Thus, the illumination module can increase the area of the receiving space to provide more light-emitting elements, thereby improving the utilization rate of the light-emitting surface of the illumination module, and improving the illumination brightness and light-emitting efficiency when the power of the illumination module is the same. In addition, since there is no need to provide a pressing frame, a buckle, or a screw on the edge of the light-transmitting component, the illumination module can also reduce the defective rate of the product, save the installation steps, improve the installation efficiency, and reduce the cost.

[0011] For example, in the lighting module provided in an embodiment of the present disclosure, the side wall of the light-transmitting component includes: a first side wall, which is arranged opposite and spaced apart from the side wall of the base, and has a first gap between it and the side wall of the base; and a second side wall, which is arranged opposite and spaced apart from the side wall of the base, and has a second gap between it and the side wall of the base, the first side wall is located on the side of the second side wall away from the base, the second gap is larger than the first gap, and the sealing ring is at least partially arranged between the second side wall and the side wall of the base and is in close contact with the second side wall and the side wall of the base respectively.

[0012] For example, in the lighting module provided in an embodiment of the present disclosure, the sealing ring includes a first sealing portion, the first sealing portion is arranged between the side wall of the light-transmitting component and the side wall of the base, and in the state where the sealing ring is not compressed, the first sealing portion includes: a first plane, which is configured to contact the second side wall; a first arc surface, which is arranged opposite to the first plane, protrudes towards the outside and is configured to contact the side wall of the base; and a first inclined surface, which is connected to the first arc surface and is located on the side of the first arc surface close to the base, and the plane where the first inclined surface is located forms an acute angle close to the first side wall with the plane where the first plane is located.

[0013] For example, in the lighting module provided in an embodiment of the present disclosure, the first arc surface is in close contact with the side wall of the base and is in a compressed state to form a contact surface. The first inclined surface is located between the first side wall and the bottom plate, and the orthographic projection of the first inclined surface on the bottom plate at least partially overlaps with the orthographic projection of the second interval on the bottom plate.

[0014] For example, in the lighting module provided in an embodiment of the present disclosure, the side wall of the base includes a recessed portion that recesses from the surface of the side wall of the base close to the side wall of the light-transmitting component and is configured to accommodate a part of the sealing ring.

[0015] For example, in the lighting module provided in an embodiment of the present disclosure, the sealing ring further includes a second sealing portion that is disposed between the light-transmitting component and the bottom plate and is connected to the first sealing portion.

[0016] For example, the lighting module provided in an embodiment of the present disclosure further includes a circuit board located in the accommodating space, and at least one light-emitting element disposed on the circuit board and configured to emit light toward the light-transmitting component.

[0018] For example, in the lighting module provided in an embodiment of the present disclosure, the side wall of the light-transmitting component further includes a third side wall that is disposed opposite and spaced apart from the side wall of the base and has a third interval therebetween. The third side wall is located on the side of the second side wall close to the bottom plate, and the third interval is smaller than the second interval. The first side wall, the second side wall, and the third side wall form a recessed portion that recesses toward the center of the light-transmitting component, and the sealing ring is located in the recessed portion.

[0019] For example, in the lighting module provided in an embodiment of the present disclosure, the side wall of the light-transmitting component includes a fourth side wall located on the side of the first side wall away from the bottom plate, and the side wall of the base includes a fifth side wall.

[0026] For example, in the lighting module provided by an embodiment of the present disclosure, no screws are provided in the light-transmitting component, the base, and the accommodating space.

[0027] At least one embodiment of the present disclosure further provides a lighting device, including the lighting module described in any one of the above.

[0028] At least one embodiment of the present disclosure further provides an assembling method of a lighting module, which includes: sleeving the sealing ring on the outer side of the side wall of the light-transmitting component; positioning the base and the light-transmitting component; and applying a force to the light-transmitting component towards the base so that the sealing ring is disposed between the side wall of the light-transmitting component and the side wall of the base to seal the interval between the side wall of the light-transmitting component and the side wall of the base.

[0029] For example, in the assembly method provided by an embodiment of the present disclosure, when the lens sidewall includes a fourth sidewall located on a side of the first sidewall away from the second sidewall, the base sidewall includes a fifth sidewall, the fourth sidewall and the fifth sidewall are relatively spaced apart and have a fourth spacing, the fourth spacing is greater than the first spacing, and the fourth spacing is in communication with the first spacing and the second spacing, the assembly method further includes: disposing a sealant in the fourth spacing to seal the first spacing and the second spacing.

[0062] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are some, but not all, of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0063] Unless otherwise defined, technical terms or scientific terms used in this disclosure shall have the ordinary meanings as understood by those of ordinary skill in the art to which this disclosure pertains. The "first", "second" and similar terms used in this disclosure do not denote any order, quantity or importance, but are merely used to distinguish different components. Words such as "comprising" or "including" mean that the elements or items appearing before the word cover the elements or items listed after the word and their equivalents, without excluding other elements or items. Words such as "connected" or "coupled" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0064] The lighting module includes a base, a light-emitting element, a lens assembly and a heat sink; the base and the heat sink are integrated and form an accommodation space with the lens assembly, and the light-emitting element is disposed in the accommodation space. Generally, grooves are provided at the edges of both the base of the lighting module and the lens assembly. By providing a sealing ring in the groove, and then applying a pressure towards the base to the lens through a lens pressing frame or a buckle to compress the sealing ring in the glue groove, the above-mentioned accommodation space can be sealed, and the sealing ring is subjected to a positive extrusion pressure. In addition, a sealing glue can also be applied to the edges of the base and the lens assembly to enhance the sealing effect. By sealing the above-mentioned accommodation space, the light-emitting element can be prevented from being corroded by external water and oxygen, thereby improving the service life of the lighting module.

[0065] However, the lens pressing frame or the buckle will occupy a part of the area of the lens assembly, resulting in a reduced proportion of the light-emitting surface area of the lens assembly, and at the same time reducing the area of the accommodation space, thereby reducing the number of light-emitting elements per unit area and the light-transmitting area of the light-transmitting component, and further reducing the light-emitting efficiency.

