Description

Technical Field

[0001] The present invention relates to the technical field of lighting fixture manufacturing, and in particular to a novel LED lighting device with a high-temperature protection structure. Background Art

[0002] In high-temperature workshops such as steel mills and smelters, LED lighting fixtures must operate stably and for extended periods in high-temperature environments. Existing LED lighting fixtures generate significant heat when operating at high brightness and power. If this heat cannot be dissipated effectively and promptly, the junction temperature of the LED chip will rise, leading to adverse consequences such as reduced output light power, chip degradation, wavelength "redshift," and shortened device lifespan. Existing LED lighting fixtures often use aluminum or copper substrates as heat dissipation materials, but these materials have limited heat dissipation effectiveness in high-temperature environments. For example, conventional copper / aluminum heat sinks typically only meet heat dissipation requirements of 50 W / cm², which is far from sufficient for high-power LED lamps. Existing heat dissipation methods primarily include heat sinks, natural convection, heat pipes, and fans. However, these methods are not ideal in high-temperature workshops. For example, natural convection is inefficient in high-temperature environments. Natural convection relies primarily on density differences in fluids (such as air), which are caused by temperature differences. In high-temperature environments, the ambient temperature is already high, and the temperature difference between the heat sink and the environment decreases, weakening the driving force of natural convection and significantly reducing the heat dissipation effect. Summary of the Invention

[0003] The object of the present invention is to provide a new LED lighting device with a high-temperature protection structure to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, a new type of LED lighting device with a high-temperature protection structure is provided, including a lamp holder, an integrated circuit arranged inside the lamp holder, and the integrated circuit is responsible for controlling the operation of the LED lighting device.

The heat dissipation structure rotates and blows out airflow upward to take away the heat generated by the lamp holder. A dust cleaning structure is provided below the heat dissipation structure, and the dust cleaning structure rotates to scratch the side wall of the lamp body. When the dust cleaning structure rotates, the heat dissipation structure is deflected and generates a downward-blowing airflow to blow away the dust scratched from the side wall of the lamp body by the dust cleaning structure.

[0008] As a further improvement of the present technical solution, the dust cleaning structure includes a sliding seat that is slidably sleeved on the bottom of the main shaft, a sliding plate is rotatably sleeved on the bottom of the sliding seat, a plurality of grooves are provided at the bottom of the lower sliding ring, and a plurality of hemispheres are fixedly installed on the top of the sliding seat. The sliding plate pushes the sliding seat to slide upward and enables the hemispheres to be embedded in the grooves. The upper fixed ring rotates through the main shaft and the lower sliding ring to drive the sliding seat to rotate around the axis of the lamp body.

[0009] As a further improvement of the present technical solution, a number of L-shaped rods are fixedly installed in a circular array on the side wall of the sliding seat, and a brush is rotatably sleeved on the bottom of the L-shaped rod.

[0027] Example 1

[0028] See also Figures 1-8 As shown, the purpose of this embodiment is to provide a new type of LED lighting device with a high-temperature protection structure, including a lamp holder 4, an integrated circuit is arranged inside the lamp holder 4, the lamp holder 4 is responsible for controlling the operation of the LED lighting device, a lamp body 3 is installed below the lamp holder 4, and a heat dissipation structure 1 is arranged above the lamp holder 4. The heat dissipation structure 1 rotates and blows out airflow upward to take away the heat generated by the lamp holder 4, thereby preventing the lamp body 3 from overheating and extending the service life of the LED lighting device. A dust cleaning structure 2 is arranged below the heat dissipation structure 1, and the dust cleaning structure 2 rotates to scratch the side wall of the lamp body 3. When the dust cleaning structure 2 rotates, the heat dissipation structure 1 is deflected and generates a downward blowing airflow to blow away the dust scratched off the side wall of the lamp body 3 by the dust cleaning structure 2, thereby preventing the dust from re-adhering to the lamp body 3 of the bulb, thereby ensuring the continuity of the lighting effect.

