why use solar street lamps LED as light source? As is known to all, solar LED street lamp light source is usually little or there is no high pressure sodium lamp and incandescent lamp light source, is this why? Reasons mainly include the following: 1, the voltage: LED voltage is dc 12 v or 24 v, but generally high pressure sodium lamp and energy-saving lamps light source voltage is 220 v, so the voltage is not 2, smooth effect: it is the most important, the LED lighting is normal sodium lamp 2 times, four times as great as that of general energy-saving lamps, 6 - is incandescent lamp Eight times, so tremendous improvements in energy efficiency, with the highest photosynthetic efficiency from a minimal wattage 3, service life, the service life of the LED is unmatched by any other light sources, average service life of more than 10 years, or even the service life of 15 years to 20 years. It is because the LED has so many advantages, the LED street light, so LED into the absolute solar street lamps light source now
