Embodiment 1

[0029] This centralized constant current LED intelligent illuminance control lighting system is used in the implementation plan of classrooms. When it is applied, this circuit system will be made into a control terminal, and the components of this intelligent system will be integrated on the PCB, and then used in a moisture-proof shell. When packing and installing, install the illuminance sensor. This solution uses the first high-precision phototransistor DCS; arrange the illuminance sensor everywhere on the roof, install the control terminal in a ventilated and moisture-proof place, and set the operating touch screen on an easy-to-operate Next to the blackboard, or other places that are easy to operate in the classroom, before using it, it is necessary to calibrate the threshold value inside the controller. Generally, during the calibration, test light sources are arranged at the four corners of the desk, blackboard, lecture table and classroom. Adjust the light source to 400l...

Embodiment 2

[0036] This centralized constant current LED intelligent illuminance control lighting system is used in the implementation plan of indoor and outdoor squares. The control terminal used can completely transplant the control terminal in Example 1, but the layout of the illuminance sensor is changed, and it is generally arranged near the square. In buildings without shelter, when in use, adjust the level through the level adjustment circuit 2 in the circuit to make the circuit suitable for use in indoor and square environments, and add parameters suitable for the square environment to the power supply part of the light source.

[0037] This system contains control systems for LED light sources in different building sites. It only needs man-machine exchange control panels, liquid crystal displays, and input of relevant required illuminance values ​​according to different national illuminance requirements. There is no need for personnel control, and it will work intelligently and au...

The man-machine interface exchange unit includes a control panel, an LCD, a work parameter setting circuit, a password setting and locking circuit etc. The LED light source is composed of an LED radiator and a patch LED matrix unit. Therefore, a set of intelligent illumination lighting control system for the illumination environment with different requirements can be realized.

Description

technical field [0001] The invention relates to the field of lighting control, in particular to a centralized constant current LED intelligent illuminance control lighting system. Background technique [0002] Illumination is an environmental condition that people cannot live without, such as the learning environment. Now the national lighting standard for primary and secondary school teachers GB7793-87 sets that the minimum value of the lighting coefficient on the classroom desk should not be lower than 1.5%. But in reality, the lighting of classrooms is generally poor, especially in the north of the classroom, and some of the classrooms; the lighting is insufficient in places far away from the window. Now, in order to save energy, most classrooms use LEDs as light sources. LEDs are called the fourth The modern light source has the characteristics of energy saving, environmental protection, safety, long life, low power consumption, low heat, high brightness, waterproof, min...
