  3. 2. Organic electronic switch devices

    Författare :Fredrik Jakobsson; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Since the discovery of conducting polymers three decades ago the field of organic electronics has evolved rapidly. Organic light emitting diodes have already reached the consumer market, while organic solar cells and transistors are rapidly maturing. One of the great benefits with this class of materials is that they can be processed from solution. LÄS MER

  4. 3. Towards Novel AlGaN-Based Light Emitters

    Författare :Martin Stattin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; AlGaN; light emitting diode; deep ultraviolet; III-Nitrides; near infrared; quantum cascade laser;

    Sammanfattning : The unique properties of the AlGaN semiconductors make them a suitable choice for optoelectronic devices at both short and long wavelengths, based on interband and intersubband transitions, respectively. What sets AlGaN apart from other wide-bandgap semiconductors is the possibility to obtain both p- and n-type conductivity as well as the direct bandgap. LÄS MER

  5. 4. Do lighting control and user interface design matter to occupant behaviour? The case of optimal lighting use in non-residential buildings

    Författare :Pimkamol Mattsson; Institutionen för arkitektur och byggd miljö; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; characteristic; design; energy reduction; energy-saving behaviour; lighting control; light switch; lighting use; non-residential building; perception; user interface;

    Sammanfattning : The lowering of energy use from artificial lighting in buildings is vital to reaching the goal of reducing CO2 emissions. Hence, changes in individuals’ behaviours regarding lighting use have received increased attention. Feedback on energy use has often been used to change individuals’ behaviour. LÄS MER

  7. 5. Lighting Control Systems for Energy Saving and User Acceptance: State-of-the-art and future directions

    Författare :Niko Gentile; Institutionen för arkitektur och byggd miljö; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Indoor lighting; lighting control system; lighting control; energy saving; energy efficiency; user acceptance; human factor; occupancy strategies; absence sensor; presence sensor; lighting switch; manual switch; daylight harvesting system; daylight-linked system; photoelectric dimming; photosensor.;

    Sammanfattning : Lighting accounts for one-fifth of global electricity use. In Sweden, energy demand for lighting corresponds to 20% of the total electricity use in office buildings. Lighting retrofit measures are considered to be among the most cost-efficient way to reduce energy use in buildings. LÄS MER
