The existing intelligent lighting system can turn on and off the lighting according to the ambient illuminance and the movement of the human body. Chinese Invention Publication No. CN101527981A discloses an intelligent lighting system, which includes two sensing modules of light sensing and infrared motion sensing. The light sensing and infrared motion sensing modules are respectively used to detect the ambient illuminance and whether there is human body movement. When the ambient illumination is low and there is human activity, the lights in the intelligent lighting system are automatically turned on. Therefore, the intelligent lighting system solves the problem that users need to manually switch lamps and lanterns, and at the same time has the function of saving electricity, which can meet the needs of users for general indoor lighting.

However, in different time periods, people have different requirements for lighting brightness. For example, during the time of waking up at night, the light brightness of general general lighting will cause discomfort to people who wake up at night, and it will also affect the sleep of others.

Detailed ways

In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Please refer to FIG. 1. FIG. 1 is a schematic structural diagram of a preferred embodiment of a lighting system provided by the present invention. The lighting system includes: an illuminance sensing module 11, a human body sensing module 12, a clock module 13, and a general lighting module 14 , lighting module 15 at night, timing module 17 and control module 16. The illuminance sensing module 11 , the human body sensing module 12 , the clock module 13 , the general lighting module 14 , the night lighting module 15 and the timing module 17 are respectively connected with the control module 16 .

Each module in the lighting system of this embodiment will be described in detail below.

The illuminance sensing module 11 automatically detects the ambient illuminance, and transmits the obtained illuminance detection signal to the control module 16 . In an embodiment of the present invention, the illuminance sensing module 11 can automatically and real-time detect the ambient illuminance in a certain area (such as indoors), and transmit the obtained detection signal to the control module 16 in real time while detecting the indoor ambient illuminance . Specifically, the illuminance sensing module 16 includes at least one light sensor installed indoors, and the light sensor detects the ambient illuminance in the room.

The human body sensing module 12 automatically detects whether a person moves, and transmits the obtained human body detection signal to the control module 16 . It should be noted that the human body sensing module 12 is mainly used to detect whether the human body has a relatively large movement, such as the nighttime activity of the human body during the night time period. In the embodiment of the present application, the human body sensing module 12 can be a passive infrared detector, which can be installed in a suitable position indoors, and is used to detect whether a person moves in real time. The passive infrared detector includes an infrared sensor. The passive infrared detector detects changes in thermal radiation located in an indoor space. When there is no moving human target in the indoor space, the energy of infrared radiation of all background objects (such as walls, furniture, etc.) at room temperature is relatively small and basically stable. When a human body walks in the detection area, it will cause changes in the energy of infrared thermal radiation. The infrared sensor converts the change of the received infrared thermal radiation energy between the active human body and the background object into a corresponding electrical signal, and the processed electrical signal can be regarded as a human body detection signal. When the human body sensing module 12 detects that someone is moving, it transmits a human body detection signal to the control module 16 .

The clock module 13 provides real-time time for the lighting system, and transmits the obtained real-time time signal to the control module 16 .

The general lighting module 14 provides general lighting during the preset non-night time period. The general lighting module 14 is an LED lamp group. The general lighting module 14 provides high-brightness lighting to meet people's lighting needs during night work, leisure and other activities.

The night-time lighting module 15 provides night-time lighting during the preset night-time period. The night lighting module 15 is also an LED lamp group. The night-time lighting module 14 provides lighting with weaker brightness, which only needs to meet people's indicative lighting needs during the night-time period.

The general lighting module 14 and the night lighting module 15 can be integrated together as a lighting module.

It should be noted that the non-night time period and the night time period are preset by the lighting system, and of course, can also be customized according to the user's own work and rest habits and seasons of the lighting system. For example, if the set wake-up time period is from 22:30 in the evening to 6:30 in the morning of the next day, then the non-night wake-up time period is from 6:30 in the morning to 22:30 in the evening.

Timing module 17, when the night lighting module 15 of the lighting system provides night lighting, that is, when the night lighting is turned on, and after no human body moves, the timing module starts to record the opening time of the night lighting, and passes the time signal to control module 16.

The control module 16 can be controlled according to the real-time time signal provided by the clock module 13 to provide general lighting (turn on the general lighting) by the general lighting module 14, and provide the night lighting (turn on the lighting at night) by the lighting module 15 for getting up at night. ).

The control module 16 can judge whether to turn on the general lighting or the night lighting according to the illuminance detection signal transmitted from the illuminance sensing module 11 , that is, according to the brightness of the room.

