Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0042] It should be noted that the terms "first", "second", etc. in the description and claims of the present utility model and the above-mentioned accompanying drawings are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present utility model described herein can be implemented in an order other than those illustrated or described herein.

[0043] Figure 1 is a schematic diagram of the first-angle structure of the first light source device provided according to an embodiment of the present utility model, Figure 2 is a connection schematic diagram of a light source device provided according to an embodiment of the present utility model.

[0044] As Figure 1 and Figure 2 shown, the light source device 10 includes:

[0045] a substrate 1, a light-emitting structure 2, and a control unit 3;

[0046] The light-emitting structure 2 is disposed on one side of the substrate 1;

[0047] The control unit 3 is electrically connected to the light-emitting structure 2 and is used to control the light-emitting structure 2 to emit scanning light in a first preset band according to the light-emitting requirement; wherein, the first preset band includes at least one band among the ultraviolet band, the infrared band, and the visible light band.

[0048] Among them, the light-emitting structure 2 is fixedly disposed on the substrate 1, and the control unit 3 may or may not be disposed on the substrate 1. The control unit 3 is electrically connected to the light-emitting structure 2 to control the light output of the light-emitting structure 2. Among them, the light-emitting requirement may be the modeling image requirement in a three-dimensional modeling system, and can be specifically determined according to the object to be measured. For example, it is required that the three-dimensional modeling system generates a modeling image in a darker environment. Since infrared imaging has better resolution in low-light environments, the light-emitting requirement is light in the infrared band.

[0049] Among them, the first preset band includes at least one of the ultraviolet light band, the infrared light band, and the visible light band. That is, the scanning light emitted by the light-emitting structure 2 can be light in the ultraviolet light band, light in the infrared light band, light in the visible light band, or a combined light of the above bands. That is, the light source device 10 is a wide-spectrum light source device 10. Compared with the light source device 10 for three-dimensional modeling in the prior art, the light source device 10 in the embodiment of the present invention can cover a wider spectral range.

[0050] Exemplarily, in a three-dimensional modeling scenario where it is required to obtain certain materials, the modeling images captured based on visible light cannot present specific details. For example, visible light cannot penetrate thin clothing or the surface layer of the skin to reveal the underlying detailed structures such as blood vessels or textures; visible light also cannot present skin blemishes, textures, and pigmentation. Therefore, at this time, the scanning light in the infrared light band and the scanning light in the ultraviolet light band can be combined to achieve a more refined acquisition of the modeling images.

[0051] In a three-dimensional modeling scenario with relatively dim light, since the infrared light band has a good imaging effect in a dim environment, the scanning light in the infrared light band is combined to obtain the modeling images, so that clear images can be obtained even in a dim environment, improving the accuracy of obtaining modeling images in a night scene or a low-light scene.

[0052] In a three-dimensional modeling scenario where it is required to capture thermal images, since infrared imaging can capture the thermal radiation of the object to be measured and then generate thermal images, the scanning light in the infrared light band is combined to obtain the modeling images, simulating the reactions of the object to be measured under different temperature conditions and expanding the application range of three-dimensional modeling.

[0053] Since some substances emit fluorescence under ultraviolet light irradiation, this characteristic can be used to increase the visibility of certain details of the object to be measured in a three-dimensional modeling scenario and also improve the visual effect of the three-dimensional modeling images of the object to be measured.

[0054] The technical solution of the embodiment of the present invention expands the spectrum of the light source device in the three-dimensional modeling system, so that the light source device can also emit scanning light in the ultraviolet light band and the infrared light band. At the same time, according to the application scenario of the three-dimensional modeling system, the light source device can be controlled to emit scanning light in different bands, thereby improving the imaging effect of the three-dimensional modeling system.

[0055] Optionally, Figure 3 is the second-angle structural schematic diagram of the first light source device provided according to the embodiment of the present invention. Combining Figure 1 、 Figure 2 and Figure 3 as shown, the first preset band includes the ultraviolet light band, the infrared light band, and the visible light band.

[0056] The light-emitting structure 2 includes a plurality of light-emitting diodes 21; the light-emitting region 4 includes a plurality of sub-light-emitting regions 40, and the light-emitting bands of the light-emitting diodes 21 in different sub-light-emitting regions 40 are different.