[0066] In this regard, embodiments of the present disclosure provide an illumination module, an assembling method thereof, and an illumination device. The illumination module includes a base, a light-transmitting component, and a sealing ring; the base includes a bottom plate and a base side wall disposed on the bottom plate, and the base side wall and the bottom plate enclose a receiving groove; the light-transmitting component is disposed in the receiving groove to form a receiving space between the light-transmitting component and the bottom plate, and the light-transmitting component includes a light-transmitting component side wall, and the light-transmitting component side wall is disposed opposite and spaced apart from the base side wall; the sealing ring is at least partially disposed between the light-transmitting component side wall and the base side wall, and is in close contact with the light-transmitting component side wall and the base side wall respectively to seal the receiving space. Thus, the illumination module can seal the receiving space through the base side wall, the light-transmitting component side wall, and the sealing ring, without providing a pressing frame, a buckle, or a screw on the edge of the light-transmitting component. When the outer dimensions of the illumination module are the same (the outer dimensions here do not include the structure for external connection of the illumination module), the illumination module can increase the area of the receiving space to provide more light-emitting elements, thereby improving the utilization rate of the light-emitting surface of the illumination module, and improving the illumination brightness and light-emitting efficiency when the power of the illumination module is the same. In addition, since there is no need to provide a pressing frame, a buckle, or a screw on the edge of the light-transmitting component, the illumination module can also reduce the defective rate of the product, save the installation steps, improve the installation efficiency, and reduce the cost.

[0067] Next, the illumination module, the assembling method thereof, and the illumination device provided by embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0068] Figure 1A FIG. is a schematic structural diagram of an illumination module according to an embodiment of the present disclosure; Figure 1B FIG. is a plan view of an illumination module according to an embodiment of the present disclosure; Figure 2A The illumination module provided by an embodiment of the present disclosure is in Figure 1A The partial enlarged schematic view of the AA area shown.

[0069] As shown in Figure 1A , 1B and Figure 2AAs shown, the lighting module includes a base 110, a light-transmitting component 120, and a sealing ring 130. The base 110 includes a bottom plate 112 and a base sidewall 114 provided on the bottom plate 112. The base sidewall 114 and the bottom plate 112 enclose a receiving groove 210. At least part of the light-transmitting component 120 is disposed in the receiving groove 210 to form an accommodating space 220 between the light-transmitting component 120 and the bottom plate 110. The light-transmitting component 120 includes a light-transmitting component sidewall 124, and the light-transmitting component sidewall 124 is disposed opposite and spaced apart from the base sidewall 114. The sealing ring 130 is at least partially disposed between the light-transmitting component sidewall 124 and the base sidewall 114 and is in close contact with the light-transmitting component sidewall 124 and the base sidewall 114 respectively to seal the accommodating space 220. It should be noted that the above-mentioned base sidewall and light-transmitting component sidewall are both structures with a certain thickness, rather than just two-dimensional surfaces. Similarly, various sidewalls in the following text are also structures with a certain thickness, rather than just two-dimensional surfaces.

[0070] In the lighting module provided by the embodiment of the present disclosure, a light-emitting element can be disposed in the accommodating space. The light-emitting element is used for emitting light, and sealing the accommodating space can prevent the light-emitting element from being corroded by external water and oxygen, thereby improving the service life of the lighting module. Since the sealing ring is disposed between the light-transmitting component sidewall and the base sidewall and is in close contact with the light-transmitting component sidewall and the base sidewall respectively, the lighting module can seal the accommodating space through the sealing ring, the light-transmitting component sidewall, and the base sidewall, that is, a side-sealing method is provided. At this time, the sealing ring is in a compressed state under the force perpendicular to the base sidewall, and no additional fixing structures such as a pressing frame, a buckle, or a screw need to be provided on the edge of the light-transmitting component. When the outer dimensions of the lighting module are the same, the lighting module can increase the area of the accommodating space to dispose more light-emitting elements (such as light-emitting diode lamp beads), thereby improving the utilization rate of the light-emitting surface of the lighting module and, when the power of the lighting module is the same, improving the lighting brightness and light-emitting efficiency. In addition, since no additional fixing structures such as a pressing frame, a buckle, or a screw need to be provided on the edge of the light-transmitting component, the lighting module can also reduce the defective rate of the product, save the installation steps, improve the installation efficiency, and reduce the cost. It should be noted that, compared with the case where the sealing ring is in a compressed state under the force perpendicular to the bottom plate, when the sealing ring is in a compressed state under the force perpendicular to the base sidewall, the size of the sealing ring in the direction perpendicular to the base sidewall is smaller, thereby further improving the utilization rate of the light-emitting surface of the lighting module and, when the power of the lighting module is the same, improving the lighting brightness and light-emitting efficiency.

[0071] A comparative analysis is carried out with specific embodiments. Figure 2B is a dimensional drawing of a lighting module; Figure 2C is a dimensional drawing of a lighting module provided by an embodiment of the present disclosure. Figure 2BThe sealing ring of the lighting module shown is disposed between the bottom plate of the base and the light-transmitting component, occupying a part of the area of the edge region of the light-transmitting component, and the area occupied by the sealing ring is relatively large. In contrast, in the lighting module provided by the embodiments of the present disclosure, the sealing ring is disposed between the side wall of the base and the side wall of the light-transmitting component, such that Figure 2B the area in the edge region of the light-transmitting component in the lighting module shown that was originally occupied by the sealing ring can be used to arrange light-emitting elements, greatly improving the utilization rate of the light-emitting surface of the lighting module. In addition, Figure 2B two screw slots are provided on the light-transmitting component in the lighting module shown, which also occupy a part of the area. The screw slots are reserved for space when fixing the circuit board with screws. The lighting module provided by the embodiments of the present disclosure does not need to use screws to fix the circuit board, and no screw slots need to be provided on the light-transmitting component, further improving the utilization rate of the light-emitting surface of the lighting module.

