A Light emitting diodes (LEDs) have gained broad recognition as the ubiquitous little lights that tell us that our monitors are on, the phone is off the hook or the oven is hot semiconductor.

The basic principle behind the emission of light is that: When charge carrier pairs recombine in a semiconductor with an appropriate energy band-gap generates light. In a forward biased diode, little recombination occurs in the depletion layer. Most occurs in a few microns of either P- region or N ?region, depending on which one is lightly doped.

Abstract

Here, students learn how solid state lighting technology can improve the lives of people in the developing world, making their evenings more productive and safer. In the laboratory, the students design a portable, solar-charged, LED lamp that can provide two hours of reading light. In the process, they learn about basic circuits, the engineering design cycle, and light. They also compare the efficiency, durability, and cost of lighting technologies.

Solid State Hard Disk


INTRODUCTION ABOUT SOLID STATE HARD DISK

A solid-state drive (SSD) is a data storage device that uses solid-state memory to store persistent data. A SSD uses SRAM or DRAM .

The original usage of the term solid-state refers to the use of semiconductor devices rather than electron tubes.

With no moving parts, solid-state drives are less fragile than hard disks and are also silent

Solid-State Welding Processes


Cold Welding

Pressure is applied to the workpieces through dies or rolls

Preferably both work pieces should be ductile

The work pieces should cleaned thoroughly

Can not join dissimilar metals

SOLID STATE STABILISER

ABSTRACT

The SOLID STATE STABILISER is an electronic device intended to provide a stable 230 V- 50 Hz output. The main purpose is to provide a constant voltage having a constant frequency. The input is taken from a common power supply of 230 V-50 Hz. The obtained voltage is converted to higher frequency and stepped up using a small ferrite core transformer. It is then converted to a lower frequency and stabilized to get the required regulated output voltage.
