Q:LED package and LED SMD LED lamp, what is the difference? Will the release agent be used in that part?
Packaging is for TOP series LED, that is, the type of plastic molding. The patch is based on the PCB circuit board for molding. Mold release agent is used in molding.
Q:What is the difference between patch LED beads and LED beads: General
A LED chip is led lamp. Common LED has two or four pins, and there is no needle foot, close to the circuit board, copper foil welding, are the same. You should choose the lamp the key is to consider the color temperature, color rendering index, light efficiency, light, and power quality, buy these things to buy better quality, common is topclass photoelectric
Q:What determines the brightness of the patch LED?
Lamp brightness level itself, is also in the rated current situation, its brightness
Q:What is the rated current for the white patch LED?
Generally small power LED rated current is basically 20mA
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:How does the LED patch lamp differentiate between positive and negative poles?
You can also use the ohmmeter's ohmmeter. To dial multimeter, to "ohm X1" file, the light emitting diode when the red pen is connected to the positive terminal of SMD LED, the black probe is connected to the negative terminal of SMD LED.
Q:What does "1210" mean in patch LED?
1210 represents the size of the LED package specification (size, specification), and represents the length and width of the resistanceSpeed adoption!!!
Q:Patch LED beads can be bought in what place?
Many LED packaging plants do patch LED, you can find the relevant manufacturers to contact, or go to the local electronic components market according to your needs
Q:Patch LED light broken one, short circuit can use it?
Only when a constant current source is used, the LED in series can be shorted. For the shunt power supply shunt LED, the open circuit LED can be disabled without having to manage it. The short circuit must be removed
Q:What is patch SMD-LED?
Semiconductor wafers consist of two parts, one is P type semiconductor, in which the hole dominates, and the other end is N type semiconductor, which is mainly electronic here. But when the two semiconductors are connected, they form a P-N junction between them. When the current passes through the wire acting on the chip, the electrons are pushed into the P region. In the P region, electrons combine with the hole and then emit energy in the form of photons, which is the principle of LED luminescence. The wavelength of light, that is, the color of light, is determined by the material that forms the P-N junction.
