Description

The energy-saving, service life prolonged electronic starter of fluorescent lamp

The energy-saving, service life prolonged electronic starter of the utility model fluorescent lamp, what relate to is the starter that uses on all types of Inductive ballast fluorescent lamps.

The Inductive ballast fluorescent lamp, the old starter of use, its structure is to form with the neon bulb shunt capacitance.The interior electrode contacts of neon bulb produces closure during startup under supply voltage, connects fluorescent lamp circuit work, and its electric current adds to cathode fluorescent tube fervid degree rapidly, forms high-voltage pulse and starts fluorescent lamp, once in use has following shortcoming:

1. dangerous energy-conservation: show when voltage is lower than the starter rated value, or fluorescent tube matter difference and aging opening when motionless, starter does not have the function of automatically shutting down, and the circuit power consumption is not still connected because of losing voltage in the contact; Because the shunt capacitance of starter easily punctures and the interior contact of neon bulb easy burn-out causes short circuit, not only the power consumption electric current is big, even burns out ballast and cause accident.

2. easily make fluorescent tube aging: stroboscopic to occur during owing to startup, whenever open a lamp and make fluorescent tube shorten 4～8 hours life-spans; When if supply voltage surpasses the starter rated value, starting current increases, and surpasses the fluorescent tube rated value, is directed at and burns out fluorescent tube or premature ageing.

3. useful life is short: 6000 cycles of nominal life, but must in rated voltage 180V～250V scope, work, because peak period and low ebb phase often appear in line voltage, to starter and fluorescent tube are often burnt out.

Producing above-mentioned reason is because the interior electrode contacts closed resistance of old starter neon bulb is relevant with mains voltage variations, be voltage when high closed resistance little, cause the fluorescent lamp starting electric current to increase, closed resistance was big when voltage was low, cause the fluorescent lamp starting electric current little and can not work, so the failure rate height.

The purpose of this utility model is to provide a kind of technical performance superior energy-saving, service life prolonged electronic starter at the above-mentioned weak point of old-fashioned starter, it is to adopt phase-shift pulse to trigger the conducting of controllable silicon current limliting, be not subjected to the influence of mains voltage variations, fluorescent lamp to different capacity all can be stabilized in the specified starting current, can make the fluorescent tube long-term stable operation.

Elaborate below in conjunction with the circuit structure and the principle of accompanying drawing the energy-saving, service life prolonged electronic starter of the utility model fluorescent lamp:

This circuit adopts element of one-way SCR TS to make the starter master switch; Neon bulb TD, resistance R ₁, capacitor C ₁, four elements such as voltage-stabiliser tube DW are formed sinusoidal wave phase-shift pulse generator; By diode D, resistance R ₂, R ₃, electrochemical capacitor C ₂, C ₃Form and trigger controllers Deng five elements, by above three partial circuits totally ten electronic components be installed in old starter and mould in the housing of formula aluminum hull and other shapes in the shell, constitute the energy-saving, service life prolonged electronic starter of fluorescent lamp (the finished product structure is seen Fig. 2).Insert fluorescent lamp circuit by Fig. 1 when the user uses, promptly Fig. 2 finished product inserts old starter position startup fluorescent lamp operation.

Operation principle is seen Fig. 1, and when the K switch energized, the 220V alternating voltage ends owing to the controllable silicon internal resistance greatly temporarily is in to fluorescent lamp Y two ends filament to one-way SCR negative electrode anode tap through ballast Z, the fluorescent lamp circuit access failure, and no current passes through, wouldn't starter.Exchange V at the same time ₁Through neon bulb TD to capacitor C ₁Charging, VC ₁Crest voltage is through resistance R ₁Current limliting forms sinusoidal wave phase-shift pulse after the voltage-stabiliser tube DW dividing potential drop, the voltage-stabiliser tube DW diode of holding concurrently ends when exchanging positive half cycle, diode D conducting, and first positive pulse signal is through electrochemical capacitor C ₂Coupling adds to one-way SCR TS control and extremely goes up, trigger the controllable silicon conducting, because negative electrode, the anode of one-way SCR are connected with fluorescent lamp two ends filament, be equivalent to the old starter closing of contact after the controllable silicon conducting, immediate current adds to fervid degree with the cathode fluorescent tube filament, produce electrion, fluorescent lamp starter, VC at this moment ₁Continue through diode D to electrochemical capacitor C when pulse signal, positive half cycle ₂, C ₃Charging is because electrochemical capacitor C ₂Negativing ending grounding strobes, moment VC ₂, VC ₃Electric capacity is filled, coupling capacitance C ₃Positive pulse signal ends, and one-way SCR TS control utmost point triggering signal disappears, because resistance R is extremely gone up in controllable silicon TS control ₃Ground connection forces controllable silicon to turn-off, and the fluorescent lamp operate as normal is finished about 1 second kind of said process.

The energy-saving, service life prolonged electronic starter of the utility model has following advantage:

1. energy-saving, service life prolonged, this starter adopts the phase-shift pulse halfwave rectifier to trigger one-way SCR, starting current is two minutes of old starter, operating current on average cuts down the consumption of energy 1～2 watt, and luminance balance has current-limited startup, starting speed is fast, do not have stroboscopic again, do not have characteristics such as impact, fluorescent tube is lengthened the life more than 3 times.

2. suitable power is wide, all types of fluorescent lamps of 4～100W.

3. the minimum 160V of starting voltage, the highest voltage 300V that bears.

Useful life the longest, can reach tens thousand of time more than, the no power consumption of relying on oneself.

5. be not subjected to temperature, the humidity restriction can be used in subzero.
