| 主权项 | 1. A lighting device comprising: 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 the plurality of absorbers have a greater density at first areas aligned with the respective light sources than at second areas between the first areas; and an optical sheet disposed on the light sources, wherein a central axis of a corresponding first area matches a central axis of a corresponding light source. | ||
