Referring to FIG1 and FIG2 , the phototherapy device 100 of the present embodiment includes a light source module 110, a base 120, and at least one light conversion component 130. The base 120 has a mounting groove 121. The light conversion component 130 can be detachably configured in the mounting groove 121. In addition, each light conversion component 130 includes a plurality of light conversion patterns 131. The light source module 110 is configured on one side of the base 120, and is suitable for providing an excitation light beam L1 to the light conversion pattern 131, and after the light conversion pattern 131 converts at least a portion of the excitation light beam L1 through excitation or the like, a conversion light beam L2 is emitted respectively. In FIG. 1 , the number of the light conversion components 130 is shown as one, but the light therapy device 100 of this embodiment may include a plurality of light conversion components 130. Since the light conversion components 130 can be detachably disposed in the mounting slot 121, the user of the light therapy device 100 can select a corresponding light conversion component 130 to be disposed in the mounting slot 121 according to different treatment courses or requirements.

In the present embodiment, the light source module 110 includes, for example, a plurality of light emitting elements 111 arranged in an array, but not limited thereto. In other embodiments, the light source module 110 may include at least one light emitting element 111, and is not limited by the number and arrangement. The light emitting element 111 may be a light emitting diode (LED), but not limited thereto. Each light emitting element 111 is suitable for providing a sub-beam La, and the above-mentioned excitation beam L1 includes these sub-beams La. The wavelength of the excitation beam L1 is, for example, between 430 and 460 nm, or other suitable wavelengths, depending on the matching light converter 130.

The above-mentioned base 120, for example, has a light incident surface 122, a light emitting surface 123 and a side surface 124. The light incident surface 122 is opposite to the light emitting surface 123, and the side surface 124 is connected between the light incident surface 122 and the light emitting surface 123. The light source module 110 is disposed on the light incident surface 122. The excitation light beam L1 from the light source module 110 is incident on the light conversion pattern 131 through the light incident surface 122, and the converted light beam L2 converted by the light conversion pattern 131 is emitted through the light emitting surface 123. The slot 121a of the mounting slot 121 is located on the side surface 124. The light conversion component 130 can be inserted into or pulled out of the mounting slot 121 through the slot 121a.

In this embodiment, the phototherapy device 100 may further include a protective layer 140, which is disposed between the base 120 and the light source module 110 to prevent the light source module 110 and the base 120 from being damaged. In addition, the material of the base 120 may be a flexible material or a non-flexible material. The phototherapy device 100 may be designed as a contact phototherapy device or a non-contact phototherapy device in different embodiments. In the embodiment in which the phototherapy device 100 is designed as a contact phototherapy device, the material of the base 120 is, for example, a flexible material, and the light source module 110 is also selected as a flexible light source module, the light conversion component 130 is also selected as a flexible light conversion component, and the protective layer 140 is also used in conjunction with a flexible protective layer. In addition, in the embodiment of the contact phototherapy device, the phototherapy device 100 may further include a skin-friendly layer 150, which is disposed on the surface of the base 120 away from the light source module 110 (i.e., the light-emitting surface 123) to enhance the user experience. The skin-friendly layer 150 is made of a light-transmissive material, which may be silicone, but is not limited thereto.

The above-mentioned light conversion element 130 includes, for example, a plurality of light conversion patterns 131. The material of each light conversion pattern 131 is, for example, a color conversion material such as quantum dots or fluorescent powder, but is not limited thereto. The light conversion element 130 further includes, for example, a light shielding layer 132, wherein the light shielding layer 132 separates a plurality of accommodation spaces S, and the above-mentioned light conversion patterns 131 are respectively arranged in the accommodation spaces S.

The luminous wavelengths of the light conversion patterns 131 of the light conversion element 130 (i.e., the wavelengths of the converted light beams L2) can be the same or different. Specifically, light of different wavelengths has different therapeutic effects, for example: red light has good penetrating power, helps activate blood circulation, relieve pain, and accelerate wound healing; green light helps relieve skin sensitivity symptoms and relieve fatigue; blue light helps treat acne, prevent wound infection, sterilize, and inhibit oil secretion; infrared light can stimulate muscle repair and relieve joint pain. Therefore, each light conversion element 130 may include a plurality of light conversion patterns 131 with different light emission wavelengths, such as a light conversion pattern 131a with a light emission wavelength of 500 nm to 540 nm (green light), a light conversion pattern 131b with a light emission wavelength of 610 nm to 650 nm (red light), and a light conversion pattern 131c with a light emission wavelength of 900 nm to 1250 nm (infrared light). In other embodiments, the light conversion pattern 131 of the light conversion element 130 may also have only one light emission wavelength, two light emission wavelengths, or more than three light emission wavelengths, depending on the design requirements.

