Description
Technical Field
[0001] This application belongs to the field of beauty equipment technology, specifically relating to a phototherapy array lamp. Background Technology
[0002] With the development of society, modern women have higher and higher pursuits of beauty, and various beauty and skin care technologies are constantly improving. Phototherapy is an advanced technology for skin care and treatment. This technology uses the dynamic reaction of light to convert light energy into intracellular energy, thereby accelerating cell growth, speeding up blood circulation, stimulating fibroblasts to produce collagen, and increasing skin elasticity.
[0003] LED lights, as a popular light source, have advantages such as low heat generation, no heat radiation, and safe touch, and are widely used in phototherapy research. Scientific experiments show that when cultured fibroblasts are irradiated with 590nm yellow LED light, their ATP production increases rapidly, thereby activating the metabolic activity of skin fibroblasts and producing a large amount of collagen fibers. Collagen fibers contain collagen, which has the effects of keeping skin moisturized, increasing skin density, shrinking pores, reducing wrinkles, and fading fine lines.
[0004] In existing beauty equipment, LED light sources have the following technical problems: First, direct or reflected light from LED light sources can easily enter the user's eyes, causing continuous glare and triggering discomfort such as dry eyes and eye fatigue; Second, the targeting of LED light fields is insufficient, causing most of the light energy to irradiate non-beauty areas, significantly weakening the phototherapy effect. Utility Model Content

Figure 3 A cross-sectional structural diagram showing the corresponding arrangement of the reflector cup and the light-emitting element is shown.
[0035] See Figure 1 As shown, this application embodiment provides a phototherapy array lamp 10, which can irradiate the user's area to be treated with light to achieve a phototherapy effect.
[0036] Among them, see Figure 1 As shown, the phototherapy array lamp 10 includes a housing body 100. The housing body 100 may have a hollow structure inside, and an opening is provided on one side of the housing body 100 (not shown in the figure). The overall shape of the housing body 100 may be rectangular, square, or circular, etc., and the specific shape may be selected according to different embodiments.
[0037] In some embodiments of this application, see Figure 2 and Figure 3 As shown, the housing body 100 may include a back plate 110 and a frame 120 connected to each other. Both the back plate 110 and the frame 120 may be made of plastic or metal. The back plate 110 may have a planar plate structure, and the frame 120 is disposed on one side surface of the back plate 110 and surrounds the outer edge of the back plate 110 to form a receiving groove (not shown in the figure) for storing devices.
[0038] In some embodiments of this application, see Figure 3 As shown, the back of the back plate 110 has anti-slip texture to improve the grip of the phototherapy lamp 10 and prevent the phototherapy lamp 10 from slipping.
[0039] In some embodiments of this application, please refer to... Figure 3As shown, the frame 120 includes a first frame 121 and a second frame 122. The first frame 121 is disposed vertically around the outer edge of the back panel 110 and extends away from the back panel 110. The second frame 122 is disposed on the side of the first frame 121 away from the back panel 110, and the second frame 122 is parallel to the back panel 110. An opening is provided in the center of the second frame 122, which allows a portion of the back panel 110 to be exposed.
[0040] In some embodiments of this application, see Figure 2 As shown, the phototherapy array lamp 10 also includes a light-emitting component 200. The light-emitting component 200 is disposed in the receiving groove formed by the back plate 110 and the frame 120.
[0041] In some embodiments of this application, see Figure 2 and Figure 3 As shown, the light-emitting component 200 includes a circuit board 210 and a plurality of light-emitting elements 220 spaced apart on the circuit board 210. The circuit board 210 can be a flexible circuit board 210, or other types of circuit boards 210, such as single-sided boards, double-sided boards, or rigid-flex boards. The light-emitting elements 220 can be LED beads, which can emit red, green, blue, white, or yellow light.
[0042] Understandably, LED beads of a single color, such as red, green, blue or yellow, can be arranged on the circuit board 210, or LED beads of different colors, such as red, green, blue and yellow.
[0043] In some embodiments of this application, see Figure 2 As shown, the circuit board 210 includes multiple light-emitting groups 220a arranged at intervals. Each light-emitting group 220a includes multiple light-emitting elements 220 arranged in an array, such as two light-emitting elements 220, three light-emitting elements 220, four light-emitting elements 220, six light-emitting elements 220, etc.
