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:What determines the brightness of the patch LED?
The current through the lamp itself. If the same lamp, so it is necessary to ensure consistency in the different current circuit, the test voltage of little significance, especially in the case of parallel lamp, current a few beads each share is not the same, some big, some small.
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:Why is the patch LED blue light dim?
The pressure drop of the blue light is greater than that of the red light and the green light. If the series connection is the same as that of the green light and red light, the current limiting resistor will tend to dim
Q:SMD LED specification
SMD LED specification:(1) metal stent type: 0402, 0603, 0805, 1206, 3mm, 5mm, 6mm, 8mm, 10mm and so on.(2) metal support (commonly known as small butterfly) type: 2mm, 3mm and so on.(3) TOP LED (white shell) type: 1208 (30*20), 1311 (35*28), 1312 (35*32), 2220 (55*50) and so on(4) side light LED:0905 (22*12), 1105 (28*12) 1605 (40*14) and so on.
Q:LED patch lamp band, how to calculate how many watts a meter, such as 3528-60 beads is how much?
3528-60 is 60 meters per lamp, 3528 SMD lamp with no 5050 light, about 10 watts per meter. Copper wires have less resistance and may be less than 10 watts per meter.
Q:How many voltages and how many W drivers are used in series and parallel connection with 20 1W patches LED?
The voltage problem is determined by the size of your POWER SUPPLY, according to Ohm's Law: the series voltage is accumulated and the shunt voltage is the same.
Q:Patch LED light does not flash, why?
Light emitting diodes, referred to as LED. Made from compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N) and so on.When electrons and holes are combined, they can radiate visible light, so they can be used to make light-emitting diodes. In circuits and instruments, as an indicator, or in combination with text or digital display. GaAs diodes glow diode gap, green silicon carbide, yellow light diode, light emitting diode gan. Because of the chemical properties and organic light-emitting diode OLED and inorganic light-emitting diode LED.
Q:The quality of the LED patch module
Quality of circuit board. In the same quality of LED, the quality of PCB will have an important impact on the life of LED. The circuit board is divided into aluminum plate, glass fiber board, semi glass fiber board and paperboard. The quality of aluminum is the best, the best cooling effect, but the cost is too high, the domestic manufacturers generally only in high-power LED products use, LED module manufacturers generally use cardboard, semi glass fiber and glass fiber board. Module, piranha, straw hat module monochrome is generally used in cardboard or semi glass, commonly used glass fiber or semi SMD glass fiber board. Colorful and full color module series generally at least half of glass fiber, so as to match.
Q:What is the difference between patch LED beads and LED beads: General
A pin of the lamp, and outside a resin cap, because the reason LED beads can spotlight cap;There is no pin on the patch and there is no resin cap outside. Because of the lack of cap, the LED patch can not be concentrated.LED patch lamp is made of FPC circuit board, LED lamp and high quality silica gel sleeve. 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 and entertainment quasi decorative lighting lighting field.