[0057] Among them, the light-emitting structure 2 includes a plurality of light-emitting diodes 21. The wavelength of the light emitted by each light-emitting diode 21 is fixed, and the wavelengths of the light that the light-emitting diodes 21 of the light-emitting structure 2 can emit include the ultraviolet light band, the infrared light band, and the visible light band. Among them, the light-emitting diodes 21 that emit light in the ultraviolet light band are arranged in one sub-light-emitting region 40, the light-emitting diodes 21 that emit light in the infrared light band are arranged in one sub-light-emitting region 40, and the light-emitting diodes 21 that emit light in the visible light band are arranged in one sub-light-emitting region 40.

[0058] Specifically, when the control unit 3 needs to control the scanning light to emit a wavelength in the ultraviolet light band, the control unit 3 controls the light-emitting diodes 21 in the corresponding sub-light-emitting region 40 to turn on; when the control unit 3 needs to control the scanning light to emit a wavelength in the infrared light band, the control unit 3 controls the light-emitting diodes 21 in the corresponding sub-light-emitting region 40 to turn on; when the control unit 3 needs to control the scanning light to emit a wavelength in the visible light band, the control unit 3 controls the light-emitting diodes 21 in the corresponding sub-light-emitting region 40 to turn on. Figure 4 It is the spectrogram of a light source device 10 provided according to an embodiment of the present invention. As Figure 4 shown, the entire band of the scanning light emitted by the light source device 10 is the full spectrum.

[0059] In some embodiments, the light-emitting diodes 21 in the sub-light-emitting region 40 corresponding to the visible light band include red light-emitting diodes, green light-emitting diodes, and blue light-emitting diodes, and the color rendering degrees of red light, green light, and blue light are close to 100, so that when the control unit 3 controls the light-emitting diodes 21 in the sub-light-emitting region 40 corresponding to the visible light band to turn on, the environment of natural light can be simulated.

[0060] The technical solution of the embodiment of the present invention, by setting the light-emitting structure to include light-emitting diodes and dividing the corresponding sub-light-emitting regions according to the light-emitting wavelengths of the light-emitting diodes, when the scanning light in the ultraviolet light band, the infrared light band, or the visible light band is required to emit light, the light-emitting diodes in the corresponding band can emit light concentratedly, improving the imaging effect of the three-dimensional modeling system.

[0061] Optionally, Figure 5 It is the first-angle structural schematic diagram of the second light source device provided according to an embodiment of the present invention. As shown in combination with Figure 2 and Figure 5 shown, the first preset band includes the ultraviolet light band, the infrared light band, and the visible light band;

[0062] The light-emitting structure 2 includes an excitation diode 22 and a fluorescent layer 5 located on the light-emitting side of the excitation diode;

[0063] The light-emitting region 4 includes a plurality of sub-light-emitting regions 40. The emission wavelength bands of the excitation diodes 22 in different sub-light-emitting regions 40 are the same, the peak wavelengths of the fluorescent layers 5 in different sub-light-emitting regions 40 are different, and the peak wavelength of the excitation diode 22 is less than the peak wavelength of the fluorescent layer 5.

[0064] Among them, the excitation diode 22 can be used to emit initial light. When the initial light is incident on the fluorescent layer 5, the phosphor in the fluorescent layer 5 can be excited to achieve wavelength conversion, and then the simultaneous emission of light in different wavelength bands can be realized. Since the peak wavelengths of the fluorescent layer 5 are different, the results of wavelength conversion are different, and thus the emission of light in different wavelength bands can be realized.

[0065] Specifically, the light-emitting region 4 includes a plurality of sub-light-emitting regions 40. The emission wavelengths of the excitation diodes 22 in different sub-light-emitting regions 40 are the same, but the corresponding fluorescent layers 5 in different sub-light-emitting regions 40 are different, so that the wavelength conversion of the same light incident on the fluorescent layers 5 with different peak wavelengths is different, and thus the emission of light in different wavelength bands from different sub-light-emitting regions 40 can be realized. It can be understood that in the embodiments of the present invention, the peak wavelength of the fluorescent layer 5 and the wavelength of the initial light can be set according to the ultraviolet light band, the infrared light band, and the visible light band, and the embodiments of the present invention do not limit this.

