In order to suppress the chromaticity shift and corrosion associated with the deterioration of a sulfide phosphor particle, this phosphor sheet is produced using a phosphor particle-containing resin composition which comprises: covered phosphor particles; polymerizable compound; and a polymerization initiator. The covered phosphor particles are obtained by covering phosphor particles with silicon dioxide films, wherein among the phosphor particles, at least sulfide phosphor particles are covered with silicon dioxide films that contain a metal oxide powder. Thus, the phosphor sheet can be inhibited from emitting a sulfur-based gas, and exhibits a minimized chromaticity shift, even when the phosphor sheet is present in such a manner that the edge of the phosphor layer of the sheet is in an exposed state.

Apparatus and methods for lighting. The apparatus may include an LED light source. The light source may be disposed in housing. The apparatus may include a circuit. The circuit may be configured to cause the LED light source to emit light at: a first intensity; and a second intensity that is different from the first intensity. The apparatus may include a mechanical power state selector. A user may use the power state selector to select between LED light sources that are arranged to illuminate in different directions. The apparatus may include a CCT state selector. A user may use the CCT state selector to select a CCT for one or more LED light sources. The CCT may be produced by combining light from one or more LEDs of different CCTs.

An optical component made of synthetic quartz glass includes a glass structure substantially free of oxygen defect sites and having a hydrogen content of 0.1×10.sup.16 to 1.0×10.sup.18 molecules/cm.sup.3, an SiH group content of less than 2×10.sup.17 molecules/cm.sup.3, a hydroxyl group content of 0.1 to 100 wt. ppm, and an Active temperature of less than 1070° C. The optical component undergoes a laser-induced change in the refractive index in response to irradiation by a radiation with a wavelength of 193 nm using 5×10.sup.9 pulses with a pulse width of 125 ns and a respective energy density of 500 μJ/cm.sup.2 at a pulse repetition frequency of 2000 Hz. The change totals a first measured value M.sub.193 nm when measured using the applied wavelength of 193 nm and a second measured value M.sub.633 nm when measured using a measured wavelength of 633 nm. The ratio M.sub.193 nm/M.sub.633 nm is less than 1.7.

An emblem assembly is provided that includes a power source, a backing member, and a light-producing assembly coupled to the power source and supported by the backing member. The light-producing assembly may include an electroluminescent light source. The emblem assembly further includes a chromatic layer over the light-producing assembly that comprises and emblem shape, and a translucent sealing structure over the chromatic layer that seals the backing member, the light-producing assembly, and the chromatic layer. The emblem assembly exhibits a chrome- or mirror-like finish when viewed under ambient lighting conditions. Further, the emblem assembly possesses a glowing appearance when activated under low light or nighttime conditions.

A vehicular lamp includes a light source; and a light guide disposed such that light emitted from the light source is incident on an end face of the light guide. The light guide emits light, guided into its interior, heading vehicle-forward from an exit face of the light guide running along the light guide's lengthwise extension. The light guide includes reflection steps formed on a surface of the light guide on a side reverse from the exit face, for reflecting light guided into the light-guide interior toward the exit face; and a plurality of diffusion flutes formed on said end face, each being arcuate in substantially horizontal cross-section through said end face, and each being of constant form in substantially perpendicular extension.

A fiber optic connection inspection apparatus and method includes an adapter housing fitted to a video microscope camera configured to observe and records images of a Direct Contact and Expanded Beam fiber optic connector assemblies. The adapter housing is configured to rotatably connect the camera for 360 degree rotation about a longitudinal axis of the adapter housing, assuring inspection of a larger field of view. The field of view represents the three-dimensional nature of the various sectors of a fiber optic connector. The rotation of the camera permits the instrument to visualize the complete connector, enabling the technician to make an informed decision which surfaces to clean to improve signal transmission. The adapter housing may be constructed of soft material that enables camera manipulation to provide a comprehensive view of the optical connector surfaces. The rotating adapter housing may be 3D printed which enables flexibility of design and production.

Industrial lighting device including a light source and a sealed housing containing the light source. The housing includes a support delimiting a housing window extending opposite the light source, a window pane sealing the housing window, and a sealing gasket extending along the periphery of the housing window and compressed between the window pane and the support. The device includes a filter extending in front of the housing window, outside the housing. The filter includes a frame defining a frame window which is removably fixed to the housing, in an assembled position in which the frame window is opposite the housing window, and an optical film fixed to the frame and sealing the frame window. The device includes an elastic compression member arranged between the support and the frame.

Vehicular lamp furnished with: a first light source emitting blue laser light having a peak wavelength in a wavelength region of 450 nm to 470 nm; a second light source emitting green laser light having a peak wavelength in a wavelength region of 510 nm to 550 nm; a third light source emitting red laser light having a peak wavelength in a wavelength region of 630 nm to 650 nm; a phosphor that by being excited by a portion of the blue laser light emitted by the first light source or of the green laser light emitted by the second light source emits excitation light having a peak wavelength in a wavelength region of 580 nm to 600 nm; and a light condensing unit for collecting the blue, green, and red laser light, and the excitation light, to generate white light.
