Description

Technical Field

[0001] The present invention relates to the generation of lighting effects, and more particularly to an apparatus for generating starlight lighting effects. Background Technology

[0002] Using colored lights on speakers creates a vibrant light show that complements music, enhancing the user's audiovisual experience. For example, LED lights of various colors can emit hues such as red, green, and blue, and people often use the visual effects of LED lights to create a rich and colorful atmosphere.

[0003] However, due to limitations in the number and size of LEDs, the colors presented may not be rich or vibrant enough, and uneven color mixing may even lead to a rough display effect, making viewers feel that the quality is poor and therefore not visually satisfactory.

[0004] Therefore, there is a need for a solution to produce lighting effects that can present clearer and more vibrant colors, and can also create a more uniform and softer lighting texture through color mixing, while keeping the product cost low. Summary of the Invention

[0005] In order to enable users to enjoy rich and colorful, evenly mixed, high-quality lighting effects while listening to audio, this disclosure provides a device and method for generating starlight lighting effects. The device and method are combined with a multi-color light source set in the speaker to produce a starlight lighting effect with clearer and more brilliant colors and more even and soft color mixing. The product is also inexpensive and of high quality.

[0006] According to one aspect of this disclosure, an apparatus for generating a starburst lighting effect is provided. The apparatus may include at least one multi-color light source and at least one light guide lens. The at least one multi-color light source is arranged to emit multiple lights, wherein the multiple lights may include at least two colors. The at least one light guide lens is disposed in front of the at least one multi-color light source, and its main body is constructed as a column to conduct the multiple lights through the at least one light guide lens via total internal reflection, thereby mixing the multiple lights into a mixed-color light. The front portion of the light guide lens is constructed as an enlarged flared platform to diffuse the mixed-color light.

[0007] According to another aspect of this disclosure, a method for producing a starburst lighting effect is provided. The method includes arranging at least one multi-color light source to emit a plurality of lights, wherein the plurality of lights may include at least two colors of light. The method further includes arranging at least one light guide lens in front of the at least one multi-color light source, and constructing the main body of the at least one light guide lens as a column, such that the plurality of lights are conducted through the at least one light guide lens by total internal reflection, thereby mixing the plurality of lights into a mixed-color light. The front portion of the at least one light guide lens is constructed as an enlarged flared platform to diffuse the mixed-color light.

[0008] Furthermore, the main body of at least one light guide lens may include a diffuser lens portion configured to diffuse multiple lights, thereby uniformly mixing them into mixed-color light. The diffuser lens portion is configured to incorporate a certain amount of diffusing powder into its internal transparent material.

[0009] Furthermore, the front portion of at least one light guide lens may include a reflective lens portion, which is fixed to the front of the main body portion and fully engaged therewith.

[0010] Furthermore, the inner periphery of the reflecting lens portion includes a reflective surface, and the reflective surface may be coated with a reflective coating to reflect the mixed-color light over a wider range. The reflective surface may include reflective structures, such as minute curved surfaces, or other regular or irregular uneven structures, to reflect the mixed-color light divergently in more directions over a wider range.

[0011] Furthermore, the device for generating a starlight effect provided in this disclosure also includes a front grille, which can replace the front panel of the speaker and is arranged in front of at least one light guide lens so that the reflected mixed light passes through the gaps in the front grille to produce a starlight effect. Attached Figure Description

[0012] These and / or other features, aspects, and advantages of the invention will be better understood after reading the following detailed description with reference to the accompanying drawings, throughout which like characters represent like parts, wherein:

[0013] Figure 1 A schematic diagram of a device for generating a starlight effect according to one or more embodiments of the present disclosure is shown; and

[0014] Figure 2 A flowchart illustrating a method for generating a starburst lighting effect according to one or more embodiments of the present disclosure is shown schematically. Detailed Implementation

[0015] Various embodiments are described below for illustrative purposes, but are not intended to be exhaustive or limiting of the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.

[0016] Figure 1 A schematic diagram 100 illustrates a structure of an apparatus for generating a starburst lighting effect according to one or more embodiments of the present disclosure. Figure 1 The image shows an example of an interior scene within a portion of a speaker enclosure, in which the apparatus for generating a starburst lighting effect, as provided in this disclosure, is arranged.

[0017] The apparatus for producing a starburst lighting effect may include at least one light source. This at least one light source may be a multi-color light source capable of emitting two or more colors of light. In some examples, such a multi-color light source may be a light source module composed of multiple monochromatic LEDs. For example, the multi-color light source may also include, but is not limited to, LEDs such as warm and cool white LEDs, RGB LEDs, and / or RGBW LEDs. Furthermore, the multi-color light source may also be, for example, a monochromatic or multi-color laser light source.