[0044] It should be noted that the array arrangement can be a rectangular array, a circular array, or an array of other shapes.
[0045] In some embodiments of this application, see Figure 2 As shown, each light-emitting group 220a includes four light-emitting elements 220 arranged in a rectangular array.
[0046] In one optional embodiment, the light-emitting elements 220 in each light-emitting group 220a have the same light-emitting color and wavelength, that is, all the light-emitting elements 220 on the entire circuit board 210 are LED beads of the same color and wavelength. The light-emitting elements 220 on the entire circuit board 210 are connected in series with each other and can be controlled to turn on and off according to the same pulse width modulation (PWM) signal.
[0047] In another optional embodiment, each light-emitting group 220a includes light-emitting elements 220 of the same color but different wavelengths. For example, each light-emitting group 220a includes two 620-650nm red light-emitting elements and two 640-680nm red light-emitting elements. Light-emitting elements 220 of different wavelengths within the same group and different wavelengths within different groups are connected in parallel, meaning that light-emitting elements 220 of different wavelengths are connected to different pulse width modulation (PWM) signals to control the on / off state of light-emitting elements 220 of different wavelengths, thereby achieving adjustable spectrum and brightness of the phototherapy lamp array 10. Light-emitting elements 220 of the same wavelength within the same group and different wavelengths within different groups are connected in series, allowing the same pulse width modulation (PWM) signal to control the simultaneous on / off state of the light-emitting elements 220.
[0048] In another optional embodiment, each light-emitting group 220a includes light-emitting elements 220 of different colors. For example, each light-emitting group 220a includes red, yellow, green, and blue light-emitting elements. The light-emitting elements 220 of each color in the same group are connected in parallel to achieve the effect of four-color light emission and mixed light emission of different colors. Moreover, each color light-emitting element 220 is individually controlled by a pulse width modulation (PWM) signal. Light-emitting elements 220 of the same color in different groups can be connected in series, and the same pulse width modulation (PWM) signal can be used to control the on and off of the light-emitting elements 220 of the same color in different groups.
[0049] In some embodiments of this application, the circuit board 210 can be detachably connected to the back plate 110. The detachable connection between the circuit board 210 and the back plate 110 can ensure the illumination stability of the light-emitting element 220 and the stability of the circuit board 210 in the receiving groove, avoiding damage caused by the circuit board 210 colliding with the back plate 110 due to shaking. It can also ensure the convenience of installing and removing the circuit board 210.
[0050] In one alternative example, both the circuit board 210 and the back plate 110 have threaded holes, and screws are threaded through the threaded holes of the circuit board 210 and the back plate 110 to make the circuit board 210 and the back plate 110 detachably connected.
[0051] In another alternative example, one of the circuit board 210 and the back plate 110 is provided with a snap-fit and the other is provided with a latch, the snap-fit being able to engage in the latch to connect the circuit board 210 to the back plate 110.
[0052] In another alternative example, the side of the circuit board 210 facing the back plate 110 and the side of the back plate 110 facing the circuit board 210 are both provided with adhesive layers, and the circuit board 210 and the back plate 110 are detachably connected by the adhesive layers.
[0053] In some embodiments of this application, see Figure 3 As shown, the phototherapy array lamp 10 also includes a cover plate 300 disposed at the opening. The cover plate 300 can have the same shape as the opening, such as a square or a circle. The cover plate 300 can be made of a transparent material so that the light emitted by the light-emitting element 220 can pass through the cover plate 300 and be emitted to the outside, thus avoiding the cover plate 300 from blocking the light of the light-emitting element 220.
[0054] For example, the cover plate 300 may be made of rigid transparent silicone, polycarbonate (PC), polymethyl methacrylate (PMMA), or other materials.
[0055] Understandably, the cover plate 300 is made of a rigid transparent material, which can ensure light transmission while also having a certain degree of rigidity, so as to prevent the cover plate 300 from being damaged and affecting the light output effect.
