したものである。The present applicant uses this as a lighting control device for lighting equipment. "An illuminance detection means that detects the illuminance of the illumination control area and outputs a low illumination detection signal when a low illuminance state that requires illumination is detected, and detects the presence of a person in the illumination control area,
A human body detection means outputs a human body detection signal, and (a) the illuminance detection means outputs a low illuminance detection signal, and on the condition that the human body detection means does not output a human body detection signal, the lighting equipment is turned on at a low brightness. , (b) the illuminance detection means outputs a low illuminance detection signal, and the human body detection means outputs a human body detection signal, the vN lighting fixture is turned on at a high intensity, and (c) the illuminance detection means outputs a low illuminance detection signal. and a control means for turning off the lighting equipment on the condition that the illuminance detection signal is not output, or the illuminance detection means does not output a low illuminance detection signal, and the human body detection means does not output a human body detection signal. He has already proposed what will become of him. According to the above lighting ttiim* position, the above mode (a)
As shown in , the lighting equipment is automatically turned on at low brightness at night when the lighting control area is dark and there are no people there.
The illuminance of the area can be set to the minimum necessary level that can save power and improve crime prevention. or. l-, as in mode (b) above, when the lighting control area is dark and there is a person present, the lighting equipment is automatically turned on at a high intensity to reduce the illuminance of the area to that of the person. It can be set to the level necessary and sufficient for the action. [Problems to be Solved by the Invention] However, in the above-mentioned lighting control device, the illuminance detection means and the lighting fixture are arranged at a large distance from each other due to constraints such as the mechanical configuration of the entire device and the electrical wiring. There are some difficulties. Therefore, the illuminance detection means is forced to detect the illuminance generated in the illumination control area as if both the natural light and the illumination light from the lighting equipment are mixed together. Furthermore, when lighting equipment switches its lighting state, it generally involves a dead lighting period during which the previous lighting state lingers. For this reason, in the conventional lighting control device, when one person leaves the lighting control area that is in a high-intensity lighting state due to darkness and the presence of a person, two human body detection means are activated. Although it immediately outputs the absence of a person, the illuminance detection means does not output a low illuminance detection signal during the relatively high brightness remaining lighting period when the lighting equipment switches from a high brightness lighting state to a low brightness side. Therefore, during the above-mentioned remaining lighting period, - the above-mentioned mode (c) is temporarily applied, and the lighting equipment is turned off once.
Note that after the remaining lighting period has elapsed, the mode (a) described above is entered, and the lighting fixture is lit at low brightness. That is, under low light conditions such as at night. When a person leaves the lighting control area, the five lighting fixtures turn off from high-intensity lighting and then return to low-intensity lighting, causing an inconvenience. The present invention automatically responds to changes in the illuminance of two lighting areas and when people enter and leave the lighting control area, and when providing the lighting control area with an appropriate lighting condition at all times, To ensure that a lighting fixture is switched to low-intensity lighting without turning off once when a person leaves a lighting control area. [Means for Solving the Problem] The present invention provides an illuminance detection means that detects the illuminance of the illumination control area and outputs a low illuminance detection signal when detecting a low illuminance state that requires illumination; a human body detection means that detects the presence of a person and outputs a human body detection signal;
a) Under the condition that the l@ intensity detection means outputs a low illuminance detection signal and the human body detection means does not output a human body detection signal, the lighting equipment is turned on at a low intensity, (b) the illuminance detection means outputs a low illuminance detection signal. on the condition that the human body detection means outputs a human body detection signal! ! ! ! Turn on the bright lights at high intensity. (c) Turn off the lighting equipment on the condition that the illuminance detection means does not output a low illuminance detection signal, or the illuminance detection means does not output a low illuminance detection signal, and the human body detection means does not output a human body detection signal. In the lighting control device for a lighting equipment, the control means includes (d) Il+, regardless of the output state of the intensity detection means, for a certain period of time immediately after the lighting equipment ends high-intensity lighting. The lighting equipment is designed to turn on at a low temperature.

