A method of delivering light from a lighting device including having at least one main LED, at least one auxiliary LED, and at least one ceramic light conversion element placed longitudinal to the path of light emitted from the main LED and orthogonal to the auxiliary LED; the method including the steps of switching on the at least one main LED, and changing the color temperature of the light emitted from the lighting device by switching on the at least one auxiliary LED.

Method of illumination having light emitting device with ceramic conversion material

A lighting device including at least one conversion element and a least one LED, which emits light into the conversion element. The light is then converted and emitted with a high radiant flux. The at least one LED emits light in the wavelength range of &#x2267;220 nm to &#x2266;800 nm and the at least one conversion element converts at least part of the light from the at least one LED to light in the wavelength range of &#x3e;300 nm to &#x3c;1000 nm. In some embodiments, the at least one conversion element includes a ceramic conversion material.

Light emitting device with ceramic conversion material

Lighting systems, in particular used for SSTV, disco lights, lighting consoles and claviluxes. In order to reduce noise and to increase robustness, the system comprises a light beam source () arranged for generating a beam of light, a projection gate () arranged for controlling the beam of light, wherein the light beam source () is comprised of at least one light emitting diode, and the projection gate () comprises at least one liquid crystal (LC) optical element.

Dynamic lighting effect system

The invention relates to a system () for registering a vessel model with an image data set based on a joined model comprising a reference object model and the vessel model, the system comprising: a placement unit () for placing the joined model in a space of the image data set, thereby creating a placed joined model comprising a placed reference object model and a placed vessel model; a computation unit () for computing a deformation field based on a landmark displacement field comprising displacements of landmarks of the placed reference object model relative to corresponding landmarks in the image data set; a transformation unit () for transforming the placed joined model using the deformation field, thereby creating a transformed joined model comprising a transformed reference object model and a transformed vessel model; and a registration unit () for registering the transformed vessel model with the image data set based on modifying the transformed vessel model and optimizing an objective function of the modified transformed vessel model, wherein the objective function comprises a location-prior term based on a localization of the modified transformed vessel model relative to the transformed joined model. Hence, the system is arranged to model a vessel taking into account the localization of a vessel model relative to a reference anatomical structure described by a reference model.

Model-based coronary centerline localization

The present inventions concerns a display system () for displaying multiplex information, whereby an individual selection of information is individually addressed to a different user or user groups, whereby the display system for displaying multiplex information comprises at least one display panel of a plurality of light emitting dot-like means and a plurality of sensors (), whereby a user or user groups are located by sensor so that individual information can be individually addressed depending on the position of each sensor-located user or user groups.

Dancing guide floor using LED matrix displays

An illumination system (), comprising an illumination source () and a mechanical dimming device () for dimming the amount of light generated by the illumination source () and emanating from the lighting apparatus, comprising an array of partially overlapping blades, the array of blades being mechanically operable to define an optical passageway there through of variable cross sectional area, wherein each blade comprises at least one overlapping segment and at least one non-overlapping segment, the overlapping segments being a color filter and the non-overlapping segments being a shutter. In a preferred embodiment the color of the color filter is in the range from yellow to amber to red. This arrangement is especially useful with a high intensity lamp as the illumination source, and provides for natural dimming of the light produced by the illumination source over the range of from about 0 to 100% causing a color change in the projected light that resemble natural sunset.

Illumination system comprising mechanical dimming device

The invention relates to a halogen incandescent lamp for operating on line voltage, at least comprising a hermetically sealed, cylindrical bulb ( ) made from transparent material, a filling made from inert gas and a halogen additive, a luminous element ( ), a current supply system, and a mount ( ), which is formed from a single-piece support wire, one end region of which is bent away transversely to the lamp axis, and which retains the luminous element ( ) in the vicinity of the end of the bulb ( ) remote from the pinch, wherein a luminous element ( ) bent virtually into a U-shape is arranged symmetrically relative to the lamp axis, the luminous element ( ) is held twice by the mount ( ) in the region of the portion of the luminous element ( ) which is arranged transverse to the lamp axis, and one end of the mount ( ) is fixed in a pinch ( ).

Halogen incandescent lamp

An incandescent lamp with a low voltage burner (BM) and integrated voltage conversion means (VCM) having switching elements (Q1, Q2) driven by a separate control circuit (CC) comprising an integrated circuit (IC). The voltage conversion means are suitable for operation at a high temperature and causes only limited amounts of EMI.
