Q: What is the principle used in SMD LED lamp, should pay attention to what the problem?: LED installation method 1, don't install the LED pin in 2, under the condition of deformation in printed circuit board when installing LED, circuit board hole center distance and LED pin center spacing should be the same, if the hole spacing will make the lamp feet have residual stress and welding...

Q: LED patch lamp band, how to calculate how many watts a meter, such as 3528-60 beads is how much?: LED patch lamp with 3528-60 beads should be 4.8W/ meters.Because the LED light belt is made according to the manufacturer's standard, the parameters are different, and the parameters of the LED lamp belt and the method of use are best connected with the manufacturer's confirmation. Some common parameters are given here for reference only

Q: How does the LED placement lamp distinguish the positive and negative poles? There is no sign on the light. Thank you: You can also use the ohmmeter's ohmmeter. To dial multimeter, to "ohm X1" file, the light emitting diode when the red pen is connected to the positive terminal of SMD LED, the black probe is connected to the negative terminal of SMD LED.

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: Which is good for LED patch and LED bulb?: LED (light emitting diode) patch (package)LED patch (SMD) made by FPC circuit board, LED, high quality silica gel. The waterproof performance, using low voltage DC power supply is safe and convenient, light colors, bright colors; outdoor use can be anti UV aging, yellowing, high temperature resistance and other advantages, the products are widely used in building lights, decorative lighting, advertising - Entertainment decorative lighting lighting field.LED bulbA solid state semiconductor device that converts electric energy into visible light by means of LED (light-emitting diode), which converts electricity directly into light; LED = Large, Electronic, Display,;

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: Patch LED features: The principle of luminescence is that of cold luminescence, not by heating or discharging light, so the component life is about 50~100 times longer than that of tungsten filament bulb, and about one hundred thousand hours.

Q: What is patch LED?: LED is usually the lead pins form, need to be drilled on the printed circuit board, the LED pin is inserted in the hole, welded with wave soldering machine; and the patch type LED is used in welding surface, flat welded on the circuit board.

Q: What is the difference in performance between the LED plug-in and the LED patch?: No difference, because the core of the two is the same, are diode PN junction, but no packaging, the production process is a little different

Q: How do led patches measure good or bad?: The patch LED is also called SMD LED. Its principle of luminescence is to pass the current through the compound semiconductor. Through the combination of the electron and the hole, the excess energy will be released in the form of light to achieve the effect of luminescence.
