THE INTERIOR ILLUMINATING LAMP WHERE THE LIGHT-EMITTING DIODE IS HAD

摘要

PURPOSE: An indoor lamp with a light emitting diode is provided to prevent damage to a light emitting diode and lengthen service life of the light emitting diode by including a dissipation fin and a heat sink. CONSTITUTION: A main body(2) comprises outlet holes(22), a female screw thread(23). A receiving part is formed inside the main body. A connecting rod(10) comprises a male screw thread(10a) fixed with the female screw thread. A heat sink(3) is integrated with the inner part of the main body. A light emitting diode(4) is installed on the inner side of the main body. A lens(6) is formed inside the main body. A PCB circuit board(7) is connected to the power supply connector and is electrically grounded with the light emitting diode. Through-holes are formed in a cap(9) to release heat of the heat sink.
