[0035] Please also refer to Figures 1 to 4 . Figure 1 、 Figure 2 They are respectively an exploded schematic diagram and an assembled schematic diagram of the first embodiment of the lamp with a color-changing function of the present application. Figure 3 、 Figure 4 They are respectively an operation schematic diagram and an application schematic diagram of the first embodiment of the lamp with color-changing function of the present application.
[0036] As shown in the figure, the color-changing lamp L of the present application is preferably applicable to headlights of motor vehicles such as cars and motorcycles. The color-changing lamp L of the present application mainly includes a lamp housing module 10, a light-emitting module 20, a light guide 30 and a color adjustment module 40.
[0037] The lamp housing module 10 can be composed of a first lamp housing 11 and a second lamp housing 12. The first lamp housing 11 and the second lamp housing 12 can be made of a metal material such as aluminum or an aluminum alloy, or one of the first lamp housing 11 and the second lamp housing 12 can be made of a metal material and the other can be made of a plastic material. The lamp housing module 10 has a light outlet 101 at one end and a supporting portion 102 inside. Preferably, in an embodiment, the supporting portion 102 is disposed on the second lamp housing 12. The supporting portion 102 can be a plane with multiple fixing structures or a groove with multiple fixing structures.
[0038] The light-emitting module 20 is arranged on the supporting portion 102. The light-emitting module 20 may include a circuit board and one or more light-emitting units arranged on the circuit board; wherein the circuit board has relevant circuits corresponding to light emission, and the light-emitting unit may be, for example, a light-emitting diode, which is a component well known or commonly used by technicians in the technical field to which this application belongs, and will not be described in detail here. The light-emitting module 20 has a light-emitting surface 21; wherein the light-emitting surface 21 is an imaginary plane from which the light-emitting diode emits light. The light-emitting module 20 is configured to emit light 22 having a first chromaticity. For example, the light 22 of the first chromaticity may be, for example, white light.
[0039] It is worth mentioning that the supporting surface of the supporting portion 102 and the light-emitting surface 21 are not parallel to the axis of the light-emitting port 101, that is, the light emitted by the light-emitting surface 21 has an angle or is perpendicular to the light-emitting port 101 (or the optical axis of the light), so that the light guide 30 mentioned later can properly guide the light to the light-emitting port 101.
[0040] The light guide 30 can be a reflective member (or reflective cover) made of plastic or other suitable materials, which is arranged inside the lamp housing module 10. Preferably, the light guide 30 is a semi-elliptical cover. The light guide 30 is arranged on the light emitting module 20 in a direction perpendicular to the light emitting surface 21. Incidentally, the inner surface of the light guide 30 is set to a surface that is easy to reflect or fully reflect, which can be a smooth surface or a surface with an appropriate microstructure. Figure 4As shown, the light guide 30 is configured to guide light to the light outlet 101; that is, the shape of the inner surface of the light guide 30 can guide light to the light outlet 101, and there is no special limitation here.
[0041] Among them, the color adjustment module 40 is arranged inside the lamp housing module 10. The color adjustment module 40 has a driving module 41 and a color adjustment unit 42. The driving module 41 is configured to make the color adjustment unit 42 selectively located between the light emitting surface 21 and the light guide 30 or away from the light emitting surface 21 and the light guide 30, so that when the color adjustment unit 42 is located between the light emitting surface 21 and the light guide 30, the light is converted into a second chromaticity after passing through the color adjustment unit 42. The second chromaticity is, for example, yellow light and is different from the first chromaticity, for example, white light. Therefore, in use, when the lamp L with a color changing function of the present application is desired to emit light 22 of the first chromaticity of white light, the color adjustment unit 42 can be left (not located) between the light emitting surface 21 and the light guide 30; that is, the color adjustment unit 42 does not block the light emitting surface 21. Furthermore, when the color-changing lamp L of the present application is intended to emit yellow light of the second chromaticity 23, the color-changing unit 42 can be positioned between the light-emitting surface 21 and the light guide 30; that is, the color-changing unit 42 shields the light-emitting surface 21. The conversion of light passing through or through the color-changing unit 42 into light of another chromaticity is a well-known or commonly used technique by those skilled in the art and will not be further elaborated upon here.
