Q: What determines the brightness of the patch LED?: Lamp brightness level itself, is also in the rated current situation, its brightness

Q: Production of a number of substrates, the use of SMD LED lights, red lights and green lights are not bad, blue lights appear mass dark, do not know why? Is the LED blue light material easy to use dark?: 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 placement lamp distinguish the positive and negative poles? There is no sign on the light. Thank you: 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.

Q: Patch LED light does not flash, why?: There are three main reasons:1, the temperature is too high, resulting in LED lights, dead lights.2, do not do anti-static measures, electrostatic breakdown chip, resulting in damage to the LED light.3, the use of LED lamp quality is too bad, the purchase price reasonable LED lights

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: Which is good for LED patch and LED bulb?: The LED patch is the same as the LED bulbLED (light emitting diode) patch (package)The LED patch (SMD) is made of FPC circuit board, LED 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 bulbWith the LED patch or LED plug-in LED (light emitting diode), series or parallel, driving power supply, making a combined shell lampshade capable of converting electrical energy into visible solid semiconductor devices, which can be directly converted into electricity to light.

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?: L electrode for eutectic solder reflow, the other can be used, regardless of the kind of welding, the temperature is not lower than 100 degrees, the flammable soluble materials have strict requirements, depending on whether the welding temperature is lower than the melting point of what you said or. Otherwise, there will be deformation or damage to the material in the reflow process.

Q: What are the storage requirements of SMT patch LED (LED)?: Keep in storage- the original sealing bag packing in the condition of the <40 C and <90% RH degrees for 12 months, more than the storage period will bake.Please check the leak before opening the packing bagIn opening the sealed bag, should be placed in SMD LED and C 60%RH. < < 30 degrees under the conditions in the above conditions, SMD LED must be in the open package using reflow within 24 hours. If placed more than 24 hours, you need to bake- baked, SMD LED in C + 80 degrees 5 degrees C and <=10%RH relative humidity in the oven for 24 hours? remove the pouch before baking, and do not open the oven door frequently

Q: What is the difference in performance between the LED plug-in and the LED patch?: No difference, because the core of the two is the same, are diode PN junction, but no packaging, the production process is a little different

Q: LED package and LED SMD LED lamp, what is the difference? Will the release agent be used in that part?: Mold release agent is a functional substance between the mold and the finished product. The release agent is chemically resistant and is not soluble in contact with the chemical constituents of different resins (especially styrene and amines). Release agent also has heat and stress properties, not easy to decompose or wear; release agent bonded to the mold, and not transferred to the processed parts, without prejudice to painting or other two processing operations. Because of the rapid development of injection molding, extrusion, calendering, molding and laminating, the dosage of mould release agent is greatly improved.
