Abstract:
1. An expandable LED module for arbitrary display assembly, comprising: a housing; a print circuit board; at least one light emitting diode being disposed on said print circuit board; said print circuit board has at least one positive polarity pad, one negative polarity pad, and circuit traces for coupling to said at least one light emitting diode; a first connecting device being disposed on one side of said print circuit board and being coupled to said at least one light emitting diode; the first connecting device has a positive polarity contact and a negative polarity contact connecting with said positive polarity pad and the negative polarity pad respectively, and the first connecting device coupling to said at least one light emitting diode; a second connecting device being disposed on another side of said print circuit board and being coupled to said at least one light emitting diode; said second connecting device comprises a positive polarity contact and a negative polarity contact connecting respectively with said positive polarity pad and negative polarity pad, and the second connecting device coupling to said at least one light emitting diode; said second connecting device interconnecting with said first connecting device, wherein the interconnecting of said first connecting device and second connecting device expanding said expandable LED module; the expandable LED module displays figures, words, numbers, or symbols; wherein said first connecting device is a gold finger or pin header; wherein said second connecting device comprises a slot; the positive polarity contact and the negative polarity contact of the second connecting device both extending outside of said second connecting device; and a housing having a room open in two sides to provide a placement for said print circuit board; a plurality of through holes on a surface of said housing for said at least one light emitting diode to be exposed.
