SUPER POWER-SAVING LED ILLUMINATION LAMP EMITTING LIGHT BASED ON MICRO-CURRENT

摘要

A super power-saving LED illumination lamp emitting light based on a micro-current, comprising a power supply module IC externally connected to a mains alternating-current power supply, a voltage dividing resistor R3 and an LED luminous body. The power supply module IC provides a current for driving the LED luminous body. The power supply module IC comprises four terminals, the four terminals including a first terminal (1), a second terminal (2), a third terminal (3) and a fourth terminal (4). The first terminal (1) is externally connected to a live wire of the mains alternating-current power supply, the second terminal (2) is externally connected to a null wire of the mains alternating-current power supply, the third terminal (3) is connected to a first end of the luminous body via the voltage dividing resistor R3, and the fourth terminal (4) is connected to a second end of the luminous body. The power supply module IC comprises a resistor R1, a resistor R2, a voltage conversion unit and a rectification and current stabilization unit. A current stabilization module HC comprises resistors R4-R8, diodes D1 and D2 and a MOS transistor Q2. The LED illumination lamp has advantages of being able to provide a good illumination effect with a very low micro working current, giving out a low quantity of heat, having low production costs and a long service life, etc.
