DETAILED DESCRIPTION

[0032] The light-emitting module of the embodiment of the present invention is described in detail with reference to the accompanying drawings.

In addition, the size, material, shape, relative configuration, etc. of the components described in the embodiments are not intended to limit the scope of the present invention to only these unless there is a specific description, but are merely illustrative examples. Note that the size, positional relationship, etc. of the components shown in the various figures are sometimes exaggerated for the sake of clarity. In addition, in the following description, for components that have the same name or figure mark indicating the same or homogeneous properties, detailed descriptions are appropriately omitted. As a cross-sectional view, an end view that only shows a cross section is sometimes used.

[0033] In the drawings shown below, directions are sometimes indicated by the X-axis, Y-axis, and Z-axis. The X-axis, Y-axis, and Z-axis are orthogonal to each other. The X direction along the X-axis and the Y direction along the Y-axis indicate directions along the light-emitting surface of the light-emitting unit of the light-emitting module of the embodiment. The Z direction along the Z-axis indicates a direction orthogonal to the light-emitting surface. That is, 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.

In the embodiment, as an example, each of the first light source and the second light source possessed by the light emitting module emits light to the +Z side. In the terminology of the embodiment, looking down refers to observing an object from above. As an example, the term looking down in the embodiment refers to observing an object from the upper surface side of the first lens possessed by the light emitting module of the embodiment. However, these are not limitations on the orientation of the light emitting module of the embodiment when in use, and the orientation of the light emitting module according to the embodiment is arbitrary. Note that in this specification, in addition to the portion that can be directly observed from above, the portion that cannot be directly observed from above can also be described using the term looking down, sometimes in a way that makes them appear to be visible through.

[0035] In addition, in this specification, the surface of the object when viewed from the +Z side is referred to as the "upper surface", and the surface of the object when viewed from the -Z side is referred to as the "lower surface".

In this embodiment, parallelism may include an error within ±10° relative to 0°. In addition, in this embodiment, orthogonality may include an error within ±10° relative to 90°.

[0036] [Example]

[0037] <Configuration example of the light emitting module of the embodiment>

[0038] (Overall structure)

[0039] Reference Figures 1 to 4 The overall structure of the light emitting module according to the embodiment will be described. Figure 1 1 is a schematic plan view showing an example of the light emitting module 100 according to the embodiment. Figure 2 yes Figure 1 Schematic cross-sectional view along line II-II in FIG. Figure 3 1 is a schematic top view showing the first light source 1 and the second light source 2 included in the light emitting module 100. Note that Figure 31 and 2 show a state where the first lens 3 , the second lens 4 , and the light-transmitting member 5 are removed from the light-emitting module 100 . Figure 4 1 is a schematic diagram showing light L1 irradiated onto the irradiation surface S from the first light emitting section 10 - 1 of the light emitting module 100 and light L2 irradiated onto the irradiation surface S from the third light emitting section 20 .

[0040] like Figures 1 to 4 As shown, the light emitting module 100 includes a first light source 1 and a second light source 2 which is arranged separately from the first light source 1 when viewed from above. Note that the horizontal direction is the direction along the light emitting surface 11 of the light emitting portion 10 of the first light source 1. Figures 1 to 4 In the example shown, it is the direction along the XY plane. The first light source 1 includes: a plurality of light emitting sections 10, including a first light emitting section 10-1 and a plurality of second light emitting sections 10-2 to 10-9 arranged around the first light emitting section 10-1; and a light shielding member 15, which is arranged between the plurality of light emitting sections 10 and exposes the light emitting surface 11 of each of the plurality of light emitting sections 10. The second light source 2 includes a third light emitting section 20 connected in parallel with the first light emitting section 10-1. On the irradiation surface S, the light L1 from the first light emitting section 10-1 and the light L2 from the third light emitting section 20 at least partially overlap.

[0041] exist Figure 4 In the example shown, the first irradiation area Ar1 represents an area of ​​the irradiation surface S irradiated by the light L1 from the first light emitting unit 10-1. The second irradiation area Ar2 represents an area of ​​the irradiation surface S irradiated by the light L2 from the third light emitting unit 20. The third irradiation area Ar3 represents an area of ​​the irradiation surface S where the light L1 and the light L2 overlap. In the third irradiation area Ar3, the light L1 and the light L2 overlap, so that the light amount increases. As a result, bright irradiation light is obtained in the third irradiation area Ar3.

[0042] As an example, the light emitting module 100 is a flash light emitting module mounted on a smartphone and provided in an imaging device of the smartphone. The imaging device includes a camera for capturing still images, a video camera for capturing moving images, and the like.

[0043] exist Figures 1 to 4 In the example shown, the first light source 1 includes nine light-emitting units 10 arranged in a 3×3 array. The first light-emitting unit 10-1 is arranged in the center. The second light-emitting units 10-2 to 10-9 are arranged around the first light-emitting unit 10-1. In the light-emitting module 100, the light-emitting unit 10 to be emitted can be selected from the nine light-emitting units 10 included in the first light source 1 by a camera device mounted on a smartphone, for example, according to a photography mode such as telephoto photography or wide-angle photography. In the light-emitting module 100, the light-emitting unit 10 to be emitted is selected, and light is irradiated through the lens by the selected light-emitting unit 10, so that the irradiation light corresponding to each irradiation mode can be irradiated.

[0044] For example, in telephoto photography, the light emitting module 100 can set the illumination mode to telephoto illumination by only making the first light emitting unit 10-1 emit light and not making the second light emitting units 10-2 to 10-9 emit light. By telephoto illumination, the light distribution angle of the illumination light becomes narrower, and the light can reach far away. The camera device can use the illumination light of the telephoto illumination for telephoto photography.

[0045] In addition, in wide-angle photography, the light-emitting module 100 causes the second light-emitting unit 10-3, the second light-emitting unit 10-8, the second light-emitting unit 10-5, and the second light-emitting unit 10-6, which are respectively adjacent to the first light-emitting unit 10-1 in the longitudinal and transverse directions, to emit light with a first light quantity. Furthermore, the second light-emitting unit 10-2, the second light-emitting unit 10-4, the second light-emitting unit 10-7, and the second light-emitting unit 10-9, which are adjacent to the first light-emitting unit 10-1 in the diagonal direction, emit light with a second light quantity greater than the first light quantity. Furthermore, the first light-emitting unit 10-1 emits light with a third light quantity less than the first light quantity. Thus, the light-emitting module 100 can set the illumination mode to wide-angle illumination. Through wide-angle illumination, the distribution angle of the illumination light is wider than the distribution angle of telephoto photography, and the light can be irradiated to a wide range. The camera device can use the illumination light of the wide-angle illumination for wide-angle photography.

