DETAILED DESCRIPTION OF THE INVENTION

[0009] A method for manufacturing a light-emitting module and a light-emitting module according to an embodiment of the present disclosure will be described in detail with reference to the drawings. However, the embodiments shown below are illustrative of a method for manufacturing a light-emitting module and a light-emitting module that embody the technical concept of the present embodiment, and are not limited thereto. Furthermore, unless otherwise specified, the dimensions, materials, shapes, and relative arrangements of components described in the embodiments are not intended to limit the scope of the present disclosure to those specific embodiments, and are merely illustrative examples. The size, positional relationships, etc. of components shown in each drawing may be exaggerated for clarity. In the following description, identical names and symbols indicate identical or similar components, and detailed descriptions will be omitted as appropriate. An end view showing only the cut surface may be used as a cross-sectional view.

[0010] In the drawings shown below, directions may be indicated by the X-axis, Y-axis, and Z-axis, but the X-axis, Y-axis, and Z-axis are mutually orthogonal directions. The first direction X along the X-axis and the second direction Y along the Y-axis indicate directions along the light-emitting surface of the light-emitting unit included in the light-emitting module according to the embodiment. The Z direction along the Z-axis indicates a direction orthogonal to the light-emitting surface. In other words, the light-emitting surface of the light-emitting unit is parallel to the XY plane, and the Z-axis is orthogonal to the XY plane.

[0011] The direction in which the arrow points in the first direction X is referred to as the +X side, and the side opposite the +X side is referred to as the -X side. The direction in which the arrow points in the second direction Y is referred to as the +Y side, and the side opposite the +Y side is referred to as the -Y side. The direction in which the arrow points in the Z direction is referred to as the +Z side, and the side opposite the +Z side is referred to as the -Z side. In the embodiment, the light-emitting unit provided in the light-emitting module emits light in the +Z side, for example. However, the above directional expressions merely describe the relationship between relative positions, orientations, directions, etc., and do not necessarily correspond to the relationship during use. Furthermore, these directions are unrelated to the direction of gravity. Furthermore, the above directional expressions do not limit the orientation of the light-emitting module during use, and the orientation of the light-emitting module is arbitrary.

[0012] In this specification, the surface of an object when viewed from the +Z side is referred to as the "top surface," and the surface of an object when viewed from the -Z side is referred to as the "bottom surface." In the following embodiments, "along the X-axis, Y-axis, and Z-axis" includes the object being tilted within a range of ±10° relative to these axes. In this embodiment, "orthogonal" may include an error of ±10° relative to 90°. Furthermore, "disposed" is not limited to direct contact, but also includes indirect disposition, for example, via another member.

[0013] In this specification or the claims, when there are multiple elements of a certain type and they are to be expressed separately, the elements may be distinguished by prefixing them with "first," "second," etc. Furthermore, there may be cases where the objects distinguished in this specification and the claims are different.

[0014] [First embodiment] <Configuration of the Light-Emitting Module According to the First Embodiment> The configuration of the light emitting module according to the first embodiment will be described with reference to Fig. 1 to Fig. 3. Fig. 1 is a schematic top view of the light emitting module 100 according to the first embodiment. Fig. 2 is a schematic cross-sectional view taken along line II-II in Fig. 1. Fig. 3 is a schematic cross-sectional view showing the configuration of the light source 1 in the light emitting module 100. Fig. 3 shows a cross section of the light source 1 taken along line II-II in Fig. 1.

[0015] As an example, light emitting module 100 is a light emitting module used as a flash light source in an imaging device mounted on a smartphone. Note that imaging devices include cameras that capture still images and video cameras that capture moving images.

[0016] The light-emitting module 100 includes a substrate 2, a light source 1 disposed on the upper surface 23 of the substrate 2, and an optical member 3. The optical member 3 includes a lens 31, a support portion 32 that supports the lens 31, and a leg portion 33 disposed outside the support portion 32 in a top view. The leg portion 33 includes a first magnet portion 330 on at least a portion of a lower surface 331. In the example shown in FIG. 2 , the leg portion 33 includes the first magnet portion 330 on the entire lower surface 331 of the leg portion 33. In other words, the lower surface of the leg portion 33 is formed by the first magnet portion 330. The lower surface 331 of the leg portion 33 of the optical member 3 is disposed on the upper surface 23 of the substrate such that the lens 31 faces the light source 1.

[0017] The first magnet portion 330 is composed of a permanent magnet. It is preferable to use a bonded magnet, which is a mixture of powdered magnetic material and resin material, for the first magnet portion 330. The first magnet portion 330 is a part formed, for example, by mixing a magnetic material with resin and molding it. The magnetic material is a material that has magnetic properties. The first magnet portion 330 contains a magnetic material, and has the function of a magnet when the magnetic material is magnetized after molding. The first magnet portion 330 is provided on the optical member 3 so as to be in a predetermined positional relationship with the lens 31.

[0018] Here, the manufacturing process of the light emitting module 100 includes a step of arranging the lower surface 331 of the leg portion 33 of the optical member 3 on the upper surface 23 of the substrate 2 so that the lens 31 faces the light source 1. For example, in this arranging step, image recognition technology and positioning control technology can be used to position the light source 1 and the lens 31. However, repeating the image recognition process and positioning control until positioning is complete may increase the lead time. Note that the image recognition technology is a technology that recognizes the relative position of the light source 1 and the lens 31 based on captured images of the light source 1 and the lens 31. The positioning control technology is a technology that controls the relative position of the light source 1 or the lens 31 based on the image recognition results. If it takes a long time to position the light source 1 and the lens 31, the manufacturing efficiency of the light emitting module 100 decreases.

[0019] In the manufacturing method of the light-emitting module 100 according to this embodiment, the optical member 3 can be autonomously moved to a predetermined position by utilizing the mutual attractive force (i.e., magnetic force) between the second magnet portion disposed outside the optical member 3 and the first magnet portion 330 disposed on the optical member 3. Specifically, in the step of disposing the optical member 3 on the substrate 2, the second magnet portion disposed on either the substrate 2 or the opposite side of the optical member 3 relative to the substrate 2 attracts the first magnet portion 330, thereby autonomously moving the optical member 3. If the first magnet portion 330 is previously positioned to have a predetermined positional relationship with the lens 31 and the second magnet portion is previously positioned to have a predetermined positional relationship with the light source 1, the lens 31 is autonomously positioned relative to the light source 1 by the autonomous movement of the optical member 3. The optical member 3 is then fixed at the positioned position by magnetic force.