[0072] For example, as Figure 2B shown, the length and width of the outer dimensions (including the snap-on frame) of the lighting module are: 241.4 mm * 75.4 mm. The area on this lighting module where light-emitting elements can be arranged is 216.6 mm * 50.4 mm = 10917 mm 2 , and the two screw slots occupy an area of 90 mm 2 * 2 = 180 mm 2 , the wiring slot occupies an area of 460 mm 2 , so the effective area where light-emitting elements can be arranged is 10277 mm 2 , and 28 light-emitting elements can be arranged. As Figure 2C shown, the length and width of the outer dimensions (including the side wall of the base) of the lighting module provided by an embodiment of the present disclosure are: 236 mm * 74 mm. The area on this lighting module where light-emitting elements can be arranged is 222.9 mm * 60.9 mm = 13575 mm 2 , the wiring slot occupies an area of 460 mm 2 , so the effective area where light-emitting elements can be arranged is 13115 mm 2 , and 36 light-emitting elements can be arranged. The effective area where light-emitting elements can be arranged on the lighting module provided by the embodiments of the present disclosure is increased by about 28% compared with Figure 2B the effective area of the lighting module shown. The outer dimensions of the lighting module provided in this embodiment are slightly smaller than Figure 2B the outer dimensions of the lighting module provided, but it can arrange about 8 more light-emitting elements. Then, under the condition of the same outer dimensions of the lighting module, in theory, the embodiments of the present disclosure can arrange more than 8 light-emitting elements, further improving the utilization rate of the light-emitting surface of the lighting module.

[0073] Under the condition that the power of the lighting module, the transmission efficiency of the light-transmitting component, and the optoelectronic parameters of the light-emitting element are the same, taking the lighting module power of 40W and the light-emitting element being Lumileds' LUXEON 5050 as an example, when there are 28 light-emitting elements, the driving current is about 60mA; when there are 36 light-emitting elements, the driving current is about 47mA; Figure 2D is the relationship curve of the current of a single light-emitting element and the normalized luminous flux output, Figure 2E is the relationship curve of the voltage and current of a single light-emitting element ([[]] Figure 2D and Figure 2E both come from the product specification of Lumileds' LUXEON 5050). When the test current of the light-emitting element is 160mA, the luminous flux output of a single light-emitting element at this time is 650lm. In Figure 2D the 650lm is normalized and used as the value 1. According to the luminous efficiency calculation formula: luminous efficiency = luminous flux / power, the following comparative analysis is carried out.

[0074] According to Figure 2D , when the driving current is 60mA, the normalized luminous flux output of the light-emitting element is about 0.4, and the actual luminous flux is 650lm * 0.4 = 260lm. According to Figure 2E , when the current is 60mA, the voltage is about 22.3V. At this time, the luminous efficiency of the light-emitting element is: 260lm / (60mA * 22.3V) ≈ 194.32lm / W;

[0075] According to Figure 2D , when the driving current is 47mA, the normalized luminous flux output of the light-emitting element is about 0.34, and the actual luminous flux is 650lm * 0.34 = 221lm. According to Figure 2E , when the current is 47mA, the voltage is about 21.9V. At this time, the luminous efficiency of the light-emitting element is: 221lm / (47mA * 21.9V) ≈ 214.71lm / W;

[0076] Under the condition that the power of the lighting module, the transmission efficiency of the light-transmitting component, and the optoelectronic parameters of the light-emitting element are the same, the lighting module provided by an embodiment of the present disclosure compared with the lighting module shown in Figure 2B , its luminous efficiency can be increased by (214.71 - 194.32) / 194.32 ≈ 10.5%.

[0077] Figure 3A is an example diagram of the force analysis of a lighting module; Figure 3B is a schematic diagram of the force analysis of a lighting module provided by an embodiment of the present disclosure; Figure 3C is a schematic diagram of the force analysis of another lighting module provided by an embodiment of the present disclosure; Figure 3D is a schematic cross-sectional view of a lighting module;Figure 3E It is a schematic cross-sectional view of another lighting module; Figure 3F It is a schematic cross-sectional view of another lighting module provided by an embodiment of the present disclosure.

[0078] As Figure 3D and Figure 3E shown, the provided lighting module generally uses the tensile force of snaps or screws to fasten the light-transmitting component 120 to the base 110. The sealing ring is arranged between the light-transmitting component and the base. The snaps and screws are both arranged at non-continuous intervals on the edge of the light-transmitting component 120. The pressing force received by the light-transmitting component 120 is uneven, and the positive pressure received by the sealing ring is also uneven. Considering factors such as cost, process, elastic deformation of the snaps, and interference between screws, the snaps and screws cannot be arranged densely; moreover, when fixing the snap-type light-transmitting component to the base, the maximum pressing force that the snap can withstand depends on the strength of the snap. The snap cannot be made very thick, otherwise it will affect its elastic deformation and cause the light-transmitting component to be unable to be installed; on the contrary, the snap cannot be made very thin, otherwise its strength is insufficient and it is easy to break, thus affecting the installation effect; when fixing the light-transmitting component with screws, the force of driving the screws cannot be too large, otherwise it is easy to damage the light-transmitting component. And even if the light-transmitting component does not break when the screws are driven, due to the torque existing after the screws are tightened, the light-transmitting component has a large internal stress, resulting in the light-transmitting component being easily damaged during use. In addition, when fixing the light-transmitting component with snaps or screws, the part of the light-transmitting component between adjacent snaps (or screws) is prone to arching (as Figure 3D and 3E shown by the dashed boxes). At the arching part, the positive pressure received by the sealing ring decreases, posing a potential risk of water seepage.

