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?
Chip and stent welding methods are: eutectic welding, silver glue fixed, resin insulation and fixed silicone rubber insulation fixedWelding beads: reflow soldering, hot plate welding and manual soldering.
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: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: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?
Recommend to communicate with older employees, they will have a lot of welding experience
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:Indoor full color LED display module and LED what is the difference between a full color?
(1): LED full color light emitting module display module is generally yellow green, pure green module price is more expensive; SMD full color LED display using pure green tube coreThe display module (2): LED full color pixel visual feeling is thick, low brightness, easy to have the mosaic phenomenon; patch LED full color consistent, high brightness;(3): maintenance module LED full color display is not easy to maintain, the whole module replacement cost is high; SMD full-color LED screen for easy maintenance, repair and replacement of single lamp;
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: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:Led lamp and Led what is the difference between the two patch! Ask for detailed explanations of the differences!
First of all, I want to say, in the same light emitting chip case, two is not what were, just a different process is a DIP plugin, a SMD patch process, the 3 floor of the right, just some high grade patch.
