Abstract
A light source has a transparent substrate, a fixed substrate disposed in facing relation to the transparent substrate, and a plurality of electron emitters disposed on a principal surface of the fixed substrate. A light reflecting film is disposed on a portion of the principal surface of the fixed substrate which is free of the electron emitters. An anode electrode in the form of a transparent electrode is disposed on a substantially entire reverse side of the transparent substrate. Phosphor layers are disposed on the anode electrode at respective positions facing the electron emitters.
Claims27
A light source comprising:
- at least one electron emitter;
- a transparent substrate for guiding therethrough a phosphorescent light emission based on electrons emitted from said electron emitter;
- and
- light reflecting means disposed in facing relation to said transparent substrate, for reflecting said phosphorescent light emission to said transparent substrate.
A light source comprising:
- a transparent substrate;
- a fixed substrate disposed in facing relation to said transparent substrate;
- at least one electron emitter disposed on said fixed substrate;
- an anode electrode comprising a transparent electrode;
- a first phosphor layer, said anode electrode and said first phosphor layer being disposed on a surface of said transparent substrate which faces said fixed substrate;
- and
- an auxiliary electrode and a second phosphor layer which are disposed on a portion of said fixed substrate, the portion being free of said electron emitter.
A light source comprising:
- at least one electron emitter;
- a transparent substrate for guiding therethrough a phosphorescent light emission based on electrons emitted from said electron emitter;
- and
- a laminated assembly disposed in facing relation to said transparent substrate, said laminated assembly comprising an anode electrode and a phosphor layer;
- said laminated assembly being oriented such that said phosphor layer confronts said transparent substrate.
