摘要: Methods for producing wavelength converters are described. The methods include sintering a mixture consisting essentially of first particles and second particles to form a sintered article. In embodiments the first particles consist essentially of particles of β-SiAlON or precursors thereof, and the second particles consist essentially one or more sintering aids or precursors thereof. In embodiments the sintered article has a density that is greater than or equal to about 90% of a theoretical bulk density of the mixture, and is configured to convert primary light incident thereon to secondary light, wherein the secondary light exhibits a peak with a full width half maximum of greater than 0 to about 60 nanometers (nm) within a wavelength range of about 495 nm to about 600 nm.

摘要: A wavelength-conversion plate is described herein. The wavelength conversion plate may include a converter of a first ceramic material and a reflector of a second ceramic material. The first ceramic material converts the primary light emitted by a light source such as a light emitting diode (LED) into a secondary light and the second ceramic material reflects the secondary light emitted by said converter. Preferably, the converter is inlaid into the reflector so that the reflector surrounds an outer edge of the converter. Such a configuration has an advantage of reducing unwanted side emissions from the converter.

摘要: An electrical machine including a casing (1), an oil inlet hole (7), an oil passage (2), oil outlet holes (3), a stator retainer (8), a casing end cover (10), a stator iron core (5), winding coils (6), slot insulations (12) and oil-guides (4). The oil passage (2) is located inside the casing (1) and links with the oil inlet hole (7) of the casing (1) and the oil outlet holes (3) of the stator retainer (8). The oil outlet holes (3) are located above the winding coils (6) and the oil-guides (4) are located between the oil outlet holes (3) and the winding coils (6). Oil entering from the oil inlet hole (7) pours onto the winding coils (6) by the guidance of the oil-guides (4) after flowing through the oil passage (2) and flowing out of the oil outlet holes (3). The winding coils of the electrical machine can be effectively cooled and the electrical machine can achieve higher thermal durability. An oil cooling method for the electrical machine is also provided.
