Abstract
An embodiment provides a light emitting unit comprising a refraction unit which is arranged on a body of the light emitting unit; a reflection unit which is arranged on the body so as to be spaced apart from the refraction unit; and a groove with at least a part thereof being arranged within the body and the refraction unit, wherein the height of the refraction unit is 1 to 2.5 times the height of the reflection unit, and the separation distance between the refraction unit and the reflection unit is shortest in the center of a region where the refraction unit and the reflection unit face each other, and largest at the edge.
Claims20
A light-emitting unit comprising;
- a refractor disposed on a body;
- a reflector disposed on the body and spaced apart from the refractor;
- and
- a groove having at least a portion disposed inside the body and the refractor, wherein the refractor has a height ranging from 1 to 2.5 times a height of the reflector, and
- wherein the refractor and the reflector have a space therebetween, and the space has a smallest width at a center of an area in which the refractor and the reflector face each other and a largest width at an edge of the area.
A light-emitting unit comprising;
- a refractor disposed on a body;
