Description

Technical Field

[0001] This invention relates to the field of lighting technology, and in particular to an outdoor moisture-proof lighting device for building service engineering. Background Technology

[0002] Construction engineering, a part of building construction, refers to the physical engineering project formed through the construction of various buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. Construction projects include factories, theaters, hotels, shops, schools, hospitals, and residences, meeting people's needs for production, living, learning, and public activities. With the rapid development of the construction industry, construction often takes place at night; therefore, lighting is required at construction sites.

[0003] For example, a building lighting device, as disclosed in Chinese Patent Publication No. CN221839641U, includes a base, a lifting plate, a lifting assembly, casters, a vertical cylinder, a sliding plate, a connecting rod, a mounting block, a lighting lamp, and a sliding component. The lifting plate is slidably connected to the base. The lifting assembly is mounted on the base and drives the lifting plate to slide up and down. The casters are fixedly mounted on the lifting plate. The vertical cylinder is fixedly connected to the base. The sliding plate is slidably connected inside the vertical cylinder. The connecting rod is fixedly connected to the sliding plate and extends through the vertical cylinder to the outside. The mounting block is fixedly connected to the connecting rod. The lighting lamp... The device is fixedly installed on the mounting block. The sliding component is set on the upright cylinder and is used to drive the sliding plate to slide. The lifting component drives the lifting plate to slide downward, causing the caster wheels to move downward until they contact the ground, thus moving the position of the base and the position of the lighting lamp. The sliding component drives the sliding plate to slide, which in turn moves the connecting rod, which in turn moves the mounting block, thus adjusting the height of the lighting lamp. Therefore, this building lighting equipment facilitates the adjustment of the position and height of the lighting lamp, and can be adjusted according to specific needs, thereby illuminating the building operation area as much as possible with fewer lighting lamps.

[0004] The existing technical reference documents suggest that the position and height of the lighting lamps can be adjusted to increase the lighting area. However, such a design makes it inconvenient to adjust the light output focal length, creates obvious dark areas, and fails to meet the different lighting needs at different distances on the engineering site, thus affecting the lighting effect. Summary of the Invention

[0005] To solve the above technical problems, the present invention is implemented through the following technical solution: An outdoor moisture-proof lighting device for building service engineering includes: The machine body and the bracket fixedly connected to the top side of the machine body. The bottom of the machine body is equipped with rolling wheels. A right-angled notch is opened on the surface of the machine body at the end away from the bracket. A flexible cover is fixedly connected to the top of the machine body near the right-angled notch. The flexible cover can block rain and prevent rainwater from entering the interior of the machine body. The lighting mechanism includes a support tube, a driver, and a dehumidifying chamber. The support tube is rotatably mounted at a right-angled notch on the top of the machine body. The driver is fixedly mounted on the side of the top of the machine body. The dehumidifying chamber is fixedly mounted on the top of the support tube. A conical reflector is hinged to the side of the top of the support tube via a U-shaped frame. A transparent cover is installed at the port of the conical reflector to protect it. An electric telescopic rod is hinged to the surface of the support tube near the conical reflector. A light output focus adjustment component is installed at the top of the support tube. A heat-conducting plate is fixedly installed in the middle of the surface of the dehumidifying chamber to dissipate heat from the chamber and achieve a cooling effect. The light output focal length adjustment assembly includes an arc-shaped component and a circular tube. The bottom of the arc-shaped component is fixedly installed to the top of the support tube. The circular tube is slidably mounted on the end of the conical reflector away from the transparent cover. The circular tube can conduct heat out of the conical reflector, cooling the inside of the conical reflector. An LED is installed at the end of the circular tube, and the LED is installed inside the conical reflector. A gradually deformed groove is formed in the middle of the arc-shaped component. A roller is rolled on the surface of the circular tube near the inner cavity of the gradually deformed groove. An elastic element is fixedly connected between the end face of the conical reflector and the surface of the circular tube, near the circular tube. The arc-shaped component and elastic component are installed inside the moisture-proof box. A flexible sealing plate is fixedly installed between the surface of the conical reflector and the surface of the moisture-proof box. The lamp beads are supported by the round tube and powered on, so that the lamp beads can emit light. The light is reflected by the conical reflector to illuminate the construction site and achieve the lighting effect. By extending and retracting the extension end of the electric telescopic rod, a pushing force and a pulling force can be applied to the electric telescopic rod, so that the conical reflector can be rotated to adjust the angle, thereby increasing the illumination range of the construction site. A moisture-proof component is installed at the bottom of the surface of the support tube, and an auxiliary mechanism is installed at the bottom of the inner cavity of the machine body near the wheel.

