In this LED packaging light source structure, a fluorescent glue layer is arranged on the upper side of the light-emitting component, and a distance is formed between the fluorescent glue layer and the edge of the light-emitting component, so that the blue light emitted from the edge of the light-emitting component is directly emitted without passing through the fluorescent glue layer, and after passing through the refraction and reflection of the lens, it returns to the packaging structure and is converted into white light through the internal fluorescent glue layer, so that the overall LED packaging light source structure emits white light with uniform color temperature, avoiding the phenomenon of yellow circles appearing at the edge of the LED light source.

[0004] The above-mentioned LED packaging light source structure has certain defects, such as low heat dissipation efficiency. When the LED light source is used for a long time, the temperature inside the packaging structure rises, resulting in the deviation of the emission spectrum of the LED, thereby changing its color temperature.

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figure 1 - Figure 2 , an embodiment provided by the present utility model: An LED light source packaging structure with uniform light color includes a substrate 1. An installation groove 2 is formed on the surface of the substrate 1. The installation groove 2 is a grooved structure on the surface of the substrate 1 and is used for fixing and installing the lamp board 4 and the heat dissipation component 5. The lamp board 4 is fixedly connected inside the installation groove 2. A plurality of groups of lamp beads 41 arranged in columns are provided on the surface of the lamp board 4. The lamp board 4 is used for installing the lamp beads 41, and a uniform light source is provided through the plurality of groups of lamp beads 41 arranged in an array.

[0032] Refer to Figure 1 - Figure 2, a heat dissipation component 5 is arranged inside the installation groove 2. The heat dissipation component 5 includes a metal plate 51 which is made of brass as a whole. It mainly conducts the heat generated by the lamp board 4 effectively to a larger heat dissipation area to enhance the heat dissipation effect. The metal plate 51 is fixedly connected to the inner wall of the installation groove 2. A thermal conductive glue layer 52 is filled between the metal plate 51 and the lamp board 4. The function of the thermal conductive glue layer 52 is to fill and level the tiny gaps between the metal plate 51 and the lamp board 4, improve the heat conduction efficiency, and ensure that heat energy can be effectively transferred from the lamp beads 41 to the metal plate 51. Two groups of symmetrically arranged heat conduction plates 53 are fixedly connected to the bottom surface of the metal plate 51. The heat conduction plates 53 penetrate and are fixedly connected to the bottom of the substrate 1. The heat conduction plates 53 connect the inside and outside of the entire packaging structure, conduct the heat from the metal plate 51 to the heat dissipation plate 54 for more effective heat dissipation. A plurality of groups of heat dissipation plates 54 distributed in an array are fixedly connected between the bottom ends of the two groups of heat conduction plates 53. The heat dissipation plates 54 increase the heat dissipation surface area, improve the heat radiation and heat dissipation ability, thereby effectively reducing the working temperature of the LED, keeping the stability inside the packaging structure stable. Two groups of symmetrically arranged fans 55 are fixedly connected to the bottom surface of the substrate 1. The fans 55 further enhance the heat dissipation effect of the heat dissipation plates 54 by generating air flow, take away the heat, and ensure that the LED light source can maintain a stable working temperature during long-term operation.

[0033] In summary, through the synergistic effect of the metal plate 51, the thermal conductive glue layer 52, the heat conduction plates 53 and the heat dissipation plates 54, the heat dissipation component 5 conducts and dissipates heat quickly and evenly. The fans 55 further enhance the heat dissipation effect of the heat dissipation plates 54 by generating air flow, extend the service life of the LED light source, and at the same time maintain its optical performance and color uniformity.

