[0040] Further, the light source assembly 110 comprises a lamp plate 111 and a lamp bead 112 (for example, an LED lamp bead) arranged on the lamp plate 111, the lamp plate 111 is connected with the driving module 120 through a wiring terminal and is connected to the chassis 100; the lens 200 is connected with the lamp plate 111 and covers the outside of the lamp bead 112 and is used for transmitting the light emitted by the lamp bead 112.
[0041] The connection mode of the lamp plate 111 with the chassis 100 comprises but is not limited to connection through fasteners such as bolts, clamping.
[0042] The assembly mode of the lampshade and the driving module 120 on the chassis 100 is similar to related technologies, and details are not repeated here. The driving module 120 is also connected with a terminal seat arranged on the chassis 100 and used for connecting a power supply such as a mains power supply.
[0043] In order to improve the safety of the lamp 010 and ensure the stability of the connection of the lamp plate 111 with the driving module 120 through the wiring terminal 121, the lamp 010 further comprises a terminal cover 130, the terminal cover 130 is connected with the lamp plate 111 and covers the outside of the wiring terminal 121 to shield the wiring terminal 121.
[0044] The connection mode of the terminal cover 130 with the lamp plate 111 comprises but is not limited to connection through fasteners such as bolts, clamping.
[0045] Of course, in other embodiments, the terminal cover 130 can also be connected with the chassis 100, which is not specifically limited here.
[0046] In order to shield and cover the non-light-emitting area on the lamp panel 111, reduce the exposure of the electrified part of the lamp panel 111, reduce the risk of electric shock, and improve safety. Please refer to Figure 2 、 Figure 3 and Figure 4 The lens 200 of the embodiment includes a light-transmitting part 210, a skirt 220, and a first convex rib 230. The light-transmitting part 210 is used to transmit the light emitted by the lamp bead 112. The skirt 220 is connected with the light-transmitting part 210 and is distributed around the outer periphery of the light-transmitting part 210. The skirt 220 has a first side 221 and a second side 222 distributed in opposite directions. The first convex rib 230 is connected with the skirt 220, and the first convex rib 230 is distributed at one end of the skirt 220 away from the light-transmitting part 210. Both the first convex rib 230 and the light-transmitting part 210 are protruded relative to the first side 221. Both the first convex rib 230 and the skirt 220 cover the non-light-emitting area of the lamp panel 111.
[0047] By covering the non-light-emitting area of the lamp panel 111 with the first convex rib 230 and the skirt 220, the problem of the exposure of other electrified parts on the lamp panel 111 where no lamp bead 112 is arranged can be improved, and the safety of the lamp 010 can be improved, and the problem of the risk of electric shock can be improved. Moreover, by arranging the first convex rib 230, the creepage distance can be increased, and the safety of electricity use can be further ensured.
[0048] Further, the lamp 010 includes at least two lenses 200, and the light source assembly 110 includes at least two lamp beads 112. The at least two lenses 200 are arranged in one-to-one correspondence with the at least two lamp beads 112. The first convex rib 230 of one lens 200 is distributed in a gap with the first convex rib 230 of another adjacent lens 200. By arranging a plurality of lenses 200, the non-light-emitting area on the lamp panel 111 can be covered as much as possible, and the problem of the exposure of other electrified parts on the lamp panel 111 can be improved, and the safety of the lamp 010 can be improved, and the problem of the risk of electric shock can be improved. Moreover, by arranging the lens 200 and the lamp bead 112 in one-to-one correspondence, different shapes and sizes of lamp panels (lamps) can be flexibly matched, and the cost of mold opening can be reduced.
[0049] Of course, in other embodiments, the first convex rib 230 of one lens 200 is in contact with the first convex rib 230 of another adjacent lens 200. In this way, the creepage requirement of the lamp 010 can be better met.
[0050] It should be noted that in the embodiment in which the first convex ribs 230 of the adjacent lenses 200 are distributed in a gap, the width of the gap should be set to be not more than the creepage distance requirement of the lamp 010, for example, the gap is less than or equal to 1 mm.
[0051] It should be noted that the first protruding ribs 230 and the skirt 220 are both covered on the non-light-emitting area of the lamp panel 111, which can mean that at least one of the first protruding ribs 230 and the skirt 220 is attached to the non-light-emitting area of the lamp panel 111, or at least one of the first protruding ribs 230 and the skirt 220 is distributed with a gap from the non-light-emitting area of the lamp panel 111.