[0018] The multi-color light source described in this disclosure uses the RGB LED light source 110 as an example; other multi-color light sources can be used similarly. For example, the RGB LED can be placed on a PCB inside the speaker housing and powered by a power supply to emit light. The RGB LED light source 110 can emit multiple lights, such as... Figure 1 As shown, the RGB LED light source 110 can emit light including red light 112, green light 114 and / or blue light 116.

[0019] like Figure 1 As shown, the device for generating a starburst lighting effect also includes a starburst lighting structure 120. At least one light guide lens 130 is disposed within this starburst lighting structure 120. The at least one light guide lens 130 can be positioned in front of at least one RGB LED light source 110. Figure 1 In the example shown, the main body of the light guide lens 130 is constructed as an elongated column, so that the light emitted by the RGB LED can be transmitted along its length in the light guide lens.

[0020] The light guide lens 130 can be constructed as a lens made of transparent material. The main body of the light guide lens 130 can be a column with smooth side surfaces, used to guide the light emitted by the RGB LED light source 110 from, for example, the PCB to the front panel of the speaker or other light-emitting position. For example, the light emitted by the RGB LED light source 110 can enter from one end of the light guide lens 130, and can be conducted along the elongated column of the light guide lens 130 according to total internal reflection and exit from the other end.

[0021] The light guide lens 130 can be made of a material with a refractive index much higher than that of its outer sheath, allowing RGB LED light entering the light guide lens to be trapped within it for total internal reflection without passing through the lens 130, thus guiding it tortuously along the length of the light guide lens 130's column. The light guide lens 130 needs to have excellent light guiding properties. For example, it can be made of materials such as PC or PMMA to achieve good light conductivity. Alternatively, it can be made of materials such as optical glass. For instance, it can be made of quartz glass to reduce impurities and improve the structural uniformity within the lens 130, thereby enhancing light transmission.

[0022] Furthermore, the device for generating the starlight effect may also include a front grille 140. The front grille 140 may be configured to include a plurality of gaps. When, for example, the device for generating the starlight effect is used in a speaker, the front grille 140 may replace the front panel of the speaker to protect the internal structure of the speaker. The front grille 140 of the speaker may be made of a mesh material such as metal, plastic, and / or fiberglass. The front grille 140 may be configured such that light transmitted and emitted from inside the speaker via the light guide lens 130 in the starlight structure can further pass through the gaps in the front grille 140 to be visible to the user.

[0023] When at least one RGB LED light source 110 arranged inside the speaker emits red light 112, green light 114, and / or blue light 116, the light can be conducted through the light guide lens 130 by total internal reflection. Since the front grille 140 has a structure in which the grille and its gaps are interwoven, these lights can pass through the gaps on the front grille 140 to form a starry lighting effect.

[0024] However, for light spots emitted by the RGB LED light source 110 that directly mix and image colors through conduction, users may see inconsistent colors at different viewing angles. For example, for the same light spot, a user might see a red light spot from one angle, and a green light spot from a slightly different angle, or even see a light spot that is partially reddish and partially greenish simultaneously. Such a visual effect may be strange and appear crude. In addition, because the grille on the front grille 140 may block some light spots, these light spots cannot pass through the front grille and cannot be seen by the user.

[0025] Therefore, in one or more embodiments of this disclosure, the main body of the light guide lens 130 may further include a diffuser lens portion 150. This diffuser lens portion 150 may be configured to diffuse multiple light sources incident upon it at one end, such that these light sources are uniformly mixed 152 into a uniformly colored mixed light source 154. For example... Figure 1 In the example shown, the red light 112, green light 114, and / or blue light 116 emitted by the RGB LED light source 110 can be uniformly mixed 152 into a mixed-color light 154 by the diffuser lens section 150. In one case, the mixed-color light 154, resulting from the mixing of the three colors of light emitted by the RGB LED light source 110 (red 112, green 114, and blue 116) by the diffuser lens section 150, can be transformed into, for example, white light. Furthermore, the RGB LED light source 110 can also mix 152 to produce other colors of light; for example, mixing the red light 112 and blue light 116 emitted by the RGB LED light source 110 can produce, for example, purple light, and so on. Therefore, in terms of color mixing of light in the light guide lens, the light from a multi-color light source can possess diverse characteristics.