[0079] However, the lighting module provided by an embodiment of the present disclosure adopts a side sealing method. As Figure 3F shown, the sealing ring is sealed by the lateral extrusion force of the side wall of the light-transmitting component and the side wall of the base. The side walls of the light-transmitting component and the base are both continuous, so the extrusion force received by the sealing ring is uniform and continuous; and because the force acts in a mutual manner, the tension force received by the side wall of the light-transmitting component from the sealing ring is also uniform. In this way, on the one hand, it makes it easy to install the light-transmitting component on the base, and the side wall of the light-transmitting component will not break, which will not affect the installation effect; at the same time, the side wall of the light-transmitting component will not arch, avoiding the potential risk of water seepage; on the other hand, during use, the light-transmitting component will not come loose from the base, and it can be designed to withstand a greater tooling pressure than the snaps by increasing the thickness of the side wall of the light-transmitting component.

[0080] Next, taking the snap-type light-transmitting component as an example, a force analysis comparison is made between the conventional lighting module and the lighting module provided by an embodiment of the present disclosure.

[0081] As Figure 3AAs shown, the lighting module is provided with a buckle 129 at the edge of the light-transmitting component 120 for snap-fitting with the base 110. The sealing ring 130 is arranged between the light-transmitting component 120 and the base 110 and is fixed by pressing through the buckle 129, thereby realizing the fixation of the light-transmitting component 120 and the base 110. At this time, after the sealing ring 130 is subjected to the downward pressure F provided by the buckle 129 (the pressure in the direction from the light-transmitting component to the base), the base 110 will also generate an upward force F on the sealing ring 130.

[0082] As Figure 3B shown, the lighting module can be a lighting module provided by an embodiment of the present disclosure. As Figure 3B shown, when there is a draft angle, assuming that the component force F1 of the force of the base side wall 114 on the sealing ring 130 in the vertical direction is F, then the component force F2 of the force of the base side wall 114 on the sealing ring 130 in the horizontal direction is Fcotɑ, where ɑ is the draft angle (i.e., the included angle between F1 and F2). Generally, the draft angle is very small. When ɑ = 1°, F2 = 57.3F. At this time, the maximum static friction force f that can be generated by F2 is f = μF2. The friction coefficient of the sealing ring is about 0.8, so f = 45.8F. And the direction of the maximum static friction force f is opposite to the direction of the vertical component force F1. It can be seen from this that the lighting module provided by the embodiment of the present disclosure can provide a force of f - F1 = 44.8F to prevent the light-transmitting component from loosening in the case of a draft angle. The lighting module can ensure that the sealing ring and the light-transmitting component do not loosen without setting a pressing frame, a buckle or a screw on the edge of the light-transmitting component; moreover, the lateral pressure F2 provided by the lighting module provided by the embodiment of the present disclosure can reach 57.3F, thereby ensuring the waterproof performance.

[0083] As Figure 3C shown, the lighting module can be another lighting module provided by an embodiment of the present disclosure. As Figure 3C shown, when there is no draft angle, that is, when ɑ = 0, the vertical component force F1 of the force of the base side wall 114 on the sealing ring 130 is 0, and only the horizontal force F2 exists. At this time, the force to prevent the light-transmitting component from loosening is f. Since there is no vertical component force, theoretically, the lighting module can provide a greater lateral pressure and can more ensure that the sealing ring and the light-transmitting component do not loosen.

[0084] The above quantitative analysis is only for illustrating that the lighting module provided by the embodiments of the present disclosure can provide a greater pressure to compress the sealing ring. The process of the above analysis is only to draw a qualitative conclusion, and the actual force-bearing situation depends on the actual force-bearing requirements of the project. According to Hooke's law, the force in actual application depends on the compression amount of the sealing ring. The above analysis is only to illustrate that the structural design of the lighting module provided by the embodiments of the present disclosure can provide a greater force to the sealing ring, so that the sealing ring is subjected to a greater static friction force to prevent the light-transmitting component from loosening, and because the sealing ring is pressed tighter, the sealing effect of the lighting module will also be better.

[0085] For example, as Figure 1B shown, the side wall 114 of the base can be a surrounding wall structure around the bottom plate. Similarly, the side wall 124 of the light-transmitting component can also be a surrounding wall structure around the edge of the light-transmitting component 120. At this time, the sealing ring between the side wall 124 of the light-transmitting component and the side wall 114 of the base can be a corresponding annular structure.

[0086] For example, as Figure 1B shown, the shape of the orthographic projection of the side wall 114 of the base on the bottom plate can be a rounded rectangular ring, and the shape of the orthographic projection of the side wall 124 of the light-transmitting component on the bottom plate can be a rounded rectangular ring. Of course, the embodiments of the present disclosure include but are not limited to this. The shapes of the orthographic projections of the side wall of the base and the side wall of the light-transmitting component on the bottom plate can also be other annular structures as long as the accommodating space can be sealed.

[0087] In some examples, as Figure 1A 、 Figure 1B and Figure 2A shown, the light-transmitting component 120 can be a lens component, that is, including at least one lens portion 122. Of course, the embodiments of the present disclosure include but are not limited to this. The light-transmitting component 120 can also be other light-transmitting components.

[0088] In some examples, as Figure 1A 、 Figure 1B and Figure 2A shown, the side wall 124 of the light-transmitting component is configured to apply a force towards the side wall 114 of the base to the sealing ring 130, so that the sealing ring 130 is in a compressed state.

[0089] In some examples, the Shore hardness of the sealing ring is in the range of 25-40. The greater the Shore hardness of the sealing ring, the harder the sealing ring is, and the greater the force required to compress the sealing ring. The rebound force generated when the sealing ring is compressed is likely to lift up the light-transmitting component, thereby causing various defects. The smaller the Shore hardness of the sealing ring is, the softer the sealing ring is, and the larger the deformation of the sealing ring is, which is likely to lead to poor sealing effect. Therefore, the lighting module provided in this example can have a better sealing effect (for example, it can pass the waterproof test) by setting the Shore hardness of the sealing ring in the range of 25-40, and the sealing ring will not generate a large rebound force. In addition, when the Shore hardness of the sealing ring is in the range of 25-40, the life of the sealing ring is also improved.

[0090] For example, the Shore hardness range of the sealing ring is between 25-30, which can better balance the sealing effect and long service life.