[0056] In some embodiments of this application, see Figure 3 As shown, the second frame 122 is provided with an annular groove (not shown in the figure), and the cover plate 300 is provided inside the annular groove, with the edge of the cover plate 300 fitting against the bottom of the annular groove.
[0057] The cover plate 300 can be connected to the second frame 122 by means of bonding, snap-fitting or screws.
[0058] For example, the side of the cover plate 300 facing the light-emitting element 220 can be bonded to the bottom wall of the annular groove using an adhesive such as UV-curable adhesive or epoxy resin adhesive to connect the cover plate 300 and the frame 120.
[0059] Figure 4 It shows Figure 3 Enlarged structural diagram of the cover plate at point A. Figure 5 A schematic diagram of the honeycomb lens surface and the Fresnel ring surface is shown. Figure 6 A schematic diagram of the honeycomb lens surface in the light-transmitting pattern area is shown. Figure 7 A schematic diagram of the Fresnel ring pattern surface in the light-transmitting pattern area is shown.
[0060] In some embodiments of this application, see Figure 4 and Figure 5As shown, the cover plate 300 has a honeycomb lens surface 310 and a Fresnel ring surface 320 formed on opposite sides. The honeycomb lens surface 310 is located on the Fresnel ring surface 320 near the light-emitting element 220, meaning that the light emitted by the light-emitting element 220 first passes through the honeycomb lens surface 310 and then exits through the Fresnel ring surface 320.
[0061] In other embodiments of this application, two glass substrates (not shown in the figure) may be integrated and stacked on the same side surface of the cover plate 300. One glass substrate has a honeycomb lens surface 310 on its surface, and the other glass substrate has a Fresnel ring surface 320 on its surface. The two glass substrates can be bonded together with adhesive, either with the side of the glass substrate without the honeycomb lens surface 310 and the side without the Fresnel ring surface 320. As long as the honeycomb lens surface 310 is located on the side of the Fresnel ring surface 320 closer to the light-emitting element 220, the light emitted by the light-emitting element 220 first passes through the honeycomb lens surface 310 and then exits through the Fresnel ring surface 320.
[0062] In some embodiments of this application, in the light emission direction, a glass substrate is provided on one side of the cover plate 300, and a honeycomb lens surface 310 and a Fresnel ring surface 320 are formed on opposite sides of the glass substrate. The honeycomb lens surface 310 is located on the side of the Fresnel ring surface 320 that is closer to the light-emitting element 220.
[0063] Among them, see Figure 5 and Figure 6 As shown, the honeycomb lens surface 310 includes a plurality of interconnected polygonal (hexagonal) protrusion units 311. These protrusion units 311 protrude towards one side of the Fresnel ring surface 320 to improve light mixing uniformity and reduce discomfort caused by direct light from the light-emitting element 220 into the user's eyes. See also... Figure 7 As shown, the Fresnel ring surface 320 can enhance the light-gathering effect, so that the emitted beauty light is concentrated on the user's skin.
[0064] Understandably, the cosmetic light rays pass through the honeycomb lens surface 310, which diffuses and mixes the cosmetic light rays emitted by the light-emitting component 200, making the energy distribution of the cosmetic light rays more uniform, avoiding strong light directly hitting the user's eyes, effectively reducing the discomfort caused by glare, and the diffused light can cover a wider area. After being homogenized by the honeycomb lens surface 310, the cosmetic light rays enter the Fresnel ring surface 320 for reorientation, focusing the diffused cosmetic light rays to ensure that the energy is concentrated on the area to be treated, thereby improving the efficiency of phototherapy.
[0065] It should be noted that the honeycomb lens surface 310 and the Fresnel annular surface 320 are formed on the opposite sides of the cover plate 300 in the following ways: either the honeycomb lens surface 310 and the Fresnel annular surface 320 are formed directly on the opposite sides of the cover plate 300 using specific precision processing technology; or the honeycomb lens surface 310 and the Fresnel annular surface 320 are respectively set on two glass substrates and then fixed to the opposite sides of the cover plate 300 by bonding.