[0020] Positioning the lens 31 relative to the light source 1 means that the optical axis 31C of the lens 31 and the light source axis 1C of the light source 1 are approximately aligned. The light source axis 1C is an axis that passes through the center of the light-emitting surface 11 in a top view and extends in a direction along the optical axis 31C of the lens 31. In the example shown in FIGS. 1 and 2, the light source axis 1C and the optical axis 31C are aligned and overlap, so the symbols for the light source axis 1C and the optical axis 31C are written together. Note that "approximately aligned" between the optical axis 31C of the lens 31 and the light source axis 1C of the light source 1 includes, within an acceptable range, a deviation that has little effect on the performance of the lens 31 (for example, an error caused by material tolerances or mounting tolerances), although this depends on the shape of the lens 31 and the sizes of the lens 31 and the light source 1.

[0021] In the light emitting module 100, the light source 1 and the lens 31 can be positioned without performing image recognition processing and positioning control. Furthermore, the image recognition processing and positioning control can be simplified. This reduces the time required for positioning, and increases the manufacturing efficiency of the light emitting module 100. As a result, in this embodiment, it is possible to provide a light emitting module 100 with high manufacturing efficiency.

[0022] In the example shown in FIG. 1, the outer shape of the light emitting module 100 when viewed from above is approximately rectangular. The outer shape of the light source 1 when viewed from above is approximately rectangular. The light source 1 includes a light emitting surface 11. The light emitting surface 11 refers to the main light extraction surface of the light source 1. The outer shape of the light emitting surface 11 when viewed from above is approximately rectangular. However, the shapes of the light emitting module 100, the light source 1, and the light emitting surface 11 when viewed from above may be approximately circular, approximately elliptical, approximately polygonal, or the like. Furthermore, the number of light emitting surfaces 11 included in the light source 1 is not limited to one, and may be two or more.

[0023] (Light source 1) 3 is disposed on the +Z side surface of the substrate 2, with its upper surface serving as a light-emitting surface 11 and its surface opposite to the light-emitting surface 11 serving as a mounting surface. The light source 1 includes a light-emitting element 12, a wavelength conversion member 14 disposed on the light-emitting element 12, and a light-shielding member 15 that exposes the upper surface of the wavelength conversion member 14 and covers the side surfaces of the light-emitting element 12 and the wavelength conversion member 14. In other words, the side surfaces of the light-emitting element 12 and the wavelength conversion member 14 are each covered by the light-shielding member 15. This configuration reduces light leaking from the side surfaces of the light-emitting element 12 and the wavelength conversion member 14, and allows light from the light-emitting element 12 to be irradiated onto a desired area from the light-emitting surface 11 of the light source 1 via the wavelength conversion member 14.

[0024] The light emitting element 12 has positive and negative electrodes 13 on the surface opposite to the light emitting surface 11 (that is, the bottom surface).

[0025] The light emitting element 12 includes various semiconductors such as III-V group compound semiconductors and II-VI group compound semiconductors. X Al Y Ga 1-X-YIt is preferable to use a nitride-based semiconductor such as InN (0≦X, 0≦Y, X+Y≦1), and InN, AlN, GaN, InGaN, AlGaN, InGaAlN, etc. can also be used. The light-emitting element 12 is, for example, an LED or an LD (laser diode). From the viewpoints of luminous efficiency and excitation of the wavelength conversion material described below, the emission peak wavelength of the light-emitting element 12 is preferably 400 nm or more and 530 nm or less, more preferably 420 nm or more and 490 nm or less, and even more preferably 450 nm or more and 475 nm or less.

[0026] The wavelength conversion member 14 is, for example, a substantially rectangular member when viewed from above. The wavelength conversion member 14 is provided to cover the upper surface of the light-emitting element 12. The wavelength conversion member 14 contains a wavelength conversion substance that converts the wavelength of at least a portion of the light from the light-emitting element 12. The wavelength conversion member 14 can be made of a translucent resin material or an inorganic material such as ceramics or glass. Examples of resin materials that can be used include thermosetting resins such as silicone resin, silicone-modified resin, epoxy resin, epoxy-modified resin, and phenolic resin. Silicone resin or its modified resin, which has excellent light resistance and heat resistance, is particularly suitable. Here, translucency preferably means that 60% or more of the light from the light-emitting element 12 is transmitted. The wavelength conversion member 14 can also be made of a thermoplastic resin such as polycarbonate resin, acrylic resin, methylpentene resin, or polynorbornene resin. For example, the wavelength conversion member 14 may be a resin material, ceramics, glass, or the like containing the wavelength conversion substance, or a sintered body of the wavelength conversion substance. Furthermore, the wavelength conversion member 14 may contain a light diffusing material described below in addition to the above resin. Alternatively, the wavelength conversion member 14 may be a multilayer structure in which a layer containing a wavelength conversion material or a layer containing a light diffusing material is disposed on the ±Z side surfaces of a molded body of resin, ceramic, glass, or the like.

