Abstract

A method and apparatus for providing a strobe alarm unit employing at least one light emitting diode.

Claims (19)

1. A strobe notification appliance, comprising:

at least one broad distribution light emitting diode (LED);

an energy storage device for storing energy;

a control circuit for causing said stored energy to be applied to said at least one broad distribution LED, wherein said at least one broad distribution LED produces light of a predetermined color; and

a voltage converter coupled to the energy storage device.

2. A strobe notification appliance, comprising:

at least one broad distribution light emitting diode (LED);

an energy storage device for storing energy;

a control circuit for causing said stored energy to be applied to said at least one broad distribution LED, wherein said at least one broad distribution LED produces light of a predetermined color; and

a current limiter coupled to the energy storage device.

3. The strobe notification appliance of claim 2 , further comprising:

a buck converter coupled between the energy storage device and said at least one broad distribution LED.

4. A strobe notification appliance, comprising:

at least one broad distribution light emitting diode (LED);

means for storing energy;

means for controlling said means for storing energy for applying stored energy to said at least one broad distribution LED, wherein said at least one broad distribution LED comprises at least one white LED; and

means for converting voltage, coupled to said means for storing energy, for stepping an input voltage.

5. The strobe notification appliance of claim 4 , wherein said means for converting voltage comprises a buck converter.

6. The strobe notification appliance of claim 4 , wherein said means for converting voltage comprises at least one current limiting means.
