Abstract

A smartphone casing with an LED flashlight unit and battery pack. The casing is sized to partially encapsulate the shell of a smartphone. The back wall includes an LED light unit coupled to a battery pack. An LED activation button provides a direct coupling between the battery pack and the LED light unit. The power pack independently stores electrical power in its lithium-ion pack. There are 5 sequential modes. The first three modes initiate light emission at 600* lumen, 400* lumen and 200* lumen. The fourth mode is termed a Strobe Self-Defense to stifle and hinder an assailant in a hostile situation. The fifth mode is a Beacon to give a signal of emergency.
