摘要： The invention relates to a wavelength conversion element including: a substrate including a light-reflecting surface and rotatable around an axis of rotation; and a wavelength conversion layer supported by the light-reflecting surface. The wavelength conversion layer has a distribution of reflectance, along a circle centered on the axis of rotation, with respect to excitation light to excite the wavelength conversion layer. An average reflectance of the wavelength conversion layer with respect to the excitation light per the circle varies depending on a radius of the circle.

摘要： A white balance adjustment method and apparatus for a single DLP projector system is disclosed. The projection system includes a solid state light source device, a sync signal generator, and a controller. The light source device generates an output which is a repeating color sequence of at least two primary color lights. The sync signal generator generates a synchronization signal representing a timing of the color sequence of the output light. The controller calculates drive current values corresponding to each of the two primary colors based on a target white balance and measured color properties of the output light, and supplies a modulated drive current to the light source device. The modulated drive current is synchronized to the sync signal and has the calculated drive current values. As a result, a white light having the target white balance is output.