[0046] Here, for example, in telephoto illumination, as described above, since only the first light-emitting section 10-1 needs to irradiate light having a prescribed light amount, the current input to the first light-emitting section 10-1 may increase. On the other hand, if the current input to the first light-emitting section 10-1 is increased in order to increase the amount of light, the junction temperature Tj of the light-emitting element provided in the first light-emitting section 10-1 may exceed the allowable value. Specifically, in the light-emitting module in which a prescribed current E (for example, a current of 2.5 A) is input to the first light-emitting section 10-1, if a current greater than the prescribed current E (for example, a current of 3.0 A) is input in order to increase the amount of light, the junction temperature Tj of the light-emitting element rises and may exceed the allowable value of the junction temperature Tj. Furthermore, if the input current is shunted to the second light emitting sections 10-2 to 10-9 located around the first light emitting section 10-1 in order to reduce the junction temperature Tj of the light emitting element included in the first light emitting section, for example, the light from the second light emitting sections 10-2 to 10-9 cannot reach far away because the light distribution angles of the light from the second light emitting sections 10-2 to 10-9 are wider than the light distribution angles of the light from the first light emitting section 10-1. As a result, the amount of light used for telephoto irradiation is reduced, and the quality of telephoto photography of the imaging device may be reduced.

[0047] In the light emitting module 100, by connecting the first light emitting part 10-1 of the first light source 1 and the third light emitting part 20 of the second light source 2 in parallel, the current supplied to the light emitting module 100 when emitting light is divided into the first light emitting part 10-1 and the third light emitting part 20. By dividing the supply current, the first light emitting part 10-1 and the third light emitting part 20 can emit light in parallel. The light L1 from the first light emitting part 10-1 and the light L2 from the third light emitting part 20 overlap at least partially on the irradiation surface S. By overlapping the light L1 and the light L2 in the irradiation surface S, the light amount of the light L1 can be supplemented by the light amount of the light L2, so that the light amount of the telescopic irradiation in the irradiation surface S is increased and brightened. Therefore, in the present embodiment, a light emitting module 100 can be provided, which can irradiate light that can obtain the desired light amount characteristics in the irradiation surface S, thereby irradiating light with the desired characteristics.

[0048] Furthermore, in the light emitting module 100, by dividing the current input to the light emitting module 100 into the first light emitting portion 10-1 and the third light emitting portion 20, the temperature rise of the first light emitting portion 10-1 caused by the current being concentrated in the first light emitting portion 10-1 can be reduced. Furthermore, in the light emitting module 100, the second light source 2 including the third light emitting portion 20 is arranged separately from the first light source 1 including the first light emitting portion 10-1. Therefore, compared with the case where the third light emitting portion 20 is arranged close to the first light emitting portion 10-1, the heat dissipation is improved, and thus the temperature rise of the first light emitting portion 10-1 can be reduced. By reducing the temperature rise of the first light emitting portion 10-1, the situation where the temperature of the light emitting element provided in the first light emitting portion 10-1 exceeds the allowable value of the junction temperature Tj when emitting light can be reduced, and the failure or damage of the light emitting module 100 can be reduced. Therefore, in the present embodiment, a light emitting module 100 with high reliability can be provided.

[0049] In other forms of the light emitting module 100, the first light emitting unit 10-1 of the first light source 1 and the third light emitting unit 20 of the second light source 2 do not necessarily need to be connected in parallel, as long as the light L1 from the first light emitting unit 10-1 and the light L2 from the third light emitting unit 20 at least partially overlap on the irradiation surface S. For example, the light emitting module 100 includes: a first light source 1 including a first light emitting unit 10-1 and second light emitting units 10-2 to 10-9 arranged around the first light emitting unit 10-1; and a second light source 2, which is arranged separately from the first light source 1 in a plan view and includes the third light emitting unit 20. On the irradiation surface S, the light L1 from the first light emitting unit 10-1 and the light L2 from the third light emitting unit 20 at least partially overlap. The light-emitting module 100 can switch between a first illumination mode and a second illumination mode, wherein in the first illumination mode, only the first light-emitting unit 10-1 and the third light-emitting unit 20 are made to emit light, and in the second illumination mode, each of the first light-emitting unit 10-1, the second light-emitting unit 10-2 to the second light-emitting unit 10-9 and the third light-emitting unit 20 is made to emit light. The light distribution angle in the first illumination mode is smaller than the light distribution angle in the second illumination mode. The first illumination mode is, for example, an illumination mode corresponding to telephoto illumination. The second illumination mode is, for example, an illumination mode corresponding to wide-angle illumination. As described above, in the first illumination mode (for example, the telephoto illumination mode), both the first light-emitting unit 10-1 and the third light-emitting unit 20 emit light. Therefore, compared with the light-emitting module that irradiates light with only the first light-emitting unit 10-1 in the first illumination mode, in the present embodiment, the amount of light on the irradiation surface S can be increased, so that the light-emitting module 100 that can irradiate light of desired characteristics can be provided.

[0050] In addition, Figures 1 to 3 In the illustrated example, the light emitting module 100 further includes a first lens 3 disposed above the first light source 1 . Figure 2The first lens 3 shown in the figure includes: a first incident surface 35, on which the light from the first light source 1 is incident, and protrudes in a direction close to the first light source 1; and a first exit surface 31, on which the light from the first light source is emitted. The first exit surface 31 is located on the side opposite to the first incident surface 35. Preferably, when viewed from above, each of the first incident surface 35 and the first exit surface 31 overlaps with the first light source 1 and does not overlap with the second light source 2. In addition, the light transmittance of the first lens 3 is preferably a property of having a transmittance of 60% or more for the peak wavelength of light emitted from the first light source 1. Through this structure, in the light emitting module 100, the situation where the light emitted from the second light source 2 is incident on the first incident surface 35 of the first lens 3 can be reduced. In addition, the stray light generated by the light from the second light source 2 incident on the first incident surface 35 can be reduced, and the quality of the irradiated light of the light emitting module 100 can be improved. Furthermore, the high quality of the irradiated light includes, for example, the symmetry of the light distribution pattern of the irradiated light and the reduction of irradiation of the light to unexpected areas on the irradiated surface S.

[0051] In addition, Figures 1 to 3 In the example shown, the light emitting module 100 further includes a second lens 4, which is disposed above the third light emitting unit 20 and has a second incident surface 41, which is opposite to the third light emitting surface 21 of the third light emitting unit 20 and is separated from the first incident surface 35 when viewed from above. Figure 1 and Figure 2 As shown, the second lens 4 has a substantially rectangular shape when viewed from above and can be a rod-shaped light-transmitting member extending in the Z direction. The light transmittance of the second lens 4 preferably has a property of having a transmittance of 60% or more for the peak wavelength of the light L2 emitted from the third light-emitting unit 20.

[0052] The light L2 emitted from the third light emitting portion 20 is incident into the interior of the second lens 4 through the second incident surface 41 of the second lens 4. The second lens 4 can guide the light L2 incident into the interior through the second incident surface 41 in the +Z direction, and emit it from the second exit surface 42. In addition, preferably, when viewed from above, the shape of the second incident surface 41 of the second lens 4 and the shape of the third light emitting surface 21 of the third light emitting portion 20 are substantially the same as each other. For example, the shape of the second incident surface 41 of the second lens 4 and the shape of the third light emitting surface 21 of the third light emitting portion 20 are substantially rectangular to each other. In addition, the shape of the second incident surface 41 of the second lens 4 and the shape of the third light emitting surface 21 of the third light emitting portion 20 may be similar to each other, or may be the same. Since the shape of the second incident surface 41 of the second lens 4 is substantially the same as the shape of the third light emitting surface 21 of the third light emitting unit 20 when viewed from above, it is easy to reduce the light loss caused by the light L2 from the third light emitting unit 20 not being incident on the second lens 4, compared with the case where the shape of the second incident surface 41 of the second lens 4 is different from the shape of the third light emitting surface 21 of the third light emitting unit 20 when viewed from above. Therefore, the light extraction efficiency of the light emitting module 100 can be improved. Note that, in addition, the shape of the second incident surface 41 of the second lens 4 and the shape of the third light emitting surface 21 of the third light emitting unit 20 can also be different from each other when viewed from above.

