<P>PROBLEM TO BE SOLVED: To provide an illuminating device for accurately detecting existence of a detected object without affecting constraint on a structure and appearance. <P>SOLUTION: The illuminating device includes a light source part 1 having a plurality of LEDs 10, a sensor part 2 having a wave-carrying part carrying an energy wave of a desired frequency and a wave-receiving part receiving a reflection wave with the energy wave carried from the wave-carrying part reflected at an object, and outputting a detection signal by detecting an existence of a moving body based on a difference between frequencies of the wave-carrying and -receiving parts, a control part 3 controlling lighting of the light source part 1 in accordance with the detection signal from the sensor part 2, and a power supply part 4 fitted outside a detection area of the sensor part 2 and supplying lighting power to the light source part 1. The sensor part 2 is fitted at an opposite side of the light source part 1 from a direction of light irradiated from that 1. <P>COPYRIGHT: (C)2010,JPO&INPIT |
