Domestic waterproof LED lamp now mostly in54, when it comes to waterproof lights the main thing of its stability. However, do waterproof lamp has several aspects need attention:
One, be the first to bear the brunt of switching power supply. Standard practice is to use the PFC power supply, which is a very important reason waterproof lamp is often more than a dozen series together using. In this case the power interference will expand, may directly affect the signal lights, according to occasional chaos flash phenomenon. Of course, the software can use the look but can not completely eliminate. Specific to how to deal with and I can discuss. And with a PFC switching power supply efficiency ratio general without switching power supply high. So the price is more expensive, such as an 150W without PFC switching power supply with PFC200then go to 300. But some manufacturers in order to pursue the maximum profit of course does not take into account these.
In two, is the choice of lamp. Because the domestic LED price factors using the relatively few people. Generally only large companies use, but with the cost of production ( mainly led lamp price ) decreased with distance from the popularization is not far away. General domestic production lamp in my own understanding it seems the best quality because of the belongs to Xin Tian. ( and I don't know ), as Taiwan has Edison, American career ( stage with less ), OSRAM OSRAM and Korea semiconductor. This is a desk lamp main cost ( more than 50%) and lifetime of an emitting efficiency is the most important link. A good selection of lamp beads at least occupies the70% above. Found in many domestic customers bought lights just price other never. If you do not know your price pressure is lower actually lose more, because good beads and bead the difference that copycat version differs severalfold even ten times the price. Xin Tian beads than Addison luminous efficiency is low1/ 4 or so, Addison than Han half low 1/ 3( they get, have different or strange ). Many customers will ask me which is really good then I must say the price is better, actually otherwise mainly depends on your own to it, if you just played 15meters that I told you Xin Tian enough, if you hit 20meters. Enough, you hit 30meters with the Han half. No matter what beads selected according to their actual conditions and prices. You a table lamp again bright played or where, why are you more than I two lamps play range. You can't take the LED when the laser lights?
Three, process. Factories have their own patch machine beads with SMT reflow ah, why here does not say the small plant cannot, small factory equipment must generally do not have these ( but can be issued outside the processing). Many people do not outward processing after all price in there. They are in the LED following smear on the thermal silica, such short-term use is OK, but led calorific capacity is very big that you will give had dried silica gel,. Plus and aluminum substrate contact is not belong to the kind of metal welding direct thermal conductivity out but by the silicone heat the medium, since the heat conduction is slow so the manufacturers of LED with half the problem comes often die lamp, and a lamp brightness lower than an. Led lumen is direct and radiating relationship together ah, this must notice. Four, the selection of lens. Different manufacturers use LED lights on the lens, and the light emitting angle. No fine study. But manufacturers are recommended, but not necessarily the best recommendation, want to see you get yourself a illuminance meter slowly try ah. Mixed color what to try. Why do some manufacturers made out of LED hit very well, some manufacturers of a watch is outside the two loop, the intermediate here bright one point where dark point, this is they don't know is called" take doctrine", brought on by the. Some people say LED is simple. It than the luminance on the line of the well, you have to show your1A current half a year after you give me to buy one. Standard 700~ 750ma this big practice, small plant is to customers than the brightness of your800mA I give you to1A my light you buy me ok, heat dissipation and current are influenced by LED lamp life stuff, a lot of people bought that half a year or one or two months dark for many, mostly the two problem. In five, LED number selection. A lot of people ask me if you have done more than 108waterproof, I say no was very depressed because of the loss of an order. Of course I'm not saying108is no good. Why 54become mainstream because of waterproof lamp is a very important aspect of heat, because you make 108waterproof lamp that heat sink to do much ah, you installed several people carry the necessary? Now we are in with the first developed the factory method, a mold and then find a professional to do the radiator manufacturers buy radiator cutting with screw lock in the bottom of the lamp cap, radiating the three main elements of bar I do not say the junior middle school physics:1, contact surface temperature ( this is the outside temperature had no way, you fucking great words can be put in a refrigerator using), air flow speed ( some manufacturers use this, make a big bobbin containing a fan, and then do the heat dissipation problem boss, you do not recognize the point which is sealed you again how he still depends on the outside of the contact surface to heat. ). Three, that we used to increase the contact area for the professional manufacturers, fin heat sink, you will say why not make one of them ( the problem here aluminum die-casting process problem can't be pressed thin fins) can say you fin density higher thin so heat is better. Of course, in addition to other methods of active cooling fan, once saw a foreign vibration radiating, he then high-speed regular vibration heat sink is achieved and the effect is quite good, the hand is placed next to have blown out. But the price is also quite good. I hope China can use it, like the graphics card cooling tube is also a very good approach seems to have adopted. |
