Abstract
LEDs of a light matrix display are mounted between two metal frames. Each frame has air ducts to circulate air around the LEDs, thereby removing the heat generated in the LEDs and allowing higher intensity light to be emitted.
Claims15
A light emitting diode (LED) matrix display panel, comprising:
- an array of LEDs each having a first electrode and a second electrode;
- a first metal frame for bonding the first electrode of said LED, having a plurality of first large air ducts,
- a second metal frame for mounting said LEDs and bonding the second electrode of said LED, having a plurality of second air ducts each corresponding to said first large air ducts;
- spacers to separate said first metal frame and said second metal frame, and
- circulating air in said first larger air ducts and second larger air ducts for cooling the said LEDs.
