  • Patent number: 10322964
    Abstract: A method for producing a reflector on a reflector base made of glass is provided. According to the method, a metal-containing coating fluid is deposited on a coating surface and subjected to a burning-in treatment at a temperature below a softening temperature of the glass forming the reflector layer. Deposition of the coating fluid proceeds using a contactless method by inkjet technology. This makes it possible to deposit a reflector layer in a reproducible way and with tight tolerances having a specified layer thickness, as well as to create clean edges without a printing block or similar device. The coating fluid is moved by a print head equipped with a plurality of nozzles and is movable in a movement plane relative to the coating surface. The coating fluid is sprayed onto the coating surface by the print head under pressure and in the form of droplets emerging from the nozzles.

    Abstract: The invention discloses an outdoor luminaire. The outdoor luminaire comprises a light module comprising at least one LED unit; wherein said light module is configured such that the light emitted by the light module has a first luminous intensity value no less than 10 cd/klm at a first angle (?i), which is a vertical angle of 90 degrees above a direction pointing directly downward from the luminaire. In this way, the luminous intensity of the outdoor luminaire at a vertical angle of 90 degrees is guaranteed to be no less than 10 cd/klm Since the end user sees the light 710 emitted at a vertical angle of 90 degrees no matter how far away he is from the outdoor luminaire, the end user always perceives a certain level of brightness. Such “certain level of brightness” is helpful in increasing the adaptation level of the end user, and can effectively reduce the end user's perception of glare.

    Abstract: An apparatus, system and method for glare reduction and effective lighting, including uplighting for such things as sports fields including golf courses or for other large area projects. A set of solid state light sources having an original perceived intensity from viewers and an original light output, are altered to be perceived by a viewer as a larger light source to reduce glare to the viewer. This alteration can occur when a number of techniques including diffusive or reflective surfaces in the original output of the light sources. Altered light output is further modified by either cutting portions of it off or redirecting portions of it for more effective use. For example, a visor with reflective surface can redirect light either to a target area or for uplighting. This allows concurrent benefits of glare reduction for viewers of the sources or effective use of light.

    Abstract: A light concentrator assembly includes a concentrator portion having multiple light concentrators. The light concentrator assembly concentrates light received from different parts of a light source, such as a light emitting diode, and outputs light beams that have an angular spectrum narrower than the light beam received from the light source. Each concentrator of the light concentrator assembly concentrates light from one or more parts of the same light source. Light can optionally be routed from the different parts of the light source to different ones of the multiple light concentrators using multiple angular rotators that maintain the angular spectrum of the light output by the different parts of the light source.
