PURPOSE: A heat sink device of an LED module for a lighting device is provided to prevent lifetime reduction of a lighting device and each functional device mounted on a printed circuit board in advance. CONSTITUTION: A heat sink device(40) of an LED module for a lighting device includes a heat sink ring(48), an LED holder(54), a mounting boss(56), and a spring washer. The heat sink ring emits a heat generated from each LED device to outside. An LED mounting part(50) is formed in a top surface of the LED holder. A bottom surface of an LED device(46) is bonded on the LED mounting part. A coupling boss(52) is formed from the center of the bottom surface of the LED holder to a bottom side. A screw part(56a) is formed in an outer circumference of the mounting boss, and is coupled with a heat sink member(58). The spring washer is interposed between a bottom surface of the heat sink ring and a top surface of the heat sink member, and strengthens a coupling state of the heat sink member about the mounting boss. |
