What is the layer of an LED bulb that stores energy?
Your LED bulb can store energy either in the Phosphor Layer or in the LED driver of the bulbs. The Phosphor Layer, or otherwise called “Phosphor Coating” is a layer that is common to blue LEDs that allows it to display the white color. The coating absorbs the blue wavelength allowing the light to pass through and display white.
What is the phosphor layer of an LED bulb?
While this layer is helpful in absorbing the blue wavelength, it is still a phosphor layer. Phosphor layers, by their very nature, are materials that absorb energy. Similar to your glow in the dark stickers that glow when it absorbs enough energy, albeit weakly, the phosphor layer of your LED bulb will glow if it collects, and absorbs enough energy.
Why does afterglow not add to my electric bill?
The afterglow also does not add to your electrical bills because the energy is not derived from the power being switched on. It just so happens that the bulbs managed to store energy. The afterglow also does not make you susceptible to fires because the problem is not with the wiring.
