Abstract:
Provided are a light path adjustment block (100), a light module (500), and a manufacturing method for the light module (500) by which productivity can be improved. According to one embodiment, a light path adjustment block (100) comprises: a light-receiving side transparent member that has a first light-receiving surface (111a) that receives light, and a first light emission surface (111b) on the rear of the first light-receiving surface (111a), and that allows at least a portion of the light to pass therethrough; an emission-side transparent member that has a second emission surface (112b) that emits light, and a second light-receiving surface (112a) on the rear of the second emission surface (112b), and that allows at least a portion of the light to pass therethrough; and a gel (103) that fills the space between the first light emission surface (111b) and the second light-receiving surface (112a), that allows at least a portion of the light to pass therethrough, and that has a higher refractive index than air. The inclination of the second light emission surface (112b) can be varied in relation to the first light-receiving surface (111a).
