Light emitting device with self-aligning preformed lens

A lens structure is pre-formed with features that facilitate accurate alignment of a light emitting chip within the lens structure. To ease manufacturing, the features include tapered walls that allowfor easy insertion of the light emitting chip into the lens structure, the taper serving to accurately align the light emitting chip when the chip is fully inserted. The taper may include linearly sloped or curved walls, including complex shapes. An adhesive may be used to secure the light emitting chip to the lens structure. The light emitting chips may be picked-and-placed into an array of lensstructures, or picked-and-placed onto a substrate that may be overlaid by the array of lens structures. 一种透镜结构以促进在该透镜结构内发光芯片的精确对准的特征被预先形成。为了便于制造，特征包括允许发光芯片容易插入到透镜结构中的锥形壁，该锥形物用来在芯片完全插入时精确地对准发光芯片。该锥形物可以包括线性倾斜或弯曲的壁，其包括复杂形状。可以使用粘合剂来将发光芯片固设到透镜结构。发光芯片可以被拾取和放置到透镜结构的阵列中，或者被拾取和放置到可以被透镜结构的阵列覆盖的衬底上。
