How to size and choose your lighting?

A big change in lighting has been going on for a few years. The emergence and rapid growth of the LED (light-emitting diode) market has revolutionized the way we view and think about lighting.

What is good lighting?

Good lighting creates a visual environment that allows people to see, move safely and perform visual tasks efficiently, accurately and safely without causing eye strain. In order to ensure the lighting of the premises allowing the safety and the health of the workers, several parameters are to be taken into account while not neglecting the human factor.

A well thought-out lighting installation of led high bay light can contribute to the profitability of activity through financial gains through a reflection on operating and maintenance costs, productivity and environmental gains. Good room lighting combines high luminous efficiency, long life, and correct color rendition.

The lighting of the work premises must allow:


  • ·         Facilitate the execution of a task: this is the notion of visual performance.

Indeed, normal vision can only be exercised with a minimum of light. A good level of illumination allows good productivity within particular a fall of the errors, the accidents, and less visual fatigue.
  • ·         Ensure well-being: this is the fundamental notion of visual comfort.

Indeed in addition to the average level of illumination required, it is essential to ensure:
-          good quality of the light emitted by the sources
-          uniformity of illumination
-          And the balance of luminance to avoid dazzling in particular.

Natural light


The natural light remains today the most powerful light source, the most economical and best suited to our basic needs during the day.


How to get good lighting?

In order to obtain good lighting, it is necessary to carry out a calculation or study making it possible to determine:
  • ·         the number of bright spots
  • ·         the location of the light points
  • ·         the brightness and scattering angle of each luminous point
  • ·         Aspects of color temperature are also to be taken into account to achieve the desired environment.

Finally, we must ensure the well-being and visual comfort

A. Determination of luminance levels

The recommended lighting levels are given by standards expressed in lux. Lux is the unit of measure for luminance. A lux is equal to one lumen per m². After having determined the required level of illumination, the number of luminous points, their location and the lighting power required to reach the desired level of illumination are calculated.

B. Uniformity and visual comfort

Once the points of light have been defined, it is necessary to ensure that the lighting is homogeneous without the whole of the room and that the lighting does not generate a dazzle of discomfort. The level of glare is determined by the UGR. Once all these elements are established you can be assured that the chosen lighting will be well dimensioned, compliant with regulations and pleasant.

The influence of light on sleep. If for some time you have been waking up tired or groggy, the explanation may be to look further than "not being in the morning." After eliminating medical reasons, here are some questions to ask yourself: ·          Do you have bright or cold lighting in your bedroom ? ·          Do you sleep with the television on? ·          Are you on your computer or tablet within a few hours of going to bed? If you answered "yes", be aware that these factors can cause poor sleep. Circadian rhythm and blue light The circadian rhythm is better known as the internal clock: a cycle of 24-hour biological, mental, and physiological processes. These processes include cognitive performance, mood, and most importantly, sleep and wakefulness. Without a doubt, light is that the greatest impact on our sleep cycle. This is be...

Change the power supply to replace a halogen spotlight with a 12 V LED

Image
Change the power supply to replace a halogen spotlight with a 12V LED Many chandeliers, ceiling lights or recessed spotlights are equipped with halogen bulbs type G4 or MR16. These installations operate with halogen-type bulbs, powered by an electronic transformer providing a current between 11 and 18 volts. Why replace a halogen spotlight with a 12V LED? In order to save money, save time or simply replace a defective light bulb, it is interesting to replace the energy-intensive 12V halogen with a G4 LED bulb or MR16 LED bulb with equivalent light but a consumption of 7 to 10 times less. How to replace a 12V halogen strip   light with an LED ? It is relatively simple and fast to make this replacement, nevertheless, you will need simple notions of electricity: Hardware needed:   screwdriver, cutting pliers, wire stripper, electrical connection terminal, MR16 socket, LED power supply. 1. Determine the base of the bulb in question 2. Remove the bulb 3...
