PROBLEM TO BE SOLVED: To provide an illumination equipment in which a remote control light receiving section causes malfunction and transmission fault of an optical signal due to a light of a fluorescent light by selecting a light receiving direction of the remote control light receiving section downward in the vertical direction and arranging the location in a torus of a round fluorescent light toward the base metal. SOLUTION: A ceiling mount illumination equipment is made up of a round fluorescent light 3 arranged concentrically to a lower face of a fixture main body 10, a signal section 10a and a remote control transmitter. The signal section 10a is provided with a light receiving section 1 receiving a remote command signal, a local operation switch 6a, a dimmer variable resistor 6b and an inverter lighting section or the like. The light receiving direction of the light receiving section 1 is selected in the vertical direction downwards so as not receive the light from the fluorescent light and the light receiving section 1 is arranged in a direction with minimum luminous quantity of the fluorescent light towards a base metal 4. Furthermore, a light shield rib is provided around the light receiving section 1. The light receiving section 1 and a reception signal processing circuit are arranged at a location part from an inverter lighting circuit section to avoid an electromagnetic noise. Thus, the control reliability of a remote control transmitter is improved. |
