[0002] LED lamps that are mounted on an external mounting base using a bracket, such as linear lamps, outdoor lamps or wall washers, and whose lamp bodies / shells are also set in a long strip shape. Since they can outline the outline of large buildings according to needs, this type of LED lamp is mostly used for architectural decorative lighting or outdoor lighting.

[0003] like Figure 1 As shown, the long strip of lamp body is generally made by cold-rolled plate stamping + bending to obtain the lamp body bottom box, and then the bracket body is welded in the lamp body bottom box, and the end cover of the lamp body is screwed to the flange hole of the bracket body. Since it is difficult to ensure the sealing between the lamp body bottom box and the bracket body during welding, light leakage and water leakage are prone to occur. In addition, the welded bracket needs to be equipped with reflective paper to reflect the light emitted by the light source, which requires an additional bonding process, resulting in low assembly efficiency and high cost; in addition, due to the thickness of the bonded reflective paper or wrinkles on the plane, it will also cause dark area problems, thereby affecting the light output effect.

[0004] The prior art discloses a bracket lamp assembly structure, which includes a bracket assembly and a light source assembly. The end of the bracket assembly is provided with a first clamping portion, and the end of the light source assembly is provided with a second clamping portion.

The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0053] Example 1

[0054] refer to Figure 2-Figure 4This embodiment provides a lamp body structure 100, including a first bracket 1 and a second bracket 2, wherein the first bracket 1 is used as the main frame of the lamp body structure 100 and is formed by stamping of a cold-pressed plate or an aluminum profile; the first bracket 1 includes a first plate body 11 and a second plate body 12, the first plate body 11 is located at the bottom of the first bracket 1, and the second plate body 12 is disposed on both sides of the first plate body 11. In the first bracket 1 of this embodiment, the second plate body 12 is bent from the end of the first plate body 11 and extends upward. In the case of using metal parts such as cold-rolled plates or aluminum profiles, the second plate body 12 and the first plate body 11 can be made by an integrated stamping process to form a rigid first bracket 1; in this way, it can be ensured that the first bracket has a high frame structure strength under a relatively low weight.

[0055] The first plate body 11 and the second plate bodies 12 on both sides form a receiving chamber 10 for placing and installing the second bracket 2 and other lamp components. In addition, the second plate body 12 extends a support member 121 toward the receiving chamber 10 .

[0056] The second bracket 2 is embedded and installed in the accommodating chamber 10 of the first bracket 1, and no welding processes such as spot welding and butt welding are required during the installation process. The second bracket 2 includes a base 21, a side plate 22 and a reflector 23, wherein the base 21 is located at the bottom of the second bracket 2, the side plates 22 are arranged on both sides of the base 21, and the reflector 23 is obliquely arranged between the base 21 and the side plates 22.

[0057] The second bracket 2 of this embodiment is a plastic part, that is, the second bracket 2 can be made of a resin plastic material through an injection molding process. In some embodiments, the second bracket 2 can be made of polyethylene, polyvinyl chloride, polystyrene, polypropylene and polyurethane, as well as ABS plastic, through injection molding, blow molding, extrusion molding, compression molding or calendering molding. The base 21, the side plate 22 and the reflector 23 of this embodiment are integrally injection molded, and the base 21, the reflector 23 and the side plate 22 are together formed around the light-emitting chamber 20, and the light-emitting chamber 20 is provided with a light outlet 24. The light emitted by the light source assembly passes through the light-emitting chamber 20 and is emitted to the outside from the light outlet 24. In the second bracket 2, the side plate 22 extends in a direction away from the light outlet to form a convex block 221, and the convex block 221 abuts against the support member 121, so that the support member 121 supports the convex block 221, so that the second bracket 2 is stably embedded and installed in the accommodating chamber 10 of the first bracket 1.

[0058] Specifically, the support member 121 is formed by the second plate body 12 being grooved toward the accommodating chamber 10 and then being bent toward the light outlet 24. In the bending process, after the second plate body 12 is blanked and grooved, it can be vertically bent or arc-shaped bent toward the light outlet 24; at this time, the support member 121 is an L-shaped structure, and the support member 121 is provided with a limiting groove 122, and the protrusion 221 is inserted into the limiting groove 122.

