Seoul Semi Launches LED Environmental Campaign

The new incentive highlights the company's eco-friendly Acrich III-nitride LED bulbs which do not require an AC/DC converter
Seoul Semiconductor is launching a global campaign called "Acrich for Trees" to actively encourage the use of eco-friendly AC LED bulbs with Acrich LEDs.

Seoul says its Acrich bulb saves two more trees than conventional DC LED solutions.

Interested parties can join the campaign from April 11th to April 30th, 2013 via the firm's official website,

The Campaign of planting 2 trees held by Seoul Semiconductor

Among participants who access the website and subscribe to the Seoul Semiconductor Newsletter, 1,000 subscribers will be chosen to receive a LED bulb or a LED desk lamp.

By using an Acrich LED light bulb six hours per day, annual carbon dioxide emissions are decreased by roughly 48kg compared to using a normal 60W incandescent light bulb.

What's more, the absence of an AC/DC converter (typically used in DC LED bulbs) reduces energy loss even further. Results based upon Seoul Semiconductor’s internal study and data from the investigation comparing conventional and DC LED bulb solutions with an 8W Acrich bulb are shown in the table below.

Marten Willemsen, global marketing VP, says “Seoul Semiconductor is the world’s first company to succeed in developing and producing eco-friendly Acrich LEDs. This solution is more environmental friendly because it does not require an AC/DC converter. By eliminating the drawback of an analogue converter’s short durability, the life expectancy of LED light bulbs has dramatically increased."

He also highlights that “This global campaign encourages people to use eco-friendly LED bulbs with Acrich LEDs to save more trees than conventional DC LED bulbs."


AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
