In order to be recognized by the main controller, each smart LED light body must be implanted with a smart chip or circuit board that can distinguish an independent address to each smart LED light body before being assembled into a whole light string. Moreover, each smart LED Lamp beads only give a single address, and cannot be sorted at the same time and achieve the effect of single-point control of color
In some applications that require sequencing, such as the layering of Christmas tree LED decorative lights and LED water pipe lights, it is impossible to generate rich sequences and random point-controlled color changes

Embodiment Construction
[0025] The present invention will be described below in combination with specific embodiments and with reference to the accompanying drawings.
[0026] A method of programming address codes for point-by-point control of string-type decorative lamps using external signals. On a two-port lead frame, the single control chip driven by the signal loaded by the dedicated power line and the RGB three-color LED lamp bead are bonded with metal wires. The single control chip of each intelligent LED lamp body contains an independent The identification code is the address code of the single control chip itself. It is a string of 10-bit address codes in binary combination. The metal layer fuse is used to express 0, and the metal layer fuse is blown to express 1. The metal layer fuse is blown. It is realized under the action of pulse current or heat energy emitted by metal test probes or lasers.
[0027] The main controller controls multiple series or / and parallel connected smart LED light...

The invention discloses an address code arrangement method for carrying out point-by-point control on a string light type decoration light by using an external signal. The string light type decorationlight is an intelligent LED light body combination comprising a monomer control chip. The address code arrangement method is characterized in that the address codes of at least two bits of the monomer control chip are designed as a front zone and a rear zone independent of the front zone, wherein the address code of the rear zone is used for sequentially positioning a single light body; the address code of the front zone is used for carrying out random single-point control color execution on a plurality of light bodies under a same address for sequence positioning; when a control signal protocol code of a main controller is transmitted to the light body, an internal logic line of the monomer control chip automatically recognizes the address codes of the at least two bits as independent address codes of the front and rear zones; and the main controller carries out control according to the address codes separately defined by the front and rear zones. The method is simple and practical;and the light bodies are designed as two independent address codes, so that the decoration lamp has the prominent effects of being layered or generating rich sequences and randomly controlling the color change.
Description
technical field [0001] The invention relates to an LED lamp body, in particular to an address code programming method for controlling a lamp string decorative lamp point by point by using an external signal. Background technique [0002] Urban lighting and holiday decoration lights have been upgraded from the embellishment effect of only flashing lights to intelligent applications such as using external signals to control demonstration patterns to present text information. The directional color control of the lamp bead is completed by using the data protocol code composed of the address code and the RGB three-primary color gray scale to correspond to the address code of the corresponding LED lamp bead monomer. The LED lamp bead monomer is a single control chip driven by a dedicated power line loaded with a signal on a two-port lead frame and the RGB three-color LED lamp bead is bonded with a metal wire, which integrates control and light emission. The intelligent LED lamp b...
