Q: The difference between the LED downlight and LED lamp have?: Belong to the directional lighting lamps and lanterns, can only by the light of the opposite, its advantage lies in the more concentrated than general lighting lamps and lanterns of lamps and lanterns, usually used for general lighting or assist illume. With the continuous development of LED technology, the service life of the LED tube light now generally can reach more than 50000 small. LED lamp is embedded in the ceiling or wall, general lighting products is a kind of highly concentrated, usually it's light to the specified target position. Through light is used to emphasize important points. When working, due to the LED lamp produces high temperature, so the LED lamp when the choose and buy must choose the high quality product, otherwise it will produce safe hidden trouble. Now LED lamp is mainly used for all kinds of commercial space lighting and architectural decoration lighting, etc. At the same time to shoot the light is divided into low pressure and high pressure, proposal consumer had better choose low voltage lamp, due to low pressure lamp life relatively longer, the higher light efficiency. Shoot the light of the general lighting power factor to decide, good lamp power factor can reach 0.99, but the price is much expensive. On the second place in application to distinguish: LED tube lights are mostly installed in the ceiling, above ceiling to 150 mm is required to install. Of course, there are LED tube light is of the external type. General selection in the absence of the location of the dome light or droplight to install the LED tube light, the light is slightly softer than shoot the light. The LED lamp can be divided into several categories: type, hanging and embedded, etc. To shoot the light is divided into with transformer and without transformer. That belongs to the embedded in the ceiling.

Q: A transformer can shoot the light at the same time for several of the 12 v?: So see your transformer on load capacity and how much is the rated power 12 v lamp, also is the apparent power transformer (VA) is commonly used in, with the apparent power values divided by the lamp rated power (W) is commonly used in. If your transformer is 50 va, power rating of each lamp is 10 w, then can take a maximum of 5 lamps.

Q: One of the ten famous brands in LED lamp have? How to differentiate between light and guide lights: Become a must-have in the people living in the life of lamps and lanterns, in the quiet night nature is little not to lighting with lamps and lanterns.

Brand is osram China lighting co., LTD. Is the world's most innovative ability of lighting company, one of the world's two biggest source one of the manufacturers. 4. The flower lamp act the role ofing The flower on the product research and development to follow international cutting-edge design concepts, and through extensive market research, on the basis of the original style, combined with European and American classical features, or into the Chinese elements, or the use of modern fashion wind, through the combination of the material, style, color, product performance incisively and vividly. Above is about the content of the LED lamp ten big brands, hope there will be a help to everybody. Have a need to purchase a friend can collect, later also can draw lessons from the oh!

Q: How much time LED lamp life: A lot of manufacturer commitment is 3-50000 hours, because each manufacturer technical level, adopt a variety of reasons, such as the original life has long have short, long tens of thousands of hours, short a few months.

Q: How many W LED lamp can and ordinary 35 W lamp as light: Guess, and shoot the light, the LED light is a vain. The scene feeling LED high light point dazzling... Shoot the lamp to highlight the warm thick..

Q: The original old how long pole to shoot the light to LED lights: LED Chinese as the light diode semiconductor has positive and negative May be you take input power + - backwards and thermal conductive glue stick to a high power LED lamp bead need radiator panels mountain or you will burn out

Q: With current meter how to detect the led lamp lights, bad: Can find a lithium battery (or 3 section dry cell in series), series a hundreds of the resistance, to the led lamp bead, try on the reverse, if the light is good, light is not bad

Q: Led lamp can adjust luminosity: Is can make color of LED lamps and lanterns that move light, only the promise of dimming color LED drive power supply line,

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!

Q: The house that new clothes builds, pick up a LED lamp Specific parameter no receive wire didn't receive zero after electrify LED lights have a dim light An estimated 10% of the after less than fully open after disconnect all electrical appliances There are light which out of the question to solve the trouble is online, etc. ~: Each led lamp bead, voltage is only about 3 v, you put some static will dim, so is the problem of voltage
