Abstract

A light emitting diode light strip unit structure is provided. The light emitting diode light strip unit structure includes an illuminating light strip unit which can be connected with an external power source and receive an external control signal independently as a light source. A plurality of illuminating light strip units are assembled and electrically connected with each other. Power supply voltage contacts and working voltage contacts of the illuminating light strip units are electrically connected with the power source to get working electricity. When grounding contacts of the illuminating light strip units complete the ground connection, signal output contacts and signal input contacts of the illuminating light strip units are electrically connected. One of the signal input contacts of the illuminating light strip units is predetermined to receive the control signal to form various types or forms (area) of light sources.
