The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The flow of the embodiment of the luminaire control method is as shown in FIG. 1. The luminaire control method includes: Step 100: Acquire image data near the luminaire;

Step 101: Determine whether at least one person exists in the image data, and obtain a first judgment result;

Step 102. When the first determination result indicates that at least one person exists in the image data, perform a first control operation, so that a light emission brightness of the light fixture is higher than the first brightness, until the determining is performed according to the subsequently acquired image data. After there is no person in the image data, the second control operation is performed such that the illuminating brightness of the luminaire is lower than the second brightness, and the second brightness is less than or equal to the first brightness.

Through the above operation, at the midnight or some time or place where the light is used less, when the existing activity of the hair is detected by the camera, the brightness of the light of the lamp is adjusted to be higher than the brightness of the first brightness, and the brightness of the lamp can be adjusted according to actual conditions. Increased the practicality of the luminaire.

For example, there are 100 盏 100 watt lamps on a certain road for illumination. If the 100 lamps are illuminated with the highest brightness, then 10 kWh will be consumed in one hour, if the luminaire control method described in this embodiment is used. Set the luminaire to illuminate with 50% maximum brightness. When the activity is found, the brightness of the luminaire is increased from the highest brightness of 50%, while the pedestrian is passing the street light. The space is very short and can be neglected, so it will consume 5 kWh in one hour at this time, which greatly reduces the power consumption of the luminaire while ensuring the illumination of the user.

The luminaire provided in this embodiment can be used in various applications, can be used as lighting street lamps on both sides of the road, can also be used in the corridors and rooms of the office building, and used for lighting the staff working in the office building, Can be used in other places where lighting is required.

In the process of lighting the existing luminaires, at midnight or during periods of low light use, the luminaires are still illuminated with the highest brightness, which leads to waste of electrical energy and increases the cost of the luminaires.

In this implementation, the method further includes:

Obtaining time data of the area where the luminaire is located;

Specifically, the midnight time period is generally: 0:00 to 5:00, and can also be set according to the needs of the user.

Through the above operation, the brightness of the luminaire can be adjusted to a preset first brightness at midnight or some time periods when the use of less light, which can automatically reduce the brightness of the luminaire, save power, and avoid a large amount of power loss. The cost of using the luminaire is low.

At present, the lamps used for lighting are generally in the state of strongest brightness and remain bright after being turned on, and the consumption of electric energy is very large.

In this embodiment, when the second determination result indicates that the area where the luminaire is located is not in the midnight time period, the method further includes:

Obtaining a current ambient brightness near the luminaire;

Obtaining, in a correspondence table between the ambient brightness and the brightness value of the luminaire, a luminaire brightness target value corresponding to the current ambient brightness; Performing a fourth control operation, controlling the illuminating brightness of the luminaire to be the illuminance target value of the luminaire. Through the above operation, the brightness of the lamp is adjusted according to the brightness around the lamp, and the power consumed by the lamp is effectively saved.

The existing lamps in the same area are basically unified time switches. However, the set switch lights time is applicable to some areas, but for some areas, the day may still be bright but the set time for turning on is up. It must be turned on, but for other areas, it has been dark for a while, but it has not been turned on, so you can only turn on the lights when the time for turning on the lights is turned on. It is not possible to switch lights according to the actual situation of the area.

When the luminaire needs to be turned on or off, the method further includes:

Obtaining the latitude and longitude of the area where the lamp is located;

Through the above operations, the lights can be automatically turned on or off according to the actual situation. It is not necessary to turn on or off the lights according to the uniform time, so that the switches of the lamps are more precise, more in line with the actual application, and fully meet the daily needs.

The luminaire control method is further described by the following embodiments.

A brief flow of a further embodiment of the luminaire control method includes the following steps:

Step A. According to the set latitude and longitude schedule, when the sunset time of the day is reached, the ready to turn on the light command is issued;

Step B. According to the latest ambient brightness reported by the light sensor, set the switch brightness value, and issue the turn-on and brightness value commands at the same time;

Step C. According to the latest ambient brightness of the optical sensor, the system performs the brightness adjustment command according to the latest ambient brightness value. If the brightness adjustment threshold is not reached, the dimming command is not issued.

Step D. After reaching the late night time period (for example, 00: 00-5: 00), the brightness adjustment is performed according to the set late night brightness value, for example, the preset brightness value is 50%, and the light sensor is in the off state during this period. State

Step E. Turn on the camera in the middle of the night, and judge the activity of the person according to the dynamic activity value of the video returned by the camera. When someone is active, adjust the brightness according to the preset value; when the active value decreases, the brightness is restored. ;

Step F. When the dawn time is reached, the light sensor is turned back on, the brightness is adjusted according to the ambient brightness collected by the light sensor, and the camera is turned off;
