Abstract

The invention is applicable to the LED lighting circuit field, and particularly relates to an LED single-key switch control circuit and an LED lighting. In an embodiment of the invention, the LED single-key switch control circuit is simple, reliable, low-cost and stable in operation. When connected, the LED single-key switch control circuit cannot generate a heavy instantaneous current, thereby avoiding sparkling, oxidation, bad contact and the like; further, the LED single-key switch control circuit has a far better reliability than a mechanical switch and is particularly applicable to small electronic products.

Description

technical field [0001] The invention belongs to the field of LED lamp circuits, in particular to an LED single-key switch control circuit and an LED lamp. Background technique [0002] As a new light source, LED has the characteristics of energy saving, environmental protection and high efficiency. The technology has matured and is applied in various fields. LED is widely used as a lighting source. [0003] At present, many electronic products, including LED lamps, use mechanical switches to directly switch the power supply. Since the mechanical switch will generate a large instantaneous current when it is turned on, the contacts of the switch shrapnel are prone to ignition, and ignition is easy to make the contacts Oxidation causes poor contact of the mechanical switch, which may lead to failure of the function of the mechanical switch. Contents of the invention [0004] The purpose of the present invention is to provide a LED single-key switch control circuit, aiming to...
