- Q: The lighting is replaced by LED lights and circuit problems
- No, you're going into a ballast, one is out. The picture you gave is only part of it. When you disconnect the ballast, connect the same color. The red one is the wire, the current of the ballast. After disconnecting, it should be a connection between the red wire and two broken wires. You should shoot the right wire again. The situation in my home was to tear down the ballast and the two red lines were connected to the red line. The green earth line connects to the blue line. You have to capture the essence of the problem, and you have to see the current flowing. The current must be in and out of the ballast. When you disconnect the ballast, you should connect the broken one to the other. This will make the current pass.
- Q: Can leds be used for a regular fluorescent lamp?
- LED lights do not use ballast! They work in a completely different way.
- Q: The same thing is 5w, is this LED tube power or is this a fluorescent lamp?
- Power consumption is the same, but brightness is different.The fluorescent lamp is good for people's eyes, LED saves electricity, oneself choose.
- Q: A 36w daylight light with a watt LED lamp?
- Again, the traditional fluorescent lamp is an all-round (360 °), a most of the waste in the back, actually the total quantity of light for lighting only 60% ~ 65%; General LED fluorescent light emitting Angle 120 ° ~ 180 °, is essentially effective light. Calculate this method.
- Q: Why does the led fluorescent tube have water vapour in it? What causes it?
- LED fluorescent tubes have two functions: mixing light and protecting leds. Therefore, the air tightness of the shell is not too high. When the fluorescent lamp, LED heat pipe air heating expansion and discharge pipe, the fluorescent lamp is turned off, the tube air temperature is reduced, the air outside the tube back to the tube. This process is called "respiration." In the breath, the water vapor in the air is brought into the tube.
- Q: Led lamp tube t8 good or t5 good
- The specification of fluorescent lamp is the diameter of tube, length. Look at your lighting requirements, T8 pipe size, of course, the light effect will be better, the same length of lamp tube T8 will be more than twice as bright as T5, and the brightness is much better. The quality of the lamp is not so good at present. The main view is lamp tube with light, electric power and heat dissipation processing.
- Q: Buy LED fluorescent tubes to see which parameters
- Input voltage You can see some wide input voltage is the voltage of the tubes, is commonly - 265 v / 85 v AC, when the power supply voltage fluctuation in large will play his role, will not affect the brightness as the voltage fluctuation Isolated source and non-isolated source The safety of the isolated source is high and the price is relatively high. Though not isolated power supply security than isolated power supply, completes the safety measures, price is very high, especially in terms of efficiency and power factor, advantages are more obvious. Resistance capacitors and high voltage IC power sources are cheap, but they produce stroboscopic and low security.
- Q: What is the price of an ordinary daylight lamp outside? That's the kind of...
- This kind of fluorescent lamp saves electricity, do not have the sound, environmental protection, safety, is now a lot of family is used, ordinary fluorescent lamp is beginning to go down now
- Q: ?The title What is the color temperature of the leds?
- So the light that you're talking about is a little less red than warm, so it's a little less than 3000K, right?
- Q: It is the telephone of some enterprise management that asks me to take good use of, ask me how to use, how to contact them, what should I say when contacted I am a salesman
- If it's a business that already has business! Then you must cherish and keep in touch! If you want to keep up with the list, let's make sure that you are learning to do business. It may not work very well, it will take time!
