A high operating temperature capable LED luminaire is designed for use in industrial applications that involve high-temperature materials processing or thermal energy generation. In many industries the production process necessitates process heating (treatment at elevated temperatures) to affect solids and liquids heat-up, melting and evaporation or to facilitate reaction mechanisms. Such processes include agglomeration and sintering, calcining, curing, drying, fluid heating, forming, heating and melting, heat treating, metal reheating, smelting, incineration/thermal oxidation, etc. Process heating is used in a vast range of industrial applications, which encompass the manufacturing of advanced ceramics and specialty metals, the production of construction materials (such as cement and wallboard), the recovery of lime in the kraft process of the pulp and paper industry, the application of coatings to metallic and nonmetallic materials (including ceramics and glass), the production of anodes from petroleum coke for aluminum smelting, the extrusion of rubber and plastics, the conversion of iron into steel, the production of metal castings, the hot-shaping of glass and plastic thermoforming, the tempering and annealing of glass and ceramics products, the catalytic steam reforming of hydrocarbons to produce hydrogen and other gases (for the synthesis of ammonia, methanol, etc.), the thermal cracking of hydrocarbons for the production of ethylene, the drying of textiles and polymers, baking, roasting and frying of food, etc.
