Problems solved by technology

[0002]With the rapid development of LED lighting technology, LED has been widely used in indoor lighting, but in the actual use process, most of them still use traditional human control methods at present, with Realize the lighting and extinguishing of LEDs. When there are multiple LED light sources installed indoors, because different LED light sources have mutually independent brightness values, users cannot realize the control of illuminance adjustment according to actual lighting needs when using them, and often need to turn on all of them. On the one hand, it is easy to increase the energy consumption of the entire lighting system, and on the other hand, it also makes the illuminance of the same plane fluctuate greatly, which affects the user's visual experience

Embodiment 1

[0109] The indoor lighting scene of this embodiment is as follows image 3 As shown, the room is set to be 5m long, 5m wide, and 3m high, and 16 LED arrays are distributed on the ceiling with an array spacing of 1.25m. Each LED array contains 49 LED light sources, and the LED light source spacing is 4cm. The sampling area is even Distributed on the user receiving plane at a height of 0.85m from the ground, the spacing between sampling areas is 0.2m, the power of each LED light source is 0.452W, and the half angle of the transmission power is 80°.

[0110] Figure 4a ~ Figure 4d It is a schematic diagram of the effect of the lighting scene without energy-saving control and after energy-saving control. The comparison of the illuminance data of the sampling area before and after the control is shown in Table 1:

Embodiment 2

[0120] In order to further verify the uniform distribution effect of illuminance of the energy-saving control method of the present invention, this embodiment builds a physical demonstration model, which is composed of 36 LED lamp groups, LED brightness controllers and transformers, as shown in Figure 7a Shown: Each light group has 3 LED lights, 36 light groups are independently controlled by the controller, and the LED brightness controller uses a stable and reliable 51 single-chip microcomputer as the hardware control core. The optimized light source brightness is obtained through MATLAB simulation calculation, and then the data is written into the SD card, and the controller reads the SD card data, controls different LED light groups according to different values, and outputs different brightness scenes.

[0121] Comparing the illuminance of the same receiving plane before and after energy-saving control, the uncontrolled lighting scene is as follows Figure 7b with Figu...

Abstract

The invention relates to an LED energy-saving control system and a method thereof. The method comprises the steps that a user terminal transmits received user lighting demand information to a controlcomputer; the control computer constructs an energy-saving linear programming model to solve and obtain a corresponding LED lamp set control instruction; the LED brightness control module controls each LED lamp source to carry out lighting output according to the LED lamp set control instruction; the user terminal collects the current LED lamp set receiving illuminance at a preset time interval, the collected LED lamp set receiving illuminance is compared with the user lighting demand, if the difference value between the two exceeds a preset threshold value, correction demand information is outputted to a control computer, and the control computer solves and obtains a corresponding LED lamp set control instruction by constructing a correction linear programming model; or otherwise, the current step is continuously executed. Compared with the prior art, the LED lamp source is controlled to emit light on the basis of the linear programming optimization algorithm, so that a user can obtain the required lighting effect at different positions, and the energy consumption can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of indoor LED control, in particular to an LED energy-saving control system and method thereof. Background technique [0002] With the rapid development of LED lighting technology, LED has been widely used in indoor lighting, but in the actual use process, most of them still use traditional human control methods to realize the lighting and extinguishing of LEDs. When multiple LEDs are installed indoors As for the light source, since different LED light sources have mutually independent brightness values, the user cannot realize the illuminance adjustment control according to the actual lighting demand during use, and often needs to turn on all the LED light sources. On the one hand, it is easy to increase the energy consumption of the entire lighting system , on the other hand, it also makes the illuminance of the same plane fluctuate greatly, which affects the user's visual experience.
