street lights are a very important part of every city's design plan. these lights are used to illuminate sidewalks, roads, and dangerous areas to help keep people safe. they also help people be more aware of what's going on around them at night. adding new street lights involves wiring the new
the first is an ic such as the qx5251. this is a solar battery charger and led driver in a to 94 package. it rectifies the solar input as well as detects when it is dark in order to activate the led. the second is an inductor which the driver uses to boost the voltage from the battery high enough to light the led.
a solar tracker is a device for orienting a solar photovoltaic panel, day lighting reflector or concentrating solar reflector or lens toward the sun. solar power generation works best when pointed directly at the sun, so a solar tracker can increase the effectiveness of such equipment over any fixed position. the solar panels must be perpendicular to the sun's rays for maximum energy generation.
sun chart sun path charts can be plotted either in cartesian (rectangular) or polar coordinates. cartesian coordinates where the solar elevation is plotted on x axis and the azimuth is plotted on the y axis. polar coordinates are based on a circle where the solar elevation is read on the various concentric circles, from 0 to 90 degrees, the azimuth is the angle going around the circle from
