LED is one of the green light sources in the 21st century
and it has broad prospects in the illumination. In recent years
there have been more and more LED lamps
and designing appropriate LED lamps become very important. The power of a single LED is very small
but lighting requires the uniform flux and illuminance in a certain region
so it is necessary to use LED arrays for increasing the brightness and luminous area
improving the uniformity of illuminance. This paper calculated illuminance of the LED arrays at first
and then according to known functions
the LED arrays were simulated and analyzed. The distribution characteristics of the different LED arrays were obtained by comparing the characteristics of two kinds of LED arrays. Finally
the law of arrays suiting lamps was shown
which will be able to provide the accurate reference for designing LED lamps.
