Q: 1. I bought the LED tube light, there is some light is driven with constant current, while the input voltage is 220 v, but tend to be low voltage dc output voltage, there are some inserts the 220 v can directly, didn't see any of the constant current drive, so is built into the still say there are two kinds of LED tube light, is a kind of the working voltage of the dc low voltage, a kind of ac 220 v. 2. About the LED tube light, dimmer, I already according to one of the LED constant current drive found the corresponding LED light, that if I was the LED directly to the adjustable light can directly replace the LED constant current drive.: LED lamp bead are dc low voltage, single grain lamp bead generally around 3.3 v voltage can light up, general household LED light has many grain of lamp bead, most of them are in series, no matter which kind of LED lighting needs to be in the form of a voltage conversion device, the voltage conversion device also has a built-in external, have stable manifold has regulated form, useful integrated circuit do useful discrete component, with complex circuit has simple circuit, there are lights and conversion circuit package together also have lights and conversion circuit of separate, anyway is multifarious, various countries now also does not have a specification, each manufacturer yourself, just do what want to make it, so they bring inconvenience to the user, so the home LED light damage, it is difficult to buy the same, every time in the lamp will also ask professional to listen to, you say the problem is not surprising, is likely to be a built-in driver, another oneself need plus drive without a driver.

Q: How to choose to shoot the light: LED lamp USES chips: there are domestic and Taiwan chip, chip imports. The chip is different, the price difference is very big. Imported chip prices more expensive, very few people use in the domestic market, the mainly for high-end customers. In the end the customer general selection is now Taiwan chip, is one of the best cost performance

Q: Led lamp can use ordinary incandescent dimmers adjust brightness.: So, be cautious if it don't go with LED lamp dimming, unless you use the LED light source manufacturer specifically recommended combination of transformer and dimmer, otherwise, can need not to test. Lights are old expensive, spend money not worth it. In not, want to use cheap ordinary dimmer, then you might also use halogen lamp cup shoots the light, technology is mature, the dimming effect is better, while demanding more electricity, but light also cheap ah, only 3 to 4 yuan a, it is important to the dimming effect is good, stable, color is also the highest, much better than common LED to shoot the light.

Q: With more coarse thread is better, interface to reserve in advance before woodworking? Also need to be buried in condole top, wire inside the wall?: Had better use soft wire, good construction. Main line with 2, 5, a lamp need not so thick.hope it works for you

Q: LED to shoot the light is not very bright, or where the flash is broken?: I will do it for you, I myself solved the same problem with you, first determine in power, is the drive you say is useless, it sure is a problem of lamp bead, the lamp will be unwrapped LED lens until you show bead, flat on the table, the lamp lights up, access to electricity, you get a wire, wire stripping out at both ends of a nod to ready you can use this wire to short circuit test lamp bead, is to use this wire ends to point in a lamp bead on two feet, a light bead lamp beads point, until the point in a grain of lamp bead suddenly the lamp height is normal, so congratulations you, you find the bad, take it with a thin copper wire electricity ferrochrome in bad light bead welding of two feet on the KO, then there may be some friend to ask, if broken two or three grain of lamp bead to do? , it doesn't matter, you when I come back again hair a question answer just forget to summarize, why w leds will appear such circumstance, because this dozen grains is in series with the lamp bead, so a single bad overall don't bright

Q: How do I get the light: Incandescent light bulb or lamp, energy-saving lamps lamp mouth two wires, one switch output terminal, a line connecting the zero. If they are LED to shoot the light, rated voltage 220 v connection method with the same; The needs of the 12 v and matching drive connections, two lights at the mouth of the wire connecting the output end of the drive. Drives the input, a connection switch output, a line connecting the zero. Incandescent lamp power consumption; Energy-saving lamps take second place; The LED light source is the most energy saving, long service life.

Q: LED to shoot the light flashing or not on how to deal with?: You use multimeter to play your first whether the voltage stability?

Q: How to adjust the light in the home: See shoot the chip quality LED the quality of the core difference between the chip and the market of conventional can buy high-end LED lamp chip is generally the pury, some use Taiwan wafer, Taiwan macro light, the lowest will choose domestic chip. Chip quality decision brightness, life, light failure, etc.

Q: LED two head lamp lines do not short circuit is not grounded on the total trip what reason?: Should be a short circuit, first down to shoot the light, open switch, if can open, is lamp short circuit, if not is the line short circuit!

Q: How bright LED globe bulb 5 w? The light is to shoot the light, or like a glow around?: LED bulbs light Angle is at 180 degrees, glow, around 20 square meters room, five are very bright, of course, if one, may be not enough light
