Description

Technical Field

[0001] This utility model relates to the field of lighting equipment technology, and in particular to a lighting device. Background Technology

[0002] Lighting tools are essential for daily work and study. Among them, desk lamps are widely used in homes, offices, and various study spaces due to their flexibility and portability. Most desk lamps on the market are desktop-mounted, supported by a base on a desktop or other flat surface. They are powered by AC power via a power cord to meet the lighting needs of a localized area. These desk lamps have a relatively simple structure and can basically achieve basic lighting functions.

[0003] Existing desktop lamps occupy desktop space, reducing usable area, which can be inconvenient, especially when there are many items on the desk. Furthermore, the fixed power cord length of these lamps often limits their movement, and problems such as cord tangling and plug detachment can occur during dragging. Therefore, a new lighting device is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that existing desktop lamps occupy a certain amount of desktop space, reducing the usable area of ​​the desktop, which is especially inconvenient when there are many items on the desktop. Therefore, this utility model proposes a lighting device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A lighting device includes a guide rail with an opening facing downwards and a slider slidably connected inside. The bottom of the slider extends out of the opening below the guide rail and is fixedly connected to a hollow lamp post. A lighting lamp is fixedly installed at one end of the lamp post by bolts.

[0007] A wire is fixed to one side of the slider. One end of the wire passes through the slider and the lamp post and is electrically connected to the lighting lamp. A cavity for guiding the wire is provided in the guide rail. A baffle is integrally formed on one side of the cavity. A gap is provided between the top of the baffle and the top inner wall of the guide rail for the wire to move. The end of the wire away from the lighting lamp passes through the guide rail.

[0008] A positioning mechanism is provided at the bottom of the slider for positioning the slider.

[0009] As a further embodiment of this utility model, a back plate is fixed to the side of the guide rail away from the lighting lamp by bolts, and the length of the back plate is greater than that of the guide rail.

[0010] As a further improvement of this utility model, both ends of the back plate are provided with through fixing holes.

[0011] As a further embodiment of this utility model, the positioning mechanism includes a base plate and a slide rod. The base plate is fixed to the bottom of the guide rail, and the slide rod slides through one side of the slider. The base plate has a plurality of evenly distributed slots on the side near the slide rod. A retaining plate is fixedly connected to the end of the slide rod near the slot, and the retaining plate is inserted into one of the slots. A spring is installed between the slide rod and the slider through a spring seat, and the spring is sleeved on the circumference of the slide rod.

[0012] As a further improvement of this utility model, a handle is fixedly connected to the end of the slide rod away from the card plate.

[0013] As a further embodiment of this utility model, one end of the wire extends out of the guide rail and is electrically connected to the controller, and the other end of the controller is electrically connected to the power cord with a plug.

[0014] Working principle: In this application, the product can be fixed to a wall or other fixed surface via the back plate. Fixing can be done using bolts or adhesive, and the fixing height is determined according to usage requirements. The product is fixed via a power cord connected to a socket, and the lighting is controlled by a controller. The wall-mounted installation reduces desktop space occupation. When the lighting position needs to be moved, pull the slider to disengage the card plate from the slot, and then move the slider. The wire moves within the cavity and is restricted by a baffle to prevent it from detaching from the cavity. This makes it more convenient to use when working or performing tasks in other locations on the desktop, and avoids the problem of insufficient wire length and instability when dragging a traditional desk lamp on the desktop.

[0015] Beneficial effects: In this utility model, the lighting device, through the combined use of a back plate, fixing holes, and guide rails, replaces the traditional desktop placement with wall mounting. The fixing holes are compatible with expansion bolts or adhesives to meet the needs of different installation scenarios. The longer back plate makes the fixing points more dispersed, improving installation stability, completely reducing desktop space occupation, and avoiding the problems of traditional table lamps taking up space and being easy to tip over.

[0016] In this invention, the lighting device utilizes a positioning mechanism in conjunction with a cavity and a baffle. Pulling the sliding rod releases the positioning, and moving the slider causes the spring to automatically reset and fix the device, allowing for flexible adjustment of the lighting. The wire moves orderly within the cavity, and the baffle prevents it from detaching, avoiding the problems of insufficient wire length and tangling / wear during dragging common in traditional table lamps.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] In one embodiment: Refer to Figures 1-3 A lighting device includes: a guide rail 1, which may be made of aluminum alloy and is elongated with its opening facing downwards. The guide rail 1 has an internal sliding chamber that matches a slider 8. The slider 8 is made of engineering plastic and can slide smoothly along the length of the guide rail 1. An extension is integrally formed at the bottom of the slider 8, which passes through the opening below the guide rail 1 and extends to the outside of the guide rail 1. A lamp post 6 is bolted to the bottom of the extension. The lamp post 6 is a hollow tubular structure. A light bulb 7 is fixed to the end of the lamp post 6 away from the slider 8. The light bulb 7 can move along the length of the guide rail 1, making it more convenient to use when working or performing tasks at other locations on the desktop. This also avoids the problem of traditional desk lamps being dragged across the desktop due to insufficient cord length and instability.

