摘要： A semiconductor light emitting element emits ultraviolet light or blue light that impinges upon a light emitting cover portion including a blue phosphor, a green phosphor, a red phosphor and a deep red phosphor to emit white light by mixing the light emission colors from the phosphors. The deep red phosphor has a main emission peak in a longer wavelength region than a main emission peak of the red phosphor. The red phosphor includes at least one component selected from: a europium-activated SiAlON phosphor and a europium-activated CASN phosphor each having a predetermined composition. The deep red phosphor includes a manganese-activated magnesium florogermanate phosphor having a predetermined composition. The white light emitting lamp is excellent in both high luminance and high color rendering properties.

摘要： The present invention provides a white LED comprising: an ultraviolet emitting diode or a purple light emitting diode; and phosphors for emitting at least three visible lights including blue light, green light and red light; wherein an emission spectrum of the white LED has: a first luminescence peak in a blue light region having a wavelength of 440-460 nm; a second luminescence peak in a green light region having a wavelength of 510-530 nm; and a third luminescence peak in a red light region having a wavelength of 620-640 nm. Further, it is preferable that a half bandwidth of each of the luminescence peaks is 50 nm or less. As a result, there can be provided a white LED, backlight and liquid crystal display using the white LED exhibiting a high luminance and an excellent color reproducing property.

摘要： A socket tool for alternative use in combination with a screw driver or a conventional wrench. A socket body is formed so as to fit externally over a driver bit and is movable axially therealong and is detachable therefrom but is non-rotatable relative to the driver bit over its length. Socket portions are provided on opposite end portions of the socket body, with internal dimensions different from one another. Outer peripheries of the socket portions at both ends of the socket body are formed into regular polygonal shapes in cross section and serve as external drive engaging faces, to be engaged externally by the wrench. The outer peripheries of both the socket portions have external diameters different from one another. The socket tool is held alternatively on either the driver bit or the wrench, with one of the socket portions engaging the driver bit or wrench and the other socket portion projecting longitudinally away therefrom.
