Abstract
High lumen output and brightness illumination modules using an excitation light source and wavelength conversion part with multi-channel heat dissipation are disclosed. The exciting light source is a light emitting diode or a laser diode emitting in the UV and/or blue region. The luminescent material in the wavelength conversion part absorbs the excitation light and emit longer wavelength light. The enhancement approaches for brightness and polarization is disclosed.