[0034] Refer to Figure 1 - Figure 3, a slot 3 is provided on the surface of the substrate 1. The slot 3 is used to accommodate and install the lens cover 6. The lens cover 6 is inserted into the slot 3. A sealing rubber ring 61 is fixedly connected to the bottom of the lens cover 6. The sealing rubber ring 61 helps prevent dust and moisture from entering the LED light source structure and protects the internal components. A rib 62 is fixedly connected to the outer wall of the lens cover 6. The rib 62 forms a protruding part on the outer wall of the lens cover 6, which facilitates the fixing of the lens cover 6 by the limiting component 8. A through groove 7 is provided on the inner wall of the slot 3. A limiting component 8 is arranged inside the through groove 7. The through groove 7 is used for installing and positioning the limiting component 8. The limiting component 8 is used for positioning the lens cover 6 and fixing the lens cover 6 in the slot 3. The limiting component 8 includes a plug board 81. The plug board 81 is slidably connected inside the through groove 7. By sliding the plug board 81 inside, a part of the plug board 81 enters into the slot 3 and contacts the rib 62, so as to clamp the rib 62 in the slot 3 and realize the positioning of the lens cover 6. Convex blocks 82 are fixedly connected to both sides of the plug board 81. Through holes are provided through the side walls of the convex blocks 82, and guide rods 83 are slidably connected in the through holes. The convex blocks 82 and the guide rods 83 are used for guiding the plug board 81 to make the movement of the plug board 81 more stable. One end of the guide rod 83 is fixedly connected to a limit block 84, and the other end of the guide rod 83 is fixedly connected to the side wall of the substrate 1. The limit block 84 is used for limiting the end of the guide rod 83 to prevent the convex block 82 from separating from the guide rod 83. The limit block 84 is elastically connected to the side wall of the substrate 1 through a return spring 85. The return spring 85 is used to provide stable elastic support for the convex block 82 and ensure the limiting effect of the plug board 81 on the rib 62.

[0035] Working principle: When the lens cover 6 needs to be installed into the slot 3, first the user aligns the bottom of the lens cover 6 with the opening of the slot 3, and then gently pushes the lens cover 6 into the slot 3. During the pushing process, the rib 62 will first contact the edge of the slot 3, and as the lens cover 6 is further pushed in, the rib 62 gradually enters the inside of the slot 3.

[0036] When the rib 62 completely enters the inside of the slot 3, the user will feel a certain resistance because at this time the rib 62 has contacted the plug board 81 of the limiting component 8. At this time, the user needs to apply a little more force to continue pushing the lens cover 6 deeper into the slot 3, so that the rib 62 presses the plug board 81 and makes the plug board 81 slide in the through groove 7.

[0037] As the plug board 81 slides, the convex block 82 moves along the direction of the through groove 7 under the guidance of the guide rod 83. At this time, the return spring 85 is compressed to provide an outward elastic force for the convex block 82 and the plug board 81. When the rib 62 completely passes through the plug board 81, due to the elastic force of the return spring 85, the plug board 81 will quickly reset, and the part of the plug board 81 that enters the slot 3 will immediately contact the side of the rib 62, thus realizing the limitation of the rib 62 and ensuring that the lens cover 6 is stably fixed in the slot 3.

[0038] In addition, the sealing rubber ring 61 forms a sealed environment between the lens cover 6 and the slot 3, effectively preventing dust and moisture from entering the interior of the LED light source structure and protecting the internal components from contamination and damage.

[0039] Through the synergistic effect of the metal plate 51, the thermal conductive adhesive layer 52, the heat conducting plate 53 and the heat dissipating plate 54, the heat dissipation component 5 conducts and dissipates heat quickly and evenly. The fan 55 further enhances the heat dissipation effect of the heat dissipating plate 54 by generating an air flow, prolonging the service life of the LED light source while maintaining its optical performance and color uniformity.

[0040] When the lens cover 6 needs to be disassembled, the user only needs to gently pull the insertion plate 81 outwards to separate the convex strip 62 from the insertion plate 81, and then the lens cover 6 can be taken out from the slot 3. The whole installation and disassembly process is simple and fast, without the need to use any tools, greatly improving the usability and maintainability of the LED light source packaging structure.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
