摘要： A Far UV C excimer bulb assembly including an excimer bulb, and a curved filter external to and separated from the excimer bulb. The curved filter being hafnium based and including an arc. The excimer bulb emits radiation in a plurality of wavelengths substantially comprising Far UV C. The curved filter having a cut-off wavelength of 234 nm and adapted to block substantially all wavelengths of UV C radiation longer than 234 nm. The excimer bulb is positioned at least partially and centered within the arc so that the majority of the Far UV C wavelengths of radiation pass perpendicularly through the curved filter. The assembly may further include a mirror which may also be curved, and plated onto the exterior surface of the excimer bulb.

摘要： A plasma cell for use in a laser-sustained plasma light source includes a plasma bulb configured to contain a gas suitable for generating a plasma, the plasma bulb being transparent to light from a pump laser, wherein the plasma bulb is transparent to at least a portion of a collectable spectral region of illumination emitted by the plasma. The plasma bulb of the plasma cell is configured to filter short wavelength radiation, such as VUV radiation, emitted by the plasma sustained within the bulb in order to keep the short wavelength radiation from impinging on the interior surface of the bulb.

摘要： A lamp has a light emitting element within a sealed transparent vessel. The vessel comprises a cylindrical section with a longitudinal axis L in parallel to a longitudinal axis F of the light emitting element. In order to provide a lamp suited for compact reflectors, a heat shielding element is arranged to shield at least infrared light. The heat shielding element is arranged in parallel to the longitudinal axis F of the light emitting element and has an axial extension of at least 80% of the light emitting element. The heat shielding element is arranged to shield infrared light emitted into directions perpendicular to the longitudinal axis F covering a circumferential extension of 20°-120° measured in cross section.

摘要： An ultraviolet light emitting device comprises: a first substrate having a main surface; a second substrate facing the main surface of the first substrate; a gas in a space between the first substrate and the second substrate; electrodes directly or indirectly on the main surface of the first substrate; a dielectric layer that is located directly or indirectly on the main surface of the first substrate and covers the electrodes; and a first light-emitting layer. The first light-emitting layer is located directly or indirectly on the dielectric layer and emits ultraviolet light in the gas due to electrical discharge between the electrodes. The first light-emitting layer is thicker in first regions on the dielectric layer than in second regions. The second regions include at least part of regions directly above the electrodes.

摘要： A light-extraction apparatus for an optical-film lighting set having a visible-light coating include a transparent sealed body, a wide AOR (0 degree to 90 degrees) optical film for reflecting ultraviolet lights and a visible light layer. The transparent sealed body is formed as a hollow shell body to accommodate an ultraviolet light source. A supporting member coated with the optical film and the visible light layer is constructed to a wall of the shell body or inside the shell body. The visible light layer is consisted of monolayered fluorescent or phosphorescent particles, and the particles are evenly distributed to coat on the interior wall of the shell body or the supporting member inside the shell body in a sparse scattering manner. A fixed area ratio of the coverage of the particles to that of the inter-particle spacing is then provided to the visible light layer for obtaining a higher illumination performance.
