Abstract
The utility model relates to a starter for a fluorescent lamp, which belongs to the technical field of illumination. The utility model is composed of a casing, a capacitor, a resistor, and a bidirectional trigger diode of a bidirectional controlled silicon. The utility model is mainly characterized in that the capacitor and the phase difference of the ballast inductance of the fluorescent lamp circuit in the AC circuit, dividing voltages which are larger than the breakdown voltage of the fluorescent lamp are generated at both ends of the capacitor, and thus the fluorescent lamp is switched on, and emits light, the start time is short, the fluorescent lamp can work under the condition of low power supply voltage, the service life of the fluorescent lamp is extended, and the utility model is an ideal replacer of the existing starters.
Description
The utility model relates to a kind of electronic fluorescent lamp starter of lighting field.
In the daylight lamp circuit that uses ballast, also must use starter at present, it is formed in parallel by neon bulb and papery electric capacity, at the lower situation of supply voltage, normally starter.The easy breakdown short circuit of papery capacitive insulation layer in addition, so this starter exists the starting time long, the life-span is short, supply voltage is required high deficiency, and influence the useful life of fluorescent lamp.
The purpose of this utility model is at above-mentioned deficiency, provides a kind of start-up time short, and the electronic fluorescent lamp starter in light modulation useful life extended day greatly.
The purpose of this utility model is achieved through the following technical solutions, a kind of electronic fluorescent lamp starter that comprises housing, the start-up circuit that it is characterized in that electric capacity is arranged in the housing, resistance, bidirectional triode thyristor and bidirectional trigger diode constitutes, electric capacity is connected with bidirectional triode thyristor, resistance is connected with bidirectional trigger diode, another utmost point of bidirectional trigger diode connects with the control utmost point of bidirectional triode thyristor, on the binding post of another utmost point difference body contact body of the common point of resistance and electric capacity and bidirectional triode thyristor.
The utility model in use, make the bidirectional trigger diode conducting and make the bidirectional triode thyristor triggering passage through the resistance step-down, electric capacity forms in daylight lamp circuit with ballast and connects, utilize the phase difference of ballast inductor in alternating current circuit in electric capacity, the daylight lamp circuit, make the electric capacity two ends produce branch pressure voltage, the breakdown voltage value that branch pressure voltage is worked energetically fluorescent tube makes the fluorescent lamp conducting luminous.The utility model is simple in structure, and working stability is reliable, is the existing desirable renewal product of starter, can be widely used in fluorescent lamp (use ballast) circuit.
Accompanying drawing is the utility model start-up circuit electrical schematic diagram.
In the accompanying drawing: capacitor C, resistance R, D1 is a bidirectional triode thyristor, D2 is a bidirectional trigger diode.
Further specifying the utility model in conjunction with the accompanying drawings and embodiments will, capacitor C and bidirectional triode thyristor D1 series connection, resistance R is connected with bidirectional trigger diode D2, another utmost point of bidirectional trigger diode D2 connects the control utmost point of bidirectional triode thyristor D1, and the common point of resistance R and capacitor C connects with the binding post of housing respectively with another utmost point of bidirectional triode thyristor D1.The withstand voltage of capacitor C, resistance R, bidirectional triode thyristor D1 and bidirectional trigger diode D2 should be greater than the puncture voltage of fluorescent tube, the operating voltage of a little higher than fluorescent lamp of minimum conducting voltage of bidirectional triode thyristor D1.
