ILLUMINATING DEVICE |
| 摘要 |
In one embodiment, a light emitting device includes: a light source which emits light; a light guide portion which has an emission surface which emits light and a back surface which opposes to the emission surface, and which has at the back surface a reflecting portion which the light emitted from the light source enters and which reflects the entering light toward the emission surface; a heat transfer portion which opposes to the back surface of the light guide portion and is provided with an interval which is a wavelength of the light or more being spaced from the back surface; and a support portion which is provided between the reflecting portion and the heat transfer portion, and which keeps the interval between the light guide portion and the heat transfer portion. |
