Description

Technical Field

[0001] This application belongs to the field of lighting device technology, and specifically relates to an LED potting lamp. Background Technology

[0002] LED potting lights are a type of lighting fixture manufactured using a potting process. Typically, epoxy resin, silicone, or other colloids are used to completely encapsulate and seal the LED and printed circuit board assembly (hereinafter referred to as the LED board) within the lamp housing. This process effectively improves the suitability of the lighting fixture in humid and dusty outdoor environments, giving it a high level of waterproof and dustproof performance, good heat dissipation, and excellent mechanical stability. These lights are particularly suitable for outdoor lighting applications such as roof lights, and can also be widely used in tunnel lighting, road lighting, and other similar applications.

[0003] In the prior art, an LED potting lamp includes a housing and an LED light board disposed inside the housing; the housing is provided with a potting port, and after the housing and the LED light board are assembled, potting compound is introduced into the housing through the potting port, and after curing, it completely covers the outside of the LED light board to achieve a sealing effect.

[0004] The inventors discovered that opening a potting port would damage the integrity of the lamp's appearance. Moreover, since the potting compound needs to completely cover the LED light board, its usage is difficult to control, which can easily lead to excessive use of potting compound. On the one hand, this results in technical defects such as prolonged curing time and reduced production efficiency. On the other hand, the potting compound is fluid when it is not fully cured, which can easily cause displacement of internal components, leading to functional failures of the lamp and reducing the yield of lamp production. Utility Model Content

[0005] This application provides an LED potting lamp that, while ensuring the integrity of the lamp housing, facilitates control over the amount of potting compound used, thereby shortening curing time, increasing lamp production efficiency, and ensuring the yield rate of lamp production.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: An LED potting light is provided, comprising: The outer casing has a structure with light emanating from the front and an open back, and a cover is provided on the back of the outer casing to close the open back. An LED light panel is disposed inside the housing, with its light emission direction facing the front of the housing; and A limiting plate is disposed inside the housing and located on the side of the LED light panel facing the opening of the housing; The limiting plate has a protrusion that abuts against the LED light panel to form a cavity between the limiting plate and the LED light panel. The limiting plate also has an observation hole that communicates with the adhesive cavity; When the outer casing is facing down and separated from the cover, colloid can be injected into the colloid cavity through the opening of the outer casing. Part of the colloid enters the observation hole, and the remaining part of the colloid covers the back of the LED light panel.

[0007] In one possible implementation, a guide post extending axially is fixedly disposed inside the housing, and a first through hole is provided on the LED light panel to allow the guide post to pass through.

[0008] In one possible implementation, the front of the housing has a reserved hole, a lens is embedded in the reserved hole, and a second through hole is provided on the lens to allow the guide post to pass through.

[0009] In one possible implementation, the inner wall of the housing has inwardly extending teeth, and the lens and the LED light panel are respectively provided with a first slot and a second slot; When the guide post is inserted into the first through hole and the second through hole, the retaining teeth are adapted to be embedded in the first retaining groove and the second retaining groove.

[0010] In one possible implementation, the limiting plate also has a third through hole extending through the protrusion along its thickness direction, the third through hole being used for the guide post to pass through.

[0011] In one possible implementation, the limiting plate has a plurality of force-dispersing protrusions on the side facing away from the LED light panel; Multiple force-dispersing protrusions are spaced apart circumferentially along the limiting plate, and each force-dispersing protrusion is adapted to abut against the inner side of the cover.

[0012] In one possible implementation, the inner side of the cover has a clamping ring; When the cover closes the housing, each of the force-dispersing protrusions abuts against the clamping ring, and the plurality of force-dispersing protrusions are arranged at intervals around the central axis of the clamping ring.

[0013] In one possible implementation, the housing has a support column extending toward the back; When the cover closes the housing, the extended end of the support post abuts against the inner side of the cover.

