- 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.
- Q:Patch LED features
- The seismic resistance, high reliability, low operation cost system.It is easy to small, thin, lightweight, easy to shape without restrictions, made all kinds of application.
- Q:How does the LED patch lamp differentiate between positive and negative poles?
- Because the LED open threshold is about 1.5-1.8V. It is possible that the voltage supplied by the digital multimeter does not activate it. So look at the sign. Patch LED (SMD LED), the green point of negative, relative to the positive.
- 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: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: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: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:Patch LED light broken one, short circuit can use it?
- Patch LED lamp LED wick is usually series, and a bad, can temporarily short-circuit, temporary use, because after short-circuit, this LED wick voltage will be assessed to other LED wick, accelerate other LED wick aging.The damaged LED wick needs to be secured as soon as possible.
- Q:Notes on patch LED
- Clean, do not use an unknown chemical liquid to clean the patch LED: an unknown chemical liquid may damage the patch LED. When necessary, immerse the patch LED in alcohol, less than 1 minutes at normal room temperature, and dry naturally for 15 minutes before starting to use
- Q:How many voltages and how many W drivers are used in series and parallel connection with 20 1W patches LED?
- The voltage problem is determined by the size of your POWER SUPPLY, according to Ohm's Law: the series voltage is accumulated and the shunt voltage is the same.
