[0002] This utility model relates to the field of light-emitting modules, specifically to a light-emitting module, a beauty mirror, a sun visor, a light-emitting device, and a vehicle. Background Technology

[0003] The increasingly fast pace of modern life, especially with the advancement of urbanization, means that people spend most of their time working, studying, and living indoors. With prolonged indoor activities, people have less and less exposure to sunlight, which not only affects their physical health but may also lead to various health problems. The red light component of sunlight is widely recognized for its significant positive effects on promoting blood circulation, improving skin condition, and enhancing immunity. Red light can penetrate deep into the skin, promoting cell metabolism and accelerating metabolism, thus having beautifying, anti-aging effects on the skin.

[0004] However, natural light contains not only beneficial red light but also harmful ultraviolet (UV) light. Long-term exposure to UV rays can lead to health problems such as skin aging, sunburn, and even skin cancer. Therefore, modern people want to enjoy the health benefits of sunlight while effectively avoiding the harmful effects of UV rays. Especially in daily life, they tend to utilize only the beneficial effects of red light and avoid UV exposure. Thus, how to effectively obtain the beneficial effects of red light while avoiding the harmful effects of UV rays in environments where direct sunlight is not possible has become a pressing technical problem to be solved.

[0076] It should be noted that the embodiments of the present application and the features in different embodiments can be combined with each other without conflict.

[0077] The present application provides a solution to the problems existing in the prior art. The present application provides a light-emitting module, a beauty mirror, a sun visor, a light-emitting device, and a vehicle, wherein the light-emitting module has a light-emitting area and a non-light-emitting area, and comprises: a protective layer; a reflective electrode layer located on one side of the protective layer and at least partially in the light-emitting area, the reflective electrode layer being made of a light-reflecting material; a light-emitting unit layer located on the side of the reflective electrode layer away from the protective layer and in the light-emitting area, the light-emitting unit layer comprising a plurality of light-emitting elements, at least some of which emit red light when energized; a light-transmitting electrode layer located on the side of the light-emitting unit layer away from the reflective electrode layer and at least partially in the light-emitting area; and a substrate located on the side of the light-transmitting electrode layer away from the light-emitting unit layer; wherein the light-emitting module comprises a light-emitting state and a mirror state. The light-emitting module, beauty mirror, sun visor, light-emitting device, and vehicle of the present application can effectively simulate the red light component in sunlight in the light-emitting state, allowing users to safely and conveniently enjoy the benefits of red light on the skin and health while avoiding the potential harm of ultraviolet light, and can be used as a clear imaging mirror in the mirror state.

[0078] The above is the core idea of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application. The technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application.

[0079] As shown in Figure 1 The embodiment of the present application provides a light-emitting module 10, which comprises, in sequence: a protective layer 11, a reflective electrode layer 12, a light-emitting unit layer 13, a light-transmitting electrode layer 14, and a substrate 15.

[0080] Specifically, the reflective electrode layer 12 is at least partially located in the light emitting region, and serves as a cathode of the light emitting unit layer 13. The reflective electrode layer 12 includes a plurality of cathodes, each of which is electrically connected to one light emitting element of the light emitting unit layer 13 and supplies power to the light emitting element. In addition, the reflective electrode layer 12 is made of a light-reflecting material, and is used to reflect ambient light entering the reflective electrode layer 12 from the substrate 15, so that the light emitting module 10 presents a mirror state when not powered on, and is used to reflect light emitted from the light emitting unit layer 13 and directed to the reflective electrode layer 12 when the light emitting module 10 is powered on and emits light, so that the light is emitted from the light emitting direction of the light emitting module 10, thereby improving the light emitting efficiency of the light emitting module 10.

[0081] Specifically, the light emitting unit layer 13 is located in the light emitting region and emits light in a powered-on state. The light emitting unit layer 13 includes a plurality of light emitting elements, at least some of which emit red light when powered on, so that the light emitting module 10 can effectively simulate the red light component in sunlight, allowing users to safely and conveniently enjoy the benefits of red light on the skin and health. Red light is widely recognized as having important positive effects on promoting blood circulation, improving skin condition, and enhancing immunity, etc. Red light can penetrate deep into the skin, promote cell metabolism, and accelerate metabolism, thereby having the effects of beautifying and rejuvenating the skin and delaying aging.

