Detailed Seoul semiconductor Acrich MJT LED innovative solutions

About MJT

MJT is a multi P / N junction technology, and its drive voltage is higher than the conventional LED drive voltage. The high voltage LED on the market is actually a series of LED chips, which are connected in parallel, and the circuit design is complex. MJT uses the multi junction technology in the same chip, so as to get different voltage values.

MJT advantage

1 simplify the circuit to improve efficiency, significantly reduce the cost of the system

2.LED P/N junction does not require gold wire connection, to avoid the effects of various quality problems such as popcorn

3 for the size of the application is very effective, for example, to minimize the frequency of 30% A19 bubble application

4 only a variety of 1 chip voltage applicability

The number of 5.LED junction can be optimized according to the voltage and efficiency requirements

6 easy to design applications from AC to DC operation

7 Comparison of the efficiency of the application of 8W bulbs in 88%

8W application 100mA DC LED:28 chip + power supply

8W application 20mA MJT LED:21 chip + power supply (30% component reduction)

Fewer LED - circuit simplification - smaller size - lower cost

Introduction to MJT5630 lighting solutions

MJT5630 is the use of multi junction technology developed from the high voltage patch LED, packaging size of 5.6x3.0x0.75mm.
