1. A light emitting package, comprising:
a light emitting unit emitting an excited beam; and
a light conversion substrate disposed on the light emitting unit,
wherein the light conversion substrate comprises:
a first side part having a first taper; and
a second side part disposed on an edge portion of the light conversion substrate and having a second taper different from the first taper, wherein the second side part exposes a connection terminal of the light emitting unit,
wherein the first taper has a straight line connecting to an upper end and a lower end of the first side part and the second taper has a curved line connecting to an upper end and a lower end of the second side part,
wherein the first taper and second taper are inclined so that an area of the light conversion substrate decreases in the direction away from the light emitting unit,
wherein an angle of the second taper is larger than an angle of the first taper,
wherein the angle of first taper is an angle between the straight line and a vertical segment extending in a vertical direction from the lower end point of the first side part,
wherein the angle of second taper is an angle between an virtual straight line and a vertical segment extending in a vertical direction from the lower end of the second side part, and
wherein the virtual straight line connects the upper end and the lower end of the second side part.