[0014] In one possible implementation, a slot is provided on the extended end face of the support column, and a plug suitable for insertion into the slot is fixedly provided on the inner side of the cover.

[0015] In one possible implementation, the limiting plate has pressure teeth; The pressure teeth have a sawtooth structure, with their ends extending into the adhesive cavity, and a wiring opening is formed between the pressure teeth and the LED light board for the circuit to pass through.

[0016] In this embodiment, there is no need for drilling on the outer surfaces of the outer shell and the cover, ensuring the appearance integrity of the lamp. On the other hand, the adhesive cavity provides space for the aggregation of the adhesive, and the aggregated adhesive block can effectively seal the LED light board. In this embodiment, unlike the technique of directly injecting adhesive into the inner cavity of the outer shell to fill it, this technique can reduce the amount of adhesive used, reduce the material cost of the lamp production, shorten the curing time, and improve the lamp production efficiency.

[0017] During the process of injecting adhesive into the cavity, the adhesive has a certain fluidity, so it can fill the cavity and fill the gap between the LED light board and the inner wall of the outer shell 1 (it will also fill the gap between the LED light board and the inner wall of the outer shell), thus completing the encapsulation and sealing of the LED light board.

[0018] Furthermore, the limiting plate abuts against the LED light panel via a protrusion located within the adhesive cavity, further reducing the amount of adhesive used. On the other hand, the contact between the protrusion and the LED light panel reduces movement of the LED light panel relative to the limiting plate, thereby preventing displacement of the LED light panel during the adhesive curing process.

[0019] Compared with the prior art, the LED potting lamp provided in this embodiment can eliminate the need to open holes for potting in the housing to ensure the integrity of the lamp's appearance; at the same time, it is also easier to control the amount of glue used, reduce material costs, shorten curing time, and avoid LED lamp board displacement, thus ensuring the yield of LED potting lamp production.

[0022] To make the technical problems, technical solutions, and beneficial effects to be solved by this application 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 are not intended to limit the scope of this application.

[0023] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0024] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0026] Please refer to the following: Figures 1 to 12 The LED potting lamp provided in this application will now be described.

[0027] First, it should be pointed out that the reason why existing LED potting lights have the problem of excessive glue usage during the potting and sealing process is that it is difficult for operators to directly observe the amount of glue inside the shell when injecting glue through the potting port. Typically, to ensure a good seal, operators inject glue until it overflows from the potting port, at which point the glue usage reaches its maximum, and the curing time increases exponentially. Furthermore, because uncured glue has a certain degree of fluidity, mechanical parts within the glue (such as the LED light board 2 in this application) will shift with the flow of the glue, causing technical defects such as a certain degree of misalignment between the LED light board 2 and the light-emitting area of ​​the shell 1. This leads to lighting malfunctions and reduces the yield rate of lamp production and processing.

[0028] To address the waterproofing issue of lighting fixtures through potting and sealing, while ensuring the integrity and consistency of their appearance, and simultaneously achieving the technical objectives of reducing adhesive usage, shortening adhesive curing time, and preventing component displacement due to adhesive flow, this application proposes an LED potting lamp. The proposed LED potting lamp includes a housing 1, an LED light board 2, and a limiting plate 3.

[0029] The outer casing 1 has a hollow internal structure, with a light-transmitting front and an open back. Based on this, a cover 11 is provided on the back of the outer casing 1. The cover 11 is detachably connected to the outer casing 1, and when connected, it can close the open end of the outer casing 1 to form a sealed cavity structure, achieving an external sealing effect and providing the first line of defense against water and dust for the internal components.

[0030] LED light board 2, also known as LED printed circuit board assembly or LED PCBA, refers to a complete functional module formed by assembling LED chips or LED beads as the core component and other necessary electronic components onto a PCB board. The LED light board 2 is located inside the housing 1; after entering the housing 1, the light-emitting part of the LED light board 2 faces the front of the housing 1, meaning that the LED light board 2 can project light onto the front of the housing 1 and emit it through the front of the housing 1, forming a beam of light that illuminates the environment.

