Abstract
A portable lighting and warning device includes: a housing; a lighting generator unit; a sensor unit sensing shaking of the housing to generate a sense output; a mode selector unit generating a mode indication signal; a warning generator unit; and a controller unit. In a case where the mode indication signal indicates a lighting mode, the controller unit controls the lighting generator unit to emit light. In a case where the mode indication signal indicates a warning mode, the controller unit waits for a predetermined pause time, and then controls the warning generator unit and the lighting generator unit to output sound and emit light when the sense output corresponds to the shaking of the housing not less than a predetermined level in intensity.
