Abstract
The utility model relates to a high efficiency electronic energy saving road lamp, relates to a lighting technology, and is suitable for street lamps. The aim of the utility model is to design a high efficiency electronic energy saving road lamp with long lifespan, low power consumption, high power factor and small current harmonic contents. The high efficiency electronic energy saving road lamp comprises electric network high voltage discharge branches R1 and C1, rectifying bridges D1 to D4, power factor correction branches C2, D5 and D6, high and intermediate frequency bur filtering branches L1 and L3, high frequency oscillating circuits BG1 and BG2, starting branches L2 and C7 and a lamp tube T which are connected orderly. Compared with the existing road lamp, the utility model can save power 80%, the harmonic contents THD are less than 25%, and the lifespan of the lamp tube can be prolonged by 3 to 4 times.
Description
The utility model relates to lighting technology, is applicable to the street street lamp.

The utility model purpose is to design a kind of long-life, low-power consumption, High Power Factor, the efficent electronic energy-conserving road lamp that current harmonic content is little.
The utility model purpose is achieved in that
A kind of efficent electronic energy-conserving road lamp comprises fluorescent tube, it is characterized in that the used power supply circuits of described fluorescent tube comprise the electrical network high pressure earial drainage branch road that is linked in sequence, rectifier bridge, power factor correction branch road, high intermediate frequency burr filter branch, high-frequency oscillating circuits, and start-up circuit.
The utility model advantage:
1, comparing in the past, street lamp can economize on electricity 80%;
2,,, can not damage fluorescent tube and power supply circuits thereof even line voltage moment rises to 300 volts because of high pressure earial drainage branch road is arranged yet;
3, harmonic content THD＜25%, because of high intermediate frequency burr filtering L1C3 is arranged, the utility model is noiseless to electrical network, and has improved power factor;
4, start branch road and used thermo-compensator R9 and delayed startup, give fluorescent tube, thereby prolonging lamp tube service life can reach 3-4 doubly with warm-up time.
In conjunction with the accompanying drawings, further specify the utility model content.
Fig. 1 the utility model circuit diagram.
Among the figure
T, fluorescent tube BG1, BG2, triode D1-D8, diode
