Description

Technical Field

[0001] This invention relates to the field of LED lighting fixture technology, specifically an LED lighting fixture with a cooling fan. Background Technology

[0002] Currently, embedded LED lighting fixtures are widely used in commercial, office, and indoor space lighting due to their advantages of strong concealment and adaptability to various decoration scenarios.

[0003] Existing traditional embedded LED lighting fixtures have limited functions, providing only basic lighting. During operation, the light source generates a lot of heat, and the embedded, enclosed installation structure has poor heat dissipation, making it easy for heat to accumulate. Long-term use can lead to light source attenuation and component aging, affecting the lifespan and safety of the lighting fixtures.

[0004] Some traditional lighting fixtures have a single angle adjustment method and a limited adjustment range, making it impossible to achieve multi-directional and large-angle lighting and air supply adjustment, and thus only suitable for a limited range of scenarios.

[0005] The existing integrated fan lighting fixtures have an imperfect structural design, lacking automatic alignment and self-adaptive retraction and extension functions. The fixtures are prone to shifting and jamming during storage, and the retraction and extension operations rely on manual operation, resulting in poor ease of use. Furthermore, the equipment is prone to structural interference and excessive noise during operation, making it unsuitable for diverse new usage scenarios such as plant cultivation, commercial shops, and public rest spaces, thus limiting its market applicability.

[0006] Based on this, the present invention provides an LED lighting fixture with a cooling fan to solve the above problems. Summary of the Invention

[0007] In view of the above situation and to overcome the defects of the prior art, the present invention provides an LED lighting fixture with a cooling fan. The present invention has an ingenious structure and focuses on practicality, effectively solving the technical problems of limited adjustment range, poor operation convenience, and inconvenient storage and operation.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] An LED lighting fixture with a cooling fan includes a main body, a rotating frame rotatably connected to the main body, brackets fixedly installed on both sides of the rotating frame, a lamp body mounted on the brackets, a rear cover fixedly installed above the lamp body, and a fan-bladed lamp fixedly installed below the rear cover and placed inside the lamp body. Sliding blocks are slidably connected to both sides of the brackets, and the lamp body is rotatably connected to the inner sides of the two sliding blocks, so that the lamp body can rotate around the sliding blocks, slide on the brackets, and rotate by the rotating frame.

[0010] Preferably, the rotation angle range of the rotating frame is 0-355°, and the rotation angle range of the lamp body is 0-130°.

[0011] Preferably, a fixing ring is fixedly installed inside the body, a rotating ring is slidably connected inside the fixing ring, and two symmetrically distributed hinge frames and limiting baffles are fixedly installed inside the rotating ring. A correction block that can contact the rear cover and the limiting baffle is fixedly installed on one side of each of the two hinge frames.

[0012] Preferably, two sets of symmetrically distributed limiting blocks that can limit the position of the bracket are fixedly installed on the inner side of the rotating ring.

[0013] Preferably, an electric push rod is fixedly installed at the bottom of the bracket, and a lower pressure plate that can contact the rear cover is fixedly installed at the bottom end of the output shaft of the electric push rod. A sliding frame is fixedly installed on one side of the lower pressure plate.

[0014] Preferably, two fixed frames are fixedly installed below the bracket, and a sliding frame is slidably connected inside each of the two fixed frames. An extension frame is fixedly installed below the sliding frame, and a connecting hook that can contact the rear cover is rotatably connected to the inner side of the extension frame. A reset torsion spring is installed between the connecting hook and the extension frame.

[0015] Preferably, a rotating arm is rotatably connected inside the sliding frame, a fixed rod is fixedly installed inside the sliding frame, a swing arm is slidably connected to the surface of the fixed rod and hinged to the rotating arm, a pushed rod is fixedly installed on the swing arm, connecting arms are fixedly installed on both sides of the bottom end of the rotating arm, an extension arm is slidably connected to the connecting arm and fixedly installed above the connecting hook, and a pushing block that can contact the pushed rod is fixedly installed inside the fixed frame.

[0016] Preferably, a power supply is fixedly installed on the top of the body, and two symmetrically distributed spring pieces are fixedly installed on the surface of the body.

[0017] The present invention has the following technical advantages.

[0018] 1. This invention combines a 355° rotating frame structure with a 130° rotating lamp body structure to form a dual-angle adjustment structure, which greatly expands the range of light radiation adjustment of the lamp and realizes multi-directional angle adjustment to adapt to various lighting scenarios. By integrating a fan-blade lamp structure inside the lamp body, LED lighting and fan blade air supply functions are combined, which can accelerate the air flow around the lamp and remove the heat of the lamp body in time, realizing the lamp's self-heating.

