Development of LED Light Sources in Landscape Lighting

Abstract

An LED light source, which is extensively used in landscape design, has played a good role in its application due to its characteristics and advantages. On the basis of cost­effectiveness analysis, green lighting energysaving technologies that use LED light sources in landscapes are analyzed, as well as the key factors that affect the cost­effectiveness of various stakeholders. Results show that the costeffectiveness analysis method is effective for evaluating the DSM technology. Moreover, the application of LED light source in landscape lighting has great feasibility. This study provides some theoretical reference for the promotion of green lighting energysaving technology.

Two-Step Chemical Mechanical Polishing of Stainless Steel

“…Su et al 15 studied the CMP of stainless steel using alumina abrasives and found the type of oxidants and pH of polishing fluid affected the MRR and polishing mechanism. Wang et al 16 investigated the effect of H 2 O 2 on the chemical-mechanical polishing properties of bearing steel and showed that the mass fraction of H 2 O 2 was relevant to the strength of the reaction layer formed on the surface. Zhang et al 17 optimized the CMP of S-136 steel and obtained high MRR of 187 nm min −1 and ultra-smooth surface with RMS roughness of 3.01 nm.…”
