The Use of
Phosphorous in Light Bulbs
By John
Mack Freeman
Phosphorus,
from the Greek meaning "light-bringer," is an element commonly used
in light bulbs.
However,
it should not be confused with "phosphors," which is instead any
substance that exhibits luminescence.
Phosphorus,
though, is a phosphor and does exhibit this luminescence.
Fluorescent Light
Sometimes,
the phosphor coating on the inside of fluorescent lights includes phosphorus in
the metallic salt lining the inside of the light bulb.
These
coatings produce light by having particles of radiation hit the coating from
the inside of the tube, causing them to fluoresce.
LED Technology
Blue
phosphorus is the most commonly used type of light-emitting diode (LED). To
produce white light (as an alternative to fluorescent light), blue phosphorus
LEDs are used with energized yellow phosphorus.
Danger
There is
a lot of speculation that phosphorus is dangerous because it can cause adverse
reactions such as kidney damage and osteoporosis if encountered too often.
The
phosphorus commonly used in these materials either reacts with oxygen quickly
or is otherwise rendered inert, making them effectively harmless to humans.
