Abstract
Abstract A flashing lantern (11) capable of emitting light through a 360-degree arc using LEDs as a light source is disclosed. The lantern comprises an array of LEDs (15) positioned in a substantially horizontal plane. An inverted conical reflector (19) is positioned above the array of LEDs (15) such that the apex of the reflector is pointed toward the array of LEDs (15). A fresnel-type lens (17) is positioned around the array of LEDs (15) and the conical reflector (19).

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
83 words
A flashing lantern comprising: (a) an array of light-emitting diodes mounted in a plane for emitting light in a direction perpendicular to the plane; (b) a reflector positioned to intersect the light emitted by said array of light-emitting diodes and redirect the light outwardly through a predetermined arc; (c) a magnifying lens surrounding said reflector; and (d) a control circuit for controlling the application of power to said array of light-emitting diodes such that said array of light-emitting diodes flashes on and off.
Claim 2
Dependent Claim
83 words
A flashing lantern comprising: (a) an array of light-emitting diodes mounted in a plane for emitting light in a direction perpendicular to the plane; (b) a reflector positioned to intersect the light emitted by said array of light-emitting diodes and redirect the light outwardly through a predetermined arc; (c) a magnifying lens surrounding said reflector; and (d) a control circuit for controlling the application of power to said array of light-emitting diodes such that said array of light-emitting diodes flashes on and off.
Claim 3
Dependent Claim
16 words
A flashing lantern as claimed in claim 1, wherein said predetermined arc is a 360-degree arc.
Claim 4
Dependent Claim
37 words
A flashing lantern as claimed in claim 2, wherein said reflector is a conical reflector positioned such that the apex of said conical reflector points toward said plane in which said array of light-emitting diodes is mounted.
Claim 5
Dependent Claim
39 words
A flashing lantern as claimed in claim 3, wherein said array of light-emitting diodes includes a plurality of sets of light-emitting diodes, said sets being connected in series, said sets including a plurality of light-emitting diodes connected in parallel.
Claim 6
Dependent Claim
75 words
A flashing lantern as claimed in claim 4, wherein said control circuit comprises: a metal oxide silicon field-effect transistor (MOSFET) connected in series with said array of light-emitting diodes; a power source connected to said MOSFET and said array of light-emitting diodes to supply power to said array of light-emitting diodes when said MOSFET is conducting; and a timer for supplying pulses to the gate of said MOSFET that cause said MOSFET to become conducting.
