Abstract

The light emitting diode assembly for an illuminated sign is disclosed having an enhanced waterproofs function and an enhanced durability. The light emitting diode assembly includes a case being open upwards, in which a connecting recess is formed on upper portions of both sides of the case. A printed circuit board is installed in the case and being mounted on upper sides of a plurality of light emitting diodes. The hollow cap is coupled in the connecting recess of the case, in which a plurality of wires passes through the cap. A synthetic resin material for covering the printed circuit board, the cap and the light emitting diode, is filled in the case. In this structure, the light emitting diode assembly can prevent the printed circuit board, transformer and the light emitting diode from being damaged by using an epoxy resin.

Claims (6)

1. A light emitting diode assembly for an illuminated sign, the light emitting diode assembly comprising:

a case being open upwards, in which a connecting recess is formed on upper portions of both sides of the case;

a printed circuit board being installed in the case and being mounted on upper sides of a plurality of light emitting diodes;

a hollow cap being coupled in the connecting recess of the case, in which a plurality of wires pass through the cap, wherein the cap includes a guiding pipe, in which a coupling groove is formed along a lower edge of the cap so that the cap is inserted into the connecting recess of the case, in which the guiding pipe outwardly protrudes from one side of the guiding pipe; and

a synthetic resin material for covering the printed circuit board, the cap and the light emitting diode, the synthetic resin material being filled in the case.

2. The light emitting diode assembly for an illuminated sign as claimed in claim 1 , wherein the synthetic resin material comprises an epoxy resin.
