Blindzone signal indicator

Claim 2

A display apparatus for blindzone signal indication, comprising; an exterior rear view mirror housing; an exterior rear view mirror disposed in the exterior rear view mirror housing defining a first portion from which light is reflected and a second portion through which light may be transmitted from inside the rear view mirror housing; a light source mounted within the housing located at the second portion of the mirror; and a directional filter located at the second portion of the mirror so that when the light source emits light, a signal from the light source may be seen from the interior of the vehicle, but may not be seen by drivers of other vehicles, wherein the second portion of the mirror includes a hole defined by the mirror and wherein the directional filter is a flat panel directional filter laminated to the mirror over the hole.

Claim 3

The apparatus set forth in claim 1 wherein the flat panel directional filter transmits light at an angle of 60° +/-8° relative to the filter and blocks light at all other angles to the filter.

Claim 4

The apparatus set forth in claim 1 wherein the directional filter is mounted to the exterior of the vehicle mirror.

Claim 5

The apparatus set forth in claim 1 wherein the directional filter is mounted to the interior of the mirror.

Claim 6

The apparatus set forth in claim 1 wherein the light source includes four LED's.

Claim 7

The apparatus set forth in claim 1 wherein the light source, includes a diffuser.

Claim 8

A display apparatus for blindzone signal indication, comprising; an exterior rear view mirror housing; an exterior rear view mirror disposed in the exterior rear view mirror housing defining a first portion from which light is reflected and a second portion through which light may be transmitted from inside the rear view mirror housing; a light source mounted within the housing located at the second portion of the mirror; and a directional filter located at the second portion of the mirror so that when the light source emits light, a signal from the light source may be seen from the interior of the vehicle, but may not be seen by drivers of other vehicles wherein at the second portion of the mirror, the interior surface of the mirror defines a notch within which the directional filter is mounted.

Claim 9

A display apparatus for blindzone signal indication, comprising; an exterior rear view mirror housing; an exterior rear view mirror disposed in the exterior rear view mirror housing defining a first portion from which light is reflected and a second portion through which light may be transmitted from inside the rear view mirror housing; a light source mounted within the housing located at the second portion of the mirror; and a directional filter located at the second portion of the mirror so that when the light source emits light, a signal from the light source may be seen from the interior of the vehicle, but may not be seen by drivers of other vehicles wherein at the second portion of the mirror, the interior surface of the mirror defines a notch within which the directional filter is mounted.

Claim 10

In a motor vehicle, an apparatus comprising; an exterior mirror housing; a circuit board mounted within the housing; a light source mounted to the circuit board and capable of emitting light; an exterior rear view mirror mounted to the housing, defining a first portion through which light is reflected and a second portion through which light from the light source is transmitted; and a micro-louver filter mounted to the rear view mirror proximate to the second portion.

Claim 11

In a motor vehicle, an apparatus comprising; an exterior mirror housing; a circuit board mounted within the housing; a light source mounted to the circuit board and capable of emitting light; an exterior rear view mirror mounted to the housing, defining a first portion through which light is reflected and a second portion through which light from the light source is transmitted; and a micro-louver filter mounted to the rear view mirror proximate to the second portion.

Claim 12

The apparatus set forth in claim 8, wherein the micro-louver filter transmits light emitted from the light source toward an operator of the vehicle, but is opaque to light emitted from the light source in other directions.

Claim 13

A motor vehicle comprising; a driver side exterior rear view mirror housing; a passenger side exterior rear view mirror housing; a first light source mounted in the driver side rear view mirror housing; a second light source mounted in the passenger side rear view mirror housing; a first exterior rear view mirror mounted to the driver side rear view mirror housing, defining a first portion through which light is reflected and a second portion through which light from the first light source is transmitted; a second exterior rear view mirror mounted to the passenger side rear view mirror housing, defining a third portion through which light is reflected and a fourth portion through which light from the second light source is transmitted; a first micro louver filter mounted to the first exterior rear view mirror proximate to the second portion; and a second micro louver filter mounted to the second exterior rear view mirror proximate to the fourth portion, such that the first and second micro louver filters have transmission angles allowing an operator of the vehicle to see light emitted by the first and second light sources, but preventing persons not within the vehicle from seeing said emitted light.

Claim 14

A motor vehicle comprising; a driver side exterior rear view mirror housing; a passenger side exterior rear view mirror housing; a first light source mounted in the driver side rear view mirror housing; a second light source mounted in the passenger side rear view mirror housing; a first exterior rear view mirror mounted to the driver side rear view mirror housing, defining a first portion through which light is reflected and a second portion through which light from the first light source is transmitted; a second exterior rear view mirror mounted to the passenger side rear view mirror housing, defining a third portion through which light is reflected and a fourth portion through which light from the second light source is transmitted; a first micro louver filter mounted to the first exterior rear view mirror proximate to the second portion; and a second micro louver filter mounted to the second exterior rear view mirror proximate to the fourth portion, such that the first and second micro louver filters have transmission angles allowing an operator of the vehicle to see light emitted by the first and second light sources, but preventing persons not within the vehicle from seeing said emitted light.