[0031] Regarding the structural fit between housing 1 and LED light panel 2: (i) The outer peripheral wall of the LED light board 2 and the inner peripheral wall of the outer shell 1 are interference fit; during the glue injection, the glue is only applied to the side of the LED light board 2 facing the opening of the outer shell 1; (ii) There is a gap between the outer peripheral wall of the LED light board 2 and the inner peripheral wall of the outer shell 1, and the side of the LED light board 2 facing the front of the outer shell 1 is attached to the inner wall of the outer shell 1; during the injection of glue, the glue can fill the aforementioned gap; (iii) There is a gap between the outer peripheral wall of the LED light panel 2 and the inner peripheral wall of the outer shell 1, and there is a gap between the side of the LED light panel 2 facing the front of the outer shell 1 and the inner wall of the outer shell 1; the gap may be formed by the side of the LED light panel 2 facing the front of the outer shell 1 being a recessed structure, and / or the side of the outer shell 1 facing the LED light panel 2 being a recessed structure; during the injection of adhesive, the adhesive can flow from the outer edge of the LED light panel 2 and fill the gap, so that both the front and rear sides of the LED light panel 2 have cured adhesive.

[0032] The limiting plate 3 is disposed inside the housing 1 and is located on the side of the LED light panel 2 facing the opening of the housing 1. In this embodiment, the limiting plate 3 has an elliptical cross-section, which can enhance its inherent structural strength.

[0033] The limiting plate 3 has a protrusion 31 extending toward the front of the outer shell 1; after the outer shell 1, the LED light panel 2 and the limiting plate 3 are combined, the protrusion 31 abuts against the side of the LED light panel 2 facing the opening of the outer shell 1 to form a cavity 10 located between the limiting plate 3 and the LED light panel 2, inside the inner circumferential surface of the outer shell 1.

[0034] Furthermore, the limiting plate 3 also has an observation hole 32 communicating with the glue-containing cavity 10; in this embodiment, there are multiple observation holes 32, and the multiple observation holes 32 adopt an irregular opening design during processing. In this way, on the one hand, the limiting plate 3 reduces weight; on the other hand, multiple observation holes 32 can be observed simultaneously during the glue injection stage, so as to improve the accuracy of judging the height of the glue surface.

[0035] When the outer shell 1 is facing down and separated from the cover 11, the glue can be injected into the glue cavity 10 through the opening of the outer shell 1, and the glue will aggregate under the action of gravity, and the glue surface of the glue will gradually increase; when part of the glue enters the observation hole 32, the remaining part of the glue covers the back of the LED light panel 2 (the side with the LED light source is the front of the LED light panel 2, and the opposite side is the back of the LED light panel 2), at which point the glue injection can be stopped.

[0036] Regarding the structural fit between the outer shell 1 and the limiting plate 3: (a) The outer peripheral surface of the limiting plate 3 and the inner peripheral surface of the outer shell 1 have a gap to allow the adhesive to pass through, so as to realize the injection of adhesive into the adhesive cavity 10; (ii) The outer peripheral surface of the limiting plate 3 is in contact with the inner peripheral surface of the outer shell 1. At this time, in order to inject glue into the glue cavity 10, on the one hand, a hole close to the center of the limiting plate 3 can be opened, and on the other hand (when there are multiple observation holes 32), one of the observation holes 32 can be used for glue injection.

[0037] In this embodiment, neither the outer surface of the housing 1 nor the cover 11 requires drilling, ensuring the integrity of the lamp's appearance. Furthermore, the adhesive cavity 10 provides space for the aggregation of the adhesive, and the aggregated adhesive block effectively seals the LED light panel 2. This technique, unlike the method of directly injecting adhesive into the housing 1 to fill its inner cavity, reduces the amount of adhesive used, lowers the material cost of the lamp's production, shortens the curing time, and improves the lamp's manufacturing efficiency.

