Q: The difference between LED and fluorescent lamps: Leds are composed mainly of PN junction chips, electrodes and optical systems. Its luminosity - the chip's area of 12 * 23mil (1mil = 0.0254mm), currently has a large chip LED in the world, with a total area of 40 * 40mil. The process of luminescence consists of three parts: fluid injection, composite radiation and light transmission of positive bias. Tiny semiconductor chip is encapsulated in the pure epoxy resin content, while the electrons through the crystal, negatively charged electrons move to the positively charged hole area and complex, with disappearance of electrons and holes at the same time produce photons. The larger the energy between the electron and the hole, the higher the energy of the photon. Photon energy, in turn, and the color of the light, the spectrum of visible light range, blue light, purple light carrying the most energy, orange colored light, red light with the least amount of energy. Because different materials have different bands, they can emit different colors of light

Q: I hope my answer will help you: First push the lamp tube at either end. So the lamp is coming down.

Q: The difference between an LED tube and a daylight lamp: As far as I know, fish like blue and green light. So when you choose LED lamp tube, if feel blue light and green light LED lamp tube is too frivolous, choose color temperature is taller

Q: The child lamp chooses led good or the lamp tube is good: Light color chooses yellow light, because yellow light is the most natural incandescent lamp, rely on the filament to shine, current through the filament that the electric resistance is great the filament will be hot and glow. Such light is continuous no flash. And white light is the light that fluorescent lamp is called energy-saving lamp fluorescent lamp. Energy-saving lamps and fluorescent light stimulate phosphor luminescence principle is to use some kind of radiation, like light is discontinuous, which is a seaside sparkle, but quickly, eyes have a vision for the role of, feel the light in a flash. It's bad for your eyes to be in such a light for a long time.

Q: What is the minimum starting voltage for the fluorescent tube?: The fluorescent lamp is under the influence of the ballast, the voltage is 810 volts. 810 volts is transient and can only be observed with a digital oscilloscope. I measured the data in three different meters, and the data doesn't really have the same data.

Q: The same thing is 5w, is this LED tube power or is this a fluorescent lamp?: In addition, under the condition of equal brightness LED lamp power is only 1/3 of the ordinary energy-saving lamps, so the same space, if use 20 w fluorescent energy-saving lamp tube, then switch to 8 wled lamp is bright enough. From this point of view, the electricity is greatly saved.

Q: Use LED fluorescent lamp tube to replace, the line of original daylight-tube seat should be refitted: Hello friend, I know you said of that kind of old-fashioned fluorescent lamp, there are two base, base on the inside are two elastic brass plates, you may be putting cover the outside of the plastic part of the brass screw is broken? It doesn't matter, just use your lamp plug contact on the brass base and bare department if you fear of insecurity is with insulation tape package no problem!

Q: Is a three-male LED fluorescent lamp? How the quality?: All the leds in sanxiong are made of the chip of the corry, which is very expensive, which is about a dozen times better than the normal LED product, but the quality, the light color aspect is not to be said, very good. See the product that you want to use good or general, want to use good can choose, if required, recommended the other manufacturers, including, Anatole, group of states, Carl is fine.

Q: Currently, the 48-inch led fluorescent lamp tube 18w is used for how much dc voltage: The voltage in each company is different, and you have to ask the manufacturer.It's usually made of 2835 chips, about 60mA, or about 3.3 volts.

Q: What lamps and lanterns does the supermarket illuminate to use what lamps and lanterns province electric LED fluorescent lamp tube: The supermarket illuminates LED fluorescent lamp tube, LED grid lamp, LED bulb lamp/LED bulb bubble lamp is the most province electricity.