[0053] By providing the second lens 4 for guiding the light L2 emitted from the third light emitting unit 20, the light emitting module 100 can reduce the incidence of the light L2 emitted from the third light emitting unit 20 on the first incident surface 35 of the first lens 3. In addition, stray light generated by the light L2 from the third light emitting unit 20 being incident on the first incident surface 35 can be reduced. In addition, by providing the second lens 4, the light emitting module 100 can improve the light extraction efficiency of the light L2 emitted from the third light emitting unit 20, and can increase the light amount in the irradiation surface S.

[0054] In addition, Figures 1 to 3 In the example shown, the first optical axis 3C of the first lens 3 passing through the center of the first incident surface 35 intersects with the first light-emitting section 10-1, and the second optical axis 4C of the second lens 4 passing through the center of the second incident surface 41 intersects with the third light-emitting section 20. The second optical axis 4C is parallel to the first optical axis 3C. According to this structure, the light from the first light-emitting section 10-1 and the light from the third light-emitting section 20 are irradiated in the same direction, so on the irradiation surface S, the light from the first light-emitting section 10-1 and the light from the third light-emitting section 20 are easily overlapped, so that the light amount from the third light-emitting section 20 is easy to assist the light amount from the first light-emitting section 10-1. Thereby, the light amount of the first irradiation mode (for example, telephoto irradiation) of the light-emitting module 100 can be increased.

[0055] In addition, Figures 1 to 3In the example shown, the second lens 4 includes a second exit surface 42, and the light L2 incident on the second incident surface 41 from the third light emitting unit 20 is emitted from the second exit surface 42. The second incident surface 41 and the second exit surface 42 are preferably flat surfaces parallel to each other. By making the second incident surface 41 and the second exit surface 42 flat surfaces parallel to each other, the deviation of the illumination distribution of the light L2 from the third light emitting unit 20 after the light L2 from the third light emitting unit 20 passes through the second lens 4 can be reduced, and the control accuracy of the light L2 from the third light emitting unit 20 by the second lens 4 can be improved. Note that the second exit surface 42 may include any one of a plurality of concave and convex surfaces, convex surfaces, and concave surfaces. The plurality of concave and convex surfaces include any one of a plurality of concave portions, a plurality of convex portions, and a plurality of concave portions and a plurality of convex portions. The plurality of concave and convex surfaces may also be a Fresnel shape formed in a concentric circle shape. By having the second exit surface 42 include any one of a plurality of concave and convex surfaces, convex surfaces, and concave surfaces, the control accuracy of the light L2 from the third light emitting unit 20 by the second lens 4 can be improved.

[0056] In addition, Figures 1 to 3 In the example shown, the second incident surface 41 is located at a lower side than the first incident surface 35, and the second exit surface 42 is located at an upper side than the first incident surface 35. With this structure, the light L2 emitted from the third light emitting section 20 can be reduced from being incident on the first incident surface 35 of the first lens 3. Specifically, the light L2 emitted from the third light emitting section 20 is mainly incident on the second incident surface 41 of the second lens 4, and then irradiated onto the irradiation surface S via the second exit surface 42. Therefore, stray light generated by the light L2 from the third light emitting section 20 being incident on the first incident surface 35 can be reduced.

[0057] In addition, in the light emitting module 100, the current value input to the third light emitting section 20 is preferably less than or equal to the current value input to the first light emitting section 10-1. In other words, in the light emitting module 100, the current value input to the first light emitting section 10-1 is preferably greater than or equal to the current value input to the third light emitting section 20. The first light emitting section 10-1 and the plurality of second light emitting sections 10-2 to 10-9 in the first light source 1 can partially irradiate light to corresponding areas in the plurality of divided areas within the irradiable range on the irradiation surface S. On the other hand, the second light source 2 including the third light emitting section 20 is arranged to be separated from the first light source 1 in the horizontal direction. Therefore, although the light emitted from the second light source 2 overlaps at least partially with the irradiation area of ​​the first light emitting section 10-1 on the irradiation surface S, it is sometimes difficult to irradiate light to the divided areas in the irradiable range with high precision. Therefore, by making the current value input to the first light emitting unit 10-1 greater than or equal to the current value input to the third light emitting unit 20, the first light source 1 functions as the main light source in the light emitting module 100, and the second light source 2 functions as the auxiliary light source, thereby improving the irradiation accuracy of the partial irradiation of the light emitting module 100. Thus, for example, within the above-mentioned irradiable range, each area in the array can be partially irradiated with high accuracy using the first light source 1, while the central area can be auxiliaryly irradiated using the second light source 2. In the light emitting module 100, the current value input to the third light emitting unit 20 can be higher than the current value input to the first light emitting unit 10-1.

[0058] In addition, in the light emitting module 100, it is possible to switch between a first irradiation mode and a second irradiation mode, wherein in the first irradiation mode, only the first irradiation unit 10-1 and the third irradiation unit 20 are made to emit light, and in the second irradiation mode, each of the first irradiation unit 10-1, the second irradiation unit 10-2 to the second irradiation unit 10-9 and the third irradiation unit 20 is made to emit light. The light distribution angle of the light emitting module 100 in the first irradiation mode is smaller than the light distribution angle of the light emitting module 100 in the second irradiation mode. By reducing the light distribution angle of the first irradiation mode, the light emitted from the light emitting module 100 can reach a far distance compared with the light emitting module having a large light distribution angle in the first irradiation mode. As a result, for example, in a shooting device that uses the light emitted from the light emitting module 100 for shooting, it is easy to supply light with a sufficient amount of light when shooting at a telephoto.

[0059] In addition, as described above, the light emitting module 100 can be used as a light source for a flash. When the light emitting module 100 is used as a light source for a flash, particularly in the first irradiation mode, the temperature of the first light emitting unit 10-1 when emitting light can be reduced to exceed the allowable value of the junction temperature Tj. Thus, in this embodiment, a highly reliable light emitting module 100 for a flash can be provided to reduce malfunctions or damage caused by the temperature of the light emitting unit 10 exceeding the allowable value of the junction temperature Tj in a specific irradiation mode.

[0060] Furthermore, in the light emitting module 100, the planar size of the light emitting element included in the third light emitting section 20 may be larger than the planar size of the light emitting element included in the first light emitting section 10-1. By making the light emitting element included in the third light emitting section 20 larger than the light emitting element included in the first light emitting section 10-1, the heat or resistance value in the third light emitting section 20 may be reduced. Thus, the heat accumulated in the third light emitting section 20 may be reduced, and thus the failure or damage of the third light emitting section 20 may be reduced. Furthermore, by increasing the planar size of the light emitting element included in the third light emitting section 20, the electrode of the third light emitting section 20 or the wiring on the substrate side corresponding thereto also tends to be larger, and thus the heat generated in the third light emitting section 20 may be effectively released.