[0038] During the process of injecting adhesive into the cavity 10, the adhesive has a certain fluidity, so it can fill the cavity 10 and fill the gap between the LED light board 2 and the inner wall of the outer shell 1 (it will also fill the gap between the LED light board 2 and the inner wall of the outer shell 1), thus completing the potting and sealing of the LED light board 2.

[0039] Furthermore, the limiting plate 3 abuts against the LED light panel 2 via a protrusion 31, which is located within the adhesive cavity 10, thereby further reducing the amount of adhesive used. On the other hand, the contact between the protrusion 31 and the LED light panel 2 can reduce the movement of the LED light panel 2 relative to the limiting plate 3, thereby preventing the LED light panel 2 from shifting during the adhesive curing process.

[0040] Compared with the prior art, the LED potting lamp provided in this embodiment can eliminate the need to open holes for potting in the housing 1 to ensure the integrity of the lamp's appearance; at the same time, it is also easier to control the amount of glue used, reduce material costs, shorten curing time, and prevent the LED lamp board 2 from shifting, thus ensuring the yield of LED potting lamp production.

[0041] In some embodiments, such as Figure 8 and Figure 10As shown, a guide post 4 is fixedly installed inside the housing 1, extending along its axial direction (i.e., the orientation of the front and back of the housing 1), and a first through hole 21 is provided on the LED light panel 2 to allow the guide post 4 to pass through.

[0042] When assembling the housing 1 and the LED light board 2, the LED light board 2 needs to be fixed by a suction cup or other tools. Then, the LED light board 2 is inserted into the interior of the housing 1 through the opening, so that the guide post 4 is inserted into the first through hole 21 to restrict the movement of the LED light board 2 relative to the housing 1.

[0043] It should be noted that, in this embodiment, the guide post 4 has a protrusion extending radially outward, which is fixedly connected to the inner wall of the outer shell 1; on this basis, the first through hole 21 also penetrates the outer peripheral surface of the LED light panel 2 radially.

[0044] In some embodiments, such as Figure 5 , Figure 6 and Figure 8 As shown, the front of the outer casing 1 has a reserved hole 12 communicating with its interior, and a lens 5 is embedded in the reserved hole 12; specifically, the lens 5 is attached to the inner wall of the front of the outer casing 1 and has a spherical protrusion that passes through the reserved hole 12 and extends outward. Furthermore, the lens 5 can use the principle of refraction to change the light path, thereby achieving the technical purpose of controlling and shaping light.

[0045] To facilitate the combination of lens 5 and housing 1, lens 5 is provided with a second through hole 51 suitable for guide post 4 to pass through; that is, when the back of housing 1 is facing up, by placing lens 5 (through suction cup) inside housing 1 and inserting guide post 4 into the second through hole 51, and then moving lens 5 downward, lens 5 can be fixed in a preset position on housing 1, forming a semi-closed container (i.e., the front of housing 1 is closed and the back is open).

[0046] In some embodiments, such as Figures 5 to 8 As shown, the inner wall of the outer casing 1 has inwardly extending teeth 6, and the lens 5 and the LED light panel 2 are respectively provided with a first slot 52 and a second slot 22.

[0047] When the guide post 4 is inserted into the first through hole 21 and the second through hole 51, the locking tooth 6 is adapted to be embedded in the first locking groove 52 and the second locking groove 22. The locking tooth 6 and the first locking groove 52 and the locking tooth 6 and the second locking groove 22 are both interference fit, so as to simultaneously restrict the movement of the lens 5 and the LED light panel 2, and improve the stability and strength of the internal structure of the lamp.

[0048] In some embodiments, such as Figure 10 and Figure 11As shown, the limiting plate 3 also has a third through hole 33 that penetrates the protrusion 31 along its thickness direction. The third through hole 33 is used for the guide post 4 to pass through, and it is interference fit with the guide post 4 to ensure the tight fit effect of the limiting plate 3 after it is installed in the outer shell 1.

