Abstract

The invention discloses a sectional type LED dimming lamp without an externally arranged dimmer and a dimming method of the sectional type LED dimming lamp without the externally arranged dimmer. The sectional type LED dimming lamp without the externally arranged dimmer comprises a bulb structure. A dimming circuit is arranged and fixed in the bulb structure. The dimming circuit comprises a rectifier bridge electrically connected with alternating current in a city through a power source switch and an LED lamp control output circuit connected with the rectifier bridge in a direct current outputting mode. The LED lamp control output circuit comprises a high-frequency transformer composed of a primary coil, a secondary coil and a magnetic core, a pulse generator used for driving the primary coil to vibrate and a sectional dimming control circuit. The primary coil supplies power for driving an LED tube to emit light. The second coil supplies direct current for the pulse generator with pulse width adjustable and the sectional dimming control circuit through a rectifying circuit. The sectional type LED dimming lamp is simple in structure, small in the number of high-frequency transformer windings, capable of the achieving dimming function of the lamp, free of adding the dimmer and capable of completely achieving the technology of dimming through a switch, reducing cost and increasing reliability of the circuit.

Description
