Designing reflector straight line lamp

AI Thread Summary
Calculating a reflector for a straight light tube requires specific parameters, including the desired beam profile and construction type. A parabolic gutter design is recommended, with resources like NASA's optical reflector design calculator available for assistance. Key considerations include whether the beam should be parallel and acceptable variations in the beam profile. Additional factors such as size, weight, and material cost limits are crucial for the design process. To enhance output, using a corner reflector behind the light source can significantly improve directed light.

:welcome: !

Did you do a little research ? Google 'parabolic optical reflector design calculator'and NASA has a nice webpage.

You of course don't want a dish but a kind of parabolic gutter. Formulas in one dimension stay the same.

And: make a sketch ! Do you want the beam to be parallel ('width of 100mm at a distance of 500-700mm') ? Or isn't that so critical ?

You will need to specify some things about the desired result.
  1. Do you want the output to be converging, diverging, or parallel ?
  2. What is the acceptable variation in beam profile ?
  3. Do you want a faceted mirror or a curved surface (i,e. how to construct) ?
  4. Size and weight limits
  5. Material cost limits
The simplest way to triple the directed forward output is to use a corner reflector (in 2D) behind the source. This fact will drive many of the simpler design decisions.

OP will need to repost this thread with their work shown if they want our tutorial help.
 

Thread 'Finding the number of ways to arrange identical balls in a circle (3 different colors)'

I tried to combine those 2 formulas but it didn't work. I tried using another case where there are 2 red balls and 2 blue balls only so when combining the formula I got ##\frac{(4-1)!}{2!2!}=\frac{3}{2}## which does not make sense. Is there any formula to calculate cyclic permutation of identical objects or I have to do it by listing all the possibilities? Thanks

Thread 'Making the denominator of a certain fraction real'

Essentially I just have this problem that I'm stuck on, on a sheet about complex numbers: Show that, for ##|r|<1,## $$1+r\cos(x)+r^2\cos(2x)+r^3\cos(3x)...=\frac{1-r\cos(x)}{1-2r\cos(x)+r^2}$$ My first thought was to express it as a geometric series, where the real part of the sum of the series would be the series you see above: $$1+re^{ix}+r^2e^{2ix}+r^3e^{3ix}...$$ The sum of this series is just: $$\frac{(re^{ix})^n-1}{re^{ix} - 1}$$ I'm having some trouble trying to figure out what to...
