- 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:What determines the brightness of the patch LED?
- Lamp brightness level itself, is also in the rated current situation, its brightness
- Q:What is the rated current for the white patch LED?
- LED high power and low power, small white rated current and LED wafer, such as a chip is 20MA two 40MA.... High power 0.5W, 100-150MA, 1W, 350MA current rating in the relevant product specifications
- Q:How many volts is a single LED on the LED patch band?
- The single LED on the LED patch band is around 3.3V.LED light emitting diode, which is a nonlinear component, its operating voltage (tube pressure drop) is also different: ordinary red LED about 1.5 V; ordinary green LED about 1.8 V; bright white LED up to 3.3 V or so.
- 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:What is patch LED?
- Patch element. Very small, no pins, soldered directly to the circuit board. For example, the keyboard lights in a mobile phone are used in this way.
- Q:Patch LED beads can be bought in what place?
- SMD LED lamp is now very popular, mainly because of long service life, but also rarely appear dead lights or dark, but there are many defects exist
- Q:Patch LED manual welding, how can welding not burn lights?
- If the power of the lamp, because heat high power do very well, so not good welding, the temperature at the highest (300 degrees), the use of horseshoe iron head, not waiting to solder, because the heat is very powerful, quick action.
- 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:Notes on patch LED
- Storage bags are sealed and stored at a temperature of <40 DEG C.
