Connectivity and sensors company TE Connectivity has introduced a new compact connectivity solution for street lighting with LED light sources. Its Lumawise Endurance S module consists of a standardised interface (Zhaga Book 18) between the receptacle and module base or sealing cap. It uses an integrated single gasket that can accommodate and seal both luminaire […]
When I initially thought about writing this article, it was to discuss some of the different categories of luminaire. After more careful contemplation, I thought it best to reflect on the changes I have observed over my 46 years in the lighting industry. The question I began to ask myself is, “what has changed”? […]
LEDs use 75% less energy and offer a viable energy-efficiency opportunity but can have significant impacts on power quality as they are non-linear loads. LED lighting technology is significantly more complex than “traditional” incandescent light bulbs. It comprises many different components, each of which may have an impact on power quality. The semiconductor diode used to […]
Robust circuit protection is needed to minimise costs and maximise return on investment of LED street lighting solutions. LED street lights produce whiter, cooler light when compared with the yellowish light cast by high-pressure sodium lamps. They reduce the potential for collisions by enhancing drivers’ depth of field and peripheral vision. However, installing LED fixtures […]
The application of formulated chemical products for thermal management within the rapidly expanding LED industry. Chemical products are used widely in the electronics industry for a vast array of applications. Whether it is during printed circuit board manufacture or for the protection of components or complete devices, these products have become an essential factor in […]
This article introduces a novel indoor positioning system that uses visible light then compares it with other indoor positioning systems, and discusses its potential applications. Indoor positioning systems underpin applications in diverse areas such as automatic monitoring systems, indoor navigation, and retailing. The demand for highly accurate low-cost indoor positioning systems is rapidly increasing. […]
Radio amateurs are serious about tackling the problem of RF pollution and the resultant increase in the radio frequency noise floor. Since the beginning of the year interest groups have sprung up in various countries around the word and national amateur radio organisations are taking a serious stand and in several countries are accusing […]
At one stage producers of television sets focussed their research and manufacturing capabilities on organic light-emitting diodes (OLEDs) to produce the perfect TV picture and images on hand-held devices, but with the announcement of quantum dot technology that focus has fast shifted. At the Samsung Africa Forum 2017 held during February in Cape Town […]
