Comparison of Luminous Efficiency of InGaN-based High-voltage LED with Traditional High Power LED主要从三个不同角度探究并分析了基于In gA n材料的高压lEd的发光效率优于传统大功率lEd的原因.为了保证实验结论的可靠性,文中所采用的实验样品具有相同的芯片尺寸和材料以及相同的封装结构.经过大量的实验证明,更...
同一产品对不同菌种的杀菌效果对比Comparison of germicidal efficacy of the same product to different strains 某客户委托金鉴实验室对UV LED灯具进行杀菌测试。金鉴工程师测试此款灯具中心波长为275nm,在照射距离1m时其辐射强度为98μW/cm 2,垂直照射15min后对比空白组评价对白色念珠菌、金黄色葡萄球菌及大肠杆菌...
2. High Reliability: They come with multiple anti-vibration structural designs, providing excellent anti-vibration performance for reliable use in high-frequency vibrations. 3. Luminous Efficiency: LED beam lights' reflectors are made from mirror-aluminum material with precise distribution of light and ...
This paper only simulates the luminous efficacy of radiation of source. Figure 1 provides the comparison on the luminous efficiency of several traditional lighting sources and white LED. The luminous efficiency of high pressure sodium lamp , metal halide lamp , and fluorescent lamp is relatively ...
