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

solar powered led street light with auto intensity control wikipedia

Solar street lights are raised light sources which are powered by photovoltaic panels generally mounted on the lighting structure or integrated in the pole itself. The photovoltaic panels charge a rechargeable battery, which powers a fluorescent or LED lamp during the night.

Features

Most solar panels turn on and turn off automatically by sensing outdoor light using a light source.Solar streetlights are designed to work throughout the night. Many can stay lit for more than ....etc

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

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.
