[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1

[0022] Reference Figure 1-4 A multi-chip integrated full-spectrum dimmable LED street light includes a light pole 1, a light panel 2, and an LED lamp body 3. The light panel 2 is fixedly connected to the top of the light pole 1, and the LED lamp body 3 is disposed at the bottom of the light panel 2. A support rod 4 is fixedly connected to the wall of the light pole 1. The end of the support rod 4 away from the light pole 1 is fixedly connected to the bottom of the light panel 2. A connecting pipe 5 is fixedly connected to the top of the light panel 2. A housing 6 is fixedly connected to the top of the light panel 2. An end cap 7 is inserted into the side wall of the housing 6. A connecting plate 8 is fixedly connected to the side wall of the end cap 7. A circuit board 9 is fixedly connected to the upper surface of the connecting plate 8. A spiral wire 10 is electrically connected to the top of the circuit board 9. The end of the spiral wire 10 away from the circuit board 9 passes through the connecting pipe 5 and is electrically connected to the LED lamp body 3.

[0023] A support block 11 is fixedly connected to the bottom of the connecting plate 8. The bottom of the support block 11 is slidably disposed on the inner wall of the box 6. A guide block 12 is fixedly connected to the inner wall of the support block 11. A guide groove is provided on the inner wall of the box 6. The guide block 12 is slidably disposed on the inner wall of the guide groove. A ball bearing 13 is rolled on the inner wall of the bottom end of the support block 11.

[0024] The inner wall of the end cap 7 has a cavity, and a spring 14 is fixedly connected to the inner wall of the cavity. A plug 15 is fixedly connected to the top of the spring 14. The inner wall of the box body 6 has a slot, and the plug 15 is inserted into the inner wall of the slot.

[0025] The light pole 1 serves as the supporting foundation for the street light. The light plate 2, fixed at the top, is used to install the LED light body 3. One end of the support rod 4 on the wall of the light pole 1 is fixed to the bottom of the light plate 2, which can enhance the connection stability between the light plate 2 and the light pole 1, prevent the light plate from tilting due to wind or vibration, and ensure the stable lighting direction of the LED light body 3. The LED light body 3 adopts a multi-chip integrated design. Different chips can emit light of different wavelengths. The luminous intensity and combination of different chips are controlled by the circuit to achieve full-spectrum lighting. At the same time, it supports brightness adjustment to adapt to the lighting needs of different scenarios such as roads and squares.

[0026] The housing 6 at the top of the lamp board 2 is the mounting carrier for the core circuit control. The circuit board 9 is fixed inside by the connecting plate 8. The circuit board 9 is the control center of the LED lamp body 3. It can receive external control signals and output corresponding current signals to control the light emission state of the LED lamp body 3, realizing full spectrum adjustment and brightness control. The spiral wire 10 electrically connected to the top of the circuit board 9 passes through the connecting tube 5 at the top of the lamp board 2 and is electrically connected to the LED lamp body 3. The spiral wire can freely stretch and contract with the slight deformation of the lamp board 2 to avoid the wire being pulled and broken. At the same time, the connecting tube 5 can protect the wire from rain and dust corrosion and ensure stable circuit connection.

[0027] The support block 11 fixed at the bottom of the connecting plate 8 is slidably disposed on the inner wall of the housing 6. The guide block 12 on the inner wall of the support block 11 slides in conjunction with the guide groove of the housing 6 to provide guidance for the installation and removal of the connecting plate 8 and the circuit board 9, ensuring accurate positioning of the circuit board. The ball bearing 13 on the inner wall at the bottom of the support block 11 rolls in contact with the inner wall of the housing 6, reducing the resistance to movement of the support block and making it easier to pull the circuit board 9 out of the housing 6 for inspection or replacement, thus improving maintenance efficiency.

[0028] The end cap 7, which is inserted into the side wall of the enclosure 6, is used to seal the enclosure 6 and prevent rainwater and dust from entering the enclosure and damaging the circuit board 9. The spring 14 in the cavity of the inner wall of the end cap 7 has a pre-tightening force, which pushes the plug 15 to be inserted into the slot in the inner wall of the enclosure 6, thereby fixing the end cap 7 to the enclosure 6 and preventing the end cap from loosening and falling off.

[0029] Example 2

[0030] Reference Figure 1-4 A pull rope 16 is fixedly connected to the connection between the insert block 15 and the spring 14. A rectangular groove is provided on the inner wall of the end cap 7. A rotating shaft 17 is rotatably connected to the inner wall of the rectangular groove. One end of the pull rope 16 away from the insert block 15 is fixedly connected to the shaft wall of the rotating shaft 17. A handle 18 is fixedly connected to the end of the rotating shaft 17. A damping ring 19 is fixedly connected to the inner wall of the end cap 7. The damping ring 19 is fitted against the side wall of the handle 18.

[0031] When it is necessary to open the end cover, rotate the handle 18 at the end of the shaft 17 in the rectangular groove on the inner wall of the end cover 7. The shaft 17 is wound with the pull rope 16, which pulls the insert 15 to compress the spring 14, causing the insert to disengage from the slot, and the end cover 7 can be pulled out. The damping ring 19 fixed on the inner wall of the end cover 7 is attached to the side wall of the handle 18. The damping force restricts the handle 18 from rotating freely, preventing the insert 15 from disengaging from the slot when not in operation, and ensuring the reliability of the end cover 7.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
