[0028] The present application is further described in detail below in conjunction with the accompanying drawings.

[0029] An energy-saving control system for a lighting lamp comprises a lighting unit, a power supply device, a detection device and a control device. The lighting unit comprises a plurality of lighting lamps. The power supply device is connected to the lighting lamps and is used to supply power to the lighting lamps. The detection device comprises at least one camera, which is arranged at at least one lighting lamp and is used to sense the brightness of the lighting lamp and the ambient light respectively according to the waveform frequency. The control device is electrically connected to the camera and the power supply device respectively, and is configured to adjust the brightness of the lighting lamp through the power supply device according to the light intensity signal collected by the camera.

[0030] According to the energy-saving control system of the lighting lamp of the present application, the brightness of the lighting lamp can be continuously adjusted according to the brightness of the ambient light, which can not only achieve a better lighting effect, but also avoid high-brightness lighting when the ambient light is good, thereby avoiding energy waste and saving energy.

[0031] Optionally, the lighting unit can be used to lay out lighting lamps in an area, such as a main road in a municipal lighting system, or a partial area of ​​an indoor lighting system.

[0032] Optionally, the power supply system may include a power supply and a power regulator, the power supply is electrically connected to the power regulator, and the power regulator is electrically connected to each illuminating lamp. The control device is electrically connected to the power regulator, so that the brightness of the illuminating lamp can be adjusted by the power regulator.

[0033] Optionally, the control device controls the on and off of the lighting lamp according to the waveform frequency, and can control the lighting lamp to have lighting gaps, so that the brightness of the ambient light can be sensed, and the brightness of the lighting lamp can be adjusted.

[0034] Optionally, the waveform frequency has a passage band and a disconnection band that are set at intervals along time. The control device controls the passage between the power supply device and the lighting lamp in the passage band, and controls the disconnection between the power supply device and the lighting lamp in the disconnection band, thereby realizing the brightness sensing of the ambient light. Preferably, the duration ratio of the passage band and the disconnection band is at least 10:1, thereby reducing the extinguishing time of the lighting lamp and minimizing the brightness of the sensed ambient light that affects the use of the lighting lamp. More preferably, the disconnection band of the lighting lamp can be controlled to be 0.05 to 0.1 seconds, so that it is difficult to be perceived by the human body.

[0035] Optionally, the control device calculates the brightness of the lighting lamp and the ambient light according to the image information collected by the camera, including:

[0036] Extract the brightness of each pixel in the image information;

[0037] The brightness of each pixel is compared with the preset brightness threshold to calculate the average brightness in the image information.

[0038] Through the above settings, the brightness of the image information collected by the camera can be sensed, and then the brightness of the ambient light and the light when the lighting lamp is turned on can be sensed.

[0039] The camera can be arranged on the lighting lamp, and can also be arranged near the location of the lighting lamp.

[0040] Furthermore, the brightness of each pixel is compared with a preset brightness threshold, so as to calculate the average brightness in the image information, including:

[0041]

[0042] Among them, L represents the average brightness of the image information, I ij is the pixel value of the image information at position (i, j), W and H are the width and height of the image information respectively, w ij The brightness of the pixel at position (i, j) is obtained by comparing it with the preset brightness threshold.

[0043] Through the above calculation method, the average brightness of the collected image information can be calculated, so as to sense the brightness of the ambient light and the light when the lighting lamp is turned on.

[0044] Furthermore, the brightness of the pixel is compared with a preset brightness threshold to obtain the brightness, including:

[0045] Collecting reference images of different brightness through a camera (consistent with the camera required for sensing), thereby comparing and obtaining the chromaticity range corresponding to the reference pixel points of the collected reference image in different brightness ranges;

[0046] The chromaticity of the pixel is compared with the chromaticity corresponding to each reference pixel, and the brightness of the pixel that falls within the chromaticity range of the corresponding reference pixel falls within the brightness range of the reference pixel.

[0047] Through the above settings, the image information and brightness collected by the camera can be associated in advance through the camera and the relevant photosensors, and then the chromaticity of the pixel point is compared with the chromaticity corresponding to each reference pixel point, and the brightness of the ambient light or light when the image information is collected by the camera can be obtained by comparison. The data is accurate, easy to calibrate, and easy to operate.

[0048] The camera captures the white reflector to collect image information, thereby unifying the environmental conditions when the camera collects image information, preventing the environmental image from interfering with brightness sensing, and making brightness sensing more accurate.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
