1. 1. Fabrication and characterisation of RGB LEDs based on nanowire technology

   Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Författare :Patrik Olausson; [2019]
   Nyckelord :RGB LEDs; InGaN; GaN; nitrides; platelets; nanotechnology; Technology and Engineering;

   Sammanfattning : The white light LEDs of today are usually based on a blue LED and a phosphor, converting the blue light to longer wavelengths. While these phosphor-converted LEDs are extremely efficient compared to incandescent light or fluorescent light, there is still plenty of room for improvement. LÄS MER

3. 2. LED CommunicationFor Short Range Wireless

   Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Författare :Ketong Li; [2015]
   Nyckelord :Visible light; LED communication and VLC modeling;

   Sammanfattning : With the huge development of semiconductor lighting technologies, the light emitting diodes (LEDs) are promising technology that eventually replacing traditional incandescent and fluorescent lamps for their high power efficiency, environmental friendliness and long predicted product lifetime. Besides lighting, the advent of high-brightness, fast-switching LED lamps has facilitated LED Communication as a new form of Optical Wireless Communication (OWC) in the visible light spectrum.

4. 3. Glödljus vs. LED-ljus : En rumslig analys av ljuskvalitén i hemmiljö

   Kandidat-uppsats, Högskolan i Jönköping/JTH, Belysningslära

   Författare :Csikós Attila; [2014]
   Nyckelord :affect of light; environment; home environment; halogen bulb; incandescent light; LED-light; light; lighting quality; room experience; wellbeing; glödlampa; halogenlampa; hemmiljö; LED-lampa; ljus; ljuskvalité; miljö; påverkan av ljus; rumsupplevelse; välmående;

   Sammanfattning : Det finns fortfarande för många hushåll i Sverige som använder mest glödljus för belysning, i form av glödlampor eller halogenlampor. Detta orsakar en väsentlig del av det onödiga överskott av koldioxidutsläpp som är en av orsakerna till den globala uppvärmningen. LÄS MER

5. 4. Household Waste Collection Policies for Mercury-Containing Light Sources in Sweden: Status and Trends

   Master-uppsats, Lunds universitet/Internationella miljöinstitutet

   Författare :Stefan Sipka; [2012]
   Nyckelord :Sweden; mercury; light source; policy; waste collection; household; Earth and Environmental Sciences;

   Sammanfattning : The thesis explores the possibilities of the Swedish government to assure effective waste collection policies for mercury-containing gas-discharge lamps (GDL) in the context of phase-out of incandescent light bulbs. The study includes review of the waste collection, the waste collection evaluation, policy review and policy analysis. LÄS MER

7. 5. Energy and cost analysis of household electricity efficiency improvements in a rental apartment building

   Master-uppsats, Institutionen för teknik och hållbar utveckling

   Författare :Manaswita Panigrahi; [2012]
   Nyckelord :household electricity; energy efficiency; cost analysis; CO2 emissions;

   Sammanfattning : In this thesis potential for (final and primary) energy and CO2 emission reductions and cost effectiveness of replacing existing household electric appliances and light bulbs with most popular or most energy efficient appliances in a multifamily apartment building in Växjö city is studied. The results showed that there is significant potential to reduce electricity demand and thereby to reduce primary energy use and CO2 emissions. LÄS MER
