UNILUX RECOMMENDS YOU

The good quality of light at the right time of day improves the feeling of well-being and intellectual performance.

1.How to choose your desk lamp?

The Industrial Medicine recommends a lighting of 450 Lux minimum. The European standard NF EN 12464-1* even up to 500 Lux for on-screen or reading work. It should be noted that an office equipped with fluorescent ceiling lights generally receives 200 to 300 Lux!

Local lighting is therefore essential to work under acceptable conditions.

* Standard NF EN 12 464-1 (European standard): Requirement for lighting in indoor workplaces

Avoid reflections :

The reflections are the N ° 1 enemy of a good visual concentration. They cause eye strain, headaches or musculo-skeletal disorders due to poor posture in front of the workstation, with consequences that can be disastrous.The use of an asymmetric lamp:
The use of a UNILUX asymmetric lamp allows:

  • neutralize much of the glare
  • considerably increase the illuminated area
  • to limit the contrasts between the different zones of the visual field

A suitable length :

The length of the arm also affects the quality of the illumination: the head of the lamp should ideally be 40 cm above the worktop. We must therefore avoid lamps with arms too short.

What type of bulb ?

  • Halogen lamps:

    It is an incandescent lamp but its tungsten filament is in a gaseous atmosphere containing halogen gas. The bulb is made of quartz that can withstand high temperatures

    Binding regulations that accelerate sales decline
  • Fluorescent lamps :
    Fluorescent lamps, commonly known as fluorescent tubes or neon tubes (although they do not contain neon), have a tube shape in which light is mainly emitted by layers of luminescent substances excited by a discharge electric.
    A constant demand, maintained by competitive prices
  • LED Lighting :
    LED lighting is very efficient and offers remarkable power and energy. The service life is 50,000 hours and they do not contain mercury and light up 100% as soon as it is turned on.

 Advantages and defects :

Each of these sources has advantages and defects, depending on whether one places oneself on the side of cost or comfort

2.The role of light
on our performance at work

The effects of light on our productivity :

We spend 90% of our time indoors, And about 8 hours a day at our workplace.

The light acts essentially on our biological clock, making sure that we sleep well, that we stay awake during the day and that we are at the best of our performances. However, in our modern world, we rarely go out outside and in the absence of sufficient daylight, our internal biological clock is deregulated. Fatigue, insomnia, and depression can be the result. Even a sufficiently lit interior is often perceived biologically dark and does not regulate our internal clock. A biologically effective artificial light can compensate for this deficit and stabilize our biorhythm.

What is circadian rythm?

The internal biological clock is a powerful control center By penetrating the body through the eyes, light plays a fundamental role in the regulation of circadian rhythms, that is to say those which are spread over a period of about 24 hours (awakening-sleep, variations of Body temperature and hormonal levels, meals, etc.).

The role of melatonin and serotonin in the circadian cycle:

Approximately 80 percent of the information is transmitted through our eyes. Thanks to the retinal glands in the eye, we also treat non-visual information. Influenced by the color of daylight, these cells control the secretion of serotonin and melatonin hormones in the brain, thus regulating our circadian rhythm (day and night rhythm). Melatonin makes us feel fatigue and reduces our activity; Serotonin, for its part, affects our mood and our dynamism.

How to optimize its circadian cycle!

Variations in lighting in terms of temperature either cold (color blue 5500K) or warm (color red2700K) during the day improve our well-being and therefore our performance. Since each person has their own biological rhythm, it is essential to disseminate optimal lighting adapted to the circadian rhythm of each user, by providing a personalized solution regulating his periods of activity and rest.

3.The benefits of light

Good light quality at the right time of day:

  • Decreases disturbances of circadian rhythm
  • Limits the risk of insomnia, irritability and mood disorders
  • Reduces lack of lack of concentration
  • Regulates the production of melatonin
  • Increases intellectual performance

4. Some basic notions

A lamp has an apparent color of light. It is the color temperature that is measured in degrees Kelvin (K). The higher the color temperature, the colder the light (in blue) and the closer it is to the daylight. On the contrary, the lower the temperature of the color, the more “hot” (in the yellows and reds).

  • In agreement with the Médecine du Travail, all our lamps have a color temperature between 2700 K and 5500 K

The color rendering index, designated by IRC or RA, indicates the ability of the light emitted by the source to restore the colored appearance of the illuminated object

  • All our lamps have an optimal color rendering of more than 80
