Dosing technology type series -type LED light source

Abstract

The invention relates to an embedding crafting series and parallel LED light source. In the prior art, the LED is inserted in a circuit board to achieve sealing and waterproof effect, or the LED is sealed in a PVC pipe after being wired, or the LED light is used by connecting the lights in series through wires, however, the prior art has the disadvantages of complex process, non-flexibility and unchanged shape and size. The invention adopts an embedding method for sealing a metal joint between an LED lead foot and a wire, including some circuit parts. A hole-opening embedding strip comprises a bracket for fixing a mould cup, a plurality of locating holes and mould cups. The LED light bodies are respectively inserted into the mould cups, and injected and sealed by an injector provided inside with epoxide resin (silicon gel). The sealed light bodies can be directly connected with 110V or 220V alternating current (commercial power) after being connected with rectifier filters, and then can be hung on a building or a branch to be served as decorative lights, or arranged in array in an illuminated advertisement box to form patterns or characters. The LED light source has the advantages of simple technique, wide application range, safety and reliability, low production cost, high use value and favorable implementation.

Description

technical field [0001] The invention belongs to the technical field of optoelectronics, and in particular relates to a series-type LED light source of potting process type which can be safely used indoors and outdoors. Background technique [0002] LED is a new type of semiconductor solid light source, which has the advantages of energy saving (high luminous efficiency), bright color (various and bright colors), long life (lifetime of more than 100,000 hours), environmental protection (no glass, no poisonous gas), etc. , so LEDs replace traditional light bulbs and are used in various lighting and lighting decorations to become an inevitable trend. [0003] However, since the driving voltage of a single LED is very low (less than 3.6V), it is more convenient to apply if the LEDs can be connected in series to withstand high voltage, and the current can be reduced. [0004] How to use LEDs in series, some existing methods are: [0005] 1) The circuit board (PCB) is plugged wi...

Problems solved by technology

[0005] 1) The circuit board (PCB) is plugged with LEDs, and then sealed and waterproof. The disadvantage is that it cannot be bent, and the shape and size cannot be changed;

[0006] 2) The LED is connected and sealed in a PVC tube, but at the same time there are problems such as complex process, not easy to bend, and cannot change shape and size;
