Description

Technical Field

[0001] The utility model relates to the technical field of lighting equipment, in particular to a lampshade installation structure of a plastic-coated aluminum lamp holder. Background Art

[0002] In recent years, LED lamps have been widely used in various lighting occasions due to their high efficiency, energy saving and long life. Among them, plastic-coated aluminum lamp holders, as a LED lamp base that combines the lightness of plastic and the strength of aluminum alloy, have shown certain advantages among many lighting solutions.

[0003] like Figure 1 As shown, in the conventional manufacturing process of the plastic-coated aluminum lamp holder, the holder body is usually made by injection molding on the basis of the aluminum blank 100. However, this manufacturing method causes the end of the holder body to be in close contact with the end of the aluminum blank 100, and the slot formed by stamping at the end of the aluminum blank 100 is usually limited in width. After the lampshade is installed on the slot, there is no extra space in the slot for the glue layer that fixes the two to be thickened, so that it cannot provide sufficient mechanical strength to resist the stress caused by factors such as environmental changes, resulting in the lampshade being not installed firmly enough, or even falling off.

[0006] As a further optimization scheme of the utility model, a retaining ring capable of limiting the glue flowing toward the aluminum cup is provided between the mounting ring and the aluminum cup, and a mounting groove for mounting and bonding the lampshade is formed between the mounting ring and the retaining ring, and the glue coating area is provided in the mounting groove.

[0007] As a further optimization solution of the utility model, the inner side wall of the mounting ring is provided with a guiding inclined surface for facilitating the insertion of the lampshade.

[0008] As a further optimization solution of the utility model, the inner side wall of the mounting ring is provided with a limiting convex ring for limiting the lampshade from falling out.

[0010] As a further optimization solution of the present utility model, a snap ring is provided on the upper part of the cup wall, and the radiator is provided with a clamping groove that cooperates with the snap ring to limit the aluminum cup from coming out.

[0011] Compared with the prior art, the present utility model has the following advantages: by providing an adhesive application area between the mounting ring and the aluminum cup, when the lamp cover is bonded to the mounting ring through adhesive application, the adhesive application area can accommodate the excess glue, so that the adhesive application forms an adhesive layer, thereby enabling the lamp cover to obtain sufficient buffering and support through this adhesive layer and avoiding falling off.

[0019] The following describes in detail the embodiments of the present utility model with reference to the drawings.

[0020] As Figures 2 to 6 shown, the present utility model discloses a lamp cover mounting structure of a plastic-coated aluminum lamp holder, including a radiator 1 made of plastic. The radiator 1 is provided with a receiving groove 11, and an aluminum cup 2 is arranged in the receiving groove 11. The aluminum cup 2 includes an annular cup wall 21, and the cup wall 21 is arranged in contact with the inner wall of the receiving groove 11. An extension part 12 extends outward from the upper part of the radiator 1, and a mounting ring 121 capable of being bonded to the lamp cover through adhesive application is arranged on the extension part 12. An adhesive application area 3 capable of accommodating the adhesive application to form an adhesive layer when the lamp cover is bonded to the mounting ring 121 is arranged between the mounting ring 121 and the aluminum cup 2.

[0021] The heat sink 1 made of plastic is provided with a receiving groove 11, so as to cooperate with the aluminum cup 2 to form a plastic-coated aluminum structure. The aluminum cup 2 includes an annular cup wall 21, and the cup wall 21 is arranged in a close contact with the inner wall of the receiving groove 11, so that the heat is transferred to the external environment through the aluminum cup 2, thereby achieving heat dissipation of the LED chip. The extension portion 12 provides a platform for the mounting ring 121 to fix the lampshade, so that the lampshade can be bonded to the mounting ring 121 by gluing. The gluing area 3 enables the gluing material to form a glue layer between the lampshade and the mounting ring, and the glue layer has sufficient thickness support, thereby improving the bonding strength between the lampshade and the heat sink 1, reducing the risk of plastic aging at the connection between the heat sink 1 and the lampshade, and improving the life of the lamp body.

[0022] By setting the glue coating area 3 between the mounting ring 121 and the aluminum cup 2, when the lampshade and the mounting ring 121 are bonded by gluing, the glue coating area 3 can accommodate excess glue, so that the glue forms a glue layer, so that the lampshade can obtain sufficient cushioning and support through this glue layer to avoid falling off.

[0023] A retaining ring 122 capable of limiting the flow of glue toward the aluminum cup 2 is provided between the mounting ring 121 and the aluminum cup 2 . A mounting groove 123 for mounting and bonding the lampshade is formed between the mounting ring 121 and the retaining ring 122 . The glue coating area 3 is provided in the mounting groove 123 .

[0024] The retaining ring 122 can limit the flow direction of the glue and improve the bonding quality. The mounting groove 123 is used to accommodate the lampshade and provide space for the glue. It ensures that there is enough space to form a glue layer when the glue is applied to enhance the bonding force. The installation of the mounting groove 123 can limit the shrinkage of the lampshade due to cold, which may cause the lampshade to fall off.

[0025] The inner side wall of the mounting ring 121 is provided with a guiding inclined surface 1211 for facilitating the insertion of the lampshade.

[0026] By providing the guiding inclined surface 1211 , the lampshade can be accurately inserted into and matched with the mounting ring 121 , thereby reducing the difficulty of installing the lampshade.

[0027] The inner side wall of the mounting ring 121 is provided with a limiting protruding ring 1212 for limiting the lampshade from falling out.

[0028] By providing the limiting protruding ring 1212 , the lampshade is prevented from loosening or falling off due to external factors during use, thereby improving reliability.

[0029] The cup wall 21 is cylindrical or truncated cone-shaped, and is connected to a bending surface 22 . The bending surface 22 is a plane or an inclined surface, and the bending surface 22 is arranged to fit the bottom surface of the receiving groove 11 .

[0030] The aluminum cup 2 includes a cylindrical or frustum-shaped annular cup wall 21 and a bent surface 22 connected to the cup wall 21 and being a plane or an inclined surface. Compared with an arc-shaped aluminum blank, it can be formed with fewer steps, which is convenient for production.

[0031] A snap ring 23 is provided at the upper part of the cup wall 21, and the radiator 1 is provided with a card slot 13 that cooperates with the snap ring 23 to limit the aluminum cup 2 from coming out.

[0032] Through the mutual cooperation of the snap ring 23 and the card slot 13, reliable fixation between the aluminum cup 2 and the radiator 1 is achieved, preventing the aluminum cup 2 from falling off.
