I NTRODUCTION TO “Z-LED LIGHTS” Studies different types of LEDs Designing of LED Products Supplying LED Products to malls, restaurants, hospitals, housing projects, street lights and hoardings etc. 2

LED ?? Light emitting diodes Near future bulb replacements of CFLs & Incandescent bulbs Semiconductor device which conducts electricity only in one direction Tiny light bulbs No filament, no gases, no Hg, no heavy metal used Symbol : 3

H ISTORY OF LED M id 1920s - Oleg Vladimirovich Losev (Russian) – first LED 1962 – Nick Holonyak Jr. – first practical LED (Red) T.P. Pearsall – first high efficiency, high brightness LEDs for optical fiber telecommunications Initial LEDs very costly First commercial LEDs - “seven-segment displays” Time by Time – Radios, TVs, Watches, Calculators, Mobiles etc. 4