[0066] The honeycomb lens surface 310 can be formed on the side of the cover plate 300 facing the light-emitting element 220 by injection molding or ultraviolet embossing. The Fresnel ring surface 320 can be formed on the side of the cover plate 300 away from the light-emitting element 220 by mold (compression molding, glass thermoforming) or direct processing (femtosecond laser micromachining, electron beam lithography).
[0067] In some embodiments of this application, see Figure 3 As shown, the phototherapy array lamp 10 also includes a reflector cup 400 that is open at both ends and hollow inside. The reflector cup 400 is located inside the housing body 100, that is, in the receiving groove formed by the back plate 110 and the frame 120.
[0068] In some embodiments of this application, please refer to... Figure 2 and Figure 3 As shown, the reflector cup 400 can be set one-to-one with the light-emitting element 220. The inner surface of the reflector cup 400 has a reflective surface for reflecting light (not shown in the figure). The beauty light emitted by the light-emitting element 220 can be concentrated on the cover plate 300 through the reflective surface inside the reflector cup 400, thereby improving the light utilization rate, light efficiency and controlling the distribution of beauty light.
[0069] In other embodiments of this application, a group of light-emitting elements 220a can correspond to a reflector 400, that is, multiple light-emitting elements 220 correspond to a reflector 400, as long as the beauty light can be concentrated and directed toward the cover plate 300.
[0070] Please refer to some embodiments of this application. Figure 3 As shown, in the direction of the circuit board 210 near the cover plate 300, the cross-sectional area of the reflector cup 400 gradually increases, that is, the reflector cup 400 has a gradually expanding structure, which can achieve wider beam diffusion and higher uniformity.
[0071] In some embodiments of this application, please refer to... Figure 3As shown, the phototherapy array lamp 10 also includes a reflector 500 made of transparent material. The reflector 500 is connected to the side of the reflector cup 400 away from the light-emitting element 220, integrating the reflector cup 400 for centralized management. This makes installing and removing the reflector cup 400 from the light-emitting element 220 more convenient and reduces installation costs. The reflector cup 400 and reflector 500 can be integrally formed, or the reflector cup 400 can be fixed to the reflector plate 500 by welding or other methods.
[0072] In some embodiments of this application, both the reflector 500 and the back plate 110 are provided with threaded holes, and screws are provided through the threaded holes. The reflector 500 is detachably connected to the back plate 110 by screws, so as to fix the reflector 500 in the receiving groove, and also facilitate the installation and replacement of the reflector 500.
[0073] In some other embodiments of this application, one of the reflector 500 and the back plate 110 is provided with a buckle, and the other is provided with a corresponding latch. The reflector 500 and the back plate 110 are detachably connected by the buckle to fix the reflector 500 in the receiving groove, and also to facilitate the installation and replacement of the reflector 500.
[0074] Please refer to some embodiments of this application. Figure 1 , Figure 6 and Figure 7 As shown, the cover plate 300 has a light-transmitting pattern area 330 corresponding to the light-emitting group 220a. A honeycomb lens surface 310 and a Fresnel ring surface 320 are formed on opposite sides of the light-transmitting pattern area 330, respectively. By providing the honeycomb lens surface 310 and the Fresnel ring surface 320 within the light-transmitting pattern area 330, the manufacturing area of the honeycomb lens surface 310 and the Fresnel ring surface 320 can be reduced, thereby reducing the manufacturing cost of the honeycomb lens surface 310 and the Fresnel ring surface 320.
[0075] It should be noted that in some embodiments, the honeycomb lens surface 310 and the Fresnel annular surface 320 can also be designed as a whole surface, that is, the honeycomb lens surface 310 and the Fresnel annular surface 320 are provided on both opposite sides of the cover plate 300.
[0076] In some embodiments of this application, the phototherapy lamp array 10 includes multiple spaced reflector groups (not shown in the figure), each reflector group corresponding to a light-emitting group 220a, and each reflector group includes multiple (four) reflector cups 400, which are arranged in an array on the reflector plate 500, and each reflector cup 400 corresponds to a light-emitting element 220.
