1. A compact, portable lighting system, comprising:
a housing; a power source carried by said housing; a primary source of illumination carried by said housing for providing an illuminated path of light, said primary source of illumination comprising a light emitting diode emitting white light and powered to shine brightly; a microprocessor carried by said housing; an ambient light sensor carried by said housing, said ambient light sensor providing a first input signal to said microprocessor when ambient light falls below a first predetermined level; a motion sensor carried by said housing, said motion sensor comprising a three axis accelerometer measuring movement in three dimensions, said motion sensor providing a second input signal to said microprocessor when said housing undergoes motion above a predetermined motion level in any one of said three dimensions; said microprocessor switching power from said power source to said primary source of illumination upon receiving both said first and second input signals and thereby causing said primary source of illumination to provided said illuminated path of light; a pulsed low power, low lumen locating light carried by said housing and operable only below a second predetermined level of ambient light and only below said predetermined motion level, said pulsed low power, low lumen locating light comprising a night light for locating said lighting system in the dark; and a first user actuated switch carried by said housing and which selectively enables and prevents illumination of said pulsed low power, low lumen locating light and allows a user to selectively turn off said night light to facilitate sleep. |
