Abstract
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.
Claims28
A lens module designed to be mounted over a plurality of light-emitting diodes and electrical connections mounted on a first side of a printed circuit board, said electrical connections being electrically connected for supplying power to the plurality of light-emitting diodes;
- said lens module comprising:
- a secondary lens array mountable over the plurality of light-emitting diodes on the printed circuit board, the secondary lens array molded as a single component comprising a body portion integrally formed with at least one secondary lens element and integrally formed with a cover portion for the electrical connections;
- and
- a lens holder mounted over the secondary lens array, the lens holder comprising a frame comprising one or more apertures, said frame being configured for accommodating the at least one secondary lens element in said one or more apertures, and said frame being configured for accommodating the cover portion, and said frame being configured to compress at least a portion of the secondary lens array to form at least one gasket at a periphery of the lens holder.
A lens module designed to be mounted over a plurality of light-emitting diodes mounted on a first side of a printed circuit board, with wires for supplying power to the plurality of light-emitting diodes, said lens module comprising:
- a secondary lens array molded as a single component and mounted over the plurality of light-emitting diodes on the printed circuit board, the secondary lens array comprising a body portion integrally formed with at least one secondary lens element and integrally formed with at least one sheath portion for the wires;
- and
- a lens holder mounted over the secondary lens array, the lens holder comprising a frame comprising one or more apertures, said frame being configured for accommodating the at least one secondary lens element in said one or more apertures, and said frame being configured for accommodating the at least one sheath portion and being configured to compress at least a portion of the secondary lens array to form at least one gasket at a periphery of the lens holder.
A lens module designed to be mounted over a plurality of light-emitting diodes mounted on a first side of a printed circuit board;
- said lens module comprising:
- a secondary lens array mounted over the plurality of light-emitting diodes on the printed circuit board, the secondary lens array being molded in one piece and being integrally formed of a single material with a plurality of secondary lens elements aligned with the plurality of light-emitting diodes;
- and
- a lens holder mounted over the secondary lens array, the lens holder comprising a frame comprising one or more apertures, said frame being configured for accommodating the plurality of secondary lens elements in said one or more apertures, and said frame being configured to compress at least a portion of the secondary lens array to form at least one gasket at a periphery of the lens holder.
A lens module designed to be mounted over a plurality of light-emitting diodes mounted on a first side of a printed circuit board, with wires for supplying power to the plurality of light-emitting diodes, said lens module comprising:
- a secondary lens array mounted over the plurality of light-emitting diodes on the printed circuit board, the secondary lens array comprising a body portion formed with at least one secondary lens element and with at least one sheath portion for the wires;
- and
- a lens holder mounted over the secondary lens array, the lens holder comprising a frame comprising one or more apertures, said frame being configured for accommodating the at least one secondary lens element in said one or more apertures, and said frame being configured for accommodating the at least one sheath portion and being configured to compress at least a portion of the secondary lens array to form at least one gasket at a periphery of the lens holder;
- wherein the printed circuit board is mounted on a base plate, and wherein the secondary lens array has a peripheral lip portion configured to extend over a surface of the base plate on which the printed circuit board is mounted, wherein the lens holder comprises a skirt portion arranged around its periphery, the skirt portion being configured for compressing the peripheral lip portion of the secondary lens array against the surface of the base plate;
- wherein the skirt portion has at least one cut-out portion therein, said at least one cut-out portion being configured to align substantially with the at least one sheath portion.
