- white LEDs have a narrow white area distributed in color coordinates when spectroscopically analyzed, and thus there is room for improvement of optical characteristics such as color stability and color rendering.
- the present invention is to provide a white LED having excellent color rendering index and high color stability by using blue light and red, green and blue green phosphors.
- LED Chip that emits blue light and absorbs blue light to emit red light, green light emitting phosphor to emit green light, blue light emitting phosphor to emit blue green light
- a mixture of three kinds in a predetermined blending ratio provides a method of obtaining color stability and high color rendering index of white light emission.
- three kinds of phosphors for converting wavelengths are added to the blue, green, and blue-green regions excited by light emission from the semiconductor light emitting device, and are characterized by high color stability and color rendering index when the object is irradiated.
- the LED is characterized in that the form selected from the group consisting of SMD form, LAMP form and COB form.
- White LED according to the present invention can obtain an excellent color rendering index of Ra 98 or more, Ri 95 or more.
- 1 is an example of color rendering index evaluation analysis according to an embodiment of the present invention using a blue light excited high color rendering SMD 5mm element 3 chip type
- 3 is an example of the color rendering index evaluation analysis according to an embodiment of the present invention using a blue light excited high color rendering COB 26 Watt class 144 chip type
- the present invention mixes three kinds of LED elements emitting blue light, red emitting phosphors absorbing blue light to emit red light, green emitting phosphors emitting green light, and blue green emitting phosphors emitting blue green light in a predetermined blending ratio.
- the present invention relates to a lighting device that realizes a method of improving the color rendering property when irradiated to an object.
