Q:How to detect LED SMD beads
Resistance voltage ordinary pointer table 1.5V in general, and some only in the high resistance file (*10K file) with 9V or 15V battery, so the pointer table to measure LeD beads to hit the highest resistance profile measurement, otherwise useless, of course, at this time the brightness is very small, can not see, can only to judge the positive and negative resistance values see.
Q:Welding method and notice of SMT LED
The peak reflow temperature: 260 degrees or below this temperature. (surface temperature) 2 temperature over 210 DEG C required time: 30 seconds or less than this time. 3 reflow times: no more than two times. 4 after reflow, LED needs to be cooled to room temperature before contact with colloid.
Q:What is the principle used in SMD LED lamp, should pay attention to what the problem?
LED white is the light emitting diode, a PN junction to the most important use of SMD beads is the heat, according to the different manufacturer beads, glue package is not the same, should pay attention to pre baking time and temperature, the latter should pay attention to the patch temperature, the most important is the price, many manufacturers in order to cost savings, internal chip used is too small does not meet the standards, support steal frugal material, with iron, the failure cycle shortened, LED lamp can not reach the ideal effect. Again, the LED supply current must not exceed the rated value, which is an important factor in damage to lamps and lanterns
Q:The ten patch LED lights are connected in parallel. The rated power is 5 watts. How much voltage do you need?
The ten patch LED lamps are connected in parallel with rated power of 5 watts and voltage 3.3V.
Q:Which is good for LED patch and LED bulb?
LED (light emitting diode) patch (package)LED patch (SMD) made by FPC circuit board, LED, high quality silica gel. The 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 - Entertainment decorative lighting lighting field.LED bulbA solid state semiconductor device that converts electric energy into visible light by means of LED (light-emitting diode), which converts electricity directly into light; LED = Large, Electronic, Display,;
Q:Patch LED manual welding, how can welding not burn lights?
Recommend to communicate with older employees, they will have a lot of welding experience
Q:What is the difference in performance between the LED plug-in and the LED patch?
The same, stick pieces is an early product, stick pieces than patch mature, stick pieces of my lamp has almost can not see what changes for three years with only a patch of brightness, years have been feeling a lot of dark. I believe the quality will be good soon.
Q:How many volts is a single LED on the LED patch band?
3V or so, generally three, a group plus a resistor, power supply with 12V
Q:Is the forward voltage drop of the patch LED too large or too small?
Pressure drop does not mean good or bad, the greater the pressure drop, the better to choose the right for you
Q:LED light SMD LED package in what form, trouble you under the guidance of...
There are 3 types of LED packages: inline LED, piranha LED, and surface mount LED