[0059] Figure 4 This is a cross-sectional diagram of the lamp structure on the AA plane, for reference Figure 4 , the direction parallel to the plane where the light outlet 24 is located is the first direction x, and the direction perpendicular to the plane where the light outlet 24 is located is the second direction y; it can be understood that in this cross-sectional view, the first direction x can be considered as a horizontal direction, and the second direction y can be considered as a vertical direction. Limiting members are respectively arranged above the first bracket 1 and the second bracket 2, and the limiting members form mounting grooves for mounting optical components (not marked in the figure), and the optical components are respectively abutted against the first bracket 1 and the second bracket 2 in the second direction y; at the same time, since the protrusion 221 of the second bracket 2 is inserted into the limiting groove 122 of the support member 121, and the support member 121 abuts against the protrusion 221 in the second direction y, the second bracket 2 is limited in the second direction y and fixed in the first bracket 1.

[0060] The outer wall 220 of the side plate 22 is tightly connected with the inner wall 120 of the second plate body 12; the support members 121 of this embodiment are set to 6, and the 6 support members 121 are evenly distributed in the inner wall 120 of the second plate body 12. On the inner wall 120 of one side, the support members 121 are distributed in the middle and near the two ends of the first bracket 1; on the inner wall 120 of the other side, the support members 121 are symmetrically arranged with the opposite support members. In other embodiments, the number and position of the support members 121 can be adjusted as needed. The inner bending member 123 of the support member 121 together with the second plate body 12 prevents the protrusion 221 from shifting in the first direction x, so that the second bracket 2 is limited in the first direction x and fixed in the first bracket 1. It can be seen that the second bracket 2 can be directly inserted into the accommodating chamber from the end of the first bracket 1, without the need for spot welding, butt welding and other welding fixing processes, which can improve the assembly efficiency; and the first bracket 1 of this embodiment adopts an L-shaped support member 121, so as to limit the second bracket 2 in the horizontal and vertical directions, thereby ensuring the overall structural strength of the lamp body structure 100.

[0061] In some embodiments, the support member 121 can also be directly formed by blanking and grooving the second plate body 12, that is, no bending is required. At this time, the support member 121 is a straight-line structure; since the second bracket 2 and the first bracket 1 adopt an internal support interference fit installation method, the first bracket 1 can also limit and fix the second bracket 2 in the horizontal direction.

[0062] In some embodiments, the base 21 of the second bracket 2 is provided with a first mounting groove 211 and a second mounting groove 212, wherein the first mounting groove 211 is located in the middle of the base 21 for mounting the light source assembly; the second mounting groove 212 is provided on both sides of the first mounting groove 211 for mounting fasteners. In this embodiment, the first mounting groove 211 has a groove body structure that is narrow at the top and wide at the bottom, the second mounting groove 212 is a square groove body structure, and the second mounting groove 212 is provided with reinforcing ribs at the corners of the groove body to more firmly lock the fasteners. In other embodiments, the shapes of the first mounting groove 211 and the second mounting groove 212 can be adaptively designed and provided according to the shapes of the light source assembly and the fastener, for example, the second mounting groove 212 can be provided as a circular groove.

[0063] The reflective plate 23 is provided with a reflective layer 231, which is injection molded on the second bracket 2 to form the reflective plate 23, and a reflective coating is applied on the reflective plate 23 by coating or electroplating. In some embodiments, a material with a reflective material can also be used to form a reflective plate 23 with a reflective (film) layer during the injection molding of the second bracket 2. The reflective plate 23 of this embodiment does not need to be attached with reflective paper (reflective paper), which can save the pasting process on the one hand, and avoid the uneven light output caused by the reflective paper (reflective paper) not being pasted in place on the other hand.

[0064] The reflective layer 231 has a reflective surface, and the reflective surface forms an angle with the light emitting surface of the light source assembly. The reflective surface of the reflective layer 231 is disposed toward the light emitting port 24, thereby reflecting all the light entering the reflective layer to be emitted from the light emitting port.

[0065] In some embodiments, the second plate body 12 of the first bracket 1 is bent toward the light outlet 24 to form a first limiting member 124, and the side plate 22 of the second bracket 2 is also bent toward the light outlet 24 to form a second limiting member 222. A third mounting groove 223 is formed between the first limiting member 124 and the second limiting member 222, and the third mounting groove 223 is used to install the optical member; after installation, the first limiting member 124 and the second limiting member 222 are respectively abutted against the optical member to ensure that the position of the optical member is fixed.

[0066] In the lamp body structure provided in this embodiment, the second bracket is embedded and installed in the accommodating chamber of the first bracket, and the first bracket abuts against the protrusion of the second bracket through a support member extending toward the accommodating chamber. Without the need for welding process, the first bracket limits the second bracket in the horizontal and vertical directions, ensuring the overall structural strength of the lamp body structure and improving assembly efficiency; in addition, the second bracket adopts a reflective plate that does not require reflective paper, which effectively improves the light output efficiency while saving production costs.
