A lighting device, comprising: a first light irradiation unit including a first concave reflecting mirror and a first light source provided within the first concave reflecting mirror; and a second light irradiation unit including a second concave reflecting mirror that is smaller than the first concave reflecting mirror and a second light source provided within the second concave reflecting mirror, the second light irradiation unit being disposed more to the light irradiation direction side than the first light source, and being disposed so that the optical axes of the first concave reflecting mirror and the second concave reflecting mirror are the same, wherein a first light blocker adapted to block directly incident light going from the first light source toward an irradiation target is arranged inside of the first light irradiation unit; and a second light blocker being adapted to block directly incident light going from the second light source toward the irradiation target is arranged inside of the second light irradiation unit, wherein the first and second light irradiation units (10, 20) having concave reflecting mirrors (3, 13) and light sources (2, 12) are formed in substantially equivalent shapes, and wherein the entire second light irradiation unit is located inside of the first light irradiation unit, characterized by the second light blocker being made of sheet metal and being integral with support legs supporting the second light irradiation unit, the support legs including vertical leg components, horizontal leg components, upright leg components and connecting leg components. a first light irradiation unit including a first concave reflecting mirror and a first light source provided within the first concave reflecting mirror; and a second light irradiation unit including a second concave reflecting mirror that is smaller than the first concave reflecting mirror and a second light source provided within the second concave reflecting mirror, the second light irradiation unit being disposed more to the light irradiation direction side than the first light source, and being disposed so that the optical axes of the first concave reflecting mirror and the second concave reflecting mirror are the same, wherein a first light blocker adapted to block directly incident light going from the first light source toward an irradiation target is arranged inside of the first light irradiation unit; and a second light blocker being adapted to block directly incident light going from the second light source toward the irradiation target is arranged inside of the second light irradiation unit, wherein the first and second light irradiation units (10, 20) having concave reflecting mirrors (3, 13) and light sources (2, 12) are formed in substantially equivalent shapes, and wherein the entire second light irradiation unit is located inside of the first light irradiation unit, characterized by the second light blocker being made of sheet metal and being integral with support legs supporting the second light irradiation unit, the support legs including vertical leg components, horizontal leg components, upright leg components and connecting leg components.
