[0029] Furthermore, in the following detailed description, numerous specific details are set forth for ease of explanation to provide a thorough understanding of embodiments of the present disclosure. However, it will be apparent that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and apparatuses are illustrated to simplify the figures.
[0030] Figures 1 to 6The diagram schematically illustrates the structure of a lamp device and an optical module according to exemplary embodiments of the present disclosure. The optical module, for example, can serve as a component of the lamp device, guiding light from a light source to emit with a desired illumination effect (e.g., a desired intensity distribution or direction) to achieve illumination or signal indication functions. As an example, the lamp device can be mounted in a vehicle as an automotive lamp, for example, including but not limited to headlights such as low beams or high beams, such as integrated high / low beam headlights, or lamps providing other illumination functions such as daytime running lights, position lights, fog lights, brake lights, interior lights, etc. It will be understood that, in addition to the optical module, the lamp device may also include other components not shown, such as a housing accommodating the lighting module, optional light distribution panels, connectors, mounting / positioning elements, etc. The term "vehicle" as used herein can refer to any type of vehicle, such as a motor vehicle, a motorcycle, or any other mobile machine capable of carrying at least one passenger or used for transporting people or goods.
[0031] Figure 1 A schematic diagram of a lamp device 10 according to an exemplary embodiment of the present disclosure is shown. (As shown) Figure 1 As shown, the lamp device 10 includes multiple sets of optical modules. Exemplarily, each set of optical modules includes a first optical element (100a, 100b, 100c). In some embodiments, the optical assembly further includes a second optical element (200a, 200b, 200c). The first light-emitting portion of the first optical element and the second light-emitting portion of the second optical element form a predetermined optical pattern.
[0032] In some embodiments, such as Figure 1 As shown, the first optical element (100a, 100b, 100c) and the second optical element (200a, 200b, 200c) can correspond one-to-one. When viewed from the light emission direction of the second optical element, the predetermined optical pattern formed by the first light-emitting part of the first optical element and the second light-emitting part of the second optical element is continuous. For example, it can form a continuous spiral, wave, or sawtooth shape, or other optical patterns with three-dimensional perspective.
[0033] Figure 2 A first optical element of optical unit 100a in an optical module according to an exemplary embodiment of the present disclosure is shown. In some embodiments, such as Figure 2 The first optical element 100a shown includes a first light-emitting part 120, which is configured as a polyhedron with at least four light-emitting surfaces. For example, the first light-emitting part 120 has at least light-emitting surfaces 121, 122, 123 and 124, and light can be emitted from each light-emitting surface of the polyhedron, so the three-dimensional structure of the polyhedron can be observed from the outside.
[0034] Figure 2The first optical element 100a is also shown to include a first light guide portion 130, which is configured to guide light from the light source toward the first light emitting portion 120. In some embodiments, the first optical element 100a is fixed to the housing of the lamp device 10 via the first light guide portion 130.
[0035] Figure 3 This is a schematic diagram illustrating an optical module according to an exemplary embodiment of the present disclosure. Figure 4 A cross-sectional view schematically illustrating the structure of an optical module according to an exemplary embodiment of the present disclosure is shown. Figure 3 and Figure 4 As shown, the optical module consists of a first optical element 100a and a second optical element 200a. Light from the first optical element 200a propagates in 100a and exits from its first light-emitting portion 120, while light from the second light source 20b propagates in 200a and exits from its light-emitting surface. Although... Figure 4 As shown, the first optical element 100a and the second optical element 200a are not on the same plane in terms of structure, such as... Figure 3 As shown, the first optical element 100a and the second optical element 200a are visually continuous at 150a, so that multiple sets of optical modules as described in the embodiments of this disclosure can form a continuous three-dimensional optical pattern. The materials used for the first optical element 100a and the second optical element 200a can be selected according to actual needs, such as being made of glass, resin or plastic materials, for example, PMMA (polymethyl methacrylate) or polycarbonate.
[0036] In some embodiments, such as Figure 4 As shown, the internal scattering structure of the first light-emitting portion 120 of the first optical element 100a disperses the light from the first light source 20a, so that when each light-emitting surface of the light-emitting portion 120 is observed from different external angles, all light-emitting surfaces are illuminated and the emitted light is more uniform. In other embodiments, at least one light-emitting surface of the first light-emitting portion 120 has a microstructure 128 to improve the utilization rate of light from the first light source 20a. For example, the microstructure 128 may be a ground glass structure or a prism structure. In some embodiments, the second optical element 200 may have a collimating portion to make the light emitted by the second optical element 200 uniform.
[0037] Figure 5 A schematic diagram of an optical element 300 in an optical module according to another exemplary embodiment of the present disclosure is shown. Figure 5 As shown, the first optical element 300 includes a first light guide 330 and a first light emitting part 320, wherein the optics from the first light source can be emitted from multiple light emitting surfaces 321, 322, 323, and 324 respectively to form a three-dimensional pattern effect.
[0038] Figure 6 A schematic diagram of an optical unit in an optical module according to another exemplary embodiment of the present disclosure is shown. (See diagram below.) Figure 6 As shown, in some embodiments, a fixing part 340 is provided at one end of the first light-emitting part 320 opposite to the first light-guiding part 330, so that the first light element 300 can be fixed to the housing from both ends of the first light-guiding part 330 and the fixing part 340, and the structure is more stable without affecting the optical effect.
[0039] Although Figures 1 to 4 An example is shown where an optical module includes multiple corresponding first and second optical elements to form a continuous three-dimensional optical pattern. However, it should be understood that the technical solutions disclosed herein are not limited to this. In some embodiments, the optical unit may have only multiple first optical elements, wherein the first light-emitting portions of the multiple first optical elements have different mounting angles, so that the multiple optical elements can also be combined to form a predetermined optical pattern. In other embodiments, the number of first and second optical elements is not one-to-one, as long as a predetermined optical pattern can be formed.
[0040] This disclosure also provides a motor vehicle that includes the optical components or lighting devices described in any embodiment of this disclosure. The vehicle has the advantages of the aforementioned lighting devices. The term "vehicle" as used herein can refer to any type of vehicle, such as a car, motorcycle, or any other mobile machine capable of carrying at least one passenger or used for transporting people or goods.
[0041] Although this disclosure has been described in conjunction with the accompanying drawings, the embodiments disclosed in the drawings are intended to illustrate preferred embodiments of this disclosure and should not be construed as limiting the disclosure. The dimensions in the drawings are merely illustrative and should not be construed as limiting the disclosure.
[0042] While some embodiments of the general concept of this disclosure have been shown and described, those skilled in the art will understand that changes may be made to these embodiments without departing from the principles and spirit of the general concept of this disclosure, the scope of which is defined by the claims and their equivalents.
