Description

Technical Field

[0001] This utility model relates to a hanging lamp, belonging to the technical field of lighting fixtures. Background Technology

[0002] Hanging lights are lamps suspended in the air, serving functions such as signage, illumination, and decoration. Currently, most hanging lights use LED strips connected to the light box via nuts on a hanging rod. This results in uneven light transmission, with the light passing through the light box being either too dim or too bright, due to the influence of the connecting nuts. To improve light uniformity, more flexible LED strips are typically added inside the light box, leading to excessively high power consumption.

[0003] To address this issue, Chinese utility model patent application CN201820767787.8 discloses a U-shaped hanging light box with uniform light transmission. Through the arrangement of a light guide plate, it enhances the overall light transmission uniformity of the light box body while reducing the power consumption of the light box body, thus achieving good energy-saving effects and effectively solving the aforementioned problems in the prior art. However, during installation, it requires a hanging rod to connect the light guide plate, and holes need to be drilled in the light guide plate to insert corresponding metal connectors to connect it to the light strips. This leads to the following problems in actual use:

[0004] 1. This type of suspension method requires an additional hanging structure, which may compress the floor height, making it more susceptible to collisions with external objects.

[0005] 2. The way the hanging rod is connected is prone to shaking. Over time, the entire light fixture may fall off due to gravity shifting or loosening.

[0006] 3. Drilling holes in the light guide plate is necessary. Due to the material limitations of the light guide plate, the failure rate of drilling is high, and the drilling method can also damage the overall structure of the light guide plate.

[0007] 4. The L-shaped corner brackets are not convenient for connecting and replacing the light strips to the light guide plate. Utility Model Content

[0008] In order to solve the above-mentioned problems existing in the prior art, this utility model provides a hanging lamp.

[0009] The technical solution of this utility model is as follows:

[0010] A hanging light includes a base for connecting to a mounting surface. From top to bottom, a connecting profile, an LED light strip, and a light guide plate are sequentially arranged below the base. The base and the connecting profile are connected together by a slider-slide groove structure. The LED light strip and the light guide plate are both connected to the connecting profile by a slot structure.

[0011] The slider-groove structure includes a slider part arranged in an inverted T-shape and fixedly installed on the bottom surface of the base along the length direction of the base, and a groove part opened on the top surface of the connecting profile and arranged in a manner that is adapted to the shape and distribution of the slider part. The slider part is slidably connected to the groove part to connect the base and the connecting profile together.

[0012] The slot structure includes a first slot and a second slot arranged along the length of the connecting profile and opened on the bottom surface of the connecting profile. The first slot is located above the second slot and the first slot and the second slot are connected. The shape of the first slot is adapted to the shape of the LED light strip, and the shape of the second slot is adapted to the shape of the light guide plate. The LED light strip is inserted into the first slot and the light guide plate is inserted into the second slot to achieve connection with the connecting profile.

[0013] The connecting profile and the light guide plate are further limited by a limiting structure. The limiting structure includes a first limiting strip symmetrically arranged on the top of the light guide plate, a limiting groove formed on both sides of the second slot and adapted to the corresponding first limiting strip, and a second limiting strip symmetrically arranged on the bottom of the connecting profile. The limiting grooves on both sides are connected to the second slot. When the light guide plate is inserted into the second slot, the first limiting strips on both sides enter the corresponding limiting grooves on both sides. A limiting opening is left between the second limiting strips on both sides, allowing the light guide plate to pass through but not allowing the first limiting strips on both sides to pass through.

[0014] The connecting profile has sealing grooves at both ends. The sealing grooves on both sides are connected to the corresponding side ends of the sliding groove, the first slot, the second slot and the limiting groove. Sealing plates are inserted into the sealing grooves on both sides. The sealing plates on both sides cover the corresponding side sealing grooves to seal the corresponding side ends of the sliding groove, the first slot, the second slot and the limiting groove.

[0015] The first slot is also provided with a wire passage hole that connects the first slot to the top surface of the connecting profile.

[0016] The base is provided with a cable routing groove on its bottom surface. When the base is connected to the connecting profile, the cable hole and the cable routing groove are connected.

[0017] The base is connected to the mounting surface by connecting screws.

