Abstract
The embodiments of the present invention provide a kind of optical lens and a kind of miner's helmet lamp. A kind of optical lens, comprising a reflective surface and a light exit surface; wherein, in a circle with the central position of the said reflective surface as its center, at least a light distribution camber and a reflective camber are set up along the radius direction of the said reflective surface; in a circle with the central position of the said light exit surface as its center, at least a Fresnel annular surface and a surface are set up along the radius direction of the said light exit surface; the said light distribution camber is used for refracting the light incident on the said reflective surface to the said Fresnel annular surface and the said surface; the said reflective camber is used for reflecting the light incident on the said reflective camber to the said surface in collimation; the said Fresnel annular surface is used for reflecting the light incident on the said Fresnel annular surface through the said light distribution camber from the said light exit surface in collimation; the said surface is used for wholly reflecting the incident light through the said light distribution camber to the said reflective camber and for reflecting incident light through the said reflective camber from the said light exit surface in collimation.
