      The Philippines have been using a make shift version to light up their shacks without electricity. They fill a soda bottle with water and bleach and cut a hole in their roof and place it halfway in and out. It works surprising well to light up their windowless shacks during the day. And when combined with a cheap solar charged, battery powered led like what's in a cheap outdoor pathway light stake, they can have some light at night as well.

    @f7y8u9ugf 5 років тому +6

    Was planning something like this and luckily came across your videos, thank you very much!
    I would need to route sunlight from a little more distance. Could one use less fibers (=less total width) to transmit light and then re-distribute it? I mean, to arbitrarily increase light input while using constant fiber to direct it? Thanks!

    • @3DIYCaptain
      @3DIYCaptain  5 років тому +4

      thank you for your comment, good to know my video can help you :) regarding what you are planning to do, you should get the information about the optical losses of the optical fibers you will use. if you use good optical fibers, you will have like 5dB of losses per km (5dB/km), meaning if you put 10W at the input, after 1 km you will have around 3W. Now, if you use bad fiber like the one I use (for fake starlight sky, PMMA base fibers), they have really higher optical losses, I found one with 200dB/km or even 500dB/km, so again, with 10W in the input, you will have nothing after a km, and not a lot after a couple of meters (the value for 200dB/km is 10W divided by 100000000000000000000, and even worse for 500dB/km optical loss). So if you plan to send light over long distance, use good fibers :) There is also losses regarding the optical coupling, meaning how you will put light in the fiber, as I said in the video, be cautious to adapt the couple lens/fiber to optimize the light you'll be able to propagate. One last point, what do you mean by "arbitrarily increase light"? Let me know if you need more info. You can also look on my channel, I'm working on a 3D printed version of this collector, using good fibers ;)

    This is great stuff! I'm hoping that a single large fresnel lens could be used by decreasing the focal length so that it does not melt the ends of even the silica fiber. I then want to focus the light at the other end of the fiber down to a pen point using another lens. Do you see any complications with this?
    I also saw that you mentioned an "x, y, and z positioning system." Are you designing a sun tracker for it?
    Really looking forward to your additional videos.

    • @3DIYCaptain
      @3DIYCaptain  6 років тому +1

      Thank you very much for your comment :) Well, regarding the melting point it’s a tricky question. Actually, assuming using a silica based fiber and knowing that pure silica melting point is at around 1700°C (1500°C for iron as a comparison) if you reach that temperature on the fiber you’ll have a problem. But I think you’ll need a big lens to get there... and also, be careful, with a fiber, there is often a protective layer (in plastic!!!) that need to be remove before placing the lens at the focal point. Regarding the use of a fresnel lens, as long as you match the numerical aperture of the fiber with the lens property you’re good :) then for the refocusing at the end of the fiber, no problem, but again, you need to choose the optics to not loose too much light (for example: fiber end, convex/Plano lens, Plano/convex lens then where you need to focus) . The x,y,z positioning system is on its way, actually I’m just waiting a good weather window to do the tests/video/experiment. The sun tracker will come later, know the idea is to precisely inject light in the fiber by moving the fiber behind the lens. I hope this will help you. Thank again and stay tuned ;)

      Thanks to you for your comment and interest in this project. Regarding your question, it's possible, but not easy: you'll need a really good collector to achieve wielding/soldering or engraving. By good I mean: a lot of single collector, or a big one (but it's not easy to work with, you can look on my channel, I made a video with a 25cm one and managed to light a match), perfect injection of light in fibres, also a collector that follows the sun to a constant light, and to find a way to easily manipulate the "hot beam" at the output... so not impossible, but quite tricky to do

      Hi! Thank you for your comment. It will depends on the kind of fiber you will use. A fiber act like a filter: some will let more UV than IR light propagate for example. So you need to know these kind of spectral properties. Now I’m using a WF fiber, more expensive but it’s spectral response is quite good from visible to near infrared. I hope to make future tests with plants to see what happen :) only experience will give a good answer ;)

    • @3DIYCaptain
      @3DIYCaptain  2 роки тому

      I hope you will try it too :) the efficiency for a fiber to propagate IR is not the same from one fiber or another. And information regarding the transmission efficiency vs wavelength is not often given. Passive cooling look like a good idea, I wonder how effective it can be, knowing that the core a the fiber is quite small (few micrometers), I guess you need quite a lot of fibers (+ lenses but it limit the injection of light to specific angles...), that's a good project :)

  • @ineerajbatra

    Thanks for such an informative video on a topic thats difficult to find research on. Does this light carry heat also along? I mean like LED(or any other light source) bulbs produce heat when ON, will the sunlight transported in such a way also heat the area that it lights? How long (far) can the end of the fiber be from the source(beginning) , lets say 10 metres? Will the distance affect light intensity? How much equivalent watts of light is produced lets say compared to a LED light bulb source, 30/50 watts? Thanks much.

    • @3DIYCaptain
      @3DIYCaptain  6 років тому

      Thank you for your comment and so many good questions!! Yes light carry heat also, when I will have a little more time I will do an experiment showing this... I think 10m is still good, actually it strongly depends on the property of your optical fiber... the one I use is very cheap, but I'm quite optimistic regarding what would left after 10m, the distance linearly decreases the amount of power, so it's not a strong decrease of light. Unfortunately I don't have the equipment to measure the power, I will try to find a DIY way to do it. Again thank for the question and your interest

    • @3DIYCaptain

      It's possible but it depends on the optical fiber you're using. If it's one made to propagate visible light, you can send light on km range! but the "plastic" fiber like PMMA, you can't aim for really long distance... if your need is to efficiently bring light in a room, I'd recommend to use a good fiber :)

      When you'll received your fiber, make some tests to be sure it's an end glow fiber. I have a 100m side glow, and there is no light at the end, quite frustrating.

  • @wesleyp3024
    @wesleyp3024 2 роки тому

    well in order to save space and time why not make a double lens system so you would use a giant first lens (D) to focus down a bunch of light, then use another lens, a smaller one to refocus it again to be small enough to fit perfectly into the optic fiber? then you dont have to use 20-100 small lenses to collect enough sunlight to light up an indoor grow. then you use 5-10 large lenses, 5-10 small lenses and 5-10 fibers. not only is that easier to setup but its material efficient. the only thing is you might also need a double lens system to expand the light back out on the other side (indoors) and such a system would have enough energy moving through a fiber to quite easily burn or melt anything it shines on. (very condensed light)
