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...
3. Comparison LED headlights advantages LEDs are superior in several aspects. They might be more expensive to purchase than normal light bulbs or halogen bulbs, but their use pays for itself in a short time. The automotive industry in particular uses the positive features of the LED and employs...
Here is a small comparison: a 20 Watt halogen spotlight consumes about as much as an LED spotlight, which consumes about 4 Watts. The energy saving is therefore obvious: at the same brightness, an LED lamp consumes up to 90% less than a halogen lamp. If you are still struggling with th...
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 ...
