DETAILED DESCRIPTION
[0024] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be described in detail below in conjunction with the drawings and specific embodiments.
[0025] Here, it should be noted that in order to avoid the present application being obscured by unnecessary details, only the structures and / or processing steps closely related to the scheme of the present application are shown in the drawings, and other details not closely related to the present application are omitted.
[0026] In addition, it should also be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment.
[0027] Please refer to Figs. 1-7, the embodiment of the present application provides a lamp 200, which comprises a housing 110, and an optical assembly 100 and a power supply member 120 accommodated in the housing 110. The power supply member 120 is used to supply power to the optical assembly 100.
[0028] The length direction is the length extension direction of the shell 110, such as the x-axis direction shown in FIG. 1. The height direction is the height extension direction of the shell 110, such as the z-axis direction shown in FIG. 1, and the length direction is perpendicular to the height direction. The shell 110 includes end covers 1103, a side wall 1101 extending in the length direction, and a top wall 1104 arranged above the side wall 1101. The top wall 1104 and the side wall 1101 surround to form a containing cavity 1105 extending in the length direction. Two end covers 1103 are respectively arranged at two ends of the shell 110, for closing the containing cavity 1105. The containing cavity 1105 is away from the side of the power supply 120, and the light emitted by the optical assembly 100 is emitted from the light outlet (not shown).
[0029] In some embodiments, the side wall 1101 of the shell 110 is provided with a clamping rib 1102 extending in the length direction, and the clamping rib 1102 is used for clamping the optical assembly 100.
[0030] In other embodiments, the side wall 1101 of the shell 110 is provided with a plurality of clamping ribs 1102 extending in the length direction on the same horizontal plane, and the plurality of clamping ribs 1102 are used for clamping the optical assembly 100.
[0031] In some embodiments, the containing cavity 1105 is provided with a partition plate, which divides the containing cavity 1105 into two cavities. The optical assembly 100 and the power supply 120 are respectively arranged in different cavities.
[0032] Referring to FIG. 2, the optical assembly 100 includes a light source plate 1, a lens 2, and a reflector 3 arranged in sequence in the height direction. The light emitted by the light source plate 1 passes through the lens 2 and the reflector 3 in sequence and is emitted from the light outlet.
[0033] Referring to FIGS. 2 to 4, the light source plate 1 is fixed to the side of the containing cavity 1105 away from the power supply 120. The light source plate 1 includes a substrate 11 and a plurality of light emitting elements 12 and a first positioning portion 13 arranged on the substrate 11. The light emitting element 12 is generally an LED lamp bead. The first positioning portion 13 is used for fixedly connecting the lens 2. In this embodiment, the first positioning portion 13 is a positioning hole. In other embodiments, the first positioning portion 13 can also be a positioning column.
[0034] Lens 2 is disposed below light source plate 1. Lens 2 includes lens substrate 21, several clearance portions 211 disposed on lens substrate 21, light-transmitting structure 22, and support column 213. The light-transmitting structure 22 is arranged along the length of lens substrate 21 and extends from lens substrate 21 toward the light source plate 1. The light-transmitting structure 22 is disposed one-to-one with the light-emitting element 12, so that most of the light emitted by the light-emitting element 12 is processed by the light-transmitting structure 22. The clearance portions 211 are disposed at the edge of lens substrate 21, cleverly utilizing the gap space between lens substrate 21 and outer shell 110 to achieve a compact structure and thus reduce the volume of outer shell 110.
[0035] In some embodiments, the lens substrate 21 is further provided with a first snap-fit structure 212. The first snap-fit structure 212 is a hook. The first snap-fit structure 212 is disposed at the edge of the lens substrate 21 and extends from the lens substrate 21 toward the light source plate 1. The first snap-fit structure 212 snaps into the snap-fit edge 1102 to fix the lens 2 onto the housing 110.
[0036] One end of the support post 213 abuts against the lens substrate 21, and the other end abuts against the substrate 11. The support post 213 adds extra support between the lens substrate 21 and the substrate 11, improving the mechanical strength of the structure.
