attention & cautions

 

1. Over-current-proof

Customer must apply resistors for protection; otherwise slight voltage shift will cause big current change (Burn out will happen). 

 

2.  Storage

 

2.1 It is recommended to store the  products in the following conditions 

Humidity: 60% R.H. Max. 

Temperature: 5°C~30°C(41°F~86°F)  

 

2.2  Shelf life in sealed bag: 12 month at  <5°C~30°C and <30% R.H. after the package   is opened,

the products should be used within 24hr s or they should be kept stored at<20% R.H. with zip-lock sealed.

 

3. Vision Advisory Claim

 

Users should be cautioned not to stare at the light of this LED product. The bright light can damage the eye.

Q:What does patch LED light mean?
The screen is divided into standard lamp and patch type, the light emitting diode lamp is inserted into the circuit board, and the patch is a patch welded on the circuit board. Two light sources are not the same. If only light, not so clear.
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 patch lamp band, how to calculate how many watts a meter, such as 3528-60 beads is how much?
3528 single lamp is 0.06W 0.06*60 lamp =3.6W 3528-60 bead is 3.6W/ meters
Q:What are the storage requirements of SMT patch LED (LED)?
Moisture-proof packing- anti SMD LED in the transport and storage of moisture absorption, SMD LED shall be placed in sealed moisture-proof bag, inside put damp proof agent for protection, and placed the humidity humidity SMD display card packaging bag.
Q:Patch LED light does not flash, why?
Are you saying that lamp is flashing? You can check the power output, according to your standard parameters and SMD beads, lamp panel series parallel mode, calculate the power output to output power of the test, you may be wrong, power, overload, but also the effective part of you may be the circuit for power transmission is not stable or low
Q: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.
Q: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
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.
Q:Patch LED light broken one, short circuit can use it?
Patch LED lamp LED wick is usually series, and a bad, can temporarily short-circuit, temporary use, because after short-circuit, this LED wick voltage will be assessed to other LED wick, accelerate other LED wick aging.The damaged LED wick needs to be secured as soon as possible.
Q:Patch LED manual welding, how can welding not burn lights?
First of all, welding LED and other electronic products with line electrostatic ring, to prevent static light.When welding the patch LED lamp, first add the tin on the pad of the lamp board, then clamp the LED patch lamp with tweezers. Then, the soldering iron will melt the tin of the solder plate of your lamp board, and then push the LED lamp onto the pad with tweezers. The whole welding process should not exceed 5 seconds, otherwise it will burn the lamp easily.
