Description
Technical field
The utility model relates to a kind of fluorescent lamp, particularly a kind of Novel LED fluorescent lamp.
Background technology
Fluorescent lamp uses for many years in worldwide, replace incandescent, and economize on electricity, light stability are its advantages.But, under the situation of modern global energy anxiety, still belong to the bigger light fixture of power consumption, be not suitable for saving in the present global range requirement of the energy.
Before the present utility model, a kind of LED fluorescent lamp has been arranged, its profile is still according to original fluorescent lamp, but illuminator changes over LED.In order to make the LED can be luminous, must use switch power controller, and switch power controller adopts transformer to convert interchange to direct current, and by oscillating circuit through metal-oxide-semiconductor control LED fluorescent lamp.This switch power controller exists bulky defective, and the same with the ballast of original fluorescent lamp is big, and heavier, separates with fluorescent tube, cooperate one use; Simultaneously, because transformer itself exists cost height, inefficient defective, make the LED fluorescent lamp because cost is too high like this, its application is subjected to very big restriction.
Summary of the invention
This purpose of this utility model just is to overcome above-mentioned defective, designs, develops a kind of Novel LED fluorescent lamp.
The technical solution of the utility model is:
Novel LED fluorescent lamp, the fluorescent tube that rectification circuit, oscillating circuit, metal-oxide-semiconductor is arranged, constitute by LED, rectification circuit output connects oscillating circuit, oscillating circuit output connects metal-oxide-semiconductor, metal-oxide-semiconductor output connects the fluorescent tube that is made of LED, its major technique is characterised in that rectification circuit is also exported and connects inductance that inductance output connects the fluorescent tube that is made of LED.
Further technical scheme of the present utility model is:
Be wound with first inductance coil, second inductance coil on the inductance, the output of first inductance coil connects the fluorescent tube that is made of LED, and the output of second inductance coil connects oscillating circuit.
Further technical scheme of the present utility model is:
The output of second inductance coil connects integrating circuit, and integrating circuit output connects power amplifier, and power amplifier output connects oscillating circuit.
Advantage of the present utility model and the effect power-supply controller of electric volume that is to open the light is little, in light weight, can be directly installed in the fluorescent tube, and also the efficient height, more energy-conservation, power saving.
Other advantage of the present utility model and effect will continue to describe below.
Description of drawings
Fig. 1---structural principle schematic diagram of the present utility model.
The specific embodiment
As shown in Figure 1:
220 volts in alternating current output to first inductance coil 3, oscillating circuit 4 on the inductance 2 respectively, and inductance coil 3 outputs to fluorescent tube 5 through rectification circuit 1 rectification, and oscillating circuit 4 outputs connect metal-oxide-semiconductor 6, and metal-oxide-semiconductor 6 outputs connect fluorescent tube 5; On inductance 2, be wound with inductance coil 7, the second inductance coils 7 in addition and connect integrating circuit 8, power amplifier 9 to oscillating circuit 4.
Duty explanation of the present utility model:
When 220 volts in alternating current after rectification circuit 1 rectification, one tunnel first inductance coil, 3 outputs on inductance 2 connect the fluorescent tube 5 that is made of LED, the fluorescent tube 5 that be made of LED this moment just can be luminous; But, because the instability of voltage causes LED can not give full play to its illumination effect; Therefore, from inductance 2, tell the second other inductance coil 7 again, second inductance coil 7 is through the shaping of integrating circuit 8, and through the amplification of power amplifier 9, output connects oscillating circuit 4 again, the impulse waveform that oscillating circuit 4 is produced is smooth, the frequency of control impuls and width again through MOS circuit 6, are given LED stable impulse waveform all the time, thereby make the LED can be luminous consistently, make the whole fluorescent tube 5 that constitutes by LED shinny.
Because rectification circuit 1, inductance 2 comprise first inductance coil 3, second inductance coil 7 on it, oscillating circuit 4,, metal-oxide-semiconductor 6, integrating circuit 8, power amplifier 9 constitute one, form a complete power supply switch controller, concrete little, the lightweight advantage of volume, therefore it can be directly installed in the fluorescent tube 5 that constitutes by LED, usually can install or be placed on the back side of LED installing plate, form one.
Hence one can see that, the utility model is combined into inseparable integral body with power supply switch controller and fluorescent tube, certainly will bring advantage easy for installation,, must not consider again which power supply switch controller is installed in as long as the contact of fluorescent tube two ends is inserted in the lamp base.
