Abstract
A LED light for replacing a fluorescent light in a fluorescent fixture is disclosed. The LED light is compatible with the existing fluorescent light fixture and ballast. The LED light includes a failure indicator to show whether a failure of the LED light is due to a failure of the ballast or a problem within the light. The LED light includes a color change mechanism, which may be controlled by an electromagnetic field or an input current to the LED light, thus making it compatible with current dimmer systems.
Claims13
A system for replacing a fluorescent light bulb with a light-emitting diode (LED) light bulb that is compatible with the existing fluorescent light ballast, the system comprising:
- a power connector configured to receive power from a fluorescent light ballast;
- a first LED configured to produce a first color of light, the first LED connected to the power connector;
- a second LED configured to produce a second color of light, the second LED connected to the power connector;
- a sensor connected to the power connector and configured to detect a magnetic field, the sensor further configured to activate the first LED when an electromagnetic field is not detected, the sensor still further configured to activate the second LED when an electromagnetic field is detected;
- and
- a failure LED configured to illuminate when at least one of the first LED and the second LED fails, the failure LED connected to the power connector.
