ABSTRACT
High intensity discharge lamp (HID) presently used for urban street light are based on principle of gas discharge, thus the intensity is not controllable by any voltage reduction method as the discharge path is broken. White Light Emitting Diode (LED) based lamps are soon replacing the HID lamps in street light. Thus intensity control is now possible by pulse width modulation based on sensing the movement and density of vehicles. The pulse width becomes very narrow on sensing no movement of vehicles. As the ....etc

Development of street lighting system-based novel high-brightness LED modules
The development of high-power light emitting diode (LED) for street lighting is a continuously evolving topic. greater energy ef ciency, long operating life and light control are the major plus points of this technique. 9LEDM (9-LED module) and adaptive driver based alternative lighting system is shown here. thermal, photometric, power electronics techniques have been used to create the 9 LEDM. The 9LEDM offers a price less than 1$/Watt (W) and luminous ux h ....etc

White Light Emitting Diode (LED) replaces HID lamps in street lighting system to include dimming feature. A microcontroller of 8051 family is used to control the intensity by developing pulse width modulated signals that drives a MOSFET to switch the LEDs accordingly to achieve desired operation.

In the present system, mostly the lighting up of highways is done through High Intensity Discharge lamps (HID), whose energy consumption is high. Its intensity cannot be controlled according to the requirement so there is a need to switch on to an alt ....etc

White light on light-emitting diodes (LED) as a substitute for HID lamps in street lighting system, to include the dimming function. 8051 microcontroller family is used to control the intensity, developing a pulse-width modulated signals that triggers the MOSFET for switching LEDs accordingly to achieve the desired operation.

In this system, mainly covering roads is carried out through the discharge lamps (HID), the energy of which consumption is high. Its intensity may not be managed in accordance with the requirement there is therefore a nee ....etc

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.

FPGA based LED illumination Control System

The resource utilization can be improved by the dynamic reconfiguration technique based on FPGA. The methods and prociples for dynamic reconfiguration is discussed in this article. Here, Xilinx Virtex- FPGA and SMCS Ethernet PHY (Physical Layer Transceiver) is utilised to implement a remote dynamic reconfiguration scheme. The RFDRS (Remote FPGA Dynamic Reconfiguration System) can remotely control the changes freely in the eight LED (Light emitting diodes) lighting modes. This method can be v ....etc
