Abstract
A light source module includes a substrate; a light source disposed on the substrate; a lens assembly configured to transmit light transferred from the light source; and an optical barrier having a shape which surrounds the light source to block light transferred from the light source.
Claims8
A light source module comprising:
- a substrate;
- an optical sensor disposed on the substrate and configured to receive light transferred from a light source;
- a lens assembly configured to transmit light, transferred from the light source, so as to transfer the light to the optical sensor;
- an optical barrier configured to block light transferred from the light source;
- wherein a light transmission layer is formed between the optical barrier and the optical sensor, and
- a side fill, which blocks light of a predetermined wavelength band, is applied to a path through which light is transferred to the light transmission layer.
