Abstract
The invention provides a complementary color light source device, which comprises a light emitting unit, a mask and a complementary color film layer. The mask comprises a hollow portion, and the hollow portion contains the light emitting unit. The complementary color film layer is uniformly attached to a side of the mask, and a part of the first wavelength light generated by the light emitting unit passes through the complementary color film layer to generate a second wavelength light. The second wavelength light and the first wavelength light generated by the light emitting unit are color mixed to generate white light. The invention provides the first wavelength light generated by the light emitting unit to transform to the second wavelength light with complementary color, and color mixing both lights to achieve a light source device with low cost, high light emission efficiency, high service life and high color rendering index.
