Embodiment Construction

[0026] like figure 1 , The system of the present invention includes a wall switch, a power supply unit, a white LED light source, a dimming unit, a wired illuminance sensing unit, a wireless illuminance sensing unit and a remote control unit. Except for the wall switch, the wired illuminance sensing unit, the wireless illuminance sensing unit and the remote control unit, all the above units are located inside the lamp.

[0027] like figure 2 As shown, a room lighting system model, considering the contribution of sunlight to indoor lighting, the system includes: illuminance sensing unit, power supply unit, control unit, white LED light source, remote control unit and wall switch, power supply and signal of each unit of the system transfer relationship such as figure 1 As shown, the solid line represents the power supply relationship, and the dotted line represents the control signal.

[0028] The power supply unit converts the AC mains power into a constant current source a...

Abstract

The invention discloses an LED illumination control system which includes an LED light fixture and a large-power LED driving unit and also includes an illuminance sensing unit used for detecting an illumination area and a processing unit. The illuminance sensing unit includes a wired illuminance sensing unit and a wireless illuminance sensing unit. The processing unit is connected with the large-power LED driving unit and the wired illuminance sensing unit and is also connected with the wireless illuminance sensing unit through a radio-frequency transceiving unit. The processing unit receives detection data of the wired illuminance sensing unit and the wireless illuminance sensing unit and obtains an adjustment input quantity of the large-power LED driving unit through a PID control algorithm according to the difference value of the detection data and an illuminance threshold and sends an illuminance adjustment instruct so that adjustment of the illuminance of the LED light fixture is realized and the illuminance of a work face is kept stable. The illumination control system is capable of ensuring stability of the light intensity of an illumination area, particularly a work face. At the same time, the system is convenient to operate and has remote control and self-induction functions and the like.

Description

technical field [0001] The invention relates to the fields of automatic control, wireless communication and embedded technology, more specifically, an intelligent control system for home and office lighting. Background technique [0002] At present, switch-type lighting control methods are generally used in home lighting. When the indoor illuminance is lower than the critical value, which affects people's cognitive behavior, go to the switch and press the switch to turn on the light, or turn the knob to adjust the intensity of the light source. Most of the wireless lighting control systems that can turn on and off the lights by remote control that appeared later only have the function of manually adjusting the intensity of the light source. Neither of these two control methods introduces the illuminance feedback link, and is only based on the subjective perception of the human eye. Since the contribution of sunlight to indoor lighting is not considered, there is a lack of co...
