LED APPARATUS AND METHOD FOR ACCURATE LENS ALIGNMENT

摘要

An LED apparatus (10) of the type including (a) a mounting board having an LED-supporting surface (31) with an LED device (11) thereon and (b) a lens member (20) over the LED device establishing a light path (21) therebetween. The inventive LED apparatus includes a lens-aligning member (40) having front and back surfaces (41, 42) and defining an aperture (43) receiving the LED device therethrough such that the LED device protrudes beyond the front surface. The lens member includes a lens portion (22) and a flange thereabout (23), 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 (44) which is positioned and arranged for mating engagement with a second mating feature (34) of the mounting board (30), 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.