[0006] Furthermore, the support tube passes through the top of the flexible cover, which is made of rubber. The flexible cover itself is flexible, preventing structural jamming when the support tube is rotated to adjust its angle, thus ensuring smooth rotation and adjustment. The connecting shaft on the surface of the support tube is fixedly installed with the output end of the driver via a coupling. The telescopic rod of the electric telescopic rod is hinged to the bottom of the conical reflector. The electric telescopic rod is a moisture-proof and rainproof telescopic rod.

[0007] Furthermore, the bottom end of the support tube passes through the middle of the right-angled notch, the electric telescopic rod is installed at an angle, and the heat-conducting plate penetrates the dehumidifying box and extends into its interior.

[0008] By utilizing the elastic element to continuously apply an elastic force to the circular tube, the outer surface of the roller can be tightly fitted with the inner surface of the gradually deforming groove. When the angle of the conical reflector is adjusted, the conical reflector will drive the circular tube to rotate and adjust the angle together. Through the gradually deforming groove, a pushing force is applied to the roller, and the circular tube will drive the lamp beads to move linearly inside the conical reflector, adjusting the light output focal length and realizing a smooth switch between focused and diffused light spots. This meets the different lighting needs at the engineering site at different distances, increases the illuminated area, and eliminates obvious dark areas.

[0009] Furthermore, the circular tube passes through the center of the elastic element, and the axis of the circular tube coincides with the axis of the conical reflector. The outer circular surface of the roller fits against the inner side of the gradually deformed groove. The circular tube passes through the center of the flexible sealing disc, which is made of rubber. The flexible sealing disc itself is flexible and can block rain, preventing rainwater from entering the interior. At the same time, when the conical reflector is rotated to adjust the angle, it avoids structural jamming, making the rotation and adjustment of the conical reflector smooth.

[0010] After the LED lights illuminate the construction site, the driver output can rotate the support tube clockwise, causing the conical reflector to tilt towards the bracket. The bracket supports the support tube, allowing it to fold, lowering the center of gravity of the lighting equipment and making it easy to move.

[0011] Furthermore, the moisture-proof component includes a suction fan, a right-angle elbow, and a flexible hose. The suction fan is fixedly installed at the bottom of the support pipe surface. The top end of the right-angle elbow is connected to the bottom end of the support pipe. The flexible hose is installed at the top of the suction fan. A bent pipe is fixedly connected to the surface of the right-angle elbow. The top end of the bent pipe is connected to the air outlet of the suction fan. The bottom end of the bent pipe passes through the right-angle elbow and extends into the interior of the device. A conical hopper is fixedly connected to the inner wall of the right-angle elbow. A guide rod is slidably connected to the surface of the conical hopper. A conical plug is fixedly connected to the end of the guide rod away from the conical hopper. A dehumidifier is fixedly installed on the side of the device surface.

[0012] Furthermore, the hose passes through the top of the flexible cover cavity, the hose is curved, and the air inlet end of the hose is connected to the top of the dehumidifier.

[0013] Furthermore, the air outlet at the bottom of the bent pipe is connected to the conical hopper, and the conical plug is installed at the same height as the conical hopper.

[0014] Furthermore, the auxiliary mechanism includes an I-shaped slider and a supporting connecting rod. The I-shaped slider is slidably installed at the bottom of the machine body cavity. The bottom end of the supporting connecting rod is fixedly installed to the top of the I-shaped slider. A plate is fixedly connected to the top of the supporting connecting rod. An air jet is fixedly installed at the middle of the surface of the plate. A horn-shaped limiting bucket is installed on the surface of the plate away from the air jet. A brake plate is fixedly connected to the bottom of the I-shaped slider near the wheel. A flexible strip is fixedly connected to the surface of the brake plate. The horn-shaped limiting bucket... A ball-head actuating component is fixedly connected at the center, and the support tube is in a vertical position, raising the overall center of gravity of the lighting equipment. The air outlet at the bottom of the right-angle bend is inserted into the inside of the horn-shaped limiting bucket, and the bottom end of the right-angle bend applies a pushing force to the right side to the horn-shaped limiting bucket. Under the sliding connection of the I-shaped slider, the brake plate drives the flexible strip to move closer to the wheel. The brake plate presses the flexible strip, making the flexible strip fit against the surface of the wheel, which increases the friction and brakes the wheel, preventing the lighting equipment from moving randomly and making the whole system more stable.

