WHITE PAPER - Measuring Color Uniformity

WHITE PAPER - Measuring Color Uniformity

The color uniformity of light generated by LED luminaires plays a major role in many lighting applications. This makes it an important parameter to measure in both the R&D stage and during the quality assurance process. MKS Instruments has stayed abreast of this challenge by developing a new feature for its FluxGage photometrical system: the color uniformity measurement function. It allows quick evaluation of optical assemblies for color mixing and beam shaping. This whitepaper presents this novel feature of the system.

Cezos Introduced New Magnet Switch for Inside Cabinet LED Lighting

Cezos Introduced New Magnet Switch for Inside Cabinet LED Lighting

Cezos is delighted to present their new magnet switch, L475T, which is a specialized controller designed to drive a LED light inside cabinets etc. Due to a 3-axes MEMS magnetometer sensor it can extremely precise detect minimal changes in the magnetic field. Therefore, the distance to the magnet can be wider than with traditional sensors (e.g. mechanical). The calibration algorithm detects the best axis when the door is opened for the first time, so the mounting direction is not relevant. The soft adjustment of the light protects the eyes. If the door will not be closed, the light turns off automatically after 15 minutes.
