In some embodiments, the light-transmitting portion and the light-blocking portion are integrally formed through dual-color injection molding.

In some embodiments, a light transmission rate of the light guide element is 40% to 60%, and a thickness of the light guide element is 0.65 mm to 0.75 mm.


In some embodiments, a reflectance of the first reflective film and a reflectance of the second reflective film are both greater than or equal to 80%, a light transmission rate of the first reflective film is 0.3% to 0.5%, and a light transmission rate of the second reflective film is 0.2% to 0.4%.


In some embodiments, a material of the first reflective film and the second reflective film is white Polyethylene Terephthalate (PET).

In some embodiments, the breathing light module further includes a first adhesive layer and a second adhesive layer, the first decorative ring is connected to the lightshade via the first adhesive layer, and the second decorative ring is connected to the lightshade via the second adhesive layer.


In some embodiments, the present disclosure further provides an electronic device, including a camera module and the above-mentioned breathing light module. The camera module faces the light guide element, and the light guide element is arranged to surround an optical axis of the camera module.


As shown in FIG. 1, in some embodiments of the present disclosure, a breathing light module 10 may be applied to an electronic device such as a mobile phone, a tablet computer, a smartwatch, etc. The breathing light module 10 may be configured to indicate information. For example, in scenarios such as incoming call display, text message notifications, and charging indicators during the use of the electronic device, the breathing light module 10 may flash to provide a reminder effect.


As shown in FIGS. 1 and 2, the breathing light module 10 includes a light guide element 11, a light source assembly 12, a first reflective film 13, and a second reflective film 14. The light guide element 11 has a first annular surface 11a and a second annular surface 11b arranged on two opposite sides. A groove 11c is defined on a side of the light guide element 11 where the first annular surface 11a is located. The light emitting portion 12a of the light source assembly 12 is at least partially arranged within the groove 11c, so that a light emitted from the light emitting portion 12a may enter the light guide element 11. The first reflective film 13 is arranged on the first annular surface 11a, and the second reflective film 14 is arranged on the second annular surface 11b. By using the first reflective film 13 and the second reflective film 14 to reflect the light and prevent the light from emitting from the first annular surface 11a and the second annular surface 11b may ensure that the light entering the light guide element 11 is emitted from a periphery of the light guide element 11. Thus, when a camera module 20 of the electronic device is arranged opposite the light guide element 11, the light emitted from the light guide element 11 is directed away from an optical axis of the camera module 20, which effectively reduces the likelihood of light crosstalk. Moreover, this structural setting may maintain the overall aesthetic appearance of the breathing light module 10.


It should be noted that a coverage area is formed by the second reflective film 14 covering on the second annular surface 11b, and an orthogonal projection of the light emitting portion 12a on the second annular surface 11b falls within the coverage area. As a result, when the light source assembly 12 emits light, the second reflective film 14 may provide a good reflective effect, preventing the light guide element 11 from being brighter at a position directly opposite to the light source assembly 12 than the light guide element 11 being at other positions, thus avoiding the phenomenon of a bright spot.


Furthermore, the periphery of the light guide element 11 is arranged with a light concentrating portion 11d. The light concentrating portion 11d is configured to converge the light incident on the light concentrating portion 11d and emit the light from the periphery of the light guide element 11. In this way, although the light from the light source assembly 12 may weaken as it propagates to the light concentrating portion 11d, the light concentrating portion 11d has a focusing effect on the light, thus preventing the occurrence of a dark spot and effectively improving the uniformity of light emission from various positions along the periphery of the light guide element 11.


The light concentrating portion 11d includes multiple sawteeth. The multiple sawteeth are arranged sequentially along the periphery of the light guide element 11. When the light propagating through the light guide element 11 exits from the light concentrating portion 11d, the multiple sawteeth may converge the light, enabling the light emitted from a position corresponding to the light concentrating portion 11d to be bright. This solves the problem of decreased light flux resulting in dimness, which occurs due to light loss during a propagation of the light emitted from the light source assembly 12 along the light guide element 11.


In some embodiments, the light guide element 11 has at least two grooves 11c defined thereon. The periphery of the light guide element 11 is arranged with at least two light concentrating portions 11d. The grooves 11c and the light concentrating portions are alternatively arranged along a circumferential direction of the light guide element 11. When the light emitted from the light emitting portion 12a at the groove 11c propagates through the light guide element 11 to the corresponding light concentrating portion 11d, the light concentrating portion 11d may have a focusing effect on the light, thereby preventing the occurrence of shadows and dark spots at a position corresponding to the light concentrating portion 11d.


