Q:What does patch LED light mean?
The patch may be said, adding that the patch board PCB light source, light source lamp light source generally refers to, patch may refer to the combination of PCB plate and two lens beads.
Q:Is the forward voltage drop of the patch LED too large or too small?
Pressure drop does not mean good or bad, the greater the pressure drop, the better to choose the right for you
Q:How to install the patch LED lamp band?
More attention is paid to the lamp with waterproof and the installation of a solid in the outdoor installation, outdoor installation often adopts the mode of fixed card slot, need to cut and connected place, and indoor installation, just need another with waterproof glue, waterproof effect to consolidate the connection point.
Q:SMD LED lamp working voltage?
LED is a light emitting device of low voltage, low current, low power forward current general patch type LED when using (IF) 20MA, (VF) 1.8-2.5V, voltage of red green and blue (VF) voltage is 3.0-3.6V. Different manufacturers also have small differences, so first of all, look at the color,Of course. The multi chip assembly in high voltage chip together, some current: 1 watts, 1 watts and above. A wide variety of varieties, as follows:
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:How do led patches measure good or bad?
LED patch how to measure methods: use two meter meter test, red pen is positive, black pen negative, if there is "bee" sound is bad, if the light is good
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:Notes on patch LED
Storage bags are sealed and stored at a temperature of <40 DEG C.
Q:LED patch lamp band, how to calculate how many watts a meter, such as 3528-60 beads is how much?
LED patch lamp with 3528-60 beads should be 4.8W/ meters.Because the LED light belt is made according to the manufacturer's standard, the parameters are different, and the parameters of the LED lamp belt and the method of use are best connected with the manufacturer's confirmation. Some common parameters are given here for reference only
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?
SMD patch products basically can be used in reflow soldering, especially a little note here that the eutectic welding is the connection between the chip and the substrate support or specifically, is the bottom of the chip after completion of production of coating material and a layer of Sikkim alloy, and then set up a heating zone in solid crystal machine package in time and a temperature of about 300 degrees, the realization process of the chip at the bottom of the Sikkim alloy melt and silver plated layer connection bracket, and a clear distinction between reflow.
