LED is standed
for Light Emitting Diode,a kind of semiconductor which is used to give
and receive the electronic signal into infrared rays or light, using
the characteristics of compound semiconductor. This is used for
household appliances, remote controller, electric bulletin board,
various kinds of automation appliances.
An LED is a solid-state electronic
device than emits light when energized by applying power. The LED die
is mounted to a lead frame(see below) which is encapsulated in an epoxy
lens. The epoxy lens directs the emitted light and protects the LED die
from physical damage. The lead frame provides the electrical
connections, the physical mounting and a thermal heat sink to remove
the heat generated within the LED. A LED display manufacturer must have
an in-depth understanding of LEDs and their properties, as well as use
high-quality components in order to develop effective designs than
stand the test of time.