[0082] Specifically, the light-transmitting electrode layer 14 is at least partially located in the light emitting region, and serves as an anode of the light emitting unit layer 13. The light-transmitting electrode layer 14 includes a plurality of anodes, each of which is electrically connected to one light emitting element of the light emitting unit layer 13 and supplies power to the light emitting element. In addition, the light-transmitting electrode layer 14 is made of a transparent material, and is used to allow ambient light entering the light-transmitting electrode layer 14 from the substrate 15 to pass through the light-transmitting electrode layer 14, or to allow light emitted from the light emitting unit layer 13 to pass through the light-transmitting electrode layer 14, so that the light emitting module 10 presents a light emitting state when powered on and a mirror state when not powered on.

[0083] Further, the light emitting module 10 has a light emitting state when the light emitting unit layer 13 emits light and a mirror state when the light emitting unit layer 13 does not emit light. When the light emitting module 10 is in the light emitting state, it can provide red light to users, allowing them to safely and conveniently enjoy the benefits of red light on the skin and health. When the light emitting module 10 is in the mirror state, it can be used as a clear mirror, improving the multiplicity of the light emitting module 10.

[0084] In some embodiments, all the light emitting elements of the light emitting unit layer 13 emit red light when powered, so that the light emitting module 10 emits infrared light when powered, without including other colors of light. In turn, the light emitting module 10 can effectively simulate the red light component in sunlight, so that the user can safely and conveniently enjoy the benefits of red light on the skin and health while avoiding harmful ultraviolet light. That is, the light emitting module 10 of the present application can retain beneficial red light compared to sunlight, and avoid harmful ultraviolet light.

[0085] In some embodiments, the light emitting elements include one or a combination of organic light emitting diodes or active matrix organic light emitting diodes. Since organic light emitting diodes (OLED) or active matrix organic light emitting diodes (AMOLED) use different light emitting materials, these light emitting materials emit three colors of light, i.e. red, green and blue light, when powered. Therefore, the present application can select organic light emitting diodes or active matrix organic light emitting diodes, and make the light emitting materials in the organic light emitting diodes or active matrix organic light emitting diodes be red light emitting materials, so that all the light emitting elements of the light emitting unit layer 13 emit red light when powered. In turn, the light emitting module 10 can retain beneficial red light compared to sunlight, and avoid harmful ultraviolet light. Further, the red light emitting materials can be selected from one or a combination of phosphor-based materials, thermally activated delayed fluorescence (TADF) materials, organic small molecule materials, organic polymer materials, iridium-based complexes, or rare earth metal complexes.

[0086] In some embodiments, when the light emitting module 10 is in a light emitting state, the light emitting module 10 is powered, and the light emitting unit layer 13 of the light emitting area emits red light. That is, the light emitting module 10 at this time is in a red light emitting working state, which can provide red light for the user. Further, the wavelength range of the red light emitted by the light emitting module 10 is 600nm-800nm. When the wavelength range of the red light is in the above range, the effect on promoting blood circulation, improving skin condition and enhancing immunity is most significant. Specifically, the wavelength of the red light emitted by the light emitting module 10 can be any one of 600nm, 650nm, 700nm, 750nm or 800nm, which is not limited by the present application.

[0087] As Figure 2As shown, in related technologies, the semi-transparent mirror 50 includes a reflective layer 51 and a protective layer 52. The semi-transparent mirror 50 is typically used in applications that allow some light to pass through, possessing a certain degree of light transmittance and reflectivity. However, its high transmittance and low reflectivity often make it unsuitable as a mirror. While allowing some light to pass through is advantageous in some applications, when used for a mirror effect, the semi-transparent mirror 50 cannot effectively reflect enough light to form a clear image. Due to the low reflectivity of the semi-transparent mirror 50, the amount of light reflected by the mirror is limited, insufficient to produce a clear and distinct image. This results in a blurred mirror effect, failing to achieve the clear image quality of traditional mirrors with high reflectivity. Specifically, the cause of this problem is the low thickness of the semi-transparent layer material used in the semi-transparent mirror 50, which allows for a certain degree of light transmittance and reflectivity. Furthermore, in related technologies, the low thickness of the reflective layer 51 used in light-emitting devices with both light-emitting and specular reflection functions also leads to a blurred mirror effect, failing to achieve the clear image quality of traditional mirrors with high reflectivity.

