THE USE OF OPTICAL TOOLS
1. LED (Light Emiting Dioda)
LED is the dioda in Junction
combined with phosphorus,
when the electric current will
produce light

2.LCD (Liquid Crystal Display)
LCD is display tools are widely used as an output
display Digital process, such as Calculator, Clock,
Counter and even monitor the Personal Computer
LCD Calculator Display

3. OPTICAL TOOLS IN SOLAR
CELLS
Solar Cells is photovoltaic
panels, Crystal from the
processing silica sand that is
made in the series-parallel
when the mold is exposed to
sun rays or light TL lamp can
produce electrical energy DC
or AC

4. Photo Resistor/LDR (Light
Dependent resistor)
LDR is a resistor that has a
nature when exposed to
light resistansi value will
be changed
The bright light the small
value resistansi, and light
the dark when the value of
the larger resistansi

5. Photo Dioda
Photo Dioda is a semiconductor
that has a 2 pole, Anoda and
cathode structure PN Junction in
combination with the Optics, that
cash flow is determined by the
size of the light

5. Photo Transistor
NPN
PNP
Photo Transistor is a semi-conductor
that has a 3 electrode, Emitor, Basis
and Colektor, structure and PN
Junction NP or otherwise combined
with Optic, so that the flow of base
flow is determined by the size of the
light intensity
Used
Photo transistors is widely used as a
means of control electronics
associated with the current settings
using the effect light
