Abstract

The invention discloses an LED lamp which can be used in series with a thyristor sound control switch. The LED lamp includes a step-down capacitor, a current limiting NTC resistor, a sound control function maintaining capacitor, a rectifier, a filter capacitor, an LED group, a necessary safety device and a discharge resistor. The safety device, the step-down capacitor, the current limiting NTC resistor and the sound control function maintaining capacitor are connected to an AC power supply end in series, and the rectifier, the filter capacitor, the discharge resistor and the LED group are connected in parallel. According to the invention, the power frequency AC input is achieved with very low cost to drive LEDs to emit light, the problem that an ordinary LED lamp is incompatible with a large number of existing corridor thyristor voice control switches is solved, the LED lamp can be used for an ordinary 50Hz/60Hz power frequency AC power supply and is also compatible with a traditionalthyristor voice control switch, and incandescent lamps with high energy consumption and short lives can be completely substituted.

Description

technical field [0001] The invention relates to the field of LED lighting, in particular to an LED lamp which can be used in series with a thyristor voice control switch. Background technique [0002] It has been more than 100 years since Edison invented the tungsten lamp, and electric drive lighting has been used for more than 100 years. Compared with incandescent lamps and various gas discharge lamps, LED semiconductor lighting technology has gradually Popular in household, commercial, office and other fields. With the application of various lighting technologies, various dimming and switch controls are constantly developing in the direction of convenience and low cost. For example, there are a large number of SCR voice-activated switches in corridors. Designed for resistive load circuit characteristics, traditional energy-saving lamps cannot be used in series with this type of thyristor voice-activated switch because of their drive circuit has obvious capacitive or induc...
