PURPOSE: An ultra slim optical joystick with a light device and a mobile device having the same is provided to improve the exterior thereof by combining a lighting device to the optical joystick module. CONSTITUTION: A housing is composed of an IR(Infrared) zone(22) and a lighting zone(24). A holder(30) is combined to the housing and has a receiving space. A light source(40) projects light to the IR zone. The imaging member(50) installed in the holder inside condenses the light. A light receiving sensor calculates a changed phase value by receiving the condensed light through the imaging member. A lighting member(70) installed in the PCB(Printed Circuit Board) projects light to the lighting zone. The lighting zone includes a penetration part in the central part of the housing. |
