| Nowadays, visiting the exhibition has become the modern lifestyle, more types of museums, temporary exhibitions had been increased, and due to the rapid pace of construction,a lot of the exhibits on display at the destructive exhibition light environment.The light does not show the exhibits’ real art,Thant light pollution make a negative psychological impact on visitors.That lead to a double loss not only on material but also on spiritual.For this problem,I designed an intelligent lighting system based on constant illumination dimming driver with LED. For the wireless signal transmission,I selected Zig Bee which has low power consumption and strong networking capabilities.The soft platform is TI’s Zig Bee Home Automation1.2.2Profile platform.The products certificated with the ZigBee3. 0 specification,which means it can be used in commercial production.This paper completed the following works:1.Based on Led light characteristics, designed a high efficiency, high reliability AC\DC drive power.2.Selected the LED dimming technology,designed the dimming Circuit;3.Selected the cc2530 MUC chip, complete system hardware structures. Given system problems and the solutions.4. Building the system software platform and the dimming PID algorithm,and the use Z-stack to complete the Intelligent Light System software development;5. Did reliability test, to verify the feasibility of the system design. |
