摘要:
A light emitting device includes light emitting elements, light-transmissive members, a covering member, at least one first protrusion, and two second protrusions. The light emitting elements are aligned in a first direction. The light-transmissive members are respectively disposed on upper surfaces of the light emitting elements. The covering member includes at least one first covering portion and two second covering portions. The at least one first covering portion is arranged between adjacent ones of the light-transmissive members, and the second covering portions are arranged at distal ends of the light emitting device in the first direction with the light-transmissive members being arranged between the second covering portions. The at least one first protrusion is arranged on an upper surface of the at least one first covering portion and being spaced apart from the light-transmissive members. The second protrusions respectively arranged on upper surfaces of the second covering portions.
