Abstract
A vented LED display is described including an LED display panel having a plurality of LEDs disposed thereon and defining a plurality of vent slots between the plurality of LEDs, each of the plurality of vent slots having a vent height. The vented LED display also includes a unitary injection-molded vent having a plurality of louvers and coupled to the LED display panel such that each louver corresponds to at least one vent slot and includes a louver length extending downwardly to at least 75% of the vent height of the corresponding vent slot.
Claims20
A vented LED display comprising:
- an LED display panel having a plurality of LEDs disposed thereon and defining a plurality of vent slots between the plurality of LEDs, each of the plurality of vent slots having a vent height;
- and
- a unitary injection-molded vent having a plurality of louvers and coupled to the LED display panel such that each louver corresponds to at least one vent slot and includes a louver length extending downwardly to at least 75% of the vent height of the corresponding at least one vent slot.
A vented LED display comprising:
- a monolithic LED display panel having LEDs disposed thereon in a matrix arrangement of rows and columns separated by one or more vent slots between the rows;
- and
- a vent formed as a unitary structure, coupled to the monolithic LED display panel, and having a plurality of louvers, each of the plurality of louvers corresponding to at least one of the one or more vent slots so as to define a fluid pathway shaped and configured to allow fluid to flow through the vented LED display from a front face thereof through a rear face thereof.
A method of manufacturing a vented LED display, the method comprising steps of:
- providing a first three-dimensional pattern formed on a molding surface of a first mold;
- injecting a polymeric fluid material into the first mold and curing the polymeric fluid material in the first mold so as to form a first injection-molded member including an LED display panel surface defining one or more vent slots, each vent slot including a vent height;
- providing a second three-dimensional pattern formed on a molding surface of a second mold;
- and
- injecting a polymeric fluid material into the second mold and curing the polymeric fluid material in the second mold so as to form a second injection-molded member including a plurality of louver surfaces arranged so that each louver surface includes a louver length that extends downwardly to at least 75% of the vent height.
