LED apparatus and method for accurate lens alignment

摘要

An LED apparatus of the type including (a) a mounting board having an LED-supporting surface with an LED device thereon and (b) a lens member over the LED device establishing a light path therebetween. The inventive LED apparatus includes a lens-aligning member having front and back surfaces. The lens member includes a lens portion and a flange thereabout, the flange being attached to the front surface of the lens-aligning member such that the lens portion substantially surrounds the protruding LED device. The lens-aligning member has a first mating feature which is positioned and arranged for mating engagement with a second mating feature of the mounting board, thereby accurately aligning the lens member over the LED device by accurately aligning the lens-alignment member with the mounting board. Other aspects of the invention is a method for assembly of an LED apparatus and a method for manufacturing custom high-efficiency LED lensing for LED-array modules.

主权项

1. An LED apparatus comprising:
a mounting board supporting at least one LED device thereon; at least one lens member corresponding to the at least one LED device; and a lens-aligning member having front and back surfaces with the at least one lens member being on the front surface, the lens-aligning member being between the mounting board and the lens member; and first and second alignment features, each in one of the mounting board and the lens-aligning member to align the at least one lens member over the corresponding LED device thereby establishing a light path therebetween.
