  • Illumination device with encapsulated lens
    Patent number: 11415808
    Abstract: An example device may include a light source, an optical element, and an encapsulant layer. A light beam generated by the light source may be received by the optical element, and redirected into the encapsulant layer. The optical element may include a high-index material, for example, with a refractive index of at least approximately 1.5 at the wavelength of the light beam. The light source may be a semiconductor light source, such as a light emitting diode or a laser. The optical element may be embedded in the encapsulant layer, and the optical element may have a curved exit surface. Refraction at the exit surface of the optical element may redirect the light beam towards a target.
