    摘要: A lighting device that can switch between intensity distributions of emitted light with a simple configuration. The lighting device includes a light source, a polarization controller, and a polarizing plate, in which the polarization controller switches light emitted from the light source between light components having two or more different polarization states to be incident into the polarizing plate, and the polarizing plate functions as a diffraction grating that has two or more regions having different polarization states of transmitted light in an in-plane direction and where one or more regions among the regions are periodically disposed.

    摘要: A lighting device includes: a first optical unit and a second optical unit. The first optical unit includes a primary light source and dichroic separation optics. The primary light source is configured to emit primary light in the visible spectrum. The dichroic separation optics are configured to intercept at least part of the primary light generated by the primary light source and emit, from a first emission surface, at least one first highly collimated light component and at least one diffuse light component. The at least one first highly collimated light component and the at least one diffuse light component forms a light with chromatic components having different angular distributions. The second optical unit includes secondary collimation optics is configured to generate, from the light with chromatic component, a weakly collimated light component and a second highly collimated light component.

    摘要: A light source module includes a first light source and a second light source. The first light source is configured for emitting a first light having a first wavelength, and the first light includes a first part and a second part. The second light source is configured for emitting a second light having a second wavelength. The second light source includes a first wavelength conversion layer, and the first wavelength conversion layer is configured for converting the first light into the second light. One of the first part and the second part is incident to the first wavelength conversion layer, and the other of the first part and the second part is not incident to the first wavelength conversion layer.
