摘要:

随着人们对照明品质要求的提高,光谱发光二极管(LED)照明成为发展热点。本文对光谱 LED 用关键材料——荧光粉进行了详细分析,对比了每种体系的发光性能并给出了各类型的代表材料,重点阐述了紫光–近紫外光激发的多种颜色荧光粉的优劣势、研究进展以及实际应用情况目前可供光谱使用的紫光–近紫外光激发的荧光粉存在蓝粉和青粉普遍发射光谱窄、光效偏低和热稳定性较差,黄粉及远红光荧光粉对紫光或近紫外光的吸收较低导致发光效率不佳,单一基质白光荧光粉的红光发射不足等问题可重点突破适合紫光–近紫光激发高光效和高热稳定性的宽谱蓝粉、青粉、黄绿粉、黄粉、长波红粉以及单一基质白光荧光粉的制备和应用技术,开发与现有应用产品体系相匹配的高效及连续化制备技术,由此促进光谱LED 的进一步发展。

Dymola-based multi-parameters integrated optimization for high speed transfer system of LED chip sorter

Jie OUYANG, Bin LI, Shihua GONG

《机械工程前沿(英文)》 2013年 第8卷 第2期   页码 118-126 doi: 10.1007/s11465-013-0253-y

摘要:

To enhance the performance of high speed transfer system of LED chip sorting equipment, its control parameters need to be well matching with the mechanical system. In practical issues, it is difficult and time-consuming work to get these parameters matched because their selection is strongly depended on individuals. In current work, an integrated optimization method was carried out to solve this problem, in which the multiple control parameters optimization, modeling and simulation were included, i.e., a multi-domain model of transfer system performed on Dymola platform. Based on this model, the searching area of the key control parameters was narrowed by performing integrated optimization. After that a group of parameters were selected from this narrowed area to perform the equipment’s controls. The result showed this method possesses a simple and reliable nature. The optimal solutions also indicated that the optimized control parameters can well satisfy the requirements of transfer system. On the other hand, it greatly reduced the engineering adjustment time by using this method.

Flexible resonant tank for a combined converter to achieve an HPS and LED compatible driver

Jin HU,Hui-pin LIN,Zheng-yu LU,Feng-wu ZHOU

《信息与电子工程前沿(英文)》 2015年 第16卷 第8期   页码 679-693 doi: 10.1631/FITEE.1500054

摘要: High pressure sodium (HPS) lamp has been widely used in street lighting applications because of its maturity, reliability, high lighting efficiency, long life-time, and low cost. Light emitting diode (LED) is expected as the next generation lighting source due to its continuously improving luminous efficacy, better color characteristic, and super long life-time. The two lighting sources may coexist in street lighting applications for a long time. A novel HPS and LED compatible driver is proposed which is rather suitable and flexible for driving HPS and LED in street lighting applications. The proposed driver combines the LLC and LCC resonant circuits into a flexible resonant tank. The flexible resonant tank may change to LLC or isolated LCC circuit according to the lighting source. It inherits the traditional HPS and LED drivers’ zero voltage switching (ZVS) characteristics and dimmable function. The design of the proposed flexible resonant tank considers the requirements of both HPS and LED. The experiments of driving HPS and LED on a prototype driver show that the driver can drive the two lighting sources flexibly with high efficiency.

摘要: 与传统视频采集技术相比,高分辨率光谱视频采集技术能够为精细农业、环境监测、遥感、军事刑侦等诸多重要领域提供高维度、高精度场景特征信息。传统光谱仪主要采用的扫描系统无法满足动态场景下的采集需求,从而限制了光谱成像技术的应用范围。近来,得益于计算摄像理论和半导体技术的快速发展,光谱视频采集技术成为可能。本文首先详细介绍了传统光谱仪的基本理论与工作原理。其次,针对光谱视频采集的核心问题,从成像理论、系统结构、关键器件等方面回顾了近年出现的瞬拍式光谱采集技术。从进一步提升光谱视频采集精度的角度出发,通过主观质量评价与客观指标比较,分析和总结了各光谱成像系统的性能优势与弊端,同时讨论了计算摄像理论、半导体制备工艺对光谱视频采集技术发展的关键作用。

Effects of red and blue LEDs on

《农业科学与工程前沿(英文)》 2018年 第5卷 第2期   页码 197-205 doi: 10.15302/J-FASE-2018224

摘要: The objectives of this study were to investigate the effects of red and blue LEDs on growth and microtuberization of potato ( ) single-node cuttings. Explants were incubated under 6 light treatments: 100% red LEDs (R), 75% red LEDs+ 25% blue LEDs (3RB), 50% red LEDs+ 50% blue LEDs (RB), 25% red LEDs+ 75% blue LEDs (R3B), 100% blue LEDs (B) and white LEDs (W). Most of the growth and physiological parameters were significantly higher in 3RB than W. Enhancement of leaf area and chlorophyll concentrations were obtained in B. Leaf stomata were elliptical with the lowest density in 3RB. However, those in W were round in shape, and those with the smallest size and the highest density were observed in R. Most of the characteristics of microtuberization were also improved in 3RB. The combined spectra of red and blue LEDs increased the number of large microtubers. The fresh weight of individual microtubers in R and W were increased, but not their number. These results suggest that, of the treatments assessed, 3RB is optimal for the growth of potato plantlets and the combination of red and blue LEDs is beneficial for microtuberization.

《工程管理前沿(英文)》 2021年 第8卷 第2期   页码 284-309 doi: 10.1007/s42524-019-0085-5

摘要: How latecomers from emerging countries catch up on technological innovation is an important topic for industrial practitioners, policymakers, and academic researchers. This study systematically reviews 37 empirical studies on the precursors of industry catch-up in emerging countries. A general framework on what makes a successful catch-up in latecomer industries is suggested based on literature review. The framework comprises six generic determinants, including technological capability, business ecosystem, government roles, market condition, technological regime, and windows of opportunity. In addition, this framework is applied to the Chinese LED industry, and a case analysis of the catch-up is performed in Chinese LED firms.
