ABSTRACT:
When we think about warehouses of today’s industries, the first thought that pops is “THE DARKNESS”. This paper deals with the automatic switching ON and OFF of lights in warehouses using micro processors and sensors. The circuit consists of two optical sensors, counters, phototransistors and relay switches. One optical sensor is installed at the entry door and another optical sensor is installed at the exit door of the ware house. The receiver sections of the sensors ....etc

White LED (Light Emitting Diode) is expected to be the next generation of lamps due to its properties such as high brightness, reliability, low consumption and long life span. In this article , the proposed system for indoor optical wireless duplex channel communication system, as an access to the Internet, utilizing both white LED lights and infrared LEDs is described. The illuminance and power distribution, impulse response, and modulation techniques has been studied in this article. LED lights and receivers design strategies has also been ....etc

BATTERY CHARGERS & BATTERY BANKS
INTRODUCTION
NEED OF BATTERY CHARGERS & BATTERY BANKS
Station battery charger is used to supply the control power to the electrical switchgear like breakers etc which need the DC supply for it’s operation and in case of failure of electrical power the control power is continued to be fed by the battery.
Battery Charger consists of
1) Float Charger
2) Boost Charger
Schemes for Battery Chargers
1) FC & FCBC scheme
2) FCBC & FCBC scheme

The circuit as shown in the figureemploys 14 bi-colour (red andgreen) LEDs having three terminalseach. Different dancing colour patternsare produced using this circuit sinceeach LED can produce three differentcolours. The middle terminal (pin 2) of theLEDs is the common cathode pin which isgrounded. When a positive voltage is appliedto pin 1, it emits red light. Similarly,when positive voltage is applied to pin
It emits green light. And when positive voltageis simultaneously applied to its pins 1and 3, ....etc
