Description

Technical Field

[0001] This utility model relates to the field of automotive component technology, specifically to an ambient light with an adjustable luminous area. Background Technology

[0002] Conventional automotive interior ambient lighting (especially static ambient lighting) is basically fixed, meaning the illuminated or glowing area is constant, creating a stable overall lighting effect. Dynamic ambient lighting, on the other hand, achieves its effect by controlling the timing of light emission from light sources placed in different locations, such as breathing color changes or dynamic flowing water effects. This type of conventional dynamic effect is mature and widespread, lacking innovation in user interaction and emotional expression. Utility Model Content

[0003] The purpose of this invention is to provide an ambient light with a more flexible light-emitting area that can change its illumination.

[0004] The ambient light with adjustable luminous area provided by this utility model may include: a bracket forming a plurality of recessed spaces arranged side by side, each of the recessed spaces having an opening on the same side; a plurality of light guide strips respectively disposed in one of the recessed spaces, such that the plurality of light guide strips are arranged side by side on the bracket; a plurality of light source modules disposed on the bracket, each of the light source modules being configured with one light guide strip, each of the light source modules including a plurality of LEDs, the plurality of LEDs respectively projecting light into the plurality of light guide strips for conduction; a controller electrically connected to the plurality of light source modules for controlling whether each of the LEDs in the plurality of light source modules emits light and the timing of the light emission; a lampshade fixed to the side of the bracket with the opening, and simultaneously fixing the plurality of light guide strips to the bracket; wherein, the plurality of light guide strips have different light emission angles in the radial direction, and the light shines through the plurality of light guide strips onto different areas of the irradiated object.

[0005] Preferably, one side of each of the plurality of light guide strips has a reflective surface, and the other side opposite the reflective surface has a light-emitting surface. The angle between the reflective surface and the horizontal plane is different for each light guide strip. When the light guide strip is disposed in the recessed space, the reflective surface is located inside the recessed space, and the light-emitting surface is located outside the recessed space. Accordingly, light transmitted within the light guide strip can be reflected off the light guide strip by reflective surfaces at different angles, thereby illuminating different areas.

[0006] In one embodiment of this invention, the reflective surface can be a plane, and a plurality of tiny protrusions for reflecting light can be formed on this plane. The included angles of the plurality of light guide strips gradually decrease or gradually increase from one side to the other along the arrangement direction of the plurality of light guide strips. Accordingly, the light and shadow areas illuminating the object through the reflective surface have different widths.

[0007] In one embodiment of the present invention, the controller can control a plurality of LEDs to emit light sequentially, thereby causing a plurality of light guide strips to emit light sequentially from one side to the other along their arrangement direction.

[0008] Preferably, the outer surface of the lampshade may have raised or recessed patterns or a coating, through which light emitted from the light guide strip is emitted to the outside of the lampshade. This creates a unique and captivating lighting effect.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. This invention can achieve dynamic effects at a low cost, requiring only a minimum of three light guides and at least three light source modules to clearly achieve a dynamic waterfall effect in the horizontal direction. Furthermore, the entire ambient lighting assembly is highly flexible and adaptable; the number of light guides and the number of light source modules installed can be increased or decreased based on different needs to achieve dynamic effects of varying precision.

[0010] 2. This utility model can achieve a color-blocking effect at a lower cost. That is, when each light source module is individually controlled to light up LEDs of different colors, the illuminated area can achieve color-blocking effects (i.e., different colors are mixed together) or gradient color effects.

[0011] 3. This utility model can effectively achieve different illumination widths by replacing the light guide strips with different illumination angles, and has a good adjustment effect for the use of ambient lights in different positions in the car, which can adapt to the illumination needs of different areas.

[0012] 4. Compared with conventional products, this utility model is more compact and simple in terms of space, requires less height space, and can achieve simple dynamic effects without a large height space. Attached Figure Description

Detailed Implementation

[0015] To facilitate understanding of this utility model, it will be described in detail below with reference to the accompanying drawings and embodiments. The drawings show some, but not all, embodiments of this utility model. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable those skilled in the art to gain a more thorough and comprehensive understanding of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive changes are within the scope of protection of this utility model.

[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0017] like Figures 1 to 4 As shown, the ambient light with adjustable luminous area provided by this utility model includes a bracket 10, a light guide strip 20, a light source module 30, a controller 40, and a lampshade 50. The bracket 10 has a plurality of recessed spaces 101 arranged side-by-side, each recessed space 101 having an opening 102 on the same side of the bracket 10. More specifically, the bracket 10 can be injection molded from plastic material or extruded from metal material into a long strip shape, and a plurality of parallel recessed spaces 101 with a "U"-shaped cross-section are formed on one side of this long strip shape. The "U"-shaped notch of the recessed space 101 is the opening 102. The bracket 10 is used for installation at an appropriate location on a vehicle interior trim 70.