[0077] Please refer to some embodiments of this application. Figure 1As shown, the light-transmitting pattern area 330 at least completely covers the reflector group. For example, the coverage area of the light-transmitting pattern area 330 is larger than the area of the reflector group to ensure that the light reflected from the reflector group is emitted after being processed by the honeycomb lens surface 310 and the Fresnel ring surface 320, thereby improving the light efficiency of the cosmetic light and thus improving the skin irradiation effect of the phototherapy lamp array 10.
[0078] Please refer to some embodiments of this application. Figure 1 As shown, the light-transmitting pattern area 330 includes four sets of equiangularly distributed elliptical units (not shown in the figure). The light-transmitting pattern area 330 presents a closed planar contour with fourfold rotational symmetry and is composed of a radial array of four sets of elliptical units around its central point. These elliptical units can completely cover the light reflected by a single reflector cup 400, ensuring that the light passing through the reflector cup 400 can be emitted after being processed by the honeycomb lens surface 310 and the Fresnel ring surface 320, thus guaranteeing the cosmetic lighting effect.
[0079] Please refer to some embodiments of this application. Figure 1 As shown, the phototherapy lamp array 10 also includes a button 600 exposed on the cover plate 300. When the button 600 is pressed, the conductive contacts on the circuit board 210 are turned on, and the circuit board 210 outputs a pulse width modulation (PWM) signal to control the light emission state of the light-emitting element 220, thereby regulating the working mode of the phototherapy lamp array 10. For example: power button 600 (turns on the light-emitting element 220), continuous illumination button 600, screen flash button 600, brightness increase or decrease button 600, etc.
[0080] Please refer to some embodiments of this application. Figure 2 As shown, the phototherapy lamp 10 also includes a sound signal receiver 700, which is located inside the housing 100 and electrically connected to the circuit board 210. The sound signal receiver 700 can convert sound signals into electrical signals and transmit the converted electrical signals to the circuit board 210. The electrical signals are modulated by the circuit board 210 to output a pulse width modulation (PWM) signal for controlling the light-emitting state of the light-emitting element 220. That is, the working mode of the phototherapy lamp 10 can be controlled by voice through the sound signal receiver 700.
[0081] In some embodiments of this application, please refer to... Figure 2 As shown, the phototherapy lamp array 10 also includes a sound signal output device 800. The sound signal output device 800 is located inside the housing body 100 and is electrically connected to the circuit board 210. The sound signal output device 800 can convert the electrical signal transmitted by the circuit board 210 into a sound signal so that the working mode of the phototherapy lamp array 10 can be transmitted through the sound signal, so that the working mode of the phototherapy lamp array 10 can be understood more clearly.
[0082] Please refer to some embodiments of this application. Figure 1 As shown, the phototherapy array lamp 10 also includes a display screen 900 disposed on a cover plate 300. The cover plate 300 has a through hole for exposing the display screen 900. The display screen 900 passes through the cover plate 300 and is electrically connected to the circuit board 210 to display the operating mode of the light-emitting element 220, allowing for a more intuitive and clear understanding of the operating mode of the phototherapy array lamp 10.
[0083] It should be noted that the phototherapy light array 10 can be powered by an external power source and stored by a built-in battery (not shown in the figure) with a dual power supply architecture.
[0084] Please refer to some embodiments of this application. Figure 2 As shown, the phototherapy array lamp 10 also includes an electrical connection socket 1000. The electrical connection socket 1000 is located on the outer wall of the housing body 100, and it can be connected to an external power source such as an adapter or a power bank. When the socket is connected to an external power source, the power is preferentially delivered directly to the circuit board 210 to ensure that the light-emitting element 220 works immediately and reduce the dependence on the built-in battery.
[0085] When the external power supply is sufficient, redundant power charges the built-in battery through a bidirectional DC / DC converter. When the external power supply is insufficient, it switches to a hybrid power supply mode, where the external power supply and the battery work together to prevent the phototherapy lamp array 10 from throttling due to insufficient input power.
[0086] When the electrical connection port 1000 is connected to an external power source, the phototherapy LED array 10 is powered directly from the external source by default, with the battery serving only as a backup energy storage unit. This design reduces the number of battery cycles and extends its lifespan. If the external power supply is suddenly disconnected, it switches to battery power to ensure uninterrupted operation of the phototherapy program and avoid sudden changes in LED brightness.
