Q:Which is good for LED patch and LED bulb?
Chip LEDLED patch lamp (SMD) is made of FPC circuit board, LED lamp and high quality silica gel sleeve. Waterproof performance, using low voltage DC power supply is safe and convenient, light colors, bright colors; outdoor use can be anti UV aging, yellowing, high temperature resistance and other advantages, the products are widely used in building lights, decorative lighting, advertising and entertainment quasi decorative lighting lighting field.LED bulbThe light emitting diode, is capable of converting electrical energy into visible solid semiconductor devices, which can be directly converted into electricity to light; LED Large Electronic = Display, LED = large electronic display; Lupus erythematosus disseminatus, systemic lupus erythematosus, a chronic idiopathic autoimmune disease; LED lead the past and past participle, meaning "leadership, led the Russian Pulkovo Airport IATA code.
Q:What is patch SMD-LED?
This really do not know how to answer you, like a sheet of the same type of solder paste used to operate, it can be said that the plug-in is not, it is patch it!
Q:LED patches have several ways of welding. Which ones can be reflow? What can be done by eutectic welding? Is the welding of viscose and lens material is required?
SMD patch products basically can be used in reflow soldering, especially a little note here that the eutectic welding is the connection between the chip and the substrate support or specifically, is the bottom of the chip after completion of production of coating material and a layer of Sikkim alloy, and then set up a heating zone in solid crystal machine package in time and a temperature of about 300 degrees, the realization process of the chip at the bottom of the Sikkim alloy melt and silver plated layer connection bracket, and a clear distinction between reflow.
Q:Patch LED beads can be bought in what place?
SMD LED lamp is now very popular, mainly because of long service life, but also rarely appear dead lights or dark, but there are many defects exist
Q:Is the forward voltage drop of the patch LED too large or too small?
If you have to be good or bad, then I can say "small" to you,Some clients have strict requirements for this
Q:What is the difference in performance between the LED plug-in and the LED patch?
The cooling of the plug-in is not good, because the plug-in's lamp foot, in order to save costs, generally use iron plus coating, heat conduction is not very good.The strength of aluminium alloy is not enough, it is easy to break, and copper is expensive.Relatively speaking, the patch is good, because the heat is welded on the PCB, copper or direct aluminum substrate cooling, patches near.Otherwise, why do high-power patch it?!SMT direct placement machine, a high degree of automation, low rate of bad.
Q:The ten patch LED lights are connected in parallel. The rated power is 5 watts. How much voltage do you need?
Shunt split current series split voltageIs your single lamp voltage rated voltageIn addition to the red and green LED lights, the voltage is between 2 and 2.4, and the other colors are 3 to 3.6V
Q:How to detect LED SMD beads
The output voltage of the digital clock diode file is not high, generally below 2.5V, so the measurement of LED lamp does not work, the best way is to external electrical measurement. If there are a lot of beads to measure it, can take a constant current power measurement.
Q:Patch LED market conditions
Chinese suppliers also offer mature, but less profitable two-color and trichromatic products, which are mostly used in backlighting, appliances, consumer products, consumer electronics and display. Despite low market demand, vendors continue to offer sideview SMD LED, including 335 (4008), 020 (3806) and 215 (2810)
Q:Why is the patch LED blue light dim?
If you choose the brightness of blue light in the light of the relatively high, so when debugging the white balance (by changing the resistance to change the current, and then change the RGB brightness LED lamp), it is difficult to transfer to the pure white. Therefore, when selecting the lamp, the blue light is generally not bright.