[0026] Additionally or alternatively, to achieve more uniform color mixing of the light, a certain amount of diffusing powder (not shown) can be incorporated into the transparent material of the diffuser lens section 150. The physical entity of the diffusing powder can be, for example, a fine white powder, and the size, shape, and distribution of the particles can be precisely controlled through advanced manufacturing processes during injection molding into the diffuser lens section 150. Therefore, the diffusing powder can be processed and then incorporated into the diffuser lens section 150 during injection molding. Furthermore, the characteristics of the diffusing powder and the diffuser lens section 150 can be adjusted as needed to adjust the scattering angle, color of the scattered light, and scattering efficiency of the originally red light 112, green light 114, and / or blue light 116 from the RGB LED light source, achieving uniform color mixing and obtaining a vibrant color-mixed light effect 154, thus meeting the personalized needs of speaker design.

[0027] When illuminated by light, the diffuser powder causes light to scatter, breaking up the originally straight-line propagating light and scattering it in various directions. In one example, for the RGB LED light entering the diffuser lens section 150 and the mixed-color light 154, the diffuser powder can make it diffuse and diffuse, changing the original propagation path of the light. Therefore, when the light passes through the diffuser lens section 150 containing the diffuser powder, due to the multi-angle scattering of the light, the originally sharp and dazzling light can become soft and pleasant, and the point light source can be transformed into a surface light source. Those light points that might be blocked can at least partially see through the gaps in the front grille and be seen by the user, thus making the overall lighting effect more uniform and beautiful. Moreover, while ensuring the brightness of the light, it avoids the potential risk of damaging the user's eyes due to the central area of ​​the LED light being too bright.

[0028] like Figure 1 As shown, the front portion of the light guide lens 130 can be configured such that its cross-sectional diameter gradually increases along the length of the light guide lens, thereby giving the front portion of the light guide lens 130 an enlarged flared shape. This design allows the mixed light that passes through the main body of the light guide lens 130 by total internal reflection to diverge outwards from the flared front portion after entering it, thus dispersing the uniformly mixed light over a larger area and achieving a larger area lighting effect.

[0029] In one or more embodiments of this disclosure, the front portion of the light guide lens 130 may further include a reflective lens portion 160. This reflective lens portion may be formed in front of the main body portion (or the diffuser lens portion 150) of the light guide lens 130. For example, the reflective lens portion 160 of the light guide lens 130 may be configured as a cone with its tip whitishly removed. More specifically, the reflective lens portion 160 of the light guide lens 130 may be configured as a laterally placed platform, the central axis of symmetry of which coincides with the central axis of symmetry of the main body portion, and the smaller cross-section of the platform is the same size as and fully engaged with the cross-section of the cylindrical portion of the main body portion. Further, for example, the reflective lens portion 160 may be fixed in front of the diffuser lens portion 150 of the light guide lens 130, fully engaged with the diffuser lens portion 150. For example, the reflective lens portion 160 and the diffuser lens portion 150 may be jointly configured as a light guide lens 130 having an expanded flared shape.

[0030] like Figure 1 As shown, viewed from the lateral direction, the inclined inner side of the reflective lens portion 160 also includes a reflective surface that can reflect the uniformly mixed color light 154 over a larger area.

[0031] Additionally or alternatively, the reflective surface around the side of the reflective lens portion 160 may include a reflective coating. For example, the reflective coating may be a thin metal film formed on the inner surface of the reflective lens portion, which can reflect light in large quantities, improving the brightness and focusing effect of the light source. For example, the reflective coating may be at least one metal layer applied to the inner surface of the reflective lens portion, such as a coating of reflective materials like aluminum plating or copper plating, thereby enabling the reflective surface around the inner side of the reflective lens portion 160 to reflect light, making the light more focused and improving the brightness and imaging effect of the LED light, especially when using a speaker equipped with such lighting effects in dimly lit scenes or in scenes where the surrounding environment is not easily noticeable.

[0032] Furthermore, the inner periphery or inner wall of the reflecting lens portion 160 may also include a reflective structure, which can be configured to reflect the mixed-color light 154 in multiple directions. For example, the reflective structure 162 of the reflective surface surrounding the inner periphery of the reflecting lens portion 160 may include minute curved surface structures formed thereon, such as... Figure 1 As shown. Furthermore, the reflective structure 162 surrounding the inner side of the reflective lens portion 160 may also include other minute irregular structures. For example, these reflective structures 162 may be regular or irregular to diffusely reflect the uniformly mixed color light 154 over a wider range in more directions. Such a light spot capable of diverging over a wider range can display a light show in a more nuanced ambient light pattern without being limited by the small size of the light spot produced by the lens size. This allows the uniformly mixed color light 154 to at least partially pass through the gaps in the front grille of the speaker, producing a starlight-like imaging effect 170, enabling the user to view a clearer and more uniformly colored starlight effect.

