Background technique

Street lamps used on the road can provide lighting for pedestrians and vehicles, and are an indispensable facility in people's daily life. At present, common street lamps are divided into street lamps with ordinary light sources and LED street lamps with light-emitting diode light sources. Because LED street lamps have energy-saving The advantages of power saving, good lighting effect, and long service life have gradually begun to become popular. Now common LED street lamps are mainly composed of housings installed on electric poles and lighting modules installed in the housings. The lighting modules include light-emitting diode chips and corresponding power connection and heat dissipation structures. The use environment also has certain requirements for its water resistance; however, the lighting modules of LED street lights currently on the market are generally non-closed structures, and the parts are scattered, which is easy to enter water during use, which cannot achieve a good performance. Waterproof effect.

Contents of the invention

The purpose of the present invention is to provide a waterproof structure of an LED lighting module with a good waterproof effect.

The technical mode that the present invention adopts for solving its technical problem is:

A waterproof structure of an LED lighting module, including a light emitting diode, and a heat dissipation rod with a through hole inside. The front of the heat dissipation plate is provided with a mounting hole communicating with the through hole, and the light emitting diode is arranged in the mounting hole.

There is a light-transmitting mirror, and an apron is pressed between the front of the light-transmitting mirror and the opening of the heat dissipation panel.

The beneficial effects of the present invention are: the present invention adopts semi-enclosed heat dissipation rods to install light-emitting diodes, leads the lines of light-emitting diodes to connect with external circuits through through holes, and connects reflective cups, lenses, Components such as sealing rings are fixed together to realize the structure that the front and back of the light-emitting module are sealed, and at the same time, it has a good heat dissipation effect. The lines drawn out of the through holes are connected to the external circuits, and the other directions are relatively sealed and do not need to be adjusted. It is easy to install and is a lighting module with good waterproof and heat dissipation effects.

Detailed ways

Referring to Figures 1 to 2, a waterproof structure of an 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 for installation. hole 22, the light-emitting diode 1 is arranged in the installation hole 22, and the power connection device at its tail is connected to the external circuit through the through-hole 21. Coming out of the through hole 21, 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 heat dissipation rod 2, when the entire lighting module is installed, the opening can directly lead the wires to the entire lighting module facing the tail of the street lamp. The tail of the 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 entire lighting module. Common connection methods such as bits, etc., the heat dissipation panel 4 is provided with an opening 41 corresponding to the position of the mounting hole 22, so that the light source of the light-emitting diode 1 can be irradiated through the opening 41 when it is working; the light-emitting diode 1 in the mounting hole 22 The front is provided with a reflector 3, which can enhance the lighting effect, and a light-transmitting mirror 5 is arranged in front of the reflector 3 to achieve a better lighting effect, between the front of the light-transmitting mirror 5 and the opening 41 of the heat dissipation panel 4 A sealing ring 6 made of rubber or other materials is press-fitted, so that elements such as the light-emitting diodes 1 inside are separated from the outside world of the front, thus achieving a waterproof effect.

Wherein as a preferred mode of the present invention, 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 a connection with the reflector 3. The external thread matches the internal thread connected, and 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.

The heat dissipation rod 2 of the present invention is equipped with a light emitting diode 1 and a light emitting module combined with a heat dissipation panel 4. When installed in the street lamp housing, it only needs to be connected to the external circuit through the line drawn through the through hole, and the other directions are opposite. The seal does not need to be adjusted, and its installation is very convenient; the heat dissipation rod 2 only leads the wires from the opening direction of the through hole 21, so that the light emitting diode 1 installed in it forms a "semi-closed" structure. When installed in a street lamp, the through hole 21. One side of the lead wire directly cooperates with other structures such as an external circuit or a street lamp mounting seat, which can be effectively waterproof and dustproof, and through the heat dissipation rod 2 and the heat dissipation panel 4, it can have a good heat dissipation effect.

To sum up, the various components of the present invention are arranged in a centralized manner, which is a lighting module with good waterproof and heat dissipation effects.
