Q:Patch LED light broken one, short circuit can use it?
Only when a constant current source is used, the LED in series can be shorted. For the shunt power supply shunt LED, the open circuit LED can be disabled without having to manage it. The short circuit must be removed
Q:What is patch SMD-LED?
SMD LED is the surface mount light emitting diode. It is a solid state semiconductor device that converts electricity directly into light. The heart of LED is a semiconductor wafer, one end of which is attached to a bracket, one end is negative, and the other is connected to the positive electrode of the power to encapsulate the entire wafer with epoxy resin.
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:How to install the patch LED lamp band?
More attention is paid to the lamp with waterproof and the installation of a solid in the outdoor installation, outdoor installation often adopts the mode of fixed card slot, need to cut and connected place, and indoor installation, just need another with waterproof glue, waterproof effect to consolidate the connection point.
Q:Patch LED beads can be bought in what place?
If you don't want to constantly change with it, suggest you go to OSRAM, Nichia, Corey, Taiwan Tongjia enterprise authorized agency purchase.
Q:Is the forward voltage drop of the patch LED too large or too small?
The pressure drop in the normal range is generally better. The smaller the pressure drop, the lower the power dissipation. The more you save the electricity bill.But not to say that the smaller the better, not in the normal range of low pressure drop products may be defective.In addition, the uniformity of the LED pressure drop is also important.
Q:What are the storage requirements of SMT patch LED (LED)?
Moisture-proof packing- anti SMD LED in the transport and storage of moisture absorption, SMD LED shall be placed in sealed moisture-proof bag, inside put damp proof agent for protection, and placed the humidity humidity SMD display card packaging bag.
Q:Patch LED manual welding, how can welding not burn lights?
When soldering, the temperature is best to be lower, and the average welding temperature is about 360. That's enough, because the melting temperature of the tin wire is about 220 degrees, so if it is allowed, the temperature can be reduced as low as possible.
Q:Why is the patch LED blue light dim?
The pressure drop of the blue light is greater than that of the red light and the green light. If the series connection is the same as that of the green light and red light, the current limiting resistor will tend to dim
Q:How does the LED patch lamp differentiate between positive and negative poles?
You can also use the ohmmeter's ohmmeter. To dial multimeter, to "ohm X1" file, the light emitting diode when the red pen is connected to the positive terminal of SMD LED, the black probe is connected to the negative terminal of SMD LED.
