Light-emitting diode (LED)-exposed waterproof perforated lamp string and manufacturing process thereof

Abstract

The invention provides a light-emitting diode (LED)-exposed waterproof perforated lamp string and a manufacturing method thereof. The LED-exposed waterproof perforated lamp string is formed by combining LED lamps, printed circuit boards (PCBs) and anti-ultraviolet (anti-UV) polyurethane (PU) wires together in a welding mode and an epoxy resin glue embedment mode and solidifying at the high temperature of between 50 and 60 DEG C. The problem that modified epoxy resin and polyvinyl chloride (PVC) cables cannot be firmly adhered and the problem of waterproof performance treatment are radically solved. When the LED-exposed waterproof perforated lamp string is actually used, a plurality of perforated lamps are connected together by a parallel circuit according to a certain rule; the LED-exposed waterproof perforated lamp string has the advantages of simple structure, low cost, long service life, large light-emitting angle, low light attenuation, uniform aperture, low power consumption, energy conservation and environment friendliness, is stable in work and safe in use and is driven by direct current (DC) the constant voltage of 5V; and a special bayonet design is adopted, and the perforated lamps are directly mounted after being perforated, so that mounting cost is lowered, the LED-exposed waterproof perforated lamp string is convenient to maintain, and various boards can be used after being perforated. The perforated lamps are designed in a bidirectional disassembling and assembling separated mode, so that the perforated lamps are easier to maintain and have wide application prospects.

Description

technical field [0001] The invention relates to an LED lamp string, in particular to an LED exposed waterproof perforated lamp string with good waterproof function and display effect and a manufacturing process thereof, belonging to the technical field of LED lighting. Background technique [0002] LED (Light Emitting Diode), also known as light-emitting diode, is a solid-state semiconductor device that can directly convert electricity into light. The heart of LED is the wafer of a semiconductor, and one end of wafer is attached on a bracket, and one end is negative pole, and the other end connects the positive pole of power supply, and whole wafer is encapsulated by epoxy resin. Semiconductor wafer is made up of two parts, and a part is P-type semiconductor, and hole occupies an leading position in it, and the other end is N-type semiconductor, and here mainly is electron. When these two kinds of semiconductors are connected, a "P-N junction" is formed between them. When t...

AI Technical Summary

Problems solved by technology

[0004] Due to the structural design, waterproof performance treatment, and complicated installation of the existing traditional light sources (neon lights, LED modules, etc.), especially the reason why the modified epoxy resin and PVC cables cannot be firmly bonded and the waterproof performance treatment problem , when used outdoors, the waterproof performance is poor, which will affect the service life of the LED lamp, and even cause electrical safety accidents
