Abstract: A flow regulator includes a housing portion, a diversion device, an annular seat and an elastic water stop ring. The annular seat, the diversion device and the housing portion are fixedly assembled together. The diversion device includes a periphery wall disposed with diversion holes, a central base within the periphery wall and a deflecting annular wall fixedly connecting the periphery wall and the central base. The external periphery surface of the deflecting annular wall is gradually larger downwardly from the central base to the periphery wall. The central base at least partly extends out of the internal hole of the annular seat. A water flow clearance is formed between the central base and the hole wall of the internal hole of the annular seat. The water flow clearance is disposed above the deflecting annular wall so that water flows out of the flowing clearance and onto the deflecting annular wall.

Abstract: The invention involves a kind of LED straight tube lamp and it falls into the field of lighting technology. The LED straight tube lamp includes a tube, lamp caps that come with contact pins and are located on both ends of the tube, a first rectifying unit and a second rectifying unit that are coupled with the pins on the two ends respectively, a filter unit, and a switch unit that's located between the rectifying unit and the filter unit.
