摘要： An LED unit includes an LED having an optical axis and a lens mounted on the LED. The lens includes an incidence surface, an emission surface, and a light-reflecting face between the incidence surface and the emission surface. The light-reflecting face has a diameter gradually increasing from a bottom towards a top of the lens. The incidence surface includes a first incidence surface and a second incidence surface extending downwardly from a circumference of the first incidence surface and protruding inwardly towards the LED. Light emitted from the LED with a large angle is refracted by the second incidence surface into substantially parallel beams in one side of a cross-section of the lens through the optical axis of the LED, and the parallel beams are sequentially reflected by the light-reflecting face and refracted by the emission surface out of the lens in substantially parallel beams.

摘要： The present invention relates to alkaline earth metal silicate luminophores having improved long-term stability and to a corresponding method for improving the long-term stability of alkaline earth metal silicate luminophores. The luminophore according to the invention is a luminophore comprising a base lattice according to the general chemical formula EAxSiyOz, where x, y, z>0. The component EA is formed by one or more alkaline earth metals. An activator, for example Eu2′ or Mn2′, is doped into the base lattice. The luminophore has the fundamental property to absorb radiation in a first wavelength range and emit radiation in a second wavelength range that is different from the first wavelength range. The luminophore is designed in the form of crystals. According to the invention, the surfaces of the crystals of the luminophore are chemically modified such that at least portions of the surfaces thereof are formed by a chemical compound of the general formula EauZ2. The component Z is formed by anions, which can be chemically combined with the EA cations of the luminophore. The variable u is equal to an ion charge of the anions Z. The chemical modification is therefore not a coating.

摘要： An amplifier circuit includes an input terminal and an output terminal. A current sinking transistor includes a first conduction terminal coupled to the output terminal and a second conduction terminal coupled to a reference supply node. A voltage sensing circuit has a first input coupled to the input terminal and a second input coupled to the output terminal. An output of the voltage sensing circuit is coupled to the control terminal of the current sinking transistor. The voltage sensing circuit functions to sense a rise in the voltage at the output terminal which exceeds the voltage at the input terminal, and respond thereto by activating the current sinking transistor.

摘要： The invention relates to a method of manufacturing a rare-earth doped alkaline-earth silicon nitride phosphor of a stoichiometric composition. Said method comprising the step of selecting one or more compounds each comprising at least one element of the group comprising the rare-earth elements (RE), the alkaline-earth elements (AE), silicon (Si) and nitrogen (N) and together comprising the necessary elements to form the rare-earth doped alkaline-earth silicon nitride phosphor (AE2Si5N8:RE). The method further comprises the step of bringing the compounds at an elevated temperature in reaction for forming the rare-earth doped alkaline-earth silicon nitride phosphor (AE2Si5N8:RE). In such a method normally a small amount of oxygen, whether intentionally or not-intentionally added, will be incorporated in the rare-earth doped alkaline-earth silicon nitride phosphor (AE2Si5N8:RE). According to the invention the creation of defects by formation of a non-stoichiometric oxygen containing phosphor is at least partly prevented by partly substituting for the ions (AE, Si, N) of the alkaline-earth silicon nitride phosphor (AE2Si5N8:RE) suitable further elements of the periodic system by which vacancies are created, filled or annihilated resulting in the formation of a modified alkaline-earth silicon nitride phosphor (AE2Si5N8:RE) having a stoichiometric composition. In this way a modified phosphor is obtained having excellent and stable optical properties. The invention further relates to a modified phosphor obtainable by the above-mentioned method and a radiation converting device comprising such a phosphor.
