PROBLEM TO BE SOLVED: To provide an inner surface reflection type lighting apparatus of high efficiency heat radiation and light-emission.SOLUTION: An inner surface reflection type lighting apparatus 10 includes: light-emitting means 12 which is equipped with a lamp bottom portion 122 and a light-emitting portion 124; a reflection material 14 which is coupled with the light-emitting portion 12, equipped with a fixed portion 142 and a reflecting portion 144, positioned on one side of the fixed portion 142, and forms a reflection curved surface 1442 whose surface forms a first reflection layer 1444; and a cup portion 16 which stores the light-emitting means 12 and the reflection material 14, is equipped with a second reflection layer 162, a first storage space 164, and a fixed groove 166, formed with the second reflection layer 162 on an inner wall of the cup portion 16, uses the fixed groove 166 for fixing the fixed portion 142, and exposes the reflection portion 144 to the storage space 164. By reflecting to the second reflection layer 162 through a first reflection layer 1444, light L is emitted from the cup portion 16.SELECTED DRAWING: Figure 1 |
