Abstract:
A method for retrofitting a lighting system includes providing a lighting assembly with a screw-terminal-base connector disposed in a lamp housing. A power-supply conductive wire includes a second length coupling the screw-terminal-base connector to a transformer and a first length coupled to the transformer and coupleable to a power supply. The first and second lengths of the power-supply conductive wire are severed and the transformer is removed. The severed first and second lengths are spliced together. An Edison-base receptacle is mounted to the lamp housing. The second length of the power-supply conductive wire is electrically coupled to the Edison-base receptacle.
Abstract:
A white color light source of an organic light emitting diode is provided and is suitable for irradiating on plants. The white color light source includes a first color light and a second color light. A peak in the frequency spectrum of the first color light is within a first wavelength range. A peak in the frequency spectrum of the second color light is within a second wavelength range. The white color light source is at least formed by mixing the first color light and the second color light, wherein an intensity of a frequency spectrum of a wavelength range from 520 nm to 580 nm is substantially equal to or less than 20% of a total intensity of a frequency spectrum of the white color light source.
Abstract:
A reaction-testing system is provided to simulate motion to an individual. Generally, the reaction-testing system includes a motion-simulating device, a reflective device, a control unit, and an input device that is activated by an individual In exemplary embodiments, the motion-simulating device includes a beam that accommodates a first and second plurality of light sources capable of, at least, alternating between an active and idle condition. These light sources are arranged amongst occlusion features in a mounting pattern such that light emitted from the first plurality is directly viewable by an individual and light emitted from the second plurality is indirectly viewed by the individual through the reflecting surface. The control unit is configured to sequentially activate the light sources sequentially to generate pulses of light on that, when perceived by the individual, appear as a light moving along a vector.
Abstract:
An electronic device includes a case, a multi-directional input unit having an annular base and a flange that extends from an outer circumferential surface of the annular base and fits part of the case, the flange guiding light emitted from a light source and radiating the light; and a cover having a through-hole through which part of the multi-directional input unit passes, the cover abutting the flange and being secured to the case.
Abstract:
A light emitting device of the present invention includes a light-emitting section for generating fluorescence by receiving a laser beam, and a light irradiation unit for irradiating a light irradiated surface of the light emitting section with a laser beam that increases regularly in beam diameter in a direction in which the laser beam travels.
Abstract:
A lighting device includes: a first light source group having first light sources partitioned into sections and controlled to light for each section; and a second light source group having second light sources partitioned into sections and controlled to light for each section. The second light source has a light distribution different from the first light source. The first and second light source groups are allowed to light independently of each other. The first light sources are arranged in a first array pattern allowing a uniform in-plane-distribution of luminance at a predetermined distance therefrom when whole of the first light source group is under lighting condition. The second light sources are arranged in a second array pattern different from the first array pattern. The second array pattern allows a uniform in-plane-distribution of luminance at the predetermined distance therefrom when whole of the second light source group is under lighting condition.
Abstract:
A lighted background for mounting on a wall of an aquarium fish tank or the like includes a front panel having an image formed thereon. Light apertures are formed through the front panel and lighting is provided behind the panel to direct light through the apertures. Translucent material covering the apertures and reflective material behind the lights enhances the lighting effect.
Abstract:
The invention relates to a device for illuminating organic objects, particular organic objects of the eye. Preferably, the device can be used in an opthalmological diagnosis or therapy device. According to the invention, an array of miniaturized light sources is arranged in a spatially defined manner on a plane or a curved surface such that the light sources achieve a packing density that is as high as possible and can be electronically controlled individually in a very quick manner. The light source array is imaged onto the biological object by means of an optical system.
