Abstract

A signaling assembly is described which includes a semitransparent mirror, an opaque layer attached to the semitransparent mirror, a reflector member positioned within an aperture defined by the opaque layer; a circuit board defining an aperture through which visible light can pass, and which is positioned in spaced relation relative to the semitransparent mirror; and an electromagnetic radiation emitter mounted on the rear surface of the circuit board and which emits visible light which is passed by the circuit board and an opaque layer and which is reflected from the reflector member so as to form a visibly discernable signal which is passed by the semitransparent mirror.

Claims

1. A signaling assembly comprising:

a semitransparent mirror having forward and rearward facing surfaces;

an opaque layer attached to the rearward facing surface of the semitransparent mirror, and which defines an aperture through which visible light may pass;

a reflector member positioned, at least in part, within the aperture which is defined by the opaque layer, and which further has a surface which reflects visibly discernable light;

a circuit board having forward, and rearward facing surfaces, and defining an aperture through which visible light may pass; and

an electromagnetic radiation emitter mounted on the rearward facing surface of the circuit board, and which is positioned in substantially coaxial alignment relative to the aperture defined by the circuit board, and which, when energized, emits visibly discernable electromagnetic radiation which passes through the apertures defined by the opaque layer, and the circuit board, and which further is reflected, at least in part, by the reflector member so as to pass through the semitransparent mirror to form a resulting visible signal.

2. A signaling assembly as claimed in claim 1, and wherein the reflector member is received, at least in part, within the aperture defined by the circuit board.

3. A signaling assembly as claimed in claim 1, and wherein the circuit board is positioned in spaced relation relative to the rearward facing surface of the semitransparent mirror, and wherein the circuit board is juxtaposed, at least in part, relative to the opaque layer and the reflector member.

4. A signaling assembly as claimed in claim 1, and further comprising:

a cover member which is hingedly mounted to the reflector member and which is affixed to the opaque layer, the cover member defining a cavity, and wherein the electromagnetic radiation emitter is received, at least in part, within the cavity.

5. A signaling assembly as claimed in claim 1, and wherein the opaque layer comprises, at least in part, and adhesive layer which positions the reflector member, and the circuit board in an appropriate orientation relative to the semitransparent mirror.

6. A signaling assembly as claimed in claim 1, and wherein the electromagnetic radiation emitter is a reverse gull-wing mounted light emitting diode.

7. A signaling assembly as claimed in claim 1, and wherein the semitransparent mirror is selected from the group which comprises dichroic mirrors, electrochromic mirrors, and substantially neutrally chromatic mirrors.

8. A signaling assembly as claimed in claim 1, and wherein the circuit board is affixed, at least in part, to the reflector member.

9. A signaling assembly comprising:

a semitransparent mirror having forward and rearward facing surfaces;

an opaque layer mounted on the rearward facing surface of the semitransparent mirror and which facilitates the passage of visibly discernable electromagnetic radiation therethrough;

a cover defining an internal cavity and which rests in covering relation relative to the aperture defined by the opaque layer;

a circuit board received within the cavity of the cover and which is further juxtaposed, at least in part, relative to the opaque layer, and wherein the circuit board has a rearwardly facing surface and defines an aperture through which visibly discernable electromagnetic radiation may pass;
