Abstract

The invention discloses a lamp, which comprises a base, a pole, a lampshade, an LED driving circuit and an LED load, wherein the pole is flexible, the LED load is arranged on the top of the pole, and the LED driving circuit includes a mains power supply, a rectifying and filtering The circuit, the driving circuit, the output circuit and the feedback circuit are characterized in that they also include a regulating circuit, which is connected between the rectifying and filtering circuit and the driving circuit, and the LED strobe caused by the direct connection between the rectifying and filtering circuit and the driving circuit can be eliminated through the regulating circuit The problem.

Description

technical field [0001] The invention relates to the lighting field, in particular to an LED lamp. Background technique [0002] With the development of science and technology, LED, as a new type of light source, has the advantages of small size, low power consumption, high light efficiency, long life, environmental protection, etc., and is widely used in the field of lighting, and various LEDs have appeared Driving circuit, in practical applications, the use of different LED driving circuits will have an impact on luminous efficiency and life. [0003] At present, among many ways of driving LEDs, some use rectification and filtering circuits to directly connect with LED driving circuits to achieve efficient driving of LEDs. However, there are defects such as LED load flickering, easy damage, and strong high-frequency interference. caused inconvenience. In the application, the LED driving circuit needs to eliminate the stroboscopic problem caused by LED driving as much as p...
