Q:Is there any flicker in the LED bulb?

Really, the voltage in our home is likely to lead to fluctuations in the LED bulb strobe in public, voltage instability will be more common, but most of the voltage is relatively stable, does not appear large fluctuations, so the strobe is not violent, but the fact is there. Questions raised by the questioner can show that you are observant.

Q:LED bulb with what type of LED beads?

Of course, the more high-end heat better use EMC3030 lamp, EMC2835 lamp and so on, please consult your supplier

Q:Want to buy a few LED bulb, do not know how to identify the quality of good or bad, ask for solution ~!

You are not the light source, in addition to a treasure bully ordinary consumers can't tell the difference between good and poor light source, all blow themselves jingyuan. I think you can see for yourself, not necessarily expensive or cheap but wafer, it certainly can not be said. Big power of a simple 1W bar, poor beads 1-3 cents, the wafer will be 1.3-2 dollars. There are several tiles, and how much does it cost?.

Q:Seeking the production process of LED bulb... Thanks

10 points, Baidu wants to be a LED engineer. LZ is a real budget man

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:I want to ask for high power LED bulb lamp wire inexplicably broke, and in large quantities. Is the quality of the lamp?

A sense of self is the following 1. package production process of wire bonding or partial welding weld. Whether the station is too large.2. through the current impact blanking line3. package factory using gold thread may be too fine

Q:Are there any differences between negative ion bulb and LED bulb?

LED bulbs are made by plug-in lights or SMD or high-power LED, and there is no built-in negative ion generator.

Q:Is it possible to manually weld LED bulb bulbs?

You can ignore the effect of heat conduction and thermal grease, solder is better, I was doing a lot of tests, the thermal conductivity of thermal grease is about 1.2 to 2, aluminum more than 300, thermal grease just to fill the bottom of the LED and the aluminum substrate contact surface gap, you don't fill gaps don't hinder it the normal contact with the aluminum substrate at the bottom of the LED, will be lost, and the use of thermal grease you for about a year will have to replace the thermal grease, only unscrupulous vendors will deceive others say I added thermal grease, heat conduction effect is not fully qualified, in fact, for a long time, the potential will LED light spot the chip inside the loose because of the long-term high temperature, causing the current growing, until completely off

Q:Led the bulb is flashing. What's wrong with it? How do you fix it?

There are several cases of flashing lights:There is one to three flashes when the switch is switched off. This is due to an incomplete discharge of the electrolyte in the power supply.The power supply is flashing fast. This is the quality of the power supply problems, there are many specific reasons.It is found that the design of the power supply is related to the structural design of the lamp due to the insufficient margin of the power supply and the increase of temperature!

Q:How to identify Ic constant current LED bulb?

Another is to destroy the bulb and see the power inside the bulb. Not a constant current power supply, only some capacitors, diodes, resistors, and the like. The constant current drive, in addition to the diode electrolytic capacitor, there is a 6 foot IC and a triode, there is a high frequency isolation transformer. To make it clear, you can take a look at it.
