Abstract:
1. A vehicular light emitting diode (LED) lamp comprising: a mounting seat made of heat conductive material and including a front section, with the front section of the mounting seat including front and rear ends spaced from each other in a longitudinal direction, with the front section further including a plurality of mounting grooves spaced from each other in a circumferential direction about the longitudinal direction, with each of the plurality of mounting grooves extending from the front end to the rear end of the front section in the longitudinal direction, with each of the plurality of mounting grooves including a rear wall on the rear end, with each of the plurality of mounting grooves further including a bottom wall extending from the rear wall to the front end of the front section in the longitudinal direction, with each of the plurality of mounting grooves further including two side walls extending outwardly from two sides of the bottom wall and spaced from each other in a width direction perpendicular to the longitudinal direction, with each of the plurality of mounting grooves further including a groove opening opposite to the bottom wall and defined between the two side walls, with each of the two side walls of each of the plurality of mounting grooves including an inner section extending perpendicularly from the bottom wall, with each of the two side walls of each of the plurality of mounting grooves further including an inclined section extending from the inner section toward the groove opening and at an obtuse angle to the inner section; a plurality of carrier plates, with each of the plurality of carrier plates received in one of the plurality of mounting grooves of the mounting seat and made of heat-conductive material, with each of the plurality of carrier plates including first and second ends spaced from each other in the longitudinal direction, with each of the plurality of carrier plates including outer and inner surfaces spaced from each other in a thickness direction perpendicular to the longitudinal and width directions, with each of the plurality of carrier plates carrying at least one LED on the outer surface, with each of the plurality of carrier plates further including two sides spaced from each other in the width direction and having a width in the width direction, with the width of each of the plurality of carrier plates being slightly smaller than a width between the inner sections of the two side walls of an associated one of the plurality of mounting grooves in the width direction, with the inner surface of each of the plurality of carrier plates in contact with the bottom wall of the associated mounting groove, with the two sides of each of the plurality of carrier plates abutting the inclined sections of the two side walls of the associated mounting groove; and a positioning member fixed to the front end of the mounting seat and abutting the second ends of the plurality of carrier plates, with the positioning member including a plurality of through-holes extending in the longitudinal direction, with a screw extending through each of the plurality of through-holes and abutting against the second end of one of the plurality of carrier plates.
