High-brightness LED flexible neon lamp

Abstract

The invention discloses a high-brightness LED flexible neon lamp. The lamp comprises a long-strip-shaped LED flexible lamp board, a first transparent insulating plastic layer arranged on the periphery of the LED flexible lamp board, a light-transmitting insulating plastic skin coating the periphery of the first transparent insulating plastic layer and a first light blocking wall, wherein a light emitting body is arranged at the top of the skin; light scattering powder is arranged in both the skin and the light emitting body; the first light blocking wall is located at the lower part of the light emitting body and is located on one side of the insulating plastic skin; a flexible circuit board is placed vertically, that is, the flexible circuit board is perpendicular to a light emitting surface where the light emitting body is located, and light emitted by LEDs faces the first light blocking wall; a second light blocking wall is located at the lower part of the light emitting body and is located on the other side of the insulating plastic skin; and the second light blocking wall is lower than the first light blocking wall. The lamp has the advantages of being high in brightness, large in light emitting area, convenient to produce and capable of bending leftwards and rightwards along the light emitting surface.

Description

technical field [0001] The invention relates to the field of decoration or lighting, in particular to an LED flexible neon lamp with high brightness, large light emitting area, convenient production and can be bent left and right along the light emitting surface. Background technique [0002] LED flexible neon lights use insulating plastic shells. Compared with traditional glass tube high-pressure gas discharge neon lights, they can be easily bent, safe and energy-saving, and have a wide range of applications. [0003] The structure of the traditional LED flexible neon light can be referred to the patent number: 200410032066.5. Its structure is as follows: a plurality of in-line LEDs are connected in series through wires, and a long strip of insulating plastic core wire is set, corresponding to the LED in the insulating plastic core wire. Set a through hole at the position, insert the LED into the through hole, and then cover the insulating plastic core wire with an insulati...

AI Technical Summary

Problems solved by technology

[0006] The previous technology used in-line LEDs, which required manual or semi-automatic welding, with low production efficiency and high cost. With the improvement of welding technology and LED packaging technology, it is now turning to SMD LEDs to be welded on long strips of flexible LEDs. The circuit board is made into a lamp board light source, which can be produced by a high-speed chip mounter and a reflow soldering machine. The production efficiency is high and the cost is low, but it also brings some problems because the long flexible circuit board cannot be bent along the width direction. Therefore, after placing the lamp board in the flexible neon lamp, the bending of the lamp body is limited, and the lamp body cannot be bent left and right along the light-emitting surface. However, when the lamp body is installed, it is generally bent left and right along the light-emitting surface
