[0030] The following is a detailed explanation of the implementation of the present invention in conjunction with the accompanying drawings. The accompanying drawings are for reference and illustration only and do not constitute a limitation on the scope of patent protection of the present invention.

[0031] Reference Figures 1 to 10 A waterproof plug structure of a flexible wall washer lamp includes a lamp body component 1 and a connector 5. A flexible circuit board 2 is accommodated in a cavity 112 of the lamp body component 1. The connector 5 is arranged outside the lamp body component 1. The connector 5 is arranged along the axial direction of the lamp body component 1 and points to the lamp body component 1. A power lead 51 of the connector 5 is bent and extends into the cavity 112 and is welded to the flexible circuit board 2. The lamp body component 1 and the power lead 51 are integrally formed by silicone injection molding to form a plug 4. The power lead 51 is sealed and connected to the lamp body component 1 through the plug 4.

[0032] Reference Figures 2 to 5 The lamp body assembly 1 includes a lamp body 11 and two inner covers 12. The lamp body 11 is in an elongated ring shape and is made of a flexible material. The left and right end surfaces of the lamp body 11 are hollowed out. A wire inlet groove 113 is respectively provided on the two end surfaces of the lamp body 11. Long strip-shaped card grooves 111 are respectively provided on the two opposite inner walls of the lamp body 11 along the axial direction thereof. The two inner covers 12 have the same structure. Card platforms 121 are respectively provided on the two opposite sides of the inner cover 12. When the two inner covers 12 are respectively covered on the two end surfaces of the lamp body 11 and the cavity 112 is formed, the two card platforms 121 on each inner cover 12 are carded with the two card grooves 111 in the lamp body 11 in a one-to-one correspondence. Since the inner cover 12 is located in the lamp body 11, the outer end surface of the inner cover 12 is connected to the end surface of the lamp body 11. The two inner covers 12 are respectively provided on two wire entry grooves 113 at the two end faces of the lamp body 11 to form wire entry holes for the power lead 51 to extend into. The two wire entry holes are located at the two ends of the bottom of the lamp body 11 and are connected to the cavity 112. When the inner cover 12 is covered on the end face of the lamp body 11, the power lead 51 passes through the wire entry hole and enters the cavity 112. The plug 4 covers the wire entry hole, so that the power lead 51 is sealed and connected to the inner cover 12 and the lamp body 11 through the plug 4, preventing external water from entering the cavity 112 from the wire entry hole.

[0033] Reference Figures 4 to 7The flexible circuit board 2 is in the shape of a long square wave as a whole. The bottom of the flexible circuit board 2 is clamped with the slots 111 of the lamp body 11 through multiple heat sinks 3. Specifically, multiple grooves are arranged at intervals on the flexible circuit board 2. Multiple heat sinks 3 are arranged one-to-one on the bottom wall of the groove of the flexible circuit board 2. The two ends of each heat sink 3 are respectively inserted into the two slots 111. Two clamping holes 31 are provided on the heat sink 3. In order to clamp the heat sink 3 with the flexible circuit board 2, an annular bracket 22 is provided in each groove. Multiple lamp beads 21 on the flexible circuit board 2 are arranged one-to-one in multiple brackets 22. Two buckles 221 are provided at the bottom of each bracket 22. After passing through the flexible circuit board 2, the two buckles 221 are clamped with the two clamping holes 31 on the heat sink 3, so that the flexible circuit board 2 can be clamped with multiple heat sinks 3 one-to-one through multiple brackets 22. An optical lens 23 is also installed in each bracket 22. The light emitted by the lamp bead 21 can be refracted through the optical lens 23 and then pass through the lamp body 11 to the outside of the wall washer.

[0034] Reference Figures 2 to 5 In the utility model, there are two connectors 5 and two plugs 4. Both connectors 5 are located below the lamp body 11 and are symmetrically arranged. The power lead 51 of each connector 5 is bent and passes through the wire entry hole on the side wall of the lamp body 11, and then is electrically connected to the flexible circuit board 2. The two plugs 4 are symmetrically arranged. Each plug 4 is L-shaped. The upper end of the plug 4 covers the end surface of the lamp body 11 and the end surface of the inner cover 12, and the lower end of the plug 4 covers the bent part of the power lead 51. Each connector 5 is connected to the lamp body assembly 1 through its power lead 51 to form a U shape. The power leads 51 of the two connectors 5 are sealed and connected to the two ends of the lamp body assembly 1 through their respective plugs 4 in a one-to-one correspondence.

[0035] The preparation method of the flexible wall washer lamp of the utility model is as follows: firstly, a flexible circuit board 2 equipped with a bracket 22, an optical lens 23 and a heat sink 3 is installed in a lamp body 11, a plurality of heat sinks 3 are clamped on the clamping grooves 111 on the inner wall of the lamp body 11, and the power leads 51 of the two connectors 5 are respectively welded to the two ends of the flexible circuit board 2, and the inner cover 12 is covered, and then the power lead 51 and the lamp body assembly 1 are put into the injection mold 6 (such as Figure 8 As shown), the lamp is injection molded by silicone, and the lamp after injection molding is integrated with the power lead 51 of the connector 5, and is inseparable, and has good tensile resistance, flexural resistance, and extrusion resistance.

[0036] like Fig. 9As shown, in the utility model, when a single wall washer lamp is used, the power lead 51 of the connector 5 needs to be turned outward by 180 degrees, so that the power lead 51 is in the shape of a paper clip, so that the connector 5 points to the outside of the wall washer lamp, which effectively enhances the pulling force of the power lead 51. Since the plug 4, the power lead 51 and the lamp body assembly 1 are integrated into a whole through injection molding, the protection ability of the power lead 51 is greatly increased, which can effectively prevent the workers from using violent installation to cause the power lead 51 to become loose or broken. When multiple wall washer lamps are connected and used, the power leads 51 of two adjacent wall washer lamps are connected together through their respective connectors 5 (such as Fig.10 As shown), multiple wall washers can be used at the same time.

[0037] The waterproof plug structure of the flexible wall washer lamp of the utility model utilizes silicone to be injection molded on the lamp body assembly 1 and the power lead 51 to form the plug 4, so that the lamp body assembly 1, the power lead 51 and the plug 4 become an inseparable sealed whole. At the same time, the power lead 51 of the connector 5 is bent and extends into the lamp body assembly 1, so that when the wall washer lamp is in use, the power lead 51 is in the shape of a paper clip. The whole structure not only has strong tensile and drop resistance, but also effectively prevents the lead from falling off and the plug 4 from loosening due to violent installation by on-site installers, and can also improve the waterproof performance and ensure the service life of the lamp.

[0038] The above disclosure is only a preferred embodiment of the present invention, which cannot be used to limit the scope of protection of the present invention. Therefore, equivalent changes made within the scope of the patent application of the present invention are still within the scope covered by the present invention.
