Description

Technical Field

[0001] This invention belongs to the technical field of coating lighting equipment, specifically referring to an energy-saving coating lamp with adjustable angle. Background Technology

[0002] In painting operations, the angle and intensity of light have a significant impact on work quality and energy consumption. Existing painting lamps often have a fixed structure, making it impossible to flexibly adjust the illumination angle according to the shape of the workpiece or the needs of the operation, resulting in uneven lighting or energy waste. In addition, existing painting equipment lacks effective focusing adjustment functions, making it difficult to increase the light intensity of specific areas without increasing power, thus failing to meet the requirements of fine painting operations.

[0003] Therefore, there is an urgent need to design a painting lamp that can achieve flexible angle adjustment and has energy-saving focusing function. Summary of the Invention

[0004] To address the aforementioned technical problems and overcome the shortcomings of existing technologies, this invention provides an adjustable-angle energy-saving painting lamp. This device achieves unidirectional or antagonistic angle adjustment of the lamp tube through gear and worm gear transmission, and achieves energy-saving effect by focusing light through a reflective film.

[0005] The technical solution adopted in this invention is as follows: This solution provides an adjustable angle energy-saving painting lamp, which consists of a frame, a lamp tube and an adjustment mechanism.

[0006] The frame includes a pair of vertical tubes, a lower horizontal tube fixedly disposed at the lower part of the vertical tubes and connecting the two vertical tubes, an upper horizontal tube fixedly disposed at the upper part of the vertical tubes and connecting the two vertical tubes, and a housing frame cover plate fixedly disposed on the upper wall of the upper horizontal tube. An aviation plug is fixedly disposed on the side wall of the vertical tube, and a wiring terminal is fixedly disposed on the inner wall of the upper horizontal tube, the wiring terminal being electrically connected to the aviation plug.

[0007] Several lamps are rotatably arranged between the vertical tubes. Each lamp consists of a lamp housing, a painted lamp profile fixedly fastened to the inner wall of the lamp housing, a pair of reflective films fixedly fastened to the side wall of the painted lamp profile, an LED light strip fixedly fastened to the inner wall of the painted lamp profile, a painted lamp PC cover fixedly fastened to the side wall of the painted lamp profile, a first lamp end cap fixedly fastened to one side wall of the lamp housing, and a second lamp end cap fixedly fastened to the other side wall of the lamp housing. A conductive connector is rotatably arranged on the inner wall of the first lamp end cap. The conductive connector is electrically connected to the LED light strip and to a terminal block.

[0008] The adjusting mechanism is slidably disposed inside the vertical tube and includes a motor slidably disposed on the lower wall of the upper horizontal tube. A main gear is coaxially fixedly connected to the motor's output shaft. A sliding plate is coaxially sleeved on the motor shaft. Two worm gear holes are provided through the upper and lower walls of the sliding plate. A co-directional adjusting worm and a focusing adjusting worm are respectively rotatably disposed within the worm gear holes. The threads of the co-directional adjusting worm have the same direction of rotation, while the upper and lower threads of the focusing adjusting worm have opposite directions of rotation.

[0009] The second lamp tube end cap is coaxially fixed with a connecting shaft, which is rotatably mounted on the side wall of the vertical tube and extends into the interior of the vertical tube. An adjusting worm gear is coaxially fixed at the end of the connecting shaft, and the adjusting worm gear can selectively mesh with a worm gear in the same direction or a focusing worm gear for transmission. A locking spring is fixedly connected to the inner wall of the vertical tube. A friction locking plate is slidably sleeved on the connecting shaft. The end of the locking spring is fixedly connected to the friction locking plate. The friction locking plate is in contact with the side wall of the adjusting worm gear. An adjusting hole is opened in the side wall of the vertical tube. An unlocking buckle is fixedly mounted on the side wall of the friction locking plate. A sliding buckle is fixedly mounted on the side wall of the sliding plate. The sliding buckle and the unlocking buckle are in abutting engagement. An electric push rod is fixedly mounted on the side wall of the vertical tube and is fixedly connected to the sliding buckle.

