    The advantages and characteristics of LED fluorescent lamp

    A, the common fluorescent lamp

    Fluorescent lamp structure and function: fluorescent lamp at each end a filament, tubes filled with traces of argon within and the thin mercury vapor lamp on the wall is phosphor coating, two filament of the gas between a conductive ultraviolet ray, make a soft light. The phosphor

    Fluorescent lamp working characteristics: tubes start up need a high voltage, normal light at the current is allowed only through, then tubes on both ends of the voltage is lower than the power supply voltage.

    Fluorescent tubes with the filament glass tube ends, coated with a layer of inner uniform thin phosphor, tube being pumped into the vacuum degree-4 10-3-10 millimeters of mercury, filling a few after inert gas, and also into the trace of liquid water on the silver. Ballast is a core inductance coil, the nature of the inductance coil is when the current changes in coil, then will cause the magnetic flux of variety, thus produce induction emf, its direction and current in opposite directions, thus the hindering current changes.

    QiHuiQi in a circuit switch function, it up by a NaiQi discharge tube and a capacitance parallel and become, the role of capacitance for elimination of power supply of electromagnetic interference and with ballast form oscillation loop circuits, start pulse voltage amplitude increase. Discharge tube a electrode with a metal composition, NaiPao discharge of heat, the dual metallic piece in the open and close, cause inductance ballasts current mutations and produce high pressure pulse added to the tube at both ends.

    When fluorescent lamp access circuit, QiHuiQi after two electrodes began to glow discharge between, make double metal expands when it is heated and static contact with a contact, and power supply, ballast, filament and QiHuiQi makes a close loop, current make filament preheating, when heating time 1-3 seconds later, QiHuiQi two between electrodes glow discharge, then put out optic-fiber cooling and static contact with a disconnect, when two electrodes disconnect moment, the current in the circuit suddenly disappeared, and produce a high pressure pulse ballast, it and the power source stacked and added it to the lamp, make both ends in the tube inert gas ionization and cause arc discharge, in normal light process, ballast self-induction is also plays the role of the current in the circuit stability.

     

    Second, the LED fluorescent lamp

    LED the is made of a fluorescent tubes, appearance with the traditional structure of fluorescent tubes is same, and the inside the sun is different, choose the semiconductor solid tube light devices-LED light emitting diode

    1, LED the characteristics of fluorescent lamp

    1), environmental protection lamps and lanterns, and protecting the earth traditional fluorescent lamp contains a lot of mercury vapor, if broken mercury steam will evaporate into the atmosphere. But the LED fluorescent lamp is don't use mercury, and LED products also don't lead to the environment protection. The LED fluorescent lamp recognized for the 21 st century green lighting.

    2), efficient conversion, reduce heat traditional lamps and lanterns will produce large amounts of heat energy, and LED lamps and lanterns is all the electrical energy into light energy conversion, won't cause a waste of energy. And to a file, clothing to also won't produce fading.

    3), quiet and comfortable, there is no noise LED lamps and lanterns will not produce noise, to the use of the instrument for precision electronic occasion beautiful anthology. Suitable for library, the office of such occasion.

    4), the light is downy, protection of the traditional fluorescent lamp use eyes is alternating current, so every second will produce 100 to 120 times the bandwidth of flash. The LED lamps and lanterns is directly convert alternating current to direct current, won't produce flashing phenomenon, protect eyes.

    5), no ultraviolet ray, no mosquito LED lamps and lanterns will not produce ultraviolet light, so it won't like traditional lamps and lanterns that, there are many mosquito around in the light source. Indoor will become more clean sanitation clean and tidy.

    6), voltage can be adjusted 80 V-245 V traditional fluorescent lamp is through the rectifier of release of the high voltage to the light, when the voltage is not low light. And LED lamps and lanterns in a range of voltage within the light, still can adjust to brightness.

    7), save energy, longer life LED the power consumption is the traditional fluorescent lamp under a third of the fluorescent lamp, life is traditional fluorescent lamp of 10 times, can use for a long time without replacement, reduce labor cost. The more suitable for the occasion of hard to replace.

    8), the firm firm, use for a long time. LED lamp body itself is using epoxy resin and not the traditional glass, the more the firm firm, even if hit on the floor also won't easily damaged LED, can safely use.

    2, the company produced LED the energy-saving fluorecent tubes has the following features:

    1), USES imported light source, single LED up to 5.5 LM, special products, professional design, fully comply with national standards GB50034 general production (92) 100-200-lux Lux (Lux) requirements.

    2), this product USES the latest semiconductor electric light source technology, save electricity is as high as 80% above. (10 months to save electricity and related the maintenance and repair costs more than the purchase of the tube foot into).

    3) and comply with the factory points to the colour developing index strict rules on the various raw materials, components and the product itself color accurate appears, the product quality control, reduce the favorable the chance of error.

    4), provided by temperature control, never fever, the glass cover, completely the strong, without aging. The green environmental protection semiconductor electric light source, the light is downy, the spectrum pure, be helpful for workers and healthy eye protection. 6000 K of cold light to person visual sense of cool and refreshing feeling, plus and supervise the work of the intensity of illumination differences on the interval design, and it is helpful to concentrate, improve efficiency.

    5), the lamp life for ordinary lamp of 10 times above, is almost free maintenance, there are often should change fluorescent tubes, ballast, and the problem of the hui.

    6), voltage range: AC80V-127 V, 165 V-245 V; Without QiHuiQi and LED fluorescent lamp ballast and start fast, small, no flash power frequency, not easy to cause vision fatigue. Widely used in enterprise, enterprise, etc. Various kinds of water production line.

    Three, incandescent lamp, fluorescent lamp, common LED, high power LED fluorescent lamp service life contrast
