Methods for improving colour rendering - Part 2
The first part of this miniseries (see Light 1/2020, pages 16-17) demonstrated increasing the general color rendering index of a white LED by adding one or two colored LEDs. This part explores improving the Ra of light sources by using a filter that, in turn, attenuates the appropriate spectral region. The experiment again uses the method of shifting a Gaussian curve across the entire visible spectrum, but here the [...]
Installation of the S200 stomato-surgical lamp - Karlovy Vary
We like Karlovy Vary very much, so we enjoyed this assembly as well. The Luvis S200 Stomatosurgical Lamp is a luminaire for demanding procedures with an excellent price/performance ratio. In this case we mounted the lamp on the ceiling, even with an extension rod, but we also have it available in a wall-mounted or mobile version.
Ergonomics of lighting in the dental office
With Everydent, we trained dentists in lighting and overall office ergonomics as part of the Young Dentist programme. Thank you for inviting us and we hope the participants enjoyed the information-packed program.
Methods for improving colour rendering - Part 1
This article draws inspiration from less common practices that some light source and luminaire manufacturers use to improve the general colour rendering index (Ra according to [1]). Although these methods have pitfalls and some can be considered tricks, it is worth exploring them in more detail using algorithms for calculating colour rendering indices. The idea for this experiment was [...]
