Description
Technical field
The present invention relates to a kind of gas discharge lamp ballast, more specifically to a kind of LC inductance of high-pressure mercury lamp
Electric capacitor ballast.
Background technology
In road lighting, the street lamp of the country more than 80% is high-pressure mercury lamp now, due to high-pressure mercury lamp luminous efficiency very
Height, reach 120 lumens/watts, develop also comparative maturity, so high-pressure mercury lamp occupies absolute leading position in road lighting.And
Nearly 2 years LED attempt to replace low power high-pressure mercury lamp, and at present, the luminous efficiency of high-pressure mercury lamp can guarantee that in 120 streams
It is bright/watt, but LED each side do it is relatively good could realize 100 lumens/watts, so LED in itself in the replacement of high-pressure mercury lamp not
Possesses advantage.
With the continuous development of electric lighting technology, there is LC high-voltage sodium lamp ballast, this ballast has energy-conservation
With good stabilized current characteristic and short circuit current it is small etc. many advantages of, it is affiliated because inductive-capacitive ballast has many good qualities
The technical staff of industry is carrying out the research that deepens continuously to him always.Such as《Chinese electric lighting》8th phase in 2002, (double gases were put
Electric light conjugation-type Inductive ballast);《Light source and illumination》4th phase in 2003 (design of LC ballasts);And Chinese patent
Patent publication No. CN201418192Y;Chinese patent patent publication No. CN201418193Y;Chinese patent patent publication No.
CN201054852Y;Chinese patent patent publication No. CN201156837Y.Deng these LC Energy-saving ballast technologies, which meet, works as prosthomere
The situation of energy emission reduction.However, there is an obvious shortcoming in LC high-voltage sodium lamp ballast, because the performance of high-pressure mercury lamp
Other discharge lamps are different from, high-pressure mercury lamp is 90V left in baseline in their entire life (1.2 ten thousand hours), modulating voltage
The right side, 160V or so can be risen to modulating voltage during end-of-life, because LC gas discharge lamp ballasts are when modulating voltage rises
The electric current of system is in the trend risen, this characteristic, for the gas-discharge lamp small to lamp voltage change, to gas-discharge lamp work
Make and the life-span does not all influence.But because high-pressure mercury lamp is very big in the voltage change of whole lifetime lamp, according to above-mentioned LC high pressures
The characteristic of sodium lamp ballast, the service life of high-pressure mercury lamp will be directly affected.
