Q:What is the rated current for the white patch LED?
The high power 1W is 350MA, and 3W is 700MA. They are all fixed and can be found everywhere.
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:SMD LED lamp working voltage?
Voltage range of white LED lamp: 3.0-3.4VThe pressure drop of the red LED is 2.0--2.2VThe yellow light emitting diode has a pressure drop of 1.8 - 2.0VThe green light emitting diode has a pressure drop of 3 - 3.2VThe blue light emitting diode has a pressure drop of 3.0-3.4VSMD voltage is basically the same as double lead line. Current is generally 20~60mA, and some work current can exceed 100mA.
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:What determines the brightness of the patch LED?
The current through the lamp itself. If the same lamp, so it is necessary to ensure consistency in the different current circuit, the test voltage of little significance, especially in the case of parallel lamp, current a few beads each share is not the same, some big, some small.
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.
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?
In series, the voltage is 20 times the rated voltage, in parallel, the voltage is rated voltage, but in tandem, a LED is broken, it is not bright, so it is recommended not to use it.
Q:Indoor full color LED display module and LED what is the difference between a full color?
The classification of the LED display according to the installation environment: indoor LED display screen, semi outdoor LED display, outdoor LED display; according to color: color LED screen, dual color LED display screen, LED display screen, the color LED display screen; according to the functional area can be divided into graphic screen, screen, screen, screen, digital dot matrix digital hybrid screen.
Q:The quality of the LED patch module
Chip manufacturers, the top chip mainly from the United States, Germany, Japan and South Korea and so on. But on the mainland LED module manufacturers to use the vast majority of chip from Taiwan, of course, there are a lot of use of chip, market positioning, the main users of the product features with the manufacturers and government policies, different chip manufacturers are different its stable performance. Maybe you will ask why not CREE, OSRAM, Nichia, first of the world's top chip manufacturers have fixed target market positioning, such as defense orders, and said, specially import a little CREE chip manufacturing module, it is also not cost-effective; and if the driver is not supporting the raw materials, it can not be completely play the advantage, so is also a great waste.
