Problems solved by technology

Because the single-stage structure of the LED drive power supply scheme has a high cost performance, most current LED lights use a single-stage isolated power supply. In this single-stage isolated power supply scheme, in order to ensure that the LED lights are turned off and other transient processes, For the stability of the power supply of the wireless module and the microprocessor, the existing preferred solution is to add an auxiliary power supply to supply power for the wireless module and the microprocessor separately, but this solution will lead to an increase in components and an increase in cost

Abstract

The embodiment of the invention provides an LED lamp. The LED lamp comprises a transformer and a wireless module which are connected with each other. The transformer comprises a primary coil, a first secondary coil and a second secondary coil, wherein the first secondary coil is used for supplying power to the LED loads of the LED lamp, and the second secondary coil is used for supplying power to the wireless module. The LED lamp further comprises a resistor R and a control switch SW. The resistor R and the control switch SW are connected in series with each other, and are connected in parallel with at least one LED load. When the wireless module sends a turn-off instruction, a continuity signal is sent to the control switch SW, and the control switch SW is switched on. Under the condition of cost control, the stability of power supply to the wireless module during turn-off period of the LED lamp and in other transient processes is ensured.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of lighting, and in particular to a light emitting diode (Light Emitting Diode, LED for short) lamp. Background technique [0002] Smart home lighting is an important part of the intelligent Internet of Things. More and more LED lights are equipped with microprocessors and wireless modules to realize smart home functions such as wireless connection and lighting control. Because the single-stage structure of the LED drive power supply scheme has a high cost performance, most current LED lights use a single-stage isolated power supply. In this single-stage isolated power supply scheme, in order to ensure that the LED lights are turned off and other transient processes, For the power supply stability of the wireless module and the microprocessor, the existing optimal solution is to add an auxiliary power supply to supply power for the wireless module and the microprocessor separately, ...
