A novel secondary optical design for LED lamps with high color rendering indices (CRI) and adjustable correlated color temperature (CCT) is proposed. RGB LED cells are assembled in a three dimensional manner together with a set of beam mixers. Perfect light mixing is resulted by optimizing the structural parameters of the reflectors and beam mixers. A(More)
In this work, the tensile property and creep behavior of electrodeposited nanostructure Al2O3-Ni composite coatings have been investigated. The nanocomposite coatings were produced by composite electrodeposition technique in a nickel sulphamate bath containing suspended nano-sized Al2O3 particles. The structure of the obtained coatings was characterized by(More)
