Paster type LED flexible light strip

Abstract

The invention discloses a paster type LED flexible light strip, and belongs to the field of illumination. The light strip comprises a core wire, a plurality of flexible circuit boards and a plurality of paster type LED chips respectively arranged on the flexible circuit boards, wherein an accommodating groove is formed in the core wire in the length direction of the core wire; the flexible circuit boards are sequentially arranged in the accommodating groove. The paster type LED flexible light strip disclosed by the invention is characterized in that the accommodating groove is filled with a translucent silicone layer; the translucent silicone layer covers on the flexible circuit boards and the LED chips. According to the paster type LED flexible light strip disclosed by the invention, the structures are arranged, so that the paster type LED flexible light strip is thin, materials and the cost are effectively saved, the flexibility is good, the illuminating effect is good, the rate of finished products is high, and requirements of a producer and requirements of a user can be well met.

Description

technical field [0001] The invention relates to the lighting field, in particular to a patch type LED flexible light strip. Background technique [0002] With the continuous improvement of people's living standards, the use of LED light strips is becoming more and more popular. In the existing technology, the silicone light strip is to produce a silicone sleeve first, and put the flexible circuit board welded with the SMD LED chip into the sleeve to form the SMD LED flexible light strip. The circuit board is inserted in the process It is easy to be damaged, and in some cases, silica gel is injected into the sleeve after completing the above steps. The production efficiency of the silicone light strip with this structure is low, it is difficult to guarantee the quality, and it is easy to form air bubbles. If the length is too long, it is impossible to complete the glue filling process. In addition, because all of them are made of silica gel, the mechanical strength is poor, ...

Problems solved by technology

In actual use, the covering layer and core wire of this product are both made of PVC material, and the covering layer is directly extruded on the basis of the core wire through an injection molding machine. The materials are different. The coating layer is not combined with the surface of the packaging silicone in the insulating seat cavity of the chip. The inner surface of the coating layer forms a reflective surface on the LED chip. After the light is emitted from the LED chip, part of it is reflected back through the inner surface of the
