[0035] See Figures 1 to 3 This embodiment provides a beauty light panel that uses a VCSEL chip 5 (Vertical-Cavity Surface-Emitting Laser) as a light source to enhance the beauty and skincare effects of the beauty light panel. The specific solution is described in the following embodiment.
[0036] The beauty light array in this embodiment includes a housing, a circuit board 4, a light source module, and a middle cover plate 7. One side of the housing has a light-emitting surface 100, which can be transparent to allow light to pass through. The housing can be square or round. In use, the light-emitting surface 100 faces the area to be treated, such as the face, hands, or back. As a light array, the light-emitting surface 100 of the housing is planar.
[0037] In some embodiments, the housing has a hollow cavity inside for accommodating other components of the beauty light array. A circuit board 4 is disposed within the housing; the circuit board 4 has a plate-like structure and is positioned opposite the light-emitting surface 100.
[0038] In some embodiments, the light source module includes a plurality of VCSEL chips 5 spaced apart on a circuit board 4. The VCSEL chips 5 are disposed on the side of the circuit board 4 facing the light-emitting surface 100, and are electrically connected to the circuit board 4 to power and control the emission of lasers from the VCSEL chips 5. The laser emitted by the VCSEL chips 5 passes through the light-emitting surface 100 and is directed toward the area to be treated. The VCSEL chips 5 have advantages such as low power consumption, low heat generation, and small divergence angle.
[0039] In some embodiments, light-emitting dots 50 are formed on the surface of the VCSEL chip 5, and the laser emitted by the VCSEL chip 5 is emitted through the light-emitting dots 50. In this embodiment, a plurality of light-emitting dots 50 are formed on the surface of the VCSEL chip 5 at intervals, and the laser emitted by the plurality of light-emitting dots 50 of the VCSEL chip 5 forms a laser beam, which is emitted through the light-emitting surface 100 to the area to be treated.
[0040] In some embodiments, the middle cover plate 7 is disposed inside the housing and is located between the light-emitting surface 100 and the circuit board 4. A plurality of first mounting areas are formed on the middle cover plate 7, and the plurality of first mounting areas are arranged in a one-to-one correspondence with a plurality of VCSEL chips 5. Each first mounting area is provided with a first optical element, which is used to perform optical processing on the laser emitted by the VCSEL chip 5 to make its emission more uniform.
[0041] In some embodiments, the housing may include a front cover 10 and a back cover 11. The back cover 11 forms an open cavity at one end, and the front cover 10 covers the open cavity of the back cover 11 to close the open cavity and form a cavity, facilitating the disassembly of the housing to accommodate the middle cover 7 and the circuit board 4. The front cover 10 may be a transparent plate to form a light-emitting surface 100.
[0042] In this embodiment, the laser beams emitted by multiple light-emitting points 50 of the VCSEL chip 5 form dense phototherapy points for beauty and skin care. When used in a beauty panel light, it has lower energy loss and generates less heat at the same power, resulting in a milder burning sensation on the skin and better skin penetration, thus effectively improving the beauty and skin care effect of the beauty panel light.
[0043] In some embodiments, the VCSEL chip 5 can be a back-emitting structure or a bottom-emitting structure, and the laser emitted by it is emitted from the substrate side of the VCSEL chip 5. The substrate material can be gallium arsenide, and an anti-reflection film can be disposed on the substrate to improve laser quality and reduce light loss.
[0044] In some embodiments, the multiple light-emitting points 50 formed on the VCSEL chip 5 can be a regularly arranged matrix distribution or a random distribution, such as rings, waves, triangles, etc.
[0045] In some embodiments, the multiple VCSEL chips 5 can be VCSEL chips of different models 5, which can generate lasers of different wavelengths. Alternatively, the multiple VCSEL chips 5 can be VCSEL chips of the same model 5, generating lasers of the same wavelength. For example, the laser wavelength range can be 780nm-1550nm. To achieve laser hair removal, an 808nm wavelength VCSEL chip 5 can be used; to achieve laser skin rejuvenation, a 1064nm wavelength VCSEL chip 5 can be used, and so on.
[0046] In some embodiments, the light source module further includes a plurality of LED light-emitting chips 6 spaced apart on the circuit board 4. The LED light-emitting chips 6 are disposed on the side of the circuit board 4 facing the light-emitting surface 100, and the plurality of LED light-emitting chips 6 and the plurality of VCSEL chips 5 are arranged at intervals. By setting the LED light-emitting chips 6, the light emitted by the LED light-emitting chips 6 and the laser emitted by the VCSEL chips 5 can be emitted simultaneously to act on the area to be treated, or they can be emitted independently as needed, thereby improving the application range of the beauty light panel.
[0047] In some embodiments, a plurality of second mounting areas are formed on the middle cover plate 7, and the plurality of second mounting areas are arranged in a one-to-one correspondence with a plurality of LED light-emitting chips 6. Each second mounting area is provided with a second optical element 71, which is used to enhance the brightness of light emitted after it passes through it. The light emitted by the LED light-emitting chip 6 is optically processed by the second optical element 71 and then emitted from the light-emitting surface 100.
