Q:Why don't leds need a rectifier

Because LED is a direct current is needed to light, and the output voltage of rectifier is an alternating current, so can't use rectifier, now LED lamp is built-in power inside, and use it every time you'd better put fluorescent original rectifier and demolition of the starter, but given the easy to use, now LED lamp can be directly on the original fluorescent lamp holder, do not need to disconnect the rectifier, only need to send a link of the starter circuit cut. Because the regenerator will provide an instantaneous high voltage, it will damage the LED

Q:Put on the new light bulb, why the lamp still not bright

For the electronic ballast, if no response after the power supply the tubes, should first check whether the fuse of the ballast burned, if it is a filament is red, estimation is ballast resonant capacitance breakdown.

Q:Which is better? In terms of power and price

Light source (3528, 3014, 2835 light bead), baseboard (aluminum plate, glass fiber board), aluminum profile, PC cover, power supply (isolation/uninsulated constant current power), block head. The light effect is connected with the power and flux of the light bulb, and I wonder what you mean by this LED lamp structure.

Q:Can the LED tube be installed as a general lamp holder? It won't burn easily

Cannot be installed directly, need to change internal wiring. Leds are not the same as the traditional lamp tubes, which have the power supply inside the LED tube, and the input voltage at both ends of the tube is 220V. The traditional lamp power source is placed outside, and the voltage at both ends of the lamp is as high as a few hundred volts. If the LED tube is directly installed, it will burn down the power in the LED lamp tube because of the hundreds of volts of voltage that the original fluorescent lamp's ballast outputs. 3, therefore, the LED light tube cannot be installed directly in the traditional fluorescent tubes, the need to remove the internal ballast, then change the input at the ends of the line. LED bulbs are usually two incoming lines, one firewire and one zero line.

Q:Can a fluorescent tube be used in series?

How much voltage do you need to get through the two 20-watts series, and can a 40-watt ballast provide that high voltage? I don't think so.

Q:Is there any LED fluorescent lamp that can be used for more than five years?

LED lights are used for start-up time, and if it is open tomorrow for four to five hours it should take five years, but there will be light decay.

Q:What is the idea of an LED daylight lamp called T5 or T8?

The so-called integration of T5 and T8 tubes, we can understand from the literal Angle, explained the T5 / T8 I won't do, you should know. Let's look at the integration The so-called integration is lamp and stents are conjoined. From what we often see T5 and T8 are generally and stent can separate the tubes, can say down from the scaffold tubes, and the integration of can't get down. I want to say so, you should be clear!

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:Are led fluorescent tubes not available for lighting?

If home have a stent is built-in LED lights to be the most is to take the rectifier, and the external power supply is to use the power of the manufacturer to provide, so to be more back to safe some more energy efficient, at the same time LED the longer service life

Q:Fluorescent lamp fire line zero connection

My own LED lights are connected by the zero and the wire, and then the lights will have a very faint afterglow, which will be visible at night. I don't understand. I don't know if I have to reconnect the line.
