Abstract
A light emitting diode (“LED”) module is disclosed. The LED module includes a first LED tap and a second LED tap, the first tap being powered on for a longer amount of time than the second LED tap, based on an alternating current voltage. The LED module also includes a first LED package on which a first LED associated with the first LED tap and a second LED associated with the second LED tap are disposed. The LED module further includes a second LED package on which a third LED associated with the first LED tap and a fourth LED associated with the second LED tap are disposed.
Claims20
A light emitting diode (“LED”) module comprising:
- a first LED tap and a second LED tap, the first LED tap being powered on for a longer amount of time than the second LED tap, based on an alternating current voltage;
- a first LED package on which a first LED associated with the first LED tap and a second LED associated with the second LED tap are disposed;
- and
- a second LED package on which a third LED associated with the first LED tap and a fourth LED associated with the second LED tap are disposed,
- wherein the second LED package is disposed a distance along a housing from the first LED package such that the LEDs of the first LED package appear approximately as a point light source and the LEDs of the second LED package appear approximately as a point light source, to average out lighting variations provided to the first LED tap and the second LED tap.
A method for driving a light emitting diode (“LED”) module, the method comprising:
- powering on a first LED tap for a longer amount of time by an alternating current voltage than a second LED tap;
- powering, via the first LED tap, a first LED disposed on a first LED package;
- powering, via the second LED tap, a second LED disposed on the first LED package;
- and
- powering a third LED associated with the first LED tap and a fourth LED associated with the second LED tap, the third LED and fourth LED being disposed on a second LED package,
- wherein the second LED package is disposed a distance along a housing from the first LED package such that the LEDs of the first LED package appear approximately as a point light source and the LEDs of the second LED package appear approximately as a point light source, to average out lighting variations provided to the first LED tap and the second LED tap.
A light emitting diode (“LED”) installation comprising:
- a housing, in which is disposed:
- a first LED tap and a second LED tap, the first LED tap being powered on for a longer amount of time than the second LED tap, based on an alternating current voltage;
- a first LED package on which a first LED associated with the first LED tap and a second LED associated with the second LED tap are disposed;
- and
- a second LED package on which a third LED associated with the first LED tap and a fourth LED associated with the second LED tap are disposed,
- wherein the second LED package is disposed a distance along a housing from the first LED package such that the LEDs of the first LED package appear approximately as a point light source and the LEDs of the second LED package appear approximately as a point light source, to average out lighting variations provided to the first LED tap and the second LED tap.
