Abstract (en)
[origin: WO0143113A1] A display system has a light source which is composed of at least two LED sources having slightly different peak wavelengths of light emission. The separate LED sources are combined into a single beam having increased lumen output with little or no increase in etendue. Such combined sources of different colors (eg., red, green and blue) are useful as the light engine in display systems having a limited etendue, arising for example from the use of small light modulator panels.
