摘要： A variable color luminaire is arranged for controlling a plurality of light sources of different emission colors to be at predetermined dimming levels by means of dimmers, performing a comparison operation to obtain a quantity-of-light ratio and a reference quantity-of-light ratio from detection signals with respect to light outputs of the light sources detected by detectors, and subjecting the light sources to a quantity-of-light correction by means of a corrector according to results of the comparison operation so as to attain a blended color light as set, whereby the resultant blended color light can be prevented from deviating from the set blended color light even when dimming quantity of the respective light sources is close to upper and lower dimming limits.

摘要： In order to suppress cost of an initial investment by a user and running cost to the user to a low extent while substantially constantly maintaining an apparent illuminance, and further, to realize resource saving, in a case of using a fluorescent lamp FHF 32 as a discharge lamp La, a lamp supply power is started to be supplied from a value lower than 45 W as rated electric power at an initial period of an operation of the discharge lamp, a light adjustment signal is changed in response to an accumulated lighting time so that the lamp supply power can be a value higher than 45 W as the rated electric power on and after a rated lifetime of the discharge lamp La, whereby the lamp supply power (output of an inverter circuit 2) is adjusted. In the fluorescent lamp FHF 32, a light/electric power ratio becomes substantially constant when the lamp supply power is 41 W to 55 W, and accordingly, a light quantity is increased without impairing light emission efficiency of the discharge lamp La, and as a result, the apparent illuminance can be maintained substantially constantly.
