Description

Technical Field

[0001] The utility model relates to the technical field of lighting, in particular to a lamp. Background Art

[0002] Lamp fixtures utilize built-in high-precision lenses and reflector components to achieve precise light control at small angles, meeting a variety of complex lighting requirements. However, while pursuing efficient lighting effects, the assembly accuracy of the lens and lamp beads has become a key factor restricting the improvement of lamp performance.

[0003] Traditional lens fixing methods often rely on screws on the light source board. This method not only requires a large space on the light source board to accommodate the screws and the necessary creepage distance, but also limits the dense arrangement of the lamp beads, resulting in limited lighting effects and a larger overall lamp size. Furthermore, screw fixing also poses problems such as large assembly errors and inconvenient disassembly and maintenance, further affecting the product's market competitiveness and user experience.

[0034] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] It should be noted here that in order to avoid obscuring the present invention due to unnecessary details, only the structures and / or processing steps closely related to the scheme of the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0036] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0037] See also Figures 1 to 7 As shown, an embodiment of the present invention provides a lamp 200, comprising a housing 110, an optical assembly 100 and a power supply 120 housed in the housing 110. The power supply 120 is used to supply power to the optical assembly 100.

[0038] The length direction is the length extension direction of the housing 110. Figure 1 The x-axis direction is shown. The height direction is the height extension direction of the housing 110, as shown in FIG. Figure 1 In the z-axis direction shown, the length direction is perpendicular to the height direction. The housing 110 includes an end cap 1103, a side wall 1101 extending in the length direction, and a top wall 1104 disposed above the side wall 1101. The top wall 1104 and the side wall 1101 enclose a receiving cavity 1105 extending in the length direction. Two end caps 1103 are respectively disposed at both ends of the housing 110 to seal the receiving cavity 1105. The side of the receiving cavity 1105 away from the power supply 120 is a light outlet (not shown), and light emitted by the optical component 100 is emitted from the light outlet.

[0039] In some embodiments, a snap-fit ​​edge 1102 extending along the length direction is provided on the side wall 1101 of the housing 110 , and the snap-fit ​​edge 1102 is used for snap-fitting with the optical assembly 100 .

[0040] In some other embodiments, the sidewall 1101 of the housing 110 is provided with a plurality of snap-fit ​​edges 1102 extending along the length direction on the same horizontal plane, and the plurality of snap-fit ​​edges 1102 are used for snapping with the optical assembly 100 .

[0041] In some embodiments, a partition is provided in the accommodating chamber 1105 to divide the accommodating chamber 1105 into two upper and lower chambers. The optical assembly 100 and the power supply 120 are respectively installed in different chambers.

[0042] See also Figure 2 As shown, the optical assembly 100 includes a light source board 1, a lens 2, and a reflector 3 arranged in sequence along the height direction. Light emitted by the light source board 1 passes through the lens 2 and the reflector 3 in sequence and then is emitted from the light outlet.

[0043] See also Figures 2 to 4 As shown, the light source board 1 is fixed to the side of the accommodating cavity 1105 facing away from the power supply 120. The light source board 1 includes a substrate 11, a plurality of light-emitting components 12 disposed on the substrate 11, and a first positioning portion 13. The light-emitting components 12 are generally LED lamp beads. The first positioning portion 13 is used to securely connect 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 post.

[0044] The lens 2 is disposed below the light source board 1 and includes a lens substrate 21, a plurality of relief portions 211 disposed on the lens substrate 21, a light-transmitting structure 22, and a support column 213. The light-transmitting structure 22 is arranged on the lens substrate 21 along its length and extends from the lens substrate 21 toward the light source board 1. The light-transmitting structure 22 is disposed in a one-to-one correspondence 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 relief portions 211 are disposed at the edge of the lens substrate 21, cleverly utilizing the gap between the lens substrate 21 and the housing 110 to achieve a compact structure and thereby reduce the volume of the housing 110.

[0045] In some embodiments, the lens substrate 21 is further provided with a first engaging structure 212. The first engaging structure 212 is a hook. The first engaging structure 212 is disposed at an edge of the lens substrate 21 and extends from the lens substrate 21 toward the light source board 1. The first engaging structure 212 engages with the engaging edge 1102 to secure the lens 2 to the housing 110.