The control module 16 can judge whether the person is moving according to the human body detection signal transmitted from the human body sensing module 12 . When the control module 16 receives the human body detection signal, it means that the person is moving, and if the control module 16 does not receive it, it means that the person is not moving.

The control module 16 can judge whether the recorded wake-up lighting duration exceeds the preset turn-on duration of the wake-up lighting according to the duration signal transmitted from the timing module 17, and determine whether the wake-up lighting is turned off according to the judgment result.

The control module 16 is an MCU control chip.

The control module 16 controls the lighting conditions of the general lighting module 14 and the night lighting module 15 according to the signals received from the illuminance sensing module 11 , the human body sensing module 12 and the clock module 13 . The lighting conditions include whether the general lighting module 14 provides high-brightness lighting, or the night-time lighting module 15 provides low-brightness lighting, and whether the general lighting module 14 and the night-time lighting module 15 are turned on or off.

The present invention also provides a control method for the above lighting system. Please refer to FIG. 2. FIG. 2 is a schematic flow chart of a preferred embodiment of the control method of the lighting system of the present invention, specifically illustrating the control method of the lighting system. The method includes the following steps:

S21: Determine whether the acquired illuminance detection signal is lower than a preset illuminance opening threshold.

It should be noted that the lighting system of the present invention presets an illumination opening threshold, and the illumination opening threshold refers to an illumination critical value. Of course, the illumination opening threshold can also be customized and modified according to the user's adaptability to the environmental illumination.

After the control module 16 receives the illuminance detection signal sent by the illuminance sensing module 11, it compares it with the preset illuminance opening threshold, and if the illuminance detection signal is lower than the preset illuminance opening threshold, then the control module 16 is satisfied with the general purpose of opening control. A condition of the lighting module 14 or the night lighting module 15 .

S22: Determine whether the human body moves.

When the control module 16 receives the human body detection signal sent by the human body sensing module 12, it can confirm that the human body has moved. If the control module does not receive the human body detection signal, it indicates that the human body has not moved.

S23: Determine whether the current time is the wake-up time.

The control module 16 can obtain a real-time time signal, and judge whether the current time is the wake-up time according to the obtained time signal.

When the illuminance detection signal is lower than the preset illuminance opening threshold, the human body moves, and the current time is the wake-up time, the night-time lighting is turned on.

When the illuminance detection signal is lower than the preset illuminance opening threshold, the human body moves, and the current time is not the night time, the general lighting is turned on.

When the illuminance detection signal is lower than the preset illuminance opening threshold and the human body does not move, the lighting system will not start the general lighting or night lighting.

When the illuminance detection signal is higher than the preset illuminance opening threshold, the lighting system will not start lighting.

Through the control method of the lighting system of the present invention, the lighting conditions under the above different conditions are obtained.

It should be noted that when the human body does not move, the control method of the lighting system further includes the following steps:

S24: When the human body does not move, start to record the time when the lighting is turned on at night.

S25: Determine whether the recorded turn-on duration of the wake-up and night lighting exceeds the preset turn-on duration of the wake-up and night lighting.

The lighting system presets the turn-on time of the night lighting, for example, the preset turn-on time of the night lighting is 10 minutes. The confirmation result can be obtained by comparing the turn-on time of the night light recorded by the timing module 17 in the lighting system with the actual turn-on time of the night light.

When the turn-on time of the wake-up lighting exceeds the preset turn-on time of the wake-up lighting, the illuminance detection signal is lower than the preset illuminance opening threshold, and when the current time is the wake-up time, the night lighting is turned off.

When it is confirmed that the obtained illuminance detection signal is not lower than the preset illuminance opening threshold, the following steps are required:

S26: Determine whether the acquired illuminance detection signal is higher than a preset illuminance shutdown threshold.

It should be noted that the lighting system also pre-sets an illuminance shut-off threshold. The illuminance shut-off threshold refers to an illuminance critical value. Thresholds are compared, and if the illuminance detection signal is higher than the preset illuminance shutdown threshold, the control module 16 will turn off the general lighting module 14, that is, turn off the general lighting.

S22: Determine whether the human body moves.

S23: Determine whether the current time is the wake-up time.

When it is confirmed that the acquired illuminance detection signal is lower than the preset illuminance opening threshold and the human body does not move, the general lighting is turned off.

When it is confirmed that the acquired illuminance detection signal is lower than the preset illuminance opening threshold, the human body is moving, and the current time is not the night time, continue to turn on the general lighting.
