Abstract:
A light emitting module (20) is a light emitting module including a substrate (21), a first area (22) in which LED chips (40) are mainly arranged and mounted in a longitudinal direction of the substrate in an area on one side of the longitudinal direction, a second area (23) in which non-light emitting components (30) are mainly mounted in an area on another side of the longitudinal direction of the substrate and a notch portion (24) which is between the first area (22) and the second area (23) and formed on the substrate. The non-light emitting components (30) are mountable across the notch portion (24) between the first area (22) and the second area (23). Further, the substrate (21) is separable into the first area (22) and the second area (23) by the notch portion (24). Furthermore, the first area (22) after separation is formed to be connectable consecutively with another light emitting module (20B) in the longitudinal direction.
