Abstract
Ornamental and decorative light display utilizing LEDs constructed of two or more individual diodes. Each diode or portion of a diode is alternately selected and energized at a sufficient frequency that colors can blend to produce another color. The system provides for an extremely large configuration of LEDs to be driven at a low average power and at the same time to allow the user to select individual lights to be constantly illuminated or flash in response on oscillating voltage source or allow multicolored patterns to be generated using bicolor LEDs.
Claims32
A light display comprising:
- electrically conductive primary source connector, a ground connector and a secondary source connector constituting a first electrically conducting string, a number of LEDs, means for connecting the LEDs in parallel across the ground connector and one of the primary and secondary source connectors;
- and
- at least one of said LEDs including a set of bicolor diodes and means for controlling the color of said set by oscillating the current between portions of the diodes at preselected rates;
- and
- said means for controlling the color including oscillating current between portions of said bicolor diodes at such a rate to produce a color different than that of either color of said bicolor diodes.
A light display comprising:
- electrically conductive primary source connector, a ground connector and a secondary source connector constituting a first electrically conducting string, a number of LEDs, means for connecting the LEDs in parallel across the ground connector and one of the primary and secondary source connectors;
- said means for connecting the LEDs in parallel between the primary source and ground connectors and the secondary source and ground connectors includes a member for electrical connection to each of said connectors and having means for connecting LEDs in parallel between the ground connectors and any of the source connectors.
A light display comprising:
- electrically conductive primary source connector, a ground connector and a secondary source connector constituting a first electrically conducting string, a number of LEDs, means for connecting the LEDs in parallel across the ground connector and one of the primary and secondary source connectors wherein at least one of said connectors includes an electronic switching mechanism alternating between on and off positions to connect and disconnect LEDs and energize said LEDs at a predetermined rate;
- means for connecting a second electrically conducting string comprising a second primary source connector, a second secondary source connector and a second ground connector wherein said electronic switching mechanism includes means for oscillating between an on and off position for each of said ground connectors alternating between each string so that the first and second string are not on at the same time;
- said switching mechanism connected to said connectors and having a selection means for selecting a pulse rate for pulsing the LEDs at a rate visible to the human eye;
- and
- means for connecting said LEDs including a member for electrical connection to said ground connector, said primary source connector and said secondary source connector, said LED having first and second connectors cooperating with said member for mechanical engagement of said first and second connectors with said ground connector and any of said primary source connector and said secondary source connector.
A method for producing a yellow light with LED comprising:
- (a) fabricating a bicolor LED in red and green;
- (b) alternately energizing the bicolors at a sufficient rate to produce the color yellow to the human eye.
An apparatus for producing varying colors of light comprising:
- (a) an LED of at least a bicolor configuration in red and green;
- and
- (b) means for alternately energizing said red LED and said green LED to produce a color other than red and green.
