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?
Chip and stent welding methods are: eutectic welding, silver glue fixed, resin insulation and fixed silicone rubber insulation fixedWelding beads: reflow soldering, hot plate welding and manual soldering.
Q:SMD LED specification
LED patch: 0603, 0805, 1206, 1210, 5050. The 0603: conversion to metric is 1005, that of the LED element length is 1.0mm, width is 0.5mm. The trade is abbreviated as 1005, and the English name is 0603. The 0805: conversion to metric is 2125, that of the LED element length is 2.0mm, width is referred to as the 2125 inch 1.25mm. industry, it is 0805. The 1206: conversion to metric is 3216, that of the LED element length is 3.2mm, width is 1.6mm. The trade is abbreviated as 3216, and the English name is 1206. The 1210: conversion to metric is 3528, that of the LED element length is 3.5mm, width is 2.8mm. The trade is abbreviated as 3528, and the English name is 1210. The 5050: This is a metric called, said that the LED element length is 5.0mm, width is 5.0mm. Industry abbreviation 5050
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.
Q:Patch LED manual welding, how can welding not burn lights?
First of all, welding LED and other electronic products with line electrostatic ring, to prevent static light.When welding the patch LED lamp, first add the tin on the pad of the lamp board, then clamp the LED patch lamp with tweezers. Then, the soldering iron will melt the tin of the solder plate of your lamp board, and then push the LED lamp onto the pad with tweezers. The whole welding process should not exceed 5 seconds, otherwise it will burn the lamp easily.
Q:Patch LED market conditions
Conventional monochrome SMD LED package sizes are 1206 (3215), 1004 (2510), 0805 (2012) and 0603 (1608). Chinese manufacturers can provide a minimum size of 0603, the thickness of only 0.3 mm. A smaller LED of 0402 (1005) is still in trial manufacture
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: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:How does the LED patch lamp differentiate between positive and negative poles?
The light emitting diode is fixed regardless of color. The light emitting diode 1, line: foot length is positive, the negative is short. The electrodes inside the tube can also be carefully observed, while the smaller ones are positive and the large ones, similar to the bowl, are negative. 2, SMD: overlooking the side with the color line is negative, the other side is positive.
Q:LED patch lamp band, how to calculate how many watts a meter, such as 3528-60 beads is how much?
3528 single lamp is 0.06W 0.06*60 lamp =3.6W 3528-60 bead is 3.6W/ meters
Q:Led lamp and Led what is the difference between the two patch! Ask for detailed explanations of the differences!
If you take a large area light, to see that the lighting requirements, functional lighting, or lighting atmosphere, or ordinary lighting, which is to be considered, the two optical (lens) can bring you the light angle planning.