[0015] Furthermore, the support rods are installed at an angle, and there are two support rods, which are symmetrically installed along the horn-shaped limiting bucket, and the horn-shaped limiting bucket is connected to the jet head.

[0016] By using the ball-head actuator to apply a counter-thrust to the conical plug, and under the guidance of the guide rod, the conical plug moves away from the air outlet of the right-angle bend, thus opening the air outlet of the right-angle bend and spraying gas into the machine body through the jet nozzle.

[0017] Furthermore, the brake plate is installed at an angle, and the flexible strip is evenly distributed on the surface of the brake plate. The flexible strip is made of rubber. The dehumidifier dries the humid air and uses the suction of the fan. With the connection of the hose, the dried air in the dehumidifier is sucked out and blown out through the bend pipe into the right-angle bend. The dried gas is then blown into the jet head through the horn-shaped limiting bucket. The jet head blows the gas out, causing the air in the machine to be blown, thereby creating gas circulation in the machine and accelerating the flow of humid gas in the machine, thus playing a role in moisture prevention.

[0018] The beneficial effects of the technical solution provided by this invention include: 1. By supporting the LED beads with a round tube and energizing them, the LED beads can emit light. The light is reflected by a conical reflector to illuminate the construction site, achieving the lighting effect. By extending and retracting the electric telescopic pole, a pushing and pulling force can be applied to the electric telescopic pole, which can then rotate and adjust the angle of the conical reflector, thereby increasing the illumination range of the construction site.

[0019] Second, by utilizing the elastic element to continuously apply an elastic force to the round tube, the outer surface of the roller can be tightly fitted with the inner surface of the gradually deforming groove. When the angle of the conical reflector is adjusted, the conical reflector will drive the round tube to rotate and adjust the angle together. Through the gradually deforming groove, a pushing force is applied to the roller, and the round tube will drive the lamp beads to move linearly inside the conical reflector, adjusting the light output focal length and realizing a smooth switch between focused and diffused light spots, meeting the different lighting needs at the engineering site at different distances, increasing the illuminated area, and eliminating obvious dark areas.

[0020] 3. After the LED beads illuminate the construction site, the output of the driver can rotate the support tube clockwise, causing the support tube to tilt the conical reflector towards the bracket. The bracket supports the support tube, which can then be folded, lowering the center of gravity of the lighting equipment and making the equipment easy to move.

[0021] Fourth, the dehumidifier dries the humid air and uses the suction power of the fan, connected by a flexible hose, to draw out the dried air from the dehumidifier. The dried air is then blown out through the bend in the hose into the right-angle bend, and then blown into the nozzle through the horn-shaped limiting cup. The nozzle blows the air out, causing the air inside the machine to be blown out, thus creating air circulation and accelerating the movement of humid air inside the machine, thereby playing a role in preventing moisture.

[0022] 5. With the support tube in a vertical position, the overall center of gravity of the lighting equipment is raised, and the air outlet at the bottom of the right-angle bend is inserted into the inside of the horn-shaped limiting bucket. The bottom end of the right-angle bend applies a pushing force to the right side to the horn-shaped limiting bucket. Under the sliding connection of the I-shaped slider, the brake plate drives the flexible strip to move closer to the wheel. The brake plate presses the flexible strip, making the flexible strip fit against the surface of the wheel, which increases the friction and brakes the wheel, preventing the lighting equipment from moving randomly and making the whole system more stable.

[0023] 6. By using the ball head actuator to apply a counter-thrust to the conical plug, and under the guidance of the guide rod, the conical plug moves away from the air outlet of the right-angle bend, which opens the air outlet of the right-angle bend and sprays gas into the machine body through the jet head.

