LEDs are also not continuously dimmable

Visit the OSRAM booth at ISAL 2013 and be inspired from the new products and innovations - directly on the booth or inside our show car. range from single components to fully integrated solutions. There is a lot to discover: Exciting studies and concepts with insights into the future of automotive lighting and the development of innovative technologies such as LED, OLED or laser, lectures and presentations as well as new LED products from OSRAM Opto Semiconductors.

Fall is in the air and with it the annual display of brilliant foliage. Much like the vivid colors of a leaf are hidden by excess green contained in chlorophyll, the true colors in paintings displayed in many museums are masked by lighting that either lacks colors in their spectrum or contains too much of certain colors.

LED use is growing in many areas but their color composition makes them a questionable choice for displaying works of art that were originally composed under natural daylight conditions. LEDs contain a disproportionate amount of blue light and lack deep red light making the objects they illuminate appear sterile and pale. Much time and effort are put into preserving works of art. Illuminating original paintings with LED lighting that not only masks the painting's true beauty but also is potentially damaging to the pigments is not a preferred practice. LEDs are also not continuously dimmable, meaning it is not possible to change their color.
