FAQ

What is the principle used in SMD LED lamp, should pay attention to what the problem?
LED white is the light emitting diode, a PN junction to the most important use of SMD beads is the heat, according to the different manufacturer beads, glue package is not the same, should pay attention to pre baking time and temperature, the latter should pay attention to the patch temperature, the most important is the price, many manufacturers in order to cost savings, internal chip used is too small does not meet the standards, support steal frugal material, with iron, the failure cycle shortened, LED lamp can not reach the ideal effect. Again, the LED supply current must not exceed the rated value, which is an important factor in damage to lamps and lanternss
SMD LED lamp working voltage?
18 volts driven high 3030LED lamp (six core series, and 2 core, 3 core series and Design), driving power of up to 1W,1W high voltage 3030 LED (3 volts, 6 volts, 9 volts, 18 volts optional)s
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.s
What determines the brightness of the patch LED?
Lamp brightness level itself, is also in the rated current situation, its brightnesss
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.s
Notes on patch LED
Storage bags are sealed and stored at a temperature of <40 DEG C.s
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 photoelectrics
Patch LED features
Without heating time, lighting is faster than general light (about 3 ~ 400ns).The electro optic conversion efficiency is high, the power consumption is small, and the energy consumption is about 1/3 ~ 1/20 than that of the bulb.s
