Q:What does "1210" mean in patch LED?

1210 represents the size of the LED package specification (size, specification), and represents the length and width of the resistanceSpeed adoption!!!

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 light broken one, short circuit can use it?

Can not casually short-circuit, according to the LED connection, but also to see the power supply voltage and current, all the LED can not flow. Any short circuit may cause excess LED to flow over or over, causing a chain reaction, a bad string,...... .

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: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?

When making a batch of LED lights, the brightness values of various lights are in accordance with certain rules. Due to achieve a white balance, three RGB color brightness required by the ratio of 3:6:1, that is to say the blue light required brightness is very low.

Q:SMD LED lamp working voltage?

Single chip of 1 watts, more than a lot, different colors, the voltage will be different. White is usually 3.0-3.6V.* in addition to their working voltage, working current is more important parameters, once the flow, it will burn out.The LED lamp. With chips is variety, many tricks, they can be connected in series and parallel. The voltage is divided into high voltage, low voltage and medium voltage

Q:What should I notice when I want to solder 1206 LED patch type luminous tube on fine copper wire?,

I recommend reflow soldering under normal conditions and manual welding only when repaired. 2 manual soldering electric soldering iron maximum power can not exceed 30W, welding temperature is controlled within 300 degrees, welding time less than 3 seconds. 3 do not touch the colloidal iron welding head. 4 when the pin is heated to 85 degrees centigrade or higher than this temperature, it can not be pressed. Otherwise, the welding will be broken.

Q:LED light SMD LED package in what form, trouble you under the guidance of...

The LED chip has bumps and is welded to the PCB board using FLIP CHIP to packaging technology.LED is English light emitting diode (light emitting diode) abbreviation, its basic structure is a electroluminescent semiconductor chip light emitting materials, with silver glue or glue curing to the bracket, connecting a chip and a circuit board and then with silver or gold, then sealed with epoxy resin around, to protect the internal core role finally, the installation shell, so the seismic performance of LED lamp is good. Field of application involves mobile phones, desk lamps, household appliances and other daily household electrical appliances and machinery production.

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
