LIGHT-EMITTING DIODE MODULES

摘要

Described herein is an LED module (500) comprising a PCBA (200) having an array of LED elements, a secondary lens array (300) and a lens holder (510). The secondary lens array (300) has a peripheral lip (360) and a plurality of boss portions (330a) which are compressed between the lens holder (510) and the PCBA (200) to form water-tight gaskets. The secondary lens array (300) also forms gaskets around wires connecting with terminal blocks on the PCBA (200) and effectively seals with a base plate (100) on which the PCBA (200) is mounted.

主权项

1. A water-tight light-emitting diode module comprising:
a base plate; a printed circuit board mounted on the base plate; a plurality of light-emitting diodes mounted on the printed circuit board; at least two electrical connections mounted on the printed circuit board and electrically connected for supplying power to each of the plurality of light-emitting diodes; a secondary lens array mounted over the plurality of light-emitting diodes on the printed circuit board, the secondary lens array comprising a plurality of secondary lens elements and being configured to provide a cover portion for each of the electrical connections and a sheath portion for each wire being connected to each of the electrical connections; and a lens holder mounted over the secondary lens array, the lens holder comprising a plurality of apertures formed therein for accommodating a respective one of the secondary lens elements and being configured to compress at least one portion of the secondary lens array to form at least one gasket between the lens holder and the base plate to prevent the ingress of water around the printed circuit board.
