Technical Field

[0001] This utility model relates to the field of lighting technology, specifically a frameless panel light suitable for ultra-low ceiling structures. Background Technology

[0002] In North America, ultra-thin panel lights are widely used as an important auxiliary lighting device in various commercial spaces and homes. These ultra-thin panel lights, with their slim design and efficient lighting performance, have become the first choice for many interior designers and lighting experts. They not only provide even and soft light, but also blend perfectly into modern minimalist or simple decorating styles, enhancing the overall aesthetics and quality of the home.

[0003] However, the limited ceiling height restricts the installation height, only accommodating 12.5 mm (0.5 inch) thick fireproof light fixtures. This poses a significant challenge to the installation of the light fixtures. Therefore, recessed light fixtures cannot be installed due to the excessive height of the power supply box. Currently, surface-mounted light fixtures are commonly used in the market. However, this method has problems such as larger vertical dimensions of the light fixtures and insufficient aesthetic appeal.

[0004] Based on this, this utility model designs a frameless panel light suitable for ultra-low ceiling structures to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a frameless panel light suitable for ultra-low ceiling structures, in order to solve the problems mentioned in the background art.

[0007] Preferably, the LED driver is fixedly connected to the heat sink body by the driver fixing screw, and the LED driver is electrically connected to the LED light source module.

[0008] Preferably, the top plane of the heat sink lamp body is recessed by 6.5mm, and a protrusion is provided at the recessed edge of the top of the heat sink lamp body. The bottom of the front ring EVA is bonded to the protrusion on the top of the heat sink lamp body with adhesive backing.

[0009] Preferably, the height difference between the top plane of the front ring EVA and the highest point of the top of the driver rear cover is 9.2 mm.

[0010] Preferably, there are two mounting springs, which are symmetrically arranged at the bottom of the left and right sides of the driver rear cover, and the mounting springs are fixedly connected to the driver rear cover and the heat sink body by the driver fixing screws.

[0011] Preferably, the diffuser plate is adapted to the opening at the bottom of the heat sink body, and the diffuser plate is engaged with the heat sink body by a snap fastener at the top edge.

[0023] 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.

[0024] Example 1

[0025] Please see Figure 1 - Figure 6Example 1 illustrates a frameless panel light suitable for ultra-low ceiling structures, comprising an adapter mounting plate 1. A heat dissipation lamp body 8 is fixedly connected to the bottom of the adapter mounting plate 1. Several drive fixing screws 2 are threadedly connected to the top of the heat dissipation lamp body 8. A driver back cover 3 is provided at the center of the top of the heat dissipation lamp body 8. The driver back cover 3 is fixedly connected to the heat dissipation lamp body 8 by the drive fixing screws 2. An installation spring 4 is embedded between the driver back cover 3 and the heat dissipation lamp body 8. An LED driver 6 is embedded in the cavity at the bottom of the driver back cover 3. An input wire 5 is soldered onto the LED driver 6. A front ring EVA 7 is matched and connected to the edge of the top of the heat dissipation lamp body 8. An LED light source module 9 is matched and connected to the top of the cavity at the bottom of the heat dissipation lamp body 8. Several LED light source fasteners 10 are arranged circumferentially at equal intervals on the LED light source module 9. The LED light source module 9 is fixedly connected to the heat dissipation lamp body 8 by the LED light source fasteners 10. A diffuser plate 11 is connected to the opening at the bottom of the heat dissipation lamp body 8.

[0026] Please see Figure 4 and Figure 5 The LED driver 6 in the figure is fixedly connected to the heat sink lamp body 8 by the driving fixing screw 2, and the LED driver 6 is electrically connected to the LED light source module 9.

[0027] In this embodiment, firstly, the input wire 5 of the lamp is soldered to the LED driver 6. Then, the driver fixing screw 2 is used to limit the LED driver 6 and fix it to the heat sink lamp body 8. Subsequently, the LED light source module 9 is installed on the heat sink lamp body 8 using the LED light source fastener 10, and the front ring EVA 7 with adhesive backing is pasted to the top of the heat sink lamp body 8. The diffuser plate 11 is then snapped onto the lamp head semi-finished product to ensure that the wiring connection between the LED light source module 9 and the LED driver 6 is correct. Finally, the driver back cover 3 is fixed to the lamp head semi-finished product using the driver fixing screw 2, and the mounting spring 4 is fixed between the driver back cover 3 and the lamp head semi-finished product using the product thickness difference design, thereby completing the assembly of the entire lamp.

[0028] It should be noted that the LED driver 6 has an input wire 5 soldered on it. The input wire 5 is used to connect the input wire 5 to the power supply to ensure that the LED driver 6 can be powered normally. The LED driver 6 is electrically connected to the LED light source module 9, and the LED driver 6 drives the 9 to realize the lighting function.

[0029] Example 2

[0030] Please see Figure 4 and Figure 5Example 2 is described below. This embodiment further illustrates Example 1. In the figure, the top plane of the heat dissipation lamp body 8 is recessed by 6.5mm, and a protrusion is provided at the edge of the recessed top of the heat dissipation lamp body 8. The bottom of the front ring EVA7 is bonded to the protrusion on the top of the heat dissipation lamp body 8 with adhesive backing.

[0031] Furthermore, the height difference between the top plane of the front ring EVA7 and the highest point of the top of the driver rear cover 3 is 9.2mm;

[0032] In this embodiment, the top plane of the heat dissipation lamp body 8 is lowered by 6.5mm, making the installation space of the LED driver 6 more compact. At the same time, a protrusion is provided at the edge of the lowered top of the heat dissipation lamp body 8, and the bottom of the front ring EVA7 is glued to the protrusion on the top of the heat dissipation lamp body 8 with adhesive. This design not only ensures the heat dissipation performance of the lamp, but also further reduces the overall height, allowing the lamp to adapt to narrower installation spaces.

[0033] It should be noted that the top plane of the heat sink body 8 is recessed by 6.5mm so that the PCB board of the LED driver 6 can directly contact the heat sink body 8. This not only saves space and height but also improves heat dissipation efficiency. Ultimately, the overall height of the driver back cover 3 (i.e. the part that needs to be installed in the fireproof barrel) is only 9.2mm, which allows it to perfectly fit the 12.5mm high fireproof barrel and solves the problem that traditional lamps cannot be installed due to the excessive height of the power supply box.

[0034] Example 3

[0035] Please see Figure 4 and Figure 7 Example 3 is described below. This embodiment further describes Example 2. In the figure, there are two mounting springs 4. The two mounting springs 4 are symmetrically arranged at the bottom of the left and right sides of the driver rear cover 3. The mounting springs 4 are fixedly connected to the driver rear cover 3 and the heat sink body 8 by the driver fixing screws 2.

[0036] Furthermore, the diffuser plate 11 is adapted to the opening at the bottom of the heat sink 8, and the diffuser plate 11 is engaged with the heat sink 8 by a buckle at the top edge.

[0037] In this embodiment, the mounting springs 4 provided on the left and right sides of the driver back cover 3 can quickly and easily fix the lamp to the ceiling during lamp installation, which not only improves installation efficiency but also ensures the stability of the lamp during installation. The diffuser plate 11 further optimizes the distribution of light, making the light more uniform and soft.

[0038] It should be noted that the diffuser plate 11 is adapted to the opening at the bottom of the heat sink lamp body 8 and is connected to the heat sink lamp body 8 by a buckle at the top edge. This not only ensures the uniform diffusion of light but also improves the lighting efficiency of the lamp, making the light softer and avoiding glare, thus providing users with a more comfortable lighting environment.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
