Technical Lighting for Farms and Breeding Facilities: Extreme Resistance and Animal Welfare
Lighting in agricultural and livestock facilities goes beyond mere visibility; it is a fundamental productive and biological factor. At Todo-Lux, our lighting for farms and breeding facilities is engineered around two critical pillars: maximum resistance against highly corrosive atmospheres and the optimisation of the photoperiod to ensure animal welfare and maximise production conversion rates.
Resistance and Tightness Engineering (IP69K)
The environment of a poultry, pig or cattle bay presents one of the most aggressive atmospheres for electronics due to the concentration of corrosive gases (ammonia and hydrogen sulphide), high humidity and airborne dust. Our luminaires integrate specific materials and seals to operate without degradation in these conditions:
- Special Polymers (PMMA vs PC): Unlike conventional high bays or batten luminaires made of polycarbonate (PC) which crystallise and crack on exposure to ammonia, we use diffusers and enclosures of PMMA (Polymethylmethacrylate) or copolyester resins with anti-ammonia formulation, ensuring structural integrity and optical transmittance throughout their service life.
- IP69K Certification and Pressure Washing: Biosecurity demands rigorous disinfection protocols. The IP69K rating ensures that the luminaire is hermetic against industrial high-pressure hot-water cleaners (up to 80°C) and high pressure (100 bar) at close range.
- Passive Thermal Management Without Fins: Tubular or smooth-body heat dissipation designs that prevent the build-up of dust, feathers and droppings, facilitating water run-off and preventing overheating of the LED driver.
Photobiology and Photoperiod Control
Light regulates the endocrine system and circadian rhythm of animals, directly impacting feed intake, reproduction and stress levels. Our systems enable precision lighting management:
- Sunrise and Sunset Simulation: By means of dimmable drivers (DALI or 0-10V), the system gradually increases or reduces the luminous flux. This eliminates the shock of instant switch-on, reducing stress and mortality from piling (panic) in birds and improving herd comfort.
- Optimised Spectrum: Adjustment of the colour temperature (CCT) and spectral peaks (red/blue) according to species and rearing phase (gestation, finishing, laying), encouraging natural behaviours and reducing aggression (feather pecking).
- Absolute Flicker-Free Operation: The visual system of species such as poultry (hens, broilers) detects flicker up to 150-200 Hz, invisible to humans. The use of high-quality constant-current drivers eliminates the chronic visual stress induced by flickering.
Lighting Specifications by Livestock Type
| Species / Production Phase | Recommended Illuminance (lux) | Spectrum / Tone | Required Operational Control |
|---|---|---|---|
| Poultry (Broilers - Finishing) | 10 - 20 lux | 3000K - 4000K (Warm/Neutral) | Dimming 1-100% (Flicker-Free) |
| Poultry (Laying) | 20 - 30 lux | Spectrum with red peak (favours ovulation) | Gradual sunrise/sunset dimming |
| Pigs (Gestation / Finishing) | 40 - 50 lux | 4000K (Neutral) | Photoperiod timing (16h light / 8h dark) |
| Cattle (Dairy Production) | 150 - 200 lux | 5000K - 6000K (Cool) | Long-day simulation (increases milk yield) |
Frequently Asked Questions (FAQs) on Agricultural Lighting
Why isn't it advisable to install standard IP65 industrial waterproof battens in a farm?
Standard IP65 waterproof battens are designed for dust and low-pressure water (rain or sprinkling). On a farm, between-batch cleaning processes involve very high-pressure water and chemical disinfectants. In addition, if the enclosure is standard polycarbonate, ammonia vapours will degrade the material within a few months, causing seal failure and premature equipment failure.
What impact does flicker have on a poultry operation?
Birds have a critical flicker fusion frequency (CFF) much higher than humans. A low-quality LED luminaire that an operator perceives as continuous light is perceived by the bird as a constant stroboscopic effect. This produces a high level of metabolic stress, resulting in aggressive behaviours (cannibalism, feather pecking), lower feed intake and a sharp drop in productive performance.
How does DALI control optimise animal welfare and energy spend?
The DALI protocol allows precise dimming curves to be programmed. By simulating dawn and dusk over 30-45 minutes, animals are activated or prepare for rest naturally, avoiding the stress of abrupt on/off switching. Additionally, by dimming the light intensity to the levels strictly required by the animal's age, electricity consumption can be reduced by more than 60% compared to non-dimmable systems.
