Abstract
A light-mixing flashlight has a body, three light-emitting diodes, three first reflectors, and three second reflectors. The body has a mounting surface formed in the body, a body opening opposite to the mounting surface, and three light recesses formed in an interior of the body. The light-emitting diodes are mounted in the light recesses, and are respectively a red light, a green light, and a blue light light-emitting diode. The first reflectors are formed as parabolic mirrors and are respectively mounted in the light recesses via a working angle. An opening of each first reflector faces toward the corresponding light-emitting diode. The second reflectors are formed as spherical mirrors, are mounted on the mounting surface, and respectively correspond in position to the first reflectors. Therefore, the light-mixing flashlight has an improved emitting efficiency.
