Light source is an important indicator for solar lights, it's characteristics include High luminous efficiency, Low power consumption and Long service life.

LED light source has a long life, up to 1000000 hours, low working voltage, no inverter, high light efficiency, domestic 50Lm/w, imported 80Lm/w. As technology advances, the performance of LEDs will increase further.

LED light source has the following characteristics:

High luminous efficiency: incandescent light, halogen tungsten light efficiency is 12-24 lumens/watt, fluorescent light 50-70 lumens/watt, sodium light 90-140 lumens/watt, most of the power consumption into heat loss. After improvement, the light efficiency of LED will reach 50-200 lumens/watt, and its light has good monochromaticity and narrow spectrum. It can directly emit colored visible light without filtering. With the progress of technology, the luminous efficiency of LED will be improved greatly.

Low power consumption: LED single transistor power 0.03-0.06 W, using DC drive, single transistor drive voltage 1.5-3.5 volts, current 15-18 mA, fast response, high frequency operation. Under the same lighting effect, the power consumption is one-tenth of an incandescent bulb and one-half of a fluorescent light tube. Its energy-saving effect is obvious.

Long service life: The average life of LED light is 100,000 hours, which can greatly reduce the maintenance cost of lights and save the later maintenance cost of solar street light. At present, most lithium battery solar street lights use LED as light source. During the daytime, the solar light is illuminated on the solar panel, and the light energy is transformed into electric energy stored in the lithium battery. Then the lithium battery provides power for the LED (light emitting diode) of the solar street light at night. LED has the advantages of energy saving, safety, long life and low working voltage. It is very suitable for solar street lights.