[0018] The light guide strips 20 are formed into elongated strips using a material with excellent light guiding properties, and their number corresponds to the number of recessed spaces 101 in the bracket 10. In order to achieve a good ambient lighting effect, the preferred embodiment of this utility model has at least three recessed spaces 101 formed in the bracket 10 and at least three light guide strips 20, each of which is respectively disposed in a recessed space 101. The number of light guide strips 20 and recessed spaces 101 can also be set to more than three according to the actual needs of the luminous atmosphere.

[0019] A light source module 30 is disposed on the side of the bracket 10 and electrically connected to the controller 40. The light source module 30 includes a plurality of LEDs 301. Each light source module 30 is coupled to a light guide strip 20 and the LEDs 301 are aligned with the ends of the light guide strip 20. The controller 40 is used to control the circuit of the light source module 30, thereby controlling whether the LEDs 301 emit light and the timing of the light emission. When the LEDs 301 are powered on and emit light, light enters the light guide strip 20 from the ends of the light guide strip 20 and is conducted through it, and finally emits light from the light-emitting surface 202 of the light guide strip 20 to form a light emission effect. Preferably, the controller 40 controls the plurality of LEDs 301 to emit light in sequence, so that the plurality of light guide strips 20 emit light in sequence from one side to the other along their arrangement direction.

[0020] Each of the plurality of light guide strips 20 has a different light emission angle in the radial direction. Light passes through the plurality of light guide strips 20 and illuminates different areas of the illuminated object 60 to create a unique visual atmosphere. More specifically, each light guide strip 20 has a planar reflective surface 201 on one side and an arc-shaped light emission surface 202 on the other side. A plurality of small, reflective teeth (not shown in the figure) can be formed on the planar reflective surface 201 to reflect light. When each light guide strip 20 is positioned within a recessed space 101, each reflective surface 201 is located on the inner side of the recessed space 101 (i.e., the side opposite to the opening 102), and the light emission surface 202 is located on the outer side of the recessed space 101 (i.e., the side opposite to the opening 102). Furthermore, the angle θ between the reflective surface 201 and the horizontal plane is different for each light guide strip 20; for example… Figure 3 The first reflective surface 201A of the first light guide strip 20A shown can coincide with the horizontal plane without any angle or have a first angle θ1. The second reflective surface 201B of the second light guide strip 20B has a second angle θ2 with the horizontal plane. The third reflective surface 201C of the third light guide strip 20C has a third angle θ3 with the horizontal plane. The second angle θ2 is greater than the first angle θ1, and the third angle θ3 is greater than the second angle θ2. That is, along the arrangement direction from the first light guide strip 20A to the third light guide strip 20C, the angle from the first angle θ1 to the third angle θ3 gradually increases, or along the arrangement direction from the third light guide strip 20C to the first light guide strip 20A, the angle from the third angle θ3 to the first angle θ1 gradually decreases. Accordingly, the light transmitted in the light guide strip 20 is reflected by the reflective surface 201 and emitted from the light-emitting surface 202. The area of ​​the light emitted from each light guide strip 20 that illuminates the surface of the irradiated object 60 is different.

[0021] The lampshade 50 is used to fix the bracket 10 to the side with the opening 102, and at the same time fixes each light guide strip 20 to the bracket 10. More specifically, the lampshade 50 can be formed with an inverted "U" shape in the transverse cross section, and the lampshade 50 covers the outside of the bracket 10. After covering, the contact surfaces of the lampshade 50 and the bracket 10 can be fixed by adhesive or by fixing structures such as hooks; the fixing structures can have various forms and are known technologies, so their detailed description is omitted; accordingly, the light emitted through the light-emitting surface 202 of the light guide strip 20 is scattered by the lampshade 50 to form a soft light effect. Furthermore, this utility model can also form a plurality of protruding or recessed patterns 501 (such as...) on the outer surface of the lampshade 50. Figure 5 (as shown), or a coating is formed on the outer surface of the lampshade 50, so that light is refracted when it passes through the pattern 501 or the coating before exiting the lampshade 50, so as to produce a more dazzling visual effect.

[0022] By utilizing the aforementioned ambient light structure of this invention, different light-emitting areas can be varied on the surface of the illuminated object 60 when different numbers of light guide strips 20 are controlled to emit light; for example... Figure 6 The image shown is an illustration of the illumination effect when all three light guides 20 are lit. Figure 7 The image shown is an illustration of the illumination effect when two of the three light guides 20 of an ambient light are lit. Figure 8 This is an illustration of the illumination effect when one of the three light guides 20 of an ambient light is lit.

[0023] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various changes and modifications without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
