Abstract

A small-sized lighting device can achieve wider light distribution patterns. The lighting device can include a semiconductor light emitting element configured to emit light from a first face and a second face thereof. A mounting substrate can be provided on which the semiconductor light emitting element is mounted. Light emitted from the second face can transmit through the mounting substrate, and a first optical system can be provided and configured to impart a first light distribution pattern to the light emitted from the first face of the semiconductor light emitting element. A second optical system can be provided and configured to impart a second light distribution pattern to light emitted from the second face of the semiconductor light emitting element.
