- 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: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: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.
- Q:Patch LED light does not flash, why?
- Hit the meter on the buzzer and measure the patch individually. If the flash is a patch, the light goes off.
- 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 do led patches measure good or bad?
- Use the two stage tube test of the multimeter, the red pen is connected, and the black pen is negative. If there is a bee, the sound is bad, and if the light is bright, it is good
- Q:Notes on patch LED
- Storage bags are sealed and stored at a temperature of <40 DEG C.
- 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:What does "1210" mean in patch LED?
- At present, most manufacturers of SMD light strip used by 3528 and 5050, and 3535 and 5630 in the majority, there are many of the 3528 and 5050 and 3535, such as patch LED used in automotive lighting.
- 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