[0029] The heat dissipation structure 1 includes an upper fixed ring 11, and a plurality of fan blades 17 are arranged in a circumferential array on the side wall of the upper fixed ring 11. A motor 5 fixedly mounted on the lamp holder 4 is arranged below the upper fixed ring 11. The upper end of the rotating shaft of the motor 5 is fixedly mounted with a main shaft 16, and the upper end of the main shaft 16 is fixedly mounted on the upper fixed ring 11. The motor 5 drives the main shaft 16 and the upper fixed ring 11 to rotate through the rotating shaft, so that the plurality of fan blades 17 rotate. The rotating plurality of fan blades 17 stirs the air and generates upward or downward airflow. The upward airflow takes away the heat of the lamp holder 4 upward, effectively reducing the temperature of the lamp holder 4, preventing it from overheating, and extending the service life of the LED lighting device. The downward airflow blows the dust on the side wall of the bulb body 3 downward, keeping the bulb body 3 clean and improving the lighting effect.

[0030] The fan blade 17 is fixedly connected to the end close to the upper fixing ring 11 with a sleeve 13, and a rotating positioning core 111 is rotatably installed inside the end of the sleeve 13 close to the upper fixing ring 11. The rotating positioning core 111 is fixedly installed on the side wall of the upper fixing ring 11 at the end away from the fan blade 17. This structural design allows the fan blade 17 to deflect around the upper fixing ring 11 through the cooperation of the sleeve 13 and the rotating positioning core 111, thereby realizing multi-directional airflow generation. These airflows can not only carry away the heat generated by the lamp holder 4 upward, effectively reduce the temperature of the lamp holder 4, prevent damage caused by overheating, and extend the service life of the LED lighting device, but also blow the dust on the side wall of the bulb body 3 downward, keep the bulb body 3 clean, and improve the lighting effect.

[0031] A ball head rod 131 is fixedly installed on the side wall of the sleeve 13 near one end of the upper fixed ring 11. The head of the ball head rod 131 is set to be spherical, so that the ball head rod 131 can swing in multiple directions in the subsequent structure, increasing the movement flexibility of the fan blade 17. A lower sliding ring 12 is provided on the sliding sleeve of the side wall of the main shaft 16. The lower sliding ring 12 and the main shaft 16 are connected by several splines set on the side wall of the main shaft 16. Through the spline connection, the main shaft 16 can drive the lower sliding ring 12 to rotate to achieve synchronous movement.

[0032] Several connecting blocks 121 are fixedly connected to the side wall of the lower sliding ring 12, and a hinged rod 14 is fixedly connected to one side of the connecting block 121. A push rod 15 is rotatably sleeved on the end of the hinged rod 14 away from the connecting block 121, and the spherical head of the ball head rod 131 is rotatably installed on the top of the push rod 15. When the lower sliding ring 12 slides up and down, the connecting block 121, the hinged rod 14 and the push rod 15 push the ball head rod 131 to swing. The swinging ball head rod 131 drives the fan blades 17 to deflect around the upper fixed ring 11 through the sleeve 13, and then generates airflows in different directions through the several deflected fan blades 17. The upward airflow takes away the heat from the lamp holder 4 upward, effectively reducing the temperature of the lamp holder 4, preventing damage caused by overheating, and extending the service life of the LED lighting device. The downward airflow blows the dust on the side wall of the bulb body 3 downward, keeping the bulb body 3 clean and improving the lighting effect.

[0033] The dust cleaning structure 2 includes a sliding seat 22 that is slidably sleeved on the bottom of the main shaft 16. The bottom of the sliding seat 22 is rotatably sleeved with a sliding plate 21, so that the sliding plate 21 can slide up and down under the drive of the sliding seat 22, thereby increasing the flexibility of the dust cleaning structure 2. The bottom of the lower sliding ring 12 is provided with a plurality of grooves, and the top of the sliding seat 22 is fixedly installed with a plurality of hemispheres 221. The sliding plate 21 pushes the sliding seat 22 to slide upward and makes the hemispheres 221 fit in the grooves. This fitting design ensures a stable connection between the sliding seat 22 and the lower sliding ring 12, so that the sliding seat 22 can rotate with the lower sliding ring 12. The rotation of the upper fixed ring 11 drives the sliding seat 22 to rotate around the axis of the lamp body 3 through the main shaft 16 and the lower sliding ring 12, so that the dust cleaning structure 2 can fully cover the surface of the lamp body 3 of the bulb and perform effective dust cleaning operations.

