Due to the limitation of LED power level, the driving circuit usually needs to drive multiple leds at the same time to meet the brightness requirements. Therefore, a special driving circuit is needed to light the LED. Resistance capacity step-down, using the impedance of capacitor in ac to limit the input current, dc level to power LED.

LED energy saving lamp, the price is too high, LED monomer price, aluminum radiator, efficient constant current power supply, high light transmittance soft lampshade, the four costs collectively push up the cost of LED. Most LED CFLs indicate the total power of the LED chip, rather than the input power of the power supply. LED brightness (MCD) varies in price. LEDs used in LED luminaires shall conform to laser.

From the perspective of pixel structure, the traditional SMD package is basically a pixel; COB packaging is the LED chip directly packaged on the module substrate, and then for each large unit of the overall mold seal, a packaging structure has hundreds of pixels; However, IMD "4-in-1" means that there are four basic pixel structures in a package structure, which is still essentially four "lamp beads" synthesized by 12 RGB-LED chips. "4-in-1" LED module uses the formal chip, with packaging manufacturers to make more requirements on the chip, later may also launch "6 in 1" or even "N in 1" various programs.