[0037] During the engagement of the first snap-fit structure 212 with the snap-fit edge 1102, it is necessary to overcome certain resistance or deal with possible assembly errors, and the first snap-fit structure 212 may be subjected to significant stress. The support column 213 is positioned close to the first snap-fit structure 212, which can effectively share some of the stress and reduce the direct impact on the first snap-fit structure 212, thereby protecting it from damage or deformation.
[0038] To fix the light source plate 1 and the lens 2 in place, a plurality of second positioning parts 23 are provided on the lens substrate 21. The second positioning parts 23 are correspondingly arranged with the first positioning parts 13, and the precise positioning and engagement of the light source plate 1 and the lens 2 are achieved by the second positioning parts 23 engaging with the first positioning parts 13.
[0039] In this embodiment, the second positioning part 23 is a positioning post. In other embodiments, the second positioning part 23 may also be a positioning hole. The positioning post is made of a non-metallic material, such as plastic or acrylic. The positioning post is fixed on the substrate 11. Since the positioning post is made of a non-metallic material, it is non-conductive. Therefore, there is no need to reserve a creepage distance on the substrate 11, which can reduce the required installation space and can be adapted to small lamps.
[0040] Please refer to FIG. 5, in some preferred embodiments, the positioning column is arranged on the lens substrate 21 and extends from the lens substrate 21 towards the direction close to the light source plate. The positioning column is provided with a through hole 231 penetrating the positioning column and the lens substrate 21. The operator observes the position of the positioning hole through the through hole 231 to align and install the positioning column with the positioning hole, which reduces the installation difficulty and improves the installation efficiency.
[0041] Please refer to FIGS. 2-5, the positioning column comprises a connecting end 232 and a positioning end 233 arranged oppositely, the connecting end 232 is connected with the lens substrate 21, and the positioning end 233 is clamped with the positioning hole. The positioning end 233 comprises a first column body 2331 and a second column body 2332 arranged concentrically, and the diameter of the second column body 2332 is smaller than that of the first column body 2331. The diameter of the positioning hole is slightly larger than that of the second column body 2332, the second column body 2332 extends into the positioning hole, and the clamping of the positioning hole and the positioning column is realized to fix and connect the light source plate 1 and the lens 2.
[0042] Please refer to FIGS. 3-5, a stepped surface 2333 is arranged between the first column body 2331 and the second column body 2332. The second column body 2332 is in abutment with the substrate 11, and the diameter of the positioning column is smaller than that of the first column body 2331, so that the first column body 2331 is exposed outside the positioning hole.
[0043] In some embodiments, in the direction perpendicular to the lens substrate 21, the light-transmitting structure 22 has a first height, and the positioning column has a second height. The light-transmitting structure 22 is a circular truncated cone structure with the top smaller and the bottom larger, and the first height is the distance between the top surface and the bottom surface of the light-transmitting structure 22. The second height is the sum of the lengths of the first column body 2331 and the second column body 2332. The second height is greater than the first height, and the specific installation height of the lens can be positioned by setting different second heights.
[0044] In some preferred embodiments, in the direction perpendicular to the lens substrate 21, the height of the first column body 2331 is greater than the distance between the light emitting element 12 and the lens substrate 21. An installation space is formed between the substrate 11 and the light-transmitting structure 22 to facilitate the installation of the light emitting element 12. In addition, there is a certain distance between the light emitting element 12 and the light-transmitting structure 22, which helps the air circulation and reduces the working temperature around the light emitting element 12 and the light-transmitting structure 22.
[0045] The positioning column further comprises a connecting wall 234 for connecting the connecting end 232 and the positioning end 233. The connecting wall 234 is provided with a wing part 235 extending from the connecting end 232 to the end of the first column body 2331 and in abutment with the substrate 11. The wing part 235 increases the abutment area of the positioning column with the substrate 11, disperses the pressure of the positioning column on the substrate, and also enhances the mechanical strength between the two, thereby improving the structural stability.