[0027] The wavelength converting material contained in the wavelength converting member 14 is, for example, an yttrium-aluminum-garnet phosphor (e.g., (Y,Gd)3(Al,Ga)5O 12 :Ce), lutetium aluminum garnet phosphors (e.g., Lu3(Al,Ga)5O 12:(Ce), terbium-aluminum-garnet-based phosphor (e.g., Tb3(Al,Ga)5O 12 :(Ce), CCA-based phosphor (e.g., Ca 10 (PO4)6Cl2:Eu), SAE-based phosphor (e.g., Sr4Al 14 O 25 :Eu), chlorosilicate-based phosphor (e.g., Ca8MgSi4O 16 Cl2:Eu), silicate-based phosphor (e.g., (Ba,Sr,Ca,Mg)2SiO4:Eu), β-sialon-based phosphor (e.g., (Si,Al)3(O,N)4:Eu) or α-sialon-based phosphor (e.g., Ca(Si,Al) 12 (O,N) 16 :Eu) and other oxynitride-based phosphors, LSN-based phosphor (e.g., (La,Y)3Si6N 11 :Ce), BSESN-based phosphor (e.g., (Ba,Sr)2Si5N8:Eu), SLA-based phosphor (e.g., SrLiAl3N4:Eu), CASN-based phosphor (e.g., CaAlSiN3:Eu) or SCASN-based phosphor (e.g., (Sr,Ca)AlSiN3:Eu) and other nitride-based phosphors, KSF-based phosphor (e.g., K2SiF6:Mn), KSAF-based phosphor (e.g., K2(Si 1-x Al x )F 6-x :Mn where x satisfies 0 < x < 1.), or fluoride-based phosphors such as MGF-based phosphor (e.g., 3.5MgO·0.5MgF2·GeO2:Mn), quantum dots having a perovskite structure (e.g., (Cs,FA,MA)(Pb,Sn)(F,Cl,Br,I)3 where FA and MA represent formamidinium and methylammonium, respectively), II-VI group quantum dots (e.g., CdSe), III-V group quantum dots (e.g., InP), or quantum dots having a chalcopyrite structure (e.g., (Ag,Cu)(In,Ga)(S,Se)2) can be used. The wavelength conversion materials described above are particles. Also, one of these wavelength conversion materials can be used alone, or two or more of these wavelength conversion materials can be used in combination.

[0028] In this embodiment, the light source 1 uses a blue LED as the light emitting element 12, and the wavelength conversion member 14 contains a wavelength conversion material that converts the wavelength of the light emitted from the light emitting element 12 to yellow. This allows the light source 1 to emit white light. The wavelength or chromaticity of the light emitted from the light source 1 may be selected appropriately depending on the intended use of the light emitting module 100. The wavelength conversion member 14 may contain a light diffusing material. Examples of light diffusing materials that can be used include titanium oxide, barium titanate, aluminum oxide, and silicon oxide.

[0029] The light-shielding member 15 covers the side surfaces of the light-emitting element 12 and the wavelength conversion member 14. The light-shielding member 15 directly or indirectly covers the side surfaces of the light-emitting element 12 and the wavelength conversion member 14. The upper surface of the wavelength conversion member 14 in FIG. 3 is exposed from the light-shielding member 15 and constitutes the light-emitting surface 11 of the light source 1. The light-shielding member 15 is preferably made of a material with high light reflectivity in order to improve the light extraction efficiency of the light source 1. For example, a resin material containing a light-reflecting substance such as a white pigment can be used for the light-shielding member 15. Alternatively, the light-shielding member 15 may be a light-reflective member made of an inorganic material containing, for example, boron nitride or alkali metal silicate. In this case, the light-shielding member 15 may further contain titanium oxide or zirconium oxide.

[0030] Examples of light-reflecting materials include titanium oxide, zinc oxide, magnesium oxide, magnesium carbonate, magnesium hydroxide, calcium carbonate, calcium hydroxide, calcium silicate, magnesium silicate, barium titanate, barium sulfate, aluminum hydroxide, aluminum oxide, zirconium oxide, and silicon oxide. It is preferable to use one of these materials alone or two or more of these materials in combination. Furthermore, it is preferable to use a resin material whose main component is a thermosetting resin, such as an epoxy resin, an epoxy-modified resin, a silicone resin, a silicone-modified resin, or a phenolic resin. The light-shielding member 15 may contain a material that absorbs visible light, if necessary. Examples of light-absorbing materials include carbon black and titanium black.

[0031] (Board 2) The light source 1 is disposed on a substrate 2. The substrate 2 has wiring 21 on at least its surface. The light source 1 is electrically connected to the wiring 21 provided on the substrate 2. The substrate 2 may have wiring 21 inside. The light source 1 and the substrate 2 are electrically connected between the wiring 21 of the substrate 2 and the electrode 13 of the light emitting element 12 via a bonding member such as a conductive member 22. The configuration, size, etc. of the wiring 21 of the substrate 2 are set according to the configuration and size of the electrode 13 of the light emitting element 12.

[0032] 1, the substrate 2 is a plate-like member that is substantially rectangular when viewed from above. The shape of the substrate 2 when viewed from above may be substantially circular, elliptical, polygonal, or the like. Electronic components other than the light source 1 may also be arranged on the substrate 2. The electronic components may be Zener diodes, thermistors, capacitors, ambient light sensors, or the like.

[0033] The substrate 2 preferably uses an insulating material as its base material, and preferably uses a material that is less transmissive to light emitted from the light source 1, external light, etc. In this specification, external light is not limited to sunlight, but includes all light that enters the light emitting module 100 from the outside. The substrate 2 preferably uses a material that has a certain strength. Specifically, the substrate 2 can be formed using ceramics such as alumina, aluminum nitride, mullite, and silicon nitride, or resins such as phenolic resin, epoxy resin, polyimide resin, BT resin (bismaleimide triazine resin), polyphthalamide, and polyester resin as its base material.

[0034] The wiring 21 can be made of at least one of copper, iron, nickel, tungsten, chromium, aluminum, silver, gold, titanium, palladium, rhodium, alloys thereof, etc. Furthermore, a layer of silver, platinum, aluminum, rhodium, gold, alloys thereof, etc. may be provided on the surface of the wiring 21 from the viewpoint of at least one of the wettability and light reflectivity of the conductive member 22.

[0035] (Optical component 3) 1, the outer shape of the optical member 3 when viewed from above is substantially rectangular. The lens 31 is supported by a support portion 32 arranged outside the lens 31 when viewed from above. When viewed from above, a leg portion 33 continuing from the support portion 32 is arranged outside the support portion 32. The optical member 3 is bonded to the substrate 2 by an adhesive member 4 arranged between a lower surface 331 of the leg portion 33 and the upper surface 23 of the substrate 2. Note that in this embodiment, the outer shape of the optical member 3 when viewed from above may be substantially circular, substantially elliptical, substantially polygonal, or the like.

