Therefore, good heat dissipation is the guarantee for the LED to maintain constant brightness. Therefore, the use of constant voltage source drive cannot guarantee the consistency of LED brightness, and affect the reliability, life and light decay of LED. Therefore, ultra-bright leds are usually driven by constant current sources.

LED voltage, this refers to the LED lamp with the input voltage, the commonly used specification is DC 12V, also have some 24V. LED shortcomings, LED energy-saving lamps, the need for the corresponding radiator, in the case of LED chip itself heat without a big improvement, the need for the structure of the radiator, heat pipe technology application, further development.

Finally, electrical interconnection between the chip and PCB board is realized by connecting the lead wire (gold wire). The LED crystal is fixed on the front surface of the display substrate, and the film is pasted on the front surface of the display substrate. The LED crystal is a common red, green and blue LED light-emitting chip to realize integrated packaging. Integration of Economy and Technology -IMD Process, At present, IMD process is still using the surface paste process, combined with the advantages of SMD and COB.
