Polarized LED cap light

The utility model relates to a polarized LED cap light which comprises a support, an LED chip and a package lens. The support is provided with a positive pin, a negative pin and an inner reflector, and the package lens packages the inner reflector and comprises a lens seat and a lens curve. The inner reflector is obliquely arranged on the negative pin and turns to the positive pin; the lens curve is in axial-plane asymmetry of C90-270 DEG C and in symmetry of C0-180 DEG C, and the curvature of the lens curve affects refraction of emergent light rays of the inner reflector. The LED cap light is good in polarization effect and high in utilization rate of light sources, and can be mounted to lighting facilities (such as garden lamps) or display equipment (such as LED display screens) which is mounted at high level.