[0046] Please refer to FIG. 2 to FIG. 6, the reflector 3 is arranged on the side of the lens 2 away from the light source plate 1. The reflector 3 comprises a reflector substrate 31 and a plurality of reflecting structures 32 arranged on the reflector substrate 31. The reflecting structures 32 are arranged one by one corresponding to the light-transmitting structures 22. The reflecting structure 32 is a reflecting cavity. A plurality of reflecting edges 321 are arranged in the reflecting structure 32, and the reflecting edges 321 adopt an approximate three-prism structure. In this way, the reflecting edges 321 increase the reflection times and reflection angles of the light on the reflecting structure 32, thereby effectively concentrating and reflecting the light into the reflecting structure 32, and improving the reflection effect and the utilization rate of the light.
[0047] The reflector substrate 31 is provided with a plurality of second clamping structures 33, and the second clamping structures 33 are arranged corresponding to the avoiding portions 211, and the second clamping structures 33 and the avoiding portions 211 are dimensionally matched. The second clamping structures 33 pass through the avoiding portions 211 and are clamped with the clamping edges 1102 to fix the reflector 3 in the shell 110. In this embodiment, the avoiding portion 211 is a groove recessed in the direction away from the second clamping structure 33 of the reflector substrate 31.
[0048] In some embodiments, the size of the avoiding portion 211 is slightly larger than that of the second clamping structure 33, so as to facilitate the second clamping structure 33 to pass through the avoiding portion 211.
[0049] The length of the second clamping structure 33 is relatively long, and it is easy to be deformed or bent in the clamping process. In some preferred embodiments, the second clamping structure 33 is provided with a reinforcing rib 331 (not shown) on the side close to the reflecting structure 32, so that the stress distribution is more uniform, effectively preventing the second clamping structure 33 from being bent or broken due to uneven stress or excessive force in the clamping process, and increasing the structural strength of the second clamping structure 33.
[0050] The reinforcing rib 331 comprises a first end connected with the reflector substrate 31 and a second end away from the reflector substrate 31, and the projection area of the reinforcing rib 331 in the direction perpendicular to the reflector substrate 31 gradually decreases from the first end to the second end. In this way, the overall weight is reduced while maintaining sufficient strength.
[0051] At present, two clamping edges 1102 extending along the length direction are often arranged on the side wall 1101 of the shell 110, and the two clamping edges 1102 are at different heights. The second clamping structure 33 and the first clamping structure 212 are clamped with different clamping edges 1102 respectively, so as to fix the reflector 3 and the lens 2 on the shell 110 respectively. In the process of clamping the first clamping structure 212 with the clamping edge 1102, the clamping edge 1102 clamped with the second clamping structure 33 is first contacted, and then the corresponding clamping edge 1102 is clamped, so that a feeling of stagnation is generated. Moreover, it is difficult to judge whether the first clamping structure 212 is clamped into the correct clamping edge 1102.
[0052] Please refer to FIGS. 2 to 7, in some preferred embodiments, the first clamping structure 212 extending in the same direction with the second clamping structure 33 is arranged on the lens substrate 21. The first clamping structure 212 is arranged staggered with the second clamping structure 33, and the second clamping structure 33 and the first clamping structure 212 are clamped with the clamping edge 1102 at the same height, so that the feeling of stagnation is avoided in the clamping process, and the situation of clamping error with the clamping edge 1102 is also avoided.
[0053] In summary, the lens 2 is clamped through the second positioning part 23 and the first positioning part 13, the positioning and clamping with the light source plate 1 is completed, and the accurate alignment of the light source plate 1 and the lens 2 is realized. The light emitting part 12 is arranged one by one corresponding to the light transmission structure 22, so that the light emitted by the light emitting part 12 can be maximally condensed through the light transmission structure 22, and the utilization rate of the light is improved. The lens 2 is provided with the avoiding part 211, and the avoiding part 211 is matched in size with the second clamping structure 33, so as to provide accurate guidance and positioning reference for the installation of the reflector 3, and ensure that the second clamping structure 33 can be accurately aligned with the preset position in the installation process. The second clamping structure 33 is clamped with the shell 110 after passing through the corresponding avoiding part 211, so as to fix the reflector 3 on the shell 110, prevent displacement or loosening of the reflector 3 in the working process, and realize accurate assembly of the reflector 3.
[0054] The above embodiments are only used to illustrate the technical solutions of the present application but not limit the present application. Although the present application is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application.
