(Q4) Lighting Flashcards
Artificial Lighting
- Incandescent
- Fluorescent
- LED (Light Emitting Diode)
Natural Lighting
- the sun: white light
- Usually not used in funeral homes; diffused or indirect sunlight will enter the room
Incandescent Lighting
- Lighting that operates by running electric current through a wire filament which emits light
- Filament is enclosed in a glass bulb
with air evacuated
Fluorescent Lighting
- Lighting created by a Bulb/tube that is filled with mercury vapor gas
- Electric current causes mercury
vapor to release UV rays - UV rays cause a phosphor coating on
inside of tube to glow, emitting light
LED (Light Emitting Diode)
- Diode with two terminals is encased
in epoxy - Electric current is sent from one
terminal to another which activates a
semiconductor to emit light
Lighting in the Preproom
- Commonly, fluorescent lighting is used
- Room is bright for maximum visibility during embalming
- This light is considered “cool”
- Brightness is not conductive to viewing deceased
Lighting in the Viewing Room
- Commonly, incandescent lighting is used
- Lighting is much dimmer and soft
- This light is considered “warm”
- Atmosphere of calm and comfort, similar to living room at home
LED Lighting in the funeral home
Because of the range of color temperatures LED lighting can create, they may be used in both the prep room and the viewing room
Lighting in Preproom vs Viewing Room
- Prep room: cool and bright
- Viewing Room: warm and dim
- Be mindful when cosmetizing in the prep room because lighting in the viewing room will change the appearance
- Whenever possible, cosmetize in the viewing room under the same lights
that the family will see the deceased
Color Rendering Index
- The ability of a light source to faithfully show the true color of an object
- Light source is compared to that of “ideal” white light, like that of the sun
- A scale of 0 - 100; Higher the number, the better representation of the true color
Types of lighting fixtures
- Torchiere lamps
- Flood lights
- Spotlights
- Cove lighting
Spotlights Use
- Use colored spotlights to control
the appearance of the deceased - Spotlights on a dimmer allow for maximum control
- A dimmer allows for mixing of different lights for a wide range of colors
Types of Lighting
- Direct lighting
- Indirect lighting
- Diffused lighting
Direct Lighting
Source of light is pointed directly at the object being illuminated
Indirect Lighting
- Source of light is bounced off of a medium (ceiling or wall)
- The object is illuminated by the bounced light softening the appearance
Diffused Lighting
- Light is softened by passing through a medium at the light source
- This soft light creates soft shadows
Ex: sunlight is diffused through clouds on an overcast day
Methods of Color Illumination
- Additive Method
- Subtractive Method
Additive Method
- Creating light colors by adding
multiple light sources, each with
a different hue - Start with multiple colored lights, add them together to make desired hue; Eventually creates white
(Ex. Red + Green + Blue = White)
Subtractive Method
- Using one light source and color filters
- Filter out (subtract) unwanted
colors to create the desired hue
Start with one white light, subtract (filter)
unwanted colors to make desired hue - If all the light is filtered, it will
turn black (absence of light)
(Ex. White - Red - Green = Blue)
Colored Illumination Affects Objects
The perceived color of an object will
change when the illumination color
changes
(Ex. Red cube under blue light becomes
black)
