Q: The LED fluorescent lamp tube breaks the LED light in the inside: If this is not bad, then look back, there should be a small power supply at the end of the aluminum plate, and the other end of the power supply is 220V. Another possibility is that lower-end LED products will be blocked (non-isolated). Is the aluminum substrate in addition to the SMT chip, also some electronics posted above, if the aluminum board intact, you also to the end, one 220 v mains interface on both ends

Q: How to replace old lamp tubes with LED tubes: To cut off the line from the ballast, 220V will be able to connect directly to the end of the LED tube.

Q: What are the types of leds?: The T5 is powered by a small lamp and no power supply. The component is the power supply of LED lamp tube, buy return is a light tube + a set of power supply, the installation time should use the old lamp tube support, also install the power supply

Q: Do the fluorescent tubes save electricity for 10 minutes, or do they save electricity in a split second?: If you turn on the lights for a second, it won't take more than 10 minutes. When any lamp is lit, there is a loss to the filament, so a temporary turn off the light is unnecessary.

Q: What is the distinction between led fluorescent tubes and ordinary daylight bulbs?: First of all, the biggest difference is that both luminescent principle. The LED fluorescent lamp is to rely on LED (LED, LED is a light-emitting diode, belong to the semiconductor light source. The common fluorescent lamp is by high-pressure gas breakdown stimulate phosphor luminescence.

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: The energy-saving device installed on an old-fashioned daylight lamp is similar to the lighting in the university library, where lights are illuminated and the lights go out: Heilongjiang wanfang electric equipment co., LTD. Is one of the places where you can check the Internet for sale

Q: How much energy does normal lamp tube compare with LED light tube?: When installed the LED fluorescent lamp is very simple, the original of the fluorescent lamp to remove the LED fluorescent lamp, ballast and electric fluorescent starter, let 220 v ac mains on both ends of the LED fluorescent lamp directly. LED fluorescent lights are up to 80 percent of the electricity, and more than 10 times that of a normal lamp.

Q: The circuit board in the LED fluorescent tube, what's the name of the component?: Have a what ah, whether to the power supply circuit, or light board, if do the power, you don't know now components, estimate for would you don't, schematic diagram, you seek me, send me zhang is out of date, don't mind, the new product is company secrets, if you want to power supply, it is good to look for me directly
