[0041] For example, as used herein, the terms "horizontal", "vertical", "left", "right", "lateral", "longitudinal", "upper", "lower", and similar terms are used to describe the relative position of components in the present application and are not intended to limit the present application to any particular orientation.

[0042] Figure 1 An example of a low protection level LED module is shown, for example having a protection level of IP20. The LED module comprises a housing 1, a terminal 5 and a top package 6.

[0043] Figure 2 An example of a high protection level LED module is shown, for example having a protection level of IP67, which can comprise a housing 1, a package cover 2, a lead wire 3, and a seal such as a seal ring 4, etc.

[0044] The construction of the housing will be described below in connection with Figures 1-3C

[0045] The housing 1 is for example of a generally cuboid outer shape, inside which components of the LED module are arranged, for example electronic devices such as electrodes, control circuitry, etc. Figure 6A An example of the components of the LED chip is schematically described in the middle, which comprises various electronic components arranged on a PCB, the PCB board being connected at one end with a terminal 5, which can be connected with a lead wire 3, for realizing the electrical connection of the LED module with external components.

[0046] Figures 3A-3C An example of the specific construction of the housing 1 is shown. The housing 1 can comprise a main body 11, an extension portion 12, a positioning structure 13 inside the housing 1, lugs 14, and teeth 15, etc. The main body 11 constitutes an open-ended internal space, into which the LED components to be installed, for example a PCB board, etc., can be fed through the opening. The Figure 1 The top package 6 shown in the middle is for example installed on the opening to close the internal space into a sealed internal space. Alternatively, Figure 2 The end package structure of the present application shown in the middle, for example a package cover 2, can also be installed on the opening to close the internal space into a sealed internal space. ​

[0047] As shown in the accompanying drawings, Figure 3A The bottom surface of the main body 11 extends outward beyond the side walls of the housing 11 adjacent to the bottom surface, forming an extension 12. The extension 12 can include a flat surface against which the terminals 5 can be mounted. The extension 12 can be provided with a plurality of holes near its outer side end portion, and can also be provided with a plurality of notches at the edge of the outer side end portion. The holes and notches can assist in engaging the outer side extension 12 with the package cover 2, and / or assist in the positioning and securing of other components, such as the terminals 5.

[0048] Figure 3A An exemplary configuration of the interior of the main body 11 is also shown. One or more positioning structures 13 can be provided on the opposite inner side walls of the main body 11, respectively. Each positioning structure 13 includes a pair of tabs extending from the inner side wall of the main body 11 towards the interior of the main body 11, which can constitute a track configuration for a component of the LED module, such as a PCB board, to be inserted into and moved within. In the direction of the longitudinal axis of the main body 11 (i.e. the axis direction from the rear wall of the main body 11 to the opening direction), near the opening of the main body 11, one end of the two tabs are distanced from each other, and in the direction towards the rear wall of the main body 11, the spacing between the two tabs gradually decreases, forming a trumpet-shaped entrance of the track configuration, until at the rear side of the entrance, the two tabs become parallel to each other with a certain distance between them, thus forming a track. The track extends towards the rear wall of the main body 11. A component such as a PCB can be inserted into the track via the trumpet-shaped entrance, moved on the track, and positioned and secured within the interior space of the main body 11.

[0049] The number of positioning structures 13 can be two, which are arranged on the two opposite inner side walls of the main body 11, respectively. Alternatively, a plurality of positioning structures 13 with different sizes can also be employed. As shown in the arrangement, Figure 3A In the arrangement shown, four positioning structures 13 are provided. On the inner side wall of the main body 11, near the opening direction of the main body 11, a first positioning structure is provided, the entrance formed by the two tabs of which is relatively small, and the spacing between the parallel portions of the two tabs is also relatively small, forming a track with a small spacing. On the inner side wall of the main body 11, near the rear surface direction of the main body 11, a second positioning structure is provided, the entrance formed by the two tabs of which is relatively large, and the spacing between the parallel portions of the two tabs is also relatively large, forming a track with a large spacing. The above positioning structures of the present application can be formed integrally with the main body 11, for example, by using thermoplastic molding technology, etc. Alternatively, they can be formed separately from the main body 11.

[0050] According to the positioning structure of the present application, different sizes of components to be installed can be fixed flexibly, the installation of a variety of components can be realized, and the components to be installed can be stably fixed, thereby improving the reliability of the entire module.