[0042] like Figure 3 As shown, in this embodiment, the driving module 41 may be a stepper motor or a servo motor. The color adjustment unit 42 may include a linkage shaft 421 and a color adjustment plate 422. One end of the linkage shaft 421 is connected to the rotating shaft of the driving module 41, or the linkage shaft 421 is the rotating shaft of the driving module 41, or the linkage shaft 421 and the rotating shaft of the driving module 41 are linked by components such as transmission belts and gears. The axis of the linkage shaft 421 is parallel to the light emitting surface 21, and the driving module 41 drives the linkage shaft 421 to rotate. The color adjustment plate 422 is arranged at the other end of the linkage shaft 421, and the color adjustment plate 422 is located on one side of the axis of the linkage shaft 421. With this configuration, when the driving module 41 drives the linkage shaft 421 to rotate, for example, 180 degrees, the color matching plate 422 can be converted from not blocking the light-emitting surface 21 to blocking the light-emitting surface 21; conversely, when the driving module 41 drives the linkage shaft 421 to rotate, for example, 180 degrees in the opposite direction, the color matching plate 422 can be converted from blocking the light-emitting surface 21 to not blocking the light-emitting surface 21; wherein, 180 degrees is only an example, and the angle is set to enable the color matching unit 42 to block or not block the light-emitting surface 21, so no special limitation is made here.
[0043] In addition, the lamp L with a color-changing function may include a lens unit 51 and a fixing ring 52. The lens unit 51 is located at the light outlet 101. The fixing ring 52 fixes the lens unit 51 to the light outlet 101; wherein, the lens unit 51 and the fixing ring 52 are well known to those skilled in the art and will not be described in detail here. Optionally, the lamp L with a color-changing function includes a high and low beam switching device 60. The high and low beam switching device 60 is arranged inside the lamp housing module 10 and is located between the light outlet 101 and the light-emitting module 20. Of course, the lamp L with a color-changing function also includes components such as a circuit module for controlling whether to emit light, a port for electrically connecting to a car, heat dissipation components and fans related to heat dissipation, etc., which are well known to those skilled in the art and will not be described in detail here.
[0044] See also Figure 5 、 Figure 6 , which are respectively a schematic structural diagram and an operational diagram of the second embodiment of the color-changing lamp of the present application. In this embodiment, components with the same reference numerals have the same or similar configuration and operation as the aforementioned embodiments, and the similarities and similarities will not be further described here. Incidentally, some components mentioned in the first embodiment have been omitted from the drawings to facilitate understanding of the main differences between this embodiment and the first embodiment.
[0045] The primary difference between this embodiment and the first embodiment lies in the configuration of the color-adjusting unit 42. Specifically, the drive module 41 can be a stepper motor or a servo motor. The color-adjusting unit 42 includes a linkage shaft 421 and a color-adjusting member 423. One end of the linkage shaft 421 is connected to the rotating shaft of the drive module 41, or the linkage shaft 421 serves as the rotating shaft of the drive module 41, or the linkage shaft 421 and the rotating shaft of the drive module 41 are linked via components such as a transmission belt or gears. The axis of the linkage shaft 421 is parallel to the light-emitting surface 21, and the drive module 41 drives the linkage shaft 421 to rotate. The color-adjusting member 423 is disposed at the other end of the linkage shaft 421 and comprises a plurality of color-adjusting plates 422 arranged in a ring. For example, four color-adjusting plates are arranged at 90-degree intervals; alternatively, three color-adjusting plates are arranged at 90-degree intervals within a sector with a central angle of 180 degrees; alternatively, two color-adjusting plates are arranged at 180-degree intervals, and so on. In this embodiment, three color palettes are arranged at intervals of 90 degrees within a sector-shaped range with a central angle of 180 degrees as an example.