[0026] Example 1, see Figures 1-5 A technical solution is provided: An outdoor moisture-proof lighting device for building service engineering includes: The body 1 and the bracket 2 fixedly connected to the top side of the body 1. The bottom of the body 1 is equipped with a rolling wheel 3. A right-angled notch 4 is opened on the surface of the body 1 away from the bracket 2. A flexible cover 8 is fixedly connected to the top of the body 1 near the right-angled notch 4. The flexible cover 8 can block rain and prevent rainwater from entering the interior of the body 1. The lighting mechanism 5 includes a support tube 51, a driver 52, and a dehumidifying box 57. The support tube 51 is rotatably installed at the right-angled notch 4 on the top of the body 1. The driver 52 is fixedly installed on the side of the top of the body 1. The dehumidifying box 57 is fixedly installed at the top of the support tube 51. A conical reflector 53 is hinged to the side of the top of the support tube 51 via a U-shaped frame. A transparent cover 54 is installed at the port of the surface of the conical reflector 53. The transparent cover 54 covers the port of the conical reflector 53 to provide protection. An electric telescopic rod 55 is hinged to the surface of the support tube 51 near the conical reflector 53. A light output focal length adjustment component 56 is installed at the top of the support tube 51. A heat-conducting plate 58 is fixedly installed in the middle of the surface of the dehumidifying box 57. The heat-conducting plate 58 dissipates the heat inside the dehumidifying box 57 in a timely manner to achieve a cooling effect. The connecting shaft on the surface of the support tube 51 is fixedly installed with the output end of the driver 52 via a coupling. The telescopic rod of the electric telescopic rod 55 is hinged to the bottom of the conical reflector 53. The electric telescopic rod 55 is a moisture-proof and rainproof telescopic rod.

[0027] The support tube 51 passes through the top of the flexible cover 8, which is made of rubber. The flexible cover 8 is flexible and avoids structural jamming when the support tube 51 is rotated to adjust the angle, so that the support tube 51 can be rotated and adjusted smoothly. The bottom end of the support tube 51 passes through the middle of the right-angled notch 4. The electric telescopic rod 55 is installed at an angle. The heat-conducting plate 58 passes through the dehumidifying box 57 and extends into its interior.

[0028] The light output focus adjustment assembly 56 includes an arc-shaped component 561 and a circular tube 562. The bottom of the arc-shaped component 561 is fixedly installed to the top of the support tube 51. The circular tube 562 is slidably mounted on the end of the conical reflector 53 away from the transparent cover 54. The circular tube 562 can conduct heat out of the conical reflector 53 to cool it down. An LED bead 563 is installed at the end of the circular tube 562 and is installed inside the conical reflector 53. A gradually deformed groove 564 is formed in the middle of the arc-shaped component 561. A roller 565 is rolled on the surface of the circular tube 562 near the inner cavity of the gradually deformed groove 564. An elastic element 566 is fixedly connected between the end face of the conical reflector 53 and the surface of the circular tube 562 near the circular tube 562. The arc-shaped component 561 and the elastic element 565 are... 6. Installed inside the moisture-proof box 57, a flexible sealing plate 567 is fixedly installed between the surface of the conical reflector 53 and the surface of the moisture-proof box 57. The lamp bead 563 is supported by the round tube 562 and powered on, so that the lamp bead 563 can emit light. The light is reflected by the conical reflector 53 to illuminate the construction site, achieving the lighting effect. The electric telescopic rod 55 is activated to work. The extension and retraction of the telescopic end of the electric telescopic rod 55 can apply pushing and pulling forces. Combined with the hinged installation between the conical reflector 53 and the top of the support tube 51, the conical reflector 53 can be rotated to adjust the angle, thereby increasing the illumination range of the construction site. The circular tube 562 passes through the center of the elastic element 566, and the axis of the circular tube 562 coincides with the axis of the conical reflector 53. The outer circular surface of the roller 565 is in contact with the inner surface of the gradually deformed groove 564. By utilizing the elastic element 566 to continuously apply an elastic force to the circular tube 562, the outer circular surface of the roller 565 can be tightly in contact with the inner surface of the gradually deformed groove 564. When the angle of the conical reflector 53 is adjusted, the conical reflector 53 will drive the circular tube 562 to rotate and adjust the angle together. The gradually deformed groove 564 applies a pushing force to the roller 565, and the circular tube 562 will drive the lamp bead 563 to move linearly within the conical reflector 53, thereby adjusting the light output focal length and achieving a smooth switching between focused and diffused light spots. This meets the different lighting needs at the engineering site at varying distances, increases the illuminated area, and eliminates obvious dark areas.

[0029] The round tube 562 passes through the center of the flexible sealing disc 567. The flexible sealing disc 567 is made of rubber. The flexible sealing disc 567 itself is flexible and can block rain, preventing rainwater from entering the interior. At the same time, when the conical reflector 53 rotates to adjust the angle, it avoids structural jamming, making the rotation and adjustment of the conical reflector 53 smooth.

