Detailed ways

Referring to Figures 1 to 2, the waterproof structure of a LED lighting module provided by the present invention includes a light emitting diode 1 and a cooling rod 2 with a through hole 21 inside, and the front of the cooling rod 2 is provided with a connecting through hole 21 Mounting hole 22, the light emitting diode 1 is disposed in the mounting hole 22, and the power connection device at its tail is connected to the external circuit through the through hole 21, for example, the common light emitting diode 1 is disposed on the circuit board, and the circuit board leads out wires, The wire comes out from the through hole 21, and it can be easily connected with the outside world. Since the opening of the through hole 21 is located at the side end of the cooling rod 2, when the entire lighting module is installed, the opening can directly lead the wire out to the tail of the street lamp. The tail of the whole lamp body is convenient to connect with the wire of the electric pole; the heat dissipation panel 4 is connected to the front of the heat dissipation rod 2, and the heat dissipation panel 4 can increase the heat dissipation effect of the whole lighting module, and the connection mode with the heat dissipation rod 2 can be screw, Common connection methods such as card positions are provided with an opening 41 corresponding to the position of the mounting hole 22 on the heat dissipation panel 4, so that the light source when the light-emitting diode 1 is working can be irradiated through the opening 41; the light-emitting diode in the mounting hole 22 1. A reflector 3 is provided in front, which can enhance the lighting effect. A light-transmitting mirror 5 is arranged in front of the reflector 3 to achieve better lighting effects. Between the front of the light-transmitting mirror 5 and the opening 41 of the heat dissipation panel 4 The sealing ring 6 that rubber or other materials are made is housed in the pressure, so that the components such as the light-emitting diode 1 inside are separated from the outside world of the front, and the waterproof effect is achieved.

Wherein as the preferred mode of the present utility model, the outside of the front part of the reflector 3 is provided with an external thread, and the rear of the opening 41 of the heat dissipation panel 4 is provided with a raised positioning groove 42, and the positioning groove 42 is provided with the reflector 3 The external thread of the reflector 3 is installed together with the heat dissipation panel 4 through the thread, so that the fixing of the two is more stable, and the sealing effect of the sealing ring 6 in front of the light-transmitting mirror 5 is better.

Referring to Fig. 3, it is preferable that the front of the heat dissipation rod 2 is provided with two or more mounting holes 22 for installing the light emitting diodes 1 along the longitudinal direction, so as to achieve a structure in which one heat dissipation rod 2 cooperates with a plurality of light emitting diodes 1, and ensures that each light emitting diode 1 The diode 1 has a sealing and waterproof effect, and a light-emitting module composed of multiple cooling rods 2 can be configured in a street lamp according to actual needs.
