Description
Technical field
The invention belongs to a kind of driving equipment, and in particular to a kind of LED tunnel lamp driver based on FAN527B.
Background technology
LED illumination has low energy consumption, the environment-friendly and green lighting characteristics without ultraviolet, without infra-red radiation, mercury-free, at present by
Step is generalized to indoor and outdoors illumination application field.Tunnel illumination whole day works for 24 hours, is shown using LED tunnel lamp energy-saving effect
Write, using gradually increasing.But when being passed through without car, also total power illuminates these Tunnel Lamps, wastes electric energy unavoidably, subtracts with energy-conservation
Row, green theory are runed counter to.In order to save, part Tunnel Lamp is controlled using the period, the total power at wagon flow peak, in car
Flow halves power illumination when few.Although this technology can realize energy-saving effect, it is unfavorable to traffic safety, is not inconsistent
Close people-oriented, safety first theory.

Deficiency.
In order to achieve the above object, the technical solution adopted in the present invention is：
A kind of LED tunnel lamp driver based on FAN527B, it is by full-wave rectifying circuit, DC/DC translation circuits, output rectification
Filter circuit and PWM controller circuit composition, described full-wave rectifying circuit are connected with DC/DC translation circuits, DC/DC conversion electricity
Road connects output rectifier and filter, output rectifier and filter connection error feedback circuit, error feedback circuit connection PWM controls
Device circuit processed.
Described driver has FAN527B chips.
Described driver has TMS101 chips.
Described driving implement has power switch pipe.
Described driver has bridge rectifier.
The present invention is simple in construction, and easy to use, technology is reasonable., in tunnel without car by when retain the LED in often bright loop
Lamp is lighted, and saves the energy.Have car by when automatically open up whole LED lamps, ensure sufficiency of illumination, safe and reliable.
