Plurality of light-emitting devices, and light-emitting module

A plurality of light-emitting devices adapted to be transferred to one customer or transferred separately to different customers, the plurality of light-emitting devices comprising:

• a first light-emitting device including
• a first package having a first outer shape,
• a plurality of first semiconductor laser elements sealed in the first package, and
• a first lens member fixed to the first package and having a plurality of lens surfaces, a number of the lens surfaces of the first lens member being the same as the number of the first semiconductor laser elements, each of the lens surfaces corresponding to a respective one of the first semiconductor laser elements and being configured to transmit light emitted from the respective one of the first semiconductor laser elements, and
• a second light-emitting device including
• a second package having the first outer shape,
• one or more second semiconductor laser elements sealed in the second package, and
• a second lens member fixed to the second package and having one or more lens surfaces, a number of the one or more lens surfaces of the second lens member being the same as the number of the one or more second semiconductor laser elements, each of the one or more lens surfaces corresponding to a respective one of the one or more second semiconductor laser elements and being configured to transmit light emitted from the respective one of the one or more second semiconductor laser elements, wherein
• a number of the one or more second semiconductor laser elements is less than a number of the first semiconductor laser elements,
• one of the first semiconductor laser elements is configured to emit first light having a color different from a color of light emitted from any of the one or more second semiconductor laser elements, and
• a curvature of one of the lens surfaces of the first lens member configured to transmit the first light emitted from the one of the first semiconductor laser elements is the same as a curvature of one of the one or more lens surfaces of the second lens member.
