a lighting device includes a housing , multiple light emitting diodes , and multiple magnifier lenses . the multiple leds and the multiple magnifier lenses are located in the housing . each of the magnifier lenses corresponds to a different one of the leds , and there are less magnifier lenses than leds . each led that has a corresponding magnifier lens is arranged with respect to its magnifier lens so that substantially all of the light emitted by the led only traverses its corresponding magnifier lens . at least one of the leds emits light that does not traverse any of the multiple magnifier lenses .
