Description

Technical Field

[0001] This utility model belongs to the field of building construction lighting technology, and specifically relates to a lighting device used in building construction. Background Technology

[0002] Construction sites often face challenges such as insufficient ambient light and complex work surfaces, necessitating adequate illumination to ensure worker safety and improve work efficiency. Construction site lighting systems must not only adapt to daytime and nighttime variations but also consider adverse weather conditions and uneven terrain. Therefore, lighting equipment used in construction projects requires high brightness, adjustability, durability, and resistance to weathering.

[0003] Patent publication number CN212456556U discloses a lighting device for building construction, including a mounting frame with mounting legs snapped onto both ends. A movable device is fixedly mounted on the bottom of each mounting leg. A telescopic rod extending to the outside of the mounting frame is fixedly mounted inside the frame, and an adjustable lamp is fixedly mounted on the top of the telescopic rod. This patent, by incorporating an adjustable lamp, allows the lighting device to be adjusted at various angles during use, thus avoiding obstruction from obstacles and improving its practicality. By placing the telescopic rod inside the mounting frame, it can be retracted into the frame, and the mounting legs can be retracted to the sides of the frame, reducing the footprint of the lighting device and facilitating storage.

[0004] However, current lighting devices used in building construction have the following problems: existing lighting devices do not have the ability to diffuse and converge light, making it impossible for the device to adjust the light illumination range and intensity according to the working environment. Therefore, we propose a lighting device for building construction. Utility Model Content

[0005] The purpose of this invention is to provide a lighting device for building construction that solves the problem that existing lighting devices in the related technology do not have the ability to diffuse and converge light, making it impossible for the device to adjust the range and intensity of light illumination according to the working environment.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A lighting device for building construction includes a support plate, a fixed base fixedly connected to the bottom of the support plate, a light-emitting component for emitting lighting light disposed on the top of the support plate, a protective cover fixedly connected to the top of the support plate, a light source focusing device disposed at the bottom of the support plate, the light source focusing device including a motor bracket, the top of the motor bracket fixedly connected to the bottom of the support plate, a driving component disposed at the bottom of the motor bracket, a focusing prism fixedly connected to the driving end of the driving component, a vertical slider fixedly connected to the outer wall of the focusing prism, and a sliding column fixedly connected to the top of the support plate.

[0008] The drive assembly includes a drive motor, the top of which is fixedly connected to the bottom of a motor bracket. The output shaft of the drive motor is fixedly connected to an extension shaft, and the top of the extension shaft is fixedly connected to a threaded rod. A threaded slider is threadedly connected to the threaded surface of the threaded rod. The outer wall of the convergent prism is fixedly connected to the side of the threaded slider, and the threaded slider is the drive end of the drive assembly.

[0009] The light-emitting component for emitting illumination light includes a stable base, the bottom of which is fixedly connected to the top of a support plate, and an incandescent lamp body is fixedly connected to the top of the stable base. A light / dark controller is provided on the top of the incandescent lamp body.

[0010] The inner diameter of the slot of the vertical slider is equal to the outer diameter of the sliding column, and the inner wall of the slot of the vertical slider is in contact with the outer wall of the sliding column.

[0011] The convergence prism is a concave lens, and a gap is provided between the bottom of the convergence prism and the light-emitting component.

[0012] An anti-obstruction device is provided on the outer wall of the extension shaft. The anti-obstruction device includes a friction wheel. The inner wall of the friction wheel is fixedly connected to the outer wall of the extension shaft. A friction ring is rotatably connected to the bottom of the support plate. A shaped extension rod is fixedly connected to the outer wall of the friction ring. A scraping rod is fixedly connected to the top of the shaped extension rod. An outer ring is fixedly connected to the outer wall of the scraping rod.

[0013] The outer wall of the friction wheel is in contact with the inner wall of the friction ring, and the inner wall of the scraping rod is in contact with the outer wall of the protective cover.

[0014] The technical effects achieved by this utility model are as follows:

[0015] This utility model, through the setting of a light source focusing and diffusing device, enables the motor bracket, drive motor, extension shaft, threaded rod, threaded slider, focusing prism, vertical slider, and sliding column to rotate, thereby driving the threaded slider to move. The threaded slider's movement causes the focusing prism to move downward or upward under the constraint of the vertical slider and sliding column, thus achieving the convergence and diffusion of the light illumination range, making the lighting device better adaptable to the working environment.

