Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a light-emitting device and an atomizer. Background Technology

[0002] In modern consumer electronics and various embedded indicator lights, the pursuit of ultra-thin, narrow-bezel, and even irregularly shaped displays has compressed the internal optical structure space. Due to thickness or layout limitations, the light-emitting units (LED beads) cannot face the same direction as the final display area (i.e., direct-lit backlighting is not possible), and must instead be positioned on the side for light emission. Furthermore, the light must ultimately be emitted uniformly from the top surface of the product, which presents a fundamental challenge to traditional light guide technology. The point light source characteristic of LED beads is amplified; the light emitted, after coupling into the light guide plate from the side, is highly susceptible to influence from the side structure of the light guide plate during its guidance to the top, resulting in uneven brightness in the top display area and compromising overall integrity and uniformity.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] See Figure 1 , Figure 2 and Figure 3 This utility model provides a light-emitting device, such as a light-emitting device for aromatherapy, an indicator light, or a light-emitting device on an electronic product. The light-emitting device includes a light-emitting element 1 and a light-guiding assembly 2. The light-emitting element 1 is, for example, an LED bead. The light-guiding assembly 2 includes a light-guiding element 20, a diffuser 30, a first light-leakage prevention element 410, and a second light-leakage prevention element 420. The light-emitting element 1 and the second light-leakage prevention element 420 are respectively disposed on opposite sides of the light-guiding element 20 along a first direction, and the diffuser 30 and the second light-leakage prevention element 420 are respectively disposed on opposite sides of the light-guiding element 20 along a second direction, with the first and second directions perpendicular to each other. A light-emitting surface 10 is provided on the side of the light-emitting element 1 closest to the light-guiding element 20, a light-incident surface 210 is provided on the side of the light-guiding element 20 closest to the light-emitting element 1, and a light-emitting surface 220 is provided on the side of the light-guiding element 20 closest to the diffuser 30. The light-emitting surface 10 is directly opposite the light-incident surface 210. A first light-diffusing portion 230 is formed on the surface of the light-incident surface 210 convex to the light-emitting surface 10. The first direction is, for example, the vertical direction.

[0032] When the light-emitting element 1 operates, it emits light onto the light-incident surface 210 of the light guide 20. The light is refracted into the interior of the light guide 20 by the first light-diffusing part 230 on the light-incident surface 210. The first light-diffusing part 230 can diffuse the light more evenly into the light guide 20. Then, through total internal reflection, the light is irradiated onto the first light-leakage-proof part 410 located at the bottom of the light guide 20. The first light-leakage-proof part 410 then reflects the light back into the light guide 20 and finally passes out of the light guide 20, refracting onto the diffuser 30. The diffuser 30 then illuminates the entire diffuser 30 through reflection, achieving uniform light emission and uniform brightness of the surface of the diffuser 30.

[0033] The first light-diffusing section 230 can change the angle of light entering the light guide 20 and change the propagation angle of the light inside the light guide 20, so that the light energy inside the light guide 20 is mixed more evenly, further ensuring that the light can be emitted evenly. The first light-diffusing section 230 can be a triangular protrusion, a trapezoidal protrusion, a wavy protrusion, etc. The first light-diffusing section 230 can be, for example, a structure of the light guide 20; or it can be, for example, a separate structure that can be installed on the light-incident surface 210 of the light guide 20.

[0034] Among them, the light guide 20 is made of high-transparency optical plastics such as acrylic or PC (polycarbonate) to ensure that light can pass through smoothly.

[0035] Since light enters the light guide 20 from the second direction through the light-inlet surface 210, some light will be emitted from the side of the light guide 20 away from the light-emitting element 1. The second light-leakage prevention element 420 can block or reflect this part of the light, focusing the light that overflows from the side of the light guide 20 into the light guide 20, so that this part of the light can be reflected out of the light guide 20 through the first light-leakage prevention element 410, thereby improving the light output efficiency and increasing the final light output brightness.

[0036] Among them, the first light leakage prevention component 410 and the second light leakage prevention component 420 can reflect the light that leaks out from the bottom and side of the light guide component 20 back into the light guide component 20 for reuse, further making the light on the light guide component 20 more uniform and bright, and improving the overall brightness.

[0037] The diffuser 30 is, for example, a transparent plate (such as PS (polystyrene), PMMA (acrylic) or PC (polycarbonate), which contains diffuse particles) to re-uniform the light emitted from the light guide 20, so that the light can be emitted more evenly.

[0038] See Figure 2 , Figure 4 , Figure 5 and Figure 6In some embodiments, the first light-diffusing section 230 is a triangular strip structure extending along a second direction. The first light-diffusing section 230 includes a first side surface 231 and a second side surface 232, forming a first included angle C between the first side surface 231 and the second side surface 232. The first included angle C convexes towards the light-emitting surface 10, and the angle of the first included angle C is greater than or equal to 90°. The triangular strip structure provides a clear direction for light refraction, allowing light to be refracted more smoothly into the light guide 20 through the first side surface 231 and the second side surface 232, reducing light reflection, improving incident efficiency, and enhancing the final brightness effect. The angle of the first included angle C between the first side surface 231 and the second side surface 232 is greater than or equal to 90°, causing light to be refracted more smoothly out of the surface of the light guide 20 in a direction closer to the normal, effectively avoiding the formation of local bright spots and further ensuring uniform light emission.