[0061] Note that in the light emitting module 100, the planar size of the light emitting element included in the third light emitting section 20 may be smaller than the planar size of the light emitting element included in the first light emitting section 10-1. By making the light emitting element included in the third light emitting section 20 smaller than the light emitting element included in the first light emitting section 10-1, the third light emitting section 20 can be made closer to a point light source, so that the light distribution control of the third light emitting section 20 can be easily performed.

[0062] In the light emitting module 100, the spacing distance between the first light emitting unit 10-1 and the third light emitting unit 20 is, for example, greater than 500 μm and less than 2500 μm, preferably greater than 1000 μm and less than 2000 μm. For example, the spacing distance between the first light emitting unit 10-1 and the third light emitting unit 20 is the shortest distance between the light emitting element of the first light emitting unit 10-1 and the light emitting element of the third light emitting unit 20 when viewed from above. In addition, the spacing distance between the first light emitting unit 10-1 and the third light emitting unit 20 is, for example, greater than 5 times and less than 30 times the spacing distance between the first light emitting unit 10-1 and the second light emitting units 10-3, 10-5, 10-6, and 10-8 adjacent to the first light emitting unit 10-1 in the X direction or the Y direction, preferably greater than 10 times and less than 20 times. For example, the spacing distance between the first light-emitting unit 10-1 and the second light-emitting unit 10-3 is the shortest distance between the light-emitting element of the first light-emitting unit 10-1 and the light-emitting element of the second light-emitting unit 10-3 when viewed from above. In addition, the distance from the light-emitting surface 11 of the first light-emitting unit 10-1 and the third light-emitting surface 21 of the third light-emitting unit 20 to the irradiation surface S is, for example, greater than 0.01m and less than 10m, preferably greater than 0.10m and less than 5m. For example, when the distance from the third light-emitting surface 21 of the third light-emitting unit 20 to the irradiation surface S is 0.3mm, the illumination of the third irradiation area Ar3 in the irradiation surface S is greater than 100 lux, preferably greater than 1000 lux.

[0063] (Detailed structure)

[0064] The following describes each structure of the light emitting module 100 in detail.

[0065] (Light-transmitting member 5)

[0066] like Figures 1 to 3 As shown, the light emitting module 100 may include a translucent member 5. The translucent member 5 includes an upper portion 51 opposite to the first emission surface 31 of the first lens 3, a cylindrical portion 52 supporting the end of the upper portion 51, and a leg portion 53 arranged in contact with the lower portion of the cylindrical portion 52. Figure 2 In the light-transmitting component 5 shown, the upper portion 51, the cylindrical portion 52, and the leg portion 53 are an integrated component. However, the upper portion 51, the cylindrical portion 52, and the leg portion 53 may also be separate components that are not connected to each other. The light-transmitting component 5 is configured to cover the first light source 1, the second light source 2, the first lens 3, and the second lens 4. The light-transmitting component 5 is joined to the first lens 3 by a first joining component 54 that is arranged in a ring shape at the outer edge of the first lens 3 when viewed from above. Figure 1 In the example shown, the light-transmitting member 5 has a substantially circular shape in a plan view, but the shape of the light-transmitting member 5 in a plan view may be substantially elliptical, substantially rectangular, substantially polygonal, or the like.

[0067] The light-transmitting member 5 is composed of at least one of a resin material or a glass material such as a polycarbonate resin, an acrylic resin, a silicone resin, an epoxy resin, etc., which is light-transmitting to the light emitted from the first light source 1 and the second light source 2. Note that the light-transmitting member 5 is preferably a property of having a light transmittance of 60% or more for the emission peak wavelength of the light emitted from the first light source 1 and the second light source 2, respectively.

[0068] exist Figures 1 to 3 In the example shown, the upper portion 51 is arranged above the first light source 1, the second light source 2, the first lens 3, and the second lens 4. The lower surface 510 of the upper portion 51 opposite to the first lens 3 may also be formed into a shape having light diffusivity, such as a concave-convex shape, a Fresnel shape, or a shape that refracts light. By forming a shape having light diffusivity, etc. in the lower surface 510, it is not easy to visually identify the inside of the light emitting module 100 from the outside of the light emitting module 100. Therefore, the aesthetic appearance of the light emitting module 100 can be improved. From the viewpoint of facilitating the control of the distribution of light emitted from the light emitting module 100, the shape formed in the lower surface 510 preferably does not have a light control function based on refraction or diffraction, but only has a function of diffusing or scattering light.

[0069] The cylinder portion 52 is a cylindrical portion that supports the upper portion 51. In a plan view, the leg portion 53 is a portion disposed outside the cylinder portion 52. The leg portion 53 can be used to fix the light-transmitting member 5 to a housing of a smartphone or the like.

[0070] (Wiring board 6)

[0071] like Figures 1 to 4 As shown, the light emitting module 100 may include a wiring substrate 6. The first light source 1 and the second light source 2 are arranged on the surface of the wiring substrate 6 at the +Z side. Figure 1 In the example shown, the wiring substrate 6 is a substantially circular plate-shaped member in a plan view. Figure 2 In the example shown, the wiring substrate 6 is bonded to the first lens 3 by a second bonding member 61 that is annularly arranged at a position opposite to the bottom surface 32 located at the outer edge of the first lens 3 on the upper surface of the wiring substrate 6. The wiring substrate 6 has wiring that can mount the first light source 1, the second light source 2, etc. Note that the shape of the wiring substrate 6 when viewed from above can be roughly rectangular, roughly elliptical, or roughly polygonal, etc.

[0072] The wiring substrate 6 preferably uses an insulating material as a base material, and preferably uses a material that is difficult to transmit light emitted from the first light source 1 and the second light source 2 or external light. In addition, the wiring substrate 6 preferably uses a material having a certain strength. Specifically, the wiring substrate 6 can be composed of a resin such as alumina, aluminum nitride, mullite, silicon nitride, etc., phenolic resin, epoxy resin, polyimide resin, BT resin (bismaleimide triazine resin), polyphthalamide, polyester resin, etc. as a base material.

[0073] The wiring substrate 6 has wiring arranged on the surface of a base material, for example. The wiring is made of a metal such as Cu, Ag, Au, Al, Pt, Ti, W, Pd, Fe, Ni, and / or an alloy containing at least these metals.

[0074] The light emitting module 100 is not limited to a single wiring substrate 6, but may be provided with a plurality of wiring substrates including, for example, a first wiring substrate and a second wiring substrate. The first light source 1 and the second light source 2 may be arranged on each wiring substrate. For example, the first light source 1 may be arranged on the first wiring substrate, and the second light source 2 may be arranged on the second wiring substrate.

[0075] (First light source 1 and second light source 2)

[0076] Next, refer to Figure 3 and Figures 5 to 7 The structures of the first light source 1 and the second light source 2 will be described in detail.

[0077] like Figure 3 As shown, the first light source 1 has nine light emitting units 10, and the light shielding member 15 can integrally hold a plurality of light emitting elements 12 and a plurality of wavelength conversion members 14. Figure 3 In the example shown, the light shielding member 15 integrally holds the nine light emitting elements 12 and the nine wavelength converting members 14 included in the nine light emitting units 10 .

