Lumino scores particularly well in the field of safety lighting. For both exterior and interior applications.
The very special: We can produce almost any desired shape for you.
Lumino® products are made of polymer concrete, an environmentally friendly material that is much harder, more durable and more resistant than normal cement concrete. By refining the surface structure, PolyCare has succeeded in making these products glow independently in the dark.
The luminous effect is created by luminescent particles that emit the UV light absorbed during the day as light radiation in the dark. This is a purely physical process in which quantum leaps in the material are triggered by light photons and which is not subject to any signs of wear. The lamps used are neither toxic nor radioactive and are EN 71-3 approved (toy standard).
At night, the gentle lighting effect makes Lumino® products ideal landmarks that require neither batteries nor electricity. These products achieve optimum luminosity if they can absorb sufficient light. Artificial light is also sufficient for the "excitation period". The higher the illuminance in the phase of the excitation duration, the faster the pigments charge up.
The blue-violet area of the light is mainly used to excite the luminous pigments. Daylight, LED, fluorescent or halogen lamps are therefore ideal. The yellow light of low pressure sodium vapour lamps, on the other hand, is unsuitable. The luminous pigments also emit light again in terms of brightness.
However, this is hardly perceptible to the eye, as this light effect is superimposed by the other light sources.
Scientifically, the measure of human perception of the brightness of a surface can be determined by measuring luminance. Luminance is measured in mcd/m². As a rule, a light measurement according to DIN 67510 "Measurement of photoluminescent products at the place of application" ends when luminance has reached 0.3 mcd/m² (approx. 100 times the value of the visual limit).
In complete darkness the Lumino® paving stones reach this value only after 4 days, 10 hours and 7 minutes.
It should be noted that the human eye takes some time to get used to complete darkness. If our products have received enough light (including artificial light) before dark and no other stray light is available, the lighting effects are optimally visible. During the course of the night, luminance naturally decreases, but this is compensated by the increased night vision of the human eye. Through this adaptation of the eye, even apparently low luminance levels are still very well visible. The Lumino® products have a very high light-dark contrast and therefore stand out very well in a lightless environment.
Due to these properties, Lumino® products are ideally suited for the marking of escape and rescue routes. Even in the event of a fire and simultaneous power failure, they ensure that escape routes without lighting and simultaneous smoke extraction are reliably detected and can be evacuated as quickly as possible. The latest workplace regulations stipulate in ASR 3.4/3:
"Photoluminescent safety guidance systems shall be designed and installed such that the luminance of photoluminescent materials, measured at the place of use, is not less than 80 mcd/m² (millicandela/m²) after 10 minutes and not less than 12 mcd/m² after 60 minutes". Lumino® exceeds these values by a factor of 4 or more.
The use of Lumino® as a safety guidance system offers a number of economic and safety-related advantages:
