对于我们使用它,切割铝和铝型材,刀片很好地举起。目前的刀片于2014年1月购买。它只用来做一年的几百个削减,所以它真的没有很多时间。

您能共享数据表还是LED的来源?看着图片,它们似乎是UVA 400nm紫色LED 5mm Clear Len LED。如果这是真的,那么它们会产生UV-A。当大多数人思考他们正在谈论uv-c的紫外线消毒性质时。一个很棒的起点是:https://iuva.org/iuva-fact-sheet-on-uv-disinfection-for-covid-19或https://www.waveformlighting.com/uv-c-led/what- is- uv-a-uv-c之间的差异是您构建的uv-a-uv-c是一个很好的UV-A(Blacklight)手电筒。它会让事情发光,但我会非常谨慎地制作消毒性质的蛤蜊。
很酷,谢谢你的信息。您可能想看看://www.sledutah.com/a-complete-stem-curriculum-for-37-cents-per-studen/他们使用类似的LED。对该(和所有UV-A)LED的物理,安全性和杀菌性质有很好的讨论。执行摘要是他们不是“病毒杀手”。

你用什么样的玻璃来保护较低的LED?我受到普通玻璃块UV-C的印象。
不,我没有,但谢谢。这是一个有趣的想法,我将尝试。我看到Adafruit有一个产品(https://www.adafruit.com/product/4749)和亚马逊有(https://www.amazon.com/rock-hard-plastics-acrylic -plastiras/dp/b082zbl1xr/)。你会注意其他建议吗?是否有一系列的不适应是最佳的?
Please check my math.DC amps to watts P(W) = I(A)× V(V)Where:P is Power in wattsI is Current in ampsV is DC Voltsin voltsSo 80 amps x 5 volts = 400 wattsLet’s walk through the power supply sizing calculation. Now according to the manufactures data sheets for a 64 x 32 RGB LED matrix panel the maximum current draw for current for all LEDs illuminated is ~4A and for a 64 x 64 panel is ~5 amps. My measured values are less than this but we will use the data sheets for this calculation. The two largest displays we have constructed using this method are a 4 by 4 matrix and (2) 4x2 matrix in a single frame. The 4 by 4 matrix uses 64 x 64 panels and the other used 64 x 64 panels. This gives us:16 x 5 amps = 80 amps and 16 x 4 amps = 64 amps potential maxim draw. Applying the safety factor( 20%) …

This gives us:16 x 5 amps = 80 amps and 16 x 4 amps = 64 amps potential maxim draw. Applying the safety factor( 20%) gives :80 amps * 1.2 = 96.0 amps rounded up gives us 100 amps64 amps * 1.2 = 76.8 amps rounded up gives us 80 ampsAgain this is how we do our sizing calculation. You may have a different methodology based on your needs. I do agree with you that I should have said the biggest display we built for home was 128 x 128, which as true when most of this was written. The takeaway should be watch the wire sizes and layout of your power distribution. This page covers in much more detail. https://github.com/hzeller/rpi-rgb-led-matrix/blob/master/wiring.md