[0088] like Figure 3 As shown, to address the aforementioned issues, in some embodiments, when the light-emitting module 10 is in a mirror state, the light-emitting module 10 is not powered on, and the reflective electrode layer 12 of the light-emitting area reflects ambient light incident from the substrate 15 to make the light-emitting area appear mirror-like. The reflective material of the reflective electrode layer 12 is an opaque, highly reflective metallic material, specifically including silver or aluminum, or a combination of both. The thickness of the reflective electrode layer 12 is 100nm to 300nm, and the reflectivity of the light-emitting area is 50% to 99%. By using silver or aluminum as the reflective material of the reflective electrode layer 12 and setting the aforementioned thickness, the light-emitting area of ​​the light-emitting module 10 can achieve the aforementioned reflectivity, thereby enabling the light-emitting module 10 to reflect most of the ambient light when not powered on, forming a clear image quality, thus making the light-emitting module 10 appear mirror-like.

[0089] Specifically, the thickness of the reflective electrode layer 12 can be any one of 100nm, 120nm, 150nm, 180nm, 200nm, 220nm, 250nm, 280nm, or 300nm, and this invention does not limit this. The reflectivity of the light-emitting area can be any one of 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, or 99%, and this invention does not limit this.

[0090] like Figure 4As shown, in some embodiments, the light emitting unit layer 13 comprises, in sequence from the reflective electrode layer 12 to the light-transmitting electrode layer 14, an electron injection layer 131, a first electron transport layer 132, a first red light emitting material layer 133, a first hole transport layer 134, a charge generation layer 135, a second electron transport layer 136, a second red light emitting material layer 137, a second hole transport layer 138, and a hole injection layer 139. The light emitting module 10 only uses red light emitting material layers, which can retain beneficial red light and avoid harmful ultraviolet light compared to sunlight. In addition, the light emitting module 10 uses the first red light emitting material layer 133 and the second red light emitting material layer 137, which can effectively increase the amount of red light emitted by the light emitting module 10, further improving the beneficial effects on the human body.

[0091] Further, the thickness of the first red light emitting material layer 133 and / or the second red light emitting material layer 137 is 5nm-50nm, which can make the wavelength range of the red light emitted by the red light emitting material when powered meet 600nm-800nm. Specifically, the thickness of the first red light emitting material layer 133 and / or the second red light emitting material layer 137 can be any one of 5nm, 10nm, 15nm, 20nm, 25nm, 30nm, 35nm, 40nm, 45nm or 50nm, and the utility model does not limit this.

[0092] With reference to Figure 4 , the reflective electrode layer 12, the light emitting unit layer 13, the light-transmitting electrode layer 14 and the power IC (power chip) are electrically connected, thereby forming a communication loop, so that the red light emitting material of the light emitting unit layer 13 can emit red light when powered.

[0093] As shown in Figure 5 , in some embodiments, part of the reflective electrode layer 12 forms a cathode interface 16 in the non-light emitting area, and part of the light-transmitting electrode layer 14 forms an anode interface 17 in the non-light emitting area, the cathode interface 16 and the anode interface 17 are used to be electrically connected with the power supply voltage to make the light emitting module 10 emit light. The cathode interface 16 and the anode interface 17 are arranged in the non-light emitting area, which is convenient for electrical connection with the power IC.

[0094] Specifically, the power voltage of the light emitting module 10 is less than or equal to 12V. Since the light emitting module 10 can be built-in power supply or use external power supply, the power voltage of the light emitting module 10 is set to be less than or equal to 12V, which can improve the versatility of the light emitting module 10, and be compatible with the 12V voltage commonly used in automobiles, thereby making the light emitting module 10 can be used in environments such as automobiles.

[0095] With reference to Figure 1In some embodiments, the light emitting module 10 further comprises an encapsulation structure 18. The encapsulation structure 18 is located in the non-light emitting area, and surrounds the light emitting unit layer 13. The encapsulation structure 18 is located between the protective layer 11 and the substrate 15 and bonds the protective layer 11 and the substrate 15 to form a sealed space, and the light emitting unit layer 13 is located in the sealed space. The encapsulation structure 18 is used to encapsulate the light emitting module 10 to avoid water and oxygen in the air from corroding the light emitting unit layer 13.

[0096] Specifically, the material of the encapsulation structure 18 comprises one or a combination of ultraviolet curing glue (UV glue) or glass glue to improve the encapsulation strength of the light emitting module 10.

[0097] With reference back to Figure 1 In some embodiments, the protective layer 11 covers the light emitting area, and the material of the protective layer 11 comprises one or a combination of glass, acrylic, aluminum or copper. That is, the protective layer 11 can be made of the same transparent material as the substrate 15 to save cost, or can be made of opaque materials such as aluminum or copper to improve the strength of the light emitting module 10.

