LED retrofit equipment that match PAR lamp dimensions is made by some manufacturers. As with the case of LED MR lamps, LED PAR lamps generally use an array of individual LED elements that are unsuitable for reflector operation. Nevertheless, some degree of beam control can be obtained with aperture or lens, and LED PAR 38 replacements with a 40 ...
The most common modern applications of the parabolic reflector are in satellite dishes, reflecting telescopes, radio telescopes, parabolic microphones, solar cookers, and many lighting devices such as spotlights, car headlights, PAR lamps and LED housings. [14] Lighting the Olympic Flame with a parabolic reflector. The Olympic Flame is ...
It uses two reflectors. The primary reflector is a parabolic reflector and the secondary reflector is a spherical reflector. The parabolic reflector directs the light into nearly parallel beams, and the spherical reflector is placed in front of the lamp to reflect light from the lamp back to the parabolic reflector, which reduces spill.
As there is no Parabolic Aluminised Reflector in an LED 'PAR', they would be more accurately referred to as 'LED flood lights'. Many LED fixtures are now made using a small number of high-output diodes that allow the beam to be focused on a "hard edge", allowing full use of gobo/beam effects. LED lighting instruments used on Radiohead's 2008 tour
