Abstract

The invention relates to a driving power supply, in particular to a transformer contained driving power supply for an LED lighting system. The driving power supply comprises a transformer and circuit boards, wherein a secondary control circuit and a primary control circuit of the transformer are arranged on the circuit boards, and the circuit boards include a first circuit board, a second circuitboard and a third circuit board, wherein the first circuit board and the second circuit board are basically arranged in parallel vertically, the bottom end of the first circuit board is fixedly connected with a terminal post of a secondary output port of the transformer, and the bottom end of the second circuit board is fixedly connected with a terminal post of a primary input port of the transformer; both ends of the third circuit board are fixed between the top ends of the first circuit board and the second circuit board in a bridge connection mode. Because of the technical characteristics and advantages, the driving power supply can be applied to an LED driving power supply product requiring a compact structure.

Description

technical field [0001] The invention relates to a driving power supply, in particular to a driving power supply for an LED lighting system containing a transformer. Background technique [0002] With the development of LED lamp lighting technology, LED has been applied in many occasions such as household appliances, general lighting, and street lamps. The existing driving power supply for LED lights, like the power supply used in other occasions, generally includes a transformer and a circuit board, and the circuit board is provided with a secondary control circuit and a primary control circuit electrically connected to the transformer. However, when this kind of driving power is applied to lighting lamps and other appliances, the driving power is generally placed in the lamp holder. Therefore, the driving power needs to be miniaturized as much as possible so as to adapt to the existing specifications of the lamp holder. For example, the application number is 200520067509.4...
