| description | A light emitting device includes: a substrate; one or more LED (light emitting diode) elements mounted on a substrate; and a radiator unit made of metal paste and arranged on a rear surface opposite to a principal surface on which the one or more LED elements are mounted. The height Ta of the radiator unit from a rear surface is less than thickness Tb of substrate. |
