Q:Welding method and notice of SMT LED
It is best to use a hot-air gun heat transfer high air volume adjustable low moment welding, the specific heat jump to the appropriate place to see what you use what kind of welding wire, welding wire of different because of the different melting point impurities also some differences. The air volume is too high, easy to blow the original
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:SMD LED specification
The patch LED is also called SMD LED. Its principle of luminescence is to pass the current through the compound semiconductor. Through the combination of the electron and the hole, the excess energy will be released in the form of light to achieve the effect of luminescence.
Q:The quality of the LED patch module
Luminous efficiency。 The LM value per watt is called luminous efficiency. This is an important criterion for judging whether LED is energy-saving or not. The incandescent lamp is about 14.4LM/W, the fluorescent lamp is about 51LM/W, the neon lamp is 43LM/W or so, and the LED is up to 150LM/W at present, but most of the LED light effects in our country are in 60~100LM/W. It should be noted that only the white light can achieve such high luminous efficiency in LED, and that red, yellow and blue are generally relatively low (mainly related to human visual definition). But compared with neon light, there is no heavy metal pollution, easy to maintain.
Q:How to install the patch LED lamp band?
Installed indoors, you can directly tear off the stickers on the 3M double-sided adhesive surface, and then fix the light bar where it needs to be installed. Just press it with your hands.
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: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:What is patch LED?
LED lights, a common model, has 34654635285050 piranha.The most common assembly of lights and PCB boards is the DIP, that is, dual in line and SMT surface mount technology two.The 346546 is the LED with two positive and negative pins, which are inserted into the PCB board after cutting the foot;3528 and 5050 are a cube with 3 LED lights inside, known as the "three in one" LED lamp. It has no pin underneath, but has a metal patch that can be passed through the reflow soldering machine through the solder to the PCB board.General indoor LED screen with more patches, outdoor screen with more pins.
Q:What determines the brightness of the patch LED?
Lamp brightness level itself, is also in the rated current situation, its brightness
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
