Description

Technical Field

[0001] This utility model relates to a lighting device, and more particularly to a beauty lamp. Background Technology

[0002] As people's living standards continue to improve, their demand for skin care is also increasing. There are various methods of skin care, such as phototherapy, in which visible light is widely used to treat photoaging, inflammation, wound healing, sunburn, acne, and many other conditions. Currently, some beauty lamps on the market also emit visible light for phototherapy; however, these lamps have limited functionality and are suitable for relatively simple applications. Therefore, there is an urgent need for a more versatile beauty lamp. Utility Model Content

[0003] The purpose of this utility model is to provide a beauty lamp to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this utility model is:

[0005] A beauty lamp includes: a phototherapy module comprising a semi-transparent and semi-reflective layer, a first light guide layer, an electrochromic layer, and a light-absorbing layer arranged sequentially from back to front, wherein a plurality of first lamp bodies are arranged around the outer side of the first light guide layer, and the plurality of first lamp bodies emit light into the first light guide layer; and an illumination module located beside the phototherapy module, the illumination module comprising a diffusion layer and a second light guide layer arranged sequentially from back to front, wherein a second lamp body is arranged outside the second light guide layer, and the second lamp body emits light into the second light guide layer.

[0006] This technical solution has at least the following beneficial effects: Depending on the usage needs, the beauty lamp can switch between phototherapy and mirror functions. Specifically, when the phototherapy function is needed, the second lamp is off, the first lamp is on, and the electrochromic layer is energized. When energized, the electrochromic layer becomes a mist layer or a white layer, allowing light to pass through in small amounts or making it opaque. The second lamp emits light into the first light guide layer. Some light directly exits from the first light guide layer to the semi-transparent and semi-reflective layer, then shines outwards. Other light enters the electrochromic layer and is scattered or reflected, re-entering the first light guide layer before shining outwards, irradiating the human skin for phototherapy. When the mirror function is needed, the first lamp is off and the second lamp is on. At this time, the electrochromic layer is not energized and is transparent, allowing light to pass through. When external light shines on the semi-transparent and semi-reflective layer, some of the light is reflected by the semi-transparent and semi-reflective layer, forming a clear image on its surface, thus realizing the mirror function. The rest passes through the semi-transparent and semi-reflective layer, the nano light guide plate, and the electrochromic layer, and finally reaches the light-absorbing layer and is absorbed, effectively reducing stray light from affecting the clarity of the image. In this way, the phototherapy beauty function or the mirror function can be switched according to the needs of use, enriching the overall functionality, making it suitable for more usage scenarios, and improving overall practicality.

[0007] As a further improvement to the above technical solution, the first light guide layer is a nano-light guide plate. When the first lamp emits light towards the nano-light guide plate from the side, the nanoparticles inside the nano-light guide plate scatter the light, which can improve the efficiency of light scattering. More light can be emitted directly from the nano-light guide plate to the semi-transparent and semi-reflective layer. Furthermore, the nano-light guide plate is transparent, which reduces the impact when the whole system is switched to use as a mirror.

[0008] As a further improvement to the above technical solution, the light-absorbing layer is made of black velvet. Black itself has good absorption of visible light, and the surface of the velvet itself is rough and porous. This structure can increase the multiple reflections of light on the fabric surface. Each time light is reflected inside the fabric, a certain proportion of the light is absorbed. After multiple reflections, the light is almost completely absorbed, which greatly improves the light absorption effect of the light-absorbing layer and further improves the image clarity when the whole is used as a mirror.

[0009] As a further improvement to the above technical solution, the diffusion layer is an annular plate, the semi-transparent and semi-reflective layer is located within the diffusion layer, the second light guide layer extends around the diffusion layer, and the second lamp body is located at the end of the second light guide layer. When the whole unit is used as a mirror, the annular diffusion layer is arranged outside the beauty module used as a mirror. The second lamp body emits light into the second light guide layer, which guides the light. After the light passes through the diffusion layer to even out the light, it is emitted outward, thus forming uniform light around the outside of the mirror and improving the user experience.

[0010] As a further improvement to the above technical solution, a second lamp body is provided at both ends of the second light guide layer. When the lighting module is working, the two second lamp bodies provide illumination from both ends of the second light guide layer, thereby guiding the light from both ends of the second light guide layer to the middle of the second light guide layer, increasing the brightness, and thus improving the lighting function when used as a mirror.

