Narrow Band IoT (NB-IoT) is a Low Power Wide Area Network (LPWAN) radio technology standard that has been developed to enable a wide range of devices and services to be connected using cellular telecommunications bands. NB-IoT is a narrowband radio technology designed for the Internet of Things (IoT), and is one of a range of Mobile IoT (MIoT) technologies standardized by
1. Content This design guide will introduce uPowerTek’s constant current LED driver in different aspects, including its features, strength and how the NFC programmable LED driver works. 2. Introduction of uPowerTek uPowerTek is a high-tech company which has been dedicated in high quality and intelligent LED drivers for several years. The headquarter including sales, R&D
Outdoor lighting especially street light, tunnel light are difficult and expensive to repair, so the LED drivers for those applications need not only great reliability and high protection level, but also long life so that the lights can be operating for at least 5 years. This article is showing how to make sure the LED
This article illustrates the necessity of using high accuracy LED drivers for general lighting and how to realize it. The phenomenon of bad consistency Take office lighting for example, people are looking for a lighting system like this: Rather than this especially when the lights are dimmed down: LED driver output current impacts the light
Type TL LED Driver Program Class P LED Driver Program Luminaire Report LED Driver – R/C FKSZ2, made by manufacturer, model cat. no., Type TL. Specifications included in report: · Input ratings · Input type · Supply connection method · Output ratings · Output type · Tref values · Environmental conditions
Have you been seeking greater flexibility and safety in lighting products without the time and expense of recertification? The Class P LED Driver Program can help. LED technology not only offers greater efficiency and longer lifetimes, but it also offers greater design freedom. With the Class P LED Driver Program, you can now take full advantage of all of
Background: Current requirements of UL 8750 for LED drivers provides for variability in test conditions such as load types, ambient temperatures and permissible temperatures during abnormal testing. This approach offers flexibility with the safety evaluation, but requires detailed review of the test program and partial testing of the LED driver when it is integrated into
Nowadays, most of the LED drivers in the market supports programming output current and other parameters, this article describes how to program the LED driver by NFC technology. 1. NFC (Near Field Communication) Introduction NFC (Near Field Communication) is now frequently involved in everybody’s digital life, such as transportation, security, payment, cellphone data exchange and
If you follow developments in the tech industry on a semi-regular basis, you’re likely familiar with the terms near-field communication (NFC) and radio frequency identification (RFID). Recently, you may have seen RFID in the news, or you may have been told that your cell phone is an NFC device. In any case, this article will
DALI is a very popular dimming and control technology in the world, but there are two many concepts and new technologies in recent years, so we write this article to help you understand the DALI dimming technology and help you to be a DALI expert, we believe it will help your work, keep reading. 1
LED lighting systems continue to soar as we can see everywhere. But do you know that there is a driving force as the key component behind the LED fixtures? They are the LED drivers. The LED power supply regulates the LED fixture’s power (voltage or current), thus precisely controlling the light output. In addition, high quality LED
LED lighting penetrates everybody’s life, becoming more intelligent and more sophisticated. When designing high quality and excellent luminaire, the design engineer must carefully understand the LED Driver since it is the heart of a light fixture. This article describes the most frequently used LED driver concepts and provides the methods to select a suitable and
