Company Profile
JTX (Shandong Prosperous Star Optoelectronics Co., Ltd.) is engaged in research, development and manufacturing of graphene-enhanced LEDs and LED lighting products. Established in 2014, JTX is a newcomer in the already crowded, hyper-competitive market but has demonstrated incredible confidence and ambition through its heavy investment into LED filament technologies and manufacturing infrastructure. In July 2016, JTX was merged with Graphene Lighting PLC, a UK-based startup that specializes in graphene lighting technology. JTX and Graphene Lighting PLC respectively own a 70 percent and 30 percent equity stake in the new venture. The merging makes an inventive technology paired with a world-class manufacturing infrastructure. Graphene Lighting can speed up the distribution of graphene enhanced lighting technology much more quickly than expected due as the capacity of JTX's production lines, whereas JTX is well-armed with patented technology from Graphene Lighting to build its core product lines. JTX's independent intellectual property portfolio serves as a solid foundation to market its products in the global market and license to its worldwide business partners.

The graphene lighting technology, developed by Graphene Lighting in collaboration with Manchester University and the National Graphene Institute (NGI), basically deals with graphene coating that aids in heat dissipation and thus contributes to longer lifetime and better efficiency. The technology has been successfully implemented on LED filament bulbs. In the absence of a heat sink, conventional LED filament bulbs are typically filled with a high thermal conductivity gas inside the bulb to help with the heat dissipation. However, Using inert gas does not sufficiently ensure a low junction temperature (Tj) which directly correlates to the life expectancy of the LED filaments. Graphene is a single layer of carbon atoms arranged in a hexagonal pattern to form a one-atom thick layer of graphite. The honeycomb structure contributes graphene's incredible strength and excellent thermal conductivity. The superb mechanical strength of graphene also allows for greater design flexibility which is the cornerstone of Graphene Lighting's patented curved filament design.

JTX's manufacturing facility is located in Tai'an, Shandong, China. Encompassing a floor area of 160,000 square meters, JTX builds itself a modern, robust infrastructure to support the commercialization of the latest technology. The facility is equipped with latest manufacturing systems including 50 LED packaging lines, 10 EMC frame production lines, 10 LED filament bulbs production lines, and 5 SMD LED lines. JTX's LED filament bulbs feature the highest level of vertical integration with all major components, e.g. LED filaments, ICs, power supplies, produced in-house. JTX has built a broad patent portfolio surrounding the LED packaging technologies including CSP, filament, and EMC.

JTX's products are CE, UL, SAA, and PSE certified. The company's marketing center is located in Shenzhen, China.
