As we known, LED
(light emitting diodes) lights have so many advantages compared to other
lights. For example, use less power, are more durable, give off less
heat and last 25 times longer than a standard incandescent light bulb.
Common LEDs are made up for four simple parts that maximize the
efficiency by minimizing the heat generated and therefore energy wasted
by the bulb.
LED Chip
The LED chip is a light emitting semi-conductor and the central piece
of an LED light. The chip sits in the center of the bulb, surrounded by
the other three pieces, and is the portion of the bulb that actually
lights up.
Gold Wire
The gold wire’s function is to connect the metal pin at the top of
the chip to the lead frame. The wire allows the electricity from the
frame to carry into the chip which makes it light up.
Lead Frame
And what is the function of the lead frame in the LED? It is used to
hold the chip in place, and connected to it by the gold wire. The frame
extends through the bottom of the bulb and provides the actual connection to the electrical source.
Plastic Package
A plastic package is placed around the bulb, much like the glass of
an incandescent bulb, to hold the rest of it place and protect and bulb
and the user. But the most visible part of the bulb is also the part
that serves the least in the actual function. The color of the plastic
does not dictate the color of the light.
So now you have learned more about LED lights and it will be easier to maintain yours.
