Description

Technical Field

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

[0002] In traditional LED downlight designs, the fixing of aluminum reflectors typically involves two main structural components: the lamp body heat sink and the lamp body face ring. As a core component, the aluminum reflector's primary function is to improve luminous efficiency through reflection, ensuring light travels in the intended direction, thereby enhancing illumination and reducing light loss. In traditional designs, the aluminum reflector is fixed by placing it between the lamp body heat sink and the lamp body face ring, then clamping it from above and below with mechanical fasteners such as screws. This structural design requires precise fit between the lamp body and the face ring to ensure the reflector's stability and optical performance.

[0003] However, this traditional fixing method has some drawbacks. First, the structure is relatively complex because it requires ensuring a precise fit between the two parts, which increases the difficulty of manufacturing. Second, the manufacturing process is complex because additional steps are needed to assemble and fix the reflector cup, which not only increases production time but may also require more complex equipment and higher technical proficiency. Finally, this design often leads to higher costs because the complexity of the structure increases material and labor costs, and may also involve more quality control and inspection steps to ensure product reliability.

[0004] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0027] Please see Figures 1 to 4 This utility model provides an LED downlight, including a lamp body 1 and a lampshade 2, a fixing ring 3, a reflector 4, and a lamp plate 5 disposed within the lamp body 1; the top of the reflector 4 has a connecting through hole, the lampshade 2 is located inside the reflector 4, the top of the lampshade 2 passes through the connecting through hole and is engaged with the fixing ring 3, and the reflector 4 is fixed between the lampshade 2 and the fixing ring 3; the fixing ring 3 is fixedly connected to the top of the lamp body 1, and the lamp plate 5 is located between the fixing ring 3 and the top of the lamp body 1.

[0028] This application discloses an LED downlight that integrates three components—lamp cover 2, fixing ring 3, and reflector 4—by fixing the lamp cover 2 and fixing ring 3 to the lamp body 1. This integrated component simplifies the installation process of the reflector 4 and lamp cover 2 by fixing the fixing ring 3 inside the lamp body 1, eliminating the complex alignment steps in traditional assembly methods and significantly improving assembly efficiency. In addition, due to the simplification of the installation and mating structure, the structure of the lamp body 1 is also simplified, effectively reducing processing and material costs while ensuring that the quality, performance, and reliability of the final product are not affected.

[0029] In this embodiment, the reflector 4 is an aluminum reflector, the lampshade 2 is an injection-molded lampshade, the fixing ring 3 is an injection-molded fixing ring, and the lamp body 1 is a one-piece stamped structure. This design makes the overall structure of the LED downlight compact, lightweight, and easy to install and maintain. The aluminum reflector has good thermal conductivity, which can effectively conduct away the heat generated by the LED chip, thereby extending the service life of the LED lamp. The use of the injection-molded lampshade and injection-molded fixing ring not only improves the appearance quality of the LED downlight but also enhances its impact resistance and weather resistance. The one-piece stamped structure of the lamp body 1 ensures the overall strength and stability of the lamp while reducing production costs.

[0030] Further, please refer to Figure 1 and Figure 2The top of the lamp body 1 has a plurality of first connecting holes, the lamp plate 5 has a plurality of second connecting holes 51, and the top of the fixing ring 3 has a plurality of third connecting holes 31. The plurality of first connecting holes, the plurality of second connecting holes 51 and the plurality of third connecting holes 31 correspond one-to-one and are connected by fasteners.

[0031] In this embodiment, the fastener is a screw, and the first connecting hole, the second connecting hole 51, and the third connecting hole 31 each include three fasteners. The fastener passes through the first connecting hole, the second connecting hole 51, and the third connecting hole 31 in sequence and is connected to the nut to achieve a fixed connection between the lamp body 1, the lamp plate 5, and the fixing ring 3. This connection method is simple and reliable, effectively improving the stability and safety of the entire lamp structure, and also facilitating subsequent disassembly and maintenance, thus reducing maintenance costs. After the fixing ring 3 is fixedly installed, the fixed connection between the reflector cup 4 and the lamp cover 2 and the lamp body 1 is completed. That is, the component design between the fixing ring 3, the reflector cup 4, and the lamp cover 2 not only simplifies the installation steps but also improves the overall aesthetics and sealing of the lamp, thereby improving the lighting effect and service life of the lamp.

[0032] Further, please refer to Figure 1 and Figure 4 The LED downlight also includes a top cover 6, which is snapped onto the top of the lamp body 1; a receiving groove is provided between the top cover 6 and the top of the lamp body 1, a first wire hole 11 is provided on the top of the lamp body 1, and a second wire hole is provided on the side of the top cover 6. The receiving groove, the first wire hole 11, and the second wire hole are used to realize the electrical connection between the lamp board 5 and the external power supply device.

[0033] In this embodiment, the top cover 6 is an injection-molded top cover. The bottom of the top cover 6 is provided with a plurality of connecting blocks 22, and the top edge of the lamp body 1 is provided with a plurality of connecting slots 33. The connecting blocks 22 and the connecting slots 33 cooperate to connect the top cover 6 and the lamp body 1.

[0034] In this embodiment, a snap-fit ​​structure between the top cover 6 and the lamp body 1 is designed to achieve a quick and stable assembly method, improving assembly efficiency and reducing assembly costs. At the same time, the snap-fit ​​structure also facilitates subsequent disassembly and maintenance, improving the maintainability of the LED downlight. Secondly, the receiving groove, the first wire hole 11, and the second wire hole opened between the top cover 6 and the lamp body 1 provide a convenient channel for the electrical connection between the lamp board 5 and the external power supply device, ensuring the stability and safety of current transmission, and avoiding problems such as wiring confusion and poor contact that may exist in traditional wiring methods, thereby improving the reliability and service life of the LED downlight during operation. In addition, the use of injection-molded top cover not only reduces production costs, but also, due to the good impact resistance and anti-aging properties of the injection-molded top cover, enables the top cover 6 to maintain stable performance during long-term use.

