Q:What is the principle used in SMD LED lamp, should pay attention to what the problem?
Table 1, contact electrostatic protection LED product should be covered with protective electric tape, and its reliable grounding; 2, personnel shall wear groundstrap in contact with LED (best for cable, protective gloves, anti-static ring) allows better wear anti-static clothing, anti-static shoes and static electricity cap; 3, the application in the process of exposure to LED equipment must be reliable grounding, such as iron, shearing machine, bending machine and welding equipment. Conditional still can install plasma fan to eliminate electrostatic; 4, in use or when designing electronic circuit, must consider the harm that excessive current has to LED
Q:The ten patch LED lights are connected in parallel. The rated power is 5 watts. How much voltage do you need?
The voltage needs to be determined according to the product specification, usually 3.1 - 3.5V
Q:Which is good for LED patch and LED bulb?
Chip LEDLED patch lamp (SMD) 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.LED bulbThe light emitting diode, is capable of converting electrical energy into visible solid semiconductor devices, which can be directly converted into electricity to light; LED Large Electronic = Display, LED = large electronic display; Lupus erythematosus disseminatus, systemic lupus erythematosus, a chronic idiopathic autoimmune disease; LED lead the past and past participle, meaning "leadership, led the Russian Pulkovo Airport IATA code.
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:How to install the patch LED lamp band?
More attention is paid to the lamp with waterproof and the installation of a solid in the outdoor installation, outdoor installation often adopts the mode of fixed card slot, need to cut and connected place, and indoor installation, just need another with waterproof glue, waterproof effect to consolidate the connection point.
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:Why is the patch LED blue light dim?
If you choose the brightness of blue light in the light of the relatively high, so when debugging the white balance (by changing the resistance to change the current, and then change the RGB brightness LED lamp), it is difficult to transfer to the pure white. Therefore, when selecting the lamp, the blue light is generally not bright.
Q:Patch LED market conditions
Patch LED (SMD LED) is mainly used in lighting systems, decoration, electronic equipment, indicators, backlight, monitors and instruments and other fields. The decline in handset and LCD TV production in 2009 could affect the supply expectations for such components.
Q:Patch LED light does not flash, why?
There are three main reasons:1, the temperature is too high, resulting in LED lights, dead lights.2, do not do anti-static measures, electrostatic breakdown chip, resulting in damage to the LED light.3, the use of LED lamp quality is too bad, the purchase price reasonable LED lights
Q:Notes on patch LED
Clean, do not use an unknown chemical liquid to clean the patch LED: an unknown chemical liquid may damage the patch LED. When necessary, immerse the patch LED in alcohol, less than 1 minutes at normal room temperature, and dry naturally for 15 minutes before starting to use
