Designing reflector straight line lamp

[Harry Logtenberg]

Homework Statement

Who can help me to calculated a reflector for a straight light tube with a diameter of 6mm and a length of 300mm given a beam with a width of 100mm at a distance of 500-700mm?

Relevant Equations

I do not know.

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.
