The present invention provides an LED lighting device inlaid on a ceiling. The ceiling is divided into a plurality of lattice by a matrix of metal strip, plastic strip or wood strip, a matrix of LED are installed on the lattice; an AC power is inputted through a power line to an AC/DC converter for being converted into a DC power, and then the DC power passes through a current stabilizer, a resistor, a connector for being inputted to two ends of each row of the LEDs; LEDs of each row are serially connected.Another embodiment of the present invention is to divide a ceiling into a plurality of lattice by a matrix of metal strip, plastic strip or wood strip, a plurality of vacated frame are formed on the lattice for being inlaid with a plurality of LED module respectively; a connector and a matrix of LED are installed on the LED module; a plate is installed on the upper edge and lower edge of the vacated frame; a power line, an AC/DC converter, a current stabilizer and a resistor are installed on 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, the connector for being inputted to two ends of each row of the LEDs; LEDs of each row are serially connected.
