are transforming lights?
By Jerri Simmons
When you think about the light industry you
might think about incandescent or fluorescent
lights. But, a new light is transforming this
industry.
Sir’tauria Hilliard said she thinks about
lights most when she changes a bulb.
“You turn the switch off, so
you won’t burn your hands, and then you
unscrew it and then you get a new one and you
screw a new one,” she said.
The process she describes is something Americans
have done for years with incandescent and fluorescent
light bulbs. But if you look at this cell phone
or traffic light you’ll notice LEDs or
Light emitting Diodes.
LEDs aren’t just used for big technologies
outside of the home. In fact, LED lights have
been in the home in the form of electronics.
LEDs form the numbers in digital clocks
and are located at the tip of most remote controls.
There are several advantages to LED lights
Advantages of LEDs:
-Power efficient
-Has a long life span.
-Fails by dimming over time.
-Gives off less heat.
-Lights up quickly.
If you’re thinking of replacing your current
bulbs with LEDs, you may want to think again.
LEDs can replace incandescent and flourescent
light bulbs in the house, but that requires
a power source conversion in household applications,
and this can be expensive.
Lois Lewis says she would be willing to try
LED lights if the costs decrease.
“Well, I like to try different things,
I would try them to see how they worked, and
if they didn’t work as well as I thought
they should or do what I thought it ought to
do then I would go back to my old ones,” said
Lewis.
Proponents of LEDs expect that technological
advances will reduce costs so that these lights
can be introduced into most homes by 2020. But
for now you can find most LEDs used in electronics
and used as indicator signals.
