Conventionally-shaped light bulbs employing white LEDs

An LED-based light bulb, comprising:

• at least one first white LED to generate first radiation having a first spectrum;
• at least one second LED to generate second radiation having a second spectrum different than the first spectrum;
• at least one power connection having a form to engage mechanically and electrically with one of a conventional Edison-mount screw-type light bulb socket, a conventional fluorescent tube coupler arrangement, and a conventional halogen MR-16 socket arrangement;
• and
• at least one voltage transformation device, coupled to the at least one first white LED, the at least one second LED, and the at least one power connection, to electrically transform a first voltage applied to the at least one power connection, via the one of the conventional Edison-mount screw-type light bulb socket, the conventional fluorescent tube coupler arrangement, and the conventional halogen MR-16 socket arrangement, to a second voltage that provides operating power to the at least one first white LED and the at least one second LED,
• wherein the LED-based light bulb substantially corresponds in shape to a corresponding one of a conventional Edison-mount screw-type light bulb, a conventional fluorescent tube, and a conventional halogen MR-16 light bulb based on the form of the at least one power connection.
