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

Embodiment 1

[0017] Embodiment 1: with reference to attached figure 1 . A light-transmitting LED waterproof lamp group. A plurality of LED lamps 1 are connected in series to form an LED lamp group. The light source of the one or more LED lamps 1 is composed of one or more LED2 arrays. The plurality of LED lamps are covered with PVC paste. It is sealed and wrapped into a light-transmitting and waterproof lamp group, and a gap-free sealing structure is formed between the LED light source and the PVC paste. One or more LED2 series packaged finished products. The manner and structure of one or more LEDs 2 arranged to form the LED light source are prior art, and will not be described here. The drive circuit 3 used to drive the LED light source is a prior art, and will not be described here. The air-gap-free sealing structure means that there may be a peeling gap between the PVC paste and the coated device (LED light source, drive circuit, control chip, etc.), but the peeling gap is a sealed ...

Embodiment 2

[0018] Embodiment 2: On the basis of Embodiment 1, the LED lamp itself includes an LED driving circuit and is sealed and covered by PVC paste.

Embodiment 3

[0019] Embodiment 3: On the basis of Embodiment 1, the LED lamp itself includes an LED driving circuit and a control chip and is sealed and covered by PVC paste.

Abstract

The invention relates to a light-transmitting LED (light-emitting diode) waterproof lamp group and a manufacturing method thereof. The light-transmitting LED waterproof 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 LED waterproof 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 PVC (polyvinyl chloride) thickener to form the light-transmitting LED waterproof lamp group. The light-transmitting LED waterproof 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 light-transmitting LED waterproof lamp group is low in processing cost, short in producing period and high in processing efficiency; 3, the shape of the light-transmitting LED waterproof 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 waterproof lamp which not only has good anti-ultraviolet function and excellent weather resistance, but also can be independently used as an LED light source lamp housing, and can work outdoors and underwater for a long time without water vapor infiltration. The assembly and the manufacturing method belong to the field of outdoor waterproof lamp manufacturing. Background technique [0002] 1. CN102454908A, titled "LED Exposed Waterproof Light String and Manufacturing Method of the Light String", is to use welding and epoxy resin glue potting to combine LED lights, PCB circuit boards, and UV-resistant PU leads. ℃-60℃ high temperature curing and become. It fully solves the problem that the modified epoxy resin and PVC cables 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. ...
