Description

Technical Field

[0001] This utility model belongs to the technical field of LED lighting fixtures, specifically relating to a lamp body structure and lighting equipment. Background Technology

[0002] Linear lights are lighting fixtures that combine LED light sources with linear elements. Their housings are made of aluminum alloy or plastic, allowing for seamless installation on walls, ceilings, or cabinets for decorative lighting. Linear lights can be fixed to external mounting bases using surface mounting, pendant mounting, recessed mounting, or magnetic mounting methods. Their convenient and diverse installation options, coupled with their simple appearance and uniform light output, have earned them a significant market share.

[0003] Linear lights generally include a heat sink, a light source assembly, a light cover, and an end cap. Since linear lights have a linear or strip-shaped appearance, the light source board also adopts a similar contour design to the light body. In the prior art, the light source board is generally fixed in the heat sink in the following ways: (1) Screw fixing: The light source board is installed in the heat sink and fixed to the light body with screws. This installation structure is stable and reliable, but it requires opening holes in the light body, which increases the processing steps of the light body and the assembly steps of the whole lamp; in addition, the screw holes opened in the heat sink will affect the uniform arrangement of the light source and thus affect the light spot effect; at the same time, there is also a problem of sealing, which will affect the light spot effect. (2) Thermally conductive double-sided adhesive bonding: The light source board is pasted on the light body with thermally conductive double-sided adhesive. This installation structure simplifies the assembly, but increases the material cost; in addition, the bonding process is more complicated, and it is easy to produce uneven bonding surfaces and displacement of the light-emitting surface, resulting in poor light output effect, and the production efficiency of adhesive bonding is low. Utility Model Content

[0004] To address the shortcomings of the prior art, this utility model provides a lamp body structure in which the light source assembly is pushed into a receiving groove in the lamp body and limited by a boss, improving assembly efficiency.

[0049] Example 1

[0050] refer to Figures 1-5 This embodiment provides a lamp body structure 100, including a lamp body 1, a light source assembly 2, and a cover 3. The lamp body structure 100 serves as the main body of a linear or strip-shaped lamp, and has an overall strip-like structure. The lamp body 1, serving as the frame of the lamp body structure 100, can be made of stamped aluminum profile or integrally injection molded plastic. The lamp body 1 includes a base 11 and a pair of side portions 12, which are disposed opposite each other on both sides of the base 11 in the transverse direction X. The base 11 and the two side portions 12 extend in the longitudinal direction Y, and the base 11 and the side portions 12 surround to form a receiving cavity 13. After the light source assembly 2 is installed, the receiving cavity 13 serves as a light-emitting cavity for adjusting the light.

[0051] The side portion 12 includes a side plate 121, a protrusion 122, and a first connecting arm 123, while the base portion 11 has a base surface 110. The side plate 121 is disposed on both sides of the base portion 11 and is formed away from the base surface 110 in the height direction Z. The first connecting arm 123 is located at the end of the side plate 121 away from the base portion 11 (base surface 110). The protrusion 122 is disposed on the inner side of the side plate 121. It is understood that the protrusion 122 protrudes from the inner side of the side plate 121 toward the receiving cavity 13, and a receiving groove 131 is formed between the protrusion 122 and the base portion 11. As part of the receiving cavity 13, the receiving groove 131 is a groove structure formed by the base portion 11, part of the side plate 121, and the protrusion 122, and the receiving groove 131 communicates with the receiving cavity 13.

[0052] The light source assembly 2 is installed in the receiving groove 131. The light source assembly 2 includes a light source substrate 21 and a light-emitting element 22. The light source substrate 21 may be an aluminum substrate or a ceramic substrate. The light-emitting element 22 is an LED lamp bead attached to the light source substrate 21 and may be soldered into the light source substrate 21 using an SMD surface mount method. In some embodiments, the light-emitting element 22 may also be a COB light source.

[0053] The cover 3 includes a cover plate 31 and a second connecting arm 32. The cover plate 31 is a light-emitting plate with a light-amplifying function, and the second connecting arm 32 is disposed on the cover plate 31. The cover 3 is detachably mounted on the lamp body 1. The cover plate 31 covers the opening of the receiving cavity 13, and the second connecting arm 32 extends into the receiving cavity 13 and is engaged with the inner side of the first connecting arm 123. In some embodiments, the second connecting arm 32 is engaged with the first connecting arm 123.

[0054] It should be noted that the protrusion 122 is provided with a boss 124, which protrudes towards the base surface 110 in the height direction Z, and the boss 124 abuts against the light source substrate 21.

