Abstract:
1. An LED lighting assembly integrated with dielectric liquid lens, comprising: a heat dissipation substrate; an LED chip, located on said heat dissipation substrate; a transparent material, covering said heat dissipation substrate and said LED chip, and having a curved surface; a transparent liquid, located above said transparent material; a transparent layer, located above said transparent liquid; a first dielectric liquid, located above said transparent layer; a second dielectric liquid, located above said first dielectric liquid and having a curved surface, wherein said second dielectric liquid has a second dielectric constant smaller than a first dielectric constant of said first dielectric liquid; a transparent electrode layer, located above said second dielectric liquid for applying a control voltage to generate a dielectric force on said second dielectric liquid; and an enclosing body, having a ring structure combining with said heat dissipation substrate, said transparent layer, and said transparent electrode layer to form two enclosed spaces for accommodating said transparent liquid, said first dielectric liquid, and said second dielectric liquid.
