  • Patent number: 10466404
    Abstract: A primary optic for a light-emitting diode or device (LED) includes a tilted wedge atop a truncated compound parabolic concentrator (CPC). The CPC includes an input face and a lower exterior surface defined by a tilted parabolic segment rotated about an axis. The bottom end of the lower exterior surface joins the perimeter of the input face. The tilted wedge includes an upper exterior surface above the lower exterior surface, and an interior conical surface surrounded by the lower and the upper exterior surfaces. The upper exterior surface is defined by a tilted straight line rotated about the axis. The interior conical surface is defined by a smooth curve rotated about the axis. The interior conical surface has a vertex located at the axis and within the lower exterior surface. The top ends of the interior conical surface and the upper exterior surface join to define an output aperture.

  • Patent number: 10429563
    Abstract: A light source socket is detachably attached to a housing of a vehicular lamp, and the light emitted by an LED on the light source socket is incident on a light-incident portion of a light guide to be guided to a light-emitting portion. The light guide is held by a pair of holding members at a predetermined position of a lamp housing via a reflector. Positioning portions configured to sandwich the light-emitting portion therebetween are formed on the holding members, respectively, and the light-incident portion is held at a fixed position with respect to the LED. The LED is surrounded by light-shielding walls of the holding members, and the light emitted to the periphery of the light-incident portion is returned to the light-incident portion by reflective films of the light-shielding walls.

In particular, a Digital Signage Control System (“DSCS”) facilitates delivery of sensor command parameters to particular signage devices or a network of signage devices as specified in a Sensor Command Deployment Plan. After receiving various sensor commands from a user at a user interface, a Sensor Command Deployment Module generates a Sensor Command Deployment Plan (“SCDP”), which specifies which sensors or controls should be adjusted on signage device(s) and when the adjustments should be made. Subsequently, a Signage Communication Module (“SCM”) waits for a request for sensor instructions from a signage device specified in the plan. Once the request is received, the SCM deploys specific instructions or commands (parameters) to a particular signage device wherein the command is executed at the signage device.

  • Publication number: 20140347877
    Abstract: The invention relates to decorative elements for a car. The aim of the proposed invention is to increase the effectiveness of illumination. The invention is realized as follows. A basic element with an external surface and with a first internal surface, a translucent element with a second internal surface and with a connecting surface, and light sources, for example in the form of an electro-luminescent conductor, are manufactured, as is an attachment means, if required. The light sources are arranged between the basic element and the connecting surface, for example, in a specific case, in a groove formed in the translucent element. The translucent element is connected by the second internal surface to the first internal surface with the aid of an attachment means, for example, an adhesive substance, or by any other method suitable for this field.

  • Publication number: 20140286048
    Abstract: The present invention relates to a switchable see-through luminescent system, e.g. for luminous signage, characterized by its mode to exist in two different states, transparent (‘off-state’) and luminescent (‘on-state’), due to the presence of a luminescent material (20), coated on to the transparent surface (10), capable of being excited on command by means of lighting sources (30) (e.g. LEDs) characterized by suitable emission spectra. In the off-state of the luminescent material (20), the surface appears transparent and it is not evident any significant modifications of the optical properties (transparency, color, etc.) of the surface.

  • Publication number: 20140240954
    Abstract: A strip lighting device includes a main body having front and rear sides extending along a length of the main body. The front side is disposed towards a viewer of the device and the rear side includes a light scattering layer for scattering light from a source of illumination towards the viewer when the device is illuminated. The main body has a front and rear cladding layer each of which is made of a first light transmissive material. The strip lighting device includes a light pipe made of a second light transmissive material sandwiched between the front and rear cladding layers at interfaces extending along the length of the main body. A rear interface of the light pipe has a plurality of angled portions which allow some light to escape into the rear cladding layer to impinge on the light scattering layer and scatter light towards the viewer.

  • Patent number: 8807788
    Abstract: An information display device illuminates a light pipe, and includes a controller to regulate the power levels delivered to a light source, thereby regulating the amount of light delivered to the light pipe. Alternatively, the information display device delivers visual data, including alpha-numeric characters, predetermined images, or a controlled phasing. The information display device may be utilized to illuminate information associated with the structure. The illumination system provides the ability to phase between different colors, as well as blended colors. Accordingly, an information display device phases between varying colors, and may blend colors to create color schemes. The illumination system includes a control module disposed within the structure to control device parameters.
