This is accomplished by individually controlling each light-emitting element of a linear array of light elements. Calibration of the array is accomplished by sequentially illuminating each optical element of the source and building an array of normalized detected data. The matrix is then inverted and multiplied by a linear array of ones to generate the calibration data. The calibration data are then used to program a simple logic device that allows accurate digital control of the intensity of each individual light element.

Critically, the body fits over the flash tube only, thereby leaving the modeling light unobstructed. It its preferred embodiment, the filter device has axial symmetry. It a most preferred embodiment, the filter device has a circularly shaped base, a tubular sidewall that extends from the base to an enclosing top section. The top section critically includes an aperture through which the modeling light will project, when the filter device is placed upon a photo strobe unit.

  • Patent number: 6601972
    Abstract: In a deuterium lamp box in accordance with the present invention, a wavelength of light different from that of a deuterium lamp can be forwardly let out from a light exit opening. Namely, when the deuterium lamp of a see-through type is lit, the light generated from the deuterium lamp can be let out from the light exit opening. When a second lamp is lit while the deuterium lamp is turned off, the light generated from the second lamp 85 passes through the deuterium lamp while in a state collected by a lens, and is let out from the light exit opening. When the deuterium lamp and the second lamp are lit at the same time, different wavelengths of light are let out from the light exit opening while in a mixed state. Thus, three kinds of light can be made depending on how the lamps are lit, whereby this lamp box is considered to have a versatility much higher than that of a lamp box accommodating only one lamp.

    Abstract: A white light is provided for backlighting a liquid crystal display by directing red green and blue light into the first end of a color mixing optical fiber, mixing the red green and blue light in the color mixing fiber to produce white light, and conducting the white light out of the second end of the color mixing fiber to the liquid crystal display. The color mixing optical fiber and sources for generating the red green and blue light may be located remotely from the liquid crystal display, and the white light produced in the color mixing optical fiber coupled to the liquid crystal display by coupling optical fibers, thus simplifying and facilitating construction and operation of the backlighting system, and allowing for more convenient removal of heat remotely from the liquid crystal display.

  • Patent number: 6558015
    Abstract: A lamp assembly for general illumination and/or ornamentation has a base with a support member bearing both a lamp-bulb receiving socket and a lamp shade. The lamp shade, or other ornamental element of the lamp assembly is formed at least in part of an electroluminescent material and, in the disclosed form, the inner surface of the shade is reflective. The lamp assembly, accordingly, includes two sources of illumination, namely the electroluminescent material and a lamp-bulb received in the bulb-receiving socket. A conventional line cord is provided to connect the lamp to any ordinary source of electrical power, and a four-position electrical switch coupled to the line cord permits a user to direct power selectively to the lamp socket, or to the electroluminescent shade, or to both simultaneously. In its fourth position, all electrical power is cut-off so that the lamp is not illuminated.

    Abstract: An electrically powered illuminating handle/strap for lifting, pulling, carrying, opening, holding or whatever. The light source is the handle/strap. Illumination can occur in different ways by aiming the light emitting means. Directions can be: generally, as in all directions; partially, such as drown into a container, at what it is attached to, or towards the person using it; specifically, such as at signage or a keyhole on or adjacent to what it is attached to; or in a combination of several directions at once. Different or combinations of light emitting means can be used. The handle can be rigid or flexible. This is a simple cost effective way to increase visibility and safety.
