The closer the Ra value is to 100, the better the color rendering of the light source, and the smaller the difference between the color presented by the illuminated object and its "original color". What are the hazards of poor CRI? If one is exposed to a light source with poor CRI for...
Environmental considerations: LED displays are often viewed as a more environmentally friendly option due to their long lifespan and low energy consumption. خاتمة When summarizing the choice between LCD and LED displays, we can say that each display technology has its unique advantages...

拆解前,首先测量了亮灯状态下LED灯泡的温度(图2,图3)。目的是确认在外观上存在明显差异的底座(散热部)差异是否会体现在温度上。LED的光线很少含有红外线成分,因此灯光照射的灯罩部分并不会太热。但底座是LED芯片的散热部,因此温度较高。此次在认为底座会变得高温的部分(LED的安装位置附近)粘贴了放射率为0...
