Abstract:
The invention provides a lighting system (1) with at least two subsets (SS1, AS1) of light sources, wherein one or more first subsets (SS1, SS2,…) provide first light (111) mimicking the solar light (during the day) and with the first light (111) having a variable direction, and wherein one or more second subsets (AS1, …) provide second light (211) mimicking the sky (without the sun, as the sun is provided by the first subset(s)) 5 (during the day). Especially, the color and/or color temperature of the first light (111) is variable, in addition the variability in direction. The lighting system may further comprise a control system (20) configured to control the color and intensity of the first light and/or second light.
Abstract:
A lighting device (26) for a vehicle cabin (10) is described. The device (26) comprises at least one light source (56), a blending lens (28) and a diffusing lens (30). The light sources (56) are configured to transmit light to the blending lens (28). The blending lens (28) is configured to receive light from the at least one light source (56) and transmit blended light to the diffusing lens (30). The diffusing lens (30) is configured to receive blended light from the blending lens (30) and transmit diffused light into the vehicle cabin (10).
Abstract:
A decorative lighting apparatus including at least one light source and an attenuation assembly. The attenuation assembly including an attenuator, a first housing being configured to be coupled to a second housing, and a first base being configured to be coupled to a second base. When the first housing is coupled to the second housing, the first and second housings form a recess designed and dimensioned to receive and hold the attenuator in a substantially fixed position, and when the first base is coupled to the second base, the first and second bases form a further recess designed and dimensioned to receive and hold the coupled first housing and second housing in a substantially fixed position.
Abstract:
An environmentally friendly method and device to eliminate insect pests utilizing lighting, sound, pheromones or scents, alone or in combination. This present invention to remove pests avoids the expense of biocide technologies that have not been developed fully, the damage to people and the environment from the use of dangerous chemical pesticides, and add to sustainable agriculture efforts including integrated pest management.
Abstract:
A lighting system includes at least one solid state light adapted to replace a lamp in a fluorescent lamp fixture, and a power supply configured to convert power drawn from the fluorescent lamp fixture to power the at least one solid state light. The power supply includes a rectifier, a voltage regulator, a power output for the at least one solid state light, and an auxiliary DC power output. The power supply is configured to generate a regulated DC voltage at the auxiliary DC power output based on the power drawn from the fluorescent lamp fixture.
Abstract:
Système optique 100 configuré de sorte que la relation entre l'angle d'incidence et la distance d'émergence du rayon optique émergent par rapport à l'axe optique principal O-Osoit proportionnellement décroissante de sorte à mélanger les couleurs de façon homogène ainsi qu'une surface émergente texturée pour uniformiser l'homogénéisation de la synthèse additive. L'image de la source de lumière901est uniformément homogène et décorrélée de sa forme.
Abstract:
In an example embodiment, there is disclosed herein an airfield lighting system that employs an IR emitter. The IR emitter can be located within an airfield lighting fixture or external to the lighting fixture. Activating the IR emitter can enable an Enhanced Flight Vision System ("EFVS") to determine the location of lighting fixtures which may be undetectable by the EFVS, such as Light Emitting Diode ("LED") fixtures.
Abstract:
A flexible and illuminating multilayer structure wherein the flexible and illuminating multilayer structure (10) comprises at least two flexible foils (100, 102) laminated together. Each foil (100, 102) has a flexible electrically conductive pattern layer (104) and LED units (106) distributed over the foil (100, 102), the LED units (106) being electrically contacted with the contact pattern (104). The LED units (106) of a foil (100, 102) are positioned between positions of the LED units (106) of the other foils. At least one foil of the multilayer structure (10), towards which at least one of the LED units (106) is configured to radiate light, is transparent to the light. Brightness of the LED units (106) is at least foil- specifically controllable with operational electric power fed to the foils (100, 102) through the contact pattern (104). The LED units (106) of at least one foil (100, 102) are of a different tone or color or are controlled to output a different tone or color than the LED units (106) of at least one other foil (100, 102).
Abstract:
A lighting device is disclosed, which comprises a light transmitting element extending along a perimeter such that a hollow is defined by the light transmitting element. The light transmitting element comprises a light in-coupling surface adapted to couple light emitted by at least one light emitting element into the light transmitting element, and a light out-coupling surface adapted to couple light out of the light transmitting element. The lighting device is combined with a light reflecting envelope arranged to enclose the lighting device such that light emitted from the light out-coupling surface is reflected at an inner surface of the envelope. Thereby a reflected image may be produced, having an appearance resembling a candle flame.
