    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.

    摘要： This invention relates to luminescent materials for ultraviolet light or visible light excitation comprising copper-alkaline-earth dominated inorganic mixed crystals activated by rare earth elements. The luminescent material is composed of one or more than one compounds of silicate type and/or germinate or germanate-silicate type. Accordingly, the present invention is a very good possibility to substitute earth alkaline ions by copper for a shifting of the emission bands to longer or shorter wavelength, respectively. Luminescent compounds containing Copper with improved luminescent properties and also with improved stability against water, humidity as well as other polar solvents are provided. The present invention is to provide copper containing luminescent compounds, which has high correlated color temperature range from about 2,000K to 8,000K or 10,000K and CRI up to over 90.

    摘要： Disclosed are non stoichiometric Copper Alkaline Earth Silicate phosphors activated by divalent europium for using them as high temperature stable luminescent materials for ultraviolet or daylight excitation. The phosphors are represented as the formula (BauSryCawCux)3−y(Zn,Mg,Mn)zSi1+bO5+2b:Eua. The nonstoichiometric tetragonal silicate is prepared in a high temperature solid state reaction with a surplus of silica in the starting mixture. Furthermore, luminescent tetragonal Copper Alkaline Earth Silicates are provided for LED applications, which have a high color temperature range from about 2,000K to 8,000K or 10,000K showing a CRI with Ra=80˜95, when mixed with other luminescent materials.

    摘要： This invention relates to luminescent materials for ultraviolet light or visible light excitation containing lead and/or copper doped chemical compounds. The luminescent material is composed of one or more than one compounds of aluminate type, silicate type, antimonate type, germanate/or germanate-silicate type, and/or phosphate type. Accordingly, the present invention is a good possibility to substitute earth alkaline ions by lead and copper for a shifting of the emission bands to longer or shorter wave length, respectively. Luminescent compounds containing copper and/or lead with improved luminescent properties and also with improved stability against water, humidity as well as other polar solvents are provided. The present invention is to provide lead and/or copper doped luminescent compounds, which has high color temperature range about 2,000K to 8,000K or 10,000K and CRI over 90.
