Abstract: Lighting devices for providing a secondary light with high luminance are provided. The lighting devices include a light conversion element and a light emitting unit with a light source that emits a primary light. The light conversion element has a front side illuminated with the primary light and, in response to the primary light, to emit a secondary light from the front side. The secondary light has a larger wavelength than the primary light.