[0051] Figure 3C The exemplary structure of the inner rear wall of the main body 11 is shown in the illustration. Multiple pairs of vertically opposed lugs 14 are provided on the rear wall of the main body 11, each pair including an upper lug and a lower lug. A space for accommodating a component to be installed is formed between the upper and lower lugs, and the two cooperate to clamp the component. The lugs of this invention can be integrally formed with the main body 11, for example, using thermoplastic molding or other techniques. Alternatively, they can be formed separately from the main body 11.

[0052] The rear sidewall of the outer casing 11 can also be marked with information about the casing material and internal components. The casing material can be common engineering plastics, such as PBT (polybutylene terephthalate), to achieve good mechanical properties, heat resistance, and chemical resistance. ABS (acrylonitrile-butadiene-styrene copolymer), PC (polycarbonate), etc., can also be used.

[0053] As attached Figure 3A and 3B As shown, the main body 11 of the housing 1 has a plurality of engaging components, such as teeth 15, at its opening portion and at the side edge opposite to the extension portion. The teeth 15 can engage with other components, such as corresponding engaging components, such as grooves, provided at the edge of the top package 6, to tightly engage the housing 1 with the top package 6.

[0054] Appendix Figure 1 The example shows terminal 5, which is electrically connected to a component within the body 11, such as a PCB board, to enable electrical connection between the LED component and external components.

[0055] The top package 6 can be combined with the housing 1 to form a sealed structure to encapsulate the components of the LED module within the internal space formed by the housing 1 and the top package 6.

[0056] The top package 6 includes a top cover 61 with a flat surface, which covers the opening of the body 11 to protect the devices disposed within the body, such as... Figure 1 As shown. The edge of the top cover 61 is provided with multiple grooves that engage with the teeth 15 to complete the encapsulation of the LED module. The top package 6 also has an opening 63 through which the terminals 5 protrude outward from the top cover 61.

[0057] The top package 6 also includes a surrounding structure 62 having an eaves-like construction, comprising sidewalls and a top wall connected to each other. The top wall is arranged generally parallel to the top cover 61, and the sidewalls extend forward along the sides of the body 11 from above the top cover 6 until they engage with the top wall. The surrounding structure 62 helps to protect the terminals 5 and components within the body 11.

[0058] Figure 2An example of a high protection level LED module is shown, which has, for example, an IP67 level of protection standard. The construction of the housing part and the like of this LED module is similar to the corresponding parts in Figure 1 , and therefore the same reference numerals are used to identify the same construction. This LED module includes a housing 1, a terminal 5 (not shown), and an end packaging structure such as a packaging cover 2.

[0059] The basic construction of the housing 1 can be similar to the housing construction shown in Figure 1 , which can include a main body 11, an extension part 12, a positioning structure 13, lugs 14 and teeth 15, and the like. Here, no further elaboration is made.

[0060] The packaging cover 2 can replace the top packaging 6 in Figure 1 to achieve the conversion of a low protection level LED packaging to a high protection level LED packaging. The packaging cover 2 is mounted on the housing 1 and tightly engages with the housing 1 through the engagement structure to achieve good waterproof and dustproof effect. The above-mentioned replacement can achieve the conversion of a low protection level LED module to a high level LED packaging module.

[0061] Figures 4A-4C An exemplary construction of the packaging cover 2 is shown. The packaging cover 2 can be constructed to engage with the housing 1 to form an overall packaging of the packaged LED module.

[0062] The packaging cover 2 can be a hollow shell structure with an opening, and the components of the LED module, such as the terminal 5, can be mounted in the hollow structure.

[0063] The packaging cover 2 can include a side edge engagement structure 21, a back side engagement structure 22 and a mesa 25. The mesa 25 includes a flat surface, and a platform surface side edge engagement structure 21 is provided at the edge of the flat surface. The side edge engagement mechanism 21 has an enclosing part surrounding the edge of the flat surface, and the cross section of the enclosing part is generally a concave shape, and the edge of the flat surface is enclosed in the notch part in the middle of the concave shape. The bottom of the enclosing part is provided with a step extending downward. The enclosing part includes a plurality of notch parts, at which the flat surface of the mesa 25 is not surrounded and extends uninterruptedly to the edge. The number of notch parts is set to correspond to the number of teeth 15 of the main body 11 of the housing 1. Through the notch part, the side edge engagement mechanism 21 can engage with the teeth 15 to firmly seal and fix between the packaging cover 2 and the housing 1.

