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, the level adjustment circuit 2 in the circuit is used to adjust the level, so that the circuit can be used in indoor and square environments, and parameters suitable for the square environment can be added to the power supply part of the light source.

[0037] This system contains the control system for LED light sources in different building places. It only needs man-machine exchange control panel, liquid crystal display, input the relevant required illuminance value according to the illuminance requirements of different countries, after the password is locked and matches the LED light source of d...

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...
