On the benefits of cooperation via power control in OFDM-based visible light communication systems
(IEEE, 2014)
In this paper, the performance of a visible light communication (VLC) network exploiting power control is considered. The achievable rate region of two VLC communication pairs is characterized. The system employs optical ...
Development of various corner-lit backlighting concepts in an advanced smart LED TV
(2015-01)
CCFL (Cold Cathode Florescent Lamp) based LCD (Liquid Crystal Display) TVs are replaced by Smart LED TVs with the help of recent improvements of the LED (Light Emitting Diode), electronics and information technologies. ...
The impact of location errors on achievable rates in OFDM-based multi-user visible light communication systems
(IEEE, 2014)
Visible light communication (VLC) is a communication technology in which data is transferred by modulating the visible light intensity. VLC signals degrade significantly due to the absence of the line of sight (LOS) between ...
Direct liquid cooling of high flux LED systems: hot spot abatement
(ASME, 2013)
With the recent advances in wide band gap device technology, solid-state lighting (SSL) has become favorable for many lighting applications due to energy savings, long life, green nature for environment, and exceptional ...
Limitations of passive thermal management for a-line solid state lighting technologies
(2015-01)
Energy has been one of the most important problems for the last few decades. Efficient use of energy is as important as efficiency in energy production and transportation. Solid state lighting (SSL) technology may reduce ...
An investigation into thermal and optical performance of multi-purpose LED automotive exterior lighting systems
(2015-12)

Generalized LED index modulation optical OFDM for MIMO visible light communications systems
(IEEE, 2016)
In this paper, we propose a generalized light emitting diode (LED) index modulation scheme for multiple input multiple output-orthogonal frequency division multiplexing (MIMO-OFDM) visible light communications (VLC) systems. ...
A European view on the next generation optical wireless communication standard
(IEEE, 2015)
Optical wireless technology uses light for mobile communications. The idea is to simultaneously combine the illumination provided by modern high-power light-emitting diodes (LEDs) with high-speed wireless communications. ...
An experimental and computational study on efficiency of white LED packages with a thermocaloric approach
(IEEE, 2017)
Thermal management of light-emitting diode (LED) chips is crucial for light extraction and lifetime. It is well known that the light output of an LED decreases with the elevated temperatures. For higher light extraction, ...
Channel modelling and performance limits of vehicular visible light communication systems
(IEEE, 2020-07)
Visible light communication (VLC) has been proposed as an alternative or complementary technology to radio frequency vehicular communications. Front and back vehicle lights can serve as wireless transmitters making VLC a ...
