Abstract

PURPOSE: To make stable the feeling of hens in the hen house such as poultry farm, by similar change of incandescent lamps for illumination and distinguish to that of sun rays.
CONSTITUTION: The power control unit 4 consists of the timer circuit 41 operated in synchronizing with the voltave change of AC power supply 1, timer circuit 42 operated with the instruction of the operation mode set unit 5, comparator 43 comparing the output value of the timer circuits 41 and 42, and controlled rectifying element 44 closed with the signal of the comparator 43. The input terminal of the power control unit 4 is connected to the power supply 1 via the switch 3' and the output terminal is connected to the incandescent lamps 2. In the poultry farm using the incandescent lamps 2 as lighting equipment, the light increasing state can be simulated to dawn, the full power supply is noon and light decreasing state is twilight. Very stable lighting environment the same as natural luminous intensity can be offered to hens, allowing to make ease the feeling of hens.