[0034] A number of L-shaped rods 23 are fixedly installed in a circular array on the side wall of the sliding seat 22, so that the L-shaped rods 23 can be evenly distributed around the sliding seat 22, ensuring the comprehensiveness and uniformity of the dust cleaning operation. The bottom of the L-shaped rod 23 is rotatably sleeved with a brush 24, and the brush 24 contacts the side wall of the lamp body 3. The rotating sliding seat 22 drives the brush 24 to rotate around the lamp body 3 through the L-shaped rod 23, so that the several brushes 24 rotate and scratch the side wall of the lamp body 3. This design can not only effectively remove dust on the side wall of the bulb body 3, keep the bulb body 3 clean, and improve the lighting effect, but also reduce the re-adhesion of dust through the scratching action, ensuring the continuity of the lighting effect.

[0035] One side of the motor 5 is provided with an electric cylinder 6 fixedly mounted on the lamp holder 4. The piston rod of the electric cylinder 6 is connected to the bottom of the sliding plate 21. The electric cylinder 6 drives the sliding plate 21 to slide up and down through the piston rod, thereby realizing dynamic adjustment of the cleaning structure 2. Two balance bars 25 are fixedly installed under the sliding plate 21. The two balance bars 25 and the electric cylinder 6 are arranged in a ring array around the motor 5, ensuring the balance and stability of the sliding plate 21 when sliding up and down, thereby improving the reliability of the entire structure.

[0036] The electric cylinder 6 drives the sliding plate 21 to slide up and down through the piston rod. The upward sliding plate 21 is connected to the lower sliding ring 12 through the hemisphere 221 and pushes the lower sliding ring 12 upward, so that the plurality of fan blades 17 blow out airflow downward, and drive the plurality of brushes 24 to rotate around the lamp body 3, blowing away the scratched dust downward. This process not only keeps the lamp body 3 clean and improves the lighting effect, but also prevents dust from re-attaching through the downward airflow, thereby ensuring the continuity of the lighting effect; the downward sliding plate 21 drives the sliding seat 22 to disengage from the groove through the sliding plate 21, so that the plurality of brushes 24 stop rotating and drive the lower sliding ring 12 away from the upper fixed ring 11, so that the plurality of fan blades 17 blow out airflow upward, taking away the heat of the lamp holder 4. This process effectively reduces the temperature of the lamp holder 4, prevents damage caused by overheating, and extends the service life of the LED lighting device.

[0037] When the present embodiment is used, the lamp body 3 is installed below the lamp holder 4, and the electric cylinder 6 drives the sliding plate 21 to slide up and down through the piston rod. When the lamp body 3 is illuminated, the sliding plate 21 slides downward and the hemisphere 221 is disengaged from the groove, so that the plurality of brushes 24 stop rotating and drive the lower sliding ring 12 away from the upper fixed ring 11, so that the plurality of fan blades 17 blow air upward to take away the heat of the lamp holder 4. This process effectively reduces the temperature of the lamp holder 4, prevents damage caused by overheating, and prolongs the service life of the LED lighting device. When the lamp body 3 is not lighting, the upward sliding plate 21 is connected to the lower sliding ring 12 through the hemisphere 221 and pushes the lower sliding ring 12 upward, so that the plurality of fan blades 17 blow out airflow downward, and at the same time the sliding seat 22 rotates around the bulb body 3, driving the plurality of brushes 24 to scrape the side wall of the bulb body 3, and blow away the scraped dust downward. This process not only keeps the bulb body 3 clean and improves the lighting effect, but also prevents dust from re-attaching through the downward blowing airflow, thereby ensuring the continuity of the lighting effect.
