solar street lamps light source selection principle is to select suitable for environmental requirements, high photosynthetic efficiency, long life light source. At the same time in order to improve the efficiency of the use of solar power, choose dc input source as far as possible, avoid because of the introduction of inverter and the power loss ( Due to the small inverter efficiency is lower, LED street lamp, generally less than 80%) 。

common light source types are: the tricolor energy-saving lamp, high-pressure sodium lamp, low voltage sodium lamp, LED, ceramic metal halide lamp, electrodeless lamp, etc. Now) for most of the solar energy light source of lamps and lanterns to comparative analysis:

in the table below for the common characteristics of the dc input source table:

common dc input light feature list

light type luminous efficacy ( lm / w) Color rendering index ( Ra） Color temperature ( K） The average life expectancy ( h） Point,

tricolor energy-saving lamps 60, 80 ~ 90, 2700 ~ 6400, 5000 high photosynthetic efficiency, light color, low cost, wide application

high pressure sodium lamp 100 ~ 120 40, 2000 ~ 2400, 24000 high photosynthetic efficiency, long life, strong sex to penetrate the fog, more suitable for road lighting

low pressure sodium lamp 150 more than 30, 1800, 28000, high light efficiency, long life, through fog and poor

color electrodeless lamp 55 ~ 70, 85, 2700 ~ 6500, 40000 long life, no stroboscopic, good color rendering LED 60 ~ 80, 80, 6500 (

White) 30000 long life, no ultraviolet to infrared radiation, low voltage, there are many kinds of light radiation, adjustable power

ceramic metal halide lamp, 80 ~ 110, 90, 3000 ~ 4000, 12000, long life, high light efficiency, good color rendering.
