Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a solar street lamp module. Background Art

[0002] At present, solar road module generally does not have independent lithium battery module. Due to the limited capacity of lithium battery and the heavy weight, the battery capacity cannot be increased unlimitedly on the street light, thus limiting the power of LED light source.