[0046] With this configuration, when the driving module 41 drives the linkage shaft 421 to rotate, for example, by a predetermined angle, the color palette 422 can be switched from not shielding the light-emitting surface 21 to shielding the light-emitting surface 21; conversely, when the driving module 41 drives the linkage shaft 421 to rotate, for example, in the reverse direction by a predetermined angle, the color palette 422 can be switched from shielding the light-emitting surface 21 to not shielding the light-emitting surface 21. Incidentally, due to the provision of multiple color palettes 422, the accuracy of the rotation angle of the driving module 41 can be lower than that of the driving module 41 of the first embodiment, thereby enabling the selection of a more cost-effective driving module 41. Alternatively, each color palette 422 can be configured to convert to a different chromaticity, such as yellow, red, and blue, so that the lamp L with a color-changing function of the present application can emit light of two or more chromaticities.
[0047] See also Figure 7 , which is a schematic diagram of a third embodiment of a color-changing lamp of the present application. In this embodiment, components with the same reference numerals have the same or similar configuration and operation as the previous embodiments, and the similarities and similarities will not be repeated here. Incidentally, some components mentioned in the previous embodiments have been omitted from the drawings to facilitate understanding of the main differences between this embodiment and the previous embodiments.
[0048] The primary difference between this embodiment and the first embodiment lies in the configuration of the color adjustment unit 42. Specifically, the drive module 41 can be a stepper motor or a servo motor. The color adjustment unit 42 includes a linkage shaft 421 and a color adjustment plate 422. One end of the linkage shaft 421 is connected to the rotation axis of the drive module 41. The axis of the linkage shaft 421 is perpendicular to the light-emitting surface 21, and the drive module 41 drives the linkage shaft 421 to rotate. The color adjustment plate 422 is disposed at the other end of the linkage shaft 421.
[0049] With this configuration, when the driving module 41 drives the linkage shaft 421 to rotate, for example, 180 degrees, the color matching plate 422 can be converted from not blocking the light-emitting surface 21 to blocking the light-emitting surface 21; conversely, when the driving module 41 drives the linkage shaft 421 to rotate, for example, 180 degrees in the opposite direction, the color matching plate 422 can be converted from blocking the light-emitting surface 21 to not blocking the light-emitting surface 21; wherein, 180 degrees is only an example, and the angle is set to enable the color matching unit 42 to block or not block the light-emitting surface 21, so no special limitation is made here.
[0050] See also Figure 8 , which is a schematic diagram of a fourth embodiment of a color-changing lamp of the present application. In this embodiment, components with the same reference numerals have the same or similar configuration and operation as the previous embodiments, and the similarities and similarities will not be repeated here. Incidentally, some components mentioned in the previous embodiments have been omitted from the drawings to facilitate understanding of the main differences between this embodiment and the previous embodiments.
[0051] The primary difference between this embodiment and the first embodiment lies in the configuration of the color-adjusting unit 42. Specifically, the drive module 41 can be a telescopic pneumatic or hydraulic cylinder. The color-adjusting unit 42 includes a color-adjusting plate 422. The color-adjusting plate 422 is mounted on the telescopic shaft 411 of the drive module 41. The drive module 41 drives the color-adjusting plate 422 to move linearly.
[0052] With this configuration, when the telescopic shaft 411 of the driving module 41 changes from retracting to extending, the color palette 422 can be converted from not blocking the light-emitting surface 21 to blocking the light-emitting surface 21; conversely, when the telescopic shaft 411 of the driving module 41 changes from extending to retracting, the color palette 422 can be converted from blocking the light-emitting surface 21 to not blocking the light-emitting surface 21.
[0053] The lamp with color-changing function of the present application has the function of providing light of different chromaticities while simplifying the structural parts and not affecting the brightness. It allows users to manually or automatically adjust the switching of white light or yellow light according to, for example, weather conditions, thereby effectively responding to lighting needs in different climates and effectively improving driving safety.