行せしめることができる。According to the present invention, (a) when the illuminance of the lighting control area is low, such as at night, and there is no person in the lighting control area, the lighting equipment automatically turns on at low brightness;
b) If the illuminance of the lighting control area is low, such as at night, and there is a person in the lighting control area, the lighting equipment will automatically turn on at high brightness; When the illuminance of the control area becomes high and there is no person present in the lighting control area, the lighting equipment automatically turns off. Furthermore, according to the present invention, (d) when switching from the mode (b) to the mode (a), that is, under a low illuminance condition such as at night, a person leaves the lighting control area, and! 1: Immediately after the lighting fixture finishes high-intensity lighting in mode (b), the lighting equipment is forcibly turned on at low brightness for a certain period of time. Furthermore, after a certain period of time in this mode (d), the illuminance detection means outputs low illuminance and the human body detection means outputs the presence of a person, so the lighting equipment turns on the low brightness based on mode (a). maintain. That is, according to one aspect of the present invention, the mode (b) is changed from the mode (b) to the mode (
At the time of switching to a), although the lighting equipment exhibits a relatively high residual lighting state in which it switches from a high-intensity lighting state to a low-intensity lighting state, the control means uses the illuminance detection means during this remaining lighting period. It completely ignores the detection results and creates a forced low-intensity lighting state for a certain period of time. Therefore, when automatically responding to illuminance changes in the lighting area and people entering and exiting the lighting area, and always providing an appropriate lighting condition to the lighting control area, it is possible to automatically control the lighting under low-light conditions such as at night. When leaving the area, the lighting equipment can be reliably switched to low-intensity lighting without turning off once. Embodiment J FIG. 1 is a control circuit diagram showing one embodiment of the present invention, and FIG. 2 is a state diagram showing the control state of illuminance 1 human body detection and lighting according to the present invention. As shown in FIG. 1, the cadmium optical sensor converts the illuminance of the lighting control area by the lighting fixture 10 into a voltage, and compares this voltage with a reference level in the level judgment circuit 12. When the level is below the reference level, the lighting is turned off. It determines that the required low illuminance state is present and outputs a low illuminance detection signal A of H level.The human body sensor 13 consists of 11, for example, a far infrared sensor,
As shown in FIG. 1, infrared rays from the lighting control area of the lighting fixture 10 are converted into voltage, this voltage is amplified in the amplifier circuit 14, and further compared with a reference level in the level judgment circuit 15 to determine the reference level. When it crosses the area, it is determined that a person has entered the lighting control area, and an H level human body detection signal B is output. The first timer circuit 16, on the condition that both the low-light detection signal A and the human body detection signal B are received at the same time, operates from the start of reception until the delay time TI elapses after the reception disappears. During this period, a high-intensity lighting signal C is output. The @2 timer circuit 17 continuously outputs the low-intensity lighting signal from the time when the certain delay time Tl indicated by the high-intensity lighting signal C has elapsed until the certain delay time T2 has elapsed. . The control circuit 18 controls the lighting of the lighting fixture 10 in the following four modes (a) to (d). (a) The low illuminance detection signal A output by the level determination circuit 12 of the illuminance sensor 11 is transferred via the OR circuit 19, so that the illuminance sensor 11 outputs the low illuminance detection signal A, and the human body sensor 13 It is determined that the human body detection signal B is not output, and the lighting equipment 10 is turned on at a low intensity (see FIG. 2). (b) The high-intensity lighting signal C of the first timer circuit 16 is transferred, and it is determined that the illuminance sensor 11 has outputted the low-illuminance detection signal A and the human body sensor 13 has outputted the human body detection signal B. , the lighting fixture 10 is turned on at high intensity. This high brightness lighting condition. This continues for two aforementioned delay times TI after the person leaves the lighting control area (see FIG. 2). (c) When no signal is transferred from an external circuit such as the first timer circuit 16, the illuminance sensor 11 does not output the low illuminance detection signal A, or the low illuminance sensor 11 does not output the low illuminance detection signal A, Then, it is determined that the human body sensor 13 does not output the human body detection signal B, and the lighting equipment 10 is turned off (see FIG. 2). (d) The low brightness lighting signal of the second timer circuit 17 is transferred via the OR circuit 19, thereby causing the illuminance sensor 11
Regardless of the output state of the lighting device 10, the lighting device 10 is turned on at a low brightness for a certain period of time T2 immediately after the lighting device 10 finishes high brightness lighting (see FIG. 2). Next, the operation of the above embodiment will be explained. According to the above embodiment, (a) when the illuminance of the lighting control area is low, such as in a guest room, and there is no person in the lighting control area, the lighting fixture 10 automatically turns on at a low level; (b) When the illuminance of the lighting control area is low, such as at night, and there is a person in the lighting control area, the lighting equipment 10 automatically turns on at high brightness; (c) During the daytime, etc. When the illuminance of the lighting control area becomes high and there is no person present in the lighting control area, the lighting fixture 10 automatically turns off. Furthermore, according to the embodiments described above, (d) when switching from mode (b) to mode (a), that is, under low illumination conditions such as at night, when a person leaves the lighting control area and the lighting equipment The lighting fixture 10 is forcibly turned on at a low brightness for a certain period of time T2 immediately after the high brightness lighting in mode (b) ends. Note that after a certain period of time in this mode (d), the illuminance sensor 11
outputs low illuminance and one human body sensor 13 outputs the absence of a person, so the lighting fixture 10 maintains low brightness lighting based on mode (a). That is, according to the above-described embodiment, when switching from the mode (b) to the mode (a), the lighting fixture 10 is in a relatively high-intensity remaining lighting state in which the lighting fixture 10 is switched from a high-intensity lighting state to a low-intensity lighting state. However, the control circuit 18 completely ignores the detection result by the illuminance sensor 11 during this remaining lighting period,
This creates a forced low-brightness lighting state for a certain period of time. Therefore, when automatically responding to changes in illuminance in the lighting control area and people entering and exiting the lighting control area, and always providing an appropriate lighting condition to the lighting control area, it is necessary to When exiting the lighting control area, the lighting fixture l
It is possible to reliably shift to low-intensity lighting without turning off the O light once. 2. The present invention can be widely applied to indoor and outdoor lighting. [Effects of the Invention] As described above, according to the present invention, when automatically responding to changes in the illuminance of the illumination area and people entering and exiting the illumination area, and always providing an appropriate illumination state to the illumination control area, When a person leaves the lighting control area under low illumination conditions such as at night,
To reliably shift lighting equipment to low-intensity lighting without turning it off once.
