ABSTRACT:
A light emitting element suitable for a blue light lamp in a signal light apparatus is provided. The group III nitride compound semiconductor light emitting element includes a first light emitting layer for emitting a first light having a blue light and a second light emitting layer for emitting a second light having a green light. The first light and the second light are combined to provide a third light having a blue-green light synthesized from the first light and the second light.
