 Application notes

 A) The LEDs should be kept at 30°C or less and 90@ RH or less. The LEDs should be used within a year. When storing the LEDs, moisture proof packing with absorbent material(sillica gel) is recommended.

 B) The LEDs should be kept at 30°C or less and 70%RH or less. The LEDs should be soldred within 24 hours(1days) after opening the package. If unused LEDs remain, they should be stored in moisture proof packages, such as sealed containers with packages of moisture absorbent material(sillica gel). It is also recommennded to return the LEDs to the original moisture proof bag and to reseal the moisture proof bag again or it need to rebake before using next time.



Baking condition:temperature 70°C±5°C;humidity:less than 10%RH

Q:What does patch LED light mean?
Look, what's your product?. Some products have volume requirements, straight line will be relatively large, patches of small affixed to the circuit board does not occupy space, if only the light source, it may be an ordinary light bulb, as LED power saving.
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
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: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: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:Indoor full color LED display module and LED what is the difference between a full color?
Indoor full color LED display module and LED chip has three full color difference. The first part: Second: third light emitting display module: maintenance: LED full color display is not easy to maintain. LED full color patch is relatively easy to maintain.
Q:The quality of the LED patch module
Life。 LED's life is considered 100000H. In fact, LED products in 10 or 20 years to reach 100000 hours, and now the best LED life expectancy is only 50000 hours. Incandescent lamp for 1000 hours, fluorescent lamp for 2000 hours, neon for 10000 hours. The so-called "100 thousand hours" was only measured by scientists at room temperature at room temperature. After the formation of LED and chip packaging products, even the top of the chip, due to differences in the production of advanced packaging using the equipment, technical differences, the different forms of packaging, management, as well as the difference between the way users, resulting in life are not the same. Patch LED, life can reach 40000-50000 hours; piranha LED, life expectancy of 30000 hours, inline LED, life expectancy is 10000 hours. Of course, with the advances in chip and packaging technology, these data will gradually increase. The premise is that you understand an important concept, LED life means when the brightness of LED is 70% of the original brightness, we decide the LED life to this end.
Q:Patch LED market conditions
With good market expectations for the future status of SMD LED, all the major manufacturers have launched their own SMD LED development planning and prototype products, all of a sudden, SMD LED market showing a flourishing and lively atmosphere of contention of a hundred schools of thought.
Q:Notes on patch LED
Storage bags are sealed and stored at a temperature of <40 DEG C.
Q:Patch LED features
The principle of luminescence is that of cold luminescence, not by heating or discharging light, so the component life is about 50~100 times longer than that of tungsten filament bulb, and about one hundred thousand hours.