[0036] Portions of the optical member 3 other than the first magnet portion 330 are made of at least one of a resin material, such as polycarbonate resin, acrylic resin, silicone resin, or epoxy resin, or a glass material. The lens 31, support portion 32, and leg portion 33 are connected to one another as an integrated member. However, the support portion 32 and leg portion 33 may be separate members from the lens 31. Alternatively, the support portion 32 and leg portion 33 may each be a part of an integrated member made of the same material. In this case, in the optical member 3, the first magnet portion 330 is disposed on at least a part of the lower surface of the support portion 32. Note that the translucency of the optical member 3 refers to the property of being able to transmit 60% or more of the light from the light source 1.

[0037] The lens 31 is a Fresnel lens. However, the lens 31 is not limited to a Fresnel lens and may have other forms, such as a biconvex single lens, a plano-convex single lens, a biconcave single lens, a plano-concave single lens, a Fresnel lens, a lens assembly consisting of multiple lenses, an array lens, a meniscus single lens, an aspherical lens, or a cylindrical lens. The lens 31 is translucent to the light emitted by the light source 1. The lens 31 is made of at least one of a resin material such as polycarbonate resin, acrylic resin, silicone resin, or epoxy resin, or a glass material.

[0038] The outer shape of the lens 31 when viewed from above is substantially circular. However, the outer shape of the lens 31 when viewed from above may be substantially rectangular, substantially elliptical, substantially polygonal, or the like. The shape of the lens 31 when viewed from above is rotationally symmetric. Considering that the shooting range of a typical imaging device is substantially rectangular, the shape of the lens 31 when viewed from above may be a four-fold rotationally symmetric shape or a two-fold rotationally symmetric shape.

[0039] The support portion 32 is a frame-shaped portion provided on the outside of the lens 31 when viewed from above. The support portion 32 may be translucent or light-blocking to the light emitted by the light source 1. The shape of the inside of the support portion 32 when viewed from above (i.e., the interface between the lens 31 and the support portion 32 in the optical member 3) is approximately circular, similar to the outer shape of the lens 31. On the other hand, the shape of the outside of the support portion 32 when viewed from above is approximately rectangular. In the example shown in FIG. 2 , the support portion 32 is provided on the outside of the lens 31 so as to have a flat surface on the +Z side (hereinafter sometimes referred to as the upper side). The support portion 32 is not limited to a flat surface, and may have a convex surface, a concave surface, a rough surface, or the like.

[0040] The leg portion 33 is a rectangular frame-shaped portion provided on the outside of the support portion 32 in a top view. The leg portion 33 may be translucent or light-blocking to the light emitted by the light source 1. In a top view, the leg portion 33 has a substantially rectangular shape on both the inside and outside. The leg portion 33 has a shape that is long on the -Z side so as to extend to the -Z side (hereinafter sometimes referred to as downward) outside the lens 31. The leg portion 33 supports the lens 31 and the support portion 32 so that the lens 31 is disposed above the light source 1 and the support portion 32 is disposed outside the lens 31 in a top view.

[0041] The first magnet portion 330 constitutes the lower portion of the leg portion 33. The first magnet portion 330 has a rectangular frame shape when viewed from above. In the light-emitting module 100 shown in FIG. 1, the first magnet portion 330 has a continuous rectangular frame shape and is provided on the lower portion of the leg portion 33 when viewed from above. However, the first magnet portion 330 may be provided on at least a part of the lower surface 331 of the leg portion 33. For example, the optical member 3 may include a plurality of first magnet portions 330, and the plurality of first magnet portions 330 may be provided at each of the four corners of the rectangular frame-shaped leg portion 33 when viewed from above.

[0042] The magnetic material contained in the first magnet section 330 may be a ferrite-based magnetic material or a rare earth-based magnetic material. Among them, it is preferable to use a rare earth-based magnetic material with high magnetic force in order to perform alignment efficiently. Examples of rare earth-based magnetic materials include neodymium iron boron (NdFeB), samarium cobalt (SmCo), and samarium iron nitrogen (SmFeN). For example, the magnetic material of the first magnet section 330 is samarium iron nitrogen. Samarium iron nitrogen contains 25% samarium (Sm2) as a rare earth metal and 25% iron (Fe) as a transition metal. 17 ) and 3% nitrogen (N). The particle shape of the magnetic material contained in the first magnet section 330 may be a regular shape such as a sphere or a plate, or may be irregular. In particular, it is preferable that the particle shape of the magnetic material is spherical. This allows more particles to be contained in the first magnet section 330, making the first magnet section a magnet section with stronger magnetic force. The particle diameter of the magnetic material is preferably an average particle diameter of approximately 1 μm to 10 μm, and more preferably approximately 2 μm to 5 μm.

[0043] The resin material contained in the first magnet portion 330 functions as a binder for the magnetic material. Known resins such as thermosetting resins and thermoplastic resins can be used as the resin material. Specifically, thermoplastic resins such as polyphenylene sulfide (PPS), polypropylene (PP), and polyamide (PA) can be preferably used.

[0044] Since the first magnet portion 330 contains a magnetic material and a resin material, the first magnet portion 330 can be formed by injection molding. By using injection molding, the optical member 3 containing a magnetic material can be easily processed into a desired shape, similar to processing a resin material. The magnetic material and resin material contained in the first magnet portion 330 can be changed as appropriate depending on the specifications of the light-emitting module 100, etc.

[0045] (Adhesive material 4) The adhesive member 4 is a member that bonds the optical member 3 and the substrate 2. For example, a resin material such as a thermosetting resin, a thermoplastic resin, or an ultraviolet curable resin can be suitably used as the adhesive member 4. Specific examples include acrylic resin, polycarbonate resin, epoxy resin, modified epoxy resin, silicone resin, modified silicone resin, and hybrid silicone resin.

[0046] <Method of manufacturing the light emitting module 100> A method for manufacturing a light emitting module according to this embodiment will be described with reference to Fig. 4 to Fig. 12.

