Light-transmitting led outdoor lamp group and its manufacturing method

Abstract

The invention relates to a light-transmitting outdoor LED (light-emitting diode) lamp group and a manufacturing method thereof. The light-transmitting outdoor LED lamp group is provided with a good ultraviolet resisting function and an excellent weather resistance performance, can serve as an LED light source shell independently and can work outdoors and underwater for a long time without moisture permeation. The light-transmitting outdoor LED lamp group is formed by a series of connection of a plurality of LED lamps. Light sources for the one or a plurality of the LED lamps are formed by one LED or arrangement of a plurality of LEDs, and the one or a plurality of the LED lamps are hermetically coated by a modified PVC (polyvinyl chloride) thickener to form the light-transmitting outdoor LED lamp group. The light-transmitting outdoor LED lamp group has the advantages that 1, the PVC thickener serving as a shell of the LED light source is good in ultraviolet resistance, low temperature resistance and weather resistance and can reach V-2 to V-0 grades in flame retardance; 2, material cost and production cost of products are reduced, and the outdoor light-transmitting LED lamp group is low in processing cost, short in producing period and high in processing efficiency; 3, the shape of the light-transmitting outdoor LED lamp group can be formed differently according to different needs of users, and a technical bias that technicians in the field consider that the PVC thickener cannot serve as an LED lamp group forming material for a long time is basically changed.

Description

Technical field [0001] The invention relates to a light-transmitting LED outdoor lamp that not only has good anti-ultraviolet function and excellent weather resistance, but also can be used as an LED light source lamp shell independently, and can work outdoors and underwater for a long time without water vapor infiltration. The group and the manufacturing method belong to the field of outdoor waterproof lamp manufacturing. Background technique [0002] 1. CN102454908A, the name "LED exposed waterproof light string and the method of making the light string", is to combine LED lights, PCB circuit boards, and UV-resistant PU leads by welding and epoxy resin potting. It is cured at a high temperature of ℃-60℃. It fully solves the problem that the modified epoxy resin and PVC cable cannot be firmly bonded and the problem of waterproof performance. In actual use, a parallel circuit is used to connect several perforated lamps together according to certain rules, and each perforated lam...

AI Technical Summary

Problems solved by technology

[0004] The shortcomings of the above-mentioned background technology: first, when epoxy resin and silica gel are soaked in high humidity or water for a long time, water seepage will occur, resulting in failure and damage of the lamp, and the purpose of long-term waterproofing cannot be achieved; second, epoxy resin When used outdoors with silica gel, there will be yellowing, cracking or separation from the shell, which will cause moisture to enter the light source and cause the light source to fail

Its disadvantages: According to the performance of PVC material, those skilled in the art think that PVC material can only be used as sealing packing, and cannot be independently used as a light source housing