[0010] By controlling the extension and retraction of the electric actuator, the sliding buckle moves and presses against the unlocking buckle, forcing the friction locking plate to disengage from the adjusting worm wheel and release the lock. Simultaneously, the sliding buckle causes the sliding plate to move along the vertical tube, selectively pushing the same-direction or opposite-direction adjusting worm gear into the meshing position with the adjusting worm wheel. Subsequently, the motor drives the selected worm gear to rotate, causing the lamp assembly to rotate either in the same direction as a whole or in opposite directions for focusing. Compared with the prior art, the beneficial effects of the present invention are: (1) By setting up a unidirectional adjusting worm and a focusing adjusting worm, and cooperating with the displacement of the sliding plate, the present invention realizes the unidirectional overall adjustment or the opposite-directional focusing adjustment of the lamp tube illumination angle, adapting to different lighting needs; (2) By setting a reflective film on the side wall of the coating lamp profile, the present invention focuses the emitted light into a fixed angle, effectively avoiding energy waste caused by light source scattering and achieving the purpose of energy saving; (3) The present invention drives some lamp tubes to rotate in the opposite direction by focusing and adjusting the worm gear, which can concentrate and reduce the illumination range, improve the illumination intensity within the irradiated range without increasing the power, and improve the efficiency of the coating operation. (4) The present invention utilizes the linkage design of friction locking plate and unlocking buckle to realize automatic unlocking during adjustment and automatic reset locking after adjustment, thus ensuring the stability of the painting lamp angle during operation.

[0015] Example 1: Please refer to Figures 1-4 This embodiment provides an energy-saving painting lamp with an adjustable angle, which consists of a frame, a lamp tube and an adjustment mechanism.

[0016] The frame includes a pair of vertical tubes 1, a lower horizontal tube 2 fixedly installed at the lower part of the vertical tubes 1 and connecting the two vertical tubes 1, an upper horizontal tube 3 fixedly installed at the upper part of the vertical tubes 1 and connecting the two vertical tubes 1, and a housing frame cover plate 4 fixedly installed on the upper wall of the upper horizontal tube 3.

[0017] A plurality of lamp tubes are rotatably arranged between the vertical tubes 1. Each lamp tube consists of a lamp tube housing 7, a painting lamp profile 8 fixedly snapped onto the inner wall of the lamp tube housing 7, a pair of reflective films 9 fixedly snapped onto the side wall of the painting lamp profile 8, an LED light strip 10 fixedly snapped onto the inner wall of the painting lamp profile 8, a painting lamp PC cover 11 fixedly snapped onto the side wall of the painting lamp profile 8, a first lamp tube end cap 12 fixedly set onto one side wall of the lamp tube housing 7, and a second lamp tube end cap 13 fixedly set onto the other side wall of the lamp tube housing 7. A conductive connector 14 is rotatably arranged on the inner wall of the first lamp tube end cap 12. The conductive connector 14 is electrically connected to the LED light strip 10 and the terminal block 6.

[0018] The adjustment mechanism is slidably disposed within the vertical tube 1, including a motor 15 slidably disposed on the lower wall of the upper horizontal tube 3. A main gear 16 is coaxially fixedly connected to the output shaft of the motor 15. A sliding plate 17 is coaxially sleeved on the shaft of the motor 15. Two worm gear holes are provided through the upper and lower walls of the sliding plate 17. A co-rotating adjusting worm 18 and a focusing adjusting worm 19 are respectively rotatably disposed within the worm gear holes. Gears are coaxially fixedly connected to the top ends of the co-rotating adjusting worm 18 and the focusing adjusting worm 19. The gears at the top ends of the co-rotating adjusting worm 18 and the focusing adjusting worm 19 mesh with the main gear 16 for transmission. The co-rotating adjusting worm 18 is a right-handed worm throughout, and the upper part of the focusing adjusting worm 19 is a right-handed worm, while the lower part is a left-handed worm.