Note that Figs. 6 to 8 each show a cross section corresponding to line II-II in Fig. 1.

[0048] Fig. 9 is a schematic top view showing the step of arranging the optical member 3 in the manufacturing method of the light-emitting module according to this embodiment. Fig. 10 is a schematic cross-sectional view taken along the line XX in Fig. 9. Fig. 11 is a schematic cross-sectional view showing a state in which the lens 31 is misaligned with respect to the light source 1 in the step of arranging the optical member 3 in the manufacturing method of the light-emitting module according to this embodiment. Fig. 12 is a schematic cross-sectional view showing a state in which the lens 31 is positioned with respect to the light source 1 in the step of arranging the optical member 3 in the manufacturing method of the light-emitting module according to this embodiment. Note that Figs. 11 and 12 each show a cross section corresponding to the line XX in Fig. 9.

[0049] 4, the method for manufacturing the light-emitting module 100 according to this embodiment includes the steps of: preparing the substrate 2 (S11); preparing the optical member 3 (S12); and arranging the lower surfaces 331 of the legs 33 of the optical member 3 on the upper surface 23 of the substrate 2 so that the lenses 31 face the light source 1 (S14). In the example shown in FIG. 4, the method for manufacturing the light-emitting module 100 also includes the steps of arranging the uncured adhesive member 4 on the upper surface 23 of the substrate 2 (S13); and curing the adhesive member 4 while the optical member 3 is positioned relative to the light source 1 by the second magnet portion 6 (S15).

[0050] (S11: Step of preparing substrate 2) In the step (S11) of preparing the substrate 2, the light source 1 and the substrate 2 on which the light source 1 is arranged on the upper surface 23 are prepared. In this embodiment, preparing the substrate 2 includes obtaining the light source 1 and the substrate 2 by manufacturing or purchasing them and arranging the light source on the substrate 2, and purchasing the substrate 2 on which the light source 1 is arranged. In the example shown in FIG. 4 , the step of preparing the substrate 2 includes a step of preparing an aggregate substrate 20 on which a plurality of light sources 1 are arranged on the upper surface 201, and a step of singulating the light sources 1.

[0051] As shown in FIG. 5, light sources 1-1 and 1-2 are arranged on an upper surface 201 of the aggregate substrate 20. However, the number of light sources 1 arranged on the upper surface 201 of the aggregate substrate 20 is not limited to two and may be three or more. By separating the aggregate substrate 20 into individual substrates, a substrate 2 is obtained, with one light source 1 arranged on an upper surface 23, as shown in FIG. 6. By singulating the aggregate substrate 20, a plurality of substrates 2 can be obtained from the aggregate substrate 20. The aggregate substrate 20 can be singulated by laser processing or blade processing.

[0052] (S12: Step of preparing optical member 3) 7, in the step (S12) of preparing the optical member 3, an optical member 3 is prepared that includes a lens 31, a support portion 32 that supports the lens 31, and legs 33 that are arranged outside the support portion 32 in a top view. Note that in this embodiment, preparing the optical member 3 is not limited to preparing the optical member 3 by manufacturing, but also includes preparing the optical member 3 by purchasing it.

[0053] For example, the step of preparing the optical member 3 includes a step of manufacturing the optical member 3 by two-color molding. The two-color molding method for the optical member 3 is a processing method in which the lens 31, the support portion 32, and the portions of the leg portion 33 other than the first magnet portion 330 are molded using different materials from the first magnet portion 330. Specifically, in the two-color molding method for the optical member 3, the lens 31, the support portion 32, and the portions of the leg portion 33 other than the first magnet portion 330 are molded using a translucent resin material, and the first magnet portion 330 is molded using a magnetic material and a binder resin material. By using the two-color molding method, the manufacturing efficiency of the optical member 3 can be improved.

[0054] The step of preparing the optical member 3 may also include a step of manufacturing the optical member 3 by a three-color molding process. The three-color molding process for the optical member 3 is a process in which the lens 31, the support portion 32 and the leg portion 33 portions other than the first magnet portion 330, and the first magnet portion 330 are molded using different materials. Specifically, in the three-color molding process for the optical member 3, the lens 31 is molded using a translucent resin material, the support portion 32 and the leg portion 33 portions other than the first magnet portion 330 are molded using a light-blocking resin material, and the first magnet portion 330 is molded using a magnetic material and a binder resin material. Then, the lens 31, the support portion 32 and the leg portion 33 portions other than the first magnet portion 330, and the first magnet portion 330 are integrated together. The three-color molding process can improve the manufacturing efficiency of the optical member 3.

[0055] The process of preparing the optical member 3 includes a process of preparing the first magnet portion 330, in which a magnetic material and a resin material are mixed and molded, and then the molded product is magnetized to form the first magnet portion 330. By applying a strong magnetic field to the molded product, the first magnet portion 330 having a strong magnetic force is obtained. The first magnet portion 330 is magnetized so that the magnetic alignment is such that different polarities are arranged on the upper and lower sides (i.e., the leg portion 33 side and the substrate 2 side). This allows for more accurate alignment in the process of placing the optical member 3, which will be described later. The process of preparing the optical member 3 may be performed before the process of preparing the substrate 2.

[0056] (S13: Step of placing uncured adhesive member 4) As shown in FIG. 8, in the step (S13) of arranging the uncured adhesive member 4, the uncured adhesive member 4 is arranged on the upper surface 23 of the substrate 2. An adhesive member containing a resin such as an ultraviolet-curable or thermosetting resin can be used as the adhesive member 4. The uncured adhesive member 4 is arranged on the upper surface 23 of the substrate 2 in a portion where the optical member 3 is to be arranged, using a dispenser or the like. In the example shown in FIG. 8, the uncured adhesive member 4 is arranged continuously in a rectangular frame shape on the upper surface 23 of the substrate 2 in line with the legs 33 when viewed from above. However, the uncured adhesive member 4 is not limited to being arranged continuously, and may be arranged intermittently at positions corresponding to the four corners of the rectangular frame-shaped legs 33.