[0052] Please refer to Figure 3 In this embodiment, the first protruding ribs 230 are distributed in a closed loop around the outer periphery of the skirt 220. In this way, on the one hand, the area of the entire lens 200 covered on the lamp panel 111 can be increased to improve safety; on the other hand, sufficient creepage distance can be ensured to further improve safety.
[0053] Further, the first protruding ribs 230 surround a square pattern; in this way, the entire lens 200 appears square in appearance, so as to form a more regular assembly structure when assembling multiple lenses 200 on the lamp panel 111, and to cover as much as possible the non-light-emitting area of the lamp panel 111 to improve safety.
[0054] Of course, in other embodiments, the first protruding ribs 230 can also surround a regular hexagon pattern.
[0055] Alternatively, in other embodiments, the first protruding ribs 230 can also surround an elliptical, circular, diamond, regular octagonal, etc. pattern.
[0056] Further, the height H of the first protruding ribs 230 is ≥ 3.5 mm, for example, 3.5 mm, 3.7 mm, 4.0 mm, etc., which is not limited here. In this way, the corresponding creepage distance requirement can be met to improve safety.
[0057] In order to achieve uniform and wide-angle light diffusion; please refer to Figure 3 , Figure 5 , Figure 6 and Figure 7 The light-transmitting portion 210 of the present embodiment has a light-emitting surface for emitting light, and the light-emitting surface includes a first circular-arc convex surface 211 and a second circular-arc convex surface 212 that are spliced together, the first circular-arc convex surface 211 surrounds the outer periphery of the second circular-arc convex surface 212, and the second circular-arc convex surface 212 surrounds a groove. In this way, the light-transmitting portion 210 forms a ring structure with a curved surface, and the light emitted from the lamp bead 112 is concentrated and refracted by the first circular-arc convex surface 211 and the second circular-arc convex surface 212, thereby increasing the angle of emission and improving uniformity.
[0058] Further, the curvature of the second arc convex surface 212 is smaller than the curvature of the first arc convex surface 211. In this way, the first arc convex surface 211 with a larger curvature can refract light rays at a larger angle, which is conducive to expanding the range of illumination.
[0059] Of course, in other embodiments, the curvature of the second arc convex surface 212 can also be equal to the curvature of the first arc convex surface 211.
[0060] Please refer to Figure 4 and Figure 7 The light-transmitting part 210 of the present embodiment also has a light-incident surface, which is provided with a receiving groove 213 for accommodating the lamp bead 112. In this way, the gap between the lens 200 and the lamp panel 111 can be reduced, which on the one hand reduces light leakage and on the other hand improves the reliability of the skirt 220 and the first convex rib 230 of the lens 200 covering and shielding the non-light-emitting area of the lamp panel 111, thereby improving the performance of electric shock prevention and ensuring safety.
[0061] Further, please refer to Figure 4 The second side 222 of the skirt 220 is connected with a second convex rib 240, which is connected with the lamp panel 111, for example, by bonding. The provision of the second convex rib 240 can support the lens 200, which is conducive to improving the problem of accidental compression of the lamp bead 112, i.e., to protect the lamp bead 112.
[0062] Of course, in other embodiments, the second convex rib 240 can also be connected with at least one of the first convex rib 230 and the light-incident surface of the light-transmitting part 210.
[0063] The number of second convex ribs 240 can be selected as needed. In the present embodiment, the second side 222 of the skirt 220 is connected with four second convex ribs 240, which are distributed at intervals around the outer periphery of the receiving groove 213. In this way, the stability of the lens 200 connected to the lamp panel 111 by the second convex rib 240 can be improved.
[0064] Of course, in other embodiments, the lens 200 and the lamp panel 111 can also be connected by fasteners such as bolts, or by clamping, etc., which are not specifically limited here.
[0065] In order to improve the production efficiency of the lens 200, the lens 200 of the present embodiment is integrally formed, i.e., the light-transmitting part 210, the skirt 220, the first convex rib 230, the second convex rib 240 and the receiving groove 213 are integrally formed.
[0066] Of course, in other embodiments, the connection of the various physical components of the lens 200 can also be connected by bonding or the like, for example: the skirt 220 can be bonded with the light-transmitting portion 210 or the like, which is not specifically limited here.
[0067] The lamp 010 of the embodiment emits light from the lamp beads 112 through the lens 200 and then through the lampshade when lighting.
[0068] In summary, the lens 200 of the utility model can be used for the lamp 010, and can improve the problem of exposure of other non-light-emitting charged parts on the lamp panel 111 without lamp beads 112, thereby improving the safety of the lamp 010 and solving the problem of easy electric shock danger.
[0069] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the utility model, which should be covered within the protection scope of the utility model.
