About MJT 1. Simplify the circuit to improve efficiency and significantly reduce system cost. 2. There is no need for gold wire electrical connection between LED P/N junctions to avoid various quality problems such as popcorn effect. 3. It is very effective for applications with size limitation, for example Minimize circuit up to 30% of A19 bulb applications 4. Multi-voltage applicability of only one chip 5. LED juncTIon number can be optimized according to voltage and efficiency requirements 6. Easy to design applications from AC to DC operation 7. Cost comparison for 8w bulbs with an efficiency of 88% - 100mA DC LED for 8W applications: 28 chips + power supply - 20mA for 8W applications MJT LED: 21 chips + power supply (30% component reduction) The MJT5630 is a high-voltage SMD LED developed using multi-junction technology with a package size of 5.6x3.0x0.75mm. 460lm bulb application recommendations: Outer ring 8pcs, spacing 32mm; inner ring 4pcs, spacing 17mm MJT LED drive method 1 (LDO type) MJT LED drive method 2 (buck type) 1) Reflective cup must use high reflective material, the reflectivity must be greater than 95% Shenzhen Scodeno Technology Co.,Ltd , https://www.scodenonet.com
MJT is a multi-P/N junction technology that has a higher driving voltage than conventional LEDs. The high-voltage LEDs on the market are actually many LED chips connected in series and in parallel, and the circuit design is complicated. MJT uses multiple juncTIon technologies to be integrated in the same chip to obtain different voltage values. 
Fewer LEDs - simplified circuit - smaller size - lower cost
