Latest Patents
One of her latest patents is an "Illuminant system using high color temperature light emitting diode and manufacture method thereof." This invention provides a LED illuminant system that includes a mix of white light illuminants and at least one green light illuminant. The light power ratio of the green light illuminant to the white light illuminants is between ⅓ to 1/20. By mixing these illuminants, the color temperature of the entire system is enhanced. The manufacturing method involves obtaining a transmission spectrum of the white light illuminants and determining the supplemental amount of green light needed.
Another significant patent is the "Backlight module and method of manufacture using complementary light sources having the same color." This backlight module consists of an optical film set and multiple light source sets. The first light source generates a first chromaticity light, while the second light source produces a second chromaticity light. These lights mix in the space between the light source sets and the optical film set, entering the optical film set with their unique spectra.
