Disclosed herein are puddle lamps with static and dynamic image projections.
Motor vehicles include various exterior and interior lamps for increasing visibility during non-daylight hours. These lamps may be automatic, and may include head-lamps, interior running lights, etc.
A vehicle ground illumination system may include a housing configured to maintain an image projector and a light projector and a controller in communication with the image projector and the light projector. The controller may be configured to instruct the image projector to project an image in an illumination area, and instruct the light projector to project a white light in the illumination area, wherein the white light is projected to at least partially surround the image projector.
A vehicle mirror having a vehicle ground illumination system may include a housing configured to maintain an image projector and a light projector, the image projector having a first light and being arranged within the housing, and configured to project an image in an illumination area, and the light projector having a second light and being arranged within the housing and configured to project a light in the illumination area, wherein the light is projected to at least partially surround the image projector.
The embodiments of the present disclosure are pointed out with particularity in the appended claims. However, other features of the various embodiments will become more apparent and will be best understood by referring to the following detailed description in conjunction with the accompanying drawings in which:
As required, detailed embodiments of the present invention are disclosed herein; however, it is to be understood that the disclosed embodiments are merely exemplary of the invention that may be embodied in various and alternative forms. The figures are not necessarily to scale; some features may be exaggerated or minimized to show details of particular components. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a representative basis for teaching one skilled in the art to variously employ the present invention.
Disclosed herein is a ground illumination system for a vehicle that includes a light source configured to emit light. The system includes a reconfigurable display element to project an image in combination with a light projector or laser or PICO projector. The light projection and the image projection may be combined in a single unit wherein an icon or animated image may be projected within an area illuminated by the light source. The logo or image may be customizable during manufacturing.
The vehicle 102 may include at least one winglet 104, such as a vehicle mirror (as shown in
While the light mechanism 110 is described throughout as being arranged on the winglet 104, the light mechanism 110 may also be mounted on other exterior areas of the vehicle 102. For example, the light mechanism 110 may be arranged on a door handle. The light mechanism 110 may be arranged on running boards, mud flaps, roof racks, bumpers, etc. The vehicle 102 may include more than one light mechanism 110. In one example, a light mechanism 110 may be arranged on each side view mirror. A light mechanism 110 may also be arranged on each door handle.
The light projector 122 may be configured to emit light into the illumination area 114, referred to herein as the light projection 128. This may be intended to light up an area in front of the vehicle as a user approaches the vehicle. The light may include a white light or color light.
The image projector 120 and the light projector 122 may be coupled to a controller 130. The controller 130 may be coupled to a memory (not shown) and may be configured to control the illumination of the image projector 120 and the light projector 122. The controller 130 may include a printed circuit board (PCB) configured to electronically couple the image projector 120 and the light projector 122. The controller 130 or PCB may include a connector or dual wires.
The image projector 120 may include a first light 131 coupled to the controller 130. The first light 131 may be a light emitting diode (LED) or plurality of LEDs configured to emit light. The image projector 120 may also include various filters 136 configured to aid in generating the logo. The optical filters may selectively transmit lights of different wavelengths. For example, the image projector 120 may include a color filter configured to generate a color logo or image. The filters may be absorptive or dichroic. The filters may be selected during manufacturing depending on the type of image to be projected.
The image projector 120 may include a first optical lens 156a and a film 141 having an outline of an image. The film 141 may allow certain light to pass through the film 141, while blocking other light, in order to generate the image. This film 141 may be interchangeable at the manufacturing stages in order to customize the image for each vehicle. The film 141 and filters 136 may be arranged and maintained in an optical assembly 142. The optical assembly 142 may then be locked into place within the housing 118 by the lens 140. The image projector 120 may also include a second optical lens 156b followed by a filter 136.
The light projector 122 may include the second light 132. The second light 132 may be a light, an LED or plurality of LEDs configured to emit light, similar to the first light 131. In one example, the second light 132 may be a white LED configured to emit substantially white light. The first light 131 may include any one of a color light, wherein a white LED may pass through various filters 136.
The light projector 122 may also include a reflector 157 with a remote phosphor filter 152. This may allow the light projection to alter in color and brightness. The light may pass through the remote phosphor filter 152 to change the color.
Although not specifically shown, the image projector 120 may also include a PICO projector module in lieu of the laser projector 158 of
The system 110 may include the housing 118 capped at the bottom by the outer optical lens. A housing cover may be arranged at the top of the housing. The housing cover may include ribs disposed in a circular axis to radiate heat from the first light and second light. A gasket may be arranged between the housing 118 and the housing cover, and may maintain some of the components within the housing 118 at a fixed location. The first controller 130a and second controller 130b, may be arranged within the housing 118. The second controller 130b may be aluminum to aid in dissipating heat from the white LED of the second light 132. The housing 118 may also house at least one of the optical lenses 156. In some examples, two, three, or more, optical lenses 156 may be included in the system 110. The film 141, hosting the image or logo, may also be included.
In one example, the film 141 and optical lens 156 may include a pair of collimating lenses followed by the film 141, followed by a focusing lens (not shown). The housing 118 may be enclosed by the housing cover and the outer optical lens 140. Further, the housing 118, outer optical lens 140, and housing cover may be hermetically sealed in order to protect the elements therein. The housing cover and lens may be over-molded to the housing 118 in order to hermetically seal the housing 118 and protect the elements therein. This may allow multiple materials to be sealed and assembled and decrease tooling and assembly time.
Computing devices described herein generally include computer-executable instructions, where the instructions may be executable by one or more computing or hardware devices, such as those listed above.
