Description

High-efficency electronic energy-saving lamp

The utility model belongs to energy-saving lamp.

For energy savings, study and produced various types of energy-saving lamps.A kind of energy-saving daylight lamp is made up of iron inductance ballast, starter, fluorescent tube, lamp tube socket.This lamp is compared with general incandescent lamp energy-conservation effect, the lamp luminescence effect height that wattage is identical.But have following shortcoming: 1. pair supply voltage is had relatively high expectations; Voltage is lower than 190V can not starter, is higher than the 220V filament and very easily blows; 2. the iron core of ballast produces the hum of 50Hz, and the stroboscopic effect of 50Hz is arranged behind the starter, and long-time the use is harmful to eyesight; 3. fluorescent tube only could starter behind filament pre-heating, so fluorescent tube has four lead-in wires, and is wherein a pair of to the heater chain power supply, and seals in starter, and operate as normal just behind the starter is given to install and use and made troubles, even can damage fluorescent tube; 4. often can not accomplish disposable starter, the ability starter that especially need glimmer 2～4 times when ambient temperature is low influences lamp tube service life; 5. use inconvenience, must load onto or unload the lamp holder interface when incandescent lamp and fluorescent lamp exchange are used; 6. loss is big, and only ballast itself will power consumption 5～7W.

The purpose of this utility model will overcome above-mentioned shortcoming exactly, designs a kind of energy-efficient, easy to install, long-life, in the harmless light fixture of health especially eyesight.

The light fixture of the utility model design is made up of lamp holder (4), electronic starter (3), fluorescent tube (1) and lamp tube socket (2).Supply voltage feeds electronic starter by lamp holder, and fluorescent tube is contained on the lamp tube socket of connecting with electronic starter.Electronic starter comprises power rectifier circuit (5), frequency conversion drive circuit (6) and the ballasting circuit that boosts (7).Frequency conversion drive circuit (6) adopts self-excitation unsaturation formula oscillating circuit, and the ballasting circuit that boosts is LC series resonant circuit and high frequency choke coil.The effect of power rectifier circuit is the direct current that the AC rectification of 220V, 50Hz is filtered into 300V, behind this direct current input frequency conversion drive circuit, through the frequency conversion output frequency is the square wave of 20～30KHz, to export the frequency and the instantaneous voltage raising of square wave again through the ballasting circuit of forming by LC series resonant circuit and high frequency choke coil that boosts, make gas ionization in the fluorescent tube and starter, instantaneous high pressure peak value operating state when the 300V left and right sides is best, about frequency should double, the fluorescent tube normal working voltage was about 100V.Lamp holder is general commercially available various convenience goods.

For self-excitation unsaturation formula oscillating circuit is triggered, can use a diac to form instantaneous square tooth ripple and cause that oscillating circuit produces vibration, vibration inductance core ferrite high frequency diplopore magnet ring.

For improving the frequency and the instantaneous voltage of output square wave, can utilize the phase difference of LC series connection in the LC series resonant circuit to realize that wherein the C among the LC should be in parallel with fluorescent tube.The high frequency choke coil that plays metering function can adopt general commercially available prod, as using ferrite E type high frequency magnetic core better effects if.For further improving power saving rate, replace common fluorescent tube with energy-efficient fluorescent tube.

Use the light fixture of the utility model design to have following advantage.

Fluorescent tube can one time starter, do not glimmer, do not need filament pre-heating, so lamp tube service life is long generally can reach 6000～8000 hours, is 2～3 times of iron inductance ballast fluorescent lamp.

2. light fixture little power consumption, the luminous efficiency height of the utility model design.Compare with the light fixture of inductance type ballast, power factor can bring up to 0.9, and loss is its 10% only, and brightness can improve 25%, therefore can economize on electricity 30%.

3. the scope of application of supply voltage and ambient temperature is wide, and voltage is between 130～250V, but ambient temperature is in-25～50 ℃ of down equal starters and operate as normal.

4. do not have peak sound, no 50Hz stroboscopic effect, be fit to people and under long-time illumination, work.

5. lamp installation of the present utility model is simple, easy to use, the lamp holder interface adapted of can be directly using with former incandescent lamp, and light fixture weight only is 15% of Inductive ballast light fixture.
