Q:What material is LED fluorescent lamp fittings, such as shell, block?

The bottom case is pure aluminum, solving the problem of divergence; The mask is a PC milky white or transparent to solve photoelectric transmission and visual effects. The plug is made of plastic, not easily broken and safe.

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power, you don't know now components, estimate for would you don't, schematic diagram, you seek me, send me zhang is out of date, don't mind, the new product is company secrets, if you want to power supply, it is good to look for me directly

Q:A 30-watt light bulb can be used for a change of LED lamp

Replace the led tube with rewiring; The original fluorescent lamp ballast is usually removed, and the led tube is a single terminal connection or a double end connection. If you look at the packaging or instruction of the led tube, there is a connection method.

Q:Why is it that when my electric car is charged, the light bulb is burning in the house, and the incandescent lamp is fine, and the other appliances are normal

It is possible that the high frequency pulse of the charger inside the charger is flowing into the power grid, causing the fluorescent lamp ballast to work and burn down. Electric car charger belongs to the circuit structure of the switching power supply, and the internal vibration circuit is used to produce high frequency signal to drive the transformer. Please use the TV interference method to test electrical good or bad. Put the charger in the TV next to blunt electricity. Television will have interference image will solve the problem that there is something wrong with the charger repair and replacement..

Q:A 36w daylight light with a watt LED lamp?

The luminescence of a 40 watt (plus 8W ballast) lamp is: 53 lumens * 40 watts * 65% (effective luminescence) = 1378 lumens; An 18-watt LED lamp has a luminous amount of 80 lumens * 19 watts (real consumption) * 100% (effective luminescence) = 1520 lumens. Above all, the light effect of the 18LED fluorescent tube is more than 40W traditional lamp tube (real consumption 48W). The other performance advantages and features of LED fluorescent lights can be found in baidu for "green fluorescent power" to visit our website.

Q:Excuse me, the lamp in the sitting room lamp is carried good or the lamp tube is good

The experience that USES me to do a dozen years to do lamps and lanterns, the best is to adopt T5 lamp tube, its advantage is: the life is long, and bright. The small beads in the lamp band are easily broken, although the price is cheaper, but it is more difficult to change frequently. In the end, a lot of guests will change it.

Q:If the led lamp is replaced, the lamp power should be small

Yes, there is a difference in color temperature between 14 and 18W.Yeah, how else to say energy efficiency

Q:How do you know whether a fluorescent tube is good or bad

In the case of leds, there is no direct way to judge the use of a multimeter. That will be in the absence of special apparatus, find a good matching of drive, according to the manual connection method directly connected, electricity testing. It's good to lighten up. Conversely, still.

Q:What is the conversion between the number of leds and the number of tiles?

In this case, we'll talk about energy efficiency.I hope my answer is useful to you.

Q:Led lamp tube t8 good or t5 good

This depends on where it is used, and the average household or supermarket store is using a t8led lamp. The t5 lamp is used in special places