[0055] The light source assembly 2 is directly installed into the receiving groove 131 using a push-in installation method, without the need for other auxiliary tools. During installation, the light source substrate 21 is aligned with the receiving groove 131 and then pushed in along the longitudinal direction Y, i.e., the light source assembly 2 is inserted into the receiving groove 131. After the push-in (insertion) is completed, the bosses 124 of the base 11 and the protrusions 122 support and limit the light source assembly 2 in the height direction Z; the side plates 131 on both sides limit the light source assembly 2 in the transverse direction X; in addition, the end caps (not shown in the figure) at both ends of the lamp body 1 limit the light source assembly 2 in the longitudinal direction Y, thereby limiting the installation of the light source assembly 2 from all directions and ensuring its fixed position.

[0056] The cover 2 and the lamp body 1 are detachably connected together by the second connecting arm 32 and the first connecting arm 123. When it is necessary to remove the cover 3, the cover 3 can be pulled out along the longitudinal Y and height Z directions for maintenance and component replacement.

[0057] With reference to Figure 3 and Figure 4 , the light source substrate 21 is pushed into and installed in the accommodating groove 131. The light source substrate 21 is oppositely provided with a first mounting surface 211 and a second mounting surface 212 in the height direction, wherein the first mounting surface 211 is attached and connected to the base surface 110. The second mounting surface 212 is located on a side of the light source substrate 21 facing away from the base surface 110. The second mounting surface 212 comprises a light-emitting region 2121 and a mounting region 2122, the light-emitting region 2121 transversely extends across the middle part of the second mounting surface 212 along the longitudinal direction Y, and the light-emitting elements 22 are evenly distributed in the light-emitting region 2121; and the mounting region 2122 is located outside the light-emitting region 2121.

[0058] In some embodiments, the lamp body 1 is prepared by an aluminum extrusion molding process, and a convex strip 122 is formed on a molding side surface of the lamp body, that is, the inner side surface of the side plate 131, the convex strip 122 is a positioning rib, a boss 124 is arranged on the convex strip 122 facing the light source substrate 21, and the boss 124 abuts against the second mounting surface 212 of the light source element 21. This limiting mode replaces the traditional screw fixing or bonding fixing mode, reduces the production cost and improves the assembly efficiency.

[0059] Further, the boss 124 has a V-shaped or C-shaped structure, and the boss 124 abuts against the mounting region 2122 of the second mounting surface 212. When the lamp body 1 is molded, the boss 124 adopts a V-shaped or C-shaped rounded step structure, which can effectively avoid the generation of processing burrs; meanwhile, when the boss 124 with the V-shaped or C-shaped rounded step structure abuts against the second mounting surface 212 of the light source substrate 21, a line (point)-surface connection mode is adopted, which ensures the tight attachment and connection between the first mounting surface 211 of the light source substrate 21 and the base surface 110 of the lamp body 1, and improves the heat dissipation effect. The boss 124 is only connected with the light source substrate 21 at the mounting region 2122, and does not affect the light-emitting region 2121.

[0060] With further reference to Figure 2 and Figure 3 , the base surface 110 has a normal line L, on the transverse cross-section of the lamp body structure 100 passing through the normal line L, the boss 124 has a convex point 125, the distance between the convex point 125 and the base surface 110 is H1, the thickness of the light source substrate 21 is H2, and H1 and H2 satisfy the following relational expression: H1 ≤ H2. When H1 = H2, the distance between the convex point 125 and the base surface 110 is equal to the thickness of the light source substrate 21, and the light source substrate 21 is just pushed into and plugged into the accommodating groove 131; when H1 < H2, the distance between the convex point 125 and the base surface 110 is smaller than the thickness of the light source substrate 21, but the difference between the two is small, after the light source substrate 21 is pushed into and plugged into the accommodating groove 131, the boss 124 and the second mounting surface 212 form an interference fit.

[0061] Multiple light-emitting elements 22 together form a light-emitting surface 220, and the distance between the light-emitting surface 220 and the base surface 110 is H3. The protrusion 122 has a top surface 126, which is opposite to the protrusion 124, meaning the top surface 126 is located on the side of the protrusion 122 away from the base surface 110. The distance between the top surface 126 and the base surface 110 is H4. H3 and H4 have the relationship: H4 > H3. That is, the light-emitting surface 220 is located above the top surface 126 of the protrusion 122. In this way, the light emitted by the light-emitting elements 22 will not be interfered with or blocked by the protrusion 122 and can be directly emitted from the cover plate 31, or reflected by the inner surface of the side plate 121 before being emitted from the cover plate 31. The inner surface of the side plate 121 may be coated with a reflective film.

