Abstract:
The disclosure generally relates to efficient hollow light duct bends (200) that are capable of retaining a higher on-axis transmission for partially collimated light propagating within a light duct (220, 230). In particular, the described hollow light duct bends (200) include input and output plates (214, 216) that have low reflectivity for near normal incident light, and high reflectivity for near grazing incident light.
Abstract:
A lighting module may be provided that includes: a first and a second light source units which are disposed to face each other; a first case in which the first light source unit is disposed; a second case in which the second light source unit is disposed; a first plate of which one side is connected to the first case, of which the other side is connected to the second case and which includes a first hole through which light emitted from the first and the second light source units passes; a second plate which is disposed to face the first plate and includes a second hole through which the light emitted from the first and the second light source units passes; and a first and a second optical sheets which are disposed on the first and the second plates.
Abstract:
The invention relates to a light-output device (1; 10; 30) controllable to provide different light-output functions. The light-output device comprises a light-source arrangement (12; 31) configured to emit light; and a light-guiding system (10; 32) arranged to receive the light and configured to guide the light to at least one light-output surface of the light-guiding system. The light-guiding system (10; 32) comprises at least a first light-guide (11b; 37) and a second light-guide (11a; 40, 41); and the light-guiding system (10; 32) is movable relative to the light-source arrangement (12; 31) between at least a first position where light output by the light-source arrangement is guided by the first light-guide (11b; 37) to provide a first light-output function, and a second position where light output by the light- source arrangement is guided by the second light-guide (11a; 40, 41) to provide a second light-output function, different from the first light-output function. The present invention is based on the realization that different light-output functions conveniently and intuitively can be achieved by moving a light-guiding system comprising at least two light-guides relative to a stationary light-source arrangement. Hereby, different light-output functions can be achieved with a single stationary light-source arrangement.
Abstract:
The present invention relates to a solar lighting assembly in which large amounts of sunlight are led into a dark room or underwater so as to achieve relatively efficient solar lighting by using a light-transmitting means and/or light-transmitting pipe of large internal diameter and a reflecting mirror, and in which efficient light dispersion is achieved by using reflecting mirrors of various configurations, and which is adapted to be usable even underwater as complete watertightness is maintained.

Abstract:
A light guide device for transmitting light through a column of light transmitting medium and into an adjacent culture growing solution, including a barrier structure for separating the medium and solution, the barrier structure being light transmissive to allow for extraction of light and being adapted to hold a material of reduced refractive index relative to the medium so as to provide total internal reflection for light incident the barrier structure at greater than a critical angle to thereby guide the light through the device.
Abstract:
A beam combiner assembly (150) for a night vision device is disclosed. The beam combiner assembly is for use with a night vision device. The beam combiner assembly includes a beam combiner (250, 256, 258) and one or more light pipes (290). The beam combiner is configured to generate a combined image by combining a first image and a second image. The beam combiner is further configured to transmit the combined image to a user. The one or more light pipes are coupled to the beam combiner in positions corresponding to one or more indicator lights. Each light pipe is configured to receive light from a respective indicator light. Each light pipe is further configured to transmit the light from the respective indicator light to the beam combiner. The beam combiner assembly may be provided in a night vision device including a first image source, a second image source, a microdisplay (230, 232, 234), and a display connector.