[0048] In some embodiments, the first mounting area and the second mounting area can be grooves formed on the middle cover plate 7, with the first optical element and the second optical element 71 disposed in the corresponding grooves for fixed installation. Alternatively, the first mounting area and the second mounting area can be through holes formed on the middle cover plate 7, with the first optical element and the second optical element 71 disposed in the corresponding through holes.
[0049] In some embodiments, the first optical element includes one or more of a reflector and a light-diffusing microstructure. The first optical element can be a reflector or a light-diffusing microstructure. The light-diffusing microstructure, through its surface or internal micro-geometry, scatters, refracts, or reflects incident laser light, thereby achieving greater uniformity of the laser beam after passing through the first optical element. It can be a microlens array, a prism structure, or a micropore structure. When the first optical element is a reflector, the relative positions of the cover plate 7 and the circuit board 4 can be set so that the VCSEL chip 5 is located at the focal point of the reflector.
[0050] In some embodiments, the second optical element 71 includes one or more of a reflector and an optical lens. The second optical element 71 can be a reflector or an optical lens, thereby making the light emitted from the second optical element 71 more uniform and improving brightness and light intensity.
[0051] In some embodiments, multiple LED light-emitting chips 6 are arranged in a rectangular array, forming several columns and rows, with multiple VCSEL chips 5 interspersed among the LED light-emitting chips 6. Specifically, VCSEL chips 5 can be placed between adjacent LED light-emitting chips 6 in each row, between adjacent LED light-emitting chips 6 in each column, or in areas between adjacent rows or columns of LED light-emitting chips 6; the arrangement is flexible and can be determined according to actual needs. The luminous power of the VCSEL chip 5 can be lower than or equal to the luminous power of the adjacent LED light-emitting chips 6.
[0052] In some embodiments, the circuit board 4 may also have a first region and a second region separated from each other. The first region and the second region may be separated along the length direction of the circuit board 4 or along the width direction of the circuit board 4. The area ratio of the first region and the second region may be 1:1 or not 1:1. Multiple LED light-emitting chips 6 are disposed in the first region, and multiple VCSEL chips 5 are disposed in the second region, so that the LED light-emitting chips 6 and VCSEL chips 5 are separated, which facilitates the simultaneous irradiation of different areas of the area to be treated with different light types, and improves the diversity of irradiation modes.
[0053] In some embodiments, the LED light-emitting chip 6 includes one or more of a red light chip 60, a green light chip 61, a blue light chip 62, and a yellow light chip 63. The red light chip 60 emits red light of a corresponding wavelength, such as 660nm, which can improve skin tone evenness. The blue light chip 62 emits blue light of a corresponding wavelength, such as 415nm, which can regulate sebum secretion. The yellow light chip 63 emits yellow light of a corresponding wavelength, such as 590nm, which can inhibit melanin formation. The green light chip 61 emits green light of a corresponding wavelength, such as 560nm, which balances skin pigmentation and improves uneven skin tone. Of course, the wavelengths of each light source can also be other specific wavelengths, which will not be elaborated upon here.
[0054] In some embodiments, the LED light-emitting chip 6 may include only a red light chip 60, or only a green light chip 61, or a blue light chip 62, or a yellow light chip 63, depending on the functional requirements.
[0055] See Figure 3 In this embodiment, when the LED light-emitting chip 6 includes a red light chip 60, a green light chip 61, a blue light chip 62, and a yellow light chip 63, the red light chip 60, green light chip 61, blue light chip 62, and yellow light chip 63 are combined to form a light-emitting unit. The four form an RGBY combined light source. The red light chip 60, green light chip 61, blue light chip 62, and yellow light chip 63 in the light-emitting unit are arranged in a rectangular distribution. Multiple light-emitting units are arranged in a rectangular array on the circuit board 4. In two adjacent light-emitting units in the same row or column, the first light-emitting unit rotates around its center as a rotation axis, rotates by a preset angle in a preset rotation direction, and then translates by a preset distance to coincide with the second light-emitting unit. By adjusting the placement direction of the red light chip 60, green light chip 61, blue light chip 62, and yellow light chip 63 in the light-emitting units at different positions, more uniform light mixing can be ensured.
[0056] In some embodiments, the preset rotation direction can be clockwise or counterclockwise. The preset angle can be any suitable angle, such as 45°, 60°, 90°, 135° or 180°, etc. The smaller the preset angle, the finer the light mixing and the better the effect.
[0057] In some embodiments, the preset rotation direction of each row of light-emitting units is the same, and the preset rotation direction of each column of light-emitting units is the same. In this embodiment, the preset rotation direction of each row of light-emitting units is clockwise, and the preset rotation direction of each column of light-emitting units is clockwise, with a preset angle of 90°. By arranging the light-emitting units in this way, the color temperature accuracy can be improved at different viewing angles after light mixing, and the color cast problem can be greatly reduced.
