Abstract:
1. A solid-state lighting apparatus comprising: a fixture having a mounting surface, the fixture made of a thermally conductive sheet metal, the fixture is a primary heat sink and dissipates heat in an x axis and a y axis, relative to each other, of the fixture, wherein the fixture has a thickness between 0.5 and 6.0 millimeters, wherein the primary heat sink further comprises a first primary heat sink and a second primary heat sink, the first primary heat sink being a separate unitary structure from the second primary heat sink, wherein at least one of a thermal isolator and a buffer space is positioned between the first primary heat sink and the second primary heat sink; an anodized coating covering the fixture, the anodized coating configured to prevent corrosion and increase thermal conductivity; a metal core printed circuit board (MCPCB) mounted on the mounting surface; a power supply unit enclosed within a housing in the fixture, the power supply unit configured to generate an output voltage, wherein the power supply unit is configured to achieve a power factor greater than 0.98; a solid-state light-emitting source mounted on the MCPCB, the solid-state light-emitting source coupled to the power supply unit, wherein the solid-state light emitting source is one of a Light Emitting Diode (LED), an Organic Light Emitting Diode (OLED), and a Polymer Light Emitting Diode (PLED); a base plane extending from one end of the fixture, wherein the base plane is adjustably inclined with respect to a ground in order to control a photometry of the solid state light emitting source; a secondary heat dissipating panel mounted at a rear of the fixture, wherein the secondary heat dissipating panel is a secondary heat sink, and wherein the secondary heat dissipating panel is made from a thermally conductive material selected from a set of aluminum, iron, steel, and copper; a sensor coupled to the power supply unit for selectively controlling power delivery to the solid-state light-emitting source, wherein the sensor is one of a photo sensor or a motion sensor; a lens mounted on the solid-state light-emitting source to focus a light output from the solid-state light-emitting source, wherein the lens prevents light scatter; and a metallic thermal interface positioned in a cut-out opening of the first primary heat sink, wherein the heat is dissipated from the MCPCB through the metallic thermal interface and to the second primary heat sink.
