Abstract
Abstract A mirror arrangement including a transparent glass member, a translucent film behind the glass member, a light generating element having a configuration for conveying information when activated, the mirror arrangement functioning as an ordinary mirror when no voltage is applied to the light generating element such as an electroluminescent element while functioning as a light source or display panel when the voltage is applied to the light generating element, since the element energized emits light through the translucent aluminum film and the glass in front.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
124 words
A mirror arrangement comprising: a transparent glass member, translucent electrode means fixed to cover one side of said transparent glass member for reflexing part of light coming through said glass member and passing at the same time the remaining light therethrough, a planar light emitting element, fixed to said translucent electrode means, for emitting light upon application thereto of a voltage so as to project light through said translucent electrode means and said transparent glass member, and an electrode fixed to cover said light emitting element said electrode and translucent electrode means for applying said voltage to said light emitting element, whereby the arrangement works as an ordinary mirror when no voltage is applied and as a light source when the voltage is applied.
Claim 2
Dependent Claim
124 words
A mirror arrangement comprising: a transparent glass member, translucent electrode means fixed to cover one side of said transparent glass member for reflexing part of light coming through said glass member and passing at the same time the remaining light therethrough, a planar light emitting element, fixed to said translucent electrode means, for emitting light upon application thereto of a voltage so as to project light through said translucent electrode means and said transparent glass member, and an electrode fixed to cover said light emitting element said electrode and translucent electrode means for applying said voltage to said light emitting element, whereby the arrangement works as an ordinary mirror when no voltage is applied and as a light source when the voltage is applied.
Claim 3
Dependent Claim
128 words
A rear view mirror arrangement for vehicles comprising: a transparent glass member, a translucent thin film of aluminum secured to cover one side of said transparent glass member for reflexing part of light coming through said glass member and at the same time passing the remaining light therethrough, a planar light emitting element secured to said thin film, and an electrode secured to cover said light emitting element for applying voltage to said element so as to energize the element, whereby the light emitting element emits light through said thin film and said transparent glass member upon application of said voltage so that the mirror arrangement works as a light source when the voltage is applied and as an ordinary rear view mirror when no voltage is applied.
Claim 4
Dependent Claim
128 words
A rear view mirror arrangement for vehicles comprising: a transparent glass member, a translucent thin film of aluminum secured to cover one side of said transparent glass member for reflexing part of light coming through said glass member and at the same time passing the remaining light therethrough, a planar light emitting element secured to said thin film, and an electrode secured to cover said light emitting element for applying voltage to said element so as to energize the element, whereby the light emitting element emits light through said thin film and said transparent glass member upon application of said voltage so that the mirror arrangement works as a light source when the voltage is applied and as an ordinary rear view mirror when no voltage is applied.
Claim 5
Dependent Claim
28 words
A mirror as claimed in claim 1 or 2, wherein the light emitting element is shaped in a particular form which has a particular meaning to be displayed.
Claim 6
Dependent Claim
37 words
A mirror as claimed in claim 1 or 2, wherein the electrode is shaped in a particular form which has a particular meaning so that the light emitting element emits light in the shape of the electrode.
Claim 7
Dependent Claim
148 words
A rear view mirror arrangement for vehicles comprising: a transparent glass member, a translucent thin film of aluminum deposited on one side of said transparent glass member to cover the same for reflecting part of light coming through said glass member and passing at the same time the remaining light therethrough, an electroluminescence element printed on said reflecting thin film of aluminum to cover the same for emitting light upon application of voltage thereto so as to project light through said thin film of aluminum and said glass member, and an electrode fixed to cover said electroluminescence element in a meaningful shape thereby to apply the voltage with said thin film of aluminum to said electroluminescence element, whereby said mirror arrangement works as an ordinary mirror when no voltage is applied and as a display panel of particular meaning when the voltage is applied to said electroluminescence element.
Claim 8
Dependent Claim
148 words
A rear view mirror arrangement for vehicles comprising: a transparent glass member, a translucent thin film of aluminum deposited on one side of said transparent glass member to cover the same for reflecting part of light coming through said glass member and passing at the same time the remaining light therethrough, an electroluminescence element printed on said reflecting thin film of aluminum to cover the same for emitting light upon application of voltage thereto so as to project light through said thin film of aluminum and said glass member, and an electrode fixed to cover said electroluminescence element in a meaningful shape thereby to apply the voltage with said thin film of aluminum to said electroluminescence element, whereby said mirror arrangement works as an ordinary mirror when no voltage is applied and as a display panel of particular meaning when the voltage is applied to said electroluminescence element.
Claim 9
Dependent Claim
116 words
A mirror arrangement comprising: a transparent glass member; a thin film of translucent layer deposited on one whole surface of said glass member in complete contact relation therewith for uniformly reflecting and passing part of light applied thereto; and light generating means having a light emitting portion that is shaped in a form of information to be conveyed, disposed only behind the translucent layer for uniformly emitting information carrying light therefrom upon application of a voltage thereto, said mirror arrangement functioning as an ordinary mirror when said light generating means is not activated, the light generating means not being visible, and functioning to display said information when said light emitting means is activated by said voltage.
Claim 10
Dependent Claim
116 words
A mirror arrangement comprising: a transparent glass member; a thin film of translucent layer deposited on one whole surface of said glass member in complete contact relation therewith for uniformly reflecting and passing part of light applied thereto; and light generating means having a light emitting portion that is shaped in a form of information to be conveyed, disposed only behind the translucent layer for uniformly emitting information carrying light therefrom upon application of a voltage thereto, said mirror arrangement functioning as an ordinary mirror when said light generating means is not activated, the light generating means not being visible, and functioning to display said information when said light emitting means is activated by said voltage.
