[0025] The technical solution of this utility model will be described in detail below with reference to the illustrations.
[0026] Please see Figures 1-4 As shown, the novel photovoltaic LED ground socket light of this embodiment includes a top cover 1, a photovoltaic panel 2 disposed on the top cover 1, a bottom cover 3 of the top cover 1 welded by ultrasonic welding, a ground socket plate 4, and a ground socket 5 inserted into the ground socket plate 4. A battery 6, a circuit board 7 and an LED light source 8 are disposed in the cavity formed by the top cover 1 and the bottom cover 3. The top cover 1 and the bottom cover 3 are light-transmitting.
[0027] Further as Figure 3 and Figure 4 As shown, the top of the ground socket 4 passes through the through hole 31 on the bottom cover 3 and enters the receiving cavity, and is screwed to the top cover 1. The bottom surface of the ground socket 4 is provided with a manual switch 9 for the LED light source 8. The top cover 1 is provided with a wire hole 11, and the circuit board 7 is electrically connected to the photovoltaic panel 2, the battery 6 and the LED light source 8 through wires (not shown).
[0028] In this embodiment, the top cover 1 and bottom cover 3 are ultrasonically welded together to form the outer shell of the lamp body. This connection method can effectively improve the sealing effect at the connection point, achieving the purpose of dustproof and waterproof. It can eliminate the need for the waterproof ring traditionally used at the connection point of the top cover 1 and bottom cover 3, thereby effectively saving the cost of the lamp.
[0029] like Figure 4 and Figure 5 As shown, in order to achieve the connection stability between the ground socket 4 and the top cover 1, and to prevent the screws from being exposed on the side wall of the lamp body, in one embodiment, a plurality of hollow studs 12 spaced apart are provided on the bottom surface of the top cover 1. The working ends of the plurality of screws pass through the screw holes 41 on the ground socket 4 and enter the receiving cavity to be screwed into the plurality of hollow studs 12.
[0030] like Figure 8 As shown, a ring-shaped plate 42 is integrally formed on the top surface of the floor socket 4, and an LED light source 8 is arranged around the outer wall of the ring-shaped plate 42. Furthermore, it is preferable that the LED light source 8 is an LED light strip, thereby ensuring uniform circumferential luminous intensity of the lamp housing.
[0031] Further as Figure 8As shown, in one embodiment, a battery electrode frame 43 is integrally formed on the top surface of the ground socket 4, and the battery 6 is snapped into the battery electrode frame 43; the battery electrode frame 43 and the circuit board 7 are located in the space enclosed by the annular plate 42, so that the circuit board 7 and the battery 6 are stably limited on the top surface of the ground socket 4.
[0032] Further as Figure 6 , Figure 7 and Figure 8 As shown, the floor insert 4 is a circular plate with at least one first positioning protrusion 44 on its outer circumference. The through hole 31 on the bottom cover 3 is provided with a first positioning notch 32 that matches the first positioning protrusion 44. The matching connection between the first notch 32 and the first positioning protrusion 44 serves to pre-connect the floor insert 4 and the bottom cover 3.
[0033] like Figure 5 and Figure 6 As shown, in one embodiment, a second positioning notch 13 is provided on the circumference of the bottom opening of the top cover 1, and a second positioning protrusion 33 matching the second positioning notch 13 is provided on the inner surface of the bottom cover 3. When the two are connected, the second positioning protrusion 33 and the second positioning notch 13 are first connected to each other, and then ultrasonic welding is performed to make the bottom cover 3 and the top cover 1 accurately aligned and convenient for ultrasonic welding.
