Q:Help me see the yellow on the left side of the LED fluorescent lamp
The black patch in the rear of the capacitor is the MOS tube, the electric inductance behind the MOS tube, the optical coupling behind the inductance, and the electrolytic capacitance behind the optical coupling.
Q:I hope my answer will help you
Rotate it, or you can move the tube to the right and try it.I hope my answer will help you.
Q:What is the difference between the daylight lamp tube used in fishing steel and the normal lighting tube
Second, LED lighting is high in light and high in brightness. Now the good LED fluorescent lamp can achieve more than 130, which is about twice the photoeffect of fluorescent lamp. In other words, the 18W LED fluorescent lamp can be a 36W fluorescent lamp. And from the actual lighting effect, the 18W LED light of 130lm/W can be used as a fluorescent lamp of 48W.
Q:Can compatible inductance ballast, electronic ballast led fluorescent lamp tube which have to sell?
Technical implementation is a little difficult. And instant implementation, price estimates are not low.
Q:Electronic ballast tube lamp change led lamp tube how to change circuit how to do
This is going to look at the LED lights that you're changing.I hope my answer will help you.
Q:How much is the ballast of the fluorescent tube coming out
The fluorescent lamp ballast is not to be understood by the idea of the current when it is activated in the lamp tube. The lamp tube of different wattage matches the current of the ballast of different current and the current is too bright or hard to start. Inductance ballasts, for example from 8 w15w20w30w40w when it in tubes without ballast between the output voltage and the zero line is power electricity after being connected in good tubes start according to the voltage at the ends of the lamp power different lamp in 80-110 - v, about 40 w at the ends of the tube voltage 110 v. Electronic ballast is the principle of the second inversion of high frequency oscillation. The output power is achieved by the size of the current supplied by the booster coil. The single-strand wire of the 13W booster coil is made, 25W with a two-ply line of 36W with 3 strands of 55W with 7 strands of gauze, the more power the larger the need of the current. Because of using ordinary multimeter is not suitable for testing the high frequency alternating current (ac) in maintenance electronic ballast can be ignored when the output voltage and to detect components mainly including tubes.
Q:How does the traditional daylight lamp tube replace the LED light tube?
Please follow the instructions from the LED light tube manufacturer. Different manufacturers will be slightly different. You can only short-circuit the reactor that was built into the lampstand
Q:Why do LED bulbs have stroboscopic frequency? The camera
It's a huge secret to be able to look at led lights and take a camera, and god lets you discover a huge secret, hehe. Secretly tell you You use your camera to photograph corrugated and stroboscopic, indicating that your led tube is a product that is resistant to pressure and pressure, not a product that is heng-current. Stroboscopic because domestic voltage changes back and forth between 180-260 - v, voltage changes in current led products to you after the impact, and your drive is not out of constant pressure, will only make the led lamp bead to under the impact. Simply put, your led tube is not very good, and it will soon be weak and not very long. Ask you to buy the time to ask clear, the lightning led lamp tube and the bracket on Tmall is the cross current constant pressure, can go to see. I hope I can help you
Q:How to connect the power supply when the LED lamp is energized?
Of course, the difference between the positive and the negative is positive, and remember that the leds are dc, and the dc is positive and negative. LED tube long legs are positive, broken leg is negative
Q:How many leds will be able to reach the 30W T8 lamp?
18 w leds can be Reach the brightness of 30W T8 bulb.It is a white LED diode used for a regular charging flashlight.