[0091] In some examples, the compression rate of the sealing ring in the direction perpendicular to the side wall of the base ranges from 15% to 22%. At this time, the lighting module can have a good sealing effect (for example, it can pass the waterproof test), and the sealing ring will not generate a large rebound force. It should be noted that the lighting module provided in the embodiment of the present disclosure can pass the waterproof test, such as the IP68 waterproof grade test, when only the sealing ring is provided without the sealant.

[0092] In some examples, when the size of the second interval in the direction perpendicular to the side wall of the base is W, and the compression amount of the sealing ring in the direction perpendicular to the side wall of the base is σ, the compression rate calculation formula is:

[0093]

[0094] When the Shore hardness of the sealing ring ranges from 25 to 40 and the size of the second interval in the direction perpendicular to the side wall of the base ranges from 2.1 to 2.3 mm, waterproof tests are carried out by selecting different compression amounts (σ). For example, the compression amounts (σ) are 1 mm, 0.7 mm, 0.6 mm, 0.5 mm, and 0.4 mm respectively. According to the test results, when the compression amount (σ) is 1 mm, the rebound force generated after the sealing ring is compressed is relatively large, which will push up the edge of the light-transmitting component; when the compression amount (σ) is 0.7 mm, the rebound force generated after the sealing ring is compressed is still relatively large; when the compression amount (σ) is 0.6 mm, the sealing ring will not push up the edge of the light-transmitting component after being compressed, and passes the waterproof test; when the compression amount (σ) is 0.5 mm, the sealing ring will not push up the edge of the lens after being compressed, and passes the waterproof test; when the compression amount (σ) is 0.4 mm, the sealing ring will not push up the edge of the lens after being compressed, and passes the waterproof test; when the compression amount (σ) is less than 0.4 mm, the extrusion force on the sealing ring is insufficient and it fails the waterproof test. Therefore, it can be concluded that the range of the compression amount of the sealing ring in the direction perpendicular to the side wall of the base is 0.4 - 0.6 mm, and the range of the compression rate of the sealing ring in the direction perpendicular to the side wall of the base is 15% - 22%.

[0095] In some examples, such as Figure 1A , Figure 1B and Figure 2A shown, the lighting module further includes a sealant 160, and at least a part of the sealant 160 is located between the side wall 114 of the light-transmitting component and the side wall 124 of the base and on the side of the sealing ring 130 away from the bottom plate 112. For example, at least a part of the sealant 160 is located at one end of the interval between the side wall 114 of the light-transmitting component and the side wall 124 of the base, and this end is on the side of the sealing ring 130 away from the bottom plate 112. The sealing ring 130 can play a role in further sealing and can also play a role in fixing the light-transmitting component and the base.

[0096] In some examples, such as Figure 1A , Figure 1B and Figure 2A shown, the side wall 124 of the light-transmitting component includes a first side wall 1241 and a second side wall 1242; the first side wall 1241 is located on the side of the second side wall 1242 away from the base 110, that is, located at Figure 2AAbove the second side wall 1242 shown, the first side wall 1241 is spaced apart from the base side wall 114 at a relatively large distance, and there is a first gap 301 between the first side wall 1241 and the base side wall 114; the second side wall 1242 is spaced apart from the base side wall 114 at a relatively large distance, and there is a second gap 302 between the second side wall 1242 and the base side wall 114; the second gap 302 is larger than the first gap 301, and the sealing ring 130 is at least partially disposed between the second side wall 1242 and the base side wall 114 and is in close contact with the second side wall 1242 and the base side wall 114 respectively. Thus, the sealing ring is in close contact with the second side wall and the base side wall respectively, and the accommodating space can be sealed; and by providing the first side wall that is closer to the base side wall, the first side wall can be partially located above the sealing ring, so that the sealing ring can be prevented from jumping out during the installation and use of the lighting module.

[0097] In some examples, such as Figure 1A 、 Figure 1B and Figure 2A shown, the first side wall 1241 has a first side surface 141 on the side close to the sealing ring 130, and the first side surface 141 is connected to the second side wall 1242. The sealing ring 130 is in contact with the first side surface 141.

[0098] In some examples, such as Figure 1A 、 Figure 1B and Figure 2A shown, the surface of the first side wall 1241 close to the base side wall 114 and the surface of the second side wall 1242 close to the base side wall 114 are parallel. The first side surface 141 can be perpendicular to the surface of the second side wall 1242 close to the base side wall 114.

[0099] In some examples, such as Figure 1A 、 Figure 1B and Figure 2AAs shown, the sealing ring 130 includes a first sealing portion 132. The first sealing portion 132 is disposed between the side wall 124 of the light-transmitting component and the side wall 114 of the base. In a state where the sealing ring 130 is not compressed, the first sealing portion 132 includes a first flat surface 1322, a first arc surface 1323, and a first inclined surface 1324. The first flat surface 1322 is for contacting the second side wall 1242; the first arc surface 1323 is disposed opposite to the first flat surface 1322, protrudes outward and is configured to contact the side wall 114 of the base; the first inclined surface 1324 is connected to the first arc surface 1323 and is located on a side of the first arc surface 1323 close to the base 110. The plane where the first inclined surface 1324 is located forms an acute angle close to the first side wall 114 with the plane where the first flat surface 1322 is located. It should be noted that the above-mentioned first flat surface refers to a plane at least in the direction perpendicular to the bottom plate. When the shape of the orthographic projection of the sealing ring on the bottom plate is a rounded polygon ring (for example, a rounded rectangular ring), at the rounded corners, the surface of the first sealing portion in contact with the second side wall can be correspondingly changed according to the shape of the second side wall; for example, when the second side wall at the rounded corner is a curved surface, the surface of the first sealing portion in contact with the second side wall can also be a curved surface.

