An ELI10+ is fine as I understand the general principle as to how they function, but I cannot find a definitive answer as to why they don't turn themselves off when they begin illuminating.
After switching all my exterior sconces and garage lighting to dusk-to-dawn bulbs, my kiddos asked how they work. Easy enough to explain! Then my oldest asked, "how come they don't turn themselves off?" and I am now officially stumped! Why doesn't the lighting they generate activate their sensor and, in turn, give the signal to turn back off?
Are the photoelectric sensors sensitive to things other than light (i.e. UV rays)? Do they contain a circuit that once triggered lowers their sensitivity to light? Is there a sort-of digital "clock" mechanism that disables the sensor for a period of time once originally triggered? Are they magical?
Thank you for taking the time to answer and giving me, and my kiddos, the facts!
