LED fluorescent lamp 　　 LED fluorescent lamp LED fluorescent lamp is made of super bright LED white light as the light source, and the outer casing is acrylic/aluminum alloy. The outer cover can be made of PC tube and has a high temperature resistance of 135 degrees. The LED fluorescent lamp is the same as the traditional fluorescent lamp in the outer diameter. The length is 60cm, 120cm and 150cm. The power is 10W, 16W and 20W, respectively. The 20W traditional fluorescent lamp (Inductive ballast) The actual power consumption is about 53W, and the actual power consumption of a 40W conventional fluorescent lamp (inductive ballast) is about 68W. The brightness of 10W LED fluorescent lamp is brighter than that of traditional 40W fluorescent lamp. The 16W LED fluorescent lamp is brighter than the traditional 64W fluorescent lamp. The brightness of LED fluorescent lamp is especially softer and makes it easier for people to receive. The service life is 50,000-80,000 hours. The power supply voltage is AC85V-260V (AC). It does not need a starter and ballast. It has fast start-up, low power, no stroboscopic, and it is not easy to see fatigue. It is not only super energy saving but also more environmentally friendly. It is one of the key products developed by the national green energy-saving lighting project and is the main product that replaces the traditional fluorescent lamp. LED fluorescent lamp installation is relatively simple, it is divided into two types of power supply built-in and external. When the built-in LED fluorescent lamp is installed, the original fluorescent lamp is removed and replaced with LED fluorescent lamp, and the ballast and the starter are removed, so that 220V AC The mains can be directly added to the ends of the LED fluorescent lamp. The external LED lamp of the power supply is usually equipped with a special lamp holder, and the original one can be used. Principle of illumination: The terminal voltage of the PN junction constitutes a certain barrier. When the forward bias voltage is applied, the barrier decreases, and the majority carriers in the P and N regions diffuse toward each other. Since the electron mobility is much larger than the hole mobility, a large amount of electrons diffuse into the P region, which constitutes injection of minority carriers in the P region. These electrons recombine with the holes on the valence band, and the energy obtained during recombination is released as light energy. This is the principle of PN junction illumination. Generally referred to as the external quantum efficiency of a component, it is the product of the internal quantum efficiency of the component and the extraction efficiency of the component. The internal quantum efficiency of a component is actually the electro-optic conversion efficiency of the component itself, which is mainly related to the characteristics of the component itself (such as the energy band, defects, and impurities of the component material), the composition and structure of the component. The extraction efficiency of the component refers to the number of photons that can be measured outside the component after the photons generated inside the component are absorbed, refracted, and reflected by the component itself. Therefore, the factors concerning the extraction efficiency include the absorption of the component material itself, the geometry of the component, the refractive index difference of the component and the packaging material, and the scattering characteristics of the component structure. The product of the internal quantum efficiency of the component and the extraction efficiency of the component is the luminous effect of the entire component, which is the external quantum efficiency of the component. The new energy battery materials developed and mass-produced by DADNCELL mainly include electrolytes for lithium batteries-high-purity crystalline lithium hexafluorophosphate, lithium tetrafluoroborate, lithium perchlorate, electrolyte additives and its anode materials, ultra-thin lithium ribbons; lithium carbon fluoride The core cathode material of the battery-functional carbon fluoride materials (customized micro-fluorinated, moderately fluorinated and other fluorinated carbon materials with different degrees of fluorination); the key material of thermal batteries-lithium boron alloy and lithium silicon alloy.

[1] Definition:
LED fluorescent lamps can save more than 80% of electricity, and the lifespan is more than 10 times that of ordinary lamps. It is almost maintenance-free. There is no problem of replacing lamps, ballasts and starters frequently. The cost saved in about half a year can be saved. Exchange back the cost. Green and environmentally friendly semiconductor electric light source, soft light, pure spectrum, is conducive to workers' vision protection and health. The 6000K cold light source gives people a visually cool feeling, which helps to concentrate and improve efficiency.
