Q: LED lamp is not lit, how repair?: Looking for the warranty, you'd better buy a new one, if not this it hard to fix.

Q: The LED is low voltage and high pressure: Don't blindly pick, check whether it is capacitance step-down circuit. If it is not low pressure directly is burned out

Q: What kinds of leds are included?: You're right. GU10 is 220 v; And is MR16 GU5.3, MR16 is low voltage, common is 12 v, so when use usually need to match a small transformer.

Q: Drive power supply with a what kind of specification, can be in parallel two 3 wled shoot the light: Upstairs to answer the wiring method in theory can be bright, but if one of the lamp is broken, because it is a constant current driver, another lamp will inherit the double current, quickly burn out. So the correct connection is the use of double current unchanged, power driver, serial connection.

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: Smallpox lamp is max25w LED power rating, is 25 watts: Listen to sell the lamp. LED light is very save electricity. No electricity. Here I'll use leds. Only 10 w tube light.

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: 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: Excuse me how many W LED lamp appropriate gallery: Color rendering index suggested that more than 80 Ribbon star lighting technology

Q: What are the kinds of led lamp holder?: LED lamps and lanterns of species LED lights, LED street lamp (Light Emitting Diode, Light Emitting Diode) the semiconductor lighting. It is a kind of based on semiconductor PN junction formation with a weak electricity can glowing efficient solid-state light source, in certain positive bias voltage and the electrical flow injection, injection of holes and injection P N the electronic after spread to have source area by the radiative recombination and emit photons, convert electrical energy directly into light energy. It is a solid cold light source, green pollution-free, less power consumption, high photosynthetic efficiency, long service life, therefore, the LED street lamp will become the best choice of the road lighting energy saving reconstruction. LED project-light lamp, LED project-light lamp make specified by the intensity of illumination on the cliff above the lamps and lanterns of the surrounding environment. Say again the spotlight. Normally, it can aim at any direction, and has not affected by the climate conditions of structure. Mainly used for large-scale operations in mining, building outline, stadium, overpass, monuments, parks and flower beds, etc. Therefore, almost all the outdoor use of large area lighting lamps and lanterns can be seen as light. LED wash wall lamp, LED wash wall lamp, as the name implies, let the light like water washed metope, mainly is used for building decoration lighting, and used to draw the outline of the outline of a large building! Due to the LED energy saving, high photosynthetic efficiency, color is rich, long service life etc., so in 2013 other light source to wash the wall lamp is gradually replaced by LED wash wall light.
