Abstract

The invention belongs to the field of electronic lighting and provides an LED driving circuit and an LED lamp. According to the LED driving circuit and the LED lamp, due to the facts that the LED driving circuit which is composed of a voltage dividing filtering module, a first flyback driving module, a second flyback driving module, a secondary rectification filtering module, an electrical parameter detection and feedback module, an isolation transmission module and a switch power circuit module is applied, the two flyback driving modules which are connected in series bear the same voltage output and the same power output, and sufficient electricity drive can be provided for a high-power LED load under the condition that the application of a high-power transformer is not needed, the power loss is low, the utilization rate of electric energy is high, and the circuit cost is low. Therefore, the problems that the utilization rate of electric energy is low, the power loss is high and cost is high in the prior art are solved.

Description

Technical field [0001] The invention belongs to the field of electronic lighting, and in particular relates to an LED drive circuit and an LED lamp. Background technique [0002] At present, as a new type of light source, LED has been widely used in various fields due to its advantages of low energy consumption, strong brightness and long life. [0003] In the existing high-power LED lamps (rated power above 150W), the forward circuit is generally used to drive the LED light, and the forward circuit needs to use a high-power transformer and a high-voltage drive MOS tube, so the entire forward circuit The power consumption is high and the cost is high. In the existing low-power LED lamps (rated power below 150W), a single flyback circuit is used to drive the LED to achieve the purpose of lighting. However, the flyback circuit is driving the LED The power consumed during lighting is relatively high, which in turn will lead to a reduction in the power efficiency of the whole machine....