[0046] One end of the support column 213 abuts against the lens substrate 21, and the other end abuts against the substrate 11. The support column 213 provides additional support between the lens substrate 21 and the substrate 11, thereby improving the mechanical strength of the structure.

[0047] During the process of engaging the first engaging structure 212 with the engaging edge 1102, it is necessary to overcome certain resistance or to account for possible assembly errors, which may subject the first engaging structure 212 to significant stress. The support column 213 is positioned close to the first engaging structure 212, effectively sharing some of the stress and reducing direct impact on the first engaging structure 212, thereby protecting it from damage or deformation.

[0048] To securely connect the light source board 1 and the lens 2, a plurality of second positioning portions 23 are provided on the lens substrate 21. The second positioning portions 23 correspond to the first positioning portions 13, and the second positioning portions 23 engage with the first positioning portions 13 to achieve precise positioning and connection between the light source board 1 and the lens 2.

[0049] In this embodiment, the second positioning portion 23 is a positioning post. In other embodiments, the second positioning portion 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 to the substrate 11. Since the positioning post is non-metallic, it does not conduct electricity. Therefore, no creepage distance is required on the substrate 11, which reduces the required installation space and can accommodate small lamps.

[0050] See also Figure 5 As shown, in some preferred embodiments, a positioning post is disposed on the lens substrate 21 and extends from the lens substrate 21 toward the light source board. A through hole 231 is provided on the positioning post, extending through the positioning post and the lens substrate 21. Through hole 231 allows the operator to observe the position of the positioning hole and align the positioning post with the positioning hole, reducing installation difficulty and improving installation efficiency.

[0051] See also Figures 2 to 5 As shown, the positioning post includes a connecting end 232 and a positioning end 233 that are arranged opposite each other. The connecting end 232 is connected to the lens substrate 21, and the positioning end 233 is engaged with the positioning hole. The positioning end 233 includes a first column 2331 and a second column 2332 that are arranged concentrically. The diameter of the second column 2332 is smaller than that of the first column 2331. The diameter of the positioning hole is slightly larger than that of the second column 2332. The second column 2332 extends into the positioning hole, achieving an engaging connection between the positioning hole and the positioning post, thereby fixing the light source board 1 and the lens 2.

[0052] See also Figures 3 to 5 As shown, a step surface 2333 is provided between the first column 2331 and the second column 2332. The second column 2332 abuts against the substrate 11, and the diameter of the positioning column is smaller than that of the first column 2331, so that the first column 2331 is exposed in the positioning hole.

[0053] In some embodiments, in a direction perpendicular to the lens substrate 21, the light-transmitting structure 22 has a first height, and the positioning pillars have a second height. The light-transmitting structure 22 is a truncated cone-shaped structure that is smaller at the top and larger at the bottom. The first height is the distance between the top and bottom surfaces of the light-transmitting structure 22. The second height is the sum of the lengths of the first pillar 2331 and the second pillar 2332. The second height is greater than the first height, and the specific installation height of the lens can be determined by setting different second heights.

[0054] In some preferred embodiments, the height of the first column 2331, in a direction perpendicular to the lens substrate 21, is greater than the distance between the light-emitting element 12 and the lens substrate 21. This creates a mounting space between the substrate 11 and the light-transmitting structure 22, facilitating installation of the light-emitting element 12. Furthermore, the distance between the light-emitting element 12 and the light-transmitting structure 22 facilitates air circulation and reduces the operating temperature around the light-emitting element 12 and the light-transmitting structure 22.

[0055] The positioning post also includes a connecting wall 234, which connects the connecting end 232 and the positioning end 233. A wing 235 is provided on the connecting wall 234. The wing 235 extends from the connecting end 232 to the end of the first column 2331, abutting against the substrate 11. The wing 235 increases the contact area between the positioning post and the substrate 11, dissipating the pressure exerted by the positioning post on the substrate and enhancing the mechanical strength between the two, thereby improving structural stability.

