Abstract

The utility model belongs to a lamp which is composed of a lamp, a lampshade, and an electronic ballast which is fixed on the lampshade, etc. A capacitor, a resistor, an electromagnetic coil, a normally closed switch, and a diode are sealed and arranged in the electronic ballast, wherein, the capacitor is connected in series with the resistor, the lamp, the electromagnetic coil, and a switch for a power supply, the connecting point of the capacitor and the resistor is connected with the negative end of the diode, the positive end of the diode is connected in series with the normally closed switch, and the other end of the normally closed switch is connected with the connection point of the switch of the power supply and the electromagnetic coil. The utility model has the advantages of low starting voltage, simple circuit, small accessory size and low cost. Because the circuit connection mode of a fluorescent lamp is altered, even when filament breakage occurs, the fluorescent lamp can be successively used, and the service life of the fluorescent lamp is extended.

Description

Novel fluorescent lamp

The utility model belongs to a kind of lamp, relates to a kind of fluorescent lamp.

Fluorescent lamp is a kind of energy converter, and it comprises fluorescent tube and annex thereof.Fluorescent tube is by filament, and lamp holder and glass are formed from pipe, and annex is made up of lampshade and the ballast that has a starter.Because the every startup of fluorescent lamp once, will be subjected to the impact of pulsatile once high potential between two negative electrodes, the consumption of electronic emitting material on the filament has been quickened in this impact, and after electronic emitting material on the filament ran out gradually, promptly come to an end the useful life of fluorescent tube.And filament one is disconnected, and whole fluorescent tube just can not re-use.So the useful life of this fluorescent tube is very short, very easily damage.In addition, have and open the ballast circuit complexity of waving device, production cost height, manufacturing process complexity.

The purpose of this utility model is a kind of novel fluorescent lamp of design, and it can reduce the production cost of fluorescent lamp, improves its useful life.

The purpose of this utility model realizes by following scheme: novel fluorescent lamp is by fluorescent tube, lampshade and be fixed on electric ballast on the lampshade etc. and form.Electric ballast is a box body, be packaged with electric capacity, resistance, solenoid, normally closed switch, diode etc. in it, its circuit connects as follows: described electric capacity and resistance, fluorescent tube, solenoid, mains switch are connected in series, electric capacity and resistance joint are connected with the diode negative terminal, its anode is serially connected with normally closed switch, and the other end of normally closed switch is connected the connection of mains switch and solenoid.

This novel fluorescent start voltage is low, only needs to use resistance, electric capacity and a diode, just can make daylight lamp glow starting, so circuit is simple, required element is few, and the annex volume can be done very for a short time, be easy to make and install, and cost is low, and price is easy.In addition owing to the mode of connection that has changed daylight lamp circuit, even the filament generation fracture of wire at fluorescent lamp two ends still can continue to use, so prolonged the useful life of fluorescent lamp greatly.

Fig. 1 is a shape schematic diagram of the present utility model;

Fig. 2 is the shape schematic diagram of ballast in the utility model;

Fig. 3 is the organigram of miniature automatic switch in the utility model;

Fig. 4 is a circuit connection diagram of the present utility model;

Be described as follows below in conjunction with drawings and the specific embodiments:

In Fig. 1, novel fluorescent lamp is made up of fluorescent tube 1, lampshade 2 and the electric ballast 3 that is fixed on the lampshade thereof.

In Fig. 2, electric ballast 3 is a box body, is packaged with the microswitch that electric capacity, resistance, diode and solenoid and normally closed switch are formed in it, on the end face of box body 1, leaves wire hole 4, and ballast output lead 5 is arranged in the hole.

In Fig. 3, the microswitch bag expands solenoid 6 and normally closed switch 7, and solenoid 6 is formed by the heavy gauge wire coiling, has iron core in the coil.Solenoid is fixed on the support 8.Support 8 tops are equipped with a spring leaf 9, and this spring leaf and normally closed switch 7 are connected, and normally closed switch 7 is two closings of contact under the elastic force effect of spring leaf 9.

In Fig. 4, electric capacity 10 is tied mutually with resistance 11, fluorescent tube 12, solenoid 6, mains switch 13 polyphones, electric capacity 10 is connected to diode 14 negative terminals with resistance 11 connections, its anode is serially connected with normally closed switch 7, and the other end of normally closed switch is attached at the connection of mains switch 13 and solenoid 6.

Its operation principle is as follows: fluorescent lamp needs a high voltage when starting, and during operation, only needs a low voltage.When the mains switch 13 of novel fluorescent lamp is closed, fluorescent tube 12 is cold, electric current frequent make and break pass 7 and diode 14 are to electric capacity 10 chargings, when the reverse voltage of power supply arrives, capacitance voltage adds that supply voltage forms a high voltage, this high voltage is added in the two ends of fluorescent tube 12 through resistance 11, and fluorescent tube 12 rapidly electric discharge phenomena takes place and luminous under this high-tension effect.At this moment fluorescent tube 12 conductings, electric current make solenoid produce magnetic field, thereby attract the armature under the spring leaf 9 through solenoid 8, normally closed switch 7 are disconnected, in order to avoid diode influences the operate as normal of fluorescent tube.

When mains switch 13 disconnected, entire circuit did not all have electric current, and solenoid does not pass through because of there being electric current, loses magnetic field, and normally closed switch 7 makes two closings of contact of normally closed switch 7 under the elastic force effect of spring leaf 9, created conditions for starting next time.
