    摘要: Disclosed herein is a light emitting device including one or more light emitting diodes to primarily emit light having different wavelengths in the wavelength range of ultraviolet rays and/or blue light, and a wavelength-conversion means to convert the primary light into secondary light in the visible light wavelength range. The light emitting device of the current invention has a high color temperature of 2000 to 8000 K or 10000 K and a high color rendering index of 90 or more, thus easily realizing desired emission on the color coordinate system. Therefore, the lighting emitting device is applicable to mobile phones, notebook computers, and keypads or backlight units for various electronic products, and, in particular, automobiles and exterior and interior lighting fixtures.

    摘要: A light emitting device is disclosed. The light emitting device may include a light emitting diode (LED) for emitting light and a phosphor adjacent to the LED. The phosphor may be excitable by light emitted by the LED and may include a first compound having a host lattice comprising first ions and oxygen. In one embodiment, the host lattice may include silicon, the copper ions may be divalent copper ions and the first compound may have an Olivin crystal structure, a β-K2SO4 crystal structure, a trigonal Glaserite (K3Na(SO4)2) or monoclinic Merwinite crystal structure, a tetragonal Ackermanite crystal structure, a tetragonal crystal structure or an orthorhombic crystal structure. In another embodiment, the copper ions do not act as luminescent ions upon excitation with the light emitted by the LED.

    摘要: Disclosed herein is a light emitting device including at least three light emitting diodes having different peak emission wavelengths to primarily emit light in a blue, green or red wavelength range, and a wavelength-conversion means to convert primary light into secondary light in a visible light wavelength range. The light emitting device of the current invention has a high color temperature of 2,000 to 8,000 K or 10,000 K and a high color rendering index of 90 or more, and emits yellow-green light or orange light having a wide emission wavelength range. Since the light emitting device having high color temperature and excellent color rendering properties can easily realize desired emission on the color coordinate system, it is applicable to mobile phones, notebook computers, and keypads or backlight units for various electronic products, and in particular, automobiles and exterior and interior lighting fixtures.
