The utility model has the advantages of simple circuit, low cost, etc., and the power saving fluorescent lamp is additionally provided with the light adjusting function.
Description
The utility model has related to a kind of tunable optical electronic energy-saving lamp, is specially adapted to the tunable optical electronic energy-saving lamp.
Why fully electronic energy-saving lamp in the market replace incandescent, and its main reason is that it can not be used for light modulation, can not be connected use with common dimmer (controllable silicon dimmer).At present both at home and abroad electronic energy-saving lamp can not light modulation, and reason has three: if the harmonic content height, power factor is low, and is big to Disturbance in Power Net.Its two, be that ballast is big to the impulse current of fluorescent tube, it is bright that fluorescent tube was hit in moment.Its three, be when line voltage is low, the voltage of lamp tube ends just is not to cause the initial ionization of gas in the pipe.So cause connecting the appearance that problems such as noise, flicker, damage are advanced in dimmer work.
The purpose of this utility model is to provide that a kind of circuit is simple, cost is low, performance is good, operating voltage range is wide, the electronic energy-saving lamp of noiselessness and flicker, tunable optical
The purpose of this utility model realizes by the following technical solutions: the utility model is a kind of common Voltage Feedback half bridge circuit, the utility model is made of anti-radio frequency interference circuit, bridge-type ballasting circuit, switch oscillating circuit, power saving fluorescent lamps etc., it is characterized in that a High Power Factor filter is connected with the bridge-type ballasting circuit by suppressing the fluorescent tube pulser, a suppressor pulse voltage divider is connected the power saving fluorescent lamps two ends.The High Power Factor filter reduces its pollution to electrical network significantly, improves power factor, reduction harmonic content, decay surge peak voltage.It is that dividing potential drop suppresses the impact of oscillating impulse to fluorescent tube that the suppressor pulse voltage divider mainly acts on, and dimming behavior is compensated.It is that fluorescent tube pulse voltage and ballast circuit are isolated that inhibition fluorescent tube pulse isolator mainly acts on, and makes the fluorescent tube high-voltage pulse not influence circuit working, and improves light modulation stability.
The utility model compared with prior art, it is simple to have a circuit, reduces cost, and makes electricity-saving lamp set up advantages such as dimming function.
Description of drawings of the present utility model is as follows:
Fig. 1 is circuit theory diagrams of the present utility model.
Below in conjunction with accompanying drawing the utility model is described in further detail: as shown in Figure 1, the utility model is made of anti-radio frequency interference circuit, bridge-type ballasting circuit, switch oscillating circuit, power saving fluorescent lamps etc., a High Power Factor filter is connected with the bridge-type ballasting circuit by suppressing the fluorescent tube pulser, and a suppressor pulse voltage divider is connected the power saving fluorescent lamps two ends.The High Power Factor filter connects into a series filtering circuit by C5, C9, D3, D4, D5, D6.A diode D13 constitutes inhibition fluorescent tube pulser and is connected between high power filter and the bridge-type ballasting circuit.The suppressor pulse voltage divider is made up of C3 and C24, and C24 one end connects an end of power saving fluorescent lamps, and C24 links to each other with the other end of power saving fluorescent lamps again with the common ends that is connected of C3.Civil power, carries out entering filter behind the ballast through the anti-radio frequency interference circuit that C8, C28, I2 form in bridge-type ballast D2, the High Power Factor filter reduces its pollution to electrical network significantly, improve power factor, reduce harmonic content, decay surge peak voltage.Enter the switch oscillating circuit after the filtering, the C3 in the circuit, C24 dividing potential drop suppress the impact of oscillating impulse to fluorescent tube, and dimming behavior is compensated.Isolate light tube electric voltage and ballast circuit with a diode D13, make the fluorescent tube high-voltage pulse not influence circuit working, and improve the stability of light modulation.