[0064] A protrusion 24 is provided on the mesa 25, which protrudes outward from the mesa, and the height of the protrusion 24 is set to be higher than the terminal 5, and the inner space of the protrusion 24 is constructed to accommodate the terminal 5. The protrusion 24 can include two or more separate high platforms, and the Figure 4AAn example comprising two platforms is shown. Adjacent platforms are separated by recesses to accommodate two terminals respectively. The platforms are arranged separately from each other, thereby isolating the two terminals from each other. The number of platforms can also be other values, depending on the electronic components to be accommodated / isolated by the protrusions 24, such as the number of terminals.

[0065] A hole 23 is provided at the center of the top of the protrusion 24. The wire 3 can be inserted into the interior of the encapsulation cover 2 through this hole 23, thereby making an electrical connection with the terminal. The diameter of the hole 23 is set to be larger than the diameter of the wire 3, so that the area in the hole 24 not occupied by the wire 23 can be used as an injection hole for potting material. The diameter of the hole is set to 3 to 4 times the diameter of the wire, preferably 3.5 to 4 times. The diameter of the wire is, for example, 3 to 10 mm, such as 5 mm. The diameter of the hole can be, for example, 9 to 40 mm, such as 16.5 mm. The hole 23 is configured to allow the wire to pass through it for electrical connection, and at the same time, the hole 23 also serves as a material injection hole in the potting process, through which adhesive is injected to achieve encapsulation. The above-described structure of the hole 23 allows for potting and sealing after the encapsulation cover is installed, reducing the amount of adhesive used, shortening the potting process time, and simultaneously achieving a good seal.

[0066] A back-side engagement structure 22 is disposed near the edge of the raised back side of the protrusion 24, and can engage with the extension 12 of the housing 1 to assist in engaging the housing 1 with the package 2. The back-side engagement structure 22 may include multiple protrusions, attached... Figures 4A-4E The image exemplarily shows a plurality of first protrusions 221 and a plurality of second protrusions 222 spaced apart from each other, which respectively engage with holes and notches provided on the extension 12 of the housing 1 to join the extension to the encapsulation cover.

[0067] Step 26 is provided on the platform 25, adjacent to the side of the platform of the protrusion 24. A vertical surface 27 is provided above step 26.

[0068] Figure 4C The internal structure of the encapsulation cover 2 is illustrated in the figure. Inside the encapsulation cover 2, below the hole 23, on the back side of the plane containing the first protrusion 221 and the plurality of second protrusions 222, a plurality of fasteners 28 are provided. The fasteners may include protrusions that protrude inward, which can be used to assist in positioning and mounting components encapsulated in the housing 1 and the encapsulation 2, such as PCB boards.

[0069] The LED package module can further include a seal such as a seal ring 4. The seal ring 4 is installed above the hole 23 to seal the hole 23 to maintain the seal of the LED module. The seal ring 4 has a stepped structure that is snapped onto the hole 23 to seal the hole 23. One end of the lead wire 3 passes through the seal ring 4 and the hole 23 to connect to a terminal that is packaged in the housing. The lead wire 3 can be a flexible lead wire that is provided to be about 1 m in length, for example, 0.5 to 10 m.

[0070] Figures 5A-5C An example of the seal of the present application is shown. The example of the seal includes the seal ring 4. Figure 5A The relative sizes between the lead wire 3 and the hole 23 are shown, in this example, the seal ring 4 has not yet been installed. With the lead wire 3 inserted into the hole 23, there is a gap between the two, and the gap between the lead wire 3 and the seal ring 4 is filled with the encapsulation adhesive, thereby completing the adhesive injection. Figure 5B The state of the seal ring 4 to be installed after the adhesive injection is shown in the middle.

[0071] The seal ring 4 is made of a deformable material, for example, an elastic material such as silicone rubber, ethylene propylene diene rubber (EPDM), fluororubber, thermoplastic elastomer (TPE), etc.

[0072] The seal ring 4 has an internally hollow plug structure that includes a lead wire inlet 41 at the center of the top thereof, the lead wire inlet 41 being formed by two or more elastic films. When the lead wire 3 is not inserted, the elastic films abut against each other to block the lead wire inlet 41, so that the lead wire inlet 41 is in a non-exposed state. When the lead wire 3 is inserted into the lead wire inlet, the elastic films are deformed by the lead wire, thereby exposing the lead wire inlet 41. The seal ring 4 has a first protrusion 42 and a second protrusion 43. The first protrusion 42 is located above the second protrusion 43, and the first protrusion 42 and the second protrusion 43 are oppositely disposed.