[0078] exist Figure 3 In the example shown, the first light source 1 has nine light emitting units 10, namely, a first light emitting unit 10-1 and second light emitting units 10-2 to 10-9. The nine light emitting units 10 are arranged in a longitudinal direction, a transverse direction or an array shape when viewed from above. From another point of view, the nine light emitting units 10 are arranged along the X direction, or along the Y direction orthogonal to the X direction. Figure 3 In the example shown, nine light emitting units 10 are arranged along the X direction and the Y direction, respectively. Note that the first light source 1 is not limited to a light source having nine light emitting units 10, and may have any number of first light emitting units and second light emitting units, as long as it is a light source having a first light emitting unit and a plurality of second light emitting units arranged around the first light emitting unit.

[0079] The first light emitting unit 10-1 and the second light emitting units 10-2 to 10-9 each include a light emitting surface 11. When viewed from above, the light emitting surfaces 11 of the first light emitting unit 10-1 and the second light emitting units 10-2 to 10-9 are preferably arranged at Figure 2 The inner side of the first lens 3 shown in FIG. 1 (inner side than the outer shape of the first lens 3), more preferably, is arranged on the inner side of the first incident surface 35 of the first lens 3. This makes it easy for the light from the first light source 1 to enter the first lens 3. In addition, when viewed from above, the first light emitting unit 10-1 and the second light emitting units 10-2 to 10-9 overlap with the light emitting surfaces 11 included in each of them, so that Figure 3 In the example shown, the reference numerals of the first light emitting unit 10-1 and the second light emitting units 10-2 to 10-9 are recorded together with the reference numerals of the light emitting surface 11. In the following, when two or more light emitting surfaces are substantially identical or overlapped, the reference numerals may also be recorded together.

[0080] The width of the light emitting surface 11 along the X direction and along the Y direction is, for example, 30 μm or more and 2000 μm or less, preferably 100 μm or more and 1000 μm or less. The width of the light emitting surface 11 along the X direction and along the Y direction may be substantially equal or different. Figure 3 In the example shown, the light-emitting surfaces 11 of adjacent light-emitting units 10 are arranged to be separated from each other by a predetermined interval when viewed from above. From the perspective of the light-emitting characteristics of the first light source 1, the narrower the predetermined interval, the better. However, there is a limit to the interval between multiple light-emitting units 10 that can be installed. In order to obtain both good light-emitting characteristics and the interval between multiple light-emitting units 10 that can be installed, the predetermined interval is preferably not less than 10 μm and not more than 50 μm. Figure 3 In the example shown, the shape of the light emitting surface 11 when viewed from above is substantially rectangular, but the shape of the light emitting surface 11 when viewed from above may be substantially circular or elliptical, or may be substantially triangular or hexagonal, or other polygonal shape.

[0081] Figure 5 Yes means Figure 3 Schematic cross-sectional view of an example of the VV line in FIG. Note that the main structures of the first light-emitting unit 10-1, the second light-emitting units 10-2 to 10-9, and the third light-emitting unit 20 are the same. Therefore, by appropriately replacing the name and reference numerals of the second light-emitting unit 10-2, the third light-emitting unit 20 can be used. Figure 5 The description of the structure of the second light-emitting portion 10-2 can be applied to the first light-emitting portion 10-1, the second light-emitting portion 10-3 to the second light-emitting portion 10-9 and the third light-emitting portion 20 respectively.

[0082] exist Figure 5 In the example shown, the second light emitting unit 10-2 has a light emitting element 12, a wavelength conversion component 14 disposed on the light emitting element 12, and a light shielding component 15 covering the side surfaces of the light emitting element 12 and the side surfaces of the wavelength conversion component 14. The second light emitting unit 10-2 emits light from the light emitting surface 11 toward the top of the first light source 1. The light emitting surface 11 refers to the main light extraction surface of the second light emitting unit 10-2. The light emitted from the second light emitting unit 10-2 can be white light or light having a specific wavelength such as blue. The wavelength and chromaticity of the light emitted from the second light emitting unit 10-2 can be appropriately selected according to the use of the light emitting module 100.

[0083] The light emitting unit 10 and the third light emitting unit 20 can emit mixed color light in which the color of the light emitted from the light emitting element 12 and the color of the light emitted from the wavelength conversion member 14 are mixed by including the light emitting element 12 and the wavelength conversion member 14. In the light emitting unit 10 and the like, the degree of freedom of the color of the light emitted from the first light source 1 can be increased by the combination of the light emitting element 12 and the wavelength conversion member 14. In addition, since the light emitting unit 10 includes the light shielding member 15, the light emitted from the light emitting element 12 can be shielded by the light shielding member 15, thereby controlling the diffusion of the light emitted from the light emitting unit 10 and the like.

[0084] exist Figure 5 In the example shown, the second light emitting portion 10-2 is arranged on the surface on the +Z side of the wiring substrate 6, the upper surface thereof serves as the light emitting surface 11 and the surface opposite to the light emitting surface 11 serves as the mounting surface. The wavelength conversion member 14 is provided on the surface on the +Z side of the light emitting element 12. The light shielding member 15 covers the side surfaces of the light emitting element 12 and the side surfaces of the wavelength conversion member 14, except for the upper surface of the wavelength conversion member 14.

[0085] The light emitting element 12 has at least a pair of positive and negative electrodes 13 on the surface (ie, the lower surface) on the side opposite to the light emitting surface 11 .

[0086] The light emitting element 12 is preferably composed of various semiconductors such as III-V compound semiconductors and II-VI compound semiconductors. As the semiconductor, In X Al Y Ga 1-X-Y The light emitting element 12 may be a nitride semiconductor such as InN (0≤X, 0≤Y, X+Y≤1), or InN, AlN, GaN, InGaN, AlGaN, InGaAlN, etc. The light emitting element 12 is, for example, an LED or an LD. From the viewpoint of luminous efficiency and excitation of a wavelength conversion substance, the light emitting peak wavelength of the light emitting element 12 is preferably 400 nm to 530 nm, more preferably 420 nm to 490 nm, and even more preferably 450 nm to 475 nm.

[0087] The wavelength conversion member 14 is a member that is, for example, roughly rectangular 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 includes 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 composed of an inorganic substance such as a light-transmitting resin material, ceramics, and glass. The resin material can be a thermosetting resin such as a silicone resin, a silicone-modified resin, an epoxy resin, an epoxy-modified resin, or a phenolic resin. In particular, silicone resins or modified resins thereof that are excellent in light resistance and heat resistance are preferred. Note that the light transmittance here is preferably a property of transmitting more than 60% of the peak wavelength of light from the light emitting element 12. In addition, the wavelength conversion member 14 can use thermoplastic resins such as polycarbonate resins, acrylic resins, methylpentene resins, and polynovonin resins. For example, the wavelength conversion member 14 can be a material containing a wavelength conversion substance in a resin material, ceramics, glass, etc., a sintered body of a wavelength conversion substance, etc. The wavelength conversion member 14 can also contain a light diffusing substance in a resin material, ceramics, glass, etc. In addition, the wavelength conversion component 14 may be composed of a plurality of layers including a layer containing a wavelength conversion substance and a layer not containing a wavelength conversion substance. For example, the wavelength conversion component 14 may include a wavelength conversion layer containing a wavelength conversion substance, and a light diffusion layer located on the upper surface of the wavelength conversion layer and containing a light diffusion substance. The wavelength conversion component may include a light-transmitting layer that does not contain a wavelength conversion substance and a light diffusion substance instead of or in addition to the light diffusion layer.

