Abstract

A SMT LED light string which the ICs with IDs are embedded in the light beads; wherein the light string is formed by connecting a plurality of SMT LED light beads which the IC control chips with IDs are set inside. All of the corresponding IC control chips with IDs for the SMT LED light beads can be controlled because the IC control chips with IDs are set in the SMT LED light beads. Therefore, the stable and orderly flashing can be achieved, and the lighting effects such as the line-up, the progression, and the chasing . . . , etc. can also be made. No matter for a monochrome light string or a colored light string, the effective control can both be achieved to make the various lighting effects because the IC control chips with IDs are set in the SMT LED light beads.

Claims

1. A SMT (RGB) LED light string, wherein a light string is formed by connecting three or more SMT LED light beads with IDs, wherein the IDs that are set in the SMT LED light beads as orderly arranged identifications;

wherein an RGB light source and a control chip are both set in each of the SMT LED light beads to form an LED light;

wherein the SMT LED light beads are connected together to form the light string and each of the SMT LED light beads includes a control chip embedded therein; and

wherein a control IC is connected serially in front of the light string to pair with the control chips of the SMT LED light beads to control lighting of the SMT LED light beads.

2. The SMT (RGB) LED light string according to claim 1, wherein the light string is formed by connecting a plurality of SMT LED light beads with IDs, and the IDs are formed by a ID composition of three, four, five, . . . N.

4. The SMT (RGB) LED light string according to claim 1, wherein the connection of the SMT LED light beads is serial connection, parallel connection, or serial-parallel connection.

3. (canceled)