[0057] (S14: Step of placing optical member 3) In the step (S14) of arranging the optical member 3, the lower surfaces 331 of the legs 33 of the optical member 3 are arranged on the upper surface 23 of the substrate 2 so that the lens 31 faces the light source 1. In this step, the second magnet portion 6, which is arranged on the opposite side of the substrate 2 from the optical member 3, attracts the first magnet portion 330 by magnetic force, thereby positioning the lens 31 with respect to the light source 1. FIGS. 9 and 10 show an example of arranging the optical member 3 so that the lens 31 faces the light source 1 using the jig plate 5 and the second magnet portion 6.

[0058] The fixture plate 5 is a plate-like member used to position the light source 1 and the lens 31. The fixture plate 5 is made of a resin material or the like and is not magnetic. The fixture plate 5 includes an upper surface 51 on which the substrate 2 is placed and a lower surface 52 located on the opposite side of the upper surface 51.

[0059] The second magnet section 6 is a member that functions as a magnet. The second magnet section 6 includes, for example, a permanent magnet. However, the second magnet section 6 may also include a temporary magnet such as an electromagnet. The second magnet section 6 is placed on the jig plate 5 so as to have a predetermined positional relationship with the light source 1.

[0060] In the example shown in FIGS. 9 and 10 , the second magnet portion 6 is disposed at a predetermined position on the lower surface 52 of the fixture plate 5 on the opposite side of the optical member 3 relative to the substrate 2. Here, multiple second magnet portions 6 are disposed at positions corresponding to the four corners 333 of the rectangular frame-shaped leg portion 33 when viewed from above. The first magnet portion 330 and the second magnet portion 6 attract each other by magnetic force, allowing the optical member 3 to be positioned at a position corresponding to the predetermined position of the second magnet portion 6 on the upper surface 23 of the substrate 2. The second magnet portion 6 is disposed so that the polarity opposite to the polarity of the lower surface of the first magnet portion 330, which is to be aligned, is located on the upper side (i.e., the side facing the lower surface of the first magnet portion 330). This allows the lens 31 of the optical member 3 to be positioned relative to the light source 1 disposed on the substrate 2.

[0061] For example, as shown in Figure 11, suppose the optical member 3 is placed on the substrate 2 with the optical axis 31C offset in the first direction X by an offset amount d from the light source axis 1C. In this case, the second magnet axis 6C is offset in the first direction X by an offset amount d from the first magnet axis 330C located near the second magnet portion 6. The first magnet axis 330C is an axis that passes through the center of the first magnet portion 330 in a top view and extends in a direction along the optical axis 31C. The second magnet axis 6C is an axis that passes through the center of the second magnet portion 6 in a top view and extends in a direction along the optical axis 31C.

[0062] In the above case, in the manufacturing method of the light-emitting module according to this embodiment, the second magnet portion 6 attracts the first magnet portion 330 located near the second magnet portion 6 so that the second magnet axis 6C and the first magnet axis 330C approach each other. As a result, as shown in FIG. 12 , the optical member 3 moves in the movement direction m, and the lens 31 moves in the movement direction m. When the second magnet axis 6C and the first magnet axis 330C are substantially aligned with each other due to the movement of the optical member 3 and the lens 31, the light source axis 1C of the light source 1, which is in a predetermined positional relationship with the second magnet portion 6, and the optical axis 31C of the lens 31, which is in a predetermined positional relationship with the first magnet portion 330, are substantially aligned with each other. As a result, the lens 31 is positioned relative to the light source 1. As described above, in the manufacturing method of the light-emitting module according to this embodiment, the optical member 3 autonomously moves so that the light source axis 1C and the optical axis 31C are substantially aligned with each other, and the lens 31 can be positioned relative to the light source 1, and the optical member 3 can be disposed on the upper surface 23 of the substrate 2.

[0063] (S15: Step of curing adhesive member 4) In S15, the adhesive member 4 is hardened with the lens 31 positioned relative to the light source 1 by the second magnet portion 6. If the adhesive member 4 is an ultraviolet-curing adhesive member, the adhesive member 4 can be hardened by irradiating it with ultraviolet light with the lens 31 positioned relative to the light source 1. If the adhesive member 4 is a thermosetting adhesive member, the adhesive member 4 can be hardened by heating it with the lens 31 positioned relative to the light source 1. The optical member 3 is adhered to the substrate 2 by hardening the adhesive member 4. The light-emitting module 100 can be manufactured by adhering the optical member 3 to the substrate 2.

[0064] In this embodiment, by using the first magnet portion 330 and the second magnet portion 6, the lens 31 can be positioned relative to the light source 1 without performing image recognition processing and positioning control. This reduces the time required for positioning and increases the manufacturing efficiency of the light-emitting module.

[0065] In this embodiment, the uncured adhesive member 4 is placed in S13, and then the lens 31 is positioned relative to the light source 1 in S14, and then the adhesive member 4 is cured in S15. This allows the lens 31 to be positioned relative to the light source 1 and the optical member 3 to be fixed to the substrate 2.

[0066] In this embodiment, a plurality of optical members 3 can be fixed to a plurality of substrates 2 at the same time. Fig. 13 is a schematic perspective view showing a step of fixing a plurality of optical members 3 to a plurality of substrates 2 at the same time in the method for manufacturing a light-emitting module according to this embodiment.

[0067] 13 , 30 substrates 2, each having one light source 1 disposed thereon, are placed on an upper surface 51 of a jig plate 5. Second magnet portions are arranged on a lower surface 52 of the jig plate 5, corresponding to the optical members 3 disposed on each of the 30 substrates 2. For example, four second magnet portions are arranged on the lower surface 52 of the jig plate 5, corresponding to the four corners of the leg portion 33, which has a rectangular frame shape when viewed from above, for each substrate 2. The four second magnet portions arranged on one substrate are arranged on the lower surface 52 of the jig plate 5 so as to have a predetermined positional relationship with the light sources 1 disposed on the substrate 2.

