Novel parallel string lights

Abstract

The invention relates to novel parallel string lights. A plurality of LEDs are arranged in parallel to form the string lights, the LEDs are electrically connected with a first wire and a second wire,one end of the first wire is communicated with one end of the first LED, and one end of the second wire is communicated with the other end of the last LED. The novel parallel string lights have the beneficial effect that voltage and current of all LED lamps of the overall string lights are coincident, and therefore the luminance is unified, wherein the number of the lamps from one to N can be determined according to the power of a power supply source. The parallel LED string lights in the connecting method are better than tandem type LED string lights (after the number of lamps in the tandem type LED string lights exceeds 50, the front and back lighting intensity has obvious differences, and the overall set of LED string lights does not light when one LED lamp bulb in one set does not light). According to the parallel string lights, other LED lamp bulbs cannot be influenced when one LED lamp bulb does not light, the production process is simple, the production cost is low, and the novel parallel string lights are relatively suitable for decorative LED string lights.

Description

technical field [0001] The invention specifically relates to a novel parallel lamp string. Background technique [0002] Traditional parallel LED light string: the positive and negative poles of the power supply are all connected to the first LED light of the light string. Due to the problem of voltage drop, the LED lights near the front of the power line will be brighter, and the LED lights will be darker as they go further. , After more than 30 LED lights, the brightness of the front and back of the light string will be very different. If you want to increase the power supply voltage to solve this voltage drop problem, the LEDs at the front of the light string will be burned quickly. [0003] "DCTD protocol LED" is also called "LED with IC chip", including monochrome LED with IC chip, RGB LED with IC chip and W+RGB LED with IC chip. Contents of the invention [0004] The object of the present invention is to provide a new type of LED lamp string with parallel arrangeme...
