Description Electrical engineers must take into account many factors when designing a lighting

system for an art museum. The importance of quality lighting is crucial; aspects to take into consideration are heat damage, true color, direction of light, controls and many more discussed in this report. When studying the Worcester Art Museum 19th and 20th Century European Exhibition there were several things I noticed about its lighting design. Below is a simple floor plan of the room, the room has no daylight and all lighting are from artificial lights.

Quality of Lighting

The human relationship to the effect of lighting is an important aspect in designing a lighting system. Adaptation to differences in brightness is performed in the human eye by receptors on the retina; adaptation from dark to light takes only seconds. The state of adaptation affects visual performance at any moment: the more light is available, the faster efficient visual performance can be restored. Given the south west entrance of the room has a daylight ceiling a transition space must be provided. Visual impairment occurs where the eye cannot adapt to differences in brightness fast enough. Brightness is the contrast to its surrounding objects. The phototropism phenomenon where people notice bright things can be used to highlight a specific painting. This is done with The Countess of Warwick and Her Son (1904) painting by John Sargent which is the largest painting in the East Wall.

The use of phototropism to lead people from one place to the next can be used to show obvious destinations. Lighting also defines a mood and ambience to a room. The first consideration was the wall color which was a yellow ivory which gave of a very warm surface reflectance in the room. This warm ambiance sets a certain mood to the room; its viewers which tend to be elderly can appreciate it. These three basic controllable elements: Intensity, Color, Texture emphasizes the importance of paintings. Another method of lighting is to create a contrast and variety lighting to reveal architecture and space. By layering lighting for specific tasks it creates a visual comfort for that task.

The different layers of light are achieved by categorizing each lamp. In 19th Century room the general lighting is done by the luminous ceiling, which the light provides a uniform

lighting to the room most common. The uniformity of the light distribution throughout the room is generally given by general lighting. Although is this room the general lights were not all used, you could see only part of the room was light with the luminous ceiling. The lighter surface of the paintings will in turn have a more reflectance throughout the room which will contribute to its general lighting. I suspect that the general lights which are from the luminous ceiling were off for this reason.

The most common category of light used was task lighting which are given by the luminaires on the ceiling mounted tracks. Task lights are used to provide as a direct source of lighting that allows views to see the details of an activity.

Color Effects All of the paintings in the room were oil on canvas and have primary white base color

meaning there are predominately lighter. As seen in Figure 2 the color balances of fluorescent lamp and halogen lamp in comparison with sunlight. The halogen lamps have a higher yellow/red spectrum and therefore give the warm mood to the room. Whereas the fluorescent have high peaks of green and blue the range from 380 to 560nm. As opposed to sunlight which has a normal curve with higher amounts of green in its spectrum.

A different way to measure color of lamps is through the Color Rendering Index, which

is the correlation from artificial lamp to sunlight which has an index of 100. In Figure 3 Correlated Color Temperature you can see the Fluorescent lamps have a CRI of 85. The higher the value the closer the true color of an object will be subject to that light.

Page 5: Worcester Art Museum Lighting Simulation

Another way is the Correlated Color Temperatures; this is the temperature in Kelvin that the lamp emits. The Kelvin scale illustrated that the warmer the apparent color of light source, the lower the number of kelvins.

Luminaire Luminous intensity (I) is the amount of luminous flux a reflector lamp or luminaire has. It

is measured in candelas (cd) or lumens (lm). Plotting the luminous intensity values at the different emission angles on a graph produces an intensity distribution curve (IDC) given in Appendix D

Analyzing the type of luminous ceiling in the gallery I concluded the general lights were Tubular Florescent Lamps with 120 Watts T8 Color Rendering Index (CRI) of 80 Correlated Color Temperature (CCT) of 4000K and 1000 Lumens.

In this gallery there were also track lights for accent lighting which are part of the accent category for lights. There were two types of accent light luminaries a spot light and a flood light wall wash. The spot light was smaller in diameter compared to the other which would make more sense with the candela distribution according to the lamp angle.

The flood light had a bigger diameter which I concluded to have a larger radius of degrees for its distribution of light. The accent light appeared to be Tungsten Halogen with Reflector PAR 30 and 38 for spot and flood lamps respectfully. The halogen light has CRI 90, CCT 3000K and 400lms. Given the distance of the lamp to the wall and the height of the ceiling there should be a 60◦ angle from the lamp to the painting. With an 8◦ beam angle of spot cylinder lamp there would be 60◦ foot-candle on the paintings.

