Patent ID: 7490969

Claim:
A modulated lighting device being applied to provide a modulated illumination toward at least one selected region, and comprising: a light box shell, comprising: at least one arrangement surface located inside the light box shell; at least one illumination surface located outside the light box shell; and at least one illumination opening formed on the illumination surface; a heat-dissipating plate arranged on the arrangement surface of the light box shell for dissipating a lighting heat generated by providing the modulated illumination; a plurality of lighting emitting diodes (LED) arranged on the arrangement surface for providing a plurality of injection light beams; and plurality of modulation assemblies arranged in a preset array, pivotally connected to the light box shell neighboring to the illumination opening, and each modulation assembly comprising: at least one reflection element having at least one reflection surface neighboring to the arrangement surface for reflecting the injection light beams to generate at least one illumination light beam; and at least one connection mechanism for perforating the reflection element to pivotally connect to the light box shell neighboring to the illumination opening; wherein each of the illumination light beams reflected from one of the modulation assemblies passes through the illumination opening and modulates with the neighbor illumination light beams so as to provide the modulated illumination.
