PROBLEM TO BE SOLVED: To improve light emitting performance in a lighting device.SOLUTION: A light emitting unit of a lighting device has a light emitting element, a light emitting element substrate on which the light emitting element is mounted, a supporting member for supporting the light emitting element substrate, and a main cover portion covering the light emitting element and transmitting the light emitted from the light emitting element. The main cover portion has a bottom surface portion, and an inclined portion thinner than the bottom surface portion and inclined to the bottom surface portion. Further, the translucent cover includes a diffusion material uniformly dispersed. Thus, the main cover portion includes a light diffusing portion formed on the bottom surface of the main cover portion and diffusing the light, and a light straightening portion inclined to the light diffusing portion and having light straightening performance higher than the light diffusing portion.SELECTED DRAWING: Figure 8 |