[0039] See Figure 5 and Figure 6 In some embodiments, multiple first light-diffusing sections 230 are provided, and the second included angle D formed between two adjacent first light-diffusing sections 230 is 120°. Since the optimal emission angle of the light-emitting element 1 in the prior art is 120°, areas with angles greater than 120° also emit light, but the emission intensity is low and cannot illuminate the object. Setting the second included angle D between two adjacent first light-diffusing sections 230 to 120° provides better diffusion of light entering the light guide 20, better diffusing the effective light from the side into the light guide 20, further ensuring uniform light output and brightness. The angle of the second included angle D is equal to the angle of the first included angle C, that is, the angle of the first included angle C is 120°.

[0040] See Figure 3 , Figure 4 and Figure 5 In some embodiments, a second light-diffusing portion 240 protrudes from the side of the light-emitting surface 220 facing the diffuser 30. The second light-diffusing portion 240 is a triangular strip-shaped structure extending along the first direction. The second light-diffusing portion 240 can change the direction of the light rays that are ultimately refracted out of the light guide 20, improve the light-diffusing capability of the light guide 20, make the light illuminating the diffuser 30 more uniform, and ultimately make the light reflected out of the diffuser 30 more uniform. The second light-diffusing portion 240 can be, for example, a structure of the light guide 20; or it can be, for example, a separate structure that can be installed on the light-emitting surface 220 of the light guide 20.

[0041] In some embodiments, the first light-diffusing section 230 is a triangular strip structure extending along the second direction, and the second light-diffusing section 240 is a triangular strip structure extending along the first direction. The end of the first light-diffusing section 230 near the diffuser 30 is connected to the end of the second light-diffusing section 240 near the light-emitting element, so that the first light-diffusing section 230 and the second light-diffusing section 240 are connected end to end, maintaining structural uniformity and facilitating production and processing; and when the light emitted by the light-emitting element 1 enters the light guide 20 from the light incident surface 210, it will undergo initial diffusion in the first light-diffusing section 230. During the transmission process, some of the light will make the reflection trend between the first light-diffusing section 230 and the second light-diffusing section 240 consistent, ensuring the uniform light effect of the light guide 20.

[0042] See Figure 5 In some embodiments, multiple first light-diffusing sections 230 and multiple second light-diffusing sections 240 are provided, with each of the multiple first light-diffusing sections 230 and multiple second light-diffusing sections 240 corresponding one-to-one. This ensures that the light entering the reflected light area of ​​the light guide 20 from the light-incident surface 210 is consistent with the reflection trend of the light exiting the light guide 20 from the light-outceasing surface 220, further improving the light-diffusing effect of the light guide 20, thereby ensuring that the light finally emitted from the light guide 20 to the diffuser 30 is more uniform.

[0043] See Figure 3 and Figure 7 In some embodiments, the first distance between the light-incident surface 210 and the light-emitting surface 10 in the first direction is 0.5mm-2mm, so that the light emitted by the light-emitting element 1 can enter the light guide 20 efficiently and uniformly. Since the light from the light-emitting element 1 is divergent, if the distance between the light-incident surface 210 and the light-emitting surface 10 is greater than 2mm, a large amount of light will not be able to enter the light guide 20, resulting in low light utilization. If the distance between the light-incident surface 210 and the light-emitting surface 10 is less than 0.5mm, the light-emitting surface 10 is too close to the light-incident surface 210, and the light will converge into the light guide 20. Most of the light will be reflected in the same direction, resulting in the light not being effectively diffused, and eventually forming light spots on the diffuser 30. Moreover, when there are multiple light-emitting elements 1, there will be areas between two adjacent light-emitting elements 1 that are not illuminated by the light-emitting element 1, causing these areas to form shadows and have lower brightness than the adjacent areas. Ultimately, this will result in a contrast between light and dark emitted from the diffuser 30, affecting the uniformity of light output.

[0044] See Figure 3In some embodiments, in the second direction, the second distance H between the bottom of the second light-diffusing section 240 and the diffuser 30 is 0.2mm-0.5mm, which can improve display brightness while ensuring display uniformity. The bottom of the second light-diffusing section 240 is, for example, the connection point of two triangular strip structures, the lowest point of the recess formed on the light-emitting surface 220. There is an air gap between the bottom of the second light-diffusing section 240 and the diffuser 30. If the distance is too large, too much light will be lost in the air gap, reducing the light that is finally refracted to the diffuser 30 and reducing the final display brightness; if the distance is too small, the diffuse reflection of the light surface is small, which will reduce the final display uniformity.

[0045] See Figure 2 and Figure 3 In some embodiments, in the second direction, the height of the light guide 20 is greater than or equal to the height of the light-emitting surface 10. The light guide 20 and the light-emitting surface 10 are arranged facing each other along the first direction to ensure that the orthogonal projection of the light-emitting surface 10 along the first direction falls entirely on the light guide 20, and to ensure that more of the light emitted by the light-emitting element 1 enters the interior of the light guide 20, thus guaranteeing the final brightness.

