Description
Technical field
The utility model relates to a kind of fluorescent lamp, particularly a kind of LED fluorescent lamp that can stepless dimming.
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, the luminosity of fluorescent lamp can not be regulated.The new LED fluorescent lamp is because to adopt transformer be the main mode of Switching Power Supply control device, makes the LED fluorescent lamp can't accomplish that also luminosity can regulate.And luminosity can be regulated and is to use the people to reach as the case may be both to have guaranteed brightness to do to want the thing of doing, a kind of requirement that can save electricity again.
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:
LED fluorescent lamp that can stepless dimming, rectification circuit is arranged, oscillating circuit, metal-oxide-semiconductor, the fluorescent tube that constitutes 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, rectification circuit is also exported and is connect inductance, be wound with first inductance coil on the inductance, second inductance coil, the output of first inductance coil connects the fluorescent tube that is made of LED, the output of second inductance coil connects integrating circuit, and integrating circuit output connects power amplifier, and power amplifier output connects oscillating circuit, its major technique is characterised in that at power amplifier increases an input, and this input connects an adjustable potentiometer.
Advantage of the present utility model and effect are can the step-less adjustment luminosity, to adapt to electricity consumption place and situation, to reach 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; In power amplifier 9, increase an input again, but this input connects the potentiometer 10 that a continuously smooth is regulated resistance sizes.
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.
Potentiometer 10 in the increase of power amplifier 9 inputs, size by regulator potentiometer 10, make the size of the output of power amplifier 9, make oscillating circuit 4 inputs constantly be changed the signal of size, the impulse waveform of its output also and then changes size, exports metal-oxide-semiconductor 6 to, metal-oxide-semiconductor 6 exports fluorescent tube 5 to, make LED in it constantly be changed the signal of size, LED luminous will be from bright to weak until not working fully, or brighten up to the brightest gradually from not working.
By the utility model, make fluorescent lamp can carry out stepless dimming for the first time.
