Transcript of 4 Illumination

Work Environment Design: ILLUMINATION
Pablo García Castillo
Aim
Illumination Study
Plants with good environmental properties, PRODUCE much more than the ones without them
To ensure a confortable and safety work environment for the operator
More ROI
Productivity increases
More safety
Less absenteeism
Worker's zest is increased
24% of work accidents rely on bad lighting factors (IMSS, 2009)

Poor artificial illumination causes 25% of common injuries and increases 75% of operators falls
Types of Luminaires
Direct Lighting

Indirect Lighting

Direct-indirect Lighting
Light emanates spherically in all directions from the source
The amount of light striking a surface, or a section of this sphere, is termed illumination and is measured in lux
The clarity with which the human sees something
Visibility
Visual fatigue related then to mental fatigue (monotony) causes less attention to the activity, headache, eye irritation ---> no more quality and productivity
Illumination most common problems
Is the excessive brightness in the field of vision, decreasing visibility so that additional time is required fot the eyes to adapt from light to darker conditions.
Glare
Filters
Obstacle between the source and the viewer
Matte surfaces
Reorienting the work surface or task
Solutions against Glare
Shades
The worker must be placed so that shades are not interfering with his tasks
Color
Color and texture have psychological effects on people
Reduce sharp contrasts
Increase reflectance
Highlight hazards
Walls must be darker than the ceiling
NOM-025-STPS-2008

It must be done every two years or less if activities, tasks, or workplaces are modified
