Q: Buy what good LED lamp? How to judge the quality of lamps and lanterns is good or bad: Of high power LED light source or straw hat lamp or LED piranha type; LED lighting lamps and lanterns USES the high power LED as light source, the price is higher; Straw hat lamp or piranha LED price is very cheap, not suitable for the light source of lamps and lanterns lighting level.

Q: The LED lamp has been flashing, what is going wrong? Original drive 36 to 48 v, output voltage output in a new drive 40-80: Blinking is caused by the stroboscopic, caused by voltage fluctuation. For many reasons, zero line switch fire wrong, drive and inadequate capacitance can cause stroboscopic.

Q: Led12V3W's radio lamp is ac or dc: Friend, you ask, I don't anticipate someone can give you a accurate answer, because you said the illegibility of oh!!!!! There is a way is the LED many words, if you like AC DC if not dawn on directly, to see the light on! But note that this is risky, because there are may burn!!!!!

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: What about the size of the led light?: Size of the LED lamp Are generally as the lamp wattage increases with the increase. The general 3 w hole between 60 mm to 85 mm, according to the wattage increases with the increasing.

Q: How to detect the LED to shoot the light quality is good or bad: When many people in the use of LED to shoot the light, because buy the price so low in the ceiling to appear some problems, a lot of use chip production line lay out to make, do not match color temperature, brightness difference, short service life, the user need to pay attention to.

Q: 18 w changed other power drive not bright LED lamp, what reason be?: VF values of each lamp bead is about 3-3.4 V, so a series of at least 18 to 54 V, general situation, the output voltage won't do more than 50 V, because it is not safe (of course, the use of isolation was not drive), so will make it 2 and 9 series way for more than 27 V (voltage), but not see your driver clear this After a few short also cannot do 3 * 18 w, because your lights must be 1 w (300 ma), rather than a 3 w (600 ma), current headlight bead hold, within a few hours it broke

Q: What is the difference between LED track lamp and track light?: Difference is: 1, the shape design, track light is generally cylindrical and installation showing in the outside, ceiling are generally installed for embedded. 2, irradiation range is different. In general has slide rail track light, can move to a certain scope. Ceiling for embedded installation, flexibility is lower than the track light. 3, lamp holder of the rotating Angle is different. In general ceiling lamp can adjust Angle to a plane, generally between longitudinal are plus or minus 45 ° Angle range. Track lamp can adjust the Angle, and then two plane generally transverse 360 °, 180 ° vertically. Ceiling and track shoot the lamp to each have their own characteristics, the ceiling is suitable for the local lighting of fixed position, the light rail is suitable for mobile location of local lighting, so for the store to use track light because the shop need to constantly adjust the exhibits to cater to consumer demand, but also the flexibility of track light is greater than the ceiling. The right to have the correct use of lamps and lanterns, good decorate is a variety of lamps and lanterns collocation to adjust the light effect, not ordinary DIY take it for granted.

Q: How can you make the led lamp not dazzling: For general lighting, people need more white light sources. Hair white light LED successful development in 1998. This LED to GaN chip and yttrium aluminum garnet (YAG) packaging together. GaN hair blue chip (lambda p = 465 nm, Wd = 30 nm), high temperature sintering of YAG phosphors containing Ce3 + yellow light shot after the blue light excitation, peak 550 m nled lamp. Blue LED substrate is installed in the bowl reflection cavity, covered with thin layer of resin mixed with YAG, about 200-500 nm. LED substrate from the blue part is absorbed phosphor to another part of the mix blue with yellow light from fluorescent powder, we can get more white light. For InGaN/YAG white leds, by changing the chemical composition of YAG phosphors and adjust the thickness of phosphor layer, can obtain a variety of white light color temperature 3500-10000 k. This by the method of blue leds for white light, simple structure, low cost, high technical maturity, so use the most.

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.
