PURPOSE: A lighting device using an LED is provided to reduce weight by including a hollow-shaped housing, thereby improving stability. CONSTITUTION: A hollow unit(11) having a hollow hole is formed in an upper part of a hollow housing member(10). A side unit is formed on an outer girth of the hollow unit. Plural LED modules(20) are mounted on an inner surface of a side unit of the hollow housing member. A hollow cover member(30) covers the inner surface of the side unit. An inclined surface having a slope is formed on one side of an inclined block member(40). Heat sink units(13) for heat emission are formed in an upper part of the hollow housing member. |
