The Insurance and Legal Value of UL/ETL Certification In the professional lighting sector, certifications like UL (Underwriters Laboratories) and ETL (Electrical Testing Labs) serve as more than mere ...

Evaporation-assisted chip cooling lowers LED temperatures while preserving heat flow for small but useful waste-heat energy ...

To get the maximum brightness and working life out of a high-power LED, it needs to be driven at the optimum specified current. Allowing the current to exceed the permitted value is to be avoided at ...

The XLamp XR-C high-power LEDs series has been expanded, adding royal blue (450 to 465-nm), blue (465 to 475-nm), and green (520 to 535-nm) units with a 100 viewing angle, and amber (585 to 595-nm), ...

LEDs with low polarization in a direction similar to standard LEDs show greater efficiency at higher power by resisting 'efficiency droop', a new study shows. The findings open the door to a new ...

ANSAN, South Korea--(BUSINESS WIRE)--Seoul Semiconductor Co., Ltd. (KOSDAQ: 046890), a leading global innovator of LED products and technology, announced another victory in a patent infringement ...

Most engineers are quite familiar with typical low-power-indicator LEDs, whether they be surface-mount or the classical through-hole packages. All that's needed to use them is a voltage source and a ...

Light-emitting diodes (LEDs) are everywhere in modern life, from smartphones to home lighting. But today's LEDs have a major limitation: when you try to make them brighter by increasing their power, ...