Furthermore, any interval between any one of the at least two grooves 11c and an adjacent one of the at least two light concentrating portions 11d is equal, so as to improve the uniformity of the light emitted from the light guide element 11, enabling an annular light effect emitted by the breathing light module 10 to be softer and preventing the occurrence of local bright spots or dark spots.


It should be noted that the light emitted by the light source assembly 12 may be monochromatic light or multi-colored light. In some embodiments, the light source assembly 12 include a LED light. A position of a light emitting surface of the LED light forms the light emitting portion 12a. The LED light include at least one of a red LED light 121, a green LED light 122, and a blue LED light 123. It can be understood that the red LED light 121 is configured to emit red light, the green LED light 122 is configured to emit green light, and the blue LED light 123 is configured to emit blue light. Accordingly, when the red LED light 121 and the green LED light 122 emit light simultaneously, a mixed color light formed by the red light and the green light may be obtained; when the red LED light 121 and the blue LED light 123 emit light simultaneously, a mixed color light formed by the red light and the blue light may be obtained. In this way, the breathing light module 10 may emit mixed color effects, and thus enhancing the expressiveness.


A color mixing principle of two different colored lights will be explained below as shown in FIG. 3.


As shown in FIG. 3, when the angle θ between two light points (i.e., bright spots emitted by two different colored LED lights) and a line of sight of a human eye is sufficiently large, the human eye may distinguish that these are two separate light points. When the angle θ between the two light points and the line of sight of the human eye is sufficiently small, the human eye may perceive them as one single point. This critical angle is called a minimum resolvable angle of the human eye, which is approximately one minute of angle. It can be understood that as 1 degree equals to 60 minutes of angle, the minimum resolvable angle of the human eye is approximately (1/60) degree. When the angle formed by the two light points to the human eye is smaller than the minimum resolvable angle, images will overlap and appear as a single point, and a color of the point is a mixture of the colors of the two light points.


As shown in FIG. 4, the breathing light module 10 further includes a lightshade 15. The lightshade 15 includes a light-transmitting portion 151 and a light-blocking portion 152 connected together. The lightshade 15 covers the second annular surface 11b of the light guide element 11 and the peripheral side surface 11e of the light guide element 11 for enabling at least a part of the light-transmitting portion 151 to face the light guide element 11. It can be understood that the peripheral side surface 11e of the light guide element 11 is a surface located on an outer periphery of the first annular surface 11a and the second annular surface 11b of the light guide element 11. When the light emitting portion 12a emits light, the light guide element 11 directs the light from the periphery to the light-transmitting portion 151, and the light is emitted from the periphery of the light-transmitting portion 151. Since the light emitted from the light guide element 11 is directed from the periphery, and the light-transmitting portion 151 also emits light from a periphery of the light-transmitting portion 151. Thus when the breathing light module 10 emits light, the light emitted by the breathing light module 10 appears to radiate from the periphery of the breathing light module 10 the light emitted by the breathing light module 10 appears to be emitted from the periphery of the breathing light module 10 that is away from a center of the light guide element 11. As a result, the light will not enter the camera module 20 located at the center of the light guide element 11, thereby reducing the likelihood of light crosstalk.


Furthermore, the light-transmitting portion 151 and the light-blocking portion 152 are integrally formed through dual-color injection molding, which may maintain the overall structural strength and facilitate processing. In some embodiments, the light-transmitting portion 151 is made of transparent PC1250Z injected plastic material with 1% of white titanium dioxide and 1% of T150 diffusion powder. The light-blocking portion 152 is made of gray PC1414 injected plastic material with 1% of white titanium dioxide, enabling the light-blocking portion 152 to have low light transmission. Both the light-transmitting portion 151 and the light-blocking portion 152 are made from pelletized materials to ensure consistency of colorants. It should be noted that a light-block effect of the light-blocking portion 132 may be achieved with the aforementioned materials. In some embodiments, the light-blocking effect of the light-blocking portion 152 may also be achieved by attaching a light-blocking film. For example, the lightshade 15 may be made of transparent plastic or transparent glass, with a light-blocking film attached to a position near a lower part of the lightshade 15 and that corresponds to the light emitting portion 12a, so that the position covered by the light-blocking film may not transmit light, or the light flux passing through is negligible, thereby forming the light-blocking portion 152. Alternatively, the light-blocking portion 152 may be formed by spraying ink (such as black ink) onto the lightshade 15. The present disclosure does not limit the method for forming the light-blocking portion 152.


