Disclosed is a dock light assembly for illuminating a trailer interior. The dock light assembly may include a cylindrical housing having an illumination source therein, and an optical lens secured to an end of the housing. The optical lens may be configured to provide focused illumination to the trailer interior. A rotationally self-correcting screen device may be positioned between the illumination source and the optical lens. The screen device may be configured to absorb a portion of the focused illumination such that illumination to an upper portion of the trailer interior is reduced. The rotationally self-correcting screen device remains in a horizontal orientation even if the housing is rotated. One benefit of the disclosed dock light assembly is that forklift operators working in the trailer interior are shielded from high intensity light, even though the lower portion of the trailer interior remains brightly lit.

The present disclosure describes light delivery and distribution components of a ducted lighting system having a cross-section that includes at least one curved portion and a light source. The delivery and distribution system (that is, light duct and light duct extractor) can function effectively with any light source that is capable of delivering light which is substantially collimated about the longitudinal axis of the light duct, and which is also preferably substantially uniform over the inlet of the light duct.

An exterior aircraft light unit includes a mounting structure, an LED arranged on the mounting structure, and an optical system, arranged on the mounting structure for creating an output light emission distribution of the exterior aircraft light unit. The optical system has, in a first cross-sectional plane extending through the LED, a first concave reflector and a second concave reflector, each of the first and second concave reflectors having a proximate end positioned adjacent to the mounting structure and a distal end positioned removed from the mounting structure, with the first and second concave reflectors being arranged on opposite sides of the LED in the first cross-sectional plane, and a refractive optical element arranged between the first and second concave reflectors in the first cross-sectional plane. The distal ends of both the first and second concave reflectors that curve towards each other and have back-tapered shapes.

The invention relates to a mirror assembly (1) for producing a plurality of beam bundles (K1, K2, . . . Kn) from the beam of a light source (L), wherein the plurality of beam bundles comprises at least one first beam bundle (K1) having a first main beam direction (SR1), a second beam bundle (K2) having a second main beam direction (SR2), and preferably further beam bundles (K3 . . .

An illumination system including at least one light source, a reflection cover, a wavelength conversion element, and a filter element is provided. A focal point of the reflection cover is disposed on an extension line of a transmission path of an excitation beam provided by the light source, and an opening of the reflection cover is adjacent to the focal point. The wavelength conversion element penetrates through the opening, and has a light-action region. The light-action region is disposed on the transmission path of the excitation beam, and converts the excitation beam into a conversion beam. The reflection cover is disposed on a transmission path of the conversion beam. The filter element is disposed on a transmission path of the conversion beam from the reflection cover. The conversion beam from the reflection cover is obliquely incident to the filter element, and the filter element filters the conversion beam.