[0088] As the wavelength conversion material contained in the wavelength conversion member 14, a yttrium aluminum garnet-based phosphor (for example, (Y, Gd) 3 (Al, Ga) 5 O 12 :Ce), lutetium aluminum garnet phosphors (e.g., Lu3(Al,Ga)5O 12 :Ce), terbium aluminum garnet phosphors (e.g., Tb3(Al,Ga)5O 12 : Ce), CCA-based phosphors (e.g., Ca10 (PO4)6Cl2:Eu), SAE-based phosphors (e.g., Sr4Al 14 O 25 :Eu), chlorosilicate-based phosphors (e.g., Ca8MgSi4O 16 C l2 :Eu), silicate-based phosphors (e.g., (Ba,Sr,Ca,Mg)2SiO4:Eu), β-sialon-based phosphors (e.g., (Si,Al)3(O,N)4:Eu) or α-sialon-based phosphors (e.g., Ca(Si,Al) 12 (O,N) 16 :Eu), etc., oxynitride-based phosphors, LSN-based phosphors (e.g., (La,Y)3Si6N 11 :Ce), BSESN-based phosphors (e.g., (Ba,Sr)2Si5N8:Eu), SLA-based phosphors (e.g., SrLiAl3N4:Eu), CASN-based phosphors (e.g., CaAlSiN3:Eu) or SCASN-based phosphors (e.g., (Sr,Ca)AlSiN3:Eu), etc., nitride-based phosphors, KSF-based phosphors (e.g., K2SiF6:Mn), KSAF-based phosphors (e.g., K2(Si 1-x Al x )F 6-x :Mn, where x satisfies 0 < x < 1.), or MGF-based phosphors (e.g., 3.5MgO·0.5MgF2·GeO2:Mn), etc., fluoride-based phosphors, 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), etc. The above wavelength conversion materials are particles. In addition, one of these wavelength conversion materials can be used alone, or two or more of these wavelength conversion materials can be used in combination.

[0089] The light emitting unit 10 and the third light emitting unit 20 have, for example, a blue light emitting element as the light emitting element 12. Since the wavelength conversion member 14 contains a wavelength conversion material that converts the wavelength of the light emitted from the light emitting element 12 into yellow, white light is emitted. For example, titanium oxide, barium titanate, alumina, silicon oxide, etc. can be used as the light diffusing material contained in the wavelength conversion member 14.

[0090] The light shielding member 15 is a member that covers the side surfaces of the light emitting element 12 and the side surfaces of 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 side surfaces of the wavelength conversion member 14. The upper surface of the wavelength conversion member 14 is exposed from the light shielding member 15 and serves as the light emitting surface 11 of the light emitting unit 10 or the third light emitting unit 20. In order to improve the light extraction efficiency, the light shielding member 15 is preferably formed of a member having a high light reflectivity. For example, the light shielding member 15 can use a resin material containing a light reflective substance such as a white pigment.

[0091] As light-reflective substances, 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, silicon oxide, etc. can be listed, and it is preferred to use one of them alone or use two or more of them in combination. In addition, as a resin material, it is preferred to use a resin material whose main component is a thermosetting resin as a base material, such as epoxy resin, epoxy modified resin, silicone resin, silicone modified resin and phenolic resin. Note that the shading component 15 may include a component that is light-absorbent to visible light. When the shading component 15 includes a component that is light-absorbent, the shading component 15 may contain a light-absorbing substance, such as carbon black.

[0092] The first light source 1 is electrically connected to the wiring 62 provided on the wiring substrate 6. The wiring substrate 6 preferably has the wiring 62 arranged on the surface. The wiring substrate 6 may also have the wiring 62 inside. By connecting the wiring 62 of the wiring substrate 6 to the positive and negative electrodes 13 of each light-emitting portion 10 via the conductive component 63, each light-emitting portion 10 included in the first light source 1 is electrically connected to the wiring substrate 6. Note that the wiring 62 of the wiring substrate 6 is set in structure, size, etc. according to the structure and size of the electrode 13 of each light-emitting portion 10. On the wiring substrate 6, in addition to the first light source 1, a second light source 2 may be arranged. In this case, the second light source 2 is arranged on the upper surface of the wiring substrate 6, separated from the first light source 1 in the horizontal direction. Note that the first light source 1 and the second light source 2 may also be arranged on different wiring substrates, respectively.

[0093] Figure 6 1 is a schematic cross-sectional view showing a first example of the structure of the first light source 1 . Figure 7 2 is a schematic cross-sectional view showing a second example of the structure of the first light source 1 . Figure 6 and Figure 7 The cross section of the first light source 1 including the first light emitting portion 10 - 1 , the second light emitting portion 10 - 5 and the second light emitting portion 10 - 6 is schematically shown.

[0094] exist Figure 6In the first example shown, the first light source 1 includes a wavelength conversion member 14 for each of the first light emitting section 10-1, the second light emitting section 10-5, and the second light emitting section 10-6. The light emitting elements 12 included in the first light emitting section 10-1, the second light emitting section 10-5, and the second light emitting section 10-6 are arranged to be separated from each other via a light shielding member 15. In addition, the wavelength conversion members 14 included in the first light emitting section 10-1, the second light emitting section 10-5, and the second light emitting section 10-6 are arranged to be separated from each other via a light shielding member 15.

[0095] On the other hand, Figure 7 In the second example shown, the first light source 1 has a common wavelength conversion member 14 for each of the first light emitting section 10-1, the second light emitting section 10-5, and the second light emitting section 10-6. The light emitting element 12 of each of the first light emitting section 10-1, the second light emitting section 10-5, and the second light emitting section 10-6 is arranged to be separated from each other via the light shielding member 15. On the other hand, in the second example, one wavelength conversion member 14 is arranged to cover the entire light emitting element 12 of each of the first light emitting section 10-1, the second light emitting section 10-5, and the second light emitting section 10-6.

[0096] (First lens 3 and second lens 4)

[0097] Next, refer to Figures 8 to 10 The structures of the first lens 3 and the second lens 4 will be described in detail. Figure 8 It is a schematic plan view showing an example of the structure of the first lens 3 . Fig. 9 It is a schematic plan view showing an example of the structure of the first lens 3 . Fig.10 Yes means Figure 8 A schematic cross-sectional view of an example of line XX in FIG. Note that Fig. 9 Some lines are omitted.

[0098] exist Figure 8 In the example shown, the shape of the outer edge of the first lens 3 when viewed from above is approximately circular. However, the shape of the outer edge of the first lens 3 when viewed from above may also be approximately rectangular, approximately elliptical, or approximately polygonal. In addition, the shape of the outer edge of the first lens 3 when viewed from above may also be a rotationally symmetrical shape. Considering that the photographic range of a general photographic device is approximately rectangular, the shape of the outer edge of the first lens 3 when viewed from above is preferably a four-fold rotationally symmetrical shape or a two-fold rotationally symmetrical shape.

[0099] exist Fig. 9 and Fig.10In the example shown, the first lens 3 includes a first exit surface 31 that protrudes on the opposite side of the first incident surface 35, that is, on the side where the light from the first light source 1 is emitted from the first lens 3 and on the side opposite to the side where the first light source 1 is located. Note that in the first lens 3, the size of the first lens 3 when viewed from above, the size of the radius of curvature of the first incident surface 35, the size of the radius of curvature of the convex surface of the first exit surface 31, the thickness of the lens, the shapes of the convex surfaces of the first incident surface 35 and the first exit surface 31, etc. can be appropriately changed.

