PoE technology for LED lighting delivers benefits beyond efficiency
WEBSep 3, 2015 · Assuming a dimmable LED fixture, the AC system efficiency (82.9%) is only slightly better than the 10W PoE LED fixture with the maximum 100m cable length (82.3% efficiency). If we consider the 25m Cat5 cable, the AC efficiency is actually decreased by 1% (82.9% vs. 83.9% for the PoE LED lamp).
Running LEDs from an AC supply
WEBMay 2, 2006 · To run an LED-based fixture from a mains supply (e.g. 120 V AC) requires electronics between the supply and the devices themselves to provide a DC voltage (e.g. 12 V DC) capable of driving several LEDs. A new approach is to develop AC-LEDs, which can operate directly from an AC power supply. This provides several advantages, as …
What is an LED? - LEDs Magazine
WEBSep 1, 2004 · In the simplest terms, a light-emitting diode (LED) is a semiconductor device that emits light when an electric current is passed through it. Light is produced when the particles that carry the current (known as electrons and holes) combine together within the semiconductor material. Since light is generated within the solid semiconductor ...
Choosing between LED and HPS street lights - LEDs Magazine
WEBDec 9, 2010 · The results of the life cycle cost analyses are summarized in the chart below. Estimated life. Average life cycle cost per mile of recommended LED streetlights. Average life cycle cost per mile (excluding poles) of the "higher power" LED street lights. 25,000 hours (6 years) 2.6X incumbent 150W HPS. 2.3X …
Osram completes LEDvance sale to Chinese consortium for €500 …
WEBMar 3, 2017 · Meanwhile, new co-owner MLS is expected to provide LEDvance with better chip pricing. With regulatory concerns now cleared in three countries, Osram has completed the sale of its LEDvance lamps group to an investor-led Chinese consortium for around €500 million ($529 million), about 25% more than the amount widely reported last July.
Lighting systems leverage DC distribution for maximum efficiency ...
WEBApr 1, 2014 · Let’s discuss how DC-grid technology can deliver significant energy savings, especially when combined with inherently efficient LED sources. Lighting systems leverage DC distribution for maximum efficiency. FIG. 1. LED lighting powered directly from a DC grid run through a drop-ceiling frame helps boost efficiency at the room or building level.
Technology roadmap shows UV-C LEDs are on the rise - LEDs …
WEBJul 24, 2020 · Market analysts, even prior to COVID-19, predicted a UV LED market exceeding $1 billion in a few years, to be compared with the lighting LED market, which was $5.8 billion in 2019, after growing for many years now. In addition, large LED players, including Nichia and San’an, are notably investing in the UV-C LED market, no doubt in ...
About LEDs Magazine | LEDs Magazine
WEBApr 23, 2024 · About Us. For years, LEDs Magazine and its events have been known as “component centric.”. While that identity has served us well, it doesn’t fully illustrate the breadth of content, thought leadership, and subject-matter expertise that LEDs delivers from the lighting manufacturing, design, and supply chain. LEDs Magazine continuously ...
How to interpret LED lamp data - LEDs Magazine
WEBApr 14, 2011 · The company sells LED lamps under the Verbatim brand. Fig. 1. MCC natural vision LED Luminous flux, measured in lumens, is the level of light emitted by the lamp. Dividing this by the power consumed gives you an indication of the lamp’s efficiency and the result is expressed as lumens per Watt.