[0058] See Figure 1 and Figure 2 In this embodiment, the housing consists of three parts: a first housing 1, a second housing 2, and a third housing 3. The second housing 2 and the third housing 3 are hinged to opposite sides of the first housing 1, allowing them to rotate around the first housing 1 to form various configurations. For example, when the second housing 2 and the third housing 3 rotate to be flush with the first housing 1, the beauty light panel is roughly flat, with the light-emitting surface 100 in the same direction being the largest. Alternatively, the second housing 2 and the third housing 3 can rotate towards each other, forming a 90° angle with the first housing 1, making the beauty light panel roughly "U"-shaped. This allows a hand to be inserted into the panel, with the light-emitting surface 100 of the beauty light panel surrounding the hand.
[0059] It is understood that the first housing 1, the second housing 2, and the third housing 3 have the same function, each having a light-emitting surface 100, and each containing a circuit board 4 and a middle cover plate 7. The circuit boards 4 inside the first housing 1, the second housing 2, and the third housing 3 are all equipped with light source modules, enabling each housing 1, the second housing 2, and the third housing 3 to emit light or laser light outwards through their light-emitting surfaces 100. The first housing 1 forms the main light, while the second housing 2 and the third housing 3 form side lights. The light-emitting surfaces 100 of the first housing 1, the second housing 2, and the third housing 3 are located on the same side, such as their front side, so that when the three are rotated to be aligned, their light-emitting surfaces 100 can simultaneously face the area to be treated.
[0060] In some embodiments, a pivot assembly 12 may be provided on opposite sides of the first housing 1, and a pivot hole may be provided on the side of the second housing 2 and the third housing 3 that is hinged to the first housing 1, so that the pivot assembly 12 is rotatably connected in the pivot hole, thereby enabling the second housing 2 and the third housing 3 to rotate relative to the first housing 1.
[0061] In some embodiments, regarding the distribution of LED light-emitting chips 6 and VCSEL chips 5, multiple LED light-emitting chips 6 are disposed on a circuit board 4 located inside the first housing 1, and multiple VCSEL chips 5 are disposed on a circuit board 4 located in the second housing 2 or the third housing 3. The LED light-emitting chips 6 serve as the main light source, and the VCSEL chips 5 serve as the secondary light source, irradiating different areas of the area to be treated to different degrees, thereby improving flexibility.
[0062] In some embodiments, the beauty light panel also includes a TOF (Time-of-Flight) sensor disposed on a circuit board 4. The TOF sensor is connected to at least one VCSEL chip 5 to measure the distance between the beauty light panel and the area to be treated. The circuit board 4 controls the working state of the light source module, such as on or off, based on the measured distance value, and can also adjust the luminous power according to the distance value. The TOF sensor has the characteristics of high accuracy and fast distance measurement. When used in conjunction with the VCSEL chip 5, the VCSEL chip 5 acts as a laser source to emit laser pulses, and the TOF sensor measures the time delay between the emitted laser pulse and the laser pulse reflected back from the area to be treated. This time delay is converted into a distance value.
[0063] If the measured distance is greater than the preset value, it means that the beauty light panel is too far from the area to be treated, and the light source module can be turned off. If the measured distance is less than or equal to the preset value, the light source module can be turned on, and the light output power of the light source module can be further controlled. The closer the distance, the lower the power, and the farther the distance, the higher the power, so as to realize the automatic control of the light source module and improve safety.
[0064] In some embodiments, the TOF sensor can also be connected to all VCSEL chips 5 and paired with a data processing module to output 3D data of the target object (such as a human face) based on the data output by the TOF sensor. The circuit board 4 controls the automatic adjustment of the beauty mode based on the output 3D data. For example, if the irradiation area is identified as the whole face, the full face skin beautification mode is automatically called. If it is identified as the hand, the hand beautification mode is activated.
[0065] In some embodiments, the beauty panel light also includes a support member 8. The support member 8 is hinged to the side of the first housing 1 facing away from its light-emitting surface 100. The support member 8 can rotate relative to the first housing 1 between a first position and a second position. When the support member 8 rotates to the first position, the end of the support member 8 facing away from the first housing 1 abuts against the external support surface to support the first housing 1. When the support member 8 rotates to the second position, the first support member 8 is attached to the side of the first housing 1 facing away from its light-emitting surface 100, thereby folding the support member 8 onto the first housing 1 for easy storage of the beauty panel light.
[0066] When the support member 8 is in the first position, a certain angle is formed between the support member 8 and the first housing 1. The beauty light relies on the bottom end of the first housing 1 and the end of the support member 8 away from the first housing 1 to abut against the external support surface to form two-point support, thereby supporting the beauty light on the external support surface. The external support surface can be the ground or a table, etc.
[0067] In some embodiments, the support member 8 can be a plate-like structure, which can fit tightly against the first housing 1 when rotated to the second position, making the beauty light panel smaller in size. At the same time, when rotated to the first position, the contact area with the external support surface is larger, and the support is more stable.
[0068] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
