Jay Holben The next in line on our examination of lighting fixtures is the PAR, which is an acronym for Parabolic Aluminum Reflector. The classic PAR is a reflector and lamp all in one. It is a sealed ...

Parabolic reflectors are found everywhere. They're on dish antennas for television reception, in radar systems, in long distance microphones, and heaven only knows where else. They have the property ...

Parabolic reflectors for solar applications are nice stuff, and making your own is a great project in itself. One of the easiest ways we have seen is that of [GREENPOWERSCIENCE], who uses nothing more ...

“DPR is Wavien's Dual Parabolic Reflector system, which uses two off-axis paraboloid surfaces facing each other and a net effect of imaging a real life or digital generated object and relocates the ...

For a long time, flashes and strobes have dominated photography lighting, but since the advent of video DSLRs, hot lights have been gaining appeal if only because of their flexibility. Now, Broncolor ...

Borrowing from modern telescope design, researchers have proposed a way to concentrate sunlight to ramp up laser efficiency. Legend tells of Greek engineer and inventor Archimedes using parabolic ...

My neighbhor is a environmentalist type person and is trying to contstruct a solar water heater type thing by building some parabolic reflectors. He's a carpenter so he's got most of the contruction ...

Researchers have designed a new LED-based train headlight that uses a tenth of the energy required for headlights using conventional light sources. If operated 8 hours every day, the electricity ...

For the longest time now, I’ve wanted to build a real, proper radio telescope. To me, this means a large parabolic reflector, a feed horn made of brass sheet, coat hanger wire, and at least for the ...

A light rigid structure (of aluminum or other material) which reflects sound to a focus at which a MICROPHONE is placed. This focussing effect is very strong with WAVELENGTHs less than the aperture of ...
