The present invention discloses an aspherical LED angular optical lens for wide distribution patterns and an LED assembly using the same. In particular, the invention relates to compressed gas energy storage and recovery systems using staged pneumatic conversion systems for providing narrow pressure ranges to a hydraulic motor. The stacked storage capacitor structure further comprises a third conductive layer including a first portion and an extended second portion. Material to be trimmed is placed between the recessed cutting track and the guide track. In one embodiment, layers of BMG can be cut from one or more sheets of BMG to desired shapes, stacked and fused to form the part.