[0030] After the LED 563 illuminates the construction site, the staff turns on the driver 52. By rotating the output of the driver 52, the support tube 51 can be rotated clockwise, causing the support tube 51 to tilt the conical reflector 53 towards the position close to the bracket 2. With the support of the bracket 2, the support tube 51 can be folded, lowering the center of gravity of the lighting equipment and making the equipment easy to move.

[0031] Example 2, based on Example 1, see [link / reference] Figures 1 to 8 A technical solution is provided: A moisture-proof component 6 is installed at the bottom of the surface of the support tube 51. The moisture-proof component 6 includes a suction fan 61, a right-angle elbow 62, and a hose 63. The suction fan 61 is fixedly installed at the bottom of the surface of the support tube 51. The top end of the right-angle elbow 62 is connected to the bottom end of the support tube 51. The hose 63 is installed at the top end of the suction fan 61. A bent pipe 64 is fixedly connected to the surface of the right-angle elbow 62. The top end of the bent pipe 64 is connected to the air outlet of the suction fan 61. The bottom end of the bent pipe 64 passes through the right-angle elbow 62 and extends into the interior of the device. A conical bucket 65 is fixedly connected to the inner wall of the right-angle elbow 62. A guide rod 66 is slidably connected to the surface of the conical bucket 65. A conical plug 67 is fixedly connected to the end of the guide rod 66 away from the conical bucket 65. A dehumidifier 68 is fixedly installed on the side of the surface of the body 1.

[0032] The flexible hose 63 passes through the top of the inner cavity of the flexible cover 8. The flexible hose 63 is curved, and the air inlet end of the flexible hose 63 is connected to the top of the dehumidifier 68.

[0033] The air outlet at the bottom of the bent pipe 64 is connected to the conical hopper 65, and the conical plug 67 is installed at the same height as the conical hopper 65.

[0034] Example 3, based on Examples 1 and 2, see below. Figures 1 to 10 A technical solution is provided: The auxiliary mechanism 7 includes an I-shaped slider 71 and a support rod 72. The I-shaped slider 71 is slidably installed at the bottom of the inner cavity of the machine body 1. The bottom end of the support rod 72 is fixedly installed to the top of the I-shaped slider 71. A plate 73 is fixedly connected to the top of the support rod 72. A jet nozzle 74 is fixedly installed at the middle of the surface of the plate 73. A horn-shaped limiting bucket 75 is installed on the surface of the plate 73 away from the jet nozzle 74. A brake plate 76 is fixedly connected to the bottom of the I-shaped slider 71 near the wheel 3. A flexible strip 77 is fixedly connected to the surface of the brake plate 76. A ball-head actuating member 78 is fixedly connected to the center of the horn-shaped limiting hopper 75. The dehumidifier 68 dries the humid air and uses the suction of the fan. With the connection of the hose, the dried air in the dehumidifier 68 is sucked out and blown into the right-angle bend 62 through the bend pipe 64. The dried gas is then blown into the jet head 74 through the horn-shaped limiting hopper 75. The jet head 74 blows the gas out, causing the air in the machine body 1 to be blown, thereby creating air circulation in the machine body 1 and accelerating the flow of humid gas in the machine body 1, which plays a role in preventing moisture.

[0035] The support rod 72 is installed at an angle. There are two support rods 72, and the two support rods 72 are symmetrically installed along the horn-shaped limiting bucket 75. The horn-shaped limiting bucket 75 is connected to the jet head 74.

[0036] The brake plate 76 is installed at an angle, and flexible strips 77 are evenly distributed on the surface of the brake plate 76. The flexible strips 77 are made of rubber. The heat generated by the LED 563 during illumination heats the air inside the conical reflector 53, causing the air temperature inside the conical reflector 53 to rise. With the connection of the flexible hose 63 and the suction of the suction fan 61, the hot air inside the conical reflector 53 is sucked out and transported through the bent pipe 64, and discharged into the space between the conical hopper 65 and the conical plug 67. The gas pressure is used to apply pressure to the conical plug 67, which can block the air outlet of the right-angle bend 62. This indicates that the support pipe 51 has not been completely reset to a vertical state. 2. The air outlet at the bottom is inserted into the inside of the horn-shaped limiting bucket 75. The bottom end of the right-angle bend 62 will apply a pushing force to the horn-shaped limiting bucket 75. At the same time, when the support tube 51 is in a vertical state, the bottom end of the right-angle bend 62 is completely inserted into the inside of the horn-shaped limiting bucket 75. The ball head actuating member 78 applies a counter-pushing force to the conical plug 67. Under the guidance of the guide rod 66, the conical plug 67 moves away from the air outlet of the right-angle bend 62, so that the air outlet of the right-angle bend 62 can be opened. Hot air enters the jet head 74 from the horn-shaped limiting bucket 75 and is sprayed into the machine body 1 through the jet head 74, promoting the gas flow inside the machine body 1, thereby providing a second moisture protection inside the machine body 1.

