The specification and drawings present a new apparatus such as a lighting apparatus, the apparatus comprising at least one LED (or OLED) module, configured to generate a visible light such as white light, and at least one component such as optical component comprising a compound consisting essentially of the elements neodymium (Nd) and fluorine (F), and optionally including one or more other elements. The lighting apparatus is configured to provide a desired light spectrum by filtering the generated visible light using the compound. The at least one component can comprise a NdFOcompound with values of x and y determining a content ratio F/O, which may be adjusted during manufacturing of the NdFOcompound to provide desired output light parameters of the apparatus including at least a desired output light spectrum realized by filtering the generated visible light using the NdFOcompound.

A lamp assembly includes a base, a hermetically sealed outer jacket mounted on the base, and a driver circuit disposed within the hermetically sealed outer jacket and electrically coupled to the base. The lamp assembly may also include a safety circuit configured to interrupt electrical power to the lamp assembly if the hermetically sealed outer jacket is compromised.

The present disclosure provides a lamp assembly (), comprising a base (), an outer jacket () mounted to the base (), a first reflective substrate () positioned within the outer jacket (), and a first solid-state light source () disposed proximate the first reflective substrate (). The outer jacket () may be glass. The outer jacket () may hermetically seal the first solid-state light source ().

LED lamp with internal mirror

An apparatus includes an LED light source positioned within an envelope, a porous fluid transporting material coating the envelope, providing a path between the LED light source and the envelope, and a cooling medium conducted through the fluid transporting material toward the LED light source in a liquid phase and conducted from the LED light source to the envelope in a vapor phase for removing heat from the LED light source.

Phosphor-containing coating compositions and methods capable of changing the lumen maintenance characteristics of phosphor-containing coatings and fluorescent lamps that utilize such coatings. Lumen maintenance of a fluorescent lamp can be modified by forming a phosphor-containing coating to contain at least a first phosphor that depreciates during operation of the fluorescent lamp, and forming the phosphor-containing coating to further contain an additive composition in a sufficient amount and sufficiently uniformly distributed in the phosphor-containing coating to inhibit depreciation of the first phosphor during operation of the fluorescent lamp.

Compositions and methods for modifying lumen maintenance characteristics of phosphor-containing coatings

A method is provided for removing organic impurities in the recycling of phosphors from fluorescent lamps. Particles created from the lamps are washed with a bleaching agent to decompose the organic materials. The organic materials are thereby solubilized and can be removed. The phosphors can then be recovered and reused to manufacture fluorescent lamps.

Chemical bleaching for improved performance of recycled lamp phosphors

A method is provided for recovering phosphor materials from fluorescent lamps. Particles created from the lamps are washed by mixing with water and carboxylic (e.g., acetic) acid while controlling the temperature. The carboxylic acid reacts with basing cement, particularly calcium carbonate, without significant reaction with the phosphors. After this reaction, the phosphors can be removed and e.g., reused in the production of fluorescent lamps.

Fluorescent lamp phosphor recycling

A fluorescent lamp is provided including a phosphor blend comprising less than about 10% by weight rare earth phosphor, based on the total weight of the phosphor composition. This phosphor blend, when coated on a lamp, provides a lamp that exhibits high color rendering index (CRI), of at least 87, while simultaneously achieving low CCT, of less than about 4500K, i.e. of between about 3000K and 4500K. The phosphor system provided includes a non-rare earth strontium red broad band phosphor, a non-rare earth blue broad band halophosphor, and a rare earth-doped green-blue emitting phosphor, more specifically, a combination of SAR and blue-halo non-rare earth phosphors, and less than 20 wt % BAMn phosphor, based on the total weight of the phosphor system.

Strontium phosphor blends having high CRI

A fluorescent lamp includes a phosphor composition comprising: YO:Eu(YEO); at least one of LaPO:Ce, Tb(LAP), MgAlO:Ce, Tb(CAT) or GdMgBO:Ce, Tb(CBT); a special BAMn phosphor, (Ba,Sr,Ca)(MgMn)AlO:Eu, with a specific amount of Mn (x) as disclosed herein, and optionally halophosphor, with the proviso that there is no BaMgAlO:Eu(BAM).

Mercury vapor discharge fluorescent lamps are provided. The lamp can include a lamp envelope enclosing a discharge space and having an inner surface. First and second electrodes can be positioned on the lamp, such as on opposite ends of the lamp envelope. An ionizable medium that includes mercury and an inert gas can be within said lamp envelope. A phosphor layer can be on the inner surface of the lamp envelope. The phosphor layer generally includes a phosphor blend of a calcium halophosphor, a blue phosphor having an emission peak at about 440 nm to about 490 nm, a blue-green phosphor having an emission peak at about 475 nm to about 530 nm, and a red phosphor having an emission peak at about 600 nm to about 650 nm.

Phosphor system for improved efficacy lighting sources

Improved recyclability of phosphors in fluorescent lamps is provided. A fluorescent lamp is constructed with phosphor particles having a specific surface area less than a certain predetermined value. During recycling, these phosphor particles are more readily separated from the basing cement used in such fluorescent lamp. A method is also provided by which such phosphors are more readily separated from the basing cement.

A method for providing a boron-lined neutron detector. The method includes providing a boron-containing material and providing water. The method includes mixing the boron-containing material into the water to create a water-based liquid mixture and providing a substrate of a cathode of the neutron detector. The method includes applying the water-based liquid mixture to the substrate of the cathode and removing water from the water-based liquid applied to the substrate to leave a boron-containing layer upon the substrate that is sensitive to neutron impingement. The step of providing a boron-containing material may be to provide the material to include B-10.

A neutron detector includes an exterior shell bounding an interior volume. The neutron detector includes at least a wall portion serving as a cathode. In one example the wall portion has microfeatures. The neutron detector includes a central structure located within the interior volume and serving as an anode. The neutron detector includes a boron coating on the wall portion. In on example, the boron coating is applied by an electrostatic spray process. In one example, the boron coating conforms to the microfeatures on the wall portion. In one example, the wall portion has a thickness of between 2 to 5 microns. The neutron detector includes an electrical connector operatively connected to the central structure for transmission of a signal collected by the central structure. An associated method provides for depositing the boron coating.

A low-pressure discharge lamp includes, in an exemplary embodiment, a light-transmissive envelope, a fill-gas composition capable of sustaining a discharge sealed inside the light-transmissive envelope, and a phosphor composition at least partially disposed on an interior surface of the light-transmissive envelope. The phosphor composition is disposed on an interior surface of the light-transmissive envelope in a plurality of layers that include at least a basecoat phosphor layer and a topcoat phosphor layer. The basecoat phosphor layer includes at least one halophosphor and the topcoat phosphor layer includes a blend of at least two rare earth phosphors. The basecoat phosphor layer has a greater Color Rendering Index (CRI) value than the topcoat phosphor layer.