[0098] With reference back to Figure 1 In some embodiments, the substrate 15 covers the light emitting area and the non-light emitting area, and the material of the substrate 15 comprises one or a combination of glass, acrylic, polyimide, polyethylene terephthalate or polyethylene naphthalate. That is, the substrate 15 must be made of a transparent material to improve the front transmittance of the light emitting module 10 to form a good mirror effect when the light emitting module 10 is not powered.

[0099] With reference back to Figure 1 In some embodiments, the area of the substrate 15 is larger than the area of the protective layer 11. Based on the above arrangement, a lead interface or a flexible printed circuit board (FPC) can be formed on the substrate 15 for circuit connection of the light emitting module 10.

[0100] The light emitting module 10 of the utility model can emit red light, effectively simulate the red light component in sunlight in a light emitting state, enable users to safely and conveniently enjoy the benefits of red light on the skin and health, and avoid potential hazards of ultraviolet light, and be used as a clear mirror in a mirror state.

[0101] As Figure 6 shown, on the other hand, the embodiment of the utility model further provides a cosmetic mirror 20, which comprises a first shell 21 and the above-mentioned light emitting module 10.

[0102] Specifically, the light-emitting module 10 is connected with the first shell 21, and at least a light-emitting area of the light-emitting module 10 is exposed, so that the light-emitting module 10 can emit red light to irradiate a user when powered on. The specific implementation of the light-emitting module 10 can refer to the foregoing embodiments, and the repeated parts will not be described herein.

[0103] The cosmetic mirror 20 of the utility model, through propose a kind of containing the cosmetic mirror 20 of the light-emitting module 10 that can emit red light, can effectively simulate the red light component in sunlight under the light-emitting state of light-emitting module 10, so that user can safely, conveniently enjoy the benefit of red light to skin and health, while avoiding the potential harm of ultraviolet rays;Meanwhile, the cosmetic mirror 20 can also be set indoors, increase the time of irradiating red light when user cannot sunbathe indoors.In addition, under the mirror surface state of light-emitting module 10, the cosmetic mirror 20 can also be used as a clear imaging mirror.

[0104] In many daily scenes, especially during driving, people have little opportunity to expose to sunlight for a long time, especially in the case where ultraviolet rays cannot be avoided. Due to the busy work and life, drivers often cannot effectively utilize the red light component of sunlight to improve skin health and beauty, especially in the case of long driving or heavy traffic, sunbathing becomes a luxury and difficult to achieve behavior. Therefore, how to effectively obtain the beneficial effect of red light in the environment where direct sunbathing is not possible, while avoiding the damage of ultraviolet rays, becomes a technical problem to be solved.

[0105] For the above problems, as shown in Figure 7 Another aspect, the utility model discloses a sun visor 30, comprising: second shell 31 and the light-emitting module 10 described above.

[0106] Specifically, the light-emitting module 10 is connected with the second shell 31, and at least a light-emitting area of the light-emitting module 10 is exposed, so that the light-emitting module 10 can emit red light to irradiate a user when powered on. The specific implementation of the light-emitting module 10 can refer to the foregoing embodiments, and the repeated parts will not be described herein.

[0107] The sun visor 30 of the utility model, through propose a kind of containing the sun visor 30 of the light-emitting module 10 that can emit red light, can effectively simulate the red light component in sunlight under the light-emitting state of light-emitting module 10, so that user can safely, conveniently enjoy the benefit of red light to skin and health, while avoiding the potential harm of ultraviolet rays;Meanwhile, the sun visor 30 can also be set in the car interior, increase the time of irradiating red light when user cannot sunbathe during driving.In addition, under the mirror surface state of light-emitting module 10, the sun visor 30 can also be used as a clear imaging mirror.

[0108] As shown in Figure 8As shown, in another aspect, embodiments of the present invention also provide a light-emitting device 60, including the aforementioned light-emitting module 10. The light-emitting device 60 can be: a beauty mirror 20, a desktop makeup mirror, a handheld makeup mirror, a powder compact, a bathroom mirror, or a dressing mirror, or any other mirror including the aforementioned light-emitting module 10; or a sun visor 30 or an earphone case, or any other device including the aforementioned light-emitting module 10.

[0109] The light-emitting device 60 of this invention proposes a light-emitting module 10 that can emit red light, which can effectively simulate the red light component in sunlight in the light-emitting state, so that users can safely and conveniently enjoy the benefits of red light to the skin and health, while avoiding the potential harm of ultraviolet rays, and can be used as a clear mirror in the mirror state.
