Special energy-saving module for daylight lamps or fluorescent lamps

Abstract

The invention relates to a special energy-saving module for daylight lamps or fluorescent lamps, which is suitable for electronic circuits of various illuminating daylight lamps or fluorescent lamps, such as a 5-40WT8 lamp tube, a T5 light tube, a U-shaped light tube, an annular light tube, a spiral light tube and the like. For most of the energy-saving daylight lamps or the energy-saving fluorescent lamps in the market at present, discrete devices are adopted; the energy-saving ratio is between 40% and 50% commonly and the power factor is between 0.5 and 0.6; the circuit has a high heating value; the energy consumption is much so as to influence the electric quality, and moreover, a production process is complex so that the production cost is increased. As shown in an attached figure in the specification, the invention provides the module, which is simple and easy for operation, has low cost, high energy-saving ratio and improved electric quality and is characterized by employing a harmonic filtering current-follow-up circuit, a frequency energy feedback circuit and an output control circuit to improve the power factor from the original about 0.6 to about 0.95; the energy-saving ratio reaches up to more than 70%; the module realizes the extreme energy-saving effect; and the module is also characterized by reducing 60% of elements of the circuit, ensuring simple and convenient production process, improving the production efficiency and reducing the production cost.

Description

Technical field: [0001] The invention relates to a special energy-saving module for fluorescent lamps or fluorescent lamps, which is suitable for various lighting circuits of fluorescent lamps or fluorescent lamps such as 5-40W T8 lamp tubes, T5 lamp tubes, U-shaped lamp tubes, ring lamp tubes, and spiral lamp tubes. Background technique: [0002] At present, the energy-saving fluorescent lamps available in the market are all discrete components, the power saving rate is low, generally between 40% and 50%, the power factor is generally between 0.5 and 0.6, the heat generation is large, the power loss is quite large, and directly affects Power quality. Invention content: [0003] The present invention provides a special module which is easy to mass-produce, low in price, small in calorific value, high in power saving efficiency, greatly improves power factor, reduces current harmonic distortion, and maximizes power quality. The object of the present invention is achieved i...
