Abstract
A light emitting module includes at least one light source, a light guide member having a demarcating groove configured to demarcate at least one light emitting region, and at least one light source arrangement part located in each of the at least one light emitting region and accommodating a light source, a first light-reflecting member disposed in the demarcating groove, and a wavelength converting member covering an upper surface of the light guide member.
Claims21
A light emitting module comprising:
- at least one first light source;
- a light guide member comprising
- a demarcating groove configured to demarcate at least one first light emitting region, and
- at least one first light source arrangement part provided in the at least one first light emitting region and accommodating a corresponding one of the at least one first light source;
- a wavelength converting member covering an upper surface of the light guide member;
- and
- at least one light adjusting member located in a region directly above a corresponding one of the at least one first light source,
- wherein the at least one light adjusting member is configured to reflect a portion of light emitted from the corresponding one of the at least one first light source and to transmit another portion of the light emitted from the corresponding one of the at least one first light source, and
- wherein the wavelength converting member is located on or above an upper surface of the at least one light adjusting member.