In some embodiments of the present disclosure, taking the example where three different colored LED lights are arranged in the groove 11c, as shown in FIGS. 4 and 5, after passing through the light guide element 11, the light emitted by these LED lights in the groove 11c is converged again to form a luminous area P on the surface of the breathing light module 10 (e.g., an outer surface of the lightshade 15. It can be understood that the further the light source assembly 12 is from the luminous area P, the smaller the angle θ of the mixed colors becomes. Simulation results show that when a distance between the light source assembly 12 and the luminous area P exceeds 5 mm, the human eye may not distinguish original colors of the three different colored LED lights, thereby achieving a good color mixing effect.


In some embodiments, as shown in FIG. 4, the red LED light 121, green LED light 122, and blue LED light 123 are arranged side by side within the groove 11c. The green LED light 122 is arranged on an inner side of the red LED light 121, and the blue LED light 123 is arranged on an outer side of the red LED light 121. The inner side of the red LED light 121 faces the center of the light guide element 11. In some embodiments, the green LED light 122, which has a longer wavelength, is arranged on the inner side, i.e., on a side of the light guide element 11 far from the lightshade 15, thereby avoiding the issue of a greenish tint in the mixed color effect.


In some embodiments, a light transmission rate of the light guide element 11 is 40% to 60%, and the thickness is 0.65 mm to 0.75 mm. It should be noted that in some embodiments, 9% to 11% by weight of diffusion powder is added to the material of the light guide element 11, which increases a refraction path of light within the light guide element 11, thereby further increasing a mixing distance between the light emitted by different colored LED lights, making the color mixing effect more uniform and preventing the issue of localized color deviation. The specific diffusion powder may be Lumiplas LD7750 (LGLD7750), the weight percentage of which in the material of the light guide element 11 may be 9%, 10% or 11%. A main material of the light guide element 11 may be polycarbonate to achieve good light transmission effects. For example, the material of the light guide element 11 may include Teijin PC-L-1225Y, and the weight percentage of Teijin PC-L-1225Y in the material of the light guide element 11 may be 90%. The material of the light guide element 11 will not be repeated here.


In some embodiments, a reflectance of the first reflective film 13 and a reflectance of the second reflective film 14 are both greater than or equal to 80%. A light transmission rate of the first reflective film 13 is 0.3% to 0.5%, and a light transmission rate of the second reflective film 14 is 0.2% to 0.4%. This allows the reflectance and light transmission rate of the first reflective film 13 and the second reflective film 14 to be controlled within suitable ranges, facilitating good reflective effects and ensuring that the light entering the light guide element 11 is emitted from the periphery of the light guide element 11. The materials of the first reflective film 13 and the second reflective film 14 may specifically be white PET. In some embodiments, the first reflective film 13 is double-sided adhesive tape, and the second reflective film 14 is single-sided adhesive tape, which makes it easier to attach the first reflective film 13 to the first annular surface 11a, and attach the second reflective film 14 to the second annular surface 11b.


As shown in FIG. 4, when the first reflective film 13 is double-sided adhesive tape, after the first reflective film 13 is attached to the first annular surface 11a, a circuit board 12b of the light source assembly 12 may be bonded to a side of the first reflective film 13 facing away from the light guide element 11. It can be understood that the LED light of the light source assembly 12 may be arranged on the circuit board by methods such as surface-mounting or adhesive bonding. As the circuit board is adjacent to the light guide element 11, the LED light is arranged in the groove 11c.


