Description

Technical Field

[0001] This utility model relates to the field of COB light strips, and in particular to a COB light strip with an external ceiling-mounted structure. Background Technology

[0002] Currently, Chinese patent CN220249844U discloses a COB light strip, relating to the field of LED light strip technology. This utility model includes a protective layer, with a support pin penetrating through the protective layer. One end of the support pin is connected to a support plate, and a reinforcing rod penetrates through the support plate, with one end of the reinforcing rod connected to a reinforcing plate. This utility model, through the setting of the support plate and support pin, uses double-sided adhesive to stick the support plate to the ceiling. At this time, the substrate and the light strip move downward away from the support plate due to gravity. Since the substrate is away from the double-sided adhesive, the heat inside the substrate is prevented from affecting the adhesion of the double-sided adhesive. At the same time, the gap between the substrate and the support plate increases the heat dissipation surface of the substrate, which is convenient for the COB light strip to dissipate heat when installed in a narrow space. Furthermore, since both the support plate and the support pin are made of heat-insulating silicone, it is convenient for the COB light strip to be rolled up while further reducing the heat absorbed by the double-sided adhesive, which is convenient for the COB light strip to dissipate heat and prevents the double-sided adhesive from absorbing heat and decreasing its adhesion.

[0003] COB (Chip-on-Board) LED strips are flexible lighting products that utilize chip-level packaging technology. By directly mounting light-emitting chips onto a substrate to form continuous light-emitting units, they feature uniform light emission, no obvious dark areas, high luminous efficiency, and a thin and light size. They can be cut or bent into different shapes according to needs and are widely used in indoor and outdoor decorative lighting, commercial displays, and home ambiance creation. They can provide a soft and stable lighting effect to the space. However, existing COB LED strips are often difficult to quickly fix to the installation base during installation. Furthermore, when applying the strip to the installation surface, manual pressing can easily result in uneven force, leading to air bubbles, wrinkles, or partial gaps between the strip and the installation surface. This not only affects installation efficiency but also reduces the lifespan and luminous effect of the strip, making it inconvenient for users. Utility Model Content

[0004] The main purpose of this utility model is to provide a COB light strip with an external ceiling-mounted structure, which aims to solve the problems of existing COB light strips, such as difficulty in quickly fixing the installation base during installation, and uneven force when manually pressing the light strip against the installation surface, resulting in air bubbles, wrinkles or partial suspension between the light strip and the installation surface. This not only affects the installation efficiency, but also easily reduces the lifespan and luminous effect of the light strip, and is inconvenient for users.

[0005] To achieve the above objectives, this utility model proposes a COB light strip with an externally mounted ceiling structure, comprising a substrate, a pre-installed bolt movably connected to the inner wall of the substrate, a light strip assembly disposed on the inner wall of the substrate, a diffuser plate movably connected to the inner wall of the substrate, a movable plate disposed at the bottom of the substrate, a flattening mechanism disposed at the top of the movable plate, the top of the flattening mechanism contacting the bottom of the light strip assembly, and a hand handle bolted to the bottom of the movable plate.

[0006] Preferably, the flattening mechanism includes a pressure roller, a bearing, and a rotating shaft. The surface of the rotating shaft is fixedly connected to the inner wall of the bearing, the surface of the rotating shaft is bolted to the inner wall of the pressure roller, and the top of the pressure roller contacts the bottom of the light strip assembly.

[0007] Preferably, an annular block is fixedly connected to the surface of the bearing, a connecting block is bolted to the bottom of the annular block, and the bottom of the connecting block is bolted to the top of the movable plate.

[0008] Preferably, a positioning block is bolted to the top of the movable plate, and the surface of the positioning block is slidably connected to the inner wall of the substrate.

[0009] Preferably, the surface of the handheld handle is covered with a rubber sleeve, and the inner wall of the base plate is provided with a sliding groove that cooperates with the positioning block.

[0010] Preferably, an adhesive component is bonded to the top of the light strip assembly, and the top of the adhesive component is bonded to the inner wall of the substrate.

[0011] Preferably, the top of the substrate is provided with an adhesive coating groove, and the inner wall of the substrate is provided with countersunk holes for use with pre-installed bolts.

[0012] Preferably, sliders are bolted to both the front and rear sides of the diffuser, and the surface of the sliders is engaged with the inner wall of the substrate.

[0013] In this invention, a substrate, pre-installed bolts, a light strip assembly, a diffuser plate, a movable plate, a flattening mechanism, and a handheld rod are provided. During use, the pre-installed bolts are rotated on the inner wall of the substrate to secure it to the mounting base, providing reliable support for the light strip assembly installation. When installing the light strip assembly, one end is first installed on the inner wall of the substrate. Then, the handheld rod drives the movable plate and flattening mechanism to move synchronously, enabling precise flattening of the light strip assembly. This effectively eliminates air bubbles, wrinkles, or poor adhesion between the light strip and the substrate, improving installation efficiency and quality. The diffuser plate evenly scatters the light emitted by the light strip assembly after installation, preventing glare and enhancing the softness and comfort of the lighting effect.

[0026] This utility model provides a COB light strip with an external ceiling-mounted structure, which aims to solve the problems of existing COB light strips, such as difficulty in quickly fixing the installation base during installation, and uneven force when manually pressing the light strip against the installation surface, resulting in air bubbles, wrinkles or partial suspension between the light strip and the installation surface. This not only affects the installation efficiency, but also easily reduces the lifespan and luminous effect of the light strip, and is inconvenient for users.