[0066] In the technical solution of the embodiments of the present invention, by setting the same excitation diodes and different fluorescent layers in different sub-light-emitting regions, light beams in different wavelength bands are emitted from different sub-light-emitting regions. The control unit can control the light emission of the excitation diodes in the corresponding sub-light-emitting regions according to the light emission requirements, and thus realize the concentrated light emission in the corresponding wavelength bands, improving the imaging effect of the three-dimensional modeling system.

[0067] Optionally, Figure 6 is a schematic structural diagram of a first angle of a third light source device provided according to an embodiment of the present invention. Combining Figure 6 and Figure 2 as shown, the first preset wavelength band includes the ultraviolet light band, the infrared light band, and the visible light band;

[0068] The light-emitting structure 2 includes an excitation diode 22 and a fluorescent layer 5 located on the light-emitting side of the excitation diode 22. The fluorescent layer 5 includes a first fluorescent layer 51, a second fluorescent layer 52, and a third fluorescent layer 53; the first fluorescent layer 51, the second fluorescent layer 52, and the third fluorescent layer 53 are stacked along the light-emitting direction;

[0069] The peak wavelength of the first fluorescent layer 51 is less than the peak wavelength of the second fluorescent layer 52; the peak wavelength of the second fluorescent layer 52 is less than the peak wavelength of the third fluorescent layer 53.

[0070] Among them, the first fluorescent layer 51, the second fluorescent layer 52 and the third fluorescent layer 53 are stacked so that the initial light of the excitation diode 22 first enters the first fluorescent layer 51 for wavelength conversion, then enters the second fluorescent layer 52 for wavelength conversion, and then enters the third fluorescent layer 53 for wavelength conversion. Since the light incident on the fluorescent layer 5 cannot be completely converted in wavelength, the light emitted by the light-emitting structure 2 includes both the initial light of the excitation diode 22, the first converted light converted by the first fluorescent layer 51, the second converted light converted by the second fluorescent layer 52, and the third converted light converted by the third fluorescent layer 53.

[0071] In some embodiments, the light emitting structure 2 further includes a light guide layer 54; the light guide layer 54 is used to receive the light emitted by the first fluorescent layer 51, the second fluorescent layer 52 and the third fluorescent layer 53 and merge them into scanning light for emission. The light guide layer 54 can be used to merge light of different wavelengths to make the wavelength of the scanning light more uniform.

[0072] For example, when the ratios of the red light band, the green light band, and the blue light band in the initial light of the excitation diode 22, the first converted light converted by the first fluorescent layer 51, the second converted light converted by the second fluorescent layer 52, and the third converted light converted by the third fluorescent layer 53 are similar to those of sunlight, the light finally emitted by the light-emitting structure 2 is white light, which can simulate the natural light environment.

[0073] The technical solution of the embodiment of the utility model expands the application scenarios of the three-dimensional modeling system by stacking the first fluorescent layer, the second fluorescent layer and the third fluorescent layer so that the initial light emitted by the excitation diode is excited in sequence and the light-emitting structure emits mixed light.

[0074] Optional, continue to refer to Figure 3 As shown, the light emitting area 4 includes a plurality of sub-light emitting areas 40;

[0075] The projection of each sub-light-emitting region 40 on the substrate 1 is annular and the centers of each sub-light-emitting region 40 coincide with each other.

[0076] The projection of each sub-light-emitting area 40 on the substrate 1 is annular, and the annular setting makes the emission angle of the scanning light more uniform, thereby improving the imaging effect of the object to be measured. The center of each sub-light-emitting area 40 is set to coincide, so that the center of the emission position of the sub-light-emitting area 40 is the same. When irradiating the object at the same angle, no matter what band of scanning light is used, the incident angle of the scanning light can be guaranteed to be the same, avoiding the problem that the center of the sub-light-emitting area 40 does not coincide, resulting in the change of the incident angle of the light when changing the scanning light of different bands, thereby causing the problem of deviation in the required imaging position.

[0077] In the technical solution of the embodiment of the present utility model, the sub-light-emitting regions are set to be annular and the centers of each sub-light-emitting region coincide. After the position of the light source device is fixed, when replacing light rays of different wavelengths, the incident angle of the light rays does not change, ensuring the consistency of the three-dimensional modeling imaging angles of different wavelengths.