[0037] In use, in the initial state, the support tube 51 rests on the bracket 2 and pushes the bracket 2 on the top of the body 1. With the help of the horn-shaped limiting bucket 75, the brake plate 76 will not exert pressure on the flexible strip 77 under the action of no pressure. The flexible strip 77 separates from the wheel 3, so that the wheel 3 rolls smoothly and the body 1 can be moved to the designated location at the construction service project site. When lighting is needed, the operator turns on the driver 52. The rotation output of the driver 52 drives the support tube 51 to rotate counterclockwise, moving the support tube 51 away from the bracket 2. The support tube 51 also drives the right-angle elbow 62 to rotate counterclockwise, making the support tube 51 vertical. The overall center of gravity of the lighting equipment is raised, and the air outlet at the bottom of the right-angle elbow 62 is inserted into the inside of the horn-shaped limiting bucket 75. The bottom end of the right-angle elbow 62 applies a pushing force to the right to the horn-shaped limiting bucket 75. Under the sliding connection of the I-shaped slider 71, the brake plate 76 drives the flexible strip 77 to move closer to the wheel 3. The brake plate 76 presses the flexible strip 77, making the flexible strip 77 fit against the surface of the wheel 3, which increases the friction and brakes the wheel 3, preventing the lighting equipment from moving randomly and making the whole system more stable. Furthermore, by supporting the lamp bead 563 through the round tube 562 and energizing the lamp bead 563, the lamp bead 563 can emit light. The light is reflected by the conical reflector 53 to illuminate the construction site, achieving the lighting effect. The electric telescopic pole 55 is then activated. By extending and retracting the telescopic end of the electric telescopic pole 55, pushing and pulling forces can be applied to the electric telescopic pole 55. Combined with the hinged installation between the conical reflector 53 and the top of the support tube 51, the conical reflector 53 can be rotated to adjust its angle, thereby increasing the illumination range of the construction site. Meanwhile, by utilizing the elastic element 566 to continuously apply an elastic force to the circular tube 562, the outer circular surface of the roller 565 can be tightly fitted with the inner surface of the gradually deformed groove 564. When the conical reflector 53 is adjusted in angle, the conical reflector 53 will drive the circular tube 562 to rotate and adjust the angle together. By applying a pushing force to the roller 565 through the gradually deformed groove 564, the circular tube 562 will drive the lamp bead 563 to move linearly within the conical reflector 53, thereby adjusting the light output focal length and achieving a smooth switching between focused and diffused light spots. This meets the different lighting needs at the engineering site at varying distances and increases the illuminated area. Furthermore, by using the ball-head actuating component to apply a counter-thrust to the conical plug, and under the guidance of the guide rod, the conical plug moves away from the air outlet of the right-angle bend, thus allowing the air outlet of the right-angle bend to open. Furthermore, the dehumidifier 68 dries the humid air and uses the suction of the fan, connected by a hose, to draw out the dried air from the dehumidifier 68 and blow it out through the bend pipe 64 into the right-angle bend 62. The dried air is then blown into the jet nozzle 74 through the horn-shaped limiting bucket 75. The jet nozzle 74 blows the air out, causing the air inside the unit 1 to be blown out, thereby creating air circulation inside the unit 1 and accelerating the flow of humid air inside the unit 1, thus playing a role in preventing moisture. After the LED 563 illuminates the construction site, the staff turns on the driver 52. The rotation of the output end of the driver 52 can drive the support tube 51 to rotate clockwise, causing the support tube 51 to tilt the conical reflector 53 towards the position close to the bracket 2. With the support of the bracket 2, the support tube 51 can be folded, lowering the center of gravity of the lighting equipment. The support tube 51 also drives the right-angle elbow 62 to rotate in the opposite direction, and the pushing force of the right-angle elbow 62 on the horn-shaped limiting bucket 75 disappears. The flexible strip 77 separates from the wheel 3, releasing the brake on the wheel 3, making the equipment easy to move.

[0038] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. The scope of protection of the present invention should be determined by the scope of the claims.
