Light-emitting module
A light-emitting module (1) includes a light-emitting unit (10) and a rod lens (20). The light-emitting unit (10) outputs a light (11). The rod lens (20) is adjacent to the light-emitting unit (10), and converges the light (11) along an optical axis (100). A radial direction of the rod lens (20) is...

| Zusammenfassung: | A light-emitting module (1) includes a light-emitting unit (10) and a rod lens (20). The light-emitting unit (10) outputs a light (11). The rod lens (20) is adjacent to the light-emitting unit (10), and converges the light (11) along an optical axis (100). A radial direction of the rod lens (20) is parallel to the optical axis (100). A distance between an axis (21) of the rod lens (20) and a light-emitting center (12) of the light-emitting unit (10) along the radial direction is greater than or equal to a focal length of the rod lens (20) along the radial direction. |
