Abstract

A vehicle light module, a headlight assembly, and a method for communicating information at a panel having transparent and opaque states; a projector device projects light functions or visual representations on the panel when in a partially opaque state and through the panel when in a transparent state.

Claims (32)

1 . A vehicle light module comprising:

a panel having a transparent state and an opaque state, where the panel represents a projection film or screen, where the opaque state has partial or full opacity configured to switch between a partial or complete level of opacity relative to full transparency;

a projector operable to project a light function toward the panel;

a controller that is configured to provide an operation state of the panel between the transparent state and an opaque state,

wherein the controller is configured to activate or deactivate the opaque implementations through a power supply by applying a current or voltage to the panel; and

wherein the projector is configured to project at least one light function or visual information on the panel when in the opaque state and is configured to project another light function or visual information through the panel when in the transparent state.

2 . The vehicle light module of claim 1 , wherein the panel includes a type of Suspended Particle Device (SPD) or Polymer Network Liquid Crystal (PNLC), Polymer Dispersed Liquid Crystal (PDLC), a Polymer Dispersed Quantum Dot or a Polymer Dispersed Nanoparticle film or screen device.

3 . The vehicle light module of claim 1 , wherein the controller manages or regulates power supply to the panel film or screen device.

4 . The vehicle light module of claim 1 , wherein the controller activates the power supply to the panel when in the transparent state and deactivates the power supply when in the opaque state.

5 . The vehicle light module of claim 1 , wherein the controller activates the power supply to the panel when in the opaque state and deactivates the power supply when in the transparent state.

6 . The vehicle light module of claim 1 , wherein the panel includes types of electrochromic elements whose transmission properties for light can be altered or modified as a function of applied voltages or electrical current.

7 . The vehicle light module of claim 1 , wherein at least one of the following assemblies is included in the vehicle light module: a headlamp assembly, a tail lamp assembly, an auxiliary or an interior lighted assembly.

8 . The vehicle light module of claim 1 , further comprising: one or more optical elements configured to control an angle or shape of projection of the light function on the second surface.

9 . The vehicle light module of claim 1 , wherein the second surface is a road or air space around a vehicle.

10 . The vehicle light module of claim 1 , wherein the projector is operatively coupled to at least one of the following vehicle structures: a head unit, a windscreen, a window or a transparent surface.

11 . The vehicle light module of claim 1 , wherein the light function is associated with a legal light output or legal function.

12 . A headlight assembly, comprising:

a number of vehicle light modules, where each of the vehicle light modules include a panel having a transparent state and an opaque state, where the panel represents a projection film or screen, where the opaque state is configured to switch between a partial or complete level of opacity relative to full transparency;

a projector media system configured to project a light function or visual information towards a panel, wherein the light function or visual information is configured to display on each panel during said opaque state and is configured to display another light function or visual information through each associated panel when in a transparent state;

a controller adapted to change an operation state of each panel between the transparent and opaque states; and

wherein the projector media system is configured to project at least one light function or visual information on each panel when in the opaque state and is configured to project another light function or visual information through each associated panel when in the transparent state.

13 . The headlight assembly of claim 12 , wherein the controller is configured to activate or deactivate various opaque conditions through a power supply by applying a current or voltage to each panel.

14 . The headlight assembly of claim 12 , wherein the panel includes a type of Suspended Particle Device (SPD), Polymer Network Liquid Crystal (PNLC), Polymer Dispersed Liquid Crystal (PDLC), a Polymer Dispersed Quantum Dot or a Polymer Dispersed Nanoparticle film or screen device.

15 . The headlight assembly of claim 12 , wherein the controller is configured to manage or regulate a power supply to each respective panel and

activates the power supply to the panel when in the transparent state and deactivates the power supply when in the opaque state.

16 . The headlight assembly of claim 12 , wherein the panel includes a type of electrochromic elements whose transmission properties for light can be altered or modified as a function of applied voltages or electrical current.

17 . The headlight assembly of claim 12 , wherein the vehicle light module further includes one or more optical elements configured to control an angle or shape of projection of the light function or visual information through each panel.

18 . A method of communicating information via a vehicle light module, the method comprising:

receiving a number of light output-functions at said vehicle light module; and

projecting the at least one visual representation toward a panel including a projection film or screen having a transparent state and an opaque state, where the opaque state is configured to switch between a partial or complete level of opacity relative to full transparency; and wherein said light output-functions are displayed on the panel when in an opaque state and another light output-function is displayed through the panel when in a transparent state.

19 . The method of claim 18 , further including: using a controller to provide an operation state of the panel between the transparent state and the opaque state.

20 . The method of claim 19 , wherein the controller activates or deactivates opaque implementations through a power supply by applying a current or voltage to the panel.
