Abstract: The breath synchronization lighting devices and apparatus helps the user to regulate their breathing rate by moving a light source with respect to a stationary shade or cover. The shade or cover, optionally perforated or with an integrated obscuring pattern, partially blocks the light created by the light source. The result is the generation of a shadow pattern on adjacent surfaces. As the light moves with respect to the cover, the shadow pattern correspondingly moves on the surface is surrounding the device. The result is a cycling shadow pattern on adjacent surfaces, the pattern timed to match the ideal breathing rate of the user, helping the user to slow their breathing and reach a calm and meditative state.

Abstract: An example joiner system for joining a first section and a second section of a fixture includes a joiner bracket that has formed therein a depressed ramp region. A joiner fastener, such as a screw, may engage against the angled walls of the joiner bracket ramp, to translate the vertical movement of the screw into a horizontal, longitudinal movement of the joiner bracket.
