The disclosed technology relates to a hard and soft light module having a housing with a first surface that accommodates a lens. A first plurality of LEDs are disposed along a periphery of the first surface, the first plurality of LEDs are configured to generate light in a first direction toward an edge of the lens. A second plurality of LEDs are disposed proximate to the first surface, the second plurality of LEDs are configured to generate light in a second direction through the lens. The first plurality of LEDs are configured to generate a soft light and the second plurality of LEDs are configured to generate a hard light.

Hard and soft light module with ambient light sensing

A system to predict a fatigue life of an aluminum alloy is disclosed herein. The system comprises a computer-readable medium cooperative with micromechanics-based fatigue life models for cyclic multiaxial loading. The fatigue life models predict the fatigue life by processing information received by the system relating to the aluminum alloy and the stress state present in the aluminum alloy. The received information comprises at least one of: a critical shear plane, a damage factor, a hardening factor defined by at least one of a plurality of uniaxial cyclic hardening factor parameters related to probabilistics of defects and microstructure characteristics in the aluminum alloy, an additional hardening factor related to non-proportionality, and thermophysical and mechanical properties of the aluminum alloy. The defects and microstructure characteristics can be calculated using mathematical modeling of casting, solidification and heat treatment processes or by an extreme value statistics based on metallography measurements.
