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 and defining an aperture receiving the LED device therethrough such that the LED device protrudes beyond the front surface. 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 LED-apparatus assembly and a method for manufacturing custom high-efficiency LED lensing for LED-array modules. |