[0018] This utility model has the following beneficial effects:

[0019] This invention replaces the traditional hanging rod structure with a slider-slide groove structure. Eliminating the hanging rod structure reduces the overall height of the hanging light, thus minimizing its impact on the ceiling height and making it less prone to collisions with external objects. The slider-slide groove structure also improves the overall stability of the hanging light, preventing it from easily wobbling and thus reducing the likelihood of it falling off. Furthermore, by using a slot structure instead of traditional corner bracket connectors, the slot structure eliminates the need for openings in the light guide plate, ensuring the integrity of the overall structure, better light guiding effect, longer service life, and avoiding the costs associated with openings in the light guide plate. The LED light strip can also be directly pulled out from the side of the hanging light through the first slot for easy replacement. Compared to existing technologies, this invention offers advantages such as reduced risk of collisions with external objects, overall structural stability, intact light guide plate structure, and convenient light strip replacement.

[0025] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0026] Example: Please refer to Figures 1-3 This embodiment provides a hanging lamp, including a base 1 for connecting to a mounting surface. The base 1 is fixedly connected to the mounting surface by driving in connecting screws 17, or other fixed connection methods can be used to connect to the mounting surface.

[0027] Below the base 1, from top to bottom, are arranged a connecting profile 2, an LED light strip 3, and a light guide plate 4. The base 1 and the connecting profile 2 are connected together by a slider and groove structure. The LED light strip 3 and the light guide plate 4 are both connected to the connecting profile 2 by a slot structure.

[0028] In this embodiment, the slider-slide structure includes two slider sections 5 arranged along the length of the base 1. The slider sections 5 are inverted T-shaped and are fixedly mounted symmetrically on the bottom surface of the base 1. A slide groove 6, corresponding to the shape of the slider sections 5, is provided on the top surface of the connecting profile 2. Both ends of the slide groove 6 penetrate the corresponding side face of the connecting profile 2 for subsequent insertion of the slider sections 5. The two slider sections 5 slide into the corresponding slide groove 6 from one side. By utilizing the cooperation between their horizontal segment structure and the horizontal groove of the corresponding slide groove 6, they can only slide left and right along the corresponding slide groove 6 and cannot move up and down, thus connecting the base 1 and the connecting profile 2 together.

[0029] In this embodiment, the slot structure includes a first slot 7 and a second slot 8 arranged along the length of the connecting profile 2 and formed on the bottom surface of the connecting profile 2. The first slot 7 is positioned above the second slot 8 and is connected to the second slot 8. Both ends of the first slot 7 and the second slot 8 penetrate the corresponding side end faces of the connecting profile 2. The shape of the first slot 7 is adapted to the shape of the LED light strip 3, and the shape of the second slot 8 is adapted to the shape of the light guide plate 4. The LED light strip 3 is connected to the connecting profile 2 by being inserted into the first slot 7, and the light guide plate 4 is connected to the connecting profile 2 by being inserted into the second slot 8. At the same time, the bottom of the light guide plate 4 extends downward from the second slot 8 to provide the required light guiding function.

[0030] To strengthen the connection between the LED light strip 3 and the light guide plate 4 and the connecting profile 2, in this embodiment, a limiting structure is also provided between the connecting profile 2 and the light guide plate 4 for limiting. The limiting structure includes a first limiting strip 9 symmetrically arranged on the top of the light guide plate 4, a limiting groove 10 formed on both sides of the second slot 8 and adapted to the corresponding first limiting strip 9, and a second limiting strip 11 symmetrically arranged on the bottom of the connecting profile 2. The first limiting strips 9 on both sides are fixedly connected to the light guide plate 4, and can be fixedly connected to the light guide plate 4 by means of adhesive bonding or other fixed connection methods that do not damage the structure of the light guide plate 4. The limiting grooves 10 on both sides are connected to the second slot 8. When the light guide plate 4 is inserted into the second slot 8, the first limiting strips 9 on both sides enter the corresponding limiting groove 10. A limiting opening 12 is left between the second limiting strips 11 on both sides, allowing the light guide plate 4 to pass through but not allowing the first limiting strips 9 on both sides to pass through. The bottom of the light guide plate 4 extends outward from the limiting opening 12 to ensure its light guiding function. During installation, the first limiting strips 9 on both sides are connected to the light guide plate 4 from the side of the connecting profile 2. The light guide plate 4 is inserted into the second slot 8, and its bottom passes through the limiting port 12. The first limiting strips 9 on both sides are inserted into the limiting slots 10 on both sides, and are limited by the second limiting strips 11 on both sides and cannot pass through the limiting port 12. This makes the light guide plate 4 only able to move left and right but not up and down. In other words, the light guide plate 4 can be connected to the connecting profile 2 well. The LED light strip 3 is located between the light guide plate 4 and the connecting profile 2. It can only move left and right due to its limitation, and can also be installed well on the connecting profile 2.

