一种发光装置及具有该发光装置的发光器件
摘要：
本发明提供一种发光装置及具有该发光装置的发光器件，该发光装置至少包括两种类型的发光二极管芯片以及包覆在该发光二极管芯片表面的荧光粉层，其中第一种芯片表面涂敷的荧光粉为一种或多种红色荧光粉，第二种芯片表面涂敷的荧光粉为一种或多种黄色荧光粉和/或绿色荧光粉。本发明的发光装置包括两种类型的发光二极管芯片，红色荧光粉与黄色荧光粉和/绿色荧光粉分别涂覆在不同的芯片上，黄色荧光粉和/或绿色荧光粉受激发后发射出的光没有被红色荧光粉所吸收，从而提高了黄色和/或绿色荧光粉的发光效率，进而提高了整个装置的发光效率。
摘要（英）：

The invention provides a light emitting component and a light emitting device with the light emitting component. The light emitting component at least comprises light-emitting diode chips of two kinds and fluorescent powder layers which cover the surfaces of the light-emitting diode chips. Fluorescent powder sprayed on the surface of the first kind of chip is one or more kinds of red fluorescent powder and fluorescent powder sprayed on the surface of the second kind of chip is one or more kinds of yellow fluorescent powder and/or green fluorescent powder. The light emitting component comprises the light-emitting diode chips of two kinds. The red fluorescent powder and the yellow fluorescent powder and/or the green fluorescent powder are sprayed on different chips respectively. The light emitted by the yellow fluorescent powder and/or the green fluorescent powder which are/is stimulated is not absorbed by the red fluorescent powder, so that the light emitting efficiency of the yellow fluorescent powder and/or the green fluorescent powder is improved and the light emitting efficiency of the whole component is improved.
