Description

Technical Field

[0001] This utility model belongs to the field of panel light technology, and specifically relates to a direct-lit panel light. Background Technology

[0002] In modern indoor lighting, panel lights are widely used due to their uniform and soft light and simple and beautiful appearance. However, existing panel lights have some shortcomings. For example, some panel lights have poor light uniformity, easily producing dark areas or bright spots, affecting the lighting effect and visual comfort; some panel lights have poor heat dissipation performance, leading to a shortened lifespan and posing safety hazards; in addition, in terms of installation structure, panel lights are installed by engaging with the ceiling frame through edge clips, which may result in detachment; and traditionally, the light strips are fixed inside the lamp housing with screws, making disassembly and replacement relatively troublesome. Therefore, it is necessary to improve existing panel lights to meet the market demand for high-quality, high-performance lighting fixtures. Utility Model Content

[0003] The purpose of this invention is to provide a direct-lit panel light to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a direct-lit panel light, comprising a main lamp housing, wherein the interior of the main lamp housing is uniformly distributed with grid grooves, and multiple light strips are evenly distributed within the grid grooves. Each light strip is uniformly provided with multiple LED beads, and plastic clips for mounting the light strips are provided at both ends of the light strips. The plastic clips are fixedly connected to the main lamp housing, and the light strips are snapped onto the inner side of the plastic clips. A frame is fixedly connected to the bottom perimeter of the main lamp housing by bolts. A light guide plate is pressed between the main lamp housing and the frame. The perimeter of the frame is bent to form a folded edge, and the inner side of the folded edge forms a mounting groove. A snap-fit ​​protrusion is provided on the inner surface of the folded edge, and an elastic clamping component is provided on one side of the mounting groove.

[0005] Preferably, the elastic clamping component includes a retraction groove formed on one side of the mounting slot, a clamping strip is slidably disposed in the retraction groove, a spring is connected between the clamping strip and the retraction groove, and the other end of the clamping strip extends horizontally to the outside of the retraction groove.

[0006] Preferably, the end of the pressing strip extending to the outside of the return groove has an arc-shaped surface structure, and both ends of the pressing strip are provided with guide sliders that limit the pressing strip to slide only in a horizontal straight line. Both ends of the return groove are provided with guide grooves that match the guide sliders.

[0007] Preferably, thermally conductive silicone is also provided between the light strip and the main light housing, and the thermally conductive silicone is bonded to the corresponding mesh groove.

[0008] Preferably, a terminal block is provided on the outer side of the main lamp housing, and the terminal block is connected in parallel with each lamp strip.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] The main lamp housing of this utility model is designed with a grid groove, which allows the light strips to be evenly distributed in the grid groove, effectively scattering the light evenly. In addition, the grid groove is designed with plastic clips for locking and installing the light strips, realizing quick disassembly and replacement of the light strips.

[0011] Thermally conductive silicone is designed between the light strip and the main light housing to enable the light strip to dissipate heat quickly and ensure its service life;

[0012] A retractable clamping strip is designed on one side of the mounting slot. When the entire panel light is installed, after the folded edge is inserted into the corresponding groove of the profile steel frame, it not only engages with the profile steel frame through the engaging protrusion, but also the rest of the profile steel frame extends into the mounting slot. This can compress and force the clamping strip back, and then a spring will press the clamping strip against the side of the profile steel frame, making the folded edge more stable in the groove of the profile steel frame and preventing it from falling off.

[0018] 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.

[0019] Example 1

[0020] Please see Figure 1 and Figure 4 This utility model provides a technical solution: a direct-lit panel light, including a main lamp housing 2, which is made of extruded aluminum alloy, square in shape, with a side length of 60 cm. Its frame is designed as a straight line, providing good structural strength and heat dissipation performance. The four corners of the main lamp housing 2 are rounded, which is not only aesthetically pleasing but also prevents scratches to people and objects during installation and use. The interior of the main lamp housing 2 has evenly distributed grid grooves 8 for fixing and supporting other components. Multiple light strips 9 are evenly distributed within the grid grooves 8, and each light strip 9 is evenly equipped with multiple LED beads 10, using surface-mount LED beads, which have the advantages of high brightness, low power consumption, and long lifespan. Both ends are provided with plastic clips 11 for installing light strips 9. The plastic clips 11 are fixedly connected to the main lamp housing 2. The light strips 9 are snapped into the inner side of the plastic clips 11. The bottom four edges of the main lamp housing 2 are fixedly connected with a frame 1 by bolts. A light guide plate 3 is pressed between the main lamp housing 2 and the frame 1. The light guide plate 3 is made of PS material with high light transmittance and a thickness of 1.2 mm. Its surface is microstructured and can effectively scatter light evenly to the entire panel area. The four edges of the frame 1 are bent to provide folded edges 4. The inner side of the folded edges 4 forms a mounting groove 7. The inner surface of the folded edges 4 is provided with a snap-fit ​​protrusion 14. An elastic clamping component is provided on one side of the mounting groove 7.