[0023] A wire clip for the wire 11 is fixed to one side of the outer wall of the slider 8 by screws. One end of the wire 11 passes through a pre-set wire hole inside the slider 8, through the hollow cavity of the lamp post 6, and finally connects electrically to the terminal of the lighting lamp 7. To prevent the wire 11 from getting tangled or worn when the slider 8 moves, a cavity 9 is specially provided inside the guide rail 1 to guide the wire 11. This cavity 9 is independent of the sliding cavity of the slider 8. A baffle 10 is integrally formed on the side of the cavity 9 near the sliding cavity of the slider 8. The baffle 10 extends along the length of the guide rail 1, and a gap is reserved between its top and the top inner wall of the guide rail 1. The gap allows the wire 11 to pass through and move with the slider 8. The baffle 10 can restrict the wire 11 inside the cavity 9, effectively preventing the wire 11 from deviating from the preset path and rubbing against the slider 8. The end of the wire 11 away from the lighting lamp 7 is led out from the cavity 9 and extends through a pre-set wire outlet hole at the end of the guide rail 1 to the outside of the guide rail 1.

[0024] A back plate 2 is bolted to the side of the guide rail 1 away from the light 7. The back plate 2 is longer than the guide rail 1. Both ends of the back plate 2 are machined with through fixing holes 3. In actual installation, expansion bolts can be used to pass through the fixing holes 3 to fix the back plate 2 to the wall or other fixed surface. If the installation surface is not suitable for drilling, adhesive can also be used to directly glue and fix the back plate 2. The specific fixing height can be adjusted according to the user's needs. The wall-mounted installation method can completely reduce the occupation of desktop space.

[0025] A positioning mechanism for positioning the slider 8 is located at the bottom of the slider 8. This mechanism includes a base plate 12 and a slide rod 14. The base plate 12 is fixed to the bottom outer wall of the guide rail 1 by bolts, and its length is the same as that of the guide rail 1. The slide rod 14 slides through a pre-set guide hole on one side of the slider 8. The inner wall of the guide hole is polished to reduce the resistance when the slide rod 14 slides. Multiple evenly distributed slots 13 are machined along the length direction on the side of the base plate 12 near the slide rod 14. A retaining plate 15 is fixed to the end of the slide rod 14 near the slot 13 by a threaded connection. The shape of the retaining plate 15 matches the slot 13 and can be inserted into the slot 13 to achieve snap-fit ​​positioning. A spring 16 is fitted on the part of the slide rod 14 between the slider 8 and the retaining plate 15. The two ends of the spring 16 are fixedly connected to the outer wall of the slider 8 and the side of the retaining plate 15 by spring seats, respectively. To facilitate operation of the slide bar 14, a handle is fixedly connected to the end of the slide bar 14 away from the locking plate 15 via a nut. The handle is made of plastic with anti-slip texture on its surface. When the position of the lighting lamp 7 needs to be moved, the handle is gripped and the slide bar 14 is pulled outward. The slide bar 14 causes the locking plate 15 to disengage from the slot 13. At the same time, the spring 16 is compressed, generating elastic potential energy. This pushes the slider 8 to move along the length of the guide rail 1. During the movement of the slider 8, the lamp post 6 and the lighting lamp 7 move synchronously. During this process, the wire 11 moves inside the cavity 9 with the movement of the slider 8. The baffle 10 can limit the movement of the wire 11, preventing it from disengaging from the cavity 9. After the lighting lamp 7 is moved to the desired position, the handle is released. The spring 16 releases its elastic potential energy, pushing the locking plate 15 back into the corresponding slot 13, completing the positioning of the slider 8 and ensuring that the lighting lamp 7 is stable in the target position.

[0026] In another embodiment: Reference Figures 1-3 A lighting device, the structure of which is basically the same as the previous embodiments, the difference being:

[0027] One end of the wire 11 extending from the outside of the guide rail 1 is electrically connected to the controller 5. The controller 5 adopts a conventional lighting control module, and its surface is equipped with a start / stop button and a brightness adjustment knob. The other end of the controller 5 is electrically connected to the power cord 4 with a plug. In actual use, the plug of the power cord 4 can be inserted into the mains socket to power the entire device. The buttons and knobs on the controller 5 can be used to conveniently control the lighting lamp 7 to turn on, off, and adjust its brightness. When the user works or does tasks at different positions on the desktop, they only need to adjust the position of the lighting lamp 7 in the above manner to obtain a suitable lighting effect, avoiding the problems of insufficient wire length and poor stability caused by dragging the traditional desk lamp on the desktop.

[0028] However, as is well known to those skilled in the art, the working principles and wiring methods of the power cord 4, controller 5 and lighting lamp 7 are commonplace and are all conventional methods or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0029] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
