Problems solved by technology

However, it is difficult to completely cover the bare lamp pins with this process (that is, it is difficult to achieve a sealing effect), especially the two lamp pins are quickly corroded, resulting in insulation damage or even breaking off, which leads to lamp failure. , Seriously affect the use and life of the product. In addition, there are also shortcomings such as the consistency of the appearance of the product is difficult to control and affects the appearance.

Abstract

The invention discloses a manufacturing method of an LED lamp string, comprising the following steps of: sealing an LED unit in a way of injecting glue to a mould; placing the LED unit into a cavity which is encircled by an upper concave cavity of an upper mould and a lower concave cavity of a lower mould and can completely contain the LED unit and a lead head connected with the LED unit, and then injecting the glue to the cavity so that thermoplastic resin colloid seals two exposed lamp bases of the LED unit and the connection positions of the two exposed lamp bases and leads. The invention not only meets the functions of electric insulation and seal, but also greatly enhances the manufacturing efficiency of the LED lamp string, prolongs the service life of the LED lamp set and has attractive effects of very good product appearance consistency and the like.

Description

technical field [0001] The invention relates to a manufacturing method of a decorative lighting fixture, in particular to a manufacturing method of a completely sealed LED lamp string. Background technique [0002] LED (light emitting diode in English) is a light-emitting diode, which is made of electroluminescent semiconductor materials. LED has low voltage, high efficiency, good monochromaticity, strong applicability, good stability, and fast response time. Short, long life, no pollution to the environment, etc.; LED uses low-voltage power supply, and the power supply voltage is between 2-24V, which is more secure; LED consumes 80% less energy than incandescent lamps with the same light efficiency; each unit LED It is very small and can be made into lighting fixtures of various shapes, and is suitable for different environments; because LED has the above excellent characteristics, it is widely used in decorative lighting and other fields. For example, LED light string is a...
