4. INTRODUCTION OF LIGHTING
The human eye can see well over a wide range of lighting conditions,
but a machine vision system is not as capable. You must therefore carefully
light the part being inspected so that the machine vision system can clearly
'see' them.
The light must be regulated and constant so that the light changes
seen by the machine vision system are due to changes in the parts being
inspected and not changes in the light source.
You will want to select lighting that 'amplifies' the elements of the
part that you want to inspect and 'attenuates' elements that you don't want
to inspect. In the left picture, poor lighting makes it difficult to read the
letters on this part. In the right picture, the lighting has been selected to
clearly show the lettering.
Proper lighting makes inspection faster and more accurate. Poor lighting
is a major cause of failure in machine vision inspection systems.
In general, the available or ambient light is poor lighting and will not
work. For example, the overhead lights in a factory can burn out, dim or
be blocked, and these changes might be interpreted as part failures by
the machine vision system.
Selecting the proper lighting requires some knowledge and experience.
Our distributors and lighting vendors will be able to do an analysis of the
parts you want to inspect and recommend proper lighting.
5. DIRECTION AND DISTRIBUTION OF LIGHT
A luminaire (lighting fixture) emits light in one of three directions-
downward, upward, or multidirectional- and in one of two distribution-
concentrated or diffuse.
Direct glare is prevented by both this restricted spread and the shade of
the human eyebrow. Upward light usually covers a large area of the ceiling;
the light reflected from the ceiling is low luminance and is unlikely to cause
distracting glare. Multidirectional light is emitted in all direction, but it
cannot emit much of its output sideways without causing objectionable
glare.
Upward and downward light is emitted in patterns that vary from
narrow to wide. Concentrated Distribution focuses light in a narrow pattern;
diffuse distribution disperses light in a wide pattern.
When located in law ceiling, concentrated downward beams-with
spread of 30or less-create areas of high luminance on the floor ith dark area
in between.
Concentrated downward (direct)
distribution.
14. GLARE AND SPARKLE
Glare is also a function of luminance area. Although a small area
of luminance is tolerable, a larger area of the same intensity becomes
uncomfortable. It is desirable to reduce luminance intensities the area
luminance becomes more dominant in the field of view.
15. TYPES OF LIGHTING
Provides an area with overall illumination. Also known as general
lighting, it radiates a comfortable level of brightness without glare and
allows you to see and walk about safely. In some spaces such as laundry
rooms, the ambient lighting also serves as the primary source of task
lighting.
It can be accomplished with chandeliers, ceiling or wall-
mounted fixtures, recessed or track lights and with
lanterns mounted on the outside of the home. Having a
central source of ambient light in all rooms is fundamental
to a good lighting plan.
Helps you perform specific tasks, such as reading, grooming,
preparing and cooking food, doing homework, working on
hobbies, playing games and balancing your check book. It can be
provided by recessed and track lighting, pendant lighting and
under cabinet lighting, as well as by portable floor and desk
lamps.
Task lighting should be free of distracting glare and shadows and
should be bright enough to prevent eye strain.
Adds drama to a room by creating visual interest. As part of an
interior design scheme, it is used to draw the eye to houseplants,
paintings, sculptures and other prized possessions. It can also be
used to highlight the texture of a brick or stone wall, window
treatments or outdoor landscaping.
To be effective, accent lighting requires as least three times as
much light on the focal point as the general lighting surrounding
it.
Accent lighting is usually provided by recessed and track lighting
or wall-mounted picture lights.
16. TRACK LIGHTING
Track lighting is a method of lighting where light fixtures are attached anywhere
on a continuous track device which contains electrical conductors. This is in
contrast to directly routing electrical wiring to individual light positions. Tracks can
either be mounted to ceilings or walls, lengthwise down beams, or crosswise
across rafters or joists. They can also be hung with rods from especially high
places like vaulted ceilings.
Typical systems have line voltage running through a recessed track. The track may
have more than one live conductor, so that multiple switched circuits can be used
to control different fittings on the same track. Installers will place the tab of the
connector on the fixture to one side or the other when attaching it to the track.
