A control circuit board 20 is mounted in the circuit mounting groove 11. A conductive wire 21 is connected to the end of the control circuit board 20. A limiting slot 12 is provided at the end of the circuit mounting groove 11. A wiring through hole 121 is formed on the surface of the limiting slot 12. One end of the conductive wire 21 extends outward through the wiring through hole 121. A limiting sealing block 22 is sleeved on the outside of the conductive wire 21. The limiting sealing block 22 is engaged in the limiting slot 12 to limit and seal the conductive wire 21, preventing dust, moisture, and other impurities from entering the circuit mounting groove 11 and improving the overall protective performance of the downlight.

[0023] In practical implementation, the limiting slot 12 has limiting surfaces 122 on both sides, and each end of the limiting surfaces 122 has a protruding fixing buckle 123. The limiting sealing block 22 has corresponding fixing positions 221 on both sides, which are adapted to the fixing buckles 123. The two limiting surfaces 122 are respectively engaged with the sides of the limiting sealing block 22, and the fixing buckles 123 and fixing positions 221 are locked together, thus ensuring the limiting sealing block 22 is stably installed in the limiting slot 12. During use, after the conductive wire 21 passes through the wire through hole 121, the limiting sealing block 22 can be quickly installed in the limiting slot 12 through a snap-fit ​​mechanism, achieving a tight sealing and fixing of the conductive wire 21.

The sealing cap 40 can be made of flexible silicone material, possessing good elasticity and resilience, allowing it to fit tightly against the edge of the adjustment slot 112 during installation, enhancing the sealing effect, and facilitating easy disassembly and replacement when needed.

[0029] In practical implementation, the lower end of the circuit mounting groove 11 is provided with a lamp board mounting groove 14. A light source lamp board 50 is mounted on the inner surface of the lamp board mounting groove 14. A plurality of positioning protrusions 141 are evenly distributed on the inner surface of the lamp board mounting groove 14. A plurality of positioning through holes 51 are evenly distributed on the surface of the light source lamp board 50.

[0031] In practical implementation, an isolation panel 70 is attached and fixed to the lower surface of the control circuit board 20. The isolation panel 70 is disposed between the control circuit board 20 and the light source panel 50. During use, the isolation panel 70 can effectively isolate the heat generated by the control circuit board 20 and the light source panel 50, prevent heat conduction from affecting the stable operation of the control circuit board 20, and improve the overall heat dissipation efficiency and safety of the downlight.

[0032] In practical implementation, the isolation panel 70 is made of high-temperature resistant insulating material, which has good thermal resistance and electrical insulation properties. It can ensure the safe isolation between the control circuit board 20 and the light source board 50 during long-term use of the downlight, prevent heat or electrical interference from affecting the stable operation of the control circuit board 20, thereby improving the overall safety and reliability of the downlight.
