- Q: What determines the brightness of the patch LED?
- The brightness is consistent over a short period of time, that is, only by considering current and voltage consistency.Long term brightness is consistent with the consideration of the spacing and heat dissipation of different circuits. Uneven heat can also affect brightness.
- 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: What, in what way do I shunt the 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: What is patch SMD-LED?
- SMD LED is the surface mount light emitting diode. It is a solid state semiconductor device that converts electricity directly into light. The heart of LED is a semiconductor wafer, one end of which is attached to a bracket, one end is negative, and the other is connected to the positive electrode of the power to encapsulate the entire wafer with epoxy resin.
- 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: 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?
- L electrode for eutectic solder reflow, the other can be used, regardless of the kind of welding, the temperature is not lower than 100 degrees, the flammable soluble materials have strict requirements, depending on whether the welding temperature is lower than the melting point of what you said or. Otherwise, there will be deformation or damage to the material in the reflow process.
- 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.
- Q: Patch LED light broken one, short circuit can use it?
- Only when a constant current source is used, the LED in series can be shorted. For the shunt power supply shunt LED, the open circuit LED can be disabled without having to manage it. The short circuit must be removed
- Q: How do led patches measure good or bad?
- Use the two stage tube test of the multimeter, the red pen is connected, and the black pen is negative. If there is a bee, the sound is bad, and if the light is bright, it is good
- 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.
