Abstract

The invention provides a split type multi-energy-saving lamp illumination system. The system is formed by connecting a bridge-type output end of a rectifying circuit to a high-frequency transformation circuit, then connecting the half-bridge output of the high-frequency transformation circuit to a filter circuit, and finally connecting to a driving circuit. The invention comprises the following steps: firstly, rectifying an AC and correcting by adding APFC power; then, carrying out high-frequency transformation and adding frequency modulation to adjust light to obtain the high-frequency AC; and finally connecting to a plurality of driving circuits by LC filtration to respectively drive a plurality of energy-saving lamps. By adopting the technical scheme, one high-performance ballast can drive a plurality of energy-saving lamps, and has the light-adjusting function without additionally arranging control circuits on the lamps. The split type energy-saving lamps have high power factors for avoid adding APFC circuit corrected power on each lamp. Due to the reasons, the split type energy-saving lamps can use less electronic parts, decreases the size and the finished products, has low working temperature and longer electronic part service life than that of a common energy-saving lamp and reduces the generation of electronic garbage so as to be environment-friendly and energy-saving and have practical values.

Description

Technical field:

[0001] The invention relates to the technical field of family and public safety lighting, in particular to a ballast with a fire sensing function. Background technique:

[0002] Ordinary energy-saving lamps, electronic components and lamp tubes are integrated. Due to the limitation of volume and cost, the working temperature is high, the life of electronic components is short, and the lamp tubes are aging or damaged. Not conducive to environmental protection. If the dimming function is added to ordinary energy-saving lamps, a control circuit must be added to each lamp, which will inevitably lead to an increase in size and cost. Ordinary energy-saving lamps have a low power factor. To improve the power factor, an APFC circuit must be added to correct the power of each lamp, which will increase the size and cost of the product. Invention content:

[0003] The object of the present invention is to overcome the disadvantages of the prior art, and provide a s...

Embodiment Construction

[0009] Below in conjunction with a preferred embodiment of the present invention and accompanying drawing, the present invention will be further described:

[0010] In this embodiment, the bridge output end of the rectifier circuit is connected to the high-frequency conversion circuit, the half-bridge output of the high-frequency conversion circuit is connected to the filter circuit, and finally the drive circuit is connected. Such as figure 2 As shown, the present invention first rectifies the alternating current, can add APFC power correction, then performs high-frequency conversion, can add frequency modulation and dimming to obtain high-frequency AC, and then filters through LC, and finally connects multiple driving circuits to drive multiple energy-saving lamps. as attached figure 1 As shown, transformer T1, C23, C24, and R27 form a filter circuit for alternating current, C23 and R27 are connected to terminals 1 and 2 of T1 in parallel, and C24 is connected to terminal...
