A process of making a diverging-light fiber optics illumination delivery system includes providing a micro-post comprising a glass-ceramic light-scattering element that includes at least one of a ceramic, a glass ceramic, an immiscible glass, a porous glass, opal glass, amorphous glass, an aerated glass, and a nanostructured glass; and fusion-splicing the glass-ceramic micro-post to the optical fiber by pulling an arc between electrodes across a gap formed by the optical fiber and the glass-ceramic micro-post; maintaining the arc for a time sufficiently long to make facing surfaces of the optical fiber and the micro-post one of malleable and molten; and pushing and thereby fusing together the facing surfaces of the optical fiber and the micro-post. Some embodiments can include fusing the glass-ceramic micro-post to the optical fiber by applying a laser beam to heat up at least one of the facing surfaces of the optical fiber and the glass-ceramic micro-post.

An image projection apparatus includes: a light source (160); an exhaust fan (7) configured to discharge air in the apparatus to outside of the apparatus; and a plurality of wind guiding walls (82a, 82b, 82c, and 82d) extending in a direction perpendicular to an exhaust direction of the exhaust fan (7), and configured to guide air that has cooled the light source (160). The wind guiding walls (82a, 82b, 82c, and 82d) are arranged side by side in a rotation axis direction of the exhaust fan (7). At least a downstream portion of each of the wind guiding walls (82a, 82b, 82c, and 82d) in an air flowing direction after cooling the light source (160), is gradually inclined so as to move away from the exhaust fan (7) in the rotation axis direction of the exhaust fan (7), toward downstream in the air flowing direction.

A light emitting device includes a wavelength conversion element (1), and an excitation light source (40) which radiates excitation light (81) to the wavelength conversion element (1). The wavelength conversion element (1) includes a support member (2) having a supporting surface (2m), and a wavelength conversion member (4) disposed on the supporting surface (2m) so as to be contained within the support member (2) in a top view of the support member (2) from the supporting surface (2m) side. An outer peripheral region (2e) on the support member (2), which is an outer peripheral portion of an arrangement region (2p) including the wavelength conversion member (4) and is exposed from the wavelength conversion member (4), includes a light absorbing portion which can absorb first light having the same wavelength as that of the excitation light (81) or a light scattering portion (2s) which can scatter the first light. The arrangement region (2p) includes a reflective member (reflective film (3)) disposed between the wavelength conversion member (4) and the support member (2), the reflective member being different from the support member (2).
摘要:
The present disclosure provides lamination transfer films and use of the lamination transfer films, particular in the fabrication of architectural glass elements, such as those used in Insulated Glass Units (IGUs). The lamination transfer films may be used to transfer functional layers and structures. The lamination transfer films may include a support film that can be removed during the transfer process, and the transferred materials are primarily inorganic. The resulting transferred structures on glass generally have high photo- and thermal-stability, and therefore can successfully be applied to the glass surfaces that are interior to the cavity within an IGU. The lamination transfer films can also be patterned such that macroscopic patterns of microoptical elements can be applied on a glass surface.

The invention features devices and methods for collecting and measuring light from external light sources. In general, the devices of the invention feature a light diffusing element, e.g., as a component of a light collector, connected by a light conducting conduit, e.g., a fiber optic cable, to a light measuring device, e.g., a spectrometer. This light diffusing element allows, e.g., for substantially uniform light diffusion across its surface and thus accurate measurements, while permitting the total footprint of the device to remain relatively small and portable. This light diffusing element also allows flexibility in scaling of the device to permit use in a wide range of applications.