Figure 3 Correlated Color Temperature

The Spot Luminaire has a Screen Filter with about 15% light blocked and 85% light transmitted. This type of filter as well as the ceiling height can protect the artwork from heat damage from the halogen lights. I also noticed that some of the luminaries were not all pointing directly in the center of the painting. The artworks presented in this gallery are from an Illusionist Movement period of time, these artwork tend to have a thicker volume and many wave or rippled on the painting surface. The problem with this is when the angle of the lamp is too high or too low that will cause a shadow on the art which will obstruct its true perspective. This is a good option to avoid glare on the surface of the painting.

There is also a black glossy sculpture head which has a lot of glare in its surface. I would recommend moving its location to a spot where there isn’t any direct illuminate or providing a diffuser filter to evenly distribute the light. To avoid this problem especially in painting that are darker the luminaire should have a direction angle right above the painting, this allows its task light propose yet providing an indirect light alternative.

Maintenance An estimate of room environment was to be considered clean and to have a semi-annually

cleaning interval. In the figure you can see the luminaire dirt depreciation (LDD) factor to be 0.9. Light loss factor (LLF), Lamp Lumen Depreciation (LLD), are given by type of lamp used, these factors are considered for coefficient of utilization, which measures how efficient a lamp is.

Maintenance of the paintings is also an important aspect of lighting in a museum. For oil paintings it is recommended to obtain an illuminance of 200 lux on its surface. Oil paintings are sensitive to spectral emission, and it falls under susceptible to light damage category. This can cause potential damage from invisible ultraviolet and infrared radiation directed into the materials. For this reason it a good reason 8 of the 17 paintings are covered in a thin layer of glass. This can although with the simulation not problems occurred with glare.

New Design The lighting control for the showroom is poor in the sense where it is only divided by half the room. I would provide an alternating control loop between the tracks to allow the exhibition to turn on a smaller quantity of lights yet still utilizing the whole display of the room. Also the general light system from the luminous ceiling is not currently being utilized; I would recommend a low voltage energy efficient florescent lamp and compensate that with the amount of head fixtures being used in the track. Providing a different type of luminaire as well as LED lamps will reduce energy consumption.

Utilizing alighting software DIALux 4.0 I was able to simulate the conditions of the current room. Given the inputs given above the obtained POV ray tracing outputs, which is the direction which a ray is computed by the model in the object surface. Refer to Appendix D&E for complete results of luminaire specifications, flux outputs, and isolines. The simulation did not include filters.

For the new design lighting system I’ve made the following changes. I changed the track luminaries from Lighting Technologies FHM/T 35 to Artemide M051513. I increased the luminous flux lamp level from 400 lm to 1400 lm. This allowed me to decrease the number of luminaires from 50 to 20 which is a significant number. Included in the changes was the power from 90W to 30W. The track was also moved back 4 ft. away from the paintings in the North and South Walls as seen in the ceiling grid in Appendix E. Given the Figure 5 below, x=y*cos(α) distance x from the wall became 11 and the light angle is 40@. This is in attempt to eliminate glare and wasted light.

Figure 5: Angle of luminaire

Page 8: Worcester Art Museum Lighting Simulation

The new design aims to maintenance the illuminance levels on the walls as homogeneous as possible. The general lights from the luminous ceilings were change from is luminous flux from 1000 lm to 600 lm and the power from 120W to 30W. Looking at the current design there is a few bright spots on the wall due to the direction of the luminaire. This can cause distraction from the paintings because of the contrast to its surroundings. One example is in the Figure 6 where the white spot is a false color rending of the amount of light on the location. An alternative is given by the new design in Figure 7

According to ASHRAE90.1_2007 the lighting power densities for museums should be 1.10 with the existing design there is 5.6, whereas the new recommended 1.05. According to Philips foot-candle recommendation in the Museum Category there should be range of illuminance 50-100 lux general and 200 lux on the paintings. The new design has average 165 lux on the paintings.

Below is a Table that shows the energy consumption and the change in energy with the new design. With this information the estimate number of hours of operations of those lights and the price per kW/hr. are giving below. The money saved per year is $668.50 Table 1 Energy Savings

19th Century Room / Maintenance plan

Regular maintenance is essential for an effective lighting installation. It is the only way to limit the light loss over the installation's life time. The minimum values of the illuminance specified in the EN 12464 are maintenance values, i.e. they are based on a new value (at installation) in a maintenance to be prescribed. The same is of course true also for the values calculated in DIALux. They can therefore be reached only if this basic maintenance plan is diligently carried out.
