Abstract
The utility model relates to a capacitance type electronic rectifier. Connection and disconnection of the rectifier D<3> are controlled by the relay J which is connected in series between a capacitor C1 and a strip lamp, which achieves the automatic switchover between dual voltage starting procedure and ballasting procedure and brings convenience to installation and use of the utility model for users.
Description
The utility model relates to a kind of circuit control device, belongs to the daylight electronic lamp ballast.
Usually used fluorescent lamp is finished starter, ballast by Inductive ballast, starter, and sort circuit can not be realized low-voltage starter, and inductive loop consumes active power simultaneously, is unfavorable for energy-conservation.
In order to address this problem, existing invention is to form the voltage multiplying rectifier starter with electric capacity and rectifying tube, Chinese patent (application number 88202543.0) discloses such invention, and it uses an electric capacity and a rectifying tube to form half-wave rectifier, and fluorescent tube is connected on the two ends of rectifying tube, fluorescent tube just can obtain its required conducting voltage like this, make its moment open-minded, at this moment, use a manual switch again, disconnection of rectifying tube that will be in parallel with fluorescent tube, fluorescent tube just can be normally luminous.But the sort circuit structure when turning on the power switch, also needs pressing hand switch again owing to adopt hand switch, the participation that this will ask for help, and inconvenience is used, and is difficult to make starter, ballast process to reach best transition.
The purpose of this utility model provides a kind of improved fluorescent lamp starter, and it adopts relay to control the automatic switchover that realizes multiplication of voltage starter and ballast process.
The purpose of this utility model is achieved in that direct current relay of serial connection between the electric capacity of capacitance voltage-multiplying rectification circuit and fluorescent tube, it is what to control by a normally-closed contact of this relay that rectifying tube connects disconnected in circuit, when the tube starting conducting, current flowing is arranged in the relay coil, the actuating of relay, its normally-closed contact disconnects, thereby cuts off the rectifying tube that is connected in the loop.
Accompanying drawing is an electrical schematic diagram of the present utility model
Further narrate the course of work of the present utility model below in conjunction with accompanying drawing:
K is mains switch, D among the figure
1, D
2, D
3For rectifier diode, J are a direct current relay, K
1A pair of normally-closed contact for relay J.
The energized K switch, at this moment, fluorescent tube ends, and the power-half cycle is through tube filament 1 → D
3→ K
1→ filament 2 → D
1Give capacitor C
1Charging, the positive half cycle of power supply, D
3By C
1On voltage and the positive half cycle voltage of electrical network through D
2, J is superimposed on lamp tube ends, when superimposed voltage reached certain value, promptly lamp tube ends voltage reached and makes the fluorescent tube arc discharge, just there are current flowing, the actuating of relay in the fluorescent tube loop.Its normally-closed contact K
1Disconnect, so just finished D
3From the purpose that fluorescent tube disconnects, D
1, D
2, C
2, R plays a part to guarantee relay J steady operation, C not influencing under the circuit normal operation
1After the fluorescent tube conducting, play the effect of step-down ballast.
The utility model is owing to adopt relay to replace hand switch, and the best that has reached starter and ballast process automaticallyes switch, and convenient for users to use and installation.
Claims (1)
- A kind of fluorescent lamp condenser type electric ballast is made up of voltage doubling rectifing circuit and relay, it is characterized in that: in the capacitor C of voltage doubling rectifing circuit 1And between the fluorescent tube also series connection be connected to a relay J, the company of rectifying tube D3 is disconnected to be normally-closed contact K by this relay 1Control.
