Abstract
The present invention of a purplish pink light emitting diode irradiates a purple light with a wavelength ranging from 405 to 430 nm of a LED chip of a light emitting diode onto a red fluorescent powder coated on the surface thereon such that the purple light excites the fluorescent powder to produce a red light with a wavelength about 650 nm. The mixture of the excited red light and the original purple light from the purple light emitting diode produces a purplish pink or pinkish red light emitting diode in a new color tone with extensive application. To use the neoteric and unique color (similar to the color of a Hello Kitty) as a backlight or for displaying or illumination on electronic merchandises, such as mobile phones, attracts the consumers of the young generation.
Claims4
A purplish pink light emitting diode comprising:
- a LED chip of a purple light emitting diode with a light emission wavelength ranging from 405 to 430 nm;
- and
- an excited red fluorescent powder with components of 6(MgO).As2O5:
- Mn or 3.5(MgO).0.5(MgF2).GeO2:
- Mn applied to the LED chip;
- wherein
- the light emitted from the LED chip of the purple light emitting diode with a wavelength ranging from 405 to 430 nm excites the red fluorescent powder coated thereon to produce a red color light with a wavelength about 650 nm;
- and
- mixing the red and the purple color lights produces the purplish pink light emitting diode.
