Description

Inlaid side-emitting flexible panel lamp and manufacturing method thereof

Technical field

The invention relates to the field of LED lighting, in particular to an inlaid side-emitting flexible panel lamp and a manufacturing method thereof.

Background technique

Traditional LED panel lights are divided into direct light-emitting panel lights and side-emitting panel lights. Direct light-emitting is that the LED light bar is installed on the back of the panel light, and the LED light-emitting surface faces the front and directly hits the diffuser plate of the panel light through the diffuser plate. After the light is diffused, the light is transmitted. This direct type must maintain a long distance between the LED and the diffuser to make the diffused light more uniform. Therefore, the panel lights produced are very thick, bulky, and more The individual components and the shell are assembled with many gaps and cannot be waterproof. They can only be used indoors. They are rigid panel lights and cannot be bent at any position during use.

Another type of side-emitting panel light is also made of rigid materials. The light guide plate, diffuser plate and housing are all made of rigid materials. Although the light bar is also on the side facing the light guide plate to achieve a thinner volume, it is because they are all made of rigid materials. Assembling, it is impossible to make a very long panel light. At present, it can be made up to 2 meters long, and it is assembled from a variety of structural parts. It cannot be fully enclosed and fully waterproof. It can only be used indoors, and the materials used are mostly rigid materials. As a result, it is impossible to make a panel light that can be bent at any position when in use, and because multiple structural parts are used to assemble, the assembly efficiency is low, and the assembly cost is high. Moreover, it is not a closed waterproof structure and can only be used indoors. .

In order to overcome the above shortcomings and many deficiencies, the panel light becomes flexible, ultra-thin, and ultra-long. It can be bent at will during use, and it can be cut at any set position at any time during production. It can be produced automatically and continuously, and it is a fully enclosed waterproof panel light. The present invention fully solves the above problems. An automatic plastic extruder is used to continuously extrude the LED flexible light bar and the light-transmitting flexible resin through an extrusion die. The light bar is inlaid in the light-transmitting resin strip, and then connected to the automatic machine to produce the light guide point to make a flexible light guide strip. The light strip is inlaid on the edge of the light guide strip, and then connected to the automatic double-material machine. Enter the two-material extruder to extrude the light-transmitting resin and the light-reflecting resin at the same time, and wrap the flexible light guide strip inlaid with the LED flexible light bar. The entire connection is automatically made into a panel light, with the diffused light-transmitting resin surface tightly attached to it. The light emitting surface of the light guide strip is formed with a light exit surface, and the light emitted by the LED enters the light guide strip, and under the action of the light guide plate and the reflective resin, it is uniformly emitted from the outer light-transmitting resin layer through multiple reflections and refraction.
