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: LEDPAR lamp, LED lamp, LED downlight, users don't, the usefulness of various lamps and lanterns?: LED is not hot Ordinary fever Led energy saving transformer occupy a space more concentrated light In a certain range is not very bright

Q: What is the difference between LED GU10 and ordinary lamp: The difference between lamp and tube light Canister light and shoot a lot of people are confused, I don't know what is the difference between the two types of lamps and lanterns, what position to apply to the household, and the effect of the application. Canister light, simple says, is a kind of relative to the general with the lamps and lanterns is more concentrated sex of lamps and lanterns, is generally used for general lighting or assist illume; The lamps and lanterns of shoot the light is a highly concentrated, its light is a specific goal. Mainly used for special lighting, for example to emphasize a very tasty or is a very interesting place.

Q: The original old how long pole to shoot the light to LED lights: Transform the power The lamp is with electronic transformer is 220 V / 50 hz ac DianZhuan into 12 V high frequency alternating current (ac) for the use of shoot the light, for the LED power supply. Now should be high frequency ac DianZhuan into 12 V dc 12 V, so that power can be multiple groups of three series of LED lights (in terms of each only 3.5 V), each lamp visible need more groups in parallel, in order to reach a certain brightness. To add a high-frequency electronic transformer rectifier filter circuit, it can be high frequency ac DianZhuan into 12 v dc 12 v. Rectifier with high-frequency rectifier tube, HFC L can use energy-saving lamps of the circular on the glass with plastic envelope around 10 turns the substitution. Cut a small piece of PCB on the above components on the electronic transformer, after connected with insulated wires - and into electronic transformer molded case, output leads to +, - two power supply line.

Q: LED to shoot the light on when why?: LED lamp bead quality is bad, the power supply is not stable. Try suggested a change of power supply.

Q: What is the difference between LED ceiling lamp and LED downlight: Tube light is owed to the dark mounted, diffuse light, mainly to adjust indoor light color effect,, shoot the light is mounted, direct light, is mainly used to highlight the background picture or object, two kinds of lamp is installed at the top. LED tube light is a kind of relative to the ordinary lamps and lanterns has concentrated sex of lamps and lanterns, is generally used for general lighting or assist illume. The lamps and lanterns of LED lamp is a highly concentrated, its light is a specific goal. Mainly used for special lighting, for example to emphasize a very tasty or is a very interesting place.

Q: The led will shoot the lamp to warm the white heat?: All the leds will be fever, warm white and white or cold white calorific value is the same, different is only a person the sense of light, is not the same light warm white hot than cold white.

Q: The led lamp is suitable for reading?: Oh oh, that you can have a try, see feel dazzling, if not still don't used to read a book!

Q: How to distinguish the LED lamp wattage?: Look at the size of shoot the light, usually different wattage of the radiator is not the same.

Q: Led to shoot the light is broken how to change: Now turn off the lights switch (for safety) had better be to turn off the total power supply, and then into the drive power line (also can be directly cut short), then remove the bad driver And then put the new drive power input skin, two light thread dial the skin. Let one of the root drive power cord wrapped around the lamp power cord (chaozhou both positive and negative), on the one of tie up good, good electrical tape, another root connection same good tangle on electrical tape.
