(Q4) Lighting

Question 1

Artificial Lighting

Answer 1

• Incandescent
• Fluorescent
• LED (Light Emitting Diode)

Question 2

Natural Lighting

Answer 2

• the sun: white light
• Usually not used in funeral homes; diffused or indirect sunlight will enter the room

Question 3

Incandescent Lighting

Answer 3

• Lighting that operates by running electric current through a wire filament which emits light
• Filament is enclosed in a glass bulb
  with air evacuated

Question 4

Fluorescent Lighting

Answer 4

• 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

Question 5

LED (Light Emitting Diode)

Answer 5

• Diode with two terminals is encased
  in epoxy
• Electric current is sent from one
  terminal to another which activates a
  semiconductor to emit light

Question 6

Lighting in the Preproom

Answer 6

• 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

Question 7

Lighting in the Viewing Room

Answer 7

• 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

Question 8

LED Lighting in the funeral home

Answer 8

Because of the range of color temperatures LED lighting can create, they may be used in both the prep room and the viewing room

Question 9

Lighting in Preproom vs Viewing Room

Answer 9

• 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

Question 10

Color Rendering Index

Answer 10

• 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

Question 11

Types of lighting fixtures

Answer 11

• Torchiere lamps
• Flood lights
• Spotlights
• Cove lighting

Question 12

Spotlights Use

Answer 12

• 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

Question 13

Types of Lighting

Answer 13

• Direct lighting
• Indirect lighting
• Diffused lighting

Question 14

Direct Lighting

Answer 14

Source of light is pointed directly at the object being illuminated

Question 15

Indirect Lighting

Answer 15

• Source of light is bounced off of a medium (ceiling or wall)
• The object is illuminated by the bounced light softening the appearance

Question 16

Diffused Lighting

Answer 16

• 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

Question 17

Methods of Color Illumination

Answer 17

• Additive Method
• Subtractive Method

Question 18

Additive Method

Answer 18

• 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)

Question 19

Subtractive Method

Answer 19

• 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)

Question 20

Colored Illumination Affects Objects

Answer 20

The perceived color of an object will
change when the illumination color
changes

(Ex. Red cube under blue light becomes
black)
