Task Lighting

Task Lighting, a crucial part of an ergonomic workplace, refers to a light source used to illuminate a particular task. Generally task lighting refers to office lighting, where various work areas, need to be illuminated according to the purpose of that area. In today's work environment, two contrasting viewing requirements need to be satisfied, a light source that will not be too bright to work on the monitor screen but not too dim to read documents and papers. LED (light-emitting diodes) lights, the latest innovation in lighting technology, are ideal for task lighting as they are a directional light source, emanating light in a particular direction. These LED task lights also last longer and are more energy efficient.       

 

 

Ergonomic Task Lighting is a very important aspect of a healthy working environment. The right lighting solutions help create the experience of comfortable, flexible and stimulating working environments. Innovative ergonomic lighting products and concepts aim to provide optimum lighting conditions with individual needs in mind.

  • The Ergonomic Lighting at your workstation depends on the type of job you are involved in. Do use bright lights with a large lighted area while working with printed materials. Limit the brightness of light for computer tasks.
  • The user should be able to adjust the position and angle of the light sources, as well as their intensity levels.
  • To direct or diffuse the light, it should have a hood or filter.
  • The base of the light should be large enough to allow a variety of convenient positions or extensions
  • It is ideal to place lights parallel to your line of sight in different rows.
  • Try to use light diffusers so that you can do the desk jobs like writing, reading papers etc. while limiting direct brightness on the computer screen.
  • You need to have good desk lighting for proper illumination while writing and reading tasks thus limiting brightness around monitors.
A task light is the best way to obtain individually adjusted illumination of the workplace. To get the best effect out of ergonomical task light you have to position it correctly. An ergonomical task light distributes the light asymmetrically over the work area and provides maximum light approximately 35 - 40 cm from the shade.
  • If you work at a computer, look for luminaries which distribute light in a way that is not creating glare or reflections on the screen, provide an even and flicker-free light distribution, are easy to adjust, and are stable.
  • If you have a large work area, look for luminaries which will illuminate large work surfaces, provide an even and flicker-free light distribution, are easy to adjust, are stable and distribute the light in a way that is not creating glare or reflections
  • If you work at a less spacious working area, look for luminaries which give smaller but still effective light output, are multi functional, are stable and distribute the light in a way that is not creating glare or reflections.

Recommended light levels:
Working at a computer - 500 - 750 lux
Normal desk work - 500 - 1000 lux
Control work - 750 - 1500 lux
Reading, drawing and vision demanding work - 1000 - 2000 lux
General lighting usually provides approx.    300 -500 lux


How to choose the correct light source?  There are certain things to consider also when you are choosing a light source:
  • Light color
  • Life cycle
  • Light output
  • Color rendering
  • Economy
