Document Type and Number:
Japanese Patent JP2634084
Kind Code:
B2
Abstract:
PURPOSE:To perform delicate illumination control by providing load control terminal turning on or off or dimming an illumination fixture based on the preset illumination state as appropriate. CONSTITUTION:When the outdoor is changed from the bright state to the dark state in the evening, an external light detecting terminal 1 transmits the dark signal to a transmission line 2, and a main operation panel 3 having received this dark signal transmits the night signal to the transmission line 2 because the present time is before T1 set by a timer section 4. An on/off-load control terminal 6a and a dimming load control terminal 6b receive this night signal and hold it. When a human body sensor 8a detects a person under this condition, the terminal 6a turns on an illumination fixture 7a according to the illumination state 'ON' set by an illumination state setter 9a in response to the state of 'night' and 'presence of person'. When the sensor 8a detects no person, it turns off the illumination fixture 7a according to the illumination state 'OFF' corresponding to the state of 'night' and 'absence of person'. The illumination fixture 7a is turned on or off or dimmed, and delicate illumination control in response to various states is performed.
