  • Lamp efficacy

    Lamp efficacy

    Ensuring the lamp efficiently converts electricity into light (lm/W).

  • Ballast classification

    Ballast classification

    Controlling the electricity supply to the lamp (Energy Efficiency Index).

  • Luminaire distribution

    Luminaire distribution

    Controlling light emission using optics which bend and shape the light to the correct location.

  • System efficacy

    System efficacy

    The use of a high efficacy light source combined with precision optics results in a high system efficacy, producing maximum light output for minimum energy input.

  • Presence/absence detection

    Presence/absence detection

    Presence: Lights automatically turn on/off with movement. Absence: Lights automatically turn off and must be manually switched on.

  • Daylight detection

    Daylight detection

    Artificial lighting which responds to the natural light conditions.

  • Constant illuminance

    Constant illuminance

    A function designed to produce correct light levels for the duration of the maintenance period.

  • Task-scene setting

    Task-scene setting

    Allowing the user to set scenes and adapt the lighting to different tasks.

  • Timed off

    Timed off

    In contrast to metal halide lamps, LEDs react immediately to controls. Lights can therefore be automatically turned off during unoccupied hours and turned on immediately when required. As a result, no energy is wasted lighting the tennis courts when they are not in use.

  • Task lighting

    Task lighting

    Careful design of the lighting installation concentrates light onto the playing surface and immediate surrounds. This ensures a well-lit environment and highly efficient use of light with little waste.

  • Zoning of lighting

    Zoning of lighting

    Lighting is zoned according to area use.

  • Maintenance schedule

    Maintenance schedule

    Maintenance must be performed in response to product age, performance and environment.

  • Waste light

    Waste light

    Eliminating waste light which does not hit the intended target.

  • Reflectance

    Reflectance

    Taking advantage of light which is reflected from the surface within the space.

  • Visible smart metering

    Visible smart metering

    Results of actions can be quickly seen as increased or decreased energy use to encourage responsible energy consumption.

Thorn Energy Partnership reduces energy consumption at multi-sport complex

Polisportiva Saliceta San Giuliano is a large multisport complex in Modena, Italy. Open seven days a week, it is home to a wide range of sports and fitness activities, from football to cycling, weight training to beach volleyball. Its facilities include seven tennis courts, six squash courts, five football pitches and lots more.

With the previous lighting for the three indoor tennis courts comprising 8x400W metal halide floodlights, the energy efficiency was poor. The LENI (Light Energy Numeric Indicator) was 80 kwh/ m2/year, producing more than 1900 kg of CO2/year. The light quality was also low with the average illuminance at 130lux.

Polisportiva Saliceta San Giuliano sought to improve both the energy efficiency and the lighting. It therefore turned to its local Thorn Energy Partner (TEP) in the Emilia Romagna region for a solution.

HiPak Pro LED slashes energy by 35%

Andrea Benussi, Chief Lighting Designer at Thorn Italy, says: "Our Thorn Energy Partners, including installer Borsari Luciano, were delighted to work with PolisportivaSaliceta San Giuliano. Although our HiPak Pro LED luminaire is traditionally used in industrial applications, it offered the ideal solution in this instance.

"Robust and low maintenance, HiPak Pro LED is 35% more energy efficient than the floodlights it replaces. Dedicated individual LED optics ensure precise light control while an integral PIR sensor and DALI dimming maximise energy savings. Every year, HiPak Pro LED will save 52 kwh/m2/year and 1250kg of CO2.

"Importantly, HiPak Pro LED is positioned to avoid glare(UGR<20) and enables players to correctly evaluate distances by providing very good task lighting (300lux) combined with high 3D visibility of the ball and opponent.

"The vertical plain along the field also has excellent uniformity with no dark shadows. This ensures players can see clearly, which is particularly important because the ball travels at such a high speed. Overall, the lighting scheme is fully compliant with EN15193 class III but with a level of uniformity higher than class I requirements.

"With a dedicated body profile and onboard thermal management system, we estimate HiPakPro LED will provide Polisportiva Saliceta San Giuliano with a long and low maintenance 30-year lifetime."

Feedback from the players shows they find the light very comfortable with no glare. They also say the brightness of the light creates a more dynamic playing and competitive environment.