[0011] As a further improvement to the above technical solution, the second light guide layer is located behind the first lamp body, and the inner annular portion of the diffusion layer abuts against the rear side of the semi-transparent and semi-reflective layer. The lighting module and the phototherapy module are arranged along the front-to-back direction, and the abutment of the inner annular portion of the diffusion layer against the rear side of the semi-transparent and semi-reflective layer makes the overall connection structure more compact.

[0012] As a further improvement to the above technical solution, the outer ring of the diffusion layer extends backward at an angle. This angled arrangement of the diffusion layer allows it to enclose a gradually expanding area, facilitating connection with external structures such as lamp housings, improving the overall appearance. Furthermore, an area for installing a second light guide layer can be formed in front of the diffusion layer, resulting in a tighter overall connection.

[0013] As a further improvement to the above technical solution, an air gap is formed between the inner annular portion of the diffusion layer and the semi-transparent and semi-reflective layer. This air gap allows for the installation of external structural components, such as control keys, and functions can be switched using the control keys within the air gap.

[0014] As a further improvement to the above technical solution, the ratio of reflectivity to transmittance of the semi-transparent and semi-reflective layer is 1. When the system is switched to the phototherapy function, light passing through the first light guide layer can be transmitted outward through the semi-transparent and semi-reflective layer, at which point the transmittance of the semi-transparent and semi-reflective layer is mainly reflected. When the system is switched to the mirror function, external light is reflected outward through the semi-transparent and semi-reflective layer, at which point the reflectivity of the semi-transparent and semi-reflective layer is mainly reflected. Within this ratio range, the light transmission and reflection functions of the semi-transparent and semi-reflective layer can be balanced.

[0015] As a further improvement to the above technical solution, both the first lamp body and the second lamp body are adjustable spectrum lamps. Adjustable spectrum lamps can simulate and adjust light of different wavelengths to meet people's functional needs for phototherapy and lighting, and improve the flexibility of use.

[0025] Reference Figure 1 , Figure 2 and Figure 3 A beauty lamp includes a phototherapy module and an illumination module. The phototherapy module includes a semi-transparent and semi-reflective layer 110, a first light guide layer 120, an electrochromic layer 130, and a light-absorbing layer 140 arranged sequentially from back to front. A plurality of first lamp bodies 150 are arranged around the outer side of the first light guide layer 120, and the plurality of first lamp bodies 150 emit light into the first light guide layer 120. The illumination module is located next to the phototherapy module. The illumination module includes a diffusion layer 210 and a second light guide layer 220 arranged sequentially from back to front. A second lamp body 230 is arranged on the outer side of the second light guide layer 220, and the second lamp body 230 emits light into the second light guide layer 220.

[0026] As described above, depending on the usage needs, the beauty lamp can be switched between phototherapy beauty function and mirror function. Specifically, when the phototherapy beauty function is needed, the second lamp body 230 is in the off state, the first lamp body 150 is in the on state, and the electrochromic layer 130 is energized. When the electrochromic layer 130 is energized, it becomes a mist layer or a white layer. At this time, light can pass through in small amounts or not at all. The second lamp body 230 emits light to the first light guide layer 120. Some light is directly emitted from the first light guide layer 120 to the semi-transparent and semi-reflective layer 110, and then emitted outwards. Some light enters the electrochromic layer 130 and is scattered or reflected, then re-enters the first light guide layer 120, and then emits outwards, irradiating the human skin for phototherapy beauty. When the second lamp body 230 is needed, the second lamp body 230 is in the off state, the first lamp body 150 is in the on state, and the first lamp body 150 is energized, energizing the human skin for phototherapy beauty. When using the mirror function, the first lamp body 150 is in the off state and the second lamp body 230 is in the on state. At this time, the electrochromic layer 130 is not energized. When the electrochromic layer 130 is not energized, it is transparent and light can pass through. When external light shines on the semi-transparent and semi-reflective layer 110, some of the light is reflected by the semi-transparent and semi-reflective layer 110, forming a clear image on its surface, thus realizing the mirror function. The other part passes through the semi-transparent and semi-reflective layer 110, the nano light guide plate, and the electrochromic layer 130, and finally reaches the light-absorbing layer 140 and is absorbed, effectively reducing stray light from affecting the clarity of the image. In this way, the phototherapy beauty function or the mirror function can be switched according to the needs of use, enriching the overall functions and making it suitable for more usage scenarios, thus improving the overall practicality.

