Abstract
The utility model discloses a start circuit used for the energy-saving lamp, comprising a current stabilizer and a thermistor. The thermistor is connected with the current stabilizer of which the output end is connected to the fluorescent tube stem with the amalgam. The thermistor adopts the ring structure and directly fits over the fluorescent tube stem. Also, the thermistor is deemed as the PTC thermistor on the resonant capacitance of the current stabilizer or the NTC thermistor which forms the series connection with the lamp filament. The start circuit can be used to increase the luminance flux time of the amalgam fluorescent tube.
Description
Affiliated technical field
The utility model belongs to lighting field, particularly relates to a kind of start-up circuit that is applied on the energy-conservation lamp.
Background technology
Electricity-saving lamp is widely used owing to saves energy and long service life.In order to improve the switch number of times and the useful life of fluorescent tube, PTC or NTC thermistor on the start-up circuit of electricity-saving lamp, have all been used with special resistance characteristic.General PTC thermistor is connected in parallel on the resonant capacitance of ballast, the NTC thermistor is connected on the filament, electric current is flowed through PTC or NTC thermistor earlier to filament pre-heating when starting, PTC or NTC thermistor heating in warm, (this moment, the PTC thermistor was in approximate open-circuit condition to anxious poly-rising of temperature, the NTC thermistor is in approximate short-circuit condition), just lamp is lighted afterwards by high-frequency resonant, reach the switch number of times of raising fluorescent tube and the purpose in useful life.
But the structure of applied PTC thermistor or NTC thermistor all is a cylindrical structural on the existing electricity-saving lamp start-up circuit, the usage of existing this PTC or NTC thermistor only limits to reach the switch number of times of raising fluorescent tube and the purpose in useful life, there is no to reach the function that improves the band amalgam fluorescent tube logical rise time of light.
Summary of the invention
The purpose of this utility model provides the electricity-saving lamp start-up circuit of a kind of raising to the band amalgam fluorescent tube logical rise time of light at the logical slow partially problem of rise time of above-mentioned amalgam fluorescent tube light.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of start-up circuit of electricity-saving lamp, comprise ballast, thermistor, thermistor is connected on the ballast, ballast output end is connected with the lamp tube core column that has amalgam, thermistor structure is a loop configuration, and it directly is enclosed within on the lamp tube core column.
Thermistor described in the utility model is the ring-shaped P TC thermistor that is connected in parallel on the resonant capacitance of ballast.
Thermistor described in the utility model is the annular NTC thermistor that is connected on the tube filament.
The start-up circuit of a kind of electricity-saving lamp of the utility model owing to adopted the PTC or the NTC thermistor of loop configuration, improves the band amalgam fluorescent tube logical rise time of light; The PTC of loop configuration or NTC thermistor directly are enclosed within lamp tube core column, and to upload heat conduction amount fast; Can effectively suppress impulse current by preheating to filament; Improve the switch number of times of fluorescent tube and the purpose in useful life; The hurried rising of the own heating temp of ring-shaped P TC thermistor during startup, conduction also conducts heat in the amalgam in the stem stem for the stem stem of its bag that encircles indirectly, quickening the amalgam temperature rises, improved the rise time of whole lamp, reached the required time of 80% initial lumen, solved slow partially (＞120S) problem of amalgam fluorescent tube rise time; Annular NTC thermistor is connected on the filament during startup, NTC is in approximate short-circuit condition, anxious poly-rising of temperature, conduction also conducts heat in the amalgam in the stem stem for the stem stem of its bag that encircles indirectly, quickening the amalgam temperature rises, improved the rise time of whole lamp, reached the required time of 80% initial lumen, solved slow partially (＞120S) problem of amalgam fluorescent tube rise time;

Embodiment
One, embodiment one
In conjunction with Fig. 1, Fig. 4 the start-up circuit of a kind of electricity-saving lamp of the utility model is described further.PTC thermistor 1 is connected in parallel on the resonant capacitance 3 of electric ballast 2.Fluorescent tube 4 stem stems that have amalgam are connected in parallel in the two ends of electric ballast 2 outputs.PTC thermistor 1 is a loop configuration, directly is enclosed within on fluorescent tube 4 stem stems that have amalgam.Power supply U obtains direct voltage stably after the rectification of electric ballast 2, filtering.The resonant capacitance 3 of electric ballast 2 outputs and the preheat circuit that is connected in parallel on the PTC thermistor 1 composition filament on the electric capacity 3.
The electric current that electric ballast 2 the flows out during startup 1 pair of filament pre-heating of PTC thermistor of flowing through earlier, in the warm to filament, the resistance of PTC thermistor 1 is because being heated of self and hurried increasing is in approximate open-circuit condition.PTC thermistor 1 is own owing to the hurried increasing of resistance simultaneously, the also hurried rising of heating temp.The temperature conduction of PTC thermistor 1 is given fluorescent tube 4 stem stems of its bag that encircles and is conducted heat to indirectly in the amalgam in the stem stem, rises thereby quicken the amalgam temperature, improves the rise time of putting in order lamp.
Two, embodiment two
The start-up circuit of a kind of electricity-saving lamp of the utility model, embodiment two as shown in Figure 2.Embodiment two is with embodiment one difference: the resonant capacitance 3 of electric ballast 2 comprises the electric capacity 31 and the electric capacity 32 of connecting; The PTC thermistor 1 of loop configuration is connected in parallel on the electric capacity 31; The resonant capacitance 3 of electric ballast 2 outputs and the preheat circuit that is connected in parallel on the PTC thermistor 1 composition filament on the electric capacity 31.
Three, embodiment three
The start-up circuit of a kind of electricity-saving lamp of the utility model, embodiment two as shown in Figure 3.Embodiment three is with embodiment one difference: NTC thermistor 1 is connected on the fluorescent tube 4; NTC thermistor 1 is a loop configuration, directly is enclosed within on fluorescent tube 4 stem stems that have amalgam; The resonant capacitance 3 of electric ballast 2 outputs and the preheat circuit that is connected on the NTC thermistor 1 composition filament on the fluorescent tube 4.
The electric current that electric ballast the flows out during startup 1 pair of filament pre-heating of NTC thermistor of flowing through earlier, in the warm to filament, NTC thermistor 1 resistance is because the heat that self produces and hurried minimizing is in approximate short-circuit condition.The temperature conduction of NTC thermistor 1 is given fluorescent tube 4 stem stems of its bag that encircles and is conducted heat to indirectly in the amalgam in the stem stem, rises thereby quicken the amalgam temperature, improves the rise time of putting in order lamp.