[0035] Further, please refer to the figure, the LED downlight also includes a power cord 9, the power cord 9 includes a mounting base 91, one end of the power cord 9 is electrically connected to the lamp board 5 through the first wire hole 11, the mounting base 91 is fixedly connected to the top of the lamp body 1, and the other end of the power cord 9 is located outside the second wire hole for connecting to an external power supply device.

[0036] In this embodiment, the external power supply device can be an electrical socket for connecting to mains power; the fixing base 91 is bolted to the top of the lamp body 1, which can effectively avoid poor contact caused by wire misalignment and improve the stability and reliability of the lamp board 5 during operation; in addition, the electrical connection between the power cord 9 and the lamp board 5 is achieved through the first wire hole 11 and the second wire hole, which ensures the stability and reliability of the connection and avoids poor contact caused by frequent plugging and unplugging.

[0037] Further, please refer to Figure 4 The lower surface of the reflector cup 4 is flush with the lower surface of the lamp body 1, and the vertical distance from the lamp plate 5 to the bottom edge of the reflector cup 4 forms a 30° light-blocking angle.

[0038] In this embodiment, the reflector cup 4 adopts a deep cup structure design, which increases the vertical distance between the light source and the edge of the opening of the reflector cup 4, forming a 30° light-shielding angle. The light-shielding angle refers to the angle range in which the light emitted from the light source is blocked inside the reflector cup 4 and cannot be directly emitted. Here, this angle is specifically 30 degrees. Through the deep cup structure design, the possibility of the human eye looking directly at the light source is significantly reduced, effectively reducing the occurrence of direct glare. Specifically, the light emitted by the LED beads on the light panel 5 first passes through the lampshade 2, and after being reflected by the reflector cup 4, the light is evenly scattered. This evenly scattered light avoids directly shining into the human eye, thereby greatly reducing glare and providing users with a more comfortable lighting environment. It effectively avoids the discomfort caused by glare when looking up at the light source and improves the overall user experience.

[0039] Further, please refer to Figure 1 The LED downlight also includes reflective paper 7, which is located inside the lampshade 2, and the top of the reflective paper 7 is fixedly connected to the lamp panel 5.

[0040] In this embodiment, reflective paper 7 is used to improve the brightness and lumens of the LED downlight. Its working principle is to use optical principles to reflect light back to the light source. In the LED downlight, reflective paper 7 is located inside the lampshade 2 and is fixedly connected to the lamp board 5. When the LED light on the lamp board 5 emits light, reflective paper 7 can reflect and focus the light, so that the light is more concentrated on the area that needs to be illuminated, thereby improving the lighting effect and brightness.

[0041] Further, please refer to Figure 1 The LED downlight also includes a waterproof gasket 8, which is located between the fixing ring 3 and the lamp plate 5. The side of the waterproof gasket 8 is provided with a plurality of clearance grooves for avoiding the second connection hole 51.

[0042] In this embodiment, the waterproof gasket 8 is located between the fixing ring 3 and the lamp plate 5 to prevent moisture or other liquids from seeping into the lamp body 1, thereby protecting the circuit and electronic components from moisture damage. The waterproof gasket 8 ensures the stable operation of the LED downlight in a humid environment through its sealing performance. In addition, the multiple clearance grooves on the side of the waterproof gasket 8 to avoid the second connection hole 51 allow the fixing ring 3 and the lamp plate 5 to be connected by fasteners without affecting the sealing effect of the waterproof gasket 8. This ensures both the stable installation of the lamp and the waterproof performance of the LED downlight.

[0043] Further, please refer to Figure 1 and Figure 2The top of the fixing ring 3 is provided with a plurality of positioning posts 32, the waterproof gasket 8 is provided with a plurality of first positioning holes 81, and the lamp plate 5 is provided with a plurality of second positioning holes; the plurality of positioning posts 32 are respectively connected to the plurality of first positioning holes 81 and the plurality of second positioning holes one by one.

[0044] In this embodiment, the positioning post 32 is integrally formed with the fixing ring 3. Three positioning posts 32 are evenly arranged on the top circumference of the fixing ring 3. Three second positioning holes are correspondingly opened on the lamp plate 5, and three first positioning holes 81 are correspondingly opened on the waterproof gasket 8. By cooperating with the positioning posts 32 to connect the first positioning holes 81 and the second positioning holes, the lamp plate 5, the waterproof gasket 8 and the fixing ring 3 can be precisely aligned during assembly, thereby ensuring the accurate installation position of the lamp plate 5, improving assembly efficiency and product quality. In addition, it can also prevent the lamp plate 5 from shifting due to vibration or external force during use, thereby ensuring the stability and reliability of the LED downlight during operation.

[0046] In this embodiment, four limiting posts 21 and four locking blocks 22 are evenly arranged on the upper periphery of the lampshade 2. The locking blocks 22 are located between two adjacent limiting posts 21. The upper periphery of the reflector cup 4 is correspondingly provided with four limiting holes 42 and four locking through holes 41. The inner periphery of the top of the fixing ring 3 is correspondingly provided with four limiting grooves and four locking slots 33. The multiple limiting posts 21, multiple limiting holes 42 and multiple limiting grooves are connected one-to-one to form a stable three-dimensional support system, ensuring the precise alignment and tight fit between the three components of the fixing ring 3, reflector cup 4 and lampshade 2. The multiple locking blocks 22, multiple locking through holes 41 and multiple locking slots 33 are corresponding one-to-one, and the locking blocks 22 are tightly locked with the locking slots 33 through the locking through holes 41.