17. WALL SCONCES
A sconce is a type of light fixture affixed to a wall in such a way that it uses only the
wall for support, and the light is usually directed upwards, but not always. It does not
have a base on the ground. For this reason, lighting fixtures will need an electrical box
to be installed. The word applies both to traditional forms of torch, candle or gas
lighting, but also to modern electric light sources affixed in the same way. Modern
fittings are more often called wall lights or similar terms, especially if the light source is
wholly covered by glass.
Sconces can be placed on both the interior and exterior walls of buildings. In pre-
modern usage, these usually held candles and torches respectively. Historically, candle
sconces were often made of silver from the 17th century, with porcelain coming in in
the 18th.
Modern electric light fixture sconces are often used in hallways or corridors to provide
both lighting and a point of interest in a long passage. Sconce height in a passageway is
generally 3/4 of the distance up the wall as measured from the floor to the ceiling, and
the distance between sconces on the wall is generally equal to the distance of the
sconces from the floor, often alternating sides of the passageway. Sconces are typically
installed in pairs or other multiple units to provide balance. They can be used to frame
doorways or line a hallway. Swing arm sconces are often placed next to a bed to
provide task lighting for reading.
18. PENDANTS/DROP LIGHTING
A pendant light, sometimes called a drop or suspender, is a lone light fixture that
hangs from the ceiling usually suspended by a cord, chain, or metal rod. Pendant
lights are often used in multiples, hung in a straight line over kitchen countertops
and dinette sets or sometimes in bathrooms. Pendants come in a huge variety of
sizes and vary in materials from metal to glass or concrete and plastic. Many modern
pendants are energy-saving low voltage models and some use halogen or
fluorescent bulbs.
A billiard or island light is a longer pendant fixture, usually with long fluorescent or
multiple incandescent bulbs, used over kitchen islands and billiard tables. They are
sometimes considered a type of chandelier.
It is a key component to understanding Architectural lighting design and sometimes
associated with interior design.
19. CHANDELIERS
A Chandelier is a decorative ceiling-mounted light fixture, a distinct type of
pendant light. Chandeliers are often ornate, and normally use incandescent light
bulbs, though some modern designs also use fluorescent lamps or even LEDs.
Crystal chandeliers have more or less complex arrays of crystal prisms to illuminate
a room with refracted light. Chandeliers are often located in hallways, living rooms,
dining rooms, and recently in bathrooms and bedrooms.

20. DESK/TASK LAMPS
Often task lighting refers to increasing illuminance to better accomplish a specific
activity. However, the illuminance level is not the only factor governing visibility.
Contrast is also important, and a poorly positioned light source may cause contrast
reduction, resulting in loss of visibility. Therefore, it can be argued that the most
important purpose of task lighting in the office is not increasing illuminance, but
improving contrast. Because task lighting provides focused light where needed,
general lighting can be reduced.
Different strategies for task lighting exist. The three main approaches are:
Localized average lighting, where a lamp supplies both ambient light and task light
Freely adjustable task light such as a gooseneck, balanced-arm lamp, or swing-arm
light.
Other instances of task lighting are in machinery, where a specific work area needs
illumination, and in workshops, where a task light may illuminate the actual
working area. Special instances of task lighting are examination and operation lights
for medicine and surgery, as well as the dentist's lamp. Task lamps are also used for
many home tasks such as sewing, reading, small repairs, model construction, crafts,
writing, and many other activities. The actual task may range from very small up to
about as far as you may reach with your hands or available tools. Lighting of larger
areas is beyond the scope of task lighting.
21. BUFFET LAMPS
A buffet lamp, or candlestick lamp, is a tall lamp with a shade that is commonly
found on dining buffets and narrow console tables. They usually have a thin
base with a thick, sturdy bottom. They are taller than the average accent or
table lamp.
Buffet lamps are well-known space-savers that can also be elegant accessories
that add light to a room. They can be used as reading lamps. They are available
in a large number of styles and are made from a variety of materials, including
brass, nickel, natural wood, jade and silver. Styles vary from extremely simple
to intricate.
