By adjusting the driving power of the chicken coop special lamp, the dimming effect of the chicken coop special lamp can be realized. Since the brightness of the chip and the driving current have a fixed ratio.
Dimming is often referred to as mimicking dimming mode or linear dimming. This kind of chicken coop special lamp dimming, when the driving current increases or decreases linearly, it will relatively reduce the chip of the chicken coop special lamp, and the immunity of the control circuit is strong on the overshoot effect of the driving current.
The third method of dimming is the pulse light regulator, which is to control the square driving current, variable pulse width, and then change the duration after adjusting the pulse width, and can also achieve energy-saving effects at the same time as output. Under normal circumstances, the frequency conversion speed regulation of the chicken coop special lamp can be maintained at 200Hz ---1000Hz, which is retained by human vision, and then people cannot feel the flickering of light and the process of movement. It can improve the heat dissipation effect of chicken coop special lamps.
In summary, the adjustment method of the chicken coop special lamp is based on the specific classification of the drive current output control of the chicken coop special lamp, and the control circuit can also be divided into analog control and PWM control, and the control circuit is completed by control.
At present, in the field of road lighting, the scope of use of chicken coop special lamps is spreading rapidly, long service life and reliable performance is still a matter of consideration, but with the continuous development and progress of technology, when the problem of service life and reliability is properly solved, to a certain extent, the lighting application procedure of chicken coop special lamps will inevitably move towards the pace of intelligent adjustment system.
