Epistars advances warm white light efficiency to 170 lumens per watt with advanced high voltage LED technology

Posted on

Epistar Lab has successfully developed a number of technologies, including a new generation of transparent substrate conversion processes, fine structures that increase photon extraction rates, and improved current distribution uniformity, enabling red LEDs at wavelengths. The efficiency is 174 lm/W at 610 nm. At the same time, in the case of high-voltage blue LEDs, when combined with a combination of conventional wavelength conversion materials, it can be verified that the warm white light with an excellent temperature of about 2800K has an efficiency of 170 lm/W and a color rendering of 88. The above results were achieved today, not only exceeding the target, but also continuing to lead the industry.
Jingyuan Optoelectronics will continue to develop more advanced technologies to enhance the performance of its products, and work with midstream and downstream customers to promote LED light sources to the lighting market.

Fast Ethernet Switch is 10/100Mbps adaptive fast Ethernet Optical Media Converter, with 10M/100Mbps self-adaptive switch, converting the independent 10Base-T or 100Base-TX twisted pair electrical signal with 100Base-FX optical signal. It extends the network transmission range from 100m, the limit of copper line, to 120Km (single mode full duplex). It supports two different types of network connection media, 10/100Base-TX and 100Base-FX. By switching technique and storage & forwarding technique, it realizes the data transmission between two network connection media. It supports optical transmission under dual-fiber multi-mode, dual-fiber single mode, and single fiber single mode.
