Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to an LED panel light. Background Technology

[0002] LED panel lights are widely used in lighting scenarios such as homes, offices, and commercial spaces due to their soft light and simple appearance. However, existing products still have shortcomings in practicality: the installation methods are mostly fixed recessed or ceiling-mounted, which lacks flexibility when adapting to different ceiling thicknesses and mounting hole positions, and disassembly and maintenance are time-consuming; the heat dissipation structure is mostly a single back plate heat dissipation, which makes it easy for the heat generated by the LED light source to accumulate, resulting in luminous efficiency decay and shortened lifespan; some products have poor uniformity of the light-emitting surface, with dark areas or glare problems, and the angle adjustment function is missing, making it difficult to adapt to different lighting needs; at the same time, the integration of the lamp body and the driver power supply is low, the wiring is messy, and it occupies installation space. Therefore, there is an urgent need to optimize the structural design of LED panel lights and improve their adaptability and practicality.

[0003] Chinese Patent Publication No. CN213983037U discloses a utility model of an LED panel light, which relates to the field of lighting technology. The LED panel light includes a base, a lampshade, a circuit board, an LED light source, and an optical structure. The base has a receiving cavity, and the lampshade is mounted on the base. The circuit board is disposed in the receiving cavity, and the LED light source is mounted on the circuit board. The optical structure is disposed in the receiving cavity and is used to allow the light emitted by the LED light source to illuminate the lampshade. This design simplifies the overall structure of the LED panel light, facilitates its disassembly and assembly, and helps reduce assembly costs.

[0004] Traditional LED panel lights generally suffer from two major pain points: heat dissipation and glare. Regarding heat dissipation, their simple heat dissipation structures rely on a single heat sink or a few heat sinks to conduct heat, making it difficult to dissipate heat efficiently. This heat tends to accumulate on the circuit board and electronic components, causing the lamp's operating temperature to rise continuously. This not only accelerates the decay of the LED light source but also affects the stable operation of electronic components, leading to frequent brightness drops, flickering, or even damage after prolonged high-load operation. The lifespan is typically only 3-5 years. As for glare, traditional LED panel lights often lack reasonable light guiding and reflection structures, resulting in direct light projection. While some products have simple reflective layers, the reflection angle is singular and the light focusing effect is poor, easily leading to strong direct light and uneven light distribution, producing noticeable glare. This not only causes visual fatigue but can also damage eyesight with prolonged exposure, especially in office and home environments where eye use is prolonged, becoming a key issue affecting the user experience.

[0005] Therefore, we proposed an LED panel light to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide an LED panel light that solves the problems of glare caused by simple heat dissipation structure, inefficient heat conduction, single reflection angle, and poor light focusing effect in the prior art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: An LED panel light includes a housing, a fixing block fixedly connected to the top of the housing, a mounting hole provided on one side of the fixing block, the mounting hole passing through the fixing block and the housing in sequence, a plurality of connecting posts fixedly connected between the fixing block and the housing, four fixing holes provided on the top of the fixing block, the four fixing holes passing through the fixing block, a heat sink provided at the bottom of the housing, a plurality of heat dissipation fins fixedly connected to the top of the heat dissipation fins, and the tops of all the heat dissipation fins being fixedly connected to the inner surface of the housing.

[0008] Preferably, a glass plate is fixedly connected to the bottom of the outer shell, a reflector is provided on the top of the glass plate, the top of the reflector is fixedly connected to the bottom of the heat dissipation shell, a support block is provided at the bottom of the reflector, one side of the support block is fixedly connected to the inner surface of the outer shell, and a light-transmitting hole is opened on one side of the reflector, the light-transmitting hole penetrating the reflector.

[0009] Preferably, a reflective cavity is provided between the glass plate and the reflective plate, and the reflective cavity is connected to the light-transmitting hole.

[0010] Preferably, a circuit board is provided on the top of the reflector, and the circuit board is fixedly connected to the inner surface of the heat sink around its perimeter.

[0011] Preferably, four heat dissipation blocks are provided between the reflector and the heat dissipation shell, the top of each of the four heat dissipation blocks is fixedly connected to the inner surface of the heat dissipation shell, and the bottom of each of the four heat dissipation blocks is bolted to the top of the circuit board.

[0012] Preferably, a plurality of heat dissipation plates are fixedly connected to the outer surfaces of the four heat dissipation blocks, and the plurality of heat dissipation plates are distributed in a circumferential array along the outer surfaces of the heat dissipation blocks.

[0013] This utility model has at least the following beneficial effects: This device employs a multi-layered, high-efficiency heat dissipation system. Through the coordinated action of the heat sink shell, heat sink fins, heat sink blocks, and heat sink plates, heat is conducted and dissipated at multiple levels and points. The heat sink fins adhere to the outer shell to absorb basic heat, the heat sink blocks connect to the circuit board for precise heat conduction, and the heat sink plates expand the contact area to facilitate heat diffusion and prevent localized heat accumulation. Compared to traditional single-structure designs, heat dissipation efficiency is significantly improved, reducing the lamp body's operating temperature, suppressing LED light decay, ensuring stable component operation, extending lifespan, and reducing replacement and maintenance costs.