[0019] 2. The present invention uses a combination structure of a fixed ring, a rotating ring, a limiting block, a correcting block and a limiting baffle to automatically correct and align the angle of the cover and the lamp body during the lamp storage process, avoiding storage offset and jamming, and improving storage accuracy and structural fit stability.

[0020] 3. This invention utilizes an electric push rod at the bottom of the bracket, combined with a sliding frame and a lower pressure plate to form a push-pull drive structure, enabling the electric initial extension and final retraction of the lamp body. This solves the problem of difficult operation due to limited hand contact surface during the initial extension and final retraction of the lamp body. Through the linkage structure of the fixed frame, push block, pushed rod, rotating arm, swing arm, and reset torsion spring, the connecting hook can automatically switch between disengaged and engaged states according to the extension and retraction conditions, avoiding structural interference and ensuring smooth and reliable lamp extension and retraction, while reducing structural wear and the probability of failure.

[0032] The foregoing and other technical contents, features and effects of the present invention are described in conjunction with the appendix below. Figures 1 to 8 The detailed description of the embodiments will make this clear. All references to the following embodiments are made with reference to the accompanying drawings.

[0033] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0034] This invention relates to an LED lighting fixture with a cooling fan, comprising a body 1, which can be concealed within the ceiling to achieve a largely hidden appearance. A rotating frame 11 is rotatably connected to the body 1. This rotation is damped and will not rotate under normal conditions, but will rotate when force is applied. The rotating frame 11 is a hollow circular frame, and its hollow interior can be used for wiring. Supports 7 are fixedly installed on both sides of the rotating frame 11. The supports 7 are L-shaped, and one side of the supports 7 has a through groove with round ends and a rectangular middle section.

[0035] The bracket 7 is equipped with a lamp body 5, which is cylindrical. A rear cover 10 is fixedly installed on the top of the lamp body 5. The rear cover 10 is a mesh cover. A fan-bladed lamp 8 is fixedly installed inside the lamp body 5 below the rear cover 10. The fan-bladed lamp 8 is a structure composed of an LED lamp and a rotating fan blade on its surface. The fan-bladed lamp 8 is connected to a power supply and a controller.

[0036] The bracket 7 is slidably connected to a sliding block 6. This sliding is damped sliding and will not slide in a natural state. Specifically, the sliding block 6 is damped and installed on the through groove on the bracket 7 by two bolts and a pad. The pad can slide on the through groove, thereby driving the sliding block 6 to slide up and down. The two bolts can be adjusted on the sliding block 6, thereby adjusting the maximum moving distance of the lamp body 5.

[0037] The lamp body 5 is rotatably connected to the inside of two sliding blocks 6. This rotation is a damped rotation and will not rotate in a natural state. The rotation angle range of the rotating frame 11 is 0-355°, and the rotation angle range of the lamp body 5 is 0-130°. By setting two rotation angle limits, the maximum adjustable radiation range can be maintained while ensuring the stability of the equipment and minimal noise.

[0038] The lamp body 5 can rotate around the sliding block 6, slide on the bracket 7, and rotate by the rotating frame 11.

[0039] In this embodiment, when using the fan-bladed light 8, the operation of the fan-bladed light 8 can be directly controlled by the power supply, controller, and switch to turn on the LED light and drive the fan blades to rotate, blowing the wind outward. During use, when it is necessary to adjust the angle, the lamp body 5 can be manually rotated. The lamp body 5 rotates on the sliding block 6 to adjust the angle. Then, the lamp body 5 can be held and rotated horizontally. The lamp body 5 drives the rotating frame 11 to rotate, so as to achieve adjustment as needed.

[0040] Stretching and pushing the lamp body 5 allows the lamp body 5 to move the sliding block 6 within the bracket 7, enabling it to be stored and pulled out.

[0041] As an example, a fixed ring 12 is fixedly installed on the inner side of the main body 1, and a rotating ring 13 is slidably connected inside the fixed ring 12. An annular groove is machined on the inner ring of the fixed ring 12, and the rotating ring 13 is adapted to the annular groove. Two symmetrically distributed hinge frames 16 and a limiting baffle 17 are fixedly installed on the inner side of the rotating ring 13. The limiting baffle 17 is a rectangular plate, which can limit the rotation angle of the correction block 15 to a certain extent. A correction block 15 that can contact the rear cover 10 and the limiting baffle 17 is fixedly installed on one side of each of the two hinge frames 16. The correction block 15 is a right-angled trapezoidal metal block.

