Pure light emitting diode (LED) daylight lamp tube capable of directly replacing fluorescent lamp tube

Abstract

The invention discloses a pure light emitting diode (LED) daylight lamp tube capable of directly replacing a fluorescent lamp tube. The pure LED daylight lamp tube consists of a lamp housing, lamp heads, an LED circuit board and a pure LED light emitting module, wherein the lamp heads are arranged at two ends of the lamp housing, and the pure LED light emitting module basically conforms to the capacitive reactance and the resistance reactance of the fluorescent lamp tube to be replaced. The addition of active or passive devices is not needed, the LED daylight lamp tube capable of realizing the independent replacement and the independent work is really obtained, the fluorescent lamp tube can be directly replaced, the pure LED daylight lamp tube is directly used on a fluorescent lamp tube lamp, the modification on the lamp is not needed, the LED daylight lamp tube can be conveniently and effectively replaced, the installing cost is saved, the economic benefits are improved, the light emitting efficiency of an LED daylight lamp can be further improved, and the work service life of the LED daylight lamp can be further prolonged. Compared with the ordinary fluorescent lamp tube and LED daylight lamp tubes, the pure LED daylight lamp tube has the advantages that more energy is saved, and a great effect is realized on promoting the LED light source popularization.

Description

technical field [0001] The invention relates to an LED fluorescent lamp tube, in particular to a pure LED fluorescent lamp tube which can directly replace the fluorescent lamp tube. Background technique [0002] At present, LED has the advantages of low power consumption, environmental protection, no pollution, energy saving, etc. With the continuous development of LED technology, old fluorescent tubes are gradually eliminated, and more and more users use LED fluorescent tubes to replace old fluorescent lamps, but due to At present, most fluorescent tubes use electronic ballasts to drive fluorescent tubes. Generally, the structure of LED fluorescent tubes is very different from that of old fluorescent lamps, and they cannot work directly on electronic ballasts. Therefore, LED fluorescent tubes cannot be directly installed on old fluorescent lamps. Tube lamps, if you need to replace the LED fluorescent tubes, you need to replace the lamps or modify the original lamps, which b...

[0002] At present, LED has the advantages of low power consumption, environmental protection, no pollution, energy saving, etc. With the continuous development of LED technology, old fluorescent tubes are gradually eliminated, and more and more users use LED fluorescent tubes to replace old fluorescent lamps, but due to At present, most fluorescent tubes use electronic ballasts to drive fluorescent tubes. Generally, the structure of LED fluorescent tubes is very different from that of old fluorescent lamps, and they cannot work directly on electronic ballasts. Therefore, LED fluorescent tubes cannot be directly installed on old fluorescent lamps. Tube lamps, if you need to replace the LED fluorescent tubes, you need to replace the lamps or modify the original lamps, which brings great inconvenience to users when replacing LED fluorescent tubes. Hiring professional personnel for replacement greatly increases the cost of replacement, and at the same time brings great obstacles to the promotion of environmentally friendly and energy-saving LED fluorescent tubes

[0003] At present, there are also LED fluorescent tubes that can be used directly on fluorescent tube lamps, but based on the working mode of electronic ballasts, especially electronic ballasts with various protection circuits, if the external load is too different from the design parameters, The electronic ballast will automatically protect and stop working, or the electronic ballast will not work in the normal state, thus accelerating the damage of the electronic ballast, so the LED fluorescent tubes used directly on the fluorescent tube lamps will be outside the tube Or set an additional rectifier or power module at both ends of the lamp head to convert the high-frequency AC voltage output by the electronic ballast into a suitable working voltage for the LED fluorescent tube to ensure the normal operation of the LED fluorescent tube, but these methods are not real. In the sense of fluorescent tubes that can work independently, the attached rectifier or power module not only increases the cost and weight of the LED fluorescent lamp, but also has a large loss in the rectifier or power module, which does not really reflect the energy saving and environmental protection of the LED fluorescent lamp
