Abstract
The utility model discloses a self-ballasting fluorescent lamp. The utility model comprises a casing 1 whose inner chamber is divided into two closed cavities by a barrier wall 2; two lamp bases 3 and 4 which are respectively arranged on the both ends of the casing 1; a tungsten filament 5 which is arranged in the closed cavity between the lamp base 3 and the barrier wall 2; the electrode of the lamp base 3 which is connected with the tungsten filament 5; two groups of fluorescent lamp filaments 6 and 7 which are arranged in the closed cavity between the lamp base 4 and the barrier wall 2, wherein, the fluorescent lamp filament 7 is connected with the lamp base 4; the fluorescent lamp filament 6 is connected with the other end of the tungsten filament 5 via the barrier wall 2. The utility model which can be matched with the electronic starter of the Chinese patent 94102486.5 by one or two connected in series, has the advantages that the line power factor is near to 1; the energy can be saved; the cost can be reduced; 50Hz stroboscopic phenomenon can not occur.
Description
The utility model relates to the electric lighting device, is specifically related to a kind of self-ballasted fluorescent lamp that incandescent lamp and fluorescent lamp are combined.
Existing fluorescent lamp must use the Inductive ballast of massiveness, has both had the deficiency that power factor is not high, cost is higher, also brings many inconvenience to installation and maintenance.
The purpose of this utility model is to provide a kind of self-ballasted fluorescent lamp with incandescent filament replacement Inductive ballast, and this self-ballasted fluorescent lamp can cooperate Chinese invention patent 94102486.5 described electronic starters, realizes higher power factor and stable performance.
The purpose of this utility model is to realize like this, constructing a kind of self-ballasted fluorescent lamp comprises: the centre have an interlayer 2 with inner chamber be divided into the housing 1 of two enclosure portion, respectively be located at described housing 1 two ends two lamp bases 3 and 4, be located in the cavity between described lamp base 3 and the described interlayer 2 and tungsten filament 5 that an end is connected with described lamp base 3 is arranged, be located between described lamp base 4 and the described interlayer 2 the two groups of fluorescent wires 6 and 7 in the cavity, described filament 7 is connected with described lamp base 4, and described filament 6 is connected with the other end of described tungsten filament 5 by described interlayer 2.
Self-ballasted fluorescent lamp of the present utility model can be single with Chinese patent 94102486.5 in the electronic starter that provides be used, also can two be connected in series again and above-mentioned electronic starter is used, can obviously improve the power factor of power circuit, saves energy, improve the light source performance, reduce cost, and do not have 50HZ and dodge phenomenon frequently.
In conjunction with the accompanying drawings and embodiments, further specify feature of the present utility model and effect.
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is a self-ballasted fluorescent lamp of the present utility model circuit connection diagram when using.
As shown in Figure 1, the tungsten filament 5 in the self-ballasted fluorescent lamp of the present utility model is connected with Filament of fluorescent lamp 6, thereby fluorescent lamp is had metering function.When the electronic starter in it and the aforementioned patent of invention is used, with reference to figure 2, its operation principle is such: after the input energized of electronic starter, pass through the lamp base 3 and 4 of self-ballasted fluorescent lamp of the present utility model from the high direct voltage of its output output, high voltage electric field in the housing can be lured filament 6 and 7 electron-emissive materials in the fluorescent tube, excite mercury vapour ionization conducting in the pipe, make lamp luminescence.When electric current process tungsten filament 5, the electric current in the fluorescent tube is subjected to suitable restriction, and at this moment, tungsten filament is also emitted thermal radiation light, so self-ballasted fluorescent lamp of the present utility model can be at stabilized illumination under the rated power.
Self-ballasted fluorescent lamp of the present utility model adopts tungsten filament 5 this pure resistance elements to make current limliting, does not also have inductance element in the aforesaid electronic starter internal wiring, so its illuminating line power factor just can reach near 1, this result is experiment confirm.Even when the power supply landing was big, fluorescent tube also can obtain more stable power.
Self-ballasted fluorescent lamp of the present utility model is except can be as shown in Figure 2, and an electronic starter connects outside the self-ballasted fluorescent lamp pipe of the present utility model, can also connect two self-ballasted fluorescent lamp pipes of the present utility model that are connected in series by an electronic starter.
The profile of self-ballasted fluorescent lamp of the present utility model can be made different shape, as annular etc.
