Notes on patch LED
Moisture proof, in order to avoid the products in the transport and storage of moisture, SMD LED packaging is moisture-proof aluminum packaging, and packaging bag containing a desiccant and humidity card, mainly to control the desiccant bag, humidity, humidity card is mainly to monitor the packaging bag of humidity
Patch LED market conditions
Conventional monochrome SMD LED package sizes are 1206 (3215), 1004 (2510), 0805 (2012) and 0603 (1608). Chinese manufacturers can provide a minimum size of 0603, the thickness of only 0.3 mm. A smaller LED of 0402 (1005) is still in trial manufacture
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.
How to detect LED SMD beads
The output voltage of the digital clock diode file is not high, generally below 2.5V, so the measurement of LED lamp does not work, the best way is to external electrical measurement. If there are a lot of beads to measure it, can take a constant current power measurement.
How does the LED placement lamp distinguish the positive and negative poles? There is no sign on the light. Thank you
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.
What determines the brightness of the patch LED?
The brightness is consistent over a short period of time, that is, only by considering current and voltage consistency.Long term brightness is consistent with the consideration of the spacing and heat dissipation of different circuits. Uneven heat can also affect brightness.
Does anyone know what the current rating of a white high brightness LED patch is? Where can I find out?
The high power 1W is 350MA, and 3W is 700MA. They are all fixed and can be found everywhere.
What are the storage requirements of SMT patch LED (LED)?
Clean? use no designated chemical liquids to clean SMD LED. These chemicals may damage SMD LED.. When necessary, wipe LED at room temperature with alcohol and dry at room temperature for 15 minutes before use? the effect of ultrasonic cleaning on SMD LED is related to the ultrasonic power and the SMD LED assembly method, and shall be checked in advance to ensure that the ultrasonic cleaning process does not impair the SMD LED
