Abstract:
1. An LED lighting device inlaid on a ceiling, wherein the ceiling is divided into a plurality of lattices, and a plurality of vacated frames are formed on the lattices for being inlaid with a plurality of LED modules respectively; a connector and a matrix of LEDs are installed on the LED modules, wherein the matrix of LEDs comprises at least one row of LEDs and the LEDs of each row are serially connected; a screw hole is formed on upper edge and lower edge of the LED modules respectively; a plate is installed on upper edge and lower edge of the vacated frames respectively, and a screw hole on the plate is exposed along the edge of the vacated frames; a power line, an AC/DC converter, a current stabilizer and a resistor are installed on the plate; the screw hole on the plate corresponds to the screw hole on the LED module, such that when the LED module is inlaid within the vacated frame, a screw is used to pass through the two screw holes to fix the LED module and the plate; an AC power is inputted through the power line to the AC/DC converter for being converted into a DC power, and then the DC power passes through the current stabilizer, the resistor, and the connector for being inputted to two ends of each row of the LEDs.
