发明名称 LED発光装置
摘要 <P>PROBLEM TO BE SOLVED: To provide an LED light emitting device having little sense of incongruity even if it is replaced by an incandescent lamp, since shifting of an illumination region is hardly recognized by a user even if a light emitting amount and a light emitting color temperature are lowered as a whole of the device. <P>SOLUTION: The LED light emitting device 10 is composed of an LED unit 12 in which a low color temperature region 26 by a low color temperature LED 20 and a high color temperature region 28 by a high color temperature LED 22 are formed, a reflector 14 of a bowl shape with a reflection face 30 formed on an inner face, and a lens 16. One out of the low color temperature region 26 and the high color temperature region 28 is formed on an outer circumference of the other color temperature region, and the light Lb emitted from the color temperature region 26 in an inner side by using the lens 16 and a part of the light Lc emitted from the color temperature region 28 on an outer circumferential side are converged to an illumination region S, and the remaining light La emitted from the color temperature region 28 of the outer circumferential side by the reflection face 30 is converged to the illumination region S. <P>COPYRIGHT: (C)2013,JPO&INPIT
