Why don’t torches with multiple LED’s have reflectors?
A. Focussing reflectors are used with conventional lamps which give off light in 360degrees. LED’s have built-in lenses and so have light emitting properties similar to glass fibre optics. Reflectors offer little advantage and would have the disadvantage of requiring a form of protection such as a polycarbonate lens. This would cancel out any improvement gained with a reflector. NB. These comment only apply to torches with two or more LED’s and using only LED’s. Torches using Recoil LED’s or LEDs in combination with a xenon or halogen, still require reflectors.
