Abstract: A recessable luminaire (1) having a dome-shaped reflector (5), a lead-through hole (18) in a reflector side wall (14) and a light source carrier (6) carrying a light source (7), the light source carrier (6) being located at least partially outside the reflector (5) and the lead-through hole (18) being passed through by the light source carrier (6) or the light source (7) in such a manner that at least the light source (7) is located within the reflector (5). For simplification of the luminaire, the light carrier (6) is attached to the reflector (5) by means of direct connection with the outer side of the reflector (5).

Abstract: An elastomeric mat is formed by extruding transparent or translucent elastomeric material. Columns made of the same material guide light from an LED source directly to a light port on top of the column, and diffuse the light substantially throughout the column. A coating of opaque material is used to surround the length of the columns to prevent leakage of light. When mounted adjacent to a front panel, off-axis performance is substantially increased over the prior art by, in effect, bringing the light-emitting source adjacent to a clear port of the front panel. The columns of translucent or transparent elastomeric material function as light pipes, and are formed when making the eleastomeric mat. The columns may be cylindrical or rectangular. Either a rectangular or a cylindrical column of translucent or transparent elastomeric material can convey light to illuminate a legend printed directly on top of the column.

Abstract: An illuminating umbrella grip includes a cassette LED illuminating unit detachably mounted in a holder formed on the umbrella grip, with the LED illuminating unit operatively depressed for a constant or flashing illumination; and upon withdrawal of the LED illuminating unit from the umbrella grip, it may be operated to produce illuminating warning signal for safety purpose, or it may be replaced with a fresh LED unit as fully powered.

Abstract: In such a state that a self-vehicle runs along a guide route (YES in S6), if an intersection is not present in a forward part for a while (NO in S8), beam control is carried out in a navigation associating mode corresponding to the guide route (S9). Consequently, beam irradiation is properly carried out over a road provided ahead of the vehicle without requiring a complicated calculation for the beam control. On the other hand, if the intersection is present in the forward part of the guide route (YES in S8), the beam control is carried out in a normal mode (a control mode other than the navigation associating mode) (S10). Consequently, even if the self-vehicle gets out of the guide route when passing through the intersection, the beam control itself is performed continuously and the beam irradiation is properly executed over the road provided ahead of the vehicle.

Abstract: A generally spherical body having a plurality of flat, small reflective surface elements is supported for rotation about a horizontal axis within a housing having an opening. A light source and a mirror are disposed in the housing to reflect light rays from the light source onto the mirror then to the spherical body to cause the light rays passing through the opening in the housing onto an exterior wall to simulate descending snowflakes. The mirror is adjustable in order to change the path of the simulated snowflakes on the wall.

Abstract: Proper placement of a lighted area produced by light from a light emitting diode chip relative to a base provides for a lamp for use with conventional flashlights having a collimating reflector. At least a portion of the light produced by the light emitting diode chip then is collimated into a beam of light for projection from the flashlight. Various means are disclosed to provide for a radial distribution of the produced light wherein the produced light properly strikes the collimating reflector for concentration into the beam of light. Lens elements, scarification of an exterior surface and placement of reflective surfaces are all disclosed as examples of methods to provide for the desired distribution of light. Such methods may be used singularly or in various combinations.

Abstract: A vehicle cornering lamp capable of broadly irradiating a road surface ahead of and in an oblique direction of a vehicle while the vehicle is moving around a curve. The vehicle cornering lamp includes three reflector units 12A, 12B, and 12C, whose light emitting directions are respectively set to angles of 30°, 45°, and 60°, with respect to the traveling direction of the vehicle. The vehicle cornering lamp also includes a control unit 20 for controlling light emission—from the reflector units 12A, 12B, and 12C—according to the travel conditions of the vehicle. When the vehicle turns to the left at an intersection, a traveling road onto which the vehicle will turn left, and a road shoulder, are sufficiently irradiated by switching on the reflector units 12A, 12B and 12C in the order of 12A→12B→12C→12B→12A, so that pedestrians can quickly be detected.

Abstract: Since a light source lamp (11) and a reflector (12) of a lamp unit (10) are respectively fixed to a lamp housing (13) in a mutually independent manner, an attachment for attaching and fixing the light source lamp (11) is not necessary to be formed on the reflector (12) as an optical component, so that the shape of the reflector (12) can be simplified and accuracy of a reflection surface (121), especially at a bottom thereof, can be easily improved, thereby enhancing illumination of the lamp unit (10).

Abstract: An interface apparatus provides a sterile barrier between a sterile field and non-sterile portions of an associated surgical lighthead. The interface apparatus is a sterile disposable cover including a lower grippable portion, an intermediate cone-shaped portion, and an upper window area. The lower grippable portion is adapted to connect onto the handle portion of an associated surgical lighthead. An intermediate cone-shaped portion connects the lower grippable portion with an upper window area. The upper window area overlays control input means of the associated surgical lighthead such as, for example, light intensity controls. At least a portion of the upper window area is transparent to enable visualization of the control inputs beneath the sterile disposable cover. The interface apparatus is of a unitary or composite construction.

Abstract: A polarization splitting backlight module for efficiently converting a non-polarized light beam emitted from the light source into a single polarization state is disclosed. The polarization splitting backlight module of the present invention comprises an under plate with a ridged lower surface, a light source, a special reflection film, a scattering structure, a substrate and a polarization splitting film. The light beam emitted from the light source is introduced into the scattering structure between the under plate and the substrate. After a series of processes, such as scattering, reflection, phase retardation and polarization beam-splitting, the light beam will pass through the polarization splitting film being of a single polarization state such that it could be utilized by electro-optical systems, such as liquid crystal displays. The present invention converts light beams into a single polarization state, and the efficiency thus is higher than that of a conventional backlight module.
