 2.3 of photoperiod on growth of aquatic organisms

  MR16 

Natural sun light period of about 10 : 00 ~ 15: 00 , the irradiation time of about 5 ~ 6h, consider the light intensity of artificial light as strong sunlight , it is recommended aquarium light source 6 to 8 hours of lighting is appropriate,

 and in segmented lighting the way : " 10 percent the amount of light × 1h-80% light intensity × 6h-20% the amount of light × 1h" better, ie the amount of light to "weak → in → strong → in → weak" illumination period , with the power supply timing control lights, lights-out time , so that the light can meet the growth of aquatic organisms photoperiod .

3 Aquarium Lighting LED light design portfolio

Microcomputer Control LED Aquarium lighting device mainly includes two aspects of the design : the hardware and software design . Hardware design includes LED combination lamps , LED drivers and circuit control system has three major ( block diagram shown in Figure 2). LED combination lamps lamp module from the main composition and ornamental modules , LED constant current drive mode buck circuit the control system used to implement the light color, light intensity and exposure time , automatic regulation of the length of the segment . Software  LED Flexi design is modular program design ideas, combined with flexible spectrum regulation based methods using C language, and the organic integration with the hardware , and GSM networks via keyboard control master twofold approach to achieve the desired aquatic animals and plants to provide full emulation spectrum function.