[0042] The hinge frame 16 includes a hinge base fixed on the rotating ring 13. A hinge rod is hinged to the front side of the hinge base, and the hinge rod fixes the straightening block 15. Therefore, the straightening block 15 can rotate. Two sets of symmetrically distributed limiting blocks 14 that can limit the position of the bracket 7 are fixedly installed on the inner side of the rotating ring 13. Through the two sets of limiting blocks 14, the rotating ring 13 can rotate with the bracket 7, so that the contact position between the straightening block 15 and the rear cover 10 always corresponds.

[0043] In this embodiment, when the lamp body 5 needs to be stored, the lamp body 5 can be manually adjusted to the approximate storage angle, and then the lamp body 5 is pushed back into the body 1. When it is pushed to a certain extent, the rear cover 10 above the lamp body 5 first contacts the right-angled trapezoidal inclined surface of the correction block 15, and then pushes the correction block 15 to rotate in the opposite direction. The two interact to correct the rear cover 10 and the lamp body 5 to a certain extent until the state of the correction block 15 no longer changes when it rotates to contact the limiting baffle 17. Otherwise, the final correction process of the rear cover 10 and the lamp body 5 is achieved. When the limiting baffle 17 contacts the correction block 15, the correction block 15 is kept in a vertical state, that is, the correction surface of the correction block 15 is kept parallel to the rear cover 10.

[0044] As an example, an electric push rod 9 is fixedly installed at the bottom of the bracket 7. The electric push rod 9 is connected to a power supply and a controller. A lower pressure plate 29 that can contact the rear cover 10 is fixedly installed at the bottom of the output shaft of the electric push rod 9. A sliding frame 19 is fixedly installed on one side of the lower pressure plate 29.

[0045] Two symmetrically distributed fixed frames 18 are fixedly installed below the bracket 7. Each fixed frame 18 has a sliding frame 19 that is fixedly installed on one side of the lower pressure plate 29. The fixed frame 18 has an irregularly shaped sliding groove that runs vertically through it. The sliding frame 19 matches this sliding groove. An extension frame 25 is fixedly installed below the sliding frame 19. The extension frame 25 has a connecting hook 27 that can rotatably connect to the rear cover 10. The connecting hook 27 is a structure composed of a rectangular block and a right-angled triangular block. One right-angled face of the right-angled triangle of the connecting hook 27 can contact the rear cover 10. A reset torsion spring 26 is sleeved between the connecting hook 27 and the extension frame 25.

[0046] In this embodiment, in the initial stage, the lamp body 5 is stored inside the body 1. There is no space to grab the lamp body 5 by hand, and it is quite troublesome to pull it out manually. Therefore, it is necessary to initially push out the lamp body 5. First, the electric push rod 9 is driven downward by controlling it. The switch position of the electric push rod 9 is not limited and can be wirelessly connected. The electric push rod 9 drives the lower pressure plate 29 to push the lamp body 5 down, thus realizing the initial push out of the lamp body 5.

[0047] When the lamp body 5 is not in use, the surface of the lamp body 5 will heat up to a certain extent due to heat conduction after the lamp body 8 has been working for a period of time. Initially, the lamp body 5 can be manually pushed to retract. Since the lamp body 5 has a large external contact area, as more and more of the lamp body 5 enters the main body 1, it becomes difficult to retract by hand. Therefore, after retracting to a certain extent by hand, the electric push rod 9 is controlled to retract, which drives the lower pressure plate 29, the sliding frame 19 and the connecting hook 27 to rise. The connecting hook 27 hooks the rear cover 10, which drives the lamp body 5 to rise and achieve the final retraction.

