Abstract

The invention provides an LED power supplying device with a wide voltage input range and a wide load control range. The LED power supplying device comprises a power control processor, a PFC portion, a DC / AC converter, an LCC resonance converter, a voltage processing portion, and a current processing portion. By means of the power control processor capable of integrally controlling the LED power supplying device, power control can be effectively executed and the system composition of the LED power supplying device is simplified. Further, even though not being subjected to structure modification, the LED power supplying device may provides power for various LED modules and provide a wide voltage input range and a wide load control range. In addition, the invention may fix a voltage and current control manner and provides a power supplying device unequipped with an electrolytic capacitor.

Description

technical field [0001] The invention relates to an LED lighting power supply device, in particular to an LED lighting power supply device that provides efficient power supply for various LED modules and can perform power control. Background technique [0002] LED (light emitting diode) is a semiconductor element that can emit light. Due to its small size, long life, and excellent energy-saving effect, LED technology is used in the development of many lighting devices today. For the power supply of the lighting device, an SMPS (switching mode power supply) is used to supply driving power to the LED module. However, due to the characteristics of the supplied drive power, there may be an overload, which generates more heat and consumes more power. In addition, since an electrolytic capacitor is required to stabilize the output power, there is a problem that the life of the power supply device is affected by the life of the capacitor. Contents of the invention [0003] Probl...
