Q: Buy what good LED lamp? How to judge the quality of lamps and lanterns is good or bad: Drive power supply, and good driving power can guarantee the overall life of the lamps and lanterns, LED the theory of life and the life of the general drive power supply is 100000 hours less than 100000 hours. In order to guarantee the overall life of the lamps and lanterns, driving power supply is also a key link; On the other hand must be LED constant current drive, if using a low-cost constant voltage driver will shorten the service life of the LED. As an ordinary consumers how to identify the LED driver power supply of the good or bad? See a few parameters, droop, service life, light efficiency, and quality assurance period. To provide quality assurance for a long time factory production quality LED lamps and lanterns is good.

Q: What is the difference between LED lamp and LED lamp cup?: Simplified Chinese is not too different, a lot of people said to shoot the light is light cup, also a lot of people say the lamp cup is to shoot the light, had better have pictures confirm won't be sent to the manufacturer.

Q: Friends have told me that the Hong Kong star can lighting production of LED lamp, LED bulb light. LED daylight tube is very save electricity, I find for a long time to find, now share with you what? Who can tell me what is he power-saving principle?: Don't watch brand! What to see whether the use of chip, chip technology in abroad several factory hands, such as the United States kerui, Taiwan wafer and on electricity, Germany's lang. LED light source is a big trend, no stroboscopic high advantage is energy-saving life! Ordinary incandescent lamp with 80% energy into heat energy, LED light-emitting diode technology with 90% of the electric energy into light energy, energy saving, of course!

Q: What the reason, is led guide to shoot the light flashing?: And it is flashing all the time, regular flash,.Suggest to merchants repair or replacement.This is not necessarily

Q: The LED lamp and built-in ballast which good: I sleep standing still with a good outside. I was for my own use outside. I don't think inside is broken is not repaired? I now use is out of the blue card

Q: Led lamp light source plate can change yourself?: Change that can change, the overall is good, the inside of the bulb is not good to buy also is bad, because bad you sure is bad or the light bulb lamp body,

Q: Led bulb light beam width led ball steep light Angle is usually?: These lights in addition to the LED fluorescent lamp is 1 wled do, you will find your LED lamps and lanterns of parameter has its light Angle, generally is 160 degrees, one is 160 degrees, 10 or 160 degrees, what do you say? And the LED fluorescent lamp is made of 3528 LED, the light Angle is greater than 120 degrees

Q: Led courtyard lamp long good or single head: The upstairs to answer very professional. Lamp holder, the more the better, the single head can't be used if it is broken, the bulls' bad a lighting effect, and long heat dissipation is better than single head (this is important!) .

Q: How can you make the led lamp not dazzling: Into visible light solid state of semiconductor devices, it can be directly put DianZhuan into light. The heart of the LED is a semiconductor chip, chip attached on a bracket, at the end of the end is negative, the other end connected to the power of the anode, the whole chip is encapsulated by epoxy resin. Semiconductor chip consists of two parts, one part is a p-type semiconductor, dominated by holes in it, the other end is n-type semiconductor, here is mainly electronic. But this two kinds of semiconductor connected, forming a p-n junction between them. When a current flows through a wire to the chip, the electron will be pushed P area, electron and holes in the P zone compound, then will be issued in the form of photon energy, this is the principle of LED light. And the wavelength of light was the color of the light, is determined by the formation of p-n junction material.

Q: The sitting room condole top LED lamp wattage is commonly? How many watts of the LED lamp have?: LED is very good to recognize a beads is there are a few 1 w LED beads is a few watts of light. LED tube light, too, is the LED tube light to shoot the light are the same.
