Problems solved by technology

[0002] The existing electronic ballasts have low power factor, high power consumption, poor anti-interference ability and low reliability, so they are not suitable for lighting lamps in special flammable and explosive environments such as mines and petrochemical industries.
Due to the need, the lighting lamps under the mine are always in the lighting state. Due to the low power factor of the ballast and high power consumption, the service life of the lighting lamps is reduced, and the lamp tubes need to be replaced frequently

Abstract

The invention discloses an electronic ballast and an energy saving lamp adopting the same and belongs to a lighting startup device. The ballast is provided with an active filter circuit, a rectification filter circuit connected with the active filter circuit, a high-frequency resonance circuit connected with the rectification filter circuit, and a load circuit connected with the high-frequency resonance circuit; a power factor correction circuit is connected between the rectification filter circuit and the high-frequency resonance circuit; and a negative feedback circuit is connected between the high-frequency resonance circuit and the load circuit. The electronic ballast is adopted by an illuminating lamp. The electronic ballast has the advantages of interference resistance, high power factor, high safety and reliability and long service life.

Description

technical field [0001] The invention relates to a start-up lighting device, in particular to an electronic ballast and an energy-saving lamp using the electronic ballast, which can be used for general lighting, and is especially suitable for lighting in inflammable and explosive environments such as mines and petrochemical industries. Background technique [0002] The existing electronic ballasts have low power factor, high power consumption, poor anti-interference ability and low reliability, and are not suitable for lighting lamps in special flammable and explosive environments such as mines and petrochemical industries. Due to the need, the lighting lamps under the mine are always in the lighting state. Due to the low power factor of the ballast and high power consumption, the service life of the lighting lamps is reduced, and the lamp tubes need to be replaced frequently. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the pr...
