PickVidsBuilding a realistic artificial sun (for dark winter days)
推荐理由
The result is quite stunning. I've never seen anything like it.
说明
这是2020年由DIY Perks发布的一部演示，主题归在Home, DIY & practical skills。它讲的是artificial sunlight这一支里的具体问题，而不是把整个领域扫一遍。适合已经能看懂基本术语、想继续往下走的人。内容上可以概括成：DIY Perks builds a realistic artificial sun for dark winters, using a powerful water-cooled LED, a satellite dish reflector for near-parallel rays, and a scattering layer to mimic the blue sky. The video explains the optics behind why most lamps do not look like sunlight and shows the build and its results.这些读者给出的理由，核心是：Whenever HN discusses seasonal affective disorder, myopia, or bright home lighting, people point to this as the most convincing buildable example of sunlight-like illumination.讲法不绑某一条新闻，过几年仍然可以当材料看。从2020年到2025年，有9位不同的读者在8个不同月份把它推荐出来，其中明确叫别人去看的有3次。适合先看结果再决定要不要深挖的人。先看它做成了什么。如果已经会了基本定义，就把注意力放在它怎么把artificial sunlight变成能跟着复述的例子。
