Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a lighting control device and a lighting control system for supporting maintenance management of lamps and lighting fixtures.

[0002]

2. Description of the Related Art Conventionally, in stores such as convenience stores, offices, gymnasiums, factories, etc., automatic control of appropriate illuminance, free setting of lighting range according to layout, daylighting lighting and time schedule control can be performed. In addition, the introduction of lighting control devices that realize energy saving and labor saving in facility management is increasing.

[0003] Automatic control of the proper illuminance in this lighting control device will be described.

FIG. 6 is a graph illustrating the relationship between the lighting time and the illuminance for explaining the principle of proper illuminance control.

[0005] In the figure, the horizontal axis represents the lighting time of the fluorescent lamp apparatus, and the vertical axis represents the illuminance. This figure shows a change in illuminance when proper illuminance control by the illumination control device is not performed. At the initial stage of lighting of the fluorescent lamp, the illuminance is considerably higher than the designed illuminance. However, the illuminance decreases as the lighting time elapses. The cause is a decrease in the amount of light emitted from the fluorescent lamp itself and dirt on the lighting equipment, that is, a reduction in the efficiency of the equipment due to the dirt on the reflector and the lamp. However, in the first half of the life of the fluorescent lamp, the illuminance is sufficiently higher than the design illuminance. When the reflector and the fluorescent lamp of the lighting fixture are cleaned at such a stage, the illuminance increases again, and then gradually decreases from the rising position. Thereafter, when an appropriate period has elapsed, when the reflecting plate and the fluorescent lamp of the lighting fixture are cleaned again, the illuminance temporarily increases, and the illuminance decreases from the rising position. Then, it reaches the average life time. At this point, it is common to replace the fluorescent lamp.

In FIG. 6, the shaded area above the design illuminance is the amount of energy saving that can be achieved by performing proper illuminance control by the illumination control device. That is, the lighting control device has a control function of supplying a programmed dimming signal to the dimmable fluorescent lamp fixture. Then, the energy consumption corresponding to the brightness exceeding the design illuminance is suppressed by schedule control, feedback control by an optical sensor, or control by a combination of these.

Next, the time schedule management by the lighting control device will be described. This management automatically switches the lighting status according to the schedule of the day.Before starting work, the lighting level should be lower than the proper lighting level, during working hours the lighting level should be proper, the lighting should be stopped during lunch breaks, and the lighting should be stopped during overtime hours. By turning off the lights, the unnecessary lights are stopped to save energy.

[0008] Further, the external light use control will be described.
In this control, the illuminance is controlled in accordance with the external light amount within an operation level range of the optical sensor arbitrarily set using the optical sensor.

In addition, various controls such as group / pattern control, zone control, and forgetting-to-turn-off control for presetting the optimal lighting state according to the place and application are performed.
