior of the flexible rods 311 is connected to the interior of the air intake channel 308 through the drive rods 310. A return spring is provided below the sliding sleeve 303, and the end of the return spring away from the sliding sleeve 303 is fixedly connected to the top of the mounting plate 106. The return spring is located inside the gas pipe 306.

[0024] When the linear drive device 302 is in the extended state, the sliding sleeve 303 moves along the outer surface of the limiting rod 301 toward its top, the gas pipe 306 is in a negative pressure state, the solenoid valve 1 307 is in the open state, the gas pipe 306 can be drawn into the gas pipe 306 through the solenoid valve 1 307, the gas pipe 306 gradually becomes in a positive pressure state, and the solenoid valve 2 is in the closed state.

[0025] When the linear drive device 302 is in the retracted state, the sliding sleeve 303 moves along the outer surface of the limiting rod 301 toward its bottom end, the inside of the gas pipe 306 is in a high-pressure state, the first solenoid valve 307 is in the closed state, and the second solenoid valve is in the open state. The gas in the gas pipe 306 can enter the interior of the flexible rod 311 through the air inlet channel 308 in the sliding sleeve 303, and the flexible rod 311 is in an expanded state.

[0026] The top of the lamp housing 101 is provided with a mounting mechanism 2. The mounting mechanism 2 includes a multi-directional square tube 201. Multiple slide rods 202 are slidably provided inside the multi-directional square tube 201. A mounting pad 203 is provided at the end of the slide rod 202 away from the multi-directional square tube 201. Multiple threaded structures 204 are provided inside the mounting pad 203. The multiple slide rods 202, the mounting pad 203 and the threaded structures 204 are used to install and fix the lamp housing 101 through the multi-directional square tube 201.

[0027] The present invention also provides a driving power module, which is used to adjust the lighting direction of the aforementioned explosion-proof LED lighting system. The driving power module is located inside the lighting mechanism 1 and includes at least two flexible air bags 108. The two flexible air bags 108 are located on the left and right sides of the inner wall of the lamp housing 101. The outer surfaces of the two flexible air bags 108 are in close contact with one side of the movable plate 105. Each of the two flexible air bags 108 is provided with a micro air pump, and the two micro air pumps can draw external gas into the flexible air bags 108, so that the flexible air bags 108 are in an inflated state. The two flexible air bags 108 can cooperate with the movable plate 105 and the hinge to adjust the illumination direction and range of the LED lamp panel 107.

[0028] First, during installation, the lamp housing 101 is fixed in the desired position using the multi-directional square tube 201, slide bar 202, and mounting pad 203 of the mounting mechanism 2. The slide bar 202 can slide within the multi-directional square tube 201 to accommodate different installation angles, and the threaded structure 204 inside the mounting pad 203 ensures a secure and reliable installation.

[0029] In use, the direction and range of illumination can be adjusted simply by using the LED lamp panel 107 in conjunction with the movable plate 105, the flexible air bag 108 in the drive power module, and the micro air pump (not shown in the figure). Specifically, when the illumination angle needs to be adjusted, the micro air pumps on the left and right sides are controlled to draw external gas into the corresponding flexible air bag 108, causing it to expand. After the flexible air bag 108 expands, it pushes the movable plate 105. The movable plate 105, through a hinge (not shown in the figure), causes the LED lamp panel 107 to deflect slightly left and right on the inner wall of the lamp housing 101, thereby changing the direction of light illumination. At the same time, the micro motor 102 drives the transmission gear ring 103 to rotate through the transmission wheel 104, causing the lower shell of the lamp housing 101 to rotate, further expanding the flexibility of the illumination range adjustment. Secondly, during heat dissipation, the heat generated by the LED lamp panel 107 inside the lamp housing 101 can be discharged to the outside through the heat dissipation ring plate 304. The heat dissipation ring plate 304 contacts the LED light panel 107 through the mounting plate 106, absorbs the heat generated by the LED, and dissipates the heat to the surrounding environment through its own heat dissipation structure.

[0030] However, while the heat dissipation ring plate 304 can indeed absorb the heat generated by the LED panel 107 and dissipate it to the outside, its surface will gradually accumulate dust during use or develop stains when exposed to humid environments, thus affecting heat dissipation efficiency. At this point, the linear drive device 302 drives the sliding sleeve 303 to move longitudinally along the limit rod 301, and in conjunction with the control of the gas pipe 306 and the solenoid valve, the following cleaning and heat dissipation enhancement mechanism is achieved. The sliding sleeve 303 moves to the top along the limiting rod 301, creating a negative pressure inside the gas pipe 306. Solenoid valve 1 307 opens, and external gas is drawn into the gas pipe 306. At this time, solenoid valve 2 closes, and the flexible rod 311 remains in a gas-free state.

[0031] The sliding sleeve 303 moves towards the bottom along the limiting rod 301, creating high pressure inside the gas pipe 306. Solenoid valve one 307 closes, and solenoid valve two opens. High-pressure gas enters the flexible rod 311 through the air inlet channel 308 within the sliding sleeve 303, causing it to expand. Driven by the rotary drive mechanism 305, the expanded flexible rod 311 rotates along with the limiting rod 301, cleaning the surface of the heat dissipation ring plate 304 and removing dust and dirt. Simultaneously, the expansion and deflation of the flexible rod 311 generate vibration, further shaking off particles adhering to the heat dissipation ring plate 304.

[0032] When the flexible rod 311 is in the retracted state, in conjunction with the frequent reciprocating motion of the sliding sleeve 303, the gas pipe 306 repeatedly draws in and discharges gas, forming a continuous airflow. This airflow not only blows the swept dust out of the system, but also accelerates the gas circulation inside the lamp housing 101, thereby improving heat dissipation efficiency.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
