The direct current of the output of constant-pressure stable needed for galvanic electricity (alternating current) is converted into lamps and lanterns, realization avoid the phenomenon that glistening or burning lamp.
To solve prior art problem, the technical scheme adopted by the utility model is
A kind of Dimmable LED driving power that waterproof performance is good, comprising: shell, bottom case, circuit board, transformer, rectification
Device, potentiometer, LED drive chip, control handle and screw；The shell both ends are respectively equipped with input connector mouth and output
Connectivity port；The control handle is located at the cover top portion；The bottom case be screwed be connected to it is described outer
Shell bottom；Integral type is equipped with water bar at the top of the bottom case；The circuit board is located inside the water bar；Institute
The circuit board stated and the connectivity port, control handle circuit connection；The circuit board be equipped with transformer, rectifier,