In this embodiment, part of the accommodation space S is not provided with the above-mentioned light conversion pattern 131, so the excitation light beam L1 can pass through the light conversion element 130 and irradiate the user, so that light therapy can be performed by the excitation light beam L1 of the light source module 110. In one embodiment, the wavelength of the excitation light beam L1 is, for example, between 430 and 460 nm, so that the above-mentioned blue light therapeutic effect can be provided. In addition, in the accommodation space S without the light conversion pattern 131, for example, a through hole on the light conversion element 130 can be provided to allow the excitation light beam L1 to pass directly, or a transparent material that allows the excitation light beam L1 to pass through can be provided.

FIG3 is a schematic diagram of a light source module, a light conversion element, and a light spot projected on a reference surface of a phototherapy device of an embodiment of the present invention. Since in this embodiment, the structures of the phototherapy device 100 and the light conversion element 130 can refer to the aforementioned figures, they will not be described in detail here. Please refer to FIGS. 1 to 3. In FIG3, the light conversion element 130, for example, has two phototherapy patterns 133, and the phototherapy pattern 133 is formed by arranging a plurality of light conversion patterns 131 of FIG2. In addition, the light source module 110 can be designed to have a plurality of light-emitting blocks 112, and each light-emitting block 112 can include one or more light-emitting elements 111 shown in FIG1. In this way, by controlling the light-emitting block 112 corresponding to the phototherapy pattern 133 to emit light, the phototherapy pattern 133 can generate a light spot SP projected on the reference surface R. When the phototherapy device 100 performs phototherapy on a user, the reference surface R can be regarded as the user's skin surface. In another embodiment similar to FIG. 3 above, where two phototherapy patterns 133 are provided on the light conversion element 130, each light-emitting block 112 of the light source module 110 can be controlled to emit light, and the portion of the light conversion element 130 outside the two phototherapy patterns 133 does not have a light conversion pattern 131 or is provided with a light-shielding or light-absorbing material for shielding light.

FIG4 is a schematic diagram of another light conversion element in the embodiment of FIG3. Referring to FIG3 and FIG4, the number and shape of the phototherapy pattern 133a of the light conversion element 130a of FIG4 are different from the phototherapy pattern 133 of the light conversion element 130 of FIG3. In other words, the arrangement of the light conversion pattern 131 (as shown in FIG2) of different light conversion elements (such as light conversion elements 130, 130a) of the present invention can be different to form different phototherapy patterns 133, 133a. Therefore, the user can choose to replace the light conversion element (such as light conversion element 130 or light conversion element 130a) required for phototherapy according to different treatment courses or needs.

FIG5 is a block diagram of a phototherapy device according to an embodiment of the present invention. Since the structures of the light source module 110, the light converter 130, etc. can refer to the aforementioned figures, they will not be described in detail here. Please refer to FIG1, FIG3 and FIG5. The phototherapy device 100 of this embodiment may further include a control module 160, which is electrically connected to the light-emitting element 111 of the light source module 110, and the control module 160 is suitable for controlling the light intensity of the light-emitting element 111. The light intensity referred to here includes controlling whether the light-emitting element 111 emits light or not and controlling the brightness when emitting light. In this way, the above-mentioned control of the light-emitting block 112 corresponding to the phototherapy pattern 133 can be achieved.

1 and 5 , the phototherapy device 100 may further include a light sensor 170, which is, for example, disposed on the same side of the base 120 as the light source module 110. Specifically, the light sensor 170 may be disposed between the light emitting elements 111 as shown in FIG1 , or disposed beside the light source module 110. The light sensor 170 is, for example, electrically connected to the control module 160, and is adapted to sense the converted light beam L2 reflected back from the user. In this way, the user's skin condition, such as the wound condition, may be analyzed by the optical signal received by the light sensor 170, so as to facilitate subsequent treatment.

In addition, the phototherapy device 100 may further include a communication module 180 electrically connected to the control module 160. The communication module 180 can be used for information transmission between the phototherapy device 100 and an external device (e.g., a host of a medical unit). The transmitted information, for example, receives a control signal from the external device, transmits an optical signal received by the light sensor 170 to the external device, and transmits the usage time or other usage information of the phototherapy device 100 to the external device.

In summary, the phototherapy device of each embodiment of the present invention has a mounting slot on the base for detachably configuring the light conversion component. Therefore, when using the phototherapy device, the user can replace the corresponding light conversion component in a single phototherapy device according to different treatment courses or needs to convert the excitation light beam emitted by the light source module into the light wavelength and the required phototherapy pattern required for phototherapy.