[0027] like Figure 1-5 As shown in the figure, the COB light strip with an external ceiling-mounted structure provided by this utility model includes a substrate 1, a pre-installed bolt 3 movably connected to the inner wall of the substrate 1, a light strip assembly 4 provided on the inner wall of the substrate 1, a diffuser plate 5 movably connected to the inner wall of the substrate 1, a movable plate 6 provided at the bottom of the substrate 1, a flattening mechanism 2 provided at the top of the movable plate 6, the top of the flattening mechanism 2 contacting the bottom of the light strip assembly 4, and a hand handle 7 bolted to the bottom of the movable plate 6.

[0028] In this utility model, a base plate 1, pre-installed bolts 3, a light strip assembly 4, a diffuser plate 5, a moving plate 6, a flattening mechanism 2, and a handheld rod 7 are provided. During use, the pre-installed bolts 3 are rotated on the inner wall of the base plate 1 to facilitate fixing the base plate 1 to the mounting foundation, providing reliable support for the installation of the light strip assembly 4. When installing the light strip assembly 4, one end of the light strip assembly 4 is first installed on the inner wall of the base plate 1. Then, the handheld rod 7 is used to drive the moving plate 6 and the flattening mechanism 2 to move synchronously, which can perform a precise flattening operation on the light strip assembly 4, effectively eliminating the problems of air bubbles, wrinkles, or poor adhesion between the light strip and the base plate 1, improving installation efficiency and installation quality. The diffuser plate 5 can evenly scatter the light emitted by the light strip assembly 4 after installation, avoiding glare and improving the softness and comfort of the lighting effect.

[0029] Please refer to the following: Figure 5The flattening mechanism 2 includes a pressure roller 201, a bearing 202, and a rotating shaft 203. The surface of the rotating shaft 203 is fixedly connected to the inner wall of the bearing 202, and the surface of the rotating shaft 203 is bolted to the inner wall of the pressure roller 201. The top of the pressure roller 201 contacts the bottom of the LED strip assembly 4. In this embodiment, by setting the pressure roller 201, bearing 202, and rotating shaft 203, the pressure roller 201 can rotate flexibly by utilizing the cooperation between the rotating shaft 203 and the bearing 202. When the hand lever 7 moves the moving plate 6, the pressure roller 201 flattens the LED strip assembly 4 in a rolling manner. Compared with sliding flattening, this reduces friction and avoids scratching damage to the surface of the LED strip assembly 4. At the same time, rolling pressure can make the LED strip assembly 4 fit more evenly with the substrate 1, further improving the installation effect.

[0030] For further information, please continue to refer to [link / reference]. Figure 5 An annular block 8 is fixedly connected to the surface of the bearing 202, and a connecting block 9 is bolted to the bottom of the annular block 8. The bottom of the connecting block 9 is bolted to the top of the moving plate 6. In this embodiment, by setting the annular block 8 and the connecting block 9, the annular block 8 and the connecting block 9 on the surface of the bearing 202 securely connect the flattening mechanism 2 to the moving plate 6, which enhances the installation strength and stability of the flattening mechanism 2, ensures that the pressure roller 201 will not shake or shift due to force during the flattening of the light strip assembly 4, ensures the reliability and consistency of the flattening operation, and extends the service life of the flattening mechanism 2.

[0031] Please continue to refer to this. Figure 4 A positioning block 10 is bolted to the top of the movable plate 6, and the surface of the positioning block 10 is slidably connected to the inner wall of the base plate 1. In this embodiment, by setting the positioning block 10, the position of the movable plate 6 is fixed by the positioning block 10 during use, which facilitates the subsequent restriction of the movement path of the movable plate 6 by the positioning block 10, and facilitates the stable displacement of the movable plate 6.

[0032] Please refer to Figure 4 A rubber sleeve 11 is fitted onto the surface of the handheld lever 7, and a sliding groove 12 is formed on the inner wall of the base plate 1 to cooperate with the positioning block 10. In this embodiment, by providing the rubber sleeve 11, the handheld lever 7 is fitted onto the surface of the handheld lever 7 during use, which facilitates stable handheld operation by the operator. The sliding groove 12 formed on the inner wall of the base plate 1 allows the positioning block 10 to slide along the inner wall of the base plate 1.

[0033] Additionally, please refer to Figure 2 An adhesive component 13 is bonded to the top of the light strip assembly 4, and the top of the adhesive component 13 is bonded to the inner wall of the substrate 1. In this embodiment, by providing the adhesive component 13, it is convenient for the light strip assembly 4 to be bonded to the inner wall of the substrate 1, thus facilitating the installation of the light strip assembly 4 and the substrate 1.

[0034] Additionally, please refer to Figure 3 The substrate 1 has an adhesive application groove 14 on its top, and a countersunk hole 15 for use with the pre-installed bolt 3 is provided on the inner wall of the substrate 1. In this embodiment, the adhesive application groove 14 on the top of the substrate 1 facilitates the subsequent application of adhesive to the inner wall of the adhesive application groove 14, ensuring that the substrate 1 can be installed in multiple ways. The countersunk hole 15 on the inner wall of the substrate 1 facilitates the subsequent rotation of the pre-installed bolt 3 on the inner wall of the substrate 1 through the countersunk hole 15.

[0035] Additionally, please refer to Figure 2 Slider 16 is bolted to both the front and rear sides of the diffuser plate 5, and the surface of the slider 16 engages with the inner wall of the substrate 1. In this embodiment, by setting the slider 16, the position of the slider 16 and the diffuser plate 5 is fixed during use, which facilitates the subsequent installation of the diffuser plate 5 on the inner wall of the substrate 1 by driving the slider 16, thus completing the installation of the diffuser plate 5.
