This invention relates to an LED lamp device which is compatible with a socket for a general fluorescent light, a halogen light or an incandescent light and can be manufactured through miniaturization at a low cost. A lamp with LEDs, powered by an alternating current, can be configured with a simplified rectifier circuit without a dedicated circuit such as an SMPS through the control over the number of LEDs. For the above purposes, the invention comprises: a luminescent body wherein plural LEDs are arranged as light devices in a portion of the base where each component is installed; a circuit unit that is installed at the base of the luminescent body and electrically or electronically connected with each LED, converts AC power received from the outside into DC power to enable each LED to emit light; and terminal units that are installed at one or both ends of the luminescent body to receive and input the external AC power to the circuit unit. Since a light-transmitting material is coupled to the base at the portion where the LEDs are arranged, the lights emitted from the LEDs are diffused through the light-transmitting material in the luminescent body.
