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

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

Drainage is the process of interception and removal of water from over, and under the vicinity of the road surface. Drainage can be surface (where water is conveyed on the road surface and drainage channels), or subsurface (water flows underneath the pavement structure).
Surface and subsurface drainage of roads critically affects their structural integrity, life and safety to users, and is thus important during highway design and construction. Road designs therefore have to provide efficient ....etc

automatic street light control using ldr and rtc

The main aim of AUTOMATIC STREET LIGHT CONTROLLER USING RTC project is to build an Automatic Street Light Controller using RTC. This project explains about reducing power consumption on street lights and lights used for advertising boards. In general lot of current is wasted because there is no manual maintenance for switching on and off of these lights at night time. Advertisement board doesn t require power for entire night so we implement this auto street light controller project which will ....etc

ABSTRACT
I2C is a serial interchip communication protocol used for data transfer between chips developed by Philips in order over come the drawback of PCB complexity due to parallel communication which requires 8 pin interface between the chips with the I2C protocol this 8 pins can be reduced to only 2 lines one is data line and one is clock line.
Many devices such RTC, EEPROM, Temperature sensor etc will come with inbuilt I2C engine which helps in reducing the consumption of micro controller pins which is got t ....etc
