no. 1 example ）

[0037] In a first embodiment, a lighting system includes a lighting control device and at least one lighting load. figure 1 An example of a system including a plurality (for example, two) of lighting systems (A) and an operation display unit 3 is shown.

[0038] Such as figure 1 As shown, each lighting system (A) includes a lighting control device 1 and a plurality (for example, four) of lighting loads 2, each of which is capable of tinting to adjust the correlated color temperature of light emitted therefrom, and Able to dim. Each lighting control device 1 of the lighting system (A) is connected to the operation display unit 3 through a communication line ( L1 ), and is configured to communicate with the operation display unit 3 .

[0039] In a lighting system (A), a lighting control device 1 is connected to a lighting load 2 through a communication line ( L2 ), and is configured to communicate with the lighting load 2 . Each lighting load 2 includes a plurality of light s...

[0080] Such as Figure 11 As shown, in addition to the structure of the first embodiment, the lighting control apparatus 1 of the second embodiment is further provided with a human detector (for example, a motion sensor) 1c. For clarity, elements of similar kind are assigned the same reference signs as shown in the first embodiment.

[0081] The human detector 1 c is configured to detect the presence or absence of a human in an installation space (for example, an office) of the lighting load 2 to transmit the detection result to the controller 1 a of the lighting control device 1 . The controller 1a is configured to perform the following control based on the detection result of the human detector 1c.

[0082] When a person is in the office, similarly to the first embodiment, the controller 1a performs timer control according to the schedule information, thereby adjusting the correlated color temperature and horizontal illuminance in the office obtained from at least one corre...

[0090] Such as Figure 12 As shown, in addition to the structure of the first embodiment, the lighting control apparatus 1 of the third embodiment is further provided with a brightness sensor (brightness sensor) 1d. For clarity, elements of similar kind are assigned the same reference signs as shown in the first embodiment.

[0091] The lighting load 2 of the lighting system (A) in the third embodiment is installed in an office with windows. Therefore, the illuminance in the office changes in response to incident light such as sunlight from the outside.

Abstract

Alighting system includes a lighting load and a lighting control device. The lighting control device is configured to adjust a light output of the lighting load to a first light output corresponding to a first correlated color temperature and a first illuminance in a first time slot, and to decrease the light output of the lighting load up to a second light output corresponding to a second correlated color temperature and a second illuminance with the passage of time in a second time slot after the first time slot.

Description

technical field [0001] The present invention relates to a lighting system (a lighting system for correlated color temperature and dimming control) configured to adjust the light output of a lighting load to a light output corresponding to a predetermined correlated color temperature and illuminance, and to equip the lighting system with lighting control equipment. Background technique [0002] Japanese Patent Application Publication No. 2000-252084A (hereinafter referred to as “Document 1”) discloses a lighting system configured to generate a light environment suitable for a person's biological rhythm such as circadian rhythm throughout the day. The lighting system includes lighting fixtures capable of emitting high-intensity light, medium-intensity light, and low-intensity light, and a control device configured to perform lighting control of the lighting fixtures. The control device performs lighting control of the lighting fixtures, thereby allowing the lighting fixtures ...
