Abstract
Official abstract text for this publication.
The present invention relates to a lighting apparatus driver, comprising: a filter, which is used to filter out noise; a rectifier, which is used to convert an alternating current voltage into a direct current voltage; and a plurality of voltage regulator integrated circuit (IC) modules, which are directly or indirectly connected to the rectifier, wherein each one of the plurality of voltage regulator IC modules is used to connect to a separate lighting apparatus, so that each one of the plurality of voltage regulator IC modules can independently control the electric current inputted into the lighting apparatus connected thereto.
First claim
Opening claim text (preview).
What is claimed is: 1 . A lighting apparatus driver, comprising: a filter to filter out noise; a rectifier to convert an AC voltage into a DC voltage; a plurality of voltage regulator IC modules connected to the rectifier directly or indirectly, wherein each of the plurality of voltage regulator IC modules is to be connected to a separate lighting apparatus, such that each of the plurality of voltage regulator IC modules is capable of independently controlling current input to the lighting apparatus connected thereto. 2 . The lighting apparatus driver according to claim 1 , wherein the plurality of voltage regulator IC modules are Buck modules or FlyBack modules. 3 . The lighting apparatus driver according to claim 1 , wherein the lighting apparatus driver further comprises a dimming control, and the dimming control is coupled to each of the plurality of voltage regulator IC modules, so as to send a dimming control signal to each of the plurality of voltage regulator IC modules. 4 . The lighting apparatus driver according to claim 3 , wherein when the dimming control signal is to cause brightness of each of multiple lighting apparatuses to change, the dimming signal is sent to each of the plurality of voltage regulator IC modules, and each voltage regulator IC module independently inputs substantially the same current to the lighting apparatus connected thereto, such that the brightness of each of the multiple lighting apparatus is substantially the same. 5 . The lighting apparatus driver according to claim 3 , wherein the dimming control is isolation dimming control. 6 . The lighting apparatus driver according to claim 5 , wherein the isolation dimming control is magnetic dimming control or optocoupler based dimming control. 7 . The lighting apparatus driver according to claim 3 , wherein the control signal is in a form of voltage or is based on a DALI protocol. 8 . The lighting apparatus driver according to claim 1 , wherein each of the voltage regulator IC modules comprises a metal oxide semiconductor field effect transistor (MOSFET). 9 . The lighting apparatus driver according to claim 1 , wherein the lighting apparatus driver does not include a half bridge. 10 . The lighting apparatus driver according to claim 1 , wherein the lighting apparatus driver is to drive a plurality of LED lamps connected in parallel. 11 . The lighting apparatus driver according to claim 10 , wherein the LED lamps have different sizes and/or power. 12 . The lighting apparatus driver according to claim 1 , further comprising a Boost module to boost a rectified voltage. 13 . The lighting apparatus driver according to claim 12 , wherein the Boost module is coupled between the rectifier and the plurality of voltage regulator IC modules. 14 . The lighting apparatus driver according to claim 1 , wherein the rectifier is a rectifier bridge.
