The first post was about general lighting. In this post, Nichia will discuss specialty lighting which requires a higher CRI. Applications requiring high color rendering include lighting for printing, painting, dyeing, photography, color inspection, cosmetic mirror lighting, galleries, museums, clothing, decorations, hospitals, and schools. Depending on the application, various types of high CRI lamps are used. Incandescent bulbs and halogen lamps have an Ra of 100, but their color temperature is as low as 2700K, limiting their use in applications. For applications requir...

As of today, 24 February 2023, most types of fluorescent lamps will be banned from manufacturing and sales in Europe. Despite containing mercury, these lamps have been allowed to be manufactured and sold as exemptions from the RoHS Directive. However, these exemptions end today and will no longer be extended. Lamps not covered this time will be subject to regulation in a phased manner, and general fluorescent lamps, except for some special applications, will disappear from the market in the near future. Under the Minamata Convention, which along with the RoHS Directive, i...

In the lighting industry, the characteristics and advantages of light sources are typically discussed in terms of luminous flux and/or efficacy; however, CRI, chromaticity, and spectral distributions are also important factors of light. Among these, CRI is a very important characteristic that determines how close an illuminated object looks to what it would like under natural light. In this blog, Nichia has chosen to focus on CRI and its history as the main theme and this first blog post will discuss the importance of general lighting, which is indispensable in our daily lives. ...
