PURPOSE: A lighting device is provided to prevent a damage of a connection pin by forming a guide projection part of a light emitting module which protrudes toward a mainboard more than toward the connection pin. CONSTITUTION: A mainboard(100) comprises a connection terminal and a combining part. A connection terminal(130) outputs a driving signal for generating the light to the outside. The combining part is separated from the connection terminal. The connection pin is coupled to the connection terminal and is applied with a signal from the main board. The guide projection part is inserted into the combining part. Guide projection parts(330, 340) protrudes toward the mainboard more than the connection pin.
