PURPOSE: An LED lighting device is provided to simplify the structure of coupling a lens with a heat emitting member by using a coupling member integrated with the heat emitting member. CONSTITUTION: An LED lighting device includes coupling members(71A,73A) for coupling a lens unit(50) with a heat emitting member(30). The coupling members are integrated with the lens unit and the heat emitting member respectively. The lens unit includes a light focusing lens(51), a flange unit(53) formed on the light focusing lens, a light emitting unit(55) formed on the flange unit, and a coupling guide unit(57) formed between the bottom of the flange unit and the heat emitting member. The flange unit maintains the lens unit in the heat emitting member. The coupling guide unit supports the coupling between the lens unit and the heat emitting member. |
