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:What is the difference between SMT LED packaging with silicone and epoxy resin transparent package? What is the market situation of these two types of packaging?
At present, it is basically made of silica gel, and the epoxy resin is very few. Only those with lower price may use some. Why is it rare to use epoxy? Because of the use of LED epoxy patch cited some discomfort because the cable used in the above: reflow welding, high temperature resistant epoxy epoxy and silicone not lead to separation, produce decay dead lights etc..
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: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: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: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: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?
1210 represents the size of the LED package specification (size, specification), and represents the length and width of the resistanceSpeed adoption!!!
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
Q:Patch LED features
The seismic resistance, high reliability, low operation cost system.It is easy to small, thin, lightweight, easy to shape without restrictions, made all kinds of application.
