Artificial lighting

Artificial lighting

Any light source other than natural light. Artificial light sources include those with a continuous spectrum such as candles, normal electric light bulbs (tungsten lighting), special photographic light bulbs, photoflood bulbs, as well as discontinuous light sources such as fluores-

And it is well that nature has so graciously and abundantly lighted the Martian night, for the green men of Mars, being a nomadic race without high intellectual development, have but crude means for artificial lighting; depending principally upon torches, a kind of candle, and a peculiar oil lamp which generates a gas and burns without a wick.
They added flying insects have a tendency to be attracted towards artificial lighting, which can force them to move out of natural ecosystems.
The new findings indicate use of artificial lighting instead is growing, increasing energy demand.
Summary: New Delhi [India], August 30 (ANI): Moving along the pathway to realise their environmental ambitions, the Norwegian Embassy here registered record-low power consumption below 140 kWh/m2 per year by focusing on planning the layout of the building in a way to reduce artificial lighting and cooling.
But the latest research reveals that these creatures might be at risk from artificial lighting. Scientists working in Switzerland report a big drop in pollinator visits as well as reduced fruit production in patches of cabbage thistle (Cirsium oleraceum) under artificial lighting at night, in a study published on August 2 in Nature.
The images show the parts of the Earth that humans currently inhabit, signified by the intensity of artificial lighting emanating from these areas.
In a study published in 2012 in the journal Molecular Psychiatry, researchers noted the depressive effect of artificial lighting on rodents.
The zone has artificial lighting controls with a 500 lux illuminance set point facing the ceiling.
If natural light is not available, the study suggests optimizing the spectrum, intensity and variability of artificial lighting to support positive behaviors.

In the course of cultivation, it has been established that use of the circle of Bogdanov allows receiving the maximum concentration of cages of microalgae both in flasks and in the photobioreactor with natural and artificial lighting. Therefore, we have chosen this environment for further experiments.
