The patent No. CN212673093U "A Gravity-Based Sensing Lamp" is based on the structural design of the gravity sensing element. When someone passes by, the lamp can be automatically turned on and off, which solves the problem of often forgetting to turn off the light or inconvenient turning on and off the light by hand.

However, in the previous cases disclosed above, none of them had the ability to consider personnel leaving temporarily and returning to the premises in a short period of time.

Today, the creator of this creation has developed this creation in view of the shortcomings in the actual implementation and use of the above-mentioned previous proposals.

The main purpose of this creation is to provide an area lighting control system. When it is determined that all personnel leave the lighting area space, the light source is first controlled to dim the lighting brightness and delay for a period of time. When a person enters the lighting area space again, the light source is controlled to restore the original lighting brightness. If no person enters the lighting area space within the delay time, the light source is controlled to be completely off and not emit light.

The lighting control system of this creative area is realized by the following technologies:

An area lighting control system mainly includes:

A regional lighting space with at least one entrance and exit;

At least one outdoor sensor installed outside the area lighting space and located at the corresponding and adjacent to the entrance and exit, the outdoor sensor will send an outdoor signal to the counter when it senses a person passing by;

At least one indoor sensor installed in the area lighting space and located at the corresponding and adjacent to the entrance and exit, the indoor sensor will send an indoor signal to the counter when it senses a person passing by;

A counter that receives the outdoor signal and the indoor signal, and performs addition or subtraction according to the order in which the outdoor signal and the indoor signal are received, that is, when the order of reception is the outdoor signal and the indoor signal When the counter counts up by 1, when the order of reception is the indoor signal and the outdoor signal, the counter counts down by 1, and the result value of the count is sent to the controller;

A controller includes a power adjustment unit and a delay unit. The controller determines whether there is a person in the area lighting space according to the received count value of the counter to control the power adjustment unit and the delay unit And the working state of the light source. When the count value is a positive integer greater than zero, it means that there are people in the area lighting space. The controller controls the light source to light up. When it is equal to zero, it means that there are no people in the area lighting space temporarily, and the controller informs the power adjustment unit to temporarily dim the brightness of the light source lighting. After a delay time, if the count value is still equal to zero , The controller controls the light source to be completely off and not to emit light;

At least one light source is electrically connected to the controller, and the controller controls the lighting state.

Advantages of this creation:

Compared with the existing technology, the area lighting control system of this case can ensure that when personnel leave the lighting area space for a short time and then return to the lighting area space, the lighting area space still retains weak light, which is conducive to the identification of the surrounding area. Environment to avoid collision and injury.

In order to have a more complete and clear disclosure of the technical content, the new purpose and the effect achieved in this creation, I will explain it in detail below, and please refer to the disclosed diagram and drawing number together:

First, please refer to the first and second pictures.

The lighting control system of this creative area mainly includes:

A regional lighting space 1 with at least one entrance 11;

At least one outdoor sensor 2 is installed outside the area lighting space 1 and located at the corresponding and adjacent to the entrance 11, the outdoor sensor 2 sends an outdoor signal to the counter 4 when it senses a person passing by ；

At least one indoor sensor 3 is installed in the regional lighting space 1 and located at the corresponding and adjacent to the entrance 11, the indoor sensor 2 sends an indoor signal to the counter 4 when it senses a person passing by ；

A counter 4 is electrically connected to the outdoor sensor 2, the indoor sensor 3, and is used to receive the outdoor signal and the indoor signal generated by the outdoor sensor 2 and the indoor sensor 3 respectively, and according to the reception The order of the outdoor signal and the indoor signal is counted up or down, that is, when the order of reception is the outdoor signal and the indoor signal, the counter counts up by 1, and when the order of reception is the For indoor signals and outdoor signals, the counter counts down by 1, and the result value of the count is sent to the controller 5;

A controller 5 is electrically connected to the counter 4. The controller 5 includes a power adjustment unit 51 and a delay unit 52. The controller 5 determines the area according to the received count value of the counter 4 Is there a person in the lighting space 1 to control the working status of the power adjustment unit 51, the delay unit 52, and the light source 6, when the count value is a positive integer greater than zero, it means the area lighting space If there is a person in 1, the controller 5 controls the light source 6 to light up. When the count value is equal to zero, it means that there is no person in the area lighting space 1 temporarily, and the controller 5 informs the power adjustment The unit 51 temporarily dims the illumination brightness of the light source 6 and after the delay unit 52 delays for a delay time, if the count value is still equal to zero, the controller 5 controls the light source 6 to be completely off No light

At least one light source 6 is electrically connected to the controller 5, and the light source 6 is controlled to emit light or extinguish through the controller 5.

Please refer to the second figure. When a person wants to enter the room from the outside (that is, inside the area lighting space 1), their walking path will go from the outdoors through the entrance 11 and then into the area lighting space 1, so the outdoor sensor 2 will first sense that a person passes by Obtain an outdoor signal, and then the indoor sensor 3 senses that someone has obtained an indoor signal. The outdoor signal and indoor signal obtained successively are sent to the counter 4 in sequence, and the counter 4 adds up and counts according to the sequence of the outdoor signal and the indoor signal. The count value is "1", and the count value of "1" is sent to the controller 5. The controller 5 judges that there is 1 person in the area lighting space 1 according to the count value of "1". Then the controller 5 drives the light source 6 to light up the lighting area lighting space 1. That is, as long as a person enters the room from outside, the counter 4 will count and increase by 1. As long as the count value of the counter 4 is not zero, the controller 5 will always light the light source 6 to illuminate the area lighting space 1.

When a person leaves the area lighting space 1 and walks outdoors, the walking path will go from the area lighting space 1 through the entrance 11 and then to the outdoors. Therefore, the indoor sensor 3 will first sense that someone passes through to get an indoor signal , And then the outdoor sensor 2 senses that someone obtains an outdoor signal. The indoor signal and outdoor signal obtained successively are sent to the counter 4 in sequence. The counter 4 counts down according to the order of the indoor signal and the outdoor signal, as shown in the third figure. There are 3 people in the original room. After one of them leaves, the counter 4 gets the count value of "2" (the original count value is 3), and sends the count value of "2" to the controller 5. , The controller 5 judges that there are still 2 people in the area lighting space 1 according to the count value of "2", so the controller 5 still drives the light source 6 to light up the lighting area lighting space 1.

Please refer to the fourth picture. The area lighting space 1 originally had 2 people. After one of them left, another person was about to enter the area lighting space 1. Therefore, there are still 2 people in the area lighting space 1. In the state, the final count value of the counter 4 is still "2", and the controller 5 still drives the light source 6 to light up the lighting area lighting space 1.

Please refer to the fifth figure. When the last person in the area lighting space 1 leaves, the count value of the counter 4 will be set to "0", and the counter 4 will transmit the count value of "0" to the controller 5, and the controller 5 will follow The count value of "0" judges that there are no people in the area lighting space 1. At this time, the controller 5 will notify the power adjustment unit 51 to temporarily dim the lighting brightness of the light source 6, and the delay unit 52 delays for a delay time. , If the count value returned by the counter 4 still maintains the state of "0", the controller 5 controls the light source 6 to be completely off and not emit light; if the light source 6 is weakened and light-emitted during the delay time, someone just enters or When the person who originally left returns and enters the area lighting space 1, the counter 4 obtains the outdoor signal and the indoor signal in sequence and counts it to obtain a count value of "1", and sends it to the controller 5, which is based on this The count value of "1" determines that there is a person in the regional lighting space 1, and controls the light source 6 to emit light to illuminate the regional lighting space 1 again.
