    An old CRT television does just that.

    Color mixing just from lights shown-was just the whole question here?
    See my other LED Light question I posted in another discussion page-that tell what other Disco LED light device that I would want (exactly).

    Not sure a cathode-ray tube is classed as a light-emitting diode.... 

    .... Or could it be?

    After all, it is fundamentally a thermionic valve whose anode is a set of phosphor grids (red, green, blue), and any such valve does function as a diode.

    You are very probably looking at one - the  screen you are reading this on.