[0078] Optionally, the light-emitting structure includes a light-emitting layer and an electrode;

[0079] The light-emitting layer is located on the side of the electrode away from the substrate. (Not shown in the figure)

[0080] Among them, since the light-emitting layer is located on the side of the electrode away from the substrate, the light-emitting structure is flip-chip mounted on the substrate, and the wiring in the substrate can be directly welded to the electrode, eliminating the step of wire bonding on the electrode and then connecting to the wiring in the substrate when the light-emitting structure is face-up mounted, saving the process flow.

[0081] Optionally, continue to refer to Figure 6 As shown, the light source device 10 further includes a packaging layer 6;

[0082] The packaging layer 6 is disposed on the side of the light-emitting structure 2 away from the substrate 1 for covering the light-emitting structure 2 and the substrate 1.

[0083] Among them, the packaging layer 6 can be used to seal the substrate 1 and the light-emitting structure 2 to prevent the light-emitting structure 2 from being interfered by water vapor in the environment and resulting in a reduced lifespan.

[0084] In the technical solution of the embodiment of the present utility model, by disposing a packaging layer on the side of the light-emitting structure away from the substrate, the packaging layer seals the light-emitting structure, preventing the light-emitting structure from being in contact with water vapor for a long time and resulting in a reduced lifespan, improving the reliability and lifespan of the light source device 10.

[0085] Based on the same inventive concept, Figure 7 is a connection schematic diagram of a three-dimensional modeling system according to an embodiment of the present utility model. As Figure 1 shown, the embodiment of the present utility model further provides a three-dimensional modeling system, which includes a light source device 10;

[0086] It further includes: an imaging unit 7;

[0087] The object to be measured 8 is disposed on the propagation path of the scanning light and reflects the scanning light into the imaging unit 7;

[0088] The imaging unit 7 is configured to receive the scanning light reflected by the object to be measured 8 and generate a modeling image.

[0089] Among them, the imaging unit 7 is used to generate a modeling image. The light source device 10 and the imaging unit 7 are arranged at corresponding positions so that the scanning light can be incident on the object to be measured 8, and the object to be measured 8 reflects the scanning light into the imaging unit 7, and the imaging unit 7 generates a modeling image according to the scanning light reflected by the object to be measured 8.

[0090] It can be understood that the 3D modeling system can be a digital human 3D modeling system. Since the digital human modeling has high requirements for the realism and vision of the modeling image, by setting lights of different bands and applying lights of different bands to different parts of the digital human, the fineness and vividness of the modeling image can be improved, making it have a wider application prospect in virtual reality, movie special effects and game development.

[0091] The technical solution of the embodiment of the present utility model, by setting an imaging unit and a light source device in the 3D modeling system, generates a modeling image through the cooperation of the imaging unit and the light source device, and controls the light source device to emit scanning lights of different bands according to the application scenario of the 3D modeling system, thereby improving the imaging effect and imaging quality of the 3D modeling system.

[0092] Optionally, continue to refer to Figure 7 As shown, the 3D modeling system further includes a rotating assembly 9;

[0093] The rotating assembly 9 is mechanically connected to the light source device 10;

[0094] The control unit 3 is electrically connected to the rotating assembly 9 and is used to control the rotation of the rotating assembly 9 according to the rotation signal so that the light source device 10 rotates.

[0095] Among them, the rotating assembly 9 can be used to change the light-emitting angle of the light source device 10. Since the object to be measured 8 in the real scene is a three-dimensional structure, the light source device 10 at a single angle is not sufficient to generate a modeling image. The rotating assembly 9 is set and mechanically connected to the light source device 10. The rotation of the rotating assembly 9 can drive the rotation of the light source device 10. The control unit 3 controls the rotating assembly 9 to rotate around the object to be measured 8, so that the imaging unit 7 can obtain scanning lights at different angles in real time, and the imaging unit 7 can further obtain the modeling image of the object to be measured 8 according to the scanning lights at different angles.

[0096] The technical solution of the embodiment of the present utility model, by setting a rotating assembly in the 3D modeling system, mechanically connecting the rotating assembly to the light source device, and controlling the rotation of the rotating assembly through the control unit so that the light source device rotates around the object to be measured, enabling scanning lights at different angles to be incident on the object to be measured, and the object to be measured reflects the scanning lights at different angles into the imaging unit, and the imaging unit generates a modeling image based on the scanning lights at different angles, ensuring the generation effect of the modeling image.

[0097] The above specific embodiments do not constitute a limitation to the protection scope of the present utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
