Description

An LED light with a height-adjustable light source Technical Field

[0001] This utility model relates to the field of lighting, and more particularly to an LED lamp with a height-adjustable light source. Background Technology

[0002] A lamp refers to a lighting device. Lamps come in a wide variety of types and have diverse uses. For example, ceiling lights are suitable for living rooms, bedrooms, and other indoor spaces, while table lamps are ideal for studying or working. Furthermore, lamps are made from a variety of materials, including glass, crystal, and metal.

[0003] With the development of society, outdoor lights are installed for the safety of people and property. In order to illuminate a wider range, outdoor lights are generally installed at a relatively high height, more than two meters. When outdoor lights malfunction, tools are needed to fix them. This not only requires waiting for staff to come with the tools, but also makes it easy for staff to have accidents while sitting on the supports.

[0004] Therefore, it is necessary to design an LED light with a height-adjustable light source to solve the above problems. Summary of the Invention

[0005] To overcome the disadvantage that outdoor lights are generally installed higher than a person and require tools for maintenance or replacement, this utility model provides an LED light with a height-adjustable light source.

[0006] The technical solution of this utility model is: an LED light with a liftable light source, including a support rod, a protective shell, a winding wheel, a fixing component, a pull rope, an outdoor light body, a spiral spring, and a manual crank. The top of the support rod is provided with a protective shell. A winding wheel is rotatably arranged inside the support rod, and a pull rope is wound inside the winding wheel. Several fixing components are installed inside the support rod, and the pull rope slides through the fixing components. The outdoor light body is slidably arranged on the outside of the support rod. The pull rope is connected to the outdoor light body from the top of the support rod. A spiral spring is installed on the side of the winding wheel, and a manual crank is installed on the side of the spiral spring away from the winding wheel.

[0007] As a preferred technical solution of this utility model, it also includes a drive motor, a worm and a worm wheel. The drive motor is installed on the side of the support rod, and the output shaft of the drive motor is connected to the worm through a coupling. The end of the winding wheel away from the spiral spring is equipped with a worm wheel, and the worm wheel meshes with the worm.

[0008] As a preferred technical solution of this utility model, it also includes a support plate and a contact button. The support plate is symmetrically installed on the top of the support rod, and the contact button is installed on the bottom of each support plate. The contact button is in contact with the top of the outdoor light body.

[0009] As a preferred embodiment of this utility model, it also includes an indicator light, which is installed on the side of the support rod and is electrically connected to the contact button.

[0010] As a preferred embodiment of this utility model, it also includes a solar panel, with the solar panel installed on the top of the protective shell.

[0011] As a preferred technical solution of this utility model, it also includes a reflector, and the reflector is attached to the side of the support rod.

[0012] This utility model has the following advantages: When it is necessary to move the outdoor lamp body downward from the top, the manual crank is turned, which drives the spiral spring to rotate, and the spiral spring drives the winding wheel to rotate. The pull rope on the winding wheel is loosened, and the outdoor lamp body moves downward along the support rod under its own gravity. When it is necessary to move upward, the manual crank is turned in the opposite direction to achieve the effect of raising and lowering. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] An LED light with a height-adjustable light source, as shown in Figures 1-5, includes a support rod 1, a protective shell 2, a winding wheel 4, a fixing member 5, a pull rope 6, an outdoor light body 7, a spiral spring 8, and a manual crank 3. The protective shell 2 is provided on the top of the support rod 1. The winding wheel 4 is rotatably arranged inside the bottom of the support rod 1, and the pull rope 6 is wound inside the winding wheel 4. Several fixing members 5 are installed inside the support rod 1, and the pull rope 6 slides through the fixing members 5. The fixing members 5 are arranged in two rows to restrict the pull rope 6. The outdoor light body 7 is slidably arranged on the outside of the support rod 1. The pull rope 6 passes through the top of the support rod 1 and is connected to the top surface of the outdoor light body 7. The spiral spring 8 is installed on the side of the winding wheel 4, and the manual crank 3 is installed on the side of the spiral spring 8 away from the winding wheel 4.

[0021] As shown in Figure 5, it also includes a drive motor 9, a worm gear 10 and a worm wheel 11. The drive motor 9 is installed on the side of the support rod 1. The output shaft of the drive motor 9 is connected to the worm gear 10 through a coupling. The worm wheel 11 is installed on the left end of the winding wheel 4. The worm wheel 11 and the worm gear 10 mesh with each other, which is the function of the electric lifting outdoor light body 7.

[0022] When it is necessary to move the outdoor light body 7 from the top of the support rod 1, the drive motor 9 works, driving the worm gear 10 to rotate. The worm gear 10 drives the meshing worm wheel 11 to rotate, and the worm wheel 11 drives the winding wheel 4 to rotate. As a result, the pull rope 6 on the winding wheel 4 is loosened, and the outdoor light body 7 moves downward along the support rod 1 under its own gravity until it reaches the designated position. Alternatively, the outdoor light body 7 can be lowered by shaking the manual crank 3, which drives the spiral spring 8 to rotate. The spiral spring 8 drives the winding wheel 4 to rotate, which loosens the pull rope 6.

[0023] As shown in Figure 3, it also includes a support plate 12, a contact button 13, and an indicator light 14. The support plate 12 is symmetrically installed on the top of the support rod 1, and a contact button 13 is installed on the bottom of each support plate 12. The contact button 13 contacts the top of the outdoor light body 7. The indicator light 14 is installed on the side of the support rod 1. The indicator light 14 is electrically connected to the contact button 13 and plays the role of controlling the switch of the indicator light 14.

[0024] When the outdoor light body 7 rises to the top of the support rod 1, the top of the outdoor light body 7 touches the contact button 13, the contact button 13 is activated, the circuit of the indicator light 14 is connected, the indicator light 14 lights up, indicating to the staff that the outdoor light body 7 has risen to the top.

[0025] As shown in Figure 1, it also includes a solar panel 15, which is installed on the top of the protective shell 2.

[0026] The solar panel 15 installed on the top of the protective shell 2 serves to absorb solar energy.

[0027] As shown in Figure 1, it also includes a reflector 16, and the reflector 16 is attached to the side of the support rod 1.

[0028] The reflector 16 attached to the side of the support rod 1 serves to alert people in the surrounding area to pay attention to safety.

[0029] It should be understood that this embodiment is for illustrative purposes only and is not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
