Human Centric Lighting
Light influences the well-being of people, characterizes their day and night time rhythm and effects activity and the ability to concentrate. The earth’s natural lighting cycle controls human beings’ inner clock, the circadian rhythm. During the day the color temperature changes from warm, reddish 3000K in the morning, to a mid-day average of light 5500K to 6500K suppressing melatonine production and increasing the attention level back to warmer CCTs in the afternoon and back to relaxing 3000K during the evening hours causing melatonine production. While light we are used to is quite static the idea of Human Centric Lighting is to mimic this natural light cycle. It promotes well-being, can improve concentration, supports healing processes and prevents from sleeping disorders.

How does light affect the plant growth?
The amount of light affects the photosynthesis process in the plant. This process is a photochemical reaction within the chloroplast of the plant cells in which carbon dioxide is converted into carbohydrate under the influence of the light energy.
Light quality regarding spectral composition of the light
The spectral composition of the different wavelength regions (blue, green, yellow, red, far red or invisible e.g. UV or IR) is important for the growth, shape, development and flowering (photomorphogenesis) of the plant. For the photosynthesis, the blue and red regions are most important.
The length of day and night required for initiation of flowering is called "photoperiod" which can be influenced by light exposure.
Laser front light
The laser beam triggers excitation of a phosphor inside the headlamp, causing it to illuminate. This “transformation” of the laser light is referred to as “conversion”. The phosphors are high-performance ceramic substances that can contain phosphorus compounds.
Why laser light for motor vehicles?
LEDs emit light in an angular range, meaning that the light beam broadens as the distance to the source increases. In the case of a laser diode, the light is emitted from a very small surface area with comparatively minimal divergence. Thanks to this extremely high density of the laser light, a very small spot can be generated at the converter, making it possible to design very compact headlamps with a narrower beam for greater distances Laser-based headlamps need a diameter of only 30 millimetres to generate high beam light with a luminous intensity of 100,000 candelas (cd).
