Single-end LED straight tube fluorescent lamp

Abstract

The invention relates to a single-end LED straight tube fluorescent lamp which comprises an LED illuminator and a lamp tube, wherein a fluorescent powder coating is coated on the inner wall of the lamp tube, one end of the lamp tube is opened and the other end of the lamp tube is closed, and the LED illuminator is arranged at the opening end of the lamp tube. The peak wavelength of a light spectrum of light emitted by the LED illuminator is 320-480nm. Because the LED illuminator capable of emitting blue violet light is arranged at the opening end of the light tube, the peak wavelength of the light spectrum of the LED illuminator is 320-480nm, and the fluorescent powder coating is arranged on the inner wall of the lamp tube, when the blue violet light emitted by the LED illuminator irradiates onto the fluorescent powder coating on the inner wall of the lamp tube, the fluorescent powder coating can be activated to continuously emit light. Mercury particles polluting environment are not used and the lamp tube is not vacuumized, thus the single-end LED straight tube fluorescent lamp has the advantages of energy saving, environment friendliness and long service life of an LED lamp and has the characteristics of large luminous flux and high unit power lumen of a fluorescent lamp, thereby saving energy and protecting environment.

Description

technical field [0001] The invention relates to a straight tube fluorescent lamp, in particular to an LED straight tube fluorescent lamp. Background technique [0002] With the continuous improvement of LED lighting technology and production technology, the use of LED has become wider and wider, and has extended from the original home decoration lighting to the field of reading lighting and ordinary daily lighting. Recognized advantages, it can replace traditional fluorescent lamps, metal halide lamps and conventional energy-saving lamps. Conventional straight tube fluorescent lamps are equipped with mains electrodes at both ends. The straight tube fluorescent lamps rely on electronic ballasts and starters to generate high-speed electron flow between the electrodes at both ends of the lamp tube and mercury particles, and rely on high-speed electron flow to activate the inner wall of the lamp tube. The fluorescent powder coating emits light. This kind of ordinary fluorescent...

Problems solved by technology

Conventional straight tube fluorescent lamps are equipped with mains electrodes at both ends. The straight tube fluorescent lamps rely on electronic ballasts and starters to generate high-speed electron flow between the electrodes at both ends of the lamp tube and mercury particles, and rely on high-speed electron flow to activate the inner wall of the lamp tube. The fluorescent powder coating emits light. This kind of ordinary fluorescent lamp has electrodes and filaments at both ends, the starting current is large, the voltage is high, the service life of the filament is short, the light decay of the phosphor coating is relatively fast, and the overall life of the fluorescent lamp is usually only 6 ~12 months, when the fluorescent lamp is scrapped, the mercury particles in it will pollute the environment
