Q: Buy what good LED lamp? How to judge the quality of lamps and lanterns is good or bad: Droop, good LED lamps and lanterns in 25000 hours before the light failure < 30%; Decided to light the main factor of failure is the stand or fall of light source, heat dissipation structure difference; Foreign original factory packaging of high power light source, such as CREE light source the light of the light source of failure is better than that of domestic packaging, as amateur can't see the light source, simple way of judging the main is the price that foreign light source of the original light source is domestic packaging price much higher; So if you want to buy good quality LED lamps and lanterns must provide light source manufacturer information.

Q: The difference between the LED downlight and LED lamp: Tube light is not good to adjust light downier light shoot the lamp to be hit out of the scope of the irradiation can see the light You can adjust the irradiation Angle

Q: Reinstall the 2 LED lamp are in parallel, one open and how a first shines a stare blankly only 1 SEC,: The power supply problem, this is normal Some different power frequency is the imagination, will not affect the lighting, are need LED lamps and lanterns is welcome to taobao And lighting professional high-power LED energy saving lighting products production and sales

Q: The LED lamp aging is what mean: So-called aging test, it is to evaluate the stability of the overall performance of lamps and lanterns, including electrical, optical, thermal test, general inspection need to define the time period, usually aged 8 hours, if it is a need to develop new products detection time, such as 300 hours. 500 hours. 1000 hours. 3000 hours. 6000 hours respectively according to different test, determine the stability of product performance according to the results of the test. In accordance with the relevant standards to determine whether the product design conforms to the standard.

Q: The led will shoot the lamp to warm the white heat?: Fever is for all the led lamp bead inevitable problems, lamps and lanterns is inevitable. So has the corresponding cooling measures or properly reduce the working current of the led to reduce fever, to extend and embody the characteristics of led high brightness, long life

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: What's the reason why LED lamp explosion?: The LED is a semiconductor products, semiconductor components how to fry, you first take a look at what is inside shoot the light structure, what of? LED lamp is the low voltage dc power supply, so there is a 220 v low voltage transformer, rectifier, regulator, etc, so easy to explosive components only capacitance. Light not bright, then is a problem with my line, not LED lights out of the question, you think about it, four straight LED lamp is not bright, it happens only line out of the question. 1. You check the dc voltage in a circuit is big (a big will burn out the LED voltage); Check if there is no failure to press 2 points; 2. Did you check the rectifier voltage regulator internal burned components (including capacitor); To eliminate the transformer in the 【 some lamps and lanterns, to step down with other components, if one element is broken (short circuit), it is possible to high-pressure came in." 3. You're not short circuit has been measured using a multimeter, you is which part of the test? You didn't speak clearly. Dc voltage test have no? How many volts? 4. There is another reason is that the power supply voltage stability where you live? Have 220 v voltage fluctuations, especially at night, usually higher voltage (more than 220 v), if the voltage rises to more than your pressure limit of lamps and lanterns, lamps and lanterns will burn out. 5. Etc.

Q: What is the main purpose of LED to shoot the light? What is the difference between it and the ball lights, mainly performance and USES.: Shoot the light is mainly to strengthen lighting In order to highlight, bright-coloured Shoot the light is small Angle The ball bubble lamp is mainly used for lighting, also can do canister light source

Q: The same power of cob and led lamp which is brighter: General use Taiwan chip COB light efficiency: 65 ~ 80 lm/W, the greater the power light efficiency is lower.

Q: LED two head lamp lines do not short circuit is not grounded on the total trip what reason?: Because this course has a problem! : insulation does not reach the designated position, there is leakage phenomenon.
