Abstract

A light-emitting diode lamp is provided. The light-emitting diode lamp includes a light-emitting diode package that includes a light-emitting diode and a circuit substrate on which the light-emitting diode is mounted; a power supply unit that supplies power to the light-emitting diode; a heat radiation member that includes a mounting unit on which the light-emitting diode package is mounted and a cylindrical unit extending from the mounting unit and surrounding the power supply unit to discharge heat generated by the light-emitting diode package; and a heat radiation plastic that surrounds an outer surface of the cylindrical unit.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2011-0089209 filed with the Korean Intellectual Property Office on Sep. 2, 2011, the entire disclosure of which is hereby incorporated by reference. technical field [0003] The present disclosure relates to light emitting diode lamps, and more particularly to small light emitting diode lamps having small non-insulated power supply units. Background technique [0004] A light-emitting diode (LED) is a semiconductor device that realizes various colors of light by constructing a light source with a compound semiconductor PN junction. LEDs have a long life, can be miniaturized, and can be driven at low voltage due to high directivity. Also, the LED is highly resistant to shock and vibration, does not require a preheating time or a complicated driving arrangement, and can be packaged in various types. Therefore, LEDs can be applied to various purposes...
