  • Patent number: 8706310
    Abstract: A goal-based control system may be provided that controls lighting based on high-level management goals for the operation of a lighting system. The system may include a lighting system model. The system may convert the high-level management goals into low-level device control parameters that include a power level for each respective one of the light fixtures, where the system determines that a modeled operation of each respective one the light fixtures at the power level meets the management goals based on the lighting system model. The system may cause each respective one of the light fixtures to operate at the power level. The system may determine a likelihood of satisfying the management goals.

  • Patent number: 8690370
    Abstract: A control module having a plurality of control elements configured to control a first function of the control module in a first operating mode and another function of the control module in another operating mode of the control module. The control elements are grouped into different groups of control elements. Each group of control elements corresponds to a predetermined group of functions of the control module. The grouping is dependant on the operating mode of the control module. An illumination system provides illuminated control-dividing surfaces that visually separate one group of control elements from another group of control elements. The illumination system illuminates the control-dividing surfaces according to the grouping of the control elements and according to the operating mode.

  • Publication number: 20130335992
    Abstract: A compact passively-cooled solid state illumination system is provided as a replacement for conventional arc light, metal halide and Xenon white-light sources for photocuring applications. The solid state illumination system utilizes LED modules to generate high intensity light output suitable for photocuring. The light output is continuous in the visible spectrum from 380 nm to 530 nm and is suitable for photocuring using a wide range of photoinitiators. A touchscreen interface allows programming of spectral output, intensity and duration. Output can be initiated using the touchscreen interface and/or a foot pedal.

  • Patent number: 8562194
    Abstract: A wavelength conversion unit includes a wavelength conversion member that transmits a part of incident excitation light and converts a part of the excitation light into wavelength-converted light having a wavelength different from a wavelength of the excitation light to emit the wavelength-converted light. The excitation light has an intensity distribution in which an intensity is maximum at the center and decreases as getting apart from the center. A thickness of the wavelength conversion member at a portion into which light at the center of the intensity distribution of the excitation light enters is larger than those at any other portions.

The light diffusing optical fiber has a core and a cladding. The plurality of nano-sized structures is situated either within said core or at a core-cladding boundary. The optical fiber also includes an outer surface. The optical fiber is configured to scatter guided light via the nano-sized structures away from the core and through the outer surface, to form a light-source fiber portion having a length that emits substantially uniform radiation over its length, said fiber having a scattering-induced attenuation greater than 50 dB/km for the wavelength(s) within 200 nm to 2000 nm range.

  • Publication number: 20130242595
    Abstract: A solid state illumination system is provided as a replacement for conventional arc light, metal halide and Xenon light sources for applications in microscopy, fluorescence microscopy, and endoscopy. The illumination system includes hybrid optical and electrical control of output intensity in which the light output of one or more of the light sources is attenuated optically such that it is not necessary to reduce the electrical drive power/current of the LEDs at a level where the spectral power distribution is variable. One or more fixed, selectable, or variable neutral density filters is interposed in the output beam of one or more sources to achieve optical attenuation of the light output. The hybrid optical and electrical control of output intensity allows greater dynamic range of intensity to be achieved than could be achieved with electrical control of the LEDs alone while maintaining the desired spectral power distribution.