[0016] This invention, through the setting of an anti-obstruction device, enables the friction wheel, friction ring, irregularly shaped extension rod, scraping rod, outer ring, and extension shaft to rotate, thereby driving the friction wheel to rotate. The rotation of the friction wheel causes the friction ring to rotate under its frictional force, which in turn drives the irregularly shaped extension rod to rotate. The rotation of the irregularly shaped extension rod then drives the scraping rod to rotate, allowing the scraping rod to clean the dust and dirt adhering to the surface of the protective cover, thus preventing dust and adhering substances from blocking light and causing poor lighting effects.

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figure 1-5 As shown, a lighting device for building construction includes a support plate 1, a fixed base 2 fixedly connected to the bottom of the support plate 1, a light-emitting component 3 for emitting lighting light on the top of the support plate 1, a protective cover 4 fixedly connected to the top of the support plate 1, and a light source focusing device 5 at the bottom of the support plate 1. The light source focusing device 5 includes a motor bracket 51, the top of which is fixedly connected to the bottom of the support plate 1. A driving component is provided at the bottom of the motor bracket 51, and a focusing prism 56 is fixedly connected to the driving end of the driving component. A vertical slider 57 is fixedly connected to the outer wall of the focusing prism 56, and a sliding column 58 is fixedly connected to the top of the support plate 1. The sliding column 58 can ensure the stable operation of the focusing prism 56.

[0026] The drive assembly includes a drive motor 52, which is electrically connected to an external controller. The top of the drive motor 52 is fixedly connected to the bottom of the motor bracket 51. The output shaft of the drive motor 52 is fixedly connected to an extension shaft 53. A threaded rod 54 is fixedly connected to the top of the extension shaft 53. A threaded slider 55 is threadedly connected to the threaded surface of the threaded rod 54. The outer wall of the convergence prism 56 is fixedly connected to the side of the threaded slider 55. The threaded slider 55 is the drive end of the drive assembly. The drive assembly can ensure the smooth operation of the entire device.

[0027] The light-emitting component 3 for emitting illumination light includes a stable base 31. The bottom of the stable base 31 is fixedly connected to the top of the support plate 1. An incandescent lamp body 32 is fixedly connected to the top of the stable base 31. A light and dark controller 33 is provided on the top of the incandescent lamp body 32. This is prior art and will not be described in detail.

[0028] The inner diameter of the slot of the vertical slider 57 is equal to the outer diameter of the slide column 58, and the inner wall of the slot of the vertical slider 57 is in contact with the outer wall of the slide column 58. The necessary contact ensures the stable operation of the device.

[0029] The convergence prism 56 is a concave lens, and there is a gap between the bottom of the convergence prism 56 and the light-emitting component 3. The concave lens has the ability to scatter light.

[0030] According to the above structure, when the staff feels that the light is too dim while working, the staff can turn on the light and dark controller 33 through the external controller to adjust the light intensity. Then, the staff can turn on the drive motor 52 through the external controller. The output shaft of the drive motor 52 rotates, which drives the extension shaft 53 to rotate. The rotation of the extension shaft 53 drives the threaded rod 54 to rotate. The rotation of the threaded rod 54 drives the threaded slider 55 to move. The threaded movement of the threaded slider 55 causes the convergence prism 56 to move downward or upward under the restriction of the vertical slider 57 and the sliding column 58, thereby realizing the convergence and diffusion of the light illumination range, so that the lighting device can better adapt to the working environment.

[0031] like Figure 1-5 As shown, an anti-blocking device 6 is provided on the outer wall of the extension shaft 53. The anti-blocking device 6 includes a friction wheel 61.

A shaped extension rod 63 is fixedly connected to the outer wall of the friction ring 62. A scraping rod 64 is fixedly connected to the top of the shaped extension rod 63. An outer ring 65 is fixedly connected to the outer wall of the scraping rod 64. The outer ring 65 can protect the device from damage.

[0032] The outer wall of the friction wheel 61 contacts the inner wall of the friction ring 62, and the inner wall of the scraping rod 64 contacts the outer wall of the protective cover 4. The necessary contact ensures the stable operation of the device.

[0033] According to the above structure, the rotation of the extension shaft 53 drives the friction wheel 61 to rotate. The rotation of the friction wheel 61 causes the friction ring 62 to rotate under its frictional force. The rotation of the friction ring 62 drives the irregular extension rod 63 to rotate. The rotation of the irregular extension rod 63 drives the scraping rod 64 to rotate, so that the scraping rod 64 cleans the dust and dirt attached to the surface of the protective cover 4, so as to avoid the dust and attachments blocking the light and causing poor lighting effect.
