Abstract:
Lighting apparatus is provided comprising a light source (10), the light source being encapsulated in a protective medium (11) to seal the light source against ingress of moisture, the lighting apparatus having a heat sink (12, 13), the heat sink having a first region (12) in communication with light source (10) to receive heat from the light source (10) and a second region (13) which projects externally of the protective medium, such that the heat sink can dissipate heat to the ambient area. The invention provides light apparatus which is particularly suitable for use with caving lamps, although other uses are possible, for example in traffic lights or the lights of a motor vehicle, where the encapsulation would provide protection against rain.
Abstract:
The aim of the invention is to produce an easily readable display device (5) for a transmitter element (1). To this end, one corner on the housing (3) of a transmitter element (1) is configured in the form of a display device (5). Parts of the direct light in a first beam direction (23) of an LED are deviated in different directions by means of two integrated reflectors (11) which are located beneath the outer wall (9) of the body (7) that is shaped in the form of a housing corner.
Abstract:
The invention relates to an aircraft beacon device installed on a high structure, preferably on a tower of a wind power installation, and comprising a least one luminous means and at least one switching device that switches said luminous means. The aim of the invention is to improve an aircraft beacon device of wind power installations and, in particular, to design the operation thereof to be as effective as possible. To this end, the aircraft beacon device installed on a high structure, preferably on a wind power installation, and comprising at least one luminous means mounted on the structure is provided with a device for detecting the brightness value, e.g. a twilight switch. Said device for detecting the brightness value detects the brightness of day in the surroundings of the structure and is connected to a switching device, which evaluates the measured data and switches on the aircraft beacon when a defined brightness value is fallen below of.
Abstract:
The invention relates to a light-emitting diode array that is surface-mounted on a board (1), such as a flexible board. The light-emitting diode array is mounted on a heat sink (3), so that the heat can be dissipated in an optimal manner. Said heat sink can take any form desired so that it is possible to design motor vehicle lamps, such as indicator lamps or similar, that can be adapted to the outer contour of the vehicle. In the case of a rotating lamp, the board (1) can be mounted around a heat sink that is configured as a cylindrical hollow body and can be operated rotationally.
Abstract:
The invention relates to a combination of a light-emitting tubular device (25) and a support pillar (15) for retaining and electrically connecting the device, the light emitting device comprising a translucent outer sheath comprising braided filaments (8) and a light emitter (2) arranged within the tubular hollow body (1), the combination comprising retaining hooks (20, 36, 41) for retaining the device in the pillar, and power connectors (19, 26, 38, 43) for connecting the device and the pillar and providing power to the light emitter. The invention also relates to a light emitting device and a pillar for mounting the device with purposes of delimiting pedestrians walking areas, performing towing functions, rescuing activities, signaling.
Abstract:
A visual signaling device has one or more light source modules (10). Each module (10) is of "Tri-liptic", i.e., generally triangular shape, but with the triangle corners rounded. Inside the triangle, is a perfect circle, to aid in the optical dispersion of the light source (74). The modules are each formed by back (18, 20) and front moldings (22). The light source module (10) contains light source (26) on a printed circuit board (70). This module also contains the electronics causing light source to flash, be illuminated constantly or a reflector to rotate around a stationery bulb (74). A conduit (60), which is a strip of printed circuit board with connectors at its opposite ends, extends between the top and bottom of each module of the stack. The board containing the light source is inserted via guides (76) into another connector which is attached to the conduit. The light source module (10) may readily be removed and may be interconnected into a stack by connection of the tops and bottoms of the back moldings of adjacent modules in the stack by means of interlocking projection and slots (36, 38). A cover (14) and a base (12) may be connected to the topmost and lowermost modules of the stack. The base may contain an audible warning source (82). The connection of the modules in the stack does not require separate rods or screws which extend through the entire stack.
Abstract:
The invention relates to a luminous element, especially for illuminating function symbols or indicating functions in automobiles, comprising a housing (3) for installing the luminous element (1) in an assembly part (15) accommodating at least one luminiferous element (7) and at least two contact elements (5), also accommodated in the housing, for connecting the connecting contacts of the at least one luminiferous element (7). Each contact element (5) has longitudinal slots (23), each accommodating at least one connecting contact (7b, 27a) of the at least one luminiferous element (7) or one additional electronic component (27).
Abstract:
An escape route signalling system for installations is disclosed, in particular for buildings, constructions, skyscrapers, large meeting halls, underground stations, shopping centres, tunnels, industrial complexes, museums, department stores, airports, hotels or ships, by means of escape route signalling. The escape route signalling is a luminous strip (10).
Abstract:
A mirror assembly (10) including a dichroic mirror (50) which allows a predetermined narrow spectral band to pass through the mirror and be seen from a position forward of the mirror (50), and which further reflects a broad spectral band of light which originates from a direction forward of the mirror; a light source (62, 76) is positioned rearwardly of the mirror (50) and emits light in the predetermined narrow spectral band passed by the dichroic mirror; and an electronic circuit is provided which is operable to step up, or step down the voltage supplied to the light source thereby maintaining a constant voltage source which is utilized to energize the light source (62, 76).
Abstract:
A mirror assembly (10) including an enclosure (50) having an aperture (44), and defining a cavity (60), a light source or lamp (70) for emitting light in predetermined wavelengths or an instrument for emitting or receiving light having predetermined characteristics, borne by the enclosure and positioned in the cavity; and a dichroic mirror (110) borne by the enclosure and disposed in substantially occluding relation relative to the aperture, the dichroic mirror reflecting ambient visible light and being substantially transparent to the light emitted by the light source and instrument, or received by the instrument as the case may be.
