LED luminaire with light control means

An LED luminaire comprising a plurality of LED chips, a substrate on which the plurality of LED chips are mounted, and a light control means provided to the substrate for controlling the distribution of light emitted by the respective LED chips, the light control means including at least one of a plurality of dents and a plurality of protrusions formed at positions where the LED chips are mounted and comprising the substrate per se formed with a light transmitting material, wherein the LED chips are respectively provided with a power-supplying electrode section made of a transparent conductor.

An LED luminaire comprising:

• a resin molded substrate provided at least on one surface thereof with light distribution control means for controlling the distribution of light in a desired direction and with a wiring circuit in a desired pattern, and
• a plurality of LED chips mounted at least on the one surface of the substrate respectively and connected to the wiring circuit and in correspondence to the light distribution control means and wiring circuit,
• wherein the light distribution control means comprises at least one uneven surface of the substrate and wherein the LED chips are mounted on the uneven surface with each LED chip having a p-n junction plane disposed substantially in conformity to the desired direction of the light distribution, the light distribution control means comprising a first light distribution plate including the uneven surface of the substrate and a second light distribution plate including a prism lens plate disposed rotatable on a plane parallel to the substrate in front of the first light distribution plate.

An LED luminaire comprising:

• a resin molded substrate provided at least on one surface thereof with light distribution control means for controlling the distribution of light in a desired direction and with a wiring circuit in a desired pattern, and
• a plurality of LED chips mounted at least on said one surface of the substrate respectively as connected to the wiring circuit and in correspondence to the light distribution control means and wiring circuit,
• wherein the light distribution control means comprises an uneven surface of a transparent resin layer, the uneven surface being disposed outer than the LED chips with respect to the substrate, the light distribution control means comprising a first light distribution plate that comprises a transparent resin layer having the uneven surface and a second light distribution plate of a prism lens plate disposed in parallel to the substrate in front of the first light distribution plate at least the second light distribution plate being rotatable on a plane parallel to the substrate.
