LIGHTING DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18461774 titled 'LIGHTING DEVICE

Simplified Explanation

The lighting device described in the abstract includes a first light source portion, a light guide, and a second light source portion. The light guide emits a first light including the guided light to illuminate an object, while the second light source portion emits a second light to also illuminate the object independently of the first light source portion and the light guide.

The lighting device includes a first light source portion that emits light to illuminate an object.
The light guide guides the light emitted from the first light source portion in a longitudinal direction and emits a first light to illuminate the object.
A second light source portion emits a second light to illuminate the object independently of the first light source portion and the light guide.