[0031] To further ensure the connection effect between the base 1, LED light strip 3, and light guide plate 4 and the connecting profile 2, in this embodiment, sealing grooves 13 are provided on both ends of the connecting profile 2. The sealing grooves 13 on both sides are connected to the corresponding side ends of the sliding groove 6, the first slot 7, the second slot 8, and the limiting groove 10. Sealing plates 14 are inserted into the sealing grooves 13 on both sides, and the sealing plates 14 cover the corresponding side sealing grooves 13 to close the corresponding side ends of the sliding groove 6, the first slot 7, the second slot 8, and the limiting groove 10. By providing the aforementioned sealing grooves 13 and sealing plates 14, and closing the corresponding side ends of the sliding groove 6, the first slot 7, the second slot 8, and the limiting groove 10, the left and right movement of the slider 5, LED light strip 3, and light guide plate 4 can be restricted. Combined with their restricted up and down movement, this effectively ensures the connection effect between the base 1, LED light strip 3, and light guide plate 4 and the connecting profile 2, making them less prone to detachment.

[0032] To facilitate the subsequent wiring of the LED light strip 3, in this embodiment, the first slot 7 is also provided with a wire-passing hole 15 that connects the first slot 7 to the top surface of the connecting profile 2. A wiring groove 16 is also provided on the bottom surface of the base 1. When the base 1 is connected to the connecting profile 2, the wire-passing hole 15 and the wiring groove 16 are connected. Through the wire-passing hole 15 and the wiring groove 16, the power lines of the LED light strip 3 can be led out to the outside of this hanging light through the wire-passing hole 15 and the wiring groove 16, thereby connecting to the required power supply.

[0033] In practical use, the dot parameters of the light guide plate 4 can be optimized to improve its overall uniformity and appearance, resulting in a better and more aesthetically pleasing lighting effect for this hanging light. Specific optimization methods include:

[0034] On the light guide plate 4, in the area close to the LED strip 3, the dot diameter is selected to be 0.05-0.1mm, and a low-density arrangement is used to disperse strong light through large, sparse dots. On the light guide plate 4, in the area farther from the LED strip 3, the dot diameter is selected to be 0.02-0.04mm, and a high-density arrangement is used to compensate for weak light through small, dense dots. Simultaneously, the dot size on the light guide plate 4 is uniformly varied, and the dots are staggered to achieve uniform overall brightness.

[0035] When processing the dots on the light guide plate 4, the laser power is set between 40% and 70% to control the dot depth, avoiding uneven dot depth due to insufficient power or carbonization of the material due to excessive power. The scanning speed is set between 3000 and 4000 mm / s to balance efficiency and quality, avoiding missed dots due to excessive speed and low efficiency due to excessive speed. The dot frequency is set between 20 and 40 kHz to control the dot density. The above parameters can be dynamically adjusted according to the light guiding uniformity of the light guide plate 4 to balance various parameters and ensure that the overall brightness uniformity of the light guide plate 4 is >87%.

[0036] The method of use in this embodiment is as follows: First, clean the light guide plate 4. Then, apply acrylic-specific adhesive to the edge of the light guide plate 4 at the position where the first limiting strip 9 is installed. Apply a layer to the first limiting strip 9 as well, and then align and attach it. Attach one first limiting strip 9 to each of the left and right sides of the light guide plate 4, and then wait for the adhesive to cure. After the adhesive has cured, align the assembled light guide plate 4 and the first limiting strip 9 from the side with the slotted position of the connecting profile 2 and insert them into the second slot 8 and the limiting slot 10. Then, push the LED light strip 3 into the first slot 7 on the connecting profile 2 in the same manner. Finally, pass the power cable of the LED light strip 3 through the wire hole 15. Next, fix the base 1 to the mounting surface using connecting screws 17. Then, align the sliding groove 6 on the assembled connecting profile 2 with the sliding block 5 below the base 1, and push the connecting profile 2 into the base 1 from the side. After the two sides are aligned, insert the side sealing plates 14 into the corresponding side sealing grooves 13 and push them in from the slots on both sides of the connecting profile 2 to fix it and prevent the overall structure from sliding. Then, lead the power cord of the LED light strip 3 out from the wiring groove 16 and connect it to an external power source, and it is ready for use.