[0073] The second protrusion 43 is arranged on the outer side of the lower part of the seal ring and extends upward from the seal ring. The maximum outer diameter of the second protrusion 43 is greater than the diameter of the hole 23, for example, 1.2-1.5 times the diameter of the hole 23. The first protrusion 42 is arranged on the outer side of the upper part of the seal ring and extends downward from the seal ring. The maximum outer diameter of the first protrusion 42 is greater than the maximum outer diameter of the second protrusion 43, for example, 1.3-1.8 times the diameter of the hole 23. When the seal ring is pressed downward to contact the plane of the housing 2 outside the hole 23, the second protrusion 43 is elastically deformed and pressed through the hole 23 to below the hole 23. When it is below the hole 23, the second protrusion 43 abuts against the bottom surface of the plane around the hole 23, pressing and fixing the lower part of the seal ring below the plane around the hole 23. At this time, the first protrusion 42 is also elastically deformed and abuts against the top surface of the plane around the hole 23 above the plane. At this time, the first protrusion 42 is above the hole 23 and clamped near the edge of the hole 23 on the outside of the housing 2, and the second protrusion 43 is below the hole 23 and clamped near the edge of the hole 23 on the inside of the housing 2. The first protrusion 42 exerts a downward force and the second protrusion 43 exerts an upward force, so that the seal ring 4 can be firmly fixed on the housing 2 and the housing 2 is sealed.

[0074] The process of installing the package cover 2 on the housing will be described below in conjunction with Figures 6A-6F

[0075] Figure 6A The PCB board on which the electronic circuit and the lead wire are mounted is shown in a state of being about to be installed in the housing 1. The PCB board is inserted into the groove formed by the slot structure 13 provided in the housing 1, pushed into the housing and positioned, and finally positioned via the lugs on the bottom of the housing. Figure 6B The state after the PCB is fixed in the housing 1 is shown.

[0076] After the PCB board is fixed in the housing, the cover 2 is installed on the housing 1 via its engaging structure, and the two are tightly engaged, Figure 6C The state after the cover 2 is installed on the housing 1 is shown. The lead wire 3 passes through the seal ring 4. Then the seal frame is installed at the top outer edge of the housing. The inner diameter of the seal frame is shaped to match the shape of the outer diameter of the housing 1, and the size of the inner diameter can be substantially equal to or slightly smaller than the inner diameter of the housing 1.

[0077] In Figure 6D , the potting agent for encapsulation, such as epoxy resin potting agent, silicone potting agent or polyurethane potting agent, or other potting agents with properties meeting the encapsulation requirements of the LED module, such as transparency, thermal conductivity, insulation, etc., is injected through the hole 23 by using a potting device, such as an injection device or a glue gun, etc.​

[0078] In the glue-filling process, the defoamed glue can be slowly and evenly injected into the packaging area of the LED module using a glue gun. Multiple glue-filling processes can be adopted, and after each glue-filling process, a certain period of time is waited for the glue to preliminarily solidify or flow flat, and then the next glue-filling process is performed, so as to form a good packaging effect.

[0079] After the glue-sealing process is completed, a solidification process is performed, and the filled glue can be solidified through a conventional solidification process, a thermal solidification process, etc.

[0080] After the solidification is completed, the sealing ring 4 is installed into the hole 23 to seal the LED packaging module, as shown in FIG. 4. Figure 6E After that, the sealing frame used in the glue-sealing process can be removed. The packaging of the LED module is completed.

[0081] According to the above structure of the utility model, the packaging cover 2 with the above structure can be used to package the LED module, and the glue-filling step is performed after the packaging cover 2 is installed. This makes it possible to package with a small amount of glue injection, shortens the time spent in the glue injection process, and reduces the glue injection cost.

[0085] Among them, the positioning structure in the housing can be used to insert and position the PCB in the housing along the track.

[0086] Step two: fix the PCB in the housing so that the terminals are exposed outside the opening of the housing.

[0087] Step three: use the end packaging structure to cover the terminals, and the end packaging structure is combined with the housing to form a sealed LED module.

[0088] Among them, the end packaging structure is the end packaging structure mentioned in the foregoing, which includes one or more of the protruding part, the side edge joint structure, the sealing member, the back side joint structure, etc.

[0089] Among them, at the side edge of the opening of the housing, the position where the housing is combined with the end packaging structure, a sealing frame is installed. The shape of the sealing frame is adapted to the shape of the edge of the housing 2, and the size of the sealing frame can be slightly smaller than the edge of the housing 2.

[0090] Step four: inject glue through the hole on the top of the end package structure to glue the LED module.

[0091] Step five: after the glue injection is completed, install the sealing ring of the end package structure on the hole on the top of the end package structure to seal the hole.
