subject: Led Board Give Us A Fascinating [print this page] A modular LED writing board consisting of a circuit board being frangible along a first and second set of intersecting fragmentation lines, the fragmentation lines dividing the circuit board into a plurality of sections. A plurality of LEDs are mounted to the circuit board, at least one LED being mounted to each section, each section having a sub-circuit operatively coupled to the LED, each sub-circuit having a positive and negative lead. The sub-circuits of adjacent sections are operatively coupled together by frangible leads.
LED displays are finding application in a variety of products. Display signs, advertising signs and lighting fixtures are a few examples. A majority of these LED displays use a plurality of LEDs mounted on a circuit board. For a majority of applications, each LED display requires a custom LED writing board. As can be appreciated, the costs of manufacturing custom circuit boards can be quite high. To overcome the high cost of manufacturing custom LED boards, one approach has been to build LED displays from a plurality of modular LED boards. This approach does reduce the cost of manufacturing a LED display; however, this still requires the step of assembling a plurality of smaller LED boards to form a display. In some cases, the cost of assembling a suitable frame to mount the smaller LED boards may be as great as manufacturing a custom board. A modular LED board which is more versatile is therefore required.
In accordance with the present invention, there is provided a modular LED writing board consisting of a circuit board being frangible along a first and second set of intersecting fragmentation lines, the fragmentation lines dividing the circuit board into a plurality of sections. A plurality of LEDs are mounted to the circuit board, at least one LED being mounted to each section, each section having a sub-circuit operatively coupled to the LED, each sub-circuit having a positive and negative lead.
