Digital energy-saving lamp circuit

Abstract

The invention relates to the technical field of energy-saving lamp circuits, in particular to a digital energy-saving lamp circuit. The circuit comprises a rectifier circuit used for converting an alternating current into a direct current and an inverting circuit used for converting the direct current into the alternating current for starting an energy-saving lamp tube, and is characterized by also comprising a control circuit, wherein the control circuit comprises two half-bridge power transistors, a level shifter, a power tube driver, a bootstrap circuit, an internal low-voltage power supply, a self-excited oscillator and starting and frequency-sweeping functions required by soft start and preheating; and the inverting circuit is connected with the power output end of a 2024 integrated circuit. As the integrated circuit generates a driving signal for the internal self-excited oscillator, the frequency is very stable. The power tube runs in an alternate mode, so that the power tube has longer relative service life.

Description

Technical field: [0001] The invention relates to the technical field of energy-saving lamp circuits, in particular to a digital energy-saving lamp circuit. technical background: [0002] Energy-saving lamps have many advantages such as energy saving and environmental protection. Now they are used more and more widely, and there are more and more types. Energy-saving lamps are used in lighting facilities in many public places, such as government agencies, units, and residences. However, most of the existing energy-saving lamps are composed of discrete components and transformers. It is a permanent product, so the working frequency of the circuit is unstable, the reliability is not high, and the cost is high, which makes it difficult to popularize and is not conducive to the development of energy-saving lamps. Invention content: [0003] The object of the present invention is to provide an energy-saving lamp circuit. The energy-saving lamp circuit is composed of an integrat...
