LED fluorescent lamp
LED made of fluorescent tubes, the appearance of the structure is the same as with traditional fluorescent tubes, fluorescent tube within a solid-state semiconductor light-emitting device, tube selection --- LED light-emitting diode
Characteristics, LED fluorescent tubes
1) environmental traditional fluorescent lamps to protect the Earth contain large amounts of mercury vapor and if broken mercury vapor will evaporate into the atmosphere. The LED fluorescent do not use mercury, and LED products do not contain lead, play a protective effect on the environment. The LED fluorescent recognized green lighting of the twenty-first century.
2), efficient conversion will generate a lot of heat reduce fever traditional lamps, LED lamps are energy all converted to light, and will not cause energy waste. File, the clothing will not fade phenomenon.
3), quiet and comfortable no noise LED lamps do not produce noise, using precision electronic instruments occasions is the good choice. Suitable for a library, offices and the like occasions.
4) the use of eye protection traditional fluorescent light soft AC, so 100-120 times per second strobe. LED lamps directly convert the AC to DC, will not produce flicker, protect your eyes.
5) No UV no mosquito LED lamps will not produce ultraviolet, and therefore will not like traditional lamps, there are a lot of mosquitoes around the light source side. The Indoor become more clean sanitation and clean.
6), voltage adjustable 80V-245V traditional fluorescent lamp is a high voltage rectifier release to light, you can not light up when the voltage decreases. LED lamps can be lit in a certain range of voltage can also adjust the brightness of the light.
7), saving energy and longer life LED fluorescent lamp power consumption is less than one-third of traditional fluorescent, life expectancy is 10 times the traditional fluorescent, long-term use without the need to replace, reduce labor costs. More suitable for occasions that are difficult to replace.
8), robust, secure long-term use LED lamp body is epoxy instead of the traditional glass, more robust, secure LED is also not easily damaged, even hit the floor, you can safely use.
2, the company's production of LED energy-saving lamps have the following characteristics:
1) selection of imported light source, single LED up 5.5LM, special products, the professional design, in full compliance with the general production of the national standard (GB50034-92) illuminance of 100-200 lux (Lux) requirements.
2), the product using the latest semiconductor light source technology, saving up to 80% or more. (10 months to save electricity and maintenance and repair costs enough invested greater than the purchase of the lamp).
3), comply with the strict rules of the factories station on the color rendering index, appeared on a variety of raw materials, components and products color real accurate, favorable product quality control, to reduce the chance of error.
4), the lamp with thermostat control, never fever, the glass envelope, transmittance, no aging. Green semiconductor light source, light and soft, pure spectrum, eyesight protection and good health in favor of workers. 6000K cold light source gives visually cool feeling, plus the difference in illumination design work and non-work interval, helps to concentrate and improve efficiency.
5), 10 times more than ordinary lamp, the lamp life is almost maintenance-free, and there is no lamp, ballast, starter must be frequently changed.
6), voltage range: AC80V-127V, 165V-245V; LED fluorescent lamp without starter and ballast, fast start, small power, no flicker, not easy to cause eye fatigue. Widely used in the garment factory, electronics factory assembly line.
Second, the conventional fluorescent
Fluorescent structure and function: the ends of each filament of fluorescent lamp filled with a trace of argon and thin mercury vapor, is coated with a phosphor on the tube wall, the gas between the two filament conductive emits ultraviolet light, the phosphor issued soft visible.
Fluorescent work characteristics: Lamp ignited requires a high voltage, the small current is allowed only through the normal light, when the voltage across the lamp is less than the supply voltage.
Fluorescent tubes equipped with filament ends, the glass tube wall is coated with a thin uniform layer of phosphors, after the tube has been pumped into the vacuum 10-3-10-4 mmHg charged into a small amount of an inert gas, while also injecting a trace amount of liquid mercury. The inductive ballast is an iron core inductor coil, the nature of the inductor when the current in the coil is changed, the change of the magnetic flux in the coil will cause, thereby generating an induced electromotive force, direction and current of the opposite direction, thereby preventing forward current changes.
Starter switch in the circuit from it by a neon gas discharge tube and a capacitor connected in parallel, the capacitance of the role for the elimination of electromagnetic interference on the power supply and forming an oscillation circuit with the ballast, to increase the start-pulse voltage amplitude. The discharge tube an electrode composition, the use of double metal sheet discharge heating neon bulb, the bimetal in the opened or closed, causing the current mutation of the inductive ballast and generates a high voltage pulse is applied across the lamp.
When the lamp access circuit, began to glow discharge between two electrodes QiHuiQi from bimetal thermal expansion of the pole contactors with quiet touch, so the power supply, ballast, filament and starter form a closed loop, the current so that the filament preheating, when the heating time of 1-3 seconds, the discharge between two electrodes of a glow QiHuiQi extinguished, followed bimetal cooled very disconnected with the stationary contact, when disconnected from the two electrodes of the moment the current in the circuit suddenly disappeared, so ballast generates a high voltage pulse, which superimposed power supply, applied to the tube ends, so that the lamp and the inert gas ionization caused by arc discharge, in the normal light emitting process, the town The self-inductance of the converter also plays the role of the current stabilizing circuit.