[0062] The lamp body structure provided in this embodiment has a light source component that is pushed into the receiving groove of the lamp body. The lamp body adopts a rounded step structure to form a boss, which avoids the problem of burrs during processing. At the same time, the boss of the lamp body structure and the light source substrate adopt a line (point)-surface contact limiting structure to ensure the overall tightness of the fit between the light source component and the lamp body, making the whole lamp structure robust and with good heat dissipation.

[0063] In addition, since the light source assembly is installed into the lamp body by a push-in installation method, there is no need to drill screw holes or apply glue to the lamp body; moreover, the light source assembly can be pre-processed as an independent part, which expands the working space; after being pushed in and inserted into the receiving slot, the boss abuts against the light source substrate to limit the position, which improves the assembly efficiency and stabilizes the position of the light source assembly to ensure the light output effect.

[0064] Example 2

[0065] exist Figures 1-4 Based on reference Figure 5 This embodiment describes the cooperation between the first connecting arm of the lamp body and the second connecting arm of the cover. The first connecting arm 123 is located at the end of the side portion 12 away from the base 11. The first connecting arm 123 includes a support platform 1231, a limiting block 1232, and a slot 1233. The limiting block 1232 and the slot 1233 are respectively located on the upper and lower sides of the support platform 1231. The limiting block 1232 is formed by extending the first connecting arm 123 outward from its end, that is, the limiting block 1232 extends to the outer side of the side plate 121. The slot 1233 is formed by the first connecting arm 123 recessed inward from the direction away from the receiving cavity 13, that is, the first connecting arm 123 is recessed from the inside to the outside on the lower side of the support platform 1231 to form the slot 1233.

[0066] like Figure 2As shown, in the cover 3, the second connecting arm 32 extends from the cover plate 31 toward the base surface 110. The second connecting arm 32 includes a first contact block 321 and a second contact block 322. The first contact block 321 first extends downward in the height direction Z from the side of the cover plate 31 toward the base surface 110, and then bends inward in a transverse direction X to form a curved shape. The second contact block 322 continues to extend downward in the height direction Z at the end of the first contact block 321, then bends outward in a transverse direction X, and then bends inward to form a curved shape.

[0067] The first contact block 321 is located inside the limiting member 1232 and is supported by the support platform 1231; the second contact block 322 is engaged in the slot 1233. In this way, the second connecting arm 32 is engaged with the first connecting arm 123, thereby detachably connecting the cover 3 and the lamp body 1.

[0068] In addition, the second connecting arm 32 also includes a groove 323, which is formed by the first contact block 321 and the second contact block 322, and the groove 323 is located on the outside of the second connecting arm 32. When the second connecting arm 32 is engaged with the first connecting arm 123, the support platform 1231 is also engaged in the groove 323.

[0069] refer to Figure 6 The light source assembly 2 is pushed into the receiving groove of the lamp body 1. Further, during the installation of the cover 3 into the lamp body 1, the cover 3 can be inserted into the lamp body 1 longitudinally (Y) or snapped into the lamp body 1 vertically (Z). That is, the cover can simultaneously satisfy both longitudinal push-in and top-and-bottom snap-fit ​​installation methods. In addition, both the second connecting arm and the first connecting arm can undergo elastic deformation, which can guide and complete the assembly during snap-fit ​​installation, releasing assembly stress.

[0070] The lamp body structure provided in this embodiment has a light source component that is pushed into the receiving groove of the lamp body. The cover and the lamp body are connected by the second connecting arm and the first connecting arm and can be detachably assembled together, which facilitates the replacement of components during the installation and maintenance of the whole lamp.

[0072] This embodiment provides a lighting device having a linear or strip structure, including end caps and a lamp body structure 100 provided in embodiment 1 or 2. The end caps are installed longitudinally at both ends of the lamp body to seal the ends of the lamp body.

[0073] The lighting device provided in this embodiment adopts a lamp body with a rounded corner stepped structure to avoid the problem of burrs during processing. At the same time, the boss of the lamp body structure and the light source substrate adopt a line (point)-surface contact limiting structure to ensure the overall tightness of the fit between the light source component and the lamp body, making the whole lamp structure robust and with good heat dissipation.

[0074] The above description is merely an example and illustration of the structure of this utility model, and while the description is quite specific and detailed, it should not be construed as limiting the scope of this utility model patent.
