Multicolored LED lighting method and apparatus
DCFirst Claim
1. An apparatus, comprising:
- a plurality of first LEDs, each first LED configured to generate first radiation having a first spectrum;
a plurality of second LEDs, each second LED configured to generate second radiation having a second spectrum different than the first spectrum;
a diffuser to blend the first radiation and the second radiation, when generated, so as to provide a uniform color of light having a visible spectrum based on a combination of the first spectrum and the second spectrum; and
at least one controller configured to control the first LEDs and the second LEDs based on a square wave signal applied to each LED, such that all visible light provided by the diffuser is perceived only as one or more colors, and not as alphanumeric characters or graphic images,wherein the apparatus is configured to have a form that resembles a conventional lightbulb.

Abstract
Apparatus and systems including one or more first LEDs, each first LED configured to generate first radiation having a first spectrum, and one or more second LEDs, each second LED configured to generate second radiation having a second spectrum different than the first spectrum. A diffuser is employed to blend the first radiation and the second radiation, when generated, so as to provide a uniform color of light having a visible spectrum based on a combination of the first spectrum and the second spectrum. One or more controllers are configured to control the first LED(s) and the second LED(s) such that visible light provided by the diffuser is perceived as one or more colors. In different aspects, the apparatus/systems may be configured to generate white light and/or multicolor light, may be formed to resemble conventional light bulbs, and may be arranged as a linear chain of nodes.
