Abstract

Exemplary security lighting routines are tailored to disrupt visual perception and/or acuity so as to significantly reduce the ability of a person or persons, who has breached security, to function within a secured space. A routine triggered in response to a security breach includes a flash at a relatively high intensity, some number of times brighter than normal illumination for the space. Some exemplary routines include a warning light and/or a pre-flash light emission such as dim lighting or a flicker, to effectively prepare the person in the space for maximum effectiveness of the flash. Exemplary routines may also include a post-flash sequence of multiple color light emissions, such as alternating emissions in sequence of pulses of different colors of light using emission and/or off time parameters that vary in an irregular manner.
