20130119869 | SYSTEM AND METHOD FOR SUPPLYING CONSTANT POWER TO LUMINUOUS LOADS WITH POWER FACTOR CORRECTION - An apparatus is disclosed for supplying power to a luminous load. The apparatus includes a transformer having a primary winding, and a control circuit adapted to generate an alternating current through the primary winding to develop an alternating voltage. The alternating current is based on a first signal derived from the input voltage, a second signal derived from the current, and a third signal varying substantially in-phase with the input voltage. The first and second signals are used to regulate the power delivered to the load, and the third signal is used to improve the power factor. A load interface circuit is provided to generate an output voltage for the luminous load based on the alternating voltage from the transformer. An over-temperature sensor may be provided to cause a reduction in power to the load when the ambient temperature exceeds a threshold. | 05-16-2013 |
20120032605 | SYSTEM AND METHOD FOR DIMMABLE CONSTANT POWER LIGHT DRIVER - An apparatus is disclosed that is capable of delivering substantially constant power to a luminous load with variation in the input voltage and the environment temperature. The apparatus may be further adapted to vary the power supplied to the luminous load based on changes in the input voltage produced by a phase control dimmer or external device. Additionally, if the input voltage is changed due to a user controlling a dimmer device to control the brightness of the luminous load, the apparatus is able to control the power delivered to the load in response to the dimmer device. Additionally, the apparatus is adapted to allow the luminous output light intensity to be controlled by changes in a remote control voltage source or variable resister and draws near unity power factor power from the AC input throughout the dimming range when not used with phase control dimmer. The remote control or variable resistor can operate simultaneously with a dimmer to achieve multiple controls for the light output. | 02-09-2012 |
20110175532 | SYSTEM AND METHOD FOR SUPPLYING CONSTANT POWER TO LUMINUOUS LOADS - An apparatus is disclosed that is capable of delivering substantially constant power to a luminous load in response to variation in the input voltage and variation in the environment temperature. The apparatus may be further adapted to vary the power supplied to the luminous load in response to changes in the input voltage produced by a dimmer circuit. In other words, during non-dimming applications, the apparatus is able to maintain substantially constant power supplied to the load even though the input voltage and environment temperatures are varying during typical daily operations. Additionally, if the input voltage is changed due to a user controlling a dimmer device to control the brightness of the luminous load, the apparatus is able to control the power delivered to the load in response to the dimmer device. | 07-21-2011 |
