LED lighting has advanced considerably in the past few years, but still has problems with the quality of light produced and lighting device control. Quantum dot (QD) technology offers a solution to many of the problems with current LED lighting products. This technology was initially applied to luminous displays and television (video) screens but is […]
The process used to determine thermal resistance values from the LED junction-to-case and LED junction to Ts reference point. Part 1 of this article discusses measuring junction-to-case thermal resistance; determining the K-factor and testing Rth J-C (see Vector, March 2019, page 25). Thermal performance is the most critical aspect of a well-designed LED lighting system. […]
The process used to determine thermal resistance values from the LED junction to case and LED junction to Ts reference point. Thermal performance is the most critical aspect of a well-designed LED lighting system. Lighting installations with proper thermal designs have higher efficacy, meaning more light can be extracted using less energy, providing better long-term […]
Correlated colour temperature and colour rendering index are becoming outdated as lighting metrics such as LED technology develops and customers become discerning. Selecting the correct LED lighting products for both exterior and interior spaces has become essential in today’s fast-growing built environment and, with the advancement of LED, it is now easier to select suitable […]
Notes on providing lightning protection for LED mast lights with double or reinforced insulation; large masts fitted with supply distributors PVC masts and others. LED mast lights for street, walkway and open space lighting are mounted at light point heights of several metres to ensure large fields of illumination. This, however, is only possible if […]
An innovative digital lighting concept brings new splendor to the artistic treasure of the world’s largest basilica. The famous St Peter’s Basilica at the Vatican now shines in brilliant light following nearly 18 months of planning and the installation of a new LED lighting system. The entire lighting concept for the project was tailor-made by […]
Special optical adhesives enable the encapsulation of LEDs, termination of optical fibres and the assembly of complex lens systems. Optical grade epoxies, silicones and UV curable compounds offer engineers great versatility for bonding, sealing, coating and encapsulation applications. These systems adhere well to diverse substrates and offer excellent temperature resistance, stress relief and protection from […]
New lighting technologies are about to change the way we do lighting design, how we install lighting and how we will use it. Day is, of course, divided into daytime and night time or, put another way, light and dark. Daylight gives us energy and we can see to perform our tasks. Our bodies are […]
This article discusses ways in which connected lighting systems can support major trends in the transformation of offices. Several major trends are driving the transformation of the traditional office space: Globalisation: with organisations and employees frequently distributed across multiple geographical locations. Changing demographics: As generations Y and Z, as well as “generation next” employees enter […]
The LED chip is the core component of LED lighting. If the chip temperature is too high, the LED life and luminous quality could be severely affected. A heat sink is a common component in many electronic devices. It transfers the heat created by a device, acting to reduce the device’s temperature to prevent overheating. […]
