摘要:
A lighting device including a circuit substrate; a plurality of light sources disposed on the circuit substrate; a reflection layer disposed on the circuit substrate, the reflection layer comprising a plurality of openings where respective light sources are located; a plurality of absorbers disposed at an edge of the reflection layer and at an angle with respect to the reflection layer, wherein first areas aligned with the respective light sources have a greater density of the plurality of absorbers than second areas between the first areas; and an optical sheet disposed on the light sources. In addition, a central axis of a corresponding first area matches a central axis of a corresponding light source.
