PURPOSE: An LED(Light Emitting Diode) flood light is provided to uniformly diffuse light emitted in an LED by arranging a convex lens in an optical source part. CONSTITUTION: A heat dissipation housing(30) comprises a main body member(31) and a free convection radiating unit(33). A light source installation unit is formed in the main body member. The free convection radiating unit comprises a plurality of heat-radiating fins and a heat dissipation frame. A plurality of heat radiation fins are projected from the main body member with a radial shape. The heat dissipation frame interlinks the leading end of the heat radiation fins. A plurality of air passages(335) are formed between the main body member and the heat dissipation frame to the vertical direction. A heat dissipation reflector(50) executes a photo induction and heat dissipation function. |
