PURPOSE:To prevent the malfunction caused by high-frequency noises by locating a lighting device below, locating a reception section receiving a control signal and a control device controlling the turning on or off and dimming above, and arranging a shield plate between both devices. CONSTITUTION:A receiver 25 receiving a control signal and a control device 22 turning on or off and dimming a lamp based on the control signal are located above a lighting device 16, and the device 22 and the device 16 are vertically arranged in stratification. The receiver 25 is faced to a reception hole 3a opened on the side face of a chassis section 2. The receiver 25 does not receive the visible light and infrared light radiated from the lamp, and malfunction is prevented. A shield plate 32 is arranged above the circuit board 17 of the device 16 via an insulating face, and the malfunction caused by high-frequency noises generated from electronic parts of the devices 16, 22 can be prevented. |
