Abstract
A solid state multi-spectral light source for a multi-spectral light source system includes an array of LED groups, wherein each LED group may include red, green, and blue LEDs. The LEDs produce color light bars by activating the appropriate color LEDs. The color light bars can be flashed or scrolled to integrate a color display.
Claims15
A solid state multi-spectral light source comprising:
- a plurality of light-emitting diodes, wherein at least two of the light-emitting diodes produce two different colors.
A multi-spectral light source system comprising:
- a light valve;
- and
- a solid state multi-spectral light source that scrolls or flashes different colored light bars onto the light valve to produce a color image, the light source including a plurality of light-emitting diodes, wherein at least two of the light-emitting diodes produce two different colors.
A method of producing multi-spectral light, the method comprising:
- providing plurality of light-emitting diodes;
- producing at least two different colors from at least two of the light-emitting diodes.