[0027] The first light guide layer 120 primarily scatters light entering from the side of the first lamp body 150, directing it to be emitted from the front. Its structure can take various forms. For example, printing ink or adding scales to the bottom of the first light guide layer 120 would make it not completely transparent, thus affecting the mirror's performance. Another type is a first light guide layer 120 without printing ink or adding scales to the bottom. In this case, most light entering the light guide plate meets the total internal reflection condition, so only a very small amount of light can escape from the surface of the first light guide layer 120. Although this type of first light guide layer 120 is completely transparent, its efficiency is extremely low. In this embodiment, the first light guide layer 120 is a nano-light guide plate. When the first lamp body 150 emits light towards the nano-light guide plate from its side, the nanoparticles inside the nano-light guide plate scatter the light, improving the efficiency of light scattering. More light can directly exit from the nano-light guide plate to the semi-transparent, semi-reflective layer 110, and the nano-light guide plate is transparent. As for the second light guide layer 220, since it only needs to provide lighting function, it can use materials with lower cost such as ABS, PS, PMMA, and PC.

[0028] The light-absorbing layer 140 is mainly used to absorb light. Specifically, the light-absorbing layer 140 is black velvet. Black itself has good absorption of visible light, and the surface of the velvet itself is rough and porous. This structure can increase the multiple reflections of light on the surface of the fabric. Each time the light is reflected inside the fabric, a certain proportion of the light is absorbed. After multiple reflections, the light is almost completely absorbed, which greatly improves the light absorption effect of the light-absorbing layer 140 and further improves the image clarity when the whole is used as a mirror.

[0029] Furthermore, the diffusion layer 210 is an annular plate, the semi-transparent and semi-reflective layer 110 is located within the diffusion layer 210, the second light guide layer 220 extends around the diffusion layer 210, and the second lamp body 230 is located at the end of the second light guide layer 220. When the whole unit is used as a mirror, the annular diffusion layer 210 is arranged outside the beauty module used as a mirror, the second lamp body 230 emits light into the second light guide layer 220, the second light guide layer 220 guides the light, and then the light is emitted after the diffusion layer 210 uniformly diffuses the light, thus forming uniform light around the outside of the mirror, improving the user experience.

[0030] There can be only one second lamp body 230. In this case, the light may be weak at the position where the second light guide layer 220 is far from the second lamp body 230. Therefore, in this embodiment, the second lamp body 230 is provided at both ends of the second light guide layer 220. When the lighting module is working, the two second lamp bodies 230 provide light from both ends of the second light guide layer 220, thereby guiding the light from both ends of the second light guide layer 220 to the middle of the second light guide layer, improving the brightness and thus improving the lighting function when used as a mirror.

[0031] In some embodiments, the second light guide layer 220 is located behind the first lamp body 150, and the inner annular portion of the diffusion layer 210 abuts against the rear side of the semi-transparent and semi-reflective layer 110. The lighting module and the phototherapy module are arranged in a front-to-back direction, and the inner annular portion of the diffusion layer 210 abuts against the rear side of the semi-transparent and semi-reflective layer 110, making the overall connection structure more compact.

[0032] In some embodiments, the outer annular portion of the diffusion layer 210 extends backward at an angle. The angled arrangement of the diffusion layer 210 can enclose a region that gradually expands backward, facilitating connection with external structures such as lamp housings, improving the overall appearance. Furthermore, an area for mounting the second light guide layer 220 can be formed in front of the diffusion layer 210, resulting in a tighter overall connection.

[0033] Furthermore, an air gap 300 is formed between the annular inner portion of the diffusion layer 210 and the semi-transparent and semi-reflective layer 110. The air gap 300 formed between the two can accommodate the installation of external structural components, such as control keys. In use, the function can be switched through the control keys within the air gap 300.

[0034] The ratio of reflectivity to transmittance of the semi-transparent and semi-reflective layer 110 can be between 0.8 and 1.2. In this embodiment, the ratio of reflectivity to transmittance of the semi-transparent and semi-reflective layer 110 is 1. When the system is switched to the phototherapy beauty function, light passing through the first light guide layer 120 can be transmitted outward through the semi-transparent and semi-reflective layer 110. At this time, the transmittance of the semi-transparent and semi-reflective layer 110 is mainly reflected. When the system is switched to the mirror function, external light is reflected outward through the semi-transparent and semi-reflective layer 110. At this time, the reflectivity of the semi-transparent and semi-reflective layer 110 is mainly reflected. Within this ratio range, the light transmission and light reflection functions of the semi-transparent and semi-reflective layer 110 can be balanced.

[0035] To further enrich the overall functionality, in this embodiment, both the first lamp body 150 and the second lamp body 230 are adjustable spectrum lamps. Adjustable spectrum lamps can simulate and adjust light of different wavelengths to meet people's functional needs for phototherapy and lighting, thus improving the flexibility of use.

[0036] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
