Abstract:
1. A lighting device configured to emit light in an illumination direction comprising: a substrate; a lens opposed to the substrate, the lens having an outer peripheral surface and being provided with a first lens cut portion formed on a rear surface of the lens with respect to the illumination direction of the lighting device such that the first lens cut portion faces the substrate, the substrate and the lens defining a lighting chamber there between; a light source disposed within the lighting chamber and having a main optical axis substantially aligned with the illumination direction, the light source configured to emit light beams at certain angles with respect to the main optical axis, a first portion of the light beams being reflected by the first lens cut portion and projected in the illumination direction; and a reflecting portion configured to reflect at least a portion of the light beams, the reflecting portion located at a front side of the substrate with respect to the illumination direction, wherein the lens includes a reflection surface configured to reflect light beams that are emitted from the light source and which travel within the lens and enter the outer peripheral surface of the lens, the reflection surface being located substantially at the outer peripheral surface of the lens, and the reflecting portion configured to reflect light beams reflected by the reflection surface.