As shown in FIGS. 4 and 5, a first stepped groove 15a and a second stepped groove 15b are defined on the light-transmitting portion 151. The first stepped groove 15a is configured to arrange a first decorative ring 16 therein, and the second stepped groove 15b is configured to arrange a second decorative ring 17 therein. The first decorative ring 16 is sealingly connected to a top surface of the light-transmitting portion 151, and the second decorative ring 17 is sealingly connected to a step surface of the second stepped groove 15b, thus effectively ensuring an internal sealing of the breathing light module 10, facilitating waterproof and dustproof protection for the light source assembly 12 and the camera module 20 arranged inside. It should be noted that the light guide element 11 is arranged on a side of the light-transmitting portion 151 opposite to the second stepped groove 15b, and the inner circle of the light guide element 11 corresponds to the inner circle of the second decorative ring 17, enabling external light to pass through the second decorative ring 17 and the light guide element 11, eventually entering the camera module 20. It should be noted that in the present disclosure, the “inner circle” refers to a ring formed by an inner side wall of an annular structural member, and the “outer circle” refers to a ring formed by an outer side wall of an annular structural member. Taking the light guide element 11 as an example, the inner circle of the light guide element 11 is a ring formed by a sidewall of a central hole of the light guide element 11, and correspondingly, the outer circle of the light guide element 11 is a ring formed by a peripheral side surface 11e of the light guide element 11.


An installation groove 17c is defined on the second decorative ring 17. The installation groove 17c is configured to install a camera lens 20a. The camera lens 20a faces the camera module 20, and the camera lens 20a serves the purposes of beautification, decoration, and protection. It should be noted that the camera lens 20a may be connected to the second decorative ring 17 by optical adhesive or it may be snap-fitted within the installation groove 17c. The present disclosure does not limit this.


In some embodiments, the second decorative ring 17 includes a first stop wall 17a and a second stop wall 17b. The first stop wall 17a is arranged on the inner circle of the second decorative ring 17, and the second stop wall 17b is arranged on the outer circle of the second decorative ring 17. The first stop wall 17a abuts the inner circle of the light-transmitting portion 151, and the second stop wall 17b abuts the inner circle of the first decorative ring 16. This structural arrangement is compact, and the second decorative ring 17 is less likely to become loose from the first decorative ring 16, resulting in a robust overall structure for the breathing light module 10 with high impact resistance.


As shown in FIGS. 6 and 7, in some embodiments, the present disclosure provides an electronic device 100 that includes the above-described breathing light module 10. The electronic device 100 further includes the camera module 20, with the camera module 20 arranged facing the light guide element 11, and the light guide element 11 arranged to surround the optical axis of the camera module 20. When the breathing light module 10 operates, the light is emitted from the periphery of the light guide element 11, which does not enter the camera module 20, and thus effectively reducing the likelihood of light leakage during operation. At the same time, when the breathing light module 10 works, it may form an annular light effect around the camera module 20, enhancing the overall aesthetic appearance and improving the user experience.


As shown in FIGS. 7 and 8, in some embodiments where the breathing light module 10 includes the lightshade 15, the first decorative ring 16, and the second decorative ring 17, the first decorative ring 16 is connected to the lightshade 15 via a first adhesive layer and the second decorative ring is connected to the lightshade 15 via a second adhesive layer 19. The first adhesive layer 18 and the second adhesive layer 19 may be formed by curing adhesive or may be double-sided adhesive tape. The present disclosure does not limit this.


An outer side of the lightshade 15 may be connected to a casing of the electronic device 100 (e.g., a rear cover 101) via adhesive or double-sided tape, thereby installing the entire breathing light module 10 onto the electronic device 100. It can be understood that a region of the light-transmitting portion 151 from which the light emitted (i.e., the luminous area P) is exposed between the rear cover 101 and the first decorative ring 16, so that when the breathing light module 10 operates to emit light, an annular light effect is formed around the periphery of the light-transmitting portion 151.


In some embodiments, the lightshade 15 may also be connected to a front cover of the electronic device 100. The light guide element 11 is arranged to correspond to a front-facing camera. In this case, the breathing light module 10 may form an annular light effect around the front-facing camera.


As shown in FIG. 9, FIG. 9 is a schematic structural view of the electronic device 100 in some embodiments of the present disclosure. The electronic device 100 may include a radio frequency (RF) circuit 501, a memory 502 with one or more computer-readable storage media, an input unit 503, a display unit 504, a sensor 505, an audio circuit 506, a wireless fidelity (Wi-Fi) module 507, a processor 508 with one or more processing cores, a power supply 509, etc. Those skilled in the art should understand that the structure of the electronic device 100 shown in FIG. 9 does not limit the structure of the electronic device 100; it may include more or fewer components than those shown, or some components may be combined, or different component arrangements may be used.


The radio frequency (RF) circuit 501 is configured to receive and transmit information or a signal during a call.
