Q: LED how does the bulb return electricity?: What is reflow? Never heard of it. I am a lighting technician

Q: What's the cause of the noise during the aging of LED bulb bulbs?: This should be the power problem. It's easy to make a noise because there are so many parts of the power supply.

Q: How does the LED bulb go with the power?: Generally we use the LED lights, 1W, 2W, 3W, 12W, and so on, the factory has been set in advance, directly connected to the 220 volt power supply can be, and do not need to be so complicated.

Q: Led the bulb is flashing. What's wrong with it? How do you fix it?: There is a drive power failure, and if you do not electronic repair ah, it is recommended to return directly to another driver, generally have 1 years warranty period

Q: What are the requirements of the LED series inspection specification for bulb bulbs?: Insulation resistance: the lamp should not be placed for 48 hours in the damp box with relative humidity of hours. The air temperature in the box shall be controlled at any value between 20~30 degrees centigrade, and the temperature difference is within 1 degrees. The insulation resistance shall be measured in the wet box. Now the DC voltage on the lamp is about 500V. After 1min, the insulation resistance test will begin. The insulation resistance between the lamp holder, the current carrying metal parts and the accessible lamp parts shall be no less than 4M ohms.

Q: What is the AC voltage of the LED bulb?: The LED lamp is either a constant voltage drive or a constant current drive without AC voltage. Generally through the drive circuit filter rectifier, LED bulb bulb voltage is about 10V. Add: different drive circuits, different amounts of LED chips, the final voltage is different.

Q: What does the LED bulb patch mean?: The patch is referring to the lamp is put up, refers to the non patch lamp is plugged in, the distinction is probably a stick is inserted.

Q: What advantages does LED bulb replace energy saving lamp?: The response time is fast, the energy saving lamp is millisecond, and the LED light is nanosecond

Q: Led what's the flash of the bulb?: So, this is the power overheating protection at work. It will not be the case if the outer shell is enlarged or the room is ventilated and the heat should be cooled.

Q: Why can't the voice switch control the time of the LED bulb?: Current problem. The current is too weak. You don't have to use an electric meter to see if you can work properly without a light bulb. Change the timer switch.