[0056] See also Figures 2 to 6 As shown, the reflector 3 is disposed on the side of the lens 2 facing away from the light source panel 1. The reflector 3 includes a reflective substrate 31 and a plurality of reflective structures 32 disposed on the reflective substrate 31. The reflective structures 32 are arranged in a one-to-one correspondence with the light-transmitting structures 22. The reflective structures 32 form a reflective cavity. The reflective structures 32 are provided with a plurality of reflective ridges 321, each of which has a structure similar to a triangular pyramid. This arrangement increases the number and angle of light reflections on the reflective structures 32, thereby effectively concentrating the light reflection into the reflective structures 32, improving the reflection effect and light utilization.

[0057] The reflective substrate 31 is provided with a plurality of second engaging structures 33. These second engaging structures 33 are positioned corresponding to the relief portions 211, and their dimensions match those of the relief portions 211. The second engaging structures 33 pass through the relief portions 211 and engage with the engaging edges 1102 to secure the reflector 3 within the housing 110. In this embodiment, the relief portions 211 are recessed grooves formed on the reflective substrate 31 away from the second engaging structures 33.

[0058] In some embodiments, the size of the avoiding portion 211 is slightly larger than the second clamping structure 33 , so that the second clamping structure 33 can pass through the avoiding portion 211 easily.

[0059] The second clamping structure 33 is relatively long and easily deformed or bent during the clamping process. In some preferred embodiments, a reinforcing rib 331 (not shown) is provided on one side of the second clamping structure 33 near the reflective structure 32 to achieve more uniform stress distribution, effectively preventing the second clamping structure 33 from bending or breaking due to uneven or excessive force during the clamping process, and increasing the structural strength of the second clamping structure 33.

[0060] The reinforcing rib 331 includes a first end connected to the reflective substrate 31 and a second end away from the reflective substrate 31. The projected area of ​​the reinforcing rib 331 in a direction perpendicular to the reflective substrate 31 gradually decreases from the first end to the second end. This arrangement reduces the overall weight while maintaining sufficient strength.

[0061] Currently, on the market, two engaging edges 1102 extending along the length of the sidewall 1101 of the housing 110 are often provided. These two engaging edges 1102 are located at different heights. The second engaging structure 33 and the first engaging structure 212 engage with different engaging edges 1102, respectively, to secure the reflector 3 and the lens 2 to the housing 110. During the engagement process, the first engaging structure 212 first contacts the engaging edge 1102 engaged with the second engaging structure 33 before engaging with the corresponding engaging edge 1102, resulting in a jerky feeling. Furthermore, during engagement, it is difficult to determine whether the first engaging structure 212 is engaged with the correct engaging edge 1102.

[0062] See also Figures 2 to 7 As shown, in some preferred embodiments, the lens substrate 21 is provided with a first engaging structure 212 extending in the same direction as the second engaging structure 33. The first engaging structure 212 and the second engaging structure 33 are staggered, and both the second engaging structure 33 and the first engaging structure 212 engage with an engaging edge 1102 at the same height. This avoids a sense of jerkiness during the engaging process and prevents incorrect engaging with the engaging edge 1102.

[0063] In summary, the lens 2 of the present invention is clamped with the second positioning portion 23 and the first positioning portion 13 to complete the positioning clamping with the light source board 1, so as to achieve precise alignment between the light source board 1 and the lens 2. The light-emitting component 12 and the light-transmitting structure 22 are arranged in a one-to-one correspondence, ensuring that the light emitted by the light-emitting component 12 can be concentrated through the light-transmitting structure 22 to the maximum extent, thereby improving the utilization rate of the light. The lens 2 is provided with an avoidance portion 211, and the avoidance portion 211 matches the size of the second clamping structure 33, providing a precise guide and positioning reference for the installation of the reflector 3, ensuring that the second clamping structure 33 can be accurately aligned with its preset position during the installation process. After passing through its corresponding avoidance portion 211, the second clamping structure 33 is clamped with the housing 110, fixing the reflector 3 on the housing 110, preventing it from being displaced or loosened during operation, and achieving precise assembly of the reflector 3.

[0064] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention.
