1. A method for conveying information, comprising:
- A) receiving, from a data base, a network, the World Wide Web, or a software program, at least one information signal representing scalar or numeric information that is not associated with color;
B) converting the at least one information signal representing the scalar or numeric information into at least one illumination control signal representing at least color information; and
C) controlling at least a color of illumination generated by at least one LED-based light source in response to the at least one illumination control signal so as to convey the scalar or numeric information via at least the color of the generated illumination.

Abstract
Methods and apparatus for conveying information. One or more information signals representing scalar or numeric information that is not associated with color is/are received from a data base, a network, the World Wide Web, or a software program. The information signal(s) is/are converted into one or more illumination control signals representing at least color information, and a color of illumination generated by one or more LED-based light sources is controlled in response to the illumination control signal(s) so as to convey the scalar or numeric information via at least the color of the generated illumination.

18. An apparatus, comprising:
-
at least one LED-based light source; and at least one controller coupled to the at least one LED-based light source, the at least one controller configured to; receive, from a data base, a network, the World Wide Web, or a software program, at least one information signal representing scalar or numeric information that is not associated with color; convert the at least one information signal representing the scalar or numeric information into at least one illumination control signal representing at least color information; and control at least a color of illumination generated by the at least one LED-based light source in response to the at least one illumination control signal, so as to convey the scalar or numeric information via at least the color of the generated illumination. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
