Description

Technical Field

[0001] The present invention relates to the field of vehicle-mounted equipment, and in particular to a vehicle projection lamp and a vehicle with the vehicle projection lamp. Background Art

[0002] In recent years, light projection has become a widespread feature of our lives. For example, at outdoor events, people can enjoy light shows projected onto building facades, and even in stage plays and musicals, they can fully enjoy the visual feast brought by light projection. Lighting is more than just illumination. In addition to providing illumination, vehicle lights can also convey driving signals to the driver through projection. For example, projection lights installed under the car doors can illuminate a certain area for the driver when passengers or the driver exit the vehicle, and can also project beautiful patterns.

[0003] Existing projection lights have a short projection distance and are often installed on the underside of vehicle door frames and trunks to provide drivers with warnings or illuminate certain areas when parking. In addition to lighting, existing automotive projection lights also incorporate pattern information into the projection. For example, static projection lights can be used to project hazard warning signals to remind drivers to drive safely. Automotive projection lights also feature dynamic effects, such as turn indicators and dynamic display lights similar to signal lights. These animated projections can better attract road users' attention. This type of projection lighting combines a set of predefined symbols and graphics with animation.

[0004] Since the vehicle's projection light is a certain distance from the ground, the projected pattern displayed on the ground is related to the angle between the projection light and the ground. The driver's perspective inside the car will cause the shape of the pattern seen by the driver to change, thus affecting the driver's correct judgment of the projected pattern.

[0059] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0060] Referring to the accompanying drawings of the present invention Figures 1 to 7The following description illustrates a vehicle projector lamp 100 and a vehicle equipped with the vehicle projector lamp 100 according to a first preferred embodiment of the present invention. The vehicle includes a vehicle body 200, wherein at least one vehicle projector lamp 100 is mounted on the vehicle body 200. The vehicle projector lamp 100 projects projection information onto the ground based on the location of the vehicle body 200, allowing the driver of the vehicle to observe the image information projected on the ground by the vehicle projector lamp 100 based on their own position. It is worth noting that in this preferred embodiment of the present invention, the projection information projected by the vehicle projector lamp 100 at a specific projection angle toward the ground forms a regular pattern, allowing the driver in the vehicle to observe the projected pattern information on the ground.

[0061] By way of example, in this preferred embodiment of the present invention, the vehicle projector lamp 100 is disposed at the front end of the vehicle, wherein the vehicle projector lamp 100 is disposed at a specific tilt angle relative to the vehicle body 200. The vehicle projector lamp 100 projects a stripe pattern at a specific tilt angle toward the ground. The projected stripe pattern is projected in front of the vehicle or in the rearview mirror of the vehicle, providing the vehicle driver and other nearby vehicle drivers with reference information for driving. The vehicle driver observes the regular projection pattern of the vehicle projector lamp projected in front of the vehicle based on their own viewing angle.

[0062] Those skilled in the art will appreciate that the location of the vehicle projector lamp 100 mounted on the vehicle body 200 is merely exemplary. In alternative embodiments of the present invention, the vehicle projector lamp 100 may also be mounted on the side or rear end of the vehicle body 200. It is worth noting that the vehicle projector lamp 100 projects the projection pattern at an angle from the vehicle body 200. The pattern projected on the ground by the vehicle projector lamp 100 appears to the vehicle driver as a regular pattern, such as a regular stripe pattern, a text or numerical pattern, or other graphic file pattern.

[0063] Therefore, the projection pattern is projected onto the ground at a specific tilt angle by the vehicle projection lamp 100 , so that the driver in the vehicle sees regular pattern information based on his or her position.

[0064] The vehicle projector lamp 100 includes at least one light source 10, an imaging device 20, and a lens assembly 30. The lens assembly 30 has an optical axis O, and the light source 10 and the imaging device 20 are arranged along the optical axis O of the lens assembly 30. The light source 10 is located at the front end of the lens assembly 30. The light generated by the light source 10 forms an outwardly projected illumination light path 101 through the lens assembly 30. The imaging device 20 is disposed within the lens assembly 20. The lens assembly 30 guides the light from the illumination light path 101 to the imaging device 20. The light from the illumination light path 101 forms projection light with projection pattern information through the imaging device 20. The projection light from the imaging device 20 forms an imaging light path 102 through the lens assembly 30. The projection light is projected outwardly onto the ground through the imaging light path 102 to form the projection pattern.

[0065] It is worth noting that in this preferred embodiment of the present invention, the vehicle projection lamp 100 projects the projection pattern onto the ground at a predetermined downward projection angle based on its own location. The projection light corresponding to the projection pattern is projected onto the ground surrounding the vehicle via the imaging optical path 102 formed by the lens assembly 30. For example, the vehicle projection lamp 100 is positioned at the front end of the vehicle body 200. The projection pattern projected by the vehicle projection lamp 100 can be a vehicle prompt or a predicted wheel trajectory during driving, allowing the driver to assess road conditions and adjust their driving accordingly.

[0066] like Figure 7 As shown, the optical axis O of the lens assembly 30 of the vehicle projector lamp 100 forms a predetermined angle θ with the horizontal direction, wherein the imaging light path 102 formed by the vehicle projector lamp 100 is tilted downward, and the vehicle projector lamp 100 projects the image light onto the ground based on the imaging light path 102. It is worth noting that the vehicle projector lamp 100 projects the image light onto the ground based on the predetermined installation angle θ, and the projection light projected by the vehicle projector lamp 100 forms an imaging area 103 through the imaging light path 102, wherein the projected image is projected and formed in the imaging area 103.

[0067] It's worth noting that the imaging area 103 formed by the projection light from the vehicle projector lamp 100 is a long, rectangular area, and the projection image of the imaging area 103 observed by the driver from their own position is a regular projection image. Therefore, in this preferred embodiment of the present invention, the vehicle projector lamp 100 projects the projection image light onto the ground at a preset installation angle θ, projecting a pre-corrected projection image onto the ground. This ensures that the projection image observed by the driver in the vehicle is a regular image adapted to the driver's perspective.

The opposing surfaces of the first illumination lens unit 311 and the second illumination lens unit 312 are convex surfaces, and the opposite side surfaces of the first illumination lens unit 311 and the second illumination lens unit 312 are planar structures.