[0100] In the lighting module provided in this example, the first flat surface 1322 is for contacting the second side wall 1242, so that the sealing ring 130 can have a good contact with the second side wall 1242, enabling the sealing ring 130 to be stably sleeved on the light-transmitting component 120 and preventing the sealing ring 130 from being distorted. The first arc surface 1323 is disposed opposite to the first flat surface 1322 and is for contacting the side wall 114 of the base. The first arc surface 1323 has a certain guiding effect, so that the sealing ring 130 can be more smoothly pressed onto the side wall 114 of the base; the first inclined surface 1324 is connected to the first arc surface 1323. The plane where the first inclined surface 1324 is located forms an acute angle close to the first side wall 1241 with the plane where the first flat surface 1322 is located. On the one hand, the first inclined surface 1324 also has a certain guiding effect, which is convenient for installation. On the other hand, the first inclined surface 1324 can form a certain space with the bottom plate 112, so as to provide a reserved space when the sealing ring 130 is compressed. It should be noted that Figure 2A the sealing ring 130 in Figure 2A is in a compressed state, and the first arc surface can be referred to as shown by the dashed line in

[0101] In some examples, such as Figure 1A 、 Figure 1B and Figure 2AAs shown, the first arc surface 1323 is in close contact with the side wall 114 of the base and in a compressed state to form a contact surface. The first inclined surface 1324 is located between the first side wall 1241 and the bottom plate 112. The orthographic projection of the first inclined surface 1324 on the bottom plate 112 and the orthographic projection of the second interval 302 on the bottom plate 112 overlap at least partially. Thus, during installation, the first inclined surface 1324 can play a guiding role, making installation easier; moreover, a certain space is formed between the first inclined surface 1324 and the bottom plate 112, providing a reserved space when the sealing ring 130 is compressed. It should be noted that the size of the above-mentioned contact surface increases with the increase of the compression pressure of the sealing ring.

[0102] In some examples, such as Figure 1A 、 Figure 1B and Figure 2A As shown, the sealing ring 130 further includes a second sealing portion 134. The second sealing portion 134 is disposed between the light-transmitting component 120 and the bottom plate 112 and is connected to the first sealing portion 132. The first sealing portion 132 and the second sealing portion 134 are of an integral structure. Through the second sealing portion 134, the sealing ring 130 can better wrap around the light-transmitting component 120 and can prevent the sealing ring from being distorted when the light-transmitting component 120 and the sealing ring 130 are pressed down onto the base.

[0103] In some examples, such as Figure 1A 、 Figure 1B and Figure 2A As shown, the lighting module further includes: a circuit board 170 and at least one light-emitting element 190 disposed on the circuit board 170; both the circuit board 170 and the light-emitting element 190 are located in the accommodating space 220. Therefore, the circuit board 170 and the light-emitting element 190 can be protected from corrosion by external water and oxygen, thus having a longer service life and stability.

[0104] In some examples, such as Figure 1A 、 Figure 1B and Figure 2A As shown, when the light-transmitting component 120 is a lens component, at least one lens portion 122 and at least one light-emitting element 190 can be arranged in one-to-one correspondence. Each lens portion 122 can distribute light for the corresponding light-emitting element 190, thereby improving the light output effect of the lighting module.

[0105] In some examples, such as Figure 2AAs shown, there is a gap between the edge of the circuit board 170 close to the side wall 114 of the base and the side wall 114 of the base, and the second sealing portion 134 is provided between the edge of the circuit board 170 close to the side wall 114 of the base and the side wall 114 of the base. The second sealing portion 134 does not overlap with the circuit board 170, so that the light-transmitting component 120 can be closely attached to the circuit board 170. Thus, on the one hand, the light-transmitting component can play a role in fixing the circuit board, and on the other hand, it can also make the light-emitting elements on the circuit board closely fit with the lens portion, improving the light output effect. In some examples, as Figure 2A shown, the dimension of the second sealing portion 134 in the direction perpendicular to the bottom plate 112 is smaller than the dimension of the circuit board 170 in the direction perpendicular to the bottom plate 112 (i.e., the thickness of the circuit board).

[0106] In some examples, as Figure 1A 、 Figure 1B and Figure 2A shown, the lighting module further includes a heat sink 180; the heat sink 180 is disposed on the side of the bottom plate 112 away from the light-transmitting component 120, so as to dissipate heat for the light-emitting elements disposed in the accommodation space.

[0107] In some examples, as Figure 1A 、 Figure 1B and Figure 2A shown, the heat sink 180 and the base 110 can be an integral structure. That is to say, the heat sink is integrated on the surface of the base away from the light-transmitting component. At this time, the base can be made of a material with a relatively high thermal conductivity, such as metal, so as to improve the heat dissipation effect of the lamp housing. Of course, the embodiments of the present invention include but are not limited to this, and the base can also be made of other suitable materials.

[0108] In some examples, as Figure 1A 、 Figure 1B and Figure 2A shown, the heat sink 180 includes a plurality of heat dissipation fins 185 extending from the surface of the base 110 away from the light-transmitting component 120 in a direction away from the light-transmitting component 120, so as to have a better heat dissipation effect.

[0109] In some examples, in the natural state, the inner peripheral dimension of the sealing ring 130 is smaller than the outer peripheral dimension of the light-transmitting component 120, so that it can be firmly sleeved on the light-transmitting component. In addition, the inner peripheral dimension of the sealing ring being smaller than the outer peripheral dimension of the light-transmitting component can also prevent the sealing ring from jumping out. It should be noted that when the light-transmitting component includes the above-mentioned first side wall and second side wall, the outer peripheral dimension of the light-transmitting component can be the outer peripheral dimension of the first side wall. It should be noted that the above-mentioned natural state refers to the state where the sealing ring is not subjected to external force.

[0110] Figure 4 The lighting module provided according to an embodiment of the present disclosure is in Figure 1AAnother partial enlarged schematic view of the AA region shown. As Figure 4 shown, the side wall 124 of the light-transmitting component further includes a third side wall 1243; the third side wall 1243 is disposed opposite and spaced apart from the base side wall 114, and there is a third interval 303 between the third side wall 1243 and the base side wall 114. The third side wall 1243 is located on the side of the second side wall 1242 close to the bottom plate 112. The third interval 303 is smaller than the second interval 302. The first side wall 1241, the second side wall 1242, and the third side wall 1243 form a recessed portion 150 that is recessed toward the center of the light-transmitting component 120. The sealing ring 130 is located in the recessed portion 150. Thus, the sealing ring 130 can be better embedded in the recessed portion 150, avoiding the distortion and displacement of the sealing ring 130 during installation and use, thereby improving the sealing effect.

