Abstract

A vehicular overhead console module includes a base portion configured to attach at an interior cabin portion of a vehicle. A light source is accommodated by the base portion and is electrically operable to emit light. A light transmitting panel is disposed at the base portion and includes an electrically dimmable medium. The electrically dimmable medium is adjustable at least between a first light transmission state, where the light transmitting panel has a first level of light transmissivity, and a second light transmission state, where the light transmitting panel has a second level of light transmissivity. The first level of light transmissivity is greater than the second level of light transmissivity. When the electrically dimmable medium is at the first light transmission state, light emitted by the light source passes through the light transmitting panel to illuminate at least a portion of an interior cabin of the vehicle.

First claim

The invention claimed is:

1. A vehicular overhead console module, the vehicular overhead console module comprising:
a base portion configured to attach at an interior cabin portion of a vehicle to mount the vehicular overhead console module at the interior cabin portion of the vehicle;
a light source accommodated by the base portion;
wherein the light source, with the base portion attached at the interior cabin portion of the vehicle, is electrically operable to emit light;
a light transmitting panel disposed at the base portion, wherein the light transmitting panel includes an electrically dimmable medium;
wherein the electrically dimmable medium is adjustable at least between (i) a first light transmission state, where the light transmitting panel has a first level of light transmissivity, and (ii) a second light transmission state, where the light transmitting panel has a second level of light transmissivity, and wherein the first level of light transmissivity is greater than the second level of light transmissivity; and
wherein, with the base portion attached at the interior cabin portion of the vehicle, and at least when the electrically dimmable medium is at the first light transmission state, light emitted by the light source, when electrically operated to emit light, passes through the light transmitting panel to illuminate at least a portion of an interior cabin of the vehicle.

2. The vehicular overhead console module of claim 1 , wherein a structure of the light source, with the electrically dimmable medium at the second light transmission state and with the light source not electrically operated to emit light, is at least partially concealed by the light transmitting panel.

3. The vehicular overhead console module of claim 1 , wherein a structure of the light source, with the electrically dimmable medium at the first light transmission state and with the light source not electrically operated to emit light, is at least partially viewable through the light transmitting panel.

4. The vehicular overhead console module of claim 1 , wherein the electrically dimmable medium is at the first light transmission state when the light source is electrically operated to emit light, and wherein the electrically dimmable medium is at the second light transmission state when the light source is not electrically operated to emit light.

5. The vehicular overhead console module of claim 4 , wherein, responsive to the light source being electrically operated to emit light, the electrically dimmable medium is adjusted from the second light transmission state to the first light transmission state.

6. The vehicular overhead console module of claim 1 , wherein the electrically dimmable medium is adjustable between the first light transmission state and the second light transmission state based on a determined ambient light level at the interior cabin portion of the vehicle, and wherein, responsive to the determined ambient light level being above a threshold ambient light level, the electrically dimmable medium is adjusted from the first light transmission state to the second light transmission state.

7. The vehicular overhead console module of claim 1 , wherein the electrically dimmable medium is further adjustable to a third light transmission state where the light transmitting panel has a third level of light transmissivity, and wherein the third level of light transmissivity is greater than the second level of light transmissivity and less than the first level of light transmissivity.

8. The vehicular overhead console module of claim 7 , wherein the electrically dimmable medium is adjustable between the first light transmission state and the third light transmission state when the light source is electrically operated to emit light, and wherein the electrically dimmable medium is at the second light transmission state when the light source is not electrically operated to emit light.

9. The vehicular overhead console module of claim 1 , wherein the light source is electrically operable to emit visible light, and wherein the first level of light transmissivity and the second level of light transmissivity are based on respective levels of visible light that passes through the electrically dimmable medium when the electrically dimmable medium is at the first light transmission state and when the electrically dimmable medium is at the second light transmission state.

10. The vehicular overhead console module of claim 1 , wherein the light source is electrically operable to emit near infrared (near IR) light, and wherein the first level of light transmissivity and the second level of light transmissivity are based on respective levels of near IR light that passes through the electrically dimmable medium when the electrically dimmable medium is at the first light transmission state and when the electrically dimmable medium is at the second light transmission state.

11. The vehicular overhead console module of claim 10 , wherein a structure of the light source, when the electrically dimmable medium is at the first light transmission state and when the electrically dimmable medium is at the second light transmission state, is at least partially concealed by the light transmitting panel.

12. The vehicular overhead console module of claim 1 , wherein the electrically dimmable medium comprises a liquid crystal element.

13. The vehicular overhead console module of claim 1 , wherein the light transmitting panel comprises an inner glass panel and an outer glass panel, and wherein the electrically dimmable medium is disposed between the inner glass panel and the outer glass panel.

14. The vehicular overhead console module of claim 13 , wherein the electrically dimmable medium comprises an electrochromic medium.

15. The vehicular overhead console module of claim 1 , wherein the electrically dimmable medium is adjusted to the first light transmission state when electrically powered, and wherein the electrically dimmable medium is adjusted to the second light transmission state when not electrically powered.

16. A vehicular overhead console module, the vehicular overhead console module comprising:
a base portion configured to attach at an interior cabin portion of a vehicle to mount the vehicular overhead console module at the interior cabin portion of the vehicle;
a light source accommodated by the base portion;
wherein the light source, with the base portion attached at the interior cabin portion of the vehicle, is electrically operable to emit visible light;
a light transmitting panel disposed at the base portion, wherein the light transmitting panel includes an electrically dimmable medium;
wherein the electrically dimmable medium is adjustable at least between (i) a first light transmission state, where the light transmitting panel has a first level of light transmissivity, and (ii) a second light transmission state, where the light transmitting panel has a second level of light transmissivity, and wherein the first level of light transmissivity is greater than the second level of light transmissivity;
wherein the first level of light transmissivity and the second level of light transmissivity are based on respective levels of visible light that passes through the electrically dimmable medium when the electrically dimmable medium is at the first light transmission state and when the electrically dimmable medium is at the second light transmission state;
wherein, with the base portion attached at the interior cabin portion of the vehicle, and at least when the electrically dimmable medium is at the first light transmission s
