PURPOSE: An indoor door handle is provided to easily grasp a position of a door by a user in a dark place because a light source of a handle automatically emits lights when human beings approach to the handle or a power is cut off. CONSTITUTION: An indoor door handle comprises a lever body(100), a handle(200), a light source device, a window member, a power unit, a motion sensor(600), an illuminance sensor, and a controlling unit. The lever body comprises a connection groove. The connection groove is connected to a standardized connection protrusion formed on a locking device body. The handle is formed in a direction perpendicular to an axial direction of the lever body and comprises a plurality of through-holes. The light source device is mounted in a circuit substrate installed in an inner side of the handle. The window member is formed with transparent materials in order that the lights of the light source device can be transmitted to outside through the through-holes of the handle. The window member prevents foreign materials flowing into the inside of the handle through the through-holes. The motion sensor senses ambient motions, thereby outputting sensing signals. The illuminance sensor senses ambient illuminance flowing into the window member, thereby outputting the sensing signals.
