Abstract
A lighting device includes a light source line, a light guide plate, and a wavelength converting member. The light source line includes an inner light source and outer light sources. The inner light source is disposed in the middle and configured to emit primary light rays in a predefined wavelength range. The outer light sources are disposed outer than the inner light source and configured to emit primary light rays and complementary color light rays. The light guide plate includes a light entering surface and a light exiting surface. The wavelength converting member contains first phosphors configured to emit secondary light rays in a wavelength range different from the wavelength range when excited by the primary light rays. The wavelength converting member is disposed to cover the light exiting surface and configured to pass some of the primary light rays and to release planar light.
