Consult the LED plant growth lamp, intermittent intermittent illumination, with a light dark period of 1:2 and an amplitude of 200us:400us",
LED plant growth lights, intermittent intermittent irradiation, light and dark cycles of 1:2, and the range of 200us:400us means:The LED light, which is used as a lighting for plant growth, is not long bright, but bright dark alternating. The duration of light is 200 microseconds, and the extinction time is 400 milliseconds, that is, the dark time is two times the brightness time
It seems interesting that the "LED growth lamp" has a high demand for power, and requires a dedicated switching constant current drive with specialized clock signals