[0111] In some examples, as Figure 4 shown, the side of the third side wall 1243 close to the sealing ring 130 has a second side surface 142, and the second side surface 142 is connected to the second side wall 1242.

[0112] In some examples, as Figure 2A and Figure 4 shown, the side wall 124 of the light-transmitting component includes a fourth side wall 1244, which is located on the side of the first side wall 1241 away from the bottom plate 112. The base side wall 114 includes a fifth side wall 1145. The fourth side wall 1244 and the fifth side wall 1145 are disposed opposite and spaced apart, and there is a fourth interval 304 therebetween. The fourth interval 304 is larger than the first interval 301. The fourth interval 304, the first interval 301, and the second interval 302 are connected and communicated. The lighting module further includes a sealant 160, which is at least located in the fourth interval 304 to seal the first interval 301 and the second interval 302. Thus, the above-mentioned fourth interval 304 and the sealant 160 can further seal the accommodation space 220. In addition, since the size of the first interval is small, it is difficult to fill the sealant in the first interval. By setting the fourth interval larger than the first interval, the sealant can be better filled, facilitating the operation.

[0113] In some examples, as Figure 2A and Figure 4 shown, the dimension of the fourth interval 304 in the direction perpendicular to the base side wall 114 is much larger than the dimension of the first interval 301 in the direction perpendicular to the base side wall 114. For example, the dimension of the fourth interval 304 in the direction perpendicular to the base side wall 114 is more than 4 times the dimension of the first interval 301 in the direction perpendicular to the base side wall 114, so that the sealant can be better filled.

[0114] In some examples, as Figure 2A and Figure 4As shown, the orthographic projection of the first interval 301 on the bottom plate 112 falls within the orthographic projection of the fourth interval 304 on the bottom plate 112. That is to say, relative to the surface of the first side wall 1241 close to the base side wall 114, the surface of the fourth side wall 1244 close to the base side wall 114 is closer to the center of the lighting module; relative to the surface of the base side wall 114 opposite to the first side wall 1241, the surface of the fifth side wall 1145 close to the fourth side wall 1244 is farther from the center of the lighting module.

[0115] In some examples, as Figure 2A and Figure 4 shown, the sealant 160 can be located in the first interval 301 and the second interval 302 and contact the sealing ring 130. Of course, the embodiments of the present disclosure include but are not limited to this, and the sealant can also be located only in the fourth interval.

[0116] It should be noted that when the side wall of the light-transmitting component includes a third side wall, the cross-sectional shape of the sealing ring can be other shapes such as circular, horseshoe-shaped, etc., as long as it can achieve the sealing effect.

[0117] In some examples, as Figure 2A and Figure 4 shown, the bottom plate 112 includes a groove 1125, and the groove 1125 is located at the position of the bottom plate 112 close to the base side wall 114. The orthographic projection of the sealing ring 130 on the bottom plate 112 at least partially overlaps with the groove 1125. Thus, as Figure 2A shown, the groove 1125 can provide a reserved space for the expansion of the sealing ring, or, as Figure 4 shown, the groove 1125 can provide a reserved space for the third side wall 1243.

[0118] Figure 5A and Figure 5B is a partial enlarged schematic view of another lighting module provided by an embodiment of the present disclosure in the Figure 1A shown AA area. As Figure 5A and Figure 5B shown, the base side wall 114 includes a recess 1147, and the recess 117 is recessed from the surface of the base side wall 114 close to the side wall 124 of the light-transmitting component. The recess 117 can be used to accommodate the sealing ring 130, thereby further preventing the sealing ring 130 from coming out. For example, the recess 1147 and the second side wall 1242 can be oppositely arranged.

[0119] For example, as Figure 5A shown, the recess 1147 can be a square recess; as Figure 5B shown, the recess 1147 is an arc-shaped recess. For example, the recess 1147 can be located on the side of the fifth side wall 1145 close to the bottom plate 112.

[0120] Figure 6A partial enlarged schematic view of the lighting module provided according to an embodiment of the present disclosure in Figure 1A the BB area shown in. As Figure 1A and Figure 6 shown, the light-transmitting component 120 includes a first buckle 125 located at the center of the light-transmitting component 120, and the base 110 includes a second buckle 115 located at the center of the base 110. The first buckle 125 and the second buckle 115 cooperate with each other to connect to each other, so that the light-transmitting component 120 and the base 110 can be fixed. Thus, the lighting module can be fixed by the buckle structure; in addition, by arranging the buckle structure at the center of the light-transmitting component and the center of the base, the center of the light-transmitting component can be better prevented from arching. Of course, the lighting module provided by the embodiment of the present disclosure may not be provided with a buckle structure, so as to reduce the manufacturing difficulty of the light-transmitting component and the base and reduce the installation difficulty.

[0121] For example, the number of the first buckles 125 may be two, and the number of the second buckles 115 may also be two. Of course, the embodiments of the present disclosure include but are not limited to this. The number of the first buckles 125 may also be other numbers, and the number of the second buckles 115 may also be other numbers.

[0122] For example, both the first buckle 125 and the second buckle 115 are barb structures. During assembly, the barb structures of the first buckle 125 and the second buckle 115 are provided with inclined surfaces, so as to play a guiding role and make it easier to buckle.

[0123] Figure 7 A partial enlarged schematic view of the lighting module provided according to an embodiment of the present disclosure in Figure 1A the CC area shown in. As Figure 7 shown, the light-emitting element 190 can be arranged on the circuit board 170, and both the circuit board 170 and the light-emitting element 190 thereon are arranged in the accommodating space.

