The LED fluorescent tube

 

Appearance of LED and LED fluorescent tube, the same structure with the traditional fluorescent tube, and internal different LED fluorescent tube, tube to choose the semiconductor solid-state light-emitting device - LED light-emitting diodes.

 

LED fluorescent tube advantages: LED fluorescent tube with high quality, durable, energy saving as the main characteristics of the projection point of the adjusting range is big, the brightness of the 15 w is equivalent to ordinary 40 w fluorescent lamp. High temperature resistance, moistureproof and waterproof, prevent leakage. Using voltage: 110 v, 220 v optional, outer garment optional glass or PC material. Lamp holder and common fluorescent lamp.

 

LED fluorescent tube adopts the latest LED light source technology, digital design, the power saving more than 70%, the 12 w LED solar light intensity is equivalent to 40 w fluorescent tube (for the starter and ballast, 36 w fluorescent lamp real power consumption for 42 w to 44 w). LED daylight lamp life for more than 10 times of ordinary lamp, almost maintenance free, often do not need to change the lamp, LED lamps and lanterns of the starter and ballast. Green environmental protection of semiconductor lighting, the light is downy, spectrum pure, is conducive to the user's visual acuity protection and health. 6000 k in the cold light source, give a person the feeling of cool and refreshing on the vision, humanized design illumination differences, more help to concentrate, advances the efficiency. Is a pair of green lighting source.

 

Originally installed the old common fluorescent lamp holder, light tube and starter down first, and then put on a new purchase of LED fluorescent tube, electricity can be used directly, refer to the original LED daylight lamp bracket has two kinds: one, two electronic ballast inductance ballasts.

 

Inductance ballasts can not make any changes, but the electronic ballast will line cut, all the electronic ballast, the zero line and the wire from the two ends of the lamp holder, respectively. Change the LED fluorescent tube advantage is line does not need to make any changes, power consumption is very low, service life is long, there is no special temperature tubes. Thank you very much!

Common fluorescent tube

 

The appearance of normal daylight: thin, long, unlike some of the light bulb, is round.

 

Fluorescent lamp structure and function: each has a filament on both ends of the fluorescent lamp, inside the tubes filled with tiny amounts of argon and weak mercury vapor lamp on the inner wall coated with phosphor, between the two filament gas when conducting an ultraviolet, the fluorescent powder soft light.

 

Characteristics of the fluorescent lamp, lamp began to ignite need a high voltage, normal light only promised by small current, then two whole lamp voltage below the supply voltage.

 

On both ends of the fluorescent tube is equipped with a filament, the glass tube inner surface coated with a thin layer of phosphor, tube is pumped into the vacuum after the 10-3-10-4 mm hg, fill with a small amount of inert gas, at the same time also note into the liquid water trace amounts of silver. Is a core inductance coil inductance ballast, the inductance of the nature is when the current in the coil change, will cause the change of the magnetic flux in coil, thus produce inductive electromotive force, the direction and the current in the opposite direction, thus hindering the current changes.

 

Electric fluorescent starter switch role in the circuit, it consists of a neon tube and a capacitance in parallel, and the role of the capacitor to eliminate the power supply of electromagnetic interference with ballast tank formation, and increase the voltage amplitude of the start pulse. An electrode in the discharge tube with double metal, use neon bulb discharge heating, make the bimetallic strip when open and close, inductance ballast current mutation on both ends of the tube and generate high voltage pulse.

 

After into the circuit when the fluorescent lamp, electric fluorescent starter began to glow discharge between two electrodes, the bimetallic strip heat expansion and contact with the static contact extremely, so the power supply, LED lighting, LED lamp ballasts, filament, and electric fluorescent starter constitute a closed loop current filament preheating, 1-3 seconds when the heating time, electric fluorescent starter of glow discharge between two electrodes, then the bimetallic strip cooling and static contact is extremely disconnected, when two electrodes disconnect instantly, the current in the circuit is suddenly disappear, so the ballast produces a high voltage pulse, it and power superposition, on both ends of the tube and, make the inert gas ionization inside the tube caused by arc discharge, in the process of normal light, ballast self-induction is stable