[0033] Figure 2 A flowchart 200 schematically illustrates a method for generating a starburst lighting effect according to one or more embodiments of the present disclosure. The method for generating a starburst lighting effect includes the following steps:

[0034] In step S210, at least one multi-color light source is arranged, for example, inside a speaker enclosure, to emit light of at least two colors onto the front panel. Taking an RGB LED light source as an example, the RGB LED light source can be placed on a PCB inside the speaker enclosure and powered by a power supply to emit light. The RGB LED light source can emit multiple lights; for example, it can emit red, green, and / or blue light.

[0035] In step S220, the main body of the light guide lens is constructed as an elongated column, allowing light to be conducted by total internal reflection and travel along the length of the column within the light guide lens. The columnar portion of the light guide lens may include a diffuser lens portion. During the injection molding of the diffuser lens portion, a certain amount of diffusing powder can be incorporated into its transparent material. The size, shape, and distribution of the diffusing powder particles can be precisely controlled through advanced manufacturing processes, and the characteristics of the diffusing powder and the diffuser lens portion can be adjusted as needed. This allows for adjustments to the angle of light scattering, the color of the scattered light, and the scattering efficiency within the diffuser lens portion, thereby meeting personalized lighting effect requirements. Therefore, after the light interacts with the diffusing powder in the diffuser lens portion, it can more uniformly mix to form a mixed-color light, which is then conducted along the diffuser lens portion into the front of the light guide lens.

[0036] In step S230, the front part of the light guide lens can be configured such that its cross-sectional diameter gradually increases along the length of the light guide lens, thereby forming an expanded horn shape, so that the mixed light can be emitted from the horn to a larger area, resulting in a larger area of ​​light effect.

[0037] Alternatively or alternatively, the front portion can be configured as a reflective lens section, and this reflective lens section can be shaped as, for example, a horizontally placed platform. The smaller cross-section of this platform matches and fully engages with the cross-section of the elongated column of the main body of the light guide lens, thus fixing it in front of the main body. A reflective surface can be provided around the inner side of the reflective lens section. For example, a thin metal film can be formed on the surface around the inner side of the reflective lens section, or a reflective coating, such as aluminum plating or copper plating, can be applied, so that the mixed-color light within the reflective lens section can be reflected over a wider range by the reflective coating.

[0038] Furthermore, the inner periphery or inner wall of the reflective lens portion at the front of the light guide lens can be constructed with a regular or irregular reflective structure to reflect the mixed-color light in multiple directions. For example, a tiny curved surface structure can be formed around the inner periphery of the reflective lens portion. In addition, the reflective structure can also include other tiny concave and convex structures to diffusely reflect the mixed-color light over a wider range in more directions.

[0039] Next, in step S240, at least one light guide lens can be arranged in the starlight structure, in conjunction with the design and manufacture of at least one multi-color light source, so that the at least one light guide lens constructed in the previous steps is placed in front of at least one multi-color light source. For example, when RGB LED light sources emit red, green, and / or blue light, these lights can enter one end of the light guide lens and be transmitted by total internal reflection along the length of the light guide lens, and further be uniformly mixed into mixed-color light through diffusion.

[0040] Finally, in step S250, the front panel of the speaker can be configured as a front grille with gaps. The color-mixed light, which is uniformly mixed in the diffuser lens section, can be reflected in multiple directions toward the front grille through the reflector lens section. Therefore, the color-mixed light can form a larger light spot and, through the gaps in the front grille, produce a starlight-like twinkling light effect.

[0041] The method for generating a starburst lighting effect provided by this disclosure, through the above steps, allows the light emitted by a multi-color light source to be transmitted via total internal reflection through a light guide lens. At the same time, the multi-color light is first scattered and diffused by the diffuser powder in the diffuser lens section and uniformly mixed into a mixed-color light. Then, the mixed-color light is reflected divergently to the front grille of the speaker front panel in the reflector lens section, so that the user can see a starburst lighting effect with a larger range of light spots, uniform beauty and brilliant colors through the front grille of the speaker.

[0042] The method and apparatus for generating starlight effects provided in this disclosure can mix red, green, and / or blue light emitted from RGB LED light sources in a very uniform manner. This uniformly mixed visible light does not produce excessively high central brightness from the LEDs, thus avoiding the risk of eye damage for viewers. The method and apparatus for generating starlight effects provided in this disclosure can display light shows in subtle, imperceptible environmental modes. By utilizing a reflective coating arranged in a light guide lens, the mixed light can produce a larger range of light spots or patches, even larger than the lens itself. Because these larger light spots are easier to see, fewer light sources can be used to create the starlight effect, making the imaging more economical and cost-effective.
