Headlight module and headlight device

Abstract

A headlight module (100) includes a light source (1) to emit first light, a first reflecting surface (21a) to reflect partial light (R1a) as part of the first light, thereby forming light (R1b, R1c) in a first light distribution pattern having a cutoff line from light other than the partial light (R1a), and a second reflecting surface (22a) inclined with respect to an optical axis (C1) of the light source (1) so as to be farther from the optical axis (C1) as a distance from the light source along the optical axis (C1) increases. The second reflecting surface (22a) forms light (R3) in a second light distribution pattern by reflecting second light (R2) formed of the partial light (R1a) reflected by the first reflecting surface (21a) and adds the light (R3) in the second light distribution pattern to the light (R1b, R1c) in the first light distribution pattern.
