The light-emitting module is mounted on a main surface of the mount, and the substrate holder covers a portion of the light-emitting module and is connected with the mount. The light-emitting module includes a substrate, a plurality of light-emitting elements, a sealant and a padding. The padding is provided on a first main surface of the substrate. The light-emitting module is mounted on the main surface of the mount such that a second main surface of the substrate comes into contact with the main surface of the mount, and the light-emitting module is fixed to the mount by pressure applied from the substrate holder via the padding brought into contact with the substrate holder. The padding is made of a same material as the sealant. ## Claims ### Claim 1 A lighting device comprising: a mount; a light-emitting module mounted on a main surface of the mount; a substrate holder covering a portion of the light-emitting module and connected with the mount, wherein the light-emitting module includes: a substrate; a plurality of light-emitting elements mounted on a first main surface of the substrate; a sealant located on the first main surface of the substrate and sealing the plurality of light-emitting elements; and a padding located on the first main surface of the substrate, the light-emitting module is mounted on the main surface of the mount such that a second main surface of the substrate, which is on the opposite side of the substrate as the first main surface, comes into contact with the main surface of the mount, and the light-emitting module is fixed to the mount by pressure applied from the substrate holder via the padding brought into contact with a surface of the substrate holder, the surface facing toward the main surface of the mount, and the padding is made of a same material as the sealant. ### Claim 2 (depends on 1) The lighting device of claim 1, wherein in plan view of the light-emitting module, the padding surrounds an area of the first main surface of the substrate, and the plurality of light-emitting elements are mounted on the area surrounded by the padding. ### Claim 3 (depends on 1) The lighting device of claim 1, wherein the padding is composed of at least three padding portions separated from each other. ### Claim 4 (depends on 3) The lighting device of claim 3, wherein in plan view of the light-emitting module, a center point of the plurality of light-emitting elements is located within an area defined by three line segments connecting any three portions out of the padding portions with each other. ### Claim 5 (depends on 3) The lighting device of claim 3, wherein the plurality of light-emitting elements are grouped in rows, the sealant is composed of a plurality of sealant portions separated from each other and sealing the rows in one-to-one correspondence, and each of the plurality of sealant portions is connected with a longitudinal end of a different one of the padding portions. ### Claim 6 (depends on 1) The lighting device of claim 1, wherein the padding is connected with the sealant. ### Claim 7 (depends on 1) The lighting device of claim 1, wherein the substrate holder has a tapered hole provided above the plurality of light-emitting elements so as not to cover the plurality of light-emitting elements, the tapered hole tapers toward the light-emitting module, and a surface of a side wall of the tapered hole is a reflective surface that reflects light from the plurality of light-emitting elements. ### Claim 8 (depends on 1) The lighting device of claim 1, wherein under a condition that the light-emitting module is not receiving pressure from the substrate holder, a maximum height of the padding with reference to the first main surface of the substrate is equal to or larger than a maximum amount of deflection in the substrate. ### Claim 9 (depends on 1) The lighting device of claim 1, wherein under a condition that the light-emitting module is not receiving pressure from the substrate holder, the padding has a smaller maximum height than the sealant with reference to the first main surface of the substrate. ### Claim 10 (depends on 1) The lighting device of claim 1, wherein the substrate of the light-emitting module is made of a ceramic containing material. ### Claim 11 A light-emitting module located between a mount and a substrate holder and fixed to the mount, the light-emitting module comprising: a substrate; a plurality of light-emitting elements mounted on a first main surface of the substrate; a sealant located on the first main surface of the substrate and sealing the plurality of light-emitting elements; and a padding located on the first main surface of the substrate, wherein the light-emitting module is mounted on a main surface of the mount such that a second main surface of the substrate, which is on the opposite side of the substrate as the first main surface, comes into contact with the main surface of the mount, and the light-emitting module is fixed to the mount by pressure applied from the substrate holder via the padding brought into contact with a surface of the substrate holder, the surface facing toward the main surface of the mount, and the padding is made of a same material as the sealant.
