Q:Is the forward voltage drop of the patch LED too large or too small?
Pressure drop does not mean good or bad, the greater the pressure drop, the better to choose the right for you
Q:SMD LED lamp working voltage?
Single chip of 1 watts, more than a lot, different colors, the voltage will be different. White is usually 3.0-3.6V.* in addition to their working voltage, working current is more important parameters, once the flow, it will burn out.The LED lamp. With chips is variety, many tricks, they can be connected in series and parallel. The voltage is divided into high voltage, low voltage and medium voltage
Q:Why is the patch LED blue light dim?
When making a batch of LED lights, the brightness values of various lights are in accordance with certain rules. Due to achieve a white balance, three RGB color brightness required by the ratio of 3:6:1, that is to say the blue light required brightness is very low.
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:LED light SMD LED package in what form, trouble you under the guidance of...
The LED chip has bumps and is welded to the PCB board using FLIP CHIP to packaging technology.LED is English light emitting diode (light emitting diode) abbreviation, its basic structure is a electroluminescent semiconductor chip light emitting materials, with silver glue or glue curing to the bracket, connecting a chip and a circuit board and then with silver or gold, then sealed with epoxy resin around, to protect the internal core role finally, the installation shell, so the seismic performance of LED lamp is good. Field of application involves mobile phones, desk lamps, household appliances and other daily household electrical appliances and machinery production.
Q:What are the storage requirements of SMT patch LED (LED)?
Keep in storage- the original sealing bag packing in the condition of the <40 C and <90% RH degrees for 12 months, more than the storage period will bake.Please check the leak before opening the packing bagIn opening the sealed bag, should be placed in SMD LED and C 60%RH. < < 30 degrees under the conditions in the above conditions, SMD LED must be in the open package using reflow within 24 hours. If placed more than 24 hours, you need to bake- baked, SMD LED in C + 80 degrees 5 degrees C and <=10%RH relative humidity in the oven for 24 hours• remove the pouch before baking, and do not open the oven door frequently
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: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.
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?
In series, the voltage is 20 times the rated voltage, in parallel, the voltage is rated voltage, but in tandem, a LED is broken, it is not bright, so it is recommended not to use it.