[0046] See Figure 3 In some embodiments, both the first light-blocking element 410 and the second light-blocking element 420 are reflective elements, and both can reflect light into the interior of the light guide element 20. That is, the first light-blocking element 410 and the second light-blocking element 420 are, for example, white or silver-plated PET (polyester) films.

[0047] In another embodiment, the first light leakage prevention element 410 is a reflective element, and the second light leakage prevention element 420 is a light-blocking element. The first light leakage prevention element 410 can reflect light into the interior of the light guide element 20 and finally emit it out of the light guide element 20; the second light leakage prevention element 420 can block the light overflowing from the outside of the light guide element 20 back into the light guide element 20, so that this part of the light can be reflected out of the light guide element 20 again through the first light leakage prevention element 410, thereby increasing the light reflection efficiency of the first light leakage prevention element 410 and improving the display brightness. Among them, the first light leakage prevention element 410 is, for example, a white or silver-plated PET (polyester) film, and the second light leakage prevention element 420 is, for example, a black PET film.

[0048] See Figure 7In some embodiments, multiple light-emitting elements 1 are provided, arranged circumferentially, suitable for lighting devices requiring a ring-shaped interface for light emission. The light guide 20 is a ring-shaped structure surrounding the multiple light-emitting elements 1. Correspondingly, the diffuser 30, the first light leakage prevention element 410, and the second light leakage prevention element 420 are also ring-shaped structures. The ring-shaped structure is located on the outer ring of the multiple light-emitting elements 1, which also ensures that the light emitted by the light-emitting elements 1 enters the light guide 20 more evenly. The light-emitting surfaces 10 of the multiple light-emitting elements 1 all face the light guide 20, and the light emission direction of the light-emitting elements 1 is the first direction, i.e., the radial direction.

[0049] See Figure 3 and Figure 7 In some embodiments, an isolator 50 is included, with an isolator 50 disposed between any two adjacent light-emitting elements 1. The light emitted between two adjacent light-emitting elements 1 may overlap, causing the brightness of that portion to be higher than the brightness of other areas, forming a bright-dark band and resulting in uneven light emission and contrast. The isolator 50 prevents overlapping areas between adjacent light-emitting elements 1, ensuring uniform light brightness.

[0050] See Figure 1 and Figure 8 Another embodiment of this utility model provides an atomizer, which can be applied to humidifiers or aromatherapy diffusers, etc. The atomizer includes a housing 60, an atomizing component, and the aforementioned light-emitting device. An installation space 610 is formed inside the housing 60, and an annular through-hole 620 communicating with the installation space 610 is provided on the housing 60. The housing 60 is, for example, cylindrical. The atomizing component is disposed within the installation space 610; the atomizing component has a mist outlet 710, which is located on the housing 60 and communicates with the outside, allowing the mist generated by the atomizing component to be ejected from the mist outlet 710. The annular through-hole 620 surrounds the mist outlet 710. The light-emitting device is disposed within the installation space 610; a diffuser 30 is located within the annular through-hole 620.

[0051] When the atomizer is working, mist is emitted from the mist outlet 710; simultaneously, the light-emitting element 1 operates, and the light, after being guided and evenly distributed by the light guide component 2, is finally transmitted upward to the diffuser 30, forming a uniform annular light band surrounding the mist outlet 710. The combination of light and mist enhances the aesthetics of the atomizer and the user experience.

[0052] See Figure 1 and Figure 8In some embodiments, the atomizing assembly includes an atomizer (not shown) and a mist outlet channel 720 connected to the atomizer. The atomizer is used to atomize the liquid, and the mist outlet channel 720 is preferably a cylindrical structure. The mist outlet channel 720 extends along a second direction, and the mist outlet 710 is located at the end of the mist outlet channel 720 away from the atomizer. The light guide assembly 2 is disposed around the outer periphery of the mist outlet channel 720, and the light-emitting surface 10 faces the side of the light-emitting element 1 away from the mist outlet channel 720. When the atomizer is working, the mist flows longitudinally along the mist outlet channel 720 and flows out from the mist outlet 710. At the same time, the light-emitting element 1 works, and its light is emitted in the direction away from the mist outlet channel 720. After being guided and homogenized by the light guide assembly 2, the light is finally transmitted upward to the diffuser 30, forming a uniform annular light band around the mist outlet 710.

[0053] Furthermore, multiple light-emitting elements 1 are provided, for example, surrounding the fog outlet channel 720, and the light-emitting surfaces 10 of each light-emitting element 1 are all oriented towards the side away from the fog outlet channel 720. Correspondingly, the light guide 20, the first light leakage prevention element 410, and the second light leakage prevention element 420 are also annular structures and are arranged around the outer periphery of the fog outlet channel 720.

[0054] Furthermore, the housing 60 includes, for example, a base 630 and a top cover 640, with an installation space 610 and an annular through hole 620 formed between the base 630 and the top cover 640, and a mist outlet 710 opened on the top cover 640.
