Abstract: A lighting device includes a light board and a light dimmer circuit. The light board includes multiple first light emitting elements and second light emitting elements. The first light emitting elements are disposed in a first area of the light board. The second light emitting elements are disposed in a second area of the light board. The light dimmer circuit is configured to drive the second light emitting elements to generate flickering lights from the second area of the light board, and is configured to drive the first light emitting elements to generate non-flickering lights from the first area of the light board.

Abstract: A lighting device includes a board, first light emitting elements and second light emitting elements. The first light emitting elements emit lights in a first spectral range. The second light emitting elements emit lights in a second spectral range. The second spectral range is narrow than the first spectral range. The first light emitting elements are disposed in at least one first area of the board, and the second light emitting elements are disposed in second areas of the board. The at least one first area and the second areas are alternatively arranged on the board.
