just finished a verry simple drawing fo 1 way this could be layed out altho there many ways hers the pic so you can have an idea of what i was thinking

ist

I had a slightly different idea, but that is what makes ideas develop, people post their ideas and help develop technology to what will be the final product.

lets see what you have in mind i have many more ideas about this but that 1 was easyer to draw as i wanted some kind of drawing on hear b4 the thred got too big

Here's my idea, its similar to what you had in mind, but mine has the lenses after the fiber optics. that way the light is focused after traveling through the fiber optic cables.

nice but i forgot to mention on my drawing that around my leds are 50 plus strands each square repersents 50 or more fibers and after the lens it dubbles with fiber to evenly spred the light ovet the area

ist

ahhh, now i understand. its hard to get that information from a side drawing of something. I thought of that when i had posted my drawing, and by then it was already too late. Maybe we could put another lens after the second set of fiber optics to focus the light more after it reaches the end of the line.

well i was thinking you could keep adding fibre and lenses until you reach the size that it was intended for

but i was also thinking of inverting the leds

but not right now

oh, ok, now i understand, lets one of us try to build it and see if we can get any worthwhile illumination data from experimentation data.

Here is a video of LED traffic light:

@ bitrake thanks for the vid but lets build them much better then those and to replace home lighting where bright light is required like wash rooms kitchens

 make them cheeply and and sell them cheeply and use fibre to distrubitue the light evenly

it is simple pratical and easy

There might be a compact lens design that allows for diffusion of light while minimizing internal losses. Routing light around with fibre only seems good for natural lighting if energy efficiency is important to the design.

@innovation_station

that's the same thing i was saying earlier in the thread. There are many more uses than the original one you came up with. It may take some searching, but we may come up with a lens that would allow for the diffusion of light while minimizing the losses.

Hi the yellow Natrium gas lights in street latern still have the highest light lumen output
per Watts.
Also LEDs can?t compete yet with them, if I remember correctly.
Maybe off topic:

An important issue is the visibility. Measured lumen I believe is not enough if the wavelength present is not optimal for vision. The xenon light or white super bright LEDs I believe give the best visibility pr. watt, but not most lumen pr. watt. Am I totally lost here or do I have a point?

@Low-Q

That's where the lenses come in, and the number of LEDs per square inch also help with the amount of Lumens/watt available.

Lenses help to increase density in a smaller area, but will not help to provide more effect in total.

Well, I'm not an engineer or anything, hell its been 11 years since I graduated from High School. I'm making a lot of guesses along the line, but I try to try to keep my logic straight.
