Principle of LED intelligent control technology
System through the front-end ambient light sensor detection, which can realize the scene illumination brightness adjustment, in addition, through the sensor to detect the ambient light color, to adjust the color of the lighting system, real-time adapt lighting equipment to the scene atmosphere. (LED chandeliers)
Communication function relies on all kinds of sensors, field control equipment and mainframe interconnection into a network to achieve remote control. (LED chandeliers)
In addition, if reconnected to the self-inspection module of the system and the power measurement equipment, it can not only accurately calculate the power consumed, but also provide the whole system with advance maintenance. (LED chandeliers)
These features, such as detecting ambient light color, communication, self-inspection and power measurement, will further save energy and reduce operating costs. (LED chandeliers)
Ambient light sensors are installed in all corners of the site to sample the amount of light on the site and feed it back to the host. These sensors are considered as outposts and eyes of the LED lighting system. (LED chandeliers)
When sensors collected already has plenty of room light, by its feedback the information to the host, the control program will spot lights dimmed or even completely shut down, not only save energy and prolong the life span of the lamp. (LED chandeliers)
This kind of front-end sensor mainly detects the luminance and power consumption of the lamp as well as the filtering of infrared and ultraviolet light in ordinary sunlight. (LED chandeliers)
Of course, these sensors should be efficient calmly running on the system, the work can't consume too much power, usually the quality of the ambient light sensor current shall not exceed 1 microamps, and lumen testing scope must achieve 0.1 lumens to the range of 100000 lumens, which is typical of outdoor environment illumination range, can meet the requirements of most applications. (LED chandeliers)
Considering the reliability and foresight of the system, it is necessary to install the front-end optical sensor with a larger detection range.
Filtering ultraviolet and infrared light that cannot be seen by the naked eye can effectively improve the accuracy of feedback data of environmental light sensors. (LED chandeliers)
LED intelligent control technology function
(1) intelligent LED light detection function
The installation position of the ambient light sensor should avoid the light irradiation of the lamp itself as far as possible, so that the environmental light measurement is not affected by other factors.
Design line, an ambient light sensor can be located in the independent circuit boards, avoid light irradiation in the shadows, this design makes the sensor in the accurate scope of the ambient light is detected more than the preset value, can sample data optical feedback in a timely manner to the host, which closed lighting control system.
If the designer adds three color sensors to the system, it will add more color and vitality to the field lighting.
(2) LED intelligent communication
When designing, make the lamp build into a network, control the switch of the lamp remotely through the network, adjust the light or adjust the color, greatly facilitate the control and reduce the human cost. (LED chandeliers)
Communication function makes it possible to maintain the system, especially to accurately determine the fault location and reduce the recovery time. (LED chandeliers)
Create GL7000 series dimming equipment by the way, for example, the brand good regulation performance, the quality components, users reflected in the use process for 9 years experienced only one the problems due to the damage of power transformer parts, more is artificial reasons such as equipment operators accidentally touch broken line, lead to poor communication problems, due to its own communications self-diagnosis function, when a communication failures, can detect the position of the breakpoint, immediately after to facilitate the engineering staff of the rapid repair.
(3) intelligent LED lighting power measurement function
Along with the expansion of intelligent to various fields, intelligent LED lighting system should also have the function of the power consumption statistics, or computing, the current power supply departments have been cancelled human on-site meter reading, instead, the intelligent remote meter reading, almost all the smart grid terminal equipment has the function of electric energy measurement, able to provide more accurate power department and user and the power of the real-time data information, makes the power supply department can clear to collect fees, the user can clearly.
