  • 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

    Combining optical and thermal control within the luminaire (luminaire lm/W).

  • 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

    Automatic cut-off can be installed to turn all lights off during unoccupied hours.

  • Task lighting

    Task lighting

    Lighting task areas with the correct amount of light.

  • 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


    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.

Dentist clinic lighting sets new standards

A technically intriguing refurbishment scheme has just been just completed by Thorn Denmark for the School of Dentistry in Aarhus.

It is the forerunner of many similar schemes now being planned by the University of Aarhus for its teaching clinics, where the introduction of special fluorescent luminaires is bringing about a new era of quality.

In conjunction with the School's consultant ALECTIA, an experimental installation using recessed fluorescent luminaires with special micro-prismatic panels was installed at a clinic. After a successful trial period, the scheme associates drew up a specification which Thorn successfully met.

The custom made luminaires are designed to provide a high quality of light in terms of colour, an Ra of over 90 enables dentists to select the right colour plastic for fillings, uniformity and freedom of glare. They replace a 30 year old scheme with yellow, glaring diffusers.

The average illumination level has risen from 700 to 1,000 lux - meeting the exacting requirements of Danish Standard DS 705:2002 - Artificial lighting in dental consulting rooms. Fitted with twin 54W T16 tubes, the new design requires half the number of luminaires needed previously, so permitting major savings in energy and capital costs. Each luminaire has intelligent DALI control to reduce operating hours.

The lights also feature extreme maintenance flexibility, with a smooth, sealed, surface for easy cleaning and the ability to quickly change lamps.

Five hundred luminaires have been fitted in four teaching hospitals and orders have been placed for a further six renovation projects next year. There’s a new look to the exterior too, and it’s all down to the use of Dyana LED road lanterns.

Architect for the Aarhus clinic was Erik Moller.
