OPTICAL TOOLS

COMPETENCE :IDENTIFICATION OF ELECTRONIC COMPONENT

By. SETYO SMK MUH.3 YOGYA

Teknologi dan Rekayasa

OBJECTIVE

1. KNOW THE KIND OF OPTICAL DEVICE

3. KNOW HOW TO USE OPTICAL TOOLS

2. KNOW THE CHARACTERISTICS OF THE OPTICAL DEVICE



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

A K

Symbol of Dioda



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 LCD for Display LCD for PC



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 DiodaPhoto 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

The bright light of the electric currentw

so

A K



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

Photo transistors is widely used as a means of control electronics associated with the current settings using the effect light

Used


THE END
