Description
Technical field
The present invention relates to a kind of circuit control system, specifically a kind of LED street lamp control system.
Background technology
Along with the progress of LED manufacture technology and battery technology, high brightness (HB) LED is widely used in various luminaire at present, and its light output (luminous efficiency) generally measures in units of lumens/watt, has been over the luminous efficiency of fluorescent lamp. And when adopting high power capacity, single-unit Li+ battery to drive high efficiency LED light source, owing to cell voltage is only 3V to 4V, it is necessary to solve Power convert problem.