[0068] 13 , an uncured adhesive member 4 is placed on the upper surface 23 of each of the 30 substrates 2. Then, 30 optical members 3 are placed on the upper surfaces 23 of the corresponding 30 substrates 2. The second magnet portion 6 placed on the lower surface 52 of the jig plate 5 and the first magnet portion 330 of each of the 30 optical members 3 are attracted to each other, thereby positioning the lenses 31 of each of the 30 optical members 3 with respect to the corresponding light source 1.

[0069] After the lenses 31 of the 30 optical members 3 have all been positioned relative to the corresponding light sources 1, the adhesive members 4 are cured by, for example, irradiating the adhesive members 4 with ultraviolet light or heating the adhesive members 4. As the adhesive members 4 are cured, the 30 optical members 3 are adhered to the corresponding 30 substrates 2. In this way, the adhesive members 4 are cured collectively while the optical members 3 are fixed to the corresponding substrates 2 by magnetic force, thereby manufacturing a plurality of light-emitting modules. Furthermore, as the adhesive members 4 are cured collectively, the manufacturing efficiency of the light-emitting modules can be further improved.

[0070] When magnets are not used for fixation, for example, each of the 30 optical members 3 can be positioned relative to a corresponding light source 1 using image recognition processing or the like, and the adhesive member 4 can be cured to bond the lenses 31 to the desired positions on the substrate 2. Alternatively, each of the 30 optical members 3 can be positioned relative to a corresponding light source 1 using image recognition processing or the like, and the adhesive member 4 can be pre-cured to fix the optical members 3. The pre-cured optical members 3 and the corresponding substrates 2 can then be subjected to a full curing process for the adhesive member 4 all at once. Here, pre-curing refers to a state in which the adhesive member is not completely cured but its shape is stable. For example, this refers to a state in which the optical members 3 are not completely fixed to the substrate 2, and the adhesive member 4 is cured in a state in which the optical members 3 can be moved on the substrate 2 by a person pressing the optical members 3. In the manufacturing method according to this embodiment, the optical members 3 are positioned and fixed at the positioned positions using magnetic force, eliminating the need for individual curing processes and pre-curing processes for each positioning step.

[0071] [Second embodiment] Next, a light-emitting module according to a second embodiment will be described. Note that the same names and symbols as those in the previously described embodiments indicate the same or similar components or configurations, and detailed descriptions will be omitted as appropriate. This also applies to the following embodiments and modified examples.

[0072] Fig. 14 is a schematic top view of a light emitting module 100a according to the second embodiment, and Fig. 15 is a schematic cross-sectional view taken along line XV-XV in Fig. 14.

[0073] The light-emitting module 100a of this embodiment differs from the light-emitting module 100 of the first embodiment in that the leg portion 33a of the optical element 3 includes a first magnet portion 330a extending from the lower surface 331 of the leg portion 33a to the upper surface 332 of the leg portion 33a.

[0074] In the optical member 3, the first magnet portion 330a is exposed from the upper surface 332 of the leg portion 33a. As a result, for example, when a magnetic member is placed on the upper surface 332 of the leg portion 33a, the magnetic force of the first magnet portion 330a acts on the member, making it possible to move the member according to the position of the first magnet portion 330a. The magnetic member placed on the upper surface 332 of the leg portion 33a is, for example, a translucent member having a lens and including a magnet portion on at least a portion of its lower surface facing the upper surface 332 of the leg portion 33a, as in the optical member shown in FIG. 7. Desired optical characteristics can be obtained by combining the lens 31 of the optical member 3 with the lens of the translucent member.

[0075] In this embodiment, when a magnetic member is placed on the upper surface 332 of the leg portion 33a, the member can be moved by the magnetic force of the first magnet portion 330a, thereby improving the efficiency of positioning the member and the optical member 3 with respect to the light source 1. As a result, in this embodiment, it is possible to provide a light-emitting module 100a that can be manufactured with high efficiency.

[0076] The light emitting module 100a can be manufactured by the same method as that of the light emitting module 100 according to the first embodiment. Furthermore, the light emitting module 100a has the same effects as those of the light emitting module 100 according to the first embodiment, except for those mentioned above.

[0077] [Third embodiment] Next, a light emitting module according to a third embodiment will be described. Fig. 16 is a schematic top view of a light emitting module 100b according to the third embodiment. Fig. 17 is a schematic cross-sectional view taken along line XVII-XVII in Fig. 16.

[0078] In the light-emitting module 100b according to this embodiment, the support portion 32b and the leg portion 33b of the optical member 3 include a magnetic material, and the leg portion 33b of the optical member 3 includes a first magnet portion 330b extending from a lower surface 331 of the leg portion 33b to an upper surface 332 of the leg portion 33b, and a magnetic material. In addition, the substrate 2 includes a second magnet portion 6b. The above points are different from the light-emitting module 100 according to the first embodiment.

[0079] In the light-emitting module 100b according to this embodiment, the support portion 32b and the leg portion 33b other than the lens 31 in the optical member 3 can be formed by molding a mixture of a magnetic material and a resin material. The first magnet portion 330b is a magnetized portion of the leg portion 33b (here, a portion extending from the lower surface 331 to the upper surface 332 of the leg portion 33b) which is made up of a magnetic material.

[0080] The first magnet portion 330b is exposed from the upper surface 332 of the leg portion 33b. As a result, for example, when a magnetic member is placed on the upper surface 332 of the leg portion 33b, the magnetic force of the first magnet portion 330b acts on the member, making it possible to move the member according to the position of the first magnet portion 330b. The magnetic member placed on the upper surface 332 of the leg portion 33b is, for example, a translucent member having a lens and including a magnet portion on at least a portion of its underside facing the upper surface 332 of the leg portion 33b. Desired optical characteristics can be obtained by combining the lens 31 of the optical member 3 with a lens of a translucent member.

[0081] The second magnet portion 6b is a member that functions as a magnet. The second magnet portion 6b includes, for example, a permanent magnet. However, the second magnet portion 6b may also include a temporary magnet such as an electromagnet. The second magnet portion 6b shown in FIGS. 16 and 17 is disposed and fixed at a predetermined position inside the substrate 2 so as to have a predetermined positional relationship with the light source 1. In the example shown in FIGS. 16 and 17, the second magnet portion 6b is disposed at positions corresponding to the four corners 333 of the rectangular frame-shaped leg portion 33b when viewed from above.