[0048] As one embodiment, a rotating arm 22 is rotatably connected inside the sliding frame 19. A fixed rod 21 is fixedly installed on the inner side of the sliding frame 19. A swing arm 30 is slidably connected to the surface of the fixed rod 21 and hinged to the inner side of the upper end face of the rotating arm 22. The swing arm 30 has a rectangular structure, and a groove with round ends and a rectangular middle is opened on the surface of the swing arm 30. The groove of the swing arm 30 matches the size of the fixed rod 21. A push rod 20 is fixedly installed on one side of the swing arm 30. The push rod 20 is a cylindrical block with a round end. 2. The same connecting arm 23 is fixedly installed on both sides of the bottom end. An extension arm 24 is slidably connected to the connecting arm 23 and fixedly installed above the connecting hook 27. The extension arm 24 is a rectangular structure with circular grooves at both ends and a rectangular groove in the middle on its surface. The structure of the connecting arm 23 includes a rectangular plate and a pin fixedly installed on one side of it, which is slidably connected to the extension arm 24. A push block 28 that can contact the pushed rod 20 is fixedly installed inside the fixing frame 18. The push block 28 is a trapezoidal block, and its inclined surface can contact the pushed rod 20.

[0049] In this embodiment, when the lamp body 5 is initially pushed, the sliding frame 19 is controlled to descend, which drives the fixed rod 21 and the rotating arm 22 to descend as well. After descending to a certain height, when the pushed rod 20 contacts the pushing block 28, the fixedly placed pushing block 28 will push the pushed rod 20 and the swing arm 30 to rotate clockwise, thereby driving the rotating arm 22, which is hinged to the swing arm 30, to rotate counterclockwise. The counterclockwise rotation of the rotating arm 22 will drive the extension arm 24 and the connecting hook 27 to rotate clockwise, driving the connecting hook 27 to be in a non-vertical state, which is called the disengaged state.

[0050] When the lamp body 5 is finally stored, the sliding frame 19 is raised. When the push rod 20 is not in contact with the push block 28, the reset torsion spring 26 drives the connecting hook 27 to return to the vertical state. This is called the hook state. The state is automatically adjusted according to the needs of pushing out or storing the lamp body 5.

[0051] As an example, a power supply 3 is fixedly installed on the top of the main body 1, two symmetrically distributed spring pieces 2 are fixedly installed on the surface of the main body 1, and an outer cover 4 is fixedly installed on the bottom of the lamp body 5.

[0052] Working principle:

[0053] S1. When the lamp body 5 is in the extended state, the electric push rod 9 extends, driving the lower pressure plate 29 and the sliding frame 19 to move downwards synchronously along the slide groove of the fixed frame 18. During the downward movement of the sliding frame 19, the rotating arm 22 moves downwards synchronously, causing the pushed rod 20 to contact the trapezoidal push block 28 on the inner side of the fixed frame 18. Through the pushing action of the inclined surface of the push block 28, the swing arm 30 is driven to slide along the fixed rod 21 and rotate clockwise. The rotating arm 22 rotates counterclockwise, and then through the transmission of the connecting arm 23 and the extension arm 24, the connecting hook 27 rotates clockwise and switches to the disengaged state, thus completing the smooth initial extension of the lamp body 5. After that, the lamp body 5 is pulled out to the required position by hand.

[0054] S2. When the lamp is working normally, the controller starts the fan-bladed lamp 8 to light up the LED light source and achieve lighting operation. At the same time, the fan blades are driven to rotate, which accelerates the air circulation around the lamp body 5.

[0055] When the angle of the lamp body 5 needs to be adjusted, the lamp body 5 is manually rotated. The lamp body 5 rotates on the sliding block 6 to adjust the angle. Then, the lamp body 5 can be held and rotated horizontally. The lamp body 5 drives the rotating frame 11 to rotate, so as to achieve the adjustment as needed. During this process, the lamp body 5 drives the bracket 7 to rotate. The bracket 7 drives the limit block 14 to move together, so it can be ensured that the correction block 15 always corresponds to the position of the rear cover 10.

[0056] The rotation angle range of the rotating frame 11 is 0-355°, and the rotation angle range of the lamp body 5 is 0-130°, which has the ability to rotate in all directions and complete the adjustment of the lighting position in a wide range and at multiple angles.

[0057] S3. When storing the lamp body 5, first manually push the lamp body 5 into the body 1 part of the interior. The rear cover 10 moves with the lamp body 5 and presses the trapezoidal inclined surface of the correction block 15, driving the correction block 15 to rotate. With the limiting action of the limiting baffle 17, the lamp body 5 and the rear cover 10 are automatically corrected and aligned. Then, by controlling the electric push rod 9 to retract, the sliding frame 19 is driven to rise. When the pushed rod 20 is not in contact with the trapezoidal push block 28, the reset torsion spring 26 drives the connecting hook 27 to rotate to the hook state. At this time, the connecting hook 27 is hooked on the rear cover 10. During the rising process, the rear cover 10 and the lamp body 5 are completely stored inside the body 1.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
