Outdoor anti-vandal floodlights and luminaires
In collaboration with the State Unitary Enterprise LENSVET, TRIF's specialists have conducted a large-scale survey of outdoor LED luminaires installed on the city streets and squares in St. Petersburg. The survey covered both in-pavement luminaires and architectural facade lights that had been in free public access for a long period of time (up to 10 years).
The experts determined the two main reasons for the majority of outdoor luminaires to start failing: the adverse impacts of the environment, and the human factor.
Adverse External Factors:
- Extreme temperatures from -40° C to +40° C;
- The impact of chemical agents that are used in winter. Salts affect not only in-ground luminaires but also lighting fixtures installed several meters above the ground level, in case the agents are distributed with the help of specialized equipment in windy weather;
- High humidity, several days of heavy rains that are followed by near-zero temperature fluctuations and icing-up. When the ice expands in the cavities and apertures present in the bodies of luminaires and floodlights, it leads to a loss of sealing in the body and electrical junctions;
- A large number of freezing/thawing cycles in spring, autumn, and winter (hundreds of cycles a year);
- The cavities are filled with natural debris: leaves, dust, dirt, insects.
- Any cavity is eventually filled with all kinds of garbage: banana peels, cigarette ends, half-eaten ice cream, etc. Being filled with garbage leads to overheating and failure of outdoor luminaires and floodlights;
- Intentional damage: kicks and hits with bottles or paving stones; attempts to wring out the luminaire; airgun shots;
- Attempts to steal the luminaire or at least change the direction of the light flow.
As a result, the experts determined the range of technical requirements that would allow designing anti-vandal outdoor lighting fixtures capable of long-term failure-free functioning.
Technical requirements to outdoor anti-vandal floodlights and luminaires mounted at a height of under 2.5 meters:
- No cavities or apertures in the anti-vandal luminaire body;
- Using impact-resistant Plexiglas to protect the light-emitting diodes. It must be at least 10 mm thick for diameters under 120 mm, and at least 20 mm thick for diameters over 120 mm;
- Using hardened glass is acceptable in certain cases;
- IP68 or higher protection class (to ensure continuous operation while submerged in water);
- The anti-vandal outdoor luminaire body must have 10 mm or thicker walls if aluminum is used, and 5 mm or thicker walls if stainless steel is used (to ensure resistance to being hit with stones);
- The pivot mechanisms of floodlights must be hidden to exclude the possibility of rotating them by hand;
- Outdoor anti-vandal lighting fixtures must not feature any open and accessible electrical wiring.
Technical requirements to outdoor anti-vandal in-ground floodlights and luminaires:
- The upper flange is made from stainless steel with a thickness of at least 3 mm for pedestrian traffic and at least 5 mm for vehicular traffic;
- The Plexiglas plate protecting the light-emitting diodes should be no less than 20 mm thick (outdoor anti-vandal luminaires must be capable of withstanding the load and impact of studded snow tires);
- The upper flange and the Plexiglas plate must be within the same plane (to prevent dirt accumulation);
- Anti-vandal in-ground luminaires must feature the IP 69K level of protection (to ensure their flawless functioning in water and resistance to aggressive chemical agents sprayed under pressure);
- Class of an udaroprochnochta IK10 which provides high resistance of covers (cases) of electric equipment to blows.
- Any models that lack a flange (for example, the TRIF ICE series of LED paving stones) must feature a Plexiglas plate with a thickness of at least 40 mm;
- Regardless of the pavement type, all in-ground luminaires must have anti-vandal anchoring elements.
If all the above requirements are met, the outdoor luminaires and floodlights will function flawlessly for many years and require no additional maintenance and repair spending!
