LED LIGHTING APPARATUS HAVING LIGHT COLLECTING STRUCTURE

摘要

PURPOSE: An LED lighting device having a light collecting structure is provided to improve light emitting efficiency of an LED without a complex heat sink unit by regularly maintaining temperature of the LED. CONSTITUTION: An LED lighting device having a light collecting structure includes an LED module(100) of a heat sink structure, a light collecting part(200), a supporting tube(300), an LED module receiving tube(400), and a body tube(500). The LED module includes a heat sink plate(110) and an LED(120). The light collecting part includes a first light collecting lens(210) and a parabolic mirror(220). The supporting tube is formed with a cylindrical shape. The supporting tube is fixed to the heat sink plate of the LED module. The supporting tube is inserted to a top opening part. The LED module receiving tube receives the LED module. The parabolic tube is coupled in a top part of the LED module receiving tube.
