LCOS微型投影系统的LED照明设计

光学技术 2007年第5期33卷 751-753页

作者：李晓艳钟伯亮王乐金尚忠中国计量学院信息工程学院杭州310018 凤凰光学集团有限公司上海200070

随着LCOS(Liquid Crystal on Silicon)技术的发展,投影仪趋于微型化,传统的UHP(Ultra High Performance)光源已经不适合作为微投系统的光源。使用LED阵列作为微投系统的光源,分别采用CPC(Compound Parabolic Con-centrator)集光器和锥形光棒来耦合光束,使光源发出的光束会聚在LCOS上。分析结果表明,这两种照明系统都具有很好的调节光束角度和收集光束的能力,并在微型投影仪中实现高效的均匀照明。

Trap-assisted charge recombination is one of the primary limitationsof restricting the performance of organic solar cells. However, effectivelyreducing the presence of traps in the photoactive layer remains ***, wide bandgap polymer donor PTzBI-dF is demonstrated as an effectivemodulator for enhancing the crystallinity of the bulk heterojunction active layerscomposed of D18 derivatives blended with Y6, leading to dense and orderedmolecular packings, and thus, improves photoluminescence quenching *** a result, the photovoltaic devices exhibit reduced trap-assisted charge recombinationlosses, achieving an optimized power conversion efficiency of over 19%.Besides the efficiency enhancement, the devices comprised of PTzBI-dF as athird component simultaneously attain decreased current leakage, improved chargecarrier mobilities, and suppressed bimolecular charge recombination, leading toreduced energy losses. The advanced crystalline structures induced by PTzBI-dFand its characteristics, such as well-aligned energy level, and complementaryabsorption spectra, are ascribed to the promising performance *** findings suggest that donor phase engineering is a feasible approach to tuning the molecular packings in the active layer, providingguidelines for designing effective morphology modulators for high-performance organic solar cells.

以浙江省三建建设集团有限公司景芳三堡项目对地下水的利用为例,介绍了要求基坑降水的工程在降水阶段对地下水的有效利用方法。即通过建立大型蓄水池和泵房,在降水过程中将地下水集中收集至蓄水池,再利用水泵将收集的地下水输送到现场各用水点。使施工现场进出车辆冲洗、塔吊喷淋系统、围墙喷淋系统、结构施工过程中模板冲洗、混凝土养护用水、项目绿化浇灌等尽可能采用地下水。如此不仅符合浙江省委十三届四次全会关于"五水共治"要求,做到节约用水,而且有助于项目的成本降低。对类似工程的水资源节约具有一定的借鉴作用。

Photoactive complexes of nonprecious transition metals, mainly including those in the first-row and partially the second-row of the Periodic table of elements, have received increasing attention in view of their low cost and long-term sustainability. They are recognized as promising alternatives to noble transition metal complex congeners that have been extensively studied in optoelectronic devices, artificial photosynthesis, photocatalysis, biodiagnostics, and therapeutics, etc. This review is devoted to a comprehensive summary on the classical and recent advances on photoactive nonprecious transition metal complexes, including photoactive Zr, V, Cr, Mo, and W complexes, Mn complexes and hybrids, Fe, Co, Ni, and Cu complexes, and Zn and Cd complexes and hybrids. A particular focus is given on the molecular design, modulation of photophysical and photochemical properties, and applications of the representative and lately-developed nonprecious metal complexes. In addition, a perspective on the future development in this field is provided at the end of this review.

Random integration of massive distributed photovoltaic (PV) generation poses serious challenges to distribution networks. Voltage violations, line overloads, increased peak–valley differences, and power-flow reversals can occur at different locations, times, and severities. Traditional planning methods such as energy storage (ES) allocation and upgrading of lines may result in poor economics and low equipment utilization. This study proposes a distribution-network planning strategy that coordinates three planning mechanisms:ES allocation to substations and to feeders, and line upgrading. The proposed strategy achieved the lowest annual cost, considering the distribution network problems at different locations, times, and severities. A net load curve description method was first proposed considering economic planning and the uncertain distribution of loads and PVs. Second, a multistage optimization model for ES allocation and line upgrading was established based on the net load curves. Finally, an improved IEEE33 node system was used in the case study. The planning results show that the proposed coordinated planning strategy can address the problems caused by the random integration of massive distributed PVs, improve equipment utilization, and obtain the lowest total annual planning cost.