[0014] This utility model also has the following beneficial effects: This device constructs an anti-glare lighting system through the ingenious combination of a reflector, a reflective cavity, and a light-transmitting aperture. The reflector initially reflects and converges the LED light, avoiding direct glare; the light-transmitting aperture guides the light into the reflective cavity in an orderly manner, and after multiple reflections and mixing, it is projected evenly. The design transforms the light from direct to diffused, softening the intensity, eliminating glare, and providing uniform lighting without bright or dark areas. It is eye-friendly and provides sufficient brightness, making it suitable for office, classroom, and home settings, improving lighting comfort and practicality. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0019] Reference Figure 1-5 An LED panel light includes a housing 1. A fixing block 2 is fixedly connected to the top of the housing 1. A mounting hole 3 is provided on one side of the fixing block 2, and the mounting hole 3 passes through the fixing block 2 and the housing 1 in sequence. Several connecting posts 4 are fixedly connected between the fixing block 2 and the housing 1 to enhance the stability of the connection and prevent loosening after installation. Four fixing holes 5 are provided on the top of the fixing block 2, and the four fixing holes 5 pass through the fixing block 2, which can quickly realize the installation and fixing of the LED panel light and is easy to operate. A heat dissipation shell 6 is provided at the bottom of the housing 1. Several heat dissipation fins 7 are fixedly connected to the top of the heat dissipation shell 6. The top of all the heat dissipation fins 7 are fixedly connected to the inner surface of the housing 1, which can conduct and dissipate the heat generated inside the lamp body in time, effectively reduce the operating temperature of the lamp body, and extend the service life.

[0020] Furthermore, a glass plate 9 is fixedly connected to the bottom of the outer shell 1, which serves both as protection and to ensure that light can pass through normally. A reflector 10 is provided on the top of the glass plate 9. The reflector 10 can reflect and converge the light emitted by the LED, improve the light utilization rate, and reduce light loss. The top of the reflector 10 is fixedly connected to the bottom of the heat sink 6. A support block 8 is provided at the bottom of the reflector 10. One side of the support block 8 is fixedly connected to the inner surface of the outer shell 1. The support block 8 provides stable support for the reflector 10 and prevents the reflector 10 from shifting due to gravity or vibration. A light-transmitting hole 12 is opened on one side of the reflector 10. The light-transmitting hole 12 passes through the reflector 10 and provides a channel for light transmission, ensuring that light can be smoothly projected onto one side of the glass plate 9.

[0021] Furthermore, a reflective cavity 11 is provided between the glass plate 9 and the reflector 10. The reflective cavity 11 is connected to the light-transmitting hole 12, so that the light entering through the light-transmitting hole 12 is reflected multiple times in the reflective cavity 11 before being emitted, further optimizing the uniformity of the light and making the light output effect of the LED panel light softer and brighter, thus improving the lighting experience.

[0022] Furthermore, a circuit board 13 is provided on the top of the reflector 10. The circuit board 13 is fixedly connected to the inner surface of the heat sink 6 around its perimeter, which realizes the stable installation of the circuit board 13 and prevents it from shaking or shifting during the operation or movement of the lamp body. At the same time, the heat sink 6 can quickly remove the heat generated by the circuit board 13 through contact conduction, ensuring the stable operation of the electronic components on the circuit board 13 and reducing the failure rate.

[0023] Furthermore, four heat sinks 14 are provided between the reflector 10 and the heat sink 6. The tops of the four heat sinks 14 are fixedly connected to the inner surface of the heat sink 6, and the bottoms are connected to the circuit board 13 by bolts. This not only further strengthens the installation stability of the circuit board 13, but also efficiently conducts the heat of the circuit board 13 to the heat sink 6, enhancing the heat dissipation effect. The bottoms of the four heat sinks 14 are all connected to the tops of the circuit board 13 by bolts. The arrangement of the four heat sinks 14 realizes multi-point heat conduction, making heat dissipation more balanced and efficient.

[0024] Specifically, several heat sinks 15 are fixedly connected to the outer surfaces of the four heat sinks 14. The heat sinks 15 are arranged in a circumferential array along the outer surface of the heat sinks 14, which greatly increases the contact area between the heat sinks 14 and the air and accelerates the heat dissipation speed. The circumferential array distribution ensures smooth airflow around the heat sinks 15, avoids heat accumulation, further improves the overall heat dissipation efficiency of the LED panel light, and ensures the stability of the light body under long-term high-load operation.

[0025] In summary: After the device is powered on, the lighting and heat dissipation systems operate in tandem: the LED light source emits light, and the reflector 10 first reflects and converges the light to avoid direct glare. The light is then guided through the light-transmitting hole 12 into the reflecting cavity 11 for multiple mixing before penetrating the glass plate 9 for soft projection, achieving glare-free, uniform lighting that is eye-friendly and provides sufficient brightness, suitable for various scenarios. Simultaneously, the heat generated by the circuit board 13 is conducted to the heat sink 14 and the heat sink shell 6 through contact. The circumferential array heat sink 15 on the heat sink 14 increases the contact area and accelerates heat dissipation. The heat sink shell 6 then conducts the heat to the outer shell 1 through the heat dissipation fins 7, forming a multi-layered heat dissipation chain. The connection between the heat sink 14 and the heat sink shell 6 also reinforces the circuit board 13, preventing it from shaking or shifting. With the two systems working in tandem, the heat dissipation system removes the heat generated by the lighting in real time, ensuring stable operation of the components and ultimately achieving a comprehensive effect of efficient lighting, rapid heat dissipation, and long service life.
