Main Technology Index:

Q: The difference between LED and fluorescent lamps: Fluorescent tube filled with low-pressure argon or argon neon mixed gas and mercury vapor, and the inside surface of the fluorescent tube in the glass is coated with phosphor fluorescent paint, has made of tungsten filament in the ends of the tube coil. When power on, first of all, current through the filament heating and release the electronic, electronic tube gas into plasma, and make the tube current increase, when the voltage between the two groups of filament lamp began to produce discharge after more than a certain value, the mercury vapor from 253.7 nm and 185 nm wavelength ultraviolet, fluorescence phosphatic fluorescent paint on the surface of the pipe inside can absorb ultraviolet light, and release the lower wavelength of visible light. The color of the light is controlled by the proportion of phosphor, while the glass tube avoids harmful ultraviolet rays and other harmful substances

Q: What is the most suitable power efficiency for leds?: It's about 0.97, it's still pretty high, I bought the lamp tube of zhaochang, very bright, used for two years, still like new

Q: What's the difference between an LED fluorescent lamp and a regular fluorescent lamp?: With 15wled, you can replace 40w plain fluorescent lamps, which is more efficient, but more expensive

Q: How do I get the four joints of the LED fluorescent tube, and I'm going to do any two of them that can search through the AC220V to light up, and not make the wire and the zero line together? thank you: I can't put a picture on it, you can try it yourself, add a rectification bridge at each end of the tube, and then you put the positive plus positive on both sides, negative plus negative, onto the next bridge

Q: Help me see the yellow on the left side of the LED fluorescent lamp: It should be a stabilizer module; The other, the left, 1, 3 is the inductor. 4, 5, 9 is the filter capacitor; 6 is also a capacitor; 7 is a triode; 8 is the transformer.

Q: The same thing is 5w, is this LED tube power or is this a fluorescent lamp?: Yes, the power is the same, the power consumption is the same. But leds are brighter than daylight.

Q: Use LED fluorescent lamp tube to replace, the line of original daylight-tube seat should be refitted: So old ballast, the ballast uninstalled, directly to the card on the two old fluorescent lamp wire short respectively, and then to the outside power, install the LED fluorescent lamp with respect to OK

Q: How does the LED fluorescent lamp tube be fixed with the aluminum plate in the tube?: The person thinks still silicon fat + screw, but the screw is not easy to install, do not know the big man has the gao zhao4?

Q: What is the category of LED bulbs, T6, T8 or whatever?: Each "T" is 1/8 of an inch. An inch is 25.4mm T12 is 38.1 mm in diameter T10 diameter 31.8 mm T8 diameter 25.4 mm T5 diameter 16 mm T4 diameter 12.7 mm T3.5 diameter 11.1 mm T2 diameter 6.4 mm The number behind T is the perimeter of the lamp. For example, T4 is 4 centimeters, and T5 is 5 centimeters. search That is, the number in the back of T is one eighth of the 25.4 millimeters (1 inch), which is the diameter. Originally, only the electric inductance ballast, "halogen powder" the fluorescent lamp.

Q: What lamps and lanterns does the supermarket illuminate to use what lamps and lanterns province electric LED fluorescent lamp tube: The most radar microwave-sensing LED fluorescent lamp is better, and it is always bright when someone is on the radar
