摘要：
An intrinsically safe flashlight (100) includes a housing (100), a battery receiving region (108), an active electrical circuit (202), and a light source (118). The active electrical circuit (202) uses energy from batteries (110) received in the battery receiving region (110) of the flashlight (100) to power the light source (118). The electrical circuitry of the flashlight (110) is energy limited so that the flashlight is intrinsically safe for use in hazardous locations.
