a light source mounted on the substrate; and an optical device disposed on the light source, wherein the optical device comprises: a first surface disposed above the light source; a second surface disposed opposite to the first surface and through which light generated in the light source is emitted externally; and a support disposed on the first surface and fixed to the substrate, wherein the support includes a protrusion protruding around a side surface thereof, wherein the protrusion has a structure extending from a portion spaced apart from the first surface in a lateral direction substantially perpendicular to a longitudinal direction of the support; and wherein the protrusion is spaced apart from an upper surface of the substrate and disposed above the substrate. ### Claim 2 (depends on 1) The light source module of claim 1, wherein the protrusion is formed of the same material as the support and formed integrally with the support. ### Claim 3 (depends on 1) The light source module of claim 1, wherein the protrusion has a ring shape including a through-hole, and is inserted into and fixed to the support through the through-hole. ### Claim 4 (depends on 1) The light source module of claim 1, wherein a portion of the second surface convexly protrudes in a moving direction of light, and a central portion thereof through which an optical axis of the light source passes is concavely recessed toward the light source to have an inflection point. ### Claim 5 (depends on 1) The light source module of claim 1, wherein the second surface includes a first curved surface having a concavely curved portion recessed along an optical axis toward the light source, and a second curved surface having a convexly curved portion extending continuously from an edge of the first curved surface to the edge of the first surface. ### Claim 6 (depends on 1) The light source module of claim 1, wherein the first surface includes a depression recessed in a light-emitting direction in a center portion thereof through which an optical axis of the light source passes. ### Claim 7 (depends on 6) The light source module of claim 6, wherein the depression is disposed to face the light source above the light source, and a cross-sectional area of the depression exposed on the first surface is greater than an area of a light-emitting plane of the light source. ### Claim 8 A light source module, comprising: a substrate; a light source mounted on the substrate; and an optical device disposed on the light source, wherein the optical device comprises: a first surface facing the light source; a second surface disposed opposite to the first surface and through which light generated in the light source is emitted externally; and a first support disposed on the first surface, and a second support disposed on an end portion of the first support and fixed to the substrate by an adhesive, wherein the second support includes a protrusion protruding around a side surface thereof. ### Claim 9 (depends on 8) The light source module of claim 8, wherein the protrusion has a structure extending from an end portion of the second support in contact with the first support in a lateral direction substantially perpendicular to a longitudinal direction of the second support. ### Claim 10 (depends on 8) The light source module of claim 8, wherein the second support includes a fastening hollow into which the first support is partially inserted and fastened, on a surface in contact with the first support. ### Claim 11 (depends on 8) The light source module of claim 8, wherein the second support is formed of a resin or a metal. ### Claim 12 (depends on 8) The light source module of claim 8, wherein the adhesive includes an epoxy adhesive or a solder cream. ### Claim 13 (depends on 8) The light source module of claim 8, wherein the light source is a light-emitting diode (LED) chip or an LED package in which the LED chip is mounted. ### Claim 14 A light source module, comprising: a substrate; a light source mounted on a top surface of the substrate; and an optical device disposed above the light source, wherein the optical device comprises: a first surface facing the light source; a second surface disposed opposite to the first surface and through which light generated in the light source is emitted externally; and a support with an upper end disposed on the first surface and a lower end mounted to the top surface of the substrate, wherein the support has a lower portion having a bar-shaped structure, an upper portion having the bar-shaped structure, and a protrusion at a middle portion wherein the protrusion extends in a lateral direction away from the bar-shaped structure. ### Claim 15 (depends on 14) The light source module of claim 14, wherein the lower end of the support is fixed to the top surface of the substrate by an adhesive. ### Claim 16 (depends on 14) The light source module of claim 14, wherein the protrusion has a surface substantially parallel to the top surface of the substrate. ### Claim 17 (depends on 14) The light source module of claim 14, wherein the protrusion has an inclined surface toward the top surface of the substrate. ### Claim 18 (depends on 14) The light source module of claim 14, wherein the support comprises at least two supports.