[0100] The first lens 3 may include at least one of a resin material such as polycarbonate resin, acrylic resin, silicone resin, epoxy resin, or a glass material that is translucent to the light L emitted from the first light source 1. When the first lens 3 and the second lens 4 are an integral component, the second lens 4 may be made of the same material as the first lens 3.

[0101] exist Figures 8 to 10 In the example shown, the first lens 3 and the second lens 4 are an integral component. For example, the first lens 3 and the second lens 4 are composed of a light-transmitting resin material and are manufactured integrally by injection molding or the like. Note that the light transmittance of the first lens 3 and the second lens 4 preferably has a property of having a transmittance of 60% or more for the peak wavelengths of the light L1 from the first light-emitting unit 10-1 and the light L2 from the third light-emitting unit 20. By making the first lens 3 and the second lens 4 an integral component, the light-emitting module 100 can be easily assembled. When the first lens 3 and the second lens 4 are separate components, the first lens 3 and the second lens 4 can be manufactured, for example, by different molding processes. In addition, when the first lens 3 and the second lens 4 are separate components, the first lens 3 and the second lens 4 can be configured separately in the horizontal direction.

[0102] (Modification of the Second Lens 4)

[0103] Various modified examples of the second lens 4 will be described below.

[0104] (First Modification Example of Second Lens 4)

[0105] Fig.11 : is a schematic cross-sectional view showing a first modified example of the second lens 4 . Fig.11 A cross section including a second optical axis 4C of the second lens 4 in the vicinity of the second incident surface 41 of the second lens 4 is shown.

[0106] The difference between the second lens 4 in the first embodiment and the second lens 4 in the first variation is that the second lens 4 in the first variation includes a total reflection portion 43, which is located between the second incident surface 41 and the Fig.10The total reflection portion 43 is located between the second exit surface 42 shown in the figure, and totally reflects the light from the third light emitting unit 20 incident on the second incident surface 41. The total reflection portion 43 is located below the lowest part of the first incident surface 35 of the first lens 3. The inclination of the surface of the total reflection portion 43 is determined in such a way that the light from the third light emitting unit 20 incident on the second incident surface 41 is totally reflected. Fig.11 In the example shown, the total reflection portion 43 includes a curved surface. Therefore, in the second lens 4 of the first modified example, the cross-sectional area perpendicular to the second optical axis 4C decreases nonlinearly as it approaches the third light emitting portion 20.

[0107] By making the second lens 4 of the first modified example include the total reflection portion 43, the light from the third light emitting portion 20 incident on the second incident surface 41 is not easy to leak from the side surface of the second lens 4. As a result, it is possible to reduce the situation where the light from the third light emitting portion 20 incident on the second incident surface 41 leaks from the side surface of the second lens 4 and is incident on the first incident surface 35 of the first lens 3. As a result, stray light caused by the light from the third light emitting portion 20 incident on the first lens 3 can be reduced.

[0108] In addition, by adjusting the inclination angle of the total reflection portion 43, as shown in FIG. Figure 4 As shown, in the irradiation surface S irradiated with the light emitted from the light emitting module 100, the position of the second irradiation area Ar2 irradiated by the light L2 from the third light emitting unit 20 can be closer to the first irradiation area Ar1 irradiated by the light L1 from the first light emitting unit 10-1. Thus, the light amount of the light L2 from the third light emitting unit 20 can be used to assist the light amount of the light L1 from the first light emitting unit 10-1, so as to increase the light amount of the telephoto irradiation performed by the light emitting module 100.

[0109] (Second Modification Example of Second Lens 4)

[0110] Fig.12 : is a schematic cross-sectional view showing a second modified example of the second lens 4 . Fig.12 A cross section including the second optical axis 4C of the second lens 4 in the vicinity of the second emission surface 42 of the second lens 4 is shown.

[0111] like Fig.12 As shown, the second lens 4 of the second modified example is different from the second lens 4 in the first embodiment in that the second exit surface 42 includes a plurality of concavoconvex portions 44. The plurality of concavoconvex portions 44 include a plurality of concave portions, a plurality of convex portions, and any one of a plurality of concave portions and a plurality of convex portions. The plurality of concavoconvex portions 44 may include a Fresnel shape, etc.

[0112] The second emission surface 42 includes a plurality of concavo-convex portions 44, so that the light emitted from the second lens 4 is diffused through the plurality of concavo-convex portions 44. Thus, it is possible to reduce the uneven illumination of the light emitted from the second lens 4. In addition, since the second emission surface 42 includes a plurality of concavo-convex portions 44, it is difficult to identify the interior of the light emitting module 100 through the second emission surface 42, and thus the aesthetic appearance of the light emitting module 100 can be improved.

[0113] (Third Modification Example of Second Lens 4)

[0114] Fig.13 It is a schematic cross-sectional view showing a third modified example of the second lens 4 . Fig.13 A cross section including a second optical axis 4C of the second lens 4 is shown near the second emission surface 42 of the second lens 4 .

[0115] like Fig.13 As shown, the second lens 4 of the third modified example is different from the second lens 4 of the first embodiment in that the second emission surface 42 includes a convex surface 45. The convex surface 45 is a curved surface convex on the side opposite to the side where the third light emitting unit 20 is located.

[0116] Since the second emission surface 42 includes the convex surface 45, the curvature radius of the convex surface 45 can be used to control the light distribution of the light emitted from the second lens 4. As a result, the degree of freedom of controlling the light distribution of the light emitted from the second lens 4 can be increased. The convex surface 45 can be, for example, a plano-convex lens surface or a cylindrical lens surface. Fig.13 In the second lens 4 shown, for example, among the light L2 emitted from the third light emitting section 20 , the light passing through the second optical axis 4C has the highest light emission intensity.

[0117] (Fourth Modification Example of Second Lens 4)

[0118] Fig.14 It is a schematic cross-sectional view showing a fourth modified example of the second lens 4 . Fig.14 A cross section including a second optical axis 4C of the second lens 4 is shown near the second emission surface 42 of the second lens 4 .

[0119] like Fig.14 As shown, the second lens 4 of the fourth modified example is different from the second lens 4 of the first embodiment in that the second emission surface 42 includes a concave surface 46. The concave surface 46 is a curved surface that is recessed on the side where the third light emitting unit 20 is located. The concave surface 46 is, for example, a plano-concave lens surface.

[0120] Since the second emission surface 42 includes the concave surface 46, the light distribution of the light emitted from the second lens 4 can be controlled by the curvature radius of the concave surface 46. Thus, the degree of freedom in controlling the light distribution of the light emitted from the second lens 4 can be increased.

[0121] [Modifications]

[0122] Next, various modifications of the light emitting module according to the embodiment will be described. Note that the same names and reference numerals as those in the already described embodiment denote the same or homogeneous components or structures, and detailed descriptions thereof will be omitted as appropriate.

[0123] <Light-emitting module according to first modified example>

[0124] Fig.15 1 is a schematic cross-sectional view showing an example of a light emitting module 100a according to a first modification. Figure 1 The top view of the light emitting module 100 is shown similarly. Fig.15 Indicates that the corresponding Figure 1 The cross section along line II-II in FIG.

