Light emitting diodes (LEDs) have become the main light sources for general lighting, due to
their high lumen efficiency and long life time. Moreover, their high bandwidth and the …

Light emitting diodes (LEDs) are considered to become the dominant source of illumination
in the future, offering long life times, energy efficiency and flexible tunability. The flexibility of …

An efficient LED lamp that illuminates the street with high quality is presented. The luminaire
shows high optical efficiency, high optical utilization factor, low glare, and illuminates the …

Precise optical modeling of blue light-emitting diodes (LEDs) is constructed by reasonable
optical parameters and Monte Carlo ray-tracing with the capability of precisely predicting …

In order to resolve the problem of energy hunger nowadays, saving lighting energy in
buildings contributes an important part. In this paper, a sensorless illumination control …

Street lighting, which is one of the main players in energy waste and light pollution at night,
still faces the challenge of efficient lighting of roadways with curved and twisted shapes. To …

In this paper, we start from the study on the packaging efficiency of the phosphor-converted
white LED via a new way to measure and calculate the blue light from the blue die to the …

This paper is an attempt to survey the benefits of a well-designed photoreactor containing
just 6 ultraviolet (UV) high power light emitting diodes (HPLEDs); the power and wavelength …

This paper examines how the initial condition of mangoes impact the effectiveness of UVC
treatment. Specifically, we treated two distinct groups of mangoes with different initial …