[0049] It should be noted that, in the direction from the front of the outer casing 1 to the back, as... Figure 10 As shown, the outer diameter of the guide post 4 changes to form a large diameter portion near the front of the housing 1 and a small diameter portion near the back of the housing 1; wherein, the large diameter portion can simultaneously cooperate with the first through hole 21 and the second through hole 51, while the small diameter portion only cooperates with the third through hole 33; when the small diameter portion is inserted into the third through hole 33 until the limiting plate 3 is installed in place (i.e., the protrusion 31 abuts against the LED light plate 2), the side of the limiting plate 3 facing the front of the housing 1 abuts against the coplanar surface of the large diameter portion and the small diameter portion.

[0050] In some embodiments, such as Figure 3 , Figure 9 and Figure 11 As shown, the limiting plate 3 has multiple force-dispersing protrusions 34 on the side facing away from the LED light panel 2.

[0051] Multiple force-dispersing protrusions 34 are spaced apart along the circumference of the limiting plate 3, and each force-dispersing protrusion 34 is adapted to abut against the inner side of the cover 11.

[0052] In this embodiment, the force-dispersing boss 34 can be, but is not limited to, a boss-shaped or rib-shaped structure. Its main function is to evenly distribute the clamping force provided by the cover 11 and prevent the limiting plate 3 from being damaged due to stress concentration. In some embodiments, the force-dispersing boss 34 can also be called a force-equalizing rib or a support rib.

[0053] In some embodiments, such as Figure 3 and Figure 11 As shown, the inner side of the cover 11 has a clamping ring 111.

[0054] When the cover 11 closes the outer shell 1, each force-dispersing protrusion 34 abuts against the clamping ring 111, and multiple force-dispersing protrusions 34 are arranged at intervals around the central axis of the clamping ring 111 to improve the uniformity of the clamping force distribution, thereby further ensuring the feasibility of the aforementioned beneficial effects.

[0055] In some embodiments, such as Figure 3 , Figure 4 and Figure 10 As shown, the housing 1 has a support column 13 extending toward its rear side.

[0056] When the cover 11 closes the outer shell 1, the extended end of the support column 13 abuts against the inner side of the cover 11, thereby supporting the cover 11 and preventing the cover 11 from moving excessively and causing damage to itself or the internal components of the outer shell 1.

[0057] In some embodiments, such as Figure 4 and Figure 5 As shown, a slot 131 is provided on the extended end face of the support column 13, and a rod 112 suitable for insertion into the slot 131 is fixedly provided on the inner side of the cover 11; when the rod 112 is inserted into the slot 131, the rod 112 and the slot 131 are interference-fitted to achieve a fixed combination of the cover 11 and the outer shell 1.

[0058] To enhance the strength of the connection between the insert 112 and the slot 131, the inside of the slot 131 can be filled with glue before the insert 112 is inserted.

[0059] By adopting the above-mentioned technologies, when assembling the outer shell 1 and the support column 13, the combination structure of the slot 131 and the plug 112 can avoid the cumbersome process and cost loss of fixing with screws in conventional products, simplify the production process and reduce production costs.

[0060] In some embodiments, such as Figure 3 and Figure 11 As shown, the limiting plate 3 has pressure teeth 35.

[0061] The pressure teeth 35 have a sawtooth structure, with their ends extending into the adhesive cavity 10, and a wiring opening is formed between the pressure teeth 35 and the LED light board 2 for the passage of lines (related to the LED light board 2 or used for power transmission).

[0062] By adopting the above technical solution, the wire pressing tooth 35 can achieve good wire pressing function and improve the tensile strength of the line, avoiding the problems of wire deformation and strength reduction caused by traditional planar wire pressing structure.

[0063] The above content is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