[0125] In the light emitting module 100a, the first light emitting part 10-1 includes a first phosphor layer, the second light emitting parts 10-2 to 10-9 each include a second phosphor layer, and the third light emitting part 20 includes a third phosphor layer. The phosphor contained in the third phosphor layer is different from the phosphor contained in the first phosphor layer. The first light emitting part 10-1 and the third light emitting part 20 can be driven separately. In the light emitting module 100a, the above points are different from the light emitting module 100 according to the above embodiment.

[0126] exist Fig.15 In the example shown, the first phosphor layer is included in Figure 5 The wavelength conversion component 14 of the first light-emitting section 10-1 shown in the figure is included. The second phosphor layer is included in the wavelength conversion component 14 of the second light-emitting section 10-2 to the second light-emitting section 10-9. The third phosphor layer is included in the wavelength conversion component 14 of the third light-emitting section 20. In the first light-emitting section 10-1 and the second light-emitting section 10-2 to the second light-emitting section 10-9, for example, by mixing the light emitted from each of the first phosphor layer and the second phosphor layer with the light emitted from the light-emitting element 12, white light can be irradiated. For example, in the third light-emitting section 20, by mixing the light emitted from the third phosphor layer with the light emitted from the light-emitting element 12, amber light can be irradiated.

[0127] For example, when performing photography focused on a person in a shooting device using the first illumination mode of the light emitting module, it is preferable to make the color temperature of the light irradiated to the person as the shooting object closer to the color temperature of the ambient light. In the light emitting module 100a, the balance of the current values ​​respectively applied to the first light emitting unit 10-1 and the third light emitting unit 20 is adjusted, and the light from the first light emitting unit 10-1 and the light from the third light emitting unit 20 are adjusted in color, so that light of the desired color temperature can be irradiated. Because light that has been color-adjusted by the light from the first light emitting unit 10-1 and the light from the third light emitting unit 20 can be irradiated, the color temperature of the light irradiated from the light emitting module 100a to the person can be made closer to the color temperature of the ambient light. As a result, in the shooting device, shooting can be performed using illumination light of a natural color.

[0128] <Light-emitting module according to second modification>

[0129] Reference Figures 16 to 18 A light emitting module according to a second modification example will be described. Fig.16 1 is a schematic cross-sectional view showing an example of a light emitting module 100b according to a second modification. The top view of the light emitting module 100b is similar to the top view of the light emitting module 100b except that it includes the third light emitting unit 20-2 and the second lens 4-2. Figure 1 The lighting modules 100 shown are identical. Fig.16 Representation and Figure 1 The cross section corresponding to the II-II line in . Fig.17 It is a schematic plan view showing a first example of the second light source 2 included in the light emitting module 100 b. Fig.18 2 is a schematic top view showing a second example of the second light source 2 included in the light emitting module 100b. Fig.17 and Fig.18 The light emitting module 100 b is shown in a state where the first lens 3 , the second lens 4 , and the light-transmitting member 5 are removed.

[0130] In the light emitting module 100b, the second light source 2 includes a plurality of third light emitting units 20 symmetrically arranged around the first light source 1 in a plan view. The light emitting module 100b includes at least one second lens arranged above the plurality of third light emitting units 20 corresponding to the plurality of third light emitting units 20. The light emitting module 100b is different from the light emitting module 100 of the above embodiment in the above points.

[0131] exist Fig.16 and Fig.17In the example shown, the second light source 2 includes two third light emitting units 20 arranged around the first light source 1 in a plan view. The two third light emitting units 20 include a third light emitting unit 20-1 and a third light emitting unit 20-2. The light emitting module 100b includes a second lens 4-1 arranged above the third light emitting unit 20-1 and corresponding to the third light emitting unit 20-1, and includes a second lens 4-2 arranged above the third light emitting unit 20-2 and corresponding to the third light emitting unit 20-2. Note that Fig.17 In the example shown, in order to indicate that the third light emitting unit 20-1 and the third light emitting unit 20-2 are included in the two third light emitting units 20, the reference numerals of the third light emitting unit 20-1 and the third light emitting unit 20 are recorded together, and the reference numerals of the third light emitting unit 20-2 and the third light emitting unit 20 are recorded together. The second lens 4-1 and the second lens 4-2 may be of the same shape or of different shapes. When the second lens 4-1 and the second lens 4-2 are of different shapes, for example, the second lens 4-1 is a shape corresponding to the third light emitting unit 20-1, and the second lens 4-2 is a shape corresponding to the third light emitting unit 20-2.

[0132] exist Fig.18 In the example shown, the second light source 2 has four third light emitting units 20 arranged around the first light source 1 in a plan view. The four third light emitting units 20 include a third light emitting unit 20-1, a third light emitting unit 20-2, a third light emitting unit 20-3, and a third light emitting unit 20-4. The light emitting module 100b may include at least one second lens 4 arranged above the four third light emitting units 20 in correspondence with the four third light emitting units 20. Note that in Fig.18 In the example shown, in order to indicate that the third light emitting units 20-1 to 20-4 are included in the four third light emitting units 20, the third light emitting unit 20-1 is recorded together with the reference numeral of the third light emitting unit 20, the third light emitting unit 20-2 is recorded together with the reference numeral of the third light emitting unit 20, the third light emitting unit 20-3 is recorded together with the reference numeral of the third light emitting unit 20, and the third light emitting unit 20-4 is recorded together with the reference numeral of the third light emitting unit 20. The second lenses 4 may have the same shape or different shapes.

[0133] The second lens 4 may not be disposed in a one-to-one correspondence on the plurality of third light emitting units 20. For example, the second lens 4 may be a single annular lens disposed above each of the plurality of third light emitting units 20 in a plan view.

[0134] In the light emitting module 100b, by providing a plurality of third light emitting units 20 symmetrically arranged with the first light source 1 as the center, the deviation of the illuminance distribution of the light emitted from the third light emitting unit 20 can be reduced on the irradiation surface S irradiated by the light emitted from the light emitting module 100b. In addition, it is easy to reduce the deviation of the stray light distribution in the light from the first light source 1 on the irradiation surface S. In addition, since the structure of the plurality of third light emitting units 20 that can be visually identified through the first lens 3 is symmetrical with the first light source 1 as the center, the aesthetic appearance of the light emitting module 100b can be improved.

[0135] <Light-emitting module according to third modified example>

[0136] Fig.19 1 is a schematic cross-sectional view showing an example of a light emitting module 100c according to a third modified example. Figure 1 The top view of the light emitting module 100 is shown similarly. Fig.19 Representation and Figure 1 The cross section corresponding to the II-II line in .

[0138] In the light emitting module 100c, by reflecting the light emitted from the third light emitting unit 20 and guided inside the second lens 4 by the reflective film 16, it is possible to reduce the leakage of the light guided inside the second lens 4 to the first lens 3 side. Thus, stray light generated by the light guided inside the second lens 4 leaking from the second lens 4 and incident on the first incident surface 35 of the first lens 3 can be reduced. In addition, by reflecting the light that is not incident on the first incident surface 35 of the first lens 3 among the light emitted from the first light source 1 by the reflective film 16, it is easy to increase the light amount of the irradiated light of the first light source 1 on the irradiation surface S. Note that the reflective film 16 may be provided on the entire side surface of the second lens 4, or may be provided only on the side surface on the first lens 3 side among the entire side surface of the second lens 4.
