  • Method and apparatus for producing a uniform irradiance distribution from an array of light emitting diodes
    Patent number: 8430526
    Abstract: An apparatus and method for producing a spatially uniform irradiance in an image plane are provided. The apparatus includes an array of light emitting diodes (LEDs) which generate light (i.e., an image). The apparatus combines the outputs of an array of the LEDs in such a way as to produce a spatially uniform irradiance in an image plane some distance away. The apparatus includes an array of lenslets to form images of the emitting areas of the individual LEDs. The lenslets have a magnification, size and spacing such that the images produced by the respective LEDs are adjacent to one another and not overlapping. The irradiance distribution in the image plane is equivalent to an image of an LED whose emitting area is equal to the total area of the LED array, and whose total power is equal to the total power of the LEDs in the LED array.
