Light assembly
An improved light assembly includes aligned directional light sources mounted one behind another. A distal one of the light sources occludes light emitted from a proximal one of the light sources. A reflector is interposed between the light sources, with a convex surface facing the proximal one of the light sources. Thus, the light assembly projects a light field extending at least through an 180° hemisphere, and up to about 270° backwards from the forward orientation of the light field, well-illuminating lateral approaches to the assembly.
TRIM ELEMENT COMPRISING TWO INDEPENDENT BACKLIT AREAS
A trim element having a coating layer defining an outer surface and an inner surface, the coating layer including at least two distinct backlit pattern areas separated by at least one opaque area preventing the passage of light from the inner surface to the outer surface. The trim element includes at least one light source for each backlit pattern area, the light source being fixed on the inner surface of the coating layer facing an opaque area while being spaced apart from the corresponding backlit pattern area. The trim element has one light guide per backlit pattern area.
Working light
The invention relates to a working light with glare reduction. The working light comprising at least one light source, at least one primary reflector element, which further comprises a lower edge, a first focus on the optical vertical axis y above a horizontal axis x and a second focus on an optical vertical axis y below the horizontal axis x. Further, the working light according to the invention comprises at least one secondary reflector element further comprising a secondary focus.
LIGHTING DEVICE WITH MOTORISED COLLIMATION CONTROL
A lighting device for professional illumination. The device includes a main housing having a front opening, a first light source, a first reflector configured to receive at least a portion of light emitted by the first light source and to reflect at least a portion thereof, and a second reflector configured to receive at least a portion of light reflected by the first reflector and to reflect at least a portion thereof. The lighting device is configured to emit at least a portion of light reflected by the second reflector out of the lighting device through the front opening. The lighting device further includes an actuator configured to move the first reflector or the second reflector in relation to each other in response to a predetermined control signal.
LASER/PHOSPHOR, LED AND/OR DIFFUSER LIGHT SOURCES WITH LIGHT RECYCLING
Apparatus and method using a recycling light source. The source includes: a laser, a phosphor plate and/or diffuser plate that receives laser light and outputs wavelength-converted and/or diffused light, curved reflective surface(s) that collect the output light and reflect the light back to the plate to increase brightness of output light. An optional heatsink and vibrator can be used. Some embodiments include a plurality of parabolic reflectors to image the plate to an output aperture in one of the parabolic reflectors. Some embodiments include a diffuser arranged to diffuse laser light at the diffuser, and a first curved reflector located and configured to reflect diffused light back toward the diffuser in order to preserve a brightness of the laser light. Some embodiments include a laser-excited phosphor light source and method with light recycling.
Illumination Devices Including Multiple Light Emitting Elements
A variety of illumination devices are disclosed that are configured to manipulate light provided by one or more light-emitting elements (LEEs). In general, embodiments of the illumination devices feature one or more optical couplers that redirect illumination from the LEEs to a reflector which then directs the light into a range of angles. In some embodiments, the illumination device includes a second reflector that reflects at least some of the light from the first reflector. In certain embodiments, the illumination device includes a light guide that guides light from the collector to the first reflector. The components of the illumination device can be configured to provide illumination devices that can provide a variety of intensity distributions. Such illumination devices can be configured to provide light for particular lighting applications, including office lighting, task lighting, cabinet lighting, garage lighting, wall wash, stack lighting, and downlighting.
Optical system
The present invention discloses an optical system comprising: a light source (1); a reflection hood (2); a shielding cone (3) arranged below the reflection hood (2); and a double focus lens (4) arranged between the light source (1) and the shielding cone (3).
Retroreflector method to prevent light pollution without energy absorption
This patent advances a technique for the use of retroreflectors to prevent light pollution while radiating electromagnetic energy away from an object. As such, the patent defines how to do this on a surface, on a solar panel and with a communication device. It further investigates the communication device and makes it useful for relatively ad-hoc communication systems where aspects of the source and destination locations, distances, orientations and detection equipment is not known ahead of time.

Compact optical system for a motor-vehicle passenger compartment
An optical system and an interior lighting device for a motor vehicle including a light source coupled to such an optical system. The optical system includes a first portion of an optical assembly that allows a real image of the light source to the enlarged and projected into proximity to a diffuser of the optical system. The optical assembly also includes a second portion that plays the role of a projecting optic to project out of the optical system a real image of the of the light source formed in proximity to the diffuser. The optical system allows a luminance of the light source of the interior lighting device to be decreased while preserving its pixelization, allowing light sources based on light-emitting diodes and driven with a high-amperage electrical current to be used in motor-vehicle passenger compartments without any risk to the occupants.