[0082] The magnetic force of the first magnet portion 330b and the second magnet portion 6b places the optical member 3 at a position on the upper surface 23 of the substrate 2 that corresponds to a predetermined position of the second magnet portion 6b. This positions the lens 31 of the optical member 3 relative to the light source 1. For example, even if the optical member 3 is placed on the substrate 2 with the lens 31 misaligned relative to the light source 1, the second magnet portion 6b attracts the first magnet portion 330b of the optical member 3, thereby positioning the lens 31 relative to the light source 1.

[0083] In this embodiment, in the process of preparing the optical member 3, the first magnet portion 330b, the support portion 32, and the leg portion 33, which are portions other than the lens 31, can be molded collectively using a magnetic material and a resin material. This allows the leg portion 33 and the first magnet portion 330b to be aligned with greater precision.

[0084] In addition, in this embodiment, by partially magnetizing a portion of the leg portion 33b, which is made of a magnetic material, to provide the first magnet portion 330b, the freedom of selection of the position or size of the first magnet portion 330b can be increased.

[0085] Furthermore, in this embodiment, since the second magnet portion 6b is disposed on the substrate 2, the lens 31 can be positioned relative to the light source 1 without using the jig plate 5 in the first embodiment and the second magnet portion 6 disposed on the lower surface 52 of the jig plate 5. This facilitates the manufacture of the light-emitting module 100b. Note that the second magnet portion 6b is not limited to being located inside the substrate 2, and may be fixed to either the upper surface 23 or the lower surface 24 of the substrate 2.

[0086] [Variations] The configuration and arrangement of the first magnet portion and the second magnet portion can be modified in various ways. Modified examples of the first magnet portion and the second magnet portion will be described below. Note that the following modifications show modifications of the first magnet portion of the light-emitting module 100 according to the first embodiment, but similar modifications are also possible for the first magnet portion 330a of the light-emitting module 100a according to the second embodiment and the first magnet portion 330b of the light-emitting module 100b according to the third embodiment. Furthermore, while modifications of the second magnet portion 6 used in the manufacturing method for the light-emitting module according to the first embodiment are shown, similar modifications are also possible for the second magnet portion 6a used in the manufacturing method for the light-emitting module according to the second embodiment and the second magnet portion 6b used in the manufacturing method for the light-emitting module according to the third embodiment.

[0087] (First Modification) Fig. 18 is a schematic top view of a light-emitting module 100c according to Modification 1. Fig. 19 is a schematic top view showing a jig plate 5 and a second magnet portion 6c used in the method for manufacturing a light-emitting module according to Modification 1.

[0088] In light-emitting module 100c according to this modification, first magnet portion 330c includes, on its lower surface (i.e., the side facing substrate 2), at least one first magnetized portion 330S and at least one second magnetized portion 330N magnetized to the opposite magnetic polarity to first magnetized portion 330S. Second magnet portion 6c includes, on its upper surface (i.e., the side facing first magnet portion 330c), at least one third magnetized portion 6N magnetized to the opposite magnetic polarity to first magnetized portion 330S and at least one fourth magnetized portion 6S magnetized to the opposite magnetic polarity to third magnetized portion 6N. In other words, light-emitting module 100c differs from light-emitting module 100 according to the first embodiment in that light-emitting module 100c includes first magnet portion 330c and second magnet portion 6c whose at least one surface (the surfaces facing each other) is magnetized to multiple poles.

[0089] In the example shown in FIG. 18 , the at least one first magnetized portion 330S is one first magnetized portion 330S. The first magnetized portion 330S is a portion magnetized to the south pole. The at least one second magnetized portion 330N is one second magnetized portion 330N. The second magnetized portion 330N is a portion magnetized to the north pole. In a top view, the first magnetized portion 330S and the second magnetized portion 330N have shapes that are approximately mirror-symmetrical with respect to a module mirror axis N1 that intersects the optical axis 31C and extends in the second direction Y. The first magnetized portion 330S and the second magnetized portion 330N are arranged on the optical member 3 so as to have a predetermined positional relationship with the lens 31.

[0090] In the example shown in FIG. 19 , the at least one third magnetized portion 6N is one third magnetized portion 6N. The third magnetized portion 6N is a portion magnetized to the north pole. The at least one fourth magnetized portion 6S is one fourth magnetized portion 6S. The fourth magnetized portion 6S is a portion magnetized to the south pole. In a top view, the third magnetized portion 6N and the fourth magnetized portion 6S have shapes that are approximately mirror-symmetrical with respect to the jig plate mirror axis N2 that passes through the center 5C of the jig plate 5 and extends in the second direction Y. The third magnetized portion 6N and the fourth magnetized portion 6S are arranged on the jig plate 5 so as to have a predetermined positional relationship with the light source 1.

[0091] The first magnetized portion 330S and the third magnetized portion 6N have opposite magnetic poles and therefore attract each other. The second magnetized portion 330N and the fourth magnetized portion 6S also have opposite magnetic poles and therefore attract each other. Therefore, in the process of arranging the lower surfaces 331 of the leg portions 33 of the optical member 3 on the upper surface 23 of the substrate 2 so that the lens 31 faces the light source 1, when the lower surfaces 331 of the leg portions 33 of the optical member 3 are arranged on the upper surface 23 of the substrate 2, the third magnetized portion 6N attracts the first magnetized portion 330S. The fourth magnetized portion 6S attracts the second magnetized portion 330N. As a result, in a top view, the first magnetized portion 330S and the third magnetized portion 6N overlap in a corresponding relationship, and the second magnetized portion 330N and the fourth magnetized portion 6S also overlap in a corresponding relationship. As a result, the lens 31 is positioned relative to the light source 1.

[0092] In this modification, the first magnet portion 330c includes the first magnetized portion 330S and the second magnetized portion 330N, and the second magnet portion 6c includes the third magnetized portion 6N and the fourth magnetized portion 6S, thereby improving positional accuracy.
