Fluorescent lamp direct sales share the origin of fluorescent lamp

&Fluorescent lamp is also called fluorescent lamp. It uses low-pressure mercury vapor to release ultraviolet light after being electrified to make the fluorescent powder emit visible light. Therefore, it belongs to low-pressure arc discharge light source. In 1974, we first developed a fluorescent powder which can emit red, green and blue light sensitive to human eyes. The development and application of this phosphor is an important milestone. The electrodeless fluorescent lamp is the electrodeless lamp. It cancels the filament and electrode of the traditional fluorescent lamp, and uses the principle of electromagnetic coupling to excite the mercury atom from the original state to the excited state. The principle of direct lighting of the fluorescent lamp is similar to that of the traditional fluorescent lamp, with the advantages of long life, high light efficiency and good color rendering.

&The size of LED fluorescent tube also depends on the size, for example: φ 26mm * 600mm, the size is: length 600mm, diameter 26mm. Usually, the light emitted is softer and accepted by people. In the specification of fluorescent tube, T10 tube diameter (10 / 8) × 25.4 = 31.8mm; T8 tube diameter (8 / 8) × 25.4 = 25.4mm; T5 tube diameter (5 / 8) × 25.4 = 16mm. Different types of fluorescent tubes have different specifications.

&The maintenance method of fluorescent lamp

&Nbsp; & nbsp; the fluorescent lamp cannot be turned on and off frequently, which may cause the two ends of the lamp to turn black and affect the output power of the lamp. It is also necessary to note that the lamp will be restarted after turning off the lamp, generally waiting for 5 to 15 minutes. If the voltage is low, the two poles of the lamp will emit at the beginning of lighting, which will cause a lot of pollutants inside the lamp, which is one of the reasons for the damage of the lamp. Therefore, it is suggested that the lamp can be turned on only under the condition of high voltage as far as possible to ensure that the lamp tube has suitable power.

    direct fluorescent lamps should keep ventilation environment, take away dust, perpetual lamp tube temperature and prolong lamp life. Because the fluorescent lamp is hot and easy to attract dust, when cleaning, turn off the power supply, wring out the rag, gently wipe the lamp tube, and try to keep indoor air circulation. If possible, use an anti-static duster, which can be used to clean the dust of the lamp tube, and then use a dry rag to wipe. Do not use too much force.
