Title: led fibre optic street light
Post by: innovation_station on March 28, 2007, 04:05:49 PM
yet another thing i invented may years ago

it consists of many led the super bright ones

lots of fibre and some lenses


agin nothing hard here

simple



now think of all the street light in the world that consume 1000w  each

and if we designed a  light that consumed only a few watts and produced the same volume of light

by meand of harnessing all the light emmited from the leds and layed them the fibre out so it made a huge shower head  like l display


agin more to come on this

just some more of my many ideas

man there are WAY more applications for that idea. Just think of lights in work areas that use less energy than the standard light bulb or florescent lamp. The way you see all those new flashlights with the ultra-bright LEDs, you know that idea can be exploited and used for different applications.

do you think you could come up with a circuit design that could be used for your project? I'm very interested in this idea of yours.

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.

There are still other applications that can use this idea. The smaller area of a workbench or even a modest sized room can probably be illuminated by a modest sized cluster of LED powered Fiber Optic lighting clusters

like i said i designed this years ago i just thought i would share it im sure with the right combnations with led fibre and lenses we can achive somthing close but with a lot less power sure it will not have the same effect as street lights but it would use a lot less power and be plenty bright so mabe we need more or they mabe have to be much bigger

just another simple idea from me to you

Lumens per watt are important, if we can keep expanding on your setup of LED, Fiber Optics and Lenses, we can get close to the output of a standard Natrium street light, but with a lower power input requirement. Plus the light output of it would not cast a sickly yellow color on everything around it.

If I understand correctly, the idea is to spread the light from a few super bright LEDs by use of fibre optics. Well. Deviding light into a wider area just make the light in each location weaker. The sum of the radiant energy must be at maximum 100% of the light source. If you are luck, maybe 80 - 90% is possible to spread out to different locations - which means two locations will have 40 - 45% of light each.

That's where the lenses come in. They act to focus the spread light before it leaves the  fixture. There will be weakening of course, but with the light from the LEDs being focused by lenses, hopefully the weakening won't be as obvious.

Not only is lumens per watt input power important, but also the function of the light operation. Some lights are on 24 hours a day - 7 days a week; while others must flash non-stop for years. LEDs are getting more efficient all the time and will no doubt surpass other types of lighting.

It's getting to everywhere you turn now, you see LED lights being used in more and more applications. With the increasing efficiency of  LEDs, its amazing the uses of LED lamps. If we keep working on this idea we can get it to work. Its all up to dreamers like us to change the world.

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.

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.
Title: Re: led fibre optic street light
Post by: innovation_station on April 05, 2007, 05:59:53 PM
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

Post by: Draco Rylos on April 05, 2007, 06:02:51 PM
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.
Title: Re: led fibre optic street light
Post by: innovation_station on April 05, 2007, 06:32:15 PM
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.

@ 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.

I think we all understand the problem - maximize (output light (spectrum dependant on application),operating time(pulsed depending on application)) while reducing (input wattage,material(production,volume)). This leaves much room for experimention.

The best solution is to eliminate the need for lighting. (c: For example, I've known where my body parts are for several years now and don't use a light for showering or using the toilet at night. My eye condition has the side effect of excellent night vision - blind during the day without my glasses, though.

I'd like to see roads disappear all together and the traffic lights with 'em. Too bad the gravity on this planet is so heavy. Hopefully, I'll be able to move to another planet soon...

well we can not elelamate the need for light but we can build somthing that is cheep and works verry well and costs almost nothing to run

that can all be done easly
