The present invention provides a specific filtration media which includes a substrate having cellulose fibers, bicomponent fibers, adhesion fibers, binder, and pressure sensitive adhesive. Also contemplated are fire retardant filtration media containing bicomponent fibers and polyester fibers or acrylic fibers, and optionally cellulose fibers. The cellulose fibers of the invention are pretreated with flame retardant, providing a beneficial material for filtration purposes.
摘要:
An apparatus including at least one LED mounted to a printed circuit board, a reflector including at least one heat stake, and a mounting plate comprising at least one aperture for receiving the at least one heat stake. The at least one LED is positioned between the reflector and the mounting plate such that the at least one LED is held in position when the at least one heat stake is received within the at least one aperture.
摘要:
An LED light unit includes a tile, a plurality of discrete LED light sources, and an edge connector. The LED light sources are on and dispersed across a major surface of the tile and are electrically connected to electrical pads along an edge region of the tile. The edge connector includes a plurality of contracts that are connected to a plurality of wires extending away from the edge connector, and is configured to releasably connect to an edge of the tile so that the contacts directly connect to the pads and electrically connect the wires of the edge connector to the LED light sources. An LED lighting assembly includes a plurality of the discrete tiles mounted to a plurality of bars, and a plurality of edge connectors that are each connected to an end one of the tiles along different ones of the bars.
摘要:
A solid state lighting tile includes a substrate and a plurality of lighting element clusters on a surface of the substrate. Respective ones of the plurality of lighting element clusters include first and second mounting positions configured to receive solid state light emitting devices, and at least first and second ones of the solid state lighting element clusters may be electrically connected in series. The tile further includes a plurality of solid state light emitting devices configured to emit a first color light, and respective ones of the solid state light emitting devices may be mounted in respective ones of the plurality of solid state lighting element clusters. One of the first color light emitting devices is mounted in the first mounting position of the first solid state lighting element cluster and a second of the first color light emitting devices is mounted in the second mounting position of the second solid state lighting element cluster.
摘要:
Methods of calibrating a lighting panel including a plurality of segments, each of said segments configured to emit a first color light and a second color light in response to pulse width modulation control signals having respective duty cycles include determining an average segment luminance for the lighting panel, determining a luminance variation of each segment to the average segment luminance, comparing the luminance variation of each segment to a threshold, and adjusting the duty cycle of at least one color of at least one segment to reduce the luminance variation in response to the luminance variation of a segment exceeding the threshold. Calibration systems are also disclosed.
摘要:
Methods and apparatus for modular combinations of structural elements (22) and connectors (30) that are sold as a set of unassembled or partially assembled parts (14), and are then transported and assembled by a consumer (10) having ordinary skill without special tools or expertise.
