Embodiment Construction

[0042] Object and feature of the present invention, by following the appended Figure 1 The following description of the preferred embodiment carried out together will make it clear.

[0043] The lighting control system 1 of the embodiment of the present invention is as figure 1 As shown, a lighting control device 2 and a lighting load 3 are provided. The lighting control system 1 such as figure 2 (a) is installed on the ceiling surface C.

[0044]The lighting load 3 is, for example, an LED (Light Emitting Diode: Light Emitting Diode) or a fluorescent lamp, and is turned on by electric power supplied from an AC power supply (not shown), and illuminates a predetermined area A. In addition, as an AC power supply, there is, for example, a commercial power supply (mains power supply) with a voltage of 100V.

[0045] Lighting control devices 2 such as figure 1 As shown, an image sensor 4 , an image processing unit 5 , a storage unit 6 , a light receiving unit (receiving uni...

Abstract

Disclosed is a lighting control device, a lighting control system and a lighting up control device, which achieve both human detection and brightness control by means of a single shooting part. When a person exists in the region, the lighting control device (2) of the lighting control system (1) controls the lighting up of a lighting load (3). In an image sensor (4), the shooting part (41) shoots the region by means of a shooting member arranged with a plurality of light-receiving members. An amplification part (43) amplifies the light-receiving value of each light-receiving member. An adjusting part (44) adjusts gain, thereby the average value of all output values of the amplification part under a first mode becomes a constant value, and the gain is fixed to a standard value under a second mode. An image processing part of the lighting control device detects whether a person exists in the region or not based on the distribution of the output value of the amplification part. When the lighting up device (8) detects that a person exists in the region under the first mode, the lighting up state of the lighting load changes. When the lighting up device (8) conducts dimming control on the lighting load under the second mode, the average value of the output value of the amplification part is contained in a target scope.

Description

technical field [0001] The present invention relates to a lighting control device that controls lighting loads illuminating the area if there is a person in a preset area, a lighting control system including the lighting control device, and a lighting control device used in the lighting control device. Lighting control device. Background technique [0002] Conventionally, various image sensors using CCD cameras or CMOS cameras have been developed and marketed. Person detection that detects the presence of a person in an imaging area using the image sensor is applied in many fields. [0003] As an application example for lighting control, there is known a lighting control system that turns on a lighting load when the presence of a person in an imaging area is detected using a captured image captured by an image sensor. The image sensor is, for example, installed on the ceiling surface (refer to figure 2 (b)). The imaging area at this time is an area vertically downward ...