[0124] It should be noted that in the lighting module provided by the embodiment of the present disclosure, the circuit board and the base may be independent components; of course, the circuit board may also be integrated with the base, that is, a circuit structure is arranged on the bottom plate, and the light-emitting element is directly arranged on the bottom plate.

[0125] In some examples, as Figure 7 shown, the base 110 includes a positioning pin 117, and the circuit board 170 includes a positioning hole 177. The positioning hole 177 is configured to accommodate the positioning pin 117 and is arranged in cooperation with the positioning pin 117.

[0127] In some examples, since the circuit board 170 can be fixed by the light-transmitting component 120, screws are not provided in the light-transmitting component 120, the base 110, and the accommodating space 220, thereby reducing the installation difficulty and cost. In addition, since screws do not need to be provided, screw slots do not need to be reserved on the light-transmitting component 120, which can further improve the utilization rate of the light-emitting surface of the lighting module. Also, screw holes do not need to be machined on the lighting module, which can reduce the defective rate of the lighting module.

Since the lighting device adopts an integrated design, it is convenient for installation; when the lighting device is equipped with a plurality of lighting modules, the lighting device can place a plurality of lighting modules on the lamp housing at the same time and fix them uniformly, thereby simplifying the installation process and saving time and effort.

[0132] For example, as Figure 9As shown, the module buckle 230 includes an upper edge 2301, a lower edge 2302, and a side edge 2303 connecting the upper edge 2301 and the lower edge 2302; the upper edge 2301 is located on the side of the transparent cover plate 230 away from the bottom plate 112 and at the edge of the transparent cover plate 230, and the lower edge 2302 is located on the side of the extension wall 210 away from the transparent cover plate 230; the side edge 2303 connects the upper edge 2301 and the lower edge 2302, so that the upper edge 2301 and the lower edge 2302 can respectively apply pressure to the transparent cover plate 230 and the extension wall 210 to fix the transparent cover plate 220 on the extension arm 210.

[0133] For example, the lighting device may include a plurality of module buckles, which are spaced apart and arranged at the edge of the lighting device. Of course, the embodiments of the present disclosure include but are not limited to this. The lighting device may also include only one module buckle, which is arranged around the edge of the lighting device.

[0134] For example, the transparent cover plate 230 may be a glass substrate, a plastic substrate, or other transparent substrates. When the transparent cover plate 230 is a glass substrate, it can have both high strength and light transmittance, and can also play a self-cleaning role.

[0135] For example, an anti-glare pattern may be provided on the transparent cover plate 230 to prevent the occurrence of glare. For example, the anti-glare pattern may include silk printing.

The sealant filled in the groove 1842 can waterproof and seal the wire passing hole, and can also prevent the wires from being exposed and damaged.

[0138] Figure 11 FIG. is a schematic structural diagram of another lighting device provided according to an embodiment of the present disclosure. As Figure 11 shown, the lighting device 200 includes a plurality of lighting modules 100. The plurality of lighting modules 100 share the heat dissipation fins 182, and the plurality of lighting modules 100 are connected by the heat dissipation fins 182 to form a structure.

An embodiment of the present disclosure also provides an assembling method of a lighting module, and the lighting module can be the lighting module provided in any of the above examples. Figure 14 The flowchart of an assembling method of a lighting module provided according to an embodiment of the present disclosure. As Figure 14 shown, the assembling method of the lighting module includes the following steps S601-S603.

[0142] Step S601: Sleeving a sealing ring on the outer side of the side wall of the light-transmitting component.

[0143] Step S602: Positioning the base and the light-transmitting component.

[0144] Step S603: Applying a force to the light-transmitting component towards the base so that the sealing ring is arranged between the side wall of the light-transmitting component and the side wall of the base to seal the interval between the side wall of the light-transmitting component and the side wall of the base. It should be noted that although a force is applied to the light-transmitting component towards the base here, the force that makes the sealing ring in a compressed state is not the force applied to the light-transmitting component towards the base, but the force that is substantially perpendicular to the side wall of the base between the side wall of the light-transmitting component and the side wall of the base.

[0145] In the method for assembling the lighting module provided by the embodiments of the present disclosure, a flat tooling can be used to press the light-transmitting component from top to bottom, so as to apply a force towards the base to the light-transmitting component. During the process of pressing the light-transmitting component, the sealing rings around the light-transmitting component are extruded by the side wall of the base to generate a certain amount of compression, thereby achieving a sealing effect. Moreover, this assembling method has the advantages of simple steps, high assembling efficiency, and low cost.

[0146] In some examples, when the side wall of the lens includes a fourth side wall, which is located on the side of the first side wall away from the second side wall, the side wall of the base includes a fifth side wall, the fourth side wall and the fifth side wall are relatively and spaced apart, and there is a fourth interval, the fourth interval is greater than the first interval, and the fourth interval is connected to the first interval and the second interval, the assembling method further includes: arranging a sealant in the fourth interval to seal the first interval and the second interval, thereby achieving a double-sealing effect.

[0147] In some examples, before applying a force towards the base to the light-transmitting component so that the sealing ring is arranged between the side wall of the light-transmitting component and the side wall of the base to seal the interval between the side wall of the light-transmitting component and the side wall of the base, the assembling method can also heat the base (for example, the temperature is 160 - 170 degrees Celsius and the time is 4 - 5 minutes), so that the base has a certain expansion, thereby further reducing the assembling difficulty.

[0148] In some examples, when the lighting module includes a circuit board, the assembling method further includes fixing the circuit board through the positioning holes and the positioning pins on the bottom plate; when applying a force towards the base to the light-transmitting component so that the sealing ring is arranged between the side wall of the light-transmitting component and the side wall of the base to seal the interval between the side wall of the light-transmitting component and the side wall of the base, the lens component can press the circuit board against the base.

Therefore, screws are not provided in this lighting module, which can, on the one hand, reduce the assembly difficulty and improve the assembly efficiency, and on the other hand, reduce the cost. In addition, screws are not provided in this lighting module, and the assembly can be completed only by pressing, which is convenient for automated assembly.