[0019] A connecting shaft 20 is coaxially fixed to the second lamp tube end cap 13. The connecting shaft 20 is rotatably mounted on the side wall of the vertical tube 1 and extends into the interior of the vertical tube 1. An adjusting worm gear 21 is coaxially fixed to the connecting shaft 20. The adjusting worm gear 21 can selectively mesh with a co-directional adjusting worm 18 or a focusing adjusting worm 19 for transmission. A locking spring 22 is fixedly connected to the inner wall of the vertical tube 1. A friction locking plate 23 is slidably sleeved on the connecting shaft 20. The end of the locking spring 22 is fixedly connected to the friction locking plate 23. The friction locking plate 23 is in contact with the side wall of the adjusting worm gear 21. An adjusting hole is opened in the side wall of the vertical tube 1. An unlocking buckle 24 is fixedly mounted on the side wall of the friction locking plate 23. A sliding buckle 25 is fixedly mounted on the side wall of the sliding piece 17. The sliding buckle 25 and the unlocking buckle 24 are in abutting engagement. An electric push rod 26 is fixedly mounted on the side wall of the vertical tube 1. The electric push rod 26 is fixedly connected to the sliding buckle 25.

[0020] The specific usage process of this solution is as follows: First, after the frame, lamp tube, and adjustment mechanism are assembled, the aviation plug 5 is powered on, and the LED strip 10 inside the lamp tube is powered on and emits light. The emitted light is reflected by the reflective film 9 fixedly attached to the side wall of the painting lamp profile 8 and emitted through the painting lamp PC cover 11. The emitted light is focused within a fixed angle, effectively avoiding energy waste caused by light source scattering.

[0021] In the default state, the electric actuator 26 and the unlocking buckle 24 are in the middle position, the unidirectional adjusting worm 18 and the focusing adjusting worm 19 are not in contact with the adjusting worm wheel 21, the friction locking plate 23 locks the worm wheel, and the lamp tube angle is fixed.

[0022] When the overall illumination range needs to be adjusted by translation, the control push rod 26 is pushed forward, causing the sliding buckle 25 to move forward. The sliding buckle 25 abuts against the unlocking buckle 24, which is pulled outward. This causes the friction locking plate 23 to move outward against the pressure of the locking spring 22, disengaging the friction locking plate 23 from the side wall of the adjusting worm wheel 21, and putting the adjusting worm wheel 21 in a rotatable state. At this time, the movement of the sliding buckle 25 causes the sliding piece 17 to slide along the inner wall of the vertical tube 1, moving the same-direction adjusting worm 18 to the position where it engages with the adjusting worm wheel 21. By controlling the rotation of the control motor 15, all lamps can be rotated in the same direction through the engagement of the same-direction adjusting worm 18 with the adjusting worm wheel 21, thus achieving overall translation adjustment of the illumination angle.

[0023] When it is necessary to narrow and focus the illumination range, the control actuator 26 pushes the sliding latch 25 backward, causing the focusing adjustment worm gear 19 to move to the position where it engages with the adjusting worm wheel 21. At this time, the motor 15 rotates. Since the focusing adjustment worm gear 19 rotates in opposite directions up and down, the upper lamp tube rotates in the same direction, while the lower lamp tube rotates in the opposite direction to the upper lamp tube. This allows the illumination range to be focused and narrowed, increasing the light intensity within the illuminated area without increasing power.

[0024] After adjustment, the electric push rod 26 returns to its original position, the sliding buckle 25 disengages from the unlocking buckle 24, the unlocking buckle 24 and the friction locking plate 23 are reset under the pressure of the locking spring 22, the friction locking plate 23 is in close contact with the side wall of the adjusting worm wheel 21, and the rotation angle of the adjusting worm wheel 21 and the lamp tube is fixed.

[0025] Example 2: This example is based on Example 1, except that in this example, only the friction locking plate 23 and the adjusting worm gear 21 are retained in the adjusting mechanism. The friction locking plate 23 is fixedly provided with a locking bolt 27 on its side wall, and the vertical tube 1 is rotatably provided with a locking nut 28 on its outer wall. The locking bolt 27 and the locking nut 28 are threadedly connected.

[0026] Please see Figures 1-5 This second embodiment is suitable for application scenarios where frequent adjustment of the illumination angle is not required. During installation, loosen the locking nut 28, manually rotate the lamp tube to adjust the illumination angle, and after adjustment, tighten the locking nut 28. The locking bolt 27 drives the friction locking plate 23 to move towards the adjusting worm gear 21. The friction locking plate 23 is in close contact with the side wall of the adjusting worm gear 21, locking the illumination angle of the lamp tube.

[0027] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
