Abstract:
PROBLEM TO BE SOLVED: To have light emission intensity distribution of a fluorescent lamp, to radiate light from low light intensity to high light intensity, and to switch between it and an incandescent lamp. SOLUTION: Driving current of RGB three-color LED 12 is controlled so that output current of the illuminance sensor 11 has the same current value as the output current of the illuminance sensor 11 under the fluorescent light of 3 to 55000 Lx while the intensity ratio of R:G:B of the three-color LED 12 is kept at 100:94:43, and each acquired driving current value is stored in a light emission intensity control section 18. When the illuminance sensor is inspected, by driving the three-color LED 12 based on each stored driving current value, each LED is made to emit light having the same light emission intensity distribution as that of the fluorescent lamp and substantially the same illuminance as that of the fluorescent lamp. Therefore, the fluorescent lamp light source for inspection is switched to the RGB three-color LED light source to simplify the constitution, and the light from low light intensity to high light intensity can be radiated. Switch with the incandescence lamp 14 can be performed by drawing out a light shielding plate 17 provided with the RGB three-color LED 12. COPYRIGHT: (C)2009,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a testing device for a human body detection sensor capable of testing whether there is a required detection region and sensitivity with respect to the human body detection sensor. SOLUTION: In the testing device for the human body detection sensor for detecting the presence of a human body in a predetermined detection region, when a constant-temperature body, having a predetermined temperature difference to an ambient temperature, is moved relative to the human body detection sensor and an infrared light radiated from the constant temperature body passes through a plurality of openings disposed on an infrared light shield; a determination means compares the output value of the human body detection sensor with a first and a second thresholds; and if the output value is the first threshold or higher and the second threshold or lower, the determination means outputs to the output means a determination result, indicating that the human body detection sensor can detect the presence of a human in the predetermined region.

SOLUTION: One ends of a plurality of cylinders 101 are opposed to devices D1, D2, ..., Dn to be inspected in remote control light-receiving units RU1, RU2, ..., RUn, respectively. Light-emitting elements S1, S2, ..., Sn as signal sources are installed on one ends of the cylinders 101, respectively.

SOLUTION: In the solar simulator 1, a controller 12 switching-drives a power switching element 20 according to a predetermined control pattern so that flash light F emitted from a xenon lamp 14 is kept at a target illuminance for a specified period. Thus the current which is released from a capacitor 26 to flow the xenon lamp 14 is controlled. COPYRIGHT: (C)2009,JPO&INPIT
