Detailed Implementation

[0021] The following is in conjunction with the appendix Figures 1-4 This application will be further described in detail below. The technical solutions in the embodiments of this application will be clearly described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0022] This application discloses a street light that can change color. For example... Figure 1 , Figure 2 , Figure 3 As shown, the device includes a lamp post 1, with a ground plug 11 fixedly connected to the bottom of the lamp post 1. The ground plug 11 allows the device to be easily inserted into the soil, facilitating installation. A slot 121 is provided at the top of the ground plug 11. A Y-shaped wire 12 is fixedly connected to the left side of the lamp post 1. A lower lamp cover 13 is provided above the slot 121. An assembly hole is provided at the bottom of the lower lamp cover 13, and the inner wall of the assembly hole is fixedly connected to the outer wall of the lamp post 1.

[0023] In this embodiment, a connector 2 is fixedly connected to the bottom of the inner wall of the lower lamp cover 13, and a claw 211 is fixedly connected to the outer wall of the lamp post 1 near the connector 2. A socket 21 is opened at the top of the connector 2, and a four-pin connector 231 is fixedly installed on the outer wall of the connector 2. The four-pin connector 231 is outside the power supply line and has a speed signal line, a PWM pulse width modulation signal line, etc.

[0024] Please see Figure 1 , Figure 4 As shown, the lower lamp cover 13 is threadedly connected to the inner wall of the upper lamp cover 3, and the top of the upper lamp cover 3 is provided with a threaded groove 31, and the inner wall of the threaded groove 31 is threadedly connected to the lamp cover screw 331.

[0025] Please see Figure 4 As shown, the inner wall of the threaded assembly groove is threadedly connected to the outer wall of the upper lamp cover 3, and the four-pin connector 231 is fixedly connected to the left side with a locking block 34.

[0026] Please see Figure 4As shown, the top of the card block 34 is in contact with the bottom of the left clamping jaw 211, and the bottom of the card block 34 is arc-shaped, so that it can push the two clamping jaws 211 to rotate to the sides when pressed downward, making installation more labor-saving. The number of the bottom card block 34 is two, and the two card blocks 34 are symmetrically arranged around the four-pin connector 231.

[0027] Please refer to Figure 2 As shown, the number of the jack 21 is several, and the several jacks 21 are arranged in a horizontal array. The top of the lower lamp shade 13 is fixedly connected with the waterproof ring 22.

[0028] Please refer to Figure 4 As shown, the bottom of the lamp cover screw 331 is in contact with the upper lamp cover 33 away from the threaded groove 31. The bottom of the upper lamp cover 33 is in contact with the lower lamp cover 32, and the bottom of the lower lamp cover 32 is provided with a threaded assembly slot.

[0029] Please refer to Figure 3 As shown, the top of the four-pin connector 231 is fixedly connected with the six-W lamp cup 23. The number of the clamping jaw 211 is two, and the clamping jaw 211 is made of thermoplastic rubber. Thermoplastic rubber has similar elasticity and flexibility to rubber at room temperature, can deform greatly, and can quickly recover to its original shape after external force is removed. The two clamping jaws 211 are symmetrically arranged around the connecting head 2.

[0030] The implementation principle of the color changeable street lamp embodiment of the present application is as follows: the device adopts a four-pin connector 231, which is connected with four insertion holes 21 on the connecting head 2 through the four-pin connector 231. Since the four-pin connector 231 increases a signal transmission line on the basis of power transmission, in addition to the power supply line, there are a rotating speed signal line, a PWM pulse width modulation signal line, etc. For the device capable of realizing color changeable lamp effect, in addition to the power supply pin, the remaining pins are used to transmit control signals to control the on-off and brightness of different color LED lamp beads. The color mixing and change effect is realized through the control circuit. Compared with the single-color constant light lamp bead controlled by the two-pin connector in the past, the device can meet the different personalized needs of users, avoid the monotonous and boring landscape caused by single color, and create diversified visual effects through color replacement. When the six W lamp cup 23 is damaged or needs to be repaired, the six W lamp cup 23 can be pulled out from the inner wall of the lower lamp shade 13 by holding the upper lamp shade 3 and counterclockwise twisting. Since the position where the pawl 211 contacts the top of the clamping block 34 is arc-shaped, and the pawl 211 is made of thermoplastic rubber, when the six W lamp cup 23 is pulled, the pawl 211 will move to both sides until the clamping block 34 is disengaged. At this time, the six W lamp cup 23 can be disassembled. When installing it, since the bottom of the clamping block 34 is arc-shaped, the four-pin connector 231 can be aligned with the connecting head 2 and pressed downward to quickly disassemble. By counterclockwise twisting the lamp cover screw 331, the air can be pulled out of the thread groove 31. At this time, the lower lamp cover 32 and the upper lamp cover 33 are also disengaged from the restriction of the lamp cover screw 331, and can be quickly disassembled. Compared with the integral type lawn lamp in the past, the device does not need to be replaced as a whole after damage, and is also more simple to disassemble, and will not cause waste of resources.

[0031] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, equivalent changes made on the basis of the structure, shape, principle of the present application should be covered within the protection scope of the present application.
