EKINGLUX was founded in Shenzhen in 2005. In order to meet the company's development needs, the company established Dongguan EKINGLUX Optoelectronics Technology Co., Ltd. in Dongguan in 2013. At the end of 2019, it moved to Huayuan Industrial Zone, Xiegang Town, Dongguan City, with a production and operation area of 15,000 square meters. EKINGLUX aims to build a world famous brand in China, strives hard and keeps making progress. In May 2014, EKINGLUX passed the ISO9001 quality system certification, in 2015, it was awarded a high-tech enterprise in Guangdong Province, and in August 2017, it passed the TS16949 certification in the automotive industry. In January 2018, it obtained the intellectual property management system certificate, and EKINGLUX has successively become the vice president unit of China LED Optoelectronics Association.
Over the years, EKINGLUX has always put quality and reputation in the first place, adhered to the business tenet of "market-oriented, customer-centered, talent-based, and quality-oriented", and attached great importance to the research and development of new products and new technologies. The application provides a reliable guarantee for the ultimate realization of customer goals and the creation of value for customers. As an LED manufacturer with high production efficiency, complete equipment, strict management, sincerity and professionalism, and good reputation, professional product research and development, excellent team cohesion, all-round market development and high-quality corporate culture make EKINGLUX a domestic leader. One of the most competitive companies in the industry.
Common specifications and models of LED chips
0603, 0805, 1210, 3528, 5050 refer to the size of surface mount SMD LEDs. For example, 0603 refers to a length of 0.06 inches and a width of 0.03 inches. But note that the 3528 and 5050 units are metric. Here's a breakdown of those specs:
0603: Converted to metric, it is 1608, which means that the length of the LED element is 1.6mm and the width is 0.8mm. The industry abbreviation is 1608, and the imperial name is 0603.
0805: Converted to metric system, it is 2012, which means that the length of the LED element is 2.0mm and the width is 1.2mm. The industry abbreviation is 2112, and the imperial name is 0805.
1210: Converted to metric, it is 3528, which means that the length of the LED element is 3.5mm and the width is 2.8mm. The industry abbreviation is 3528, and the imperial name is 1210.
3528: This is the metric name, which means that the length of the LED element is 3.5mm and the width is 2.8mm. Industry abbreviation 3528.
5050: This is the metric system name, which means that the length of the LED element is 5.0mm and the width is 5.0mm. Industry abbreviation 5050.
Many packages, such as some 0603, 0805 and other packaged SMD LEDs, will have a green "T" symbol at the bottom. One side of the "T" is the positive electrode, and the other side is the negative electrode. Some SMD LEDs will be marked with a silk screen similar to a triangle symbol, so the bottom edge of the triangle is close to the positive electrode, and the top corner is close to the negative electrode. The lead of the light-emitting diode is generally longer in the positive pole, and the lead in the negative pole is relatively short. Observe the shape of the two lead wires in the tube body from the side, the smaller one is the positive electrode, and the larger one is the negative electrode. Adjust the multimeter to "ohm x1", when the diode glows, the red test lead is connected to the positive end of the SMDLED, and the black test lead is connected to the negative end of the SMDLED. Because the LED turn-on threshold is about 1.5-1.8V. It is possible that the voltage supplied by the DMM cannot start it. So still look at the mark. SMD light-emitting diodes, the green dot is the negative electrode, and the opposite is the positive electrode.
