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?
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:LED package and LED SMD LED lamp, what is the difference? Will the release agent be used in that part?
Packaging is for TOP series LED, that is, the type of plastic molding. The patch is based on the PCB circuit board for molding. Mold release agent is used in molding.
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: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:How to detect LED SMD beads
Now the LED lamp, drop it in general about 3V, so the general multimeter is not measuring it.
Q:Indoor full color LED display module and LED what is the difference between a full color?
(1): LED full color light emitting module display module is generally yellow green, pure green module price is more expensive; SMD full color LED display using pure green tube coreThe display module (2): LED full color pixel visual feeling is thick, low brightness, easy to have the mosaic phenomenon; patch LED full color consistent, high brightness;(3): maintenance module LED full color display is not easy to maintain, the whole module replacement cost is high; SMD full-color LED screen for easy maintenance, repair and replacement of single lamp;
Q:Patch LED market conditions
Patch LED (SMD LED) is mainly used in lighting systems, decoration, electronic equipment, indicators, backlight, monitors and instruments and other fields. The decline in handset and LCD TV production in 2009 could affect the supply expectations for such components.
Q:What does "1210" mean in patch LED?
1210 refers to the lamp specifications.LED common lamp specifications and parameters of patch0603, 0805, 1210, 3528, 5050 refers to the LED lamp belt, often used in light-emitting components ----LED size (English / Metric) name, for example, 0603 refers to the length of 0.06 inches, width of 0.03 inches. But note that the 3528 and 5050 units are metric
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
