Professor James McKernan, Victor Wolters, Renee Brode and various
industry partners have teamed up to provide the York University
community with an LED theatrical lighting symposium. Their goal is to
increase familiarity with the evolving world of LED technology and look
at how this technology can be an effective design tool for theatre and
dance lighting designers.
They are providing two sessions. The first
session will include a mediated discussion with manufacturing
representatives as well as one on one time with LED products and
industry representatives. For the second session York Faculty, industry
professionals and Lighting designers will have the opportunity compare
and contrast LED lighting technologies by combining it with traditional
tungsten/halogen theatrical lighting fixtures.
The first session on January 14th is open to all, the second session on the 15th is by
invitation only, if you wish to attend the second session or if you have any questions, please contact Professor James McKernan at
Below is an outline and schedule for the two sessions:
Thursday Jan 14 - Show and Tell
Open to all
The purpose of this session is to showcase a range of LED products in
the marketplace to the performance community at York University.
Included in the day will be a moderated discussion with the product
representatives aided by a review of preselected questions (see below
for a draft sample of the questions). Following the discussion there
will be an opportunity for people to have hands on interaction with LED
products and meet with the product representatives one on one.
Draft Questions for Moderated Discussion. (Thursday Jan 14 - 18:30-19:30)
- 18:30-19:30 / Moderated Q&A in FFT with students, faculty and staff
from Theatre, Dance, and FAPF.
- 19:30-21:00 / Hands on open house with LED products and product reps
1. Can you explain the life cycle of the LED's used in your fixtures
including the predicted life expectancy of the LED.. Does the
performance of the LED shift as the fixture ages (ie change in colour
temperature, intensity, etc). What happens to the fixtures when the
LED's burn out? Are the LED clusters replaceable, the same way as a
traditional theatrical fixture bulb? If you put a new cluster into an
older fixture will the LED's perform in the same way (ie - be the same
colour, brightness, etc as the older clusters)?
2. Can you explain the concept of "bidding" in manufacturing LED's.
What are some of the challenges that the bidding system brings to
manufacturing a consistent product? How do you chose the right LEDs to
put into your fixtures?
3. Fixture noise is always a concern for lighting in theatrical
situations. As LED's get brighter and hotter how do you plan on dealing
with heat in fixtures used in performances were fan noise is undesirable?
4. We have seen manufactures deal with the colour mixing in LED
fixtures in a verity of ways including a conventional tri-light LED
system as well as a number of other Multi-cell designs. How do you
decide how many LED should be in a cluster? How do these discussion
effect colour rendering, creation of "white" light, brightness, and ease
5. One challenge for theatrical lighting designers using LED fixtures is
consistency from one LED manufacturer to another. This is particularly
evident when touring a show using "in house" equipment where one theatre
has purchased one manufactures product and a second theatre has product
from a different manufacture. Is there any discussion in the industry
on developing standards? Are there suggestions for ways of controlling
LED fixtures in a touring situation to insure consistency in colour and
intensity when using products from different manufactures?
6. One of the challenges facing theatrical designers using LED lighting
is the ability to control the light coming out of a fixture to the area
that it is being light. Conventional theatrical lighting fixtures have
tools to help with this like shutters and barn doors. Are there ways of
controlling light from LED fixtures in the same way?
7. We want to make sure we give you the opportunity to talk about what
you are doing that is new and exciting and/or is there something we
have missed you would like to bring to this discussion.
Friday Jan 15 - Compare and Contrast
By invitation only
This session will engage professional lighting designers in a
discussion about using LED lighting fixtures in conjunction with
traditional theatrical lighting equipment. Invitees to include York
community lighting designers and technicians as well as other selected
professional lighting designers. These designers will look at a verity
of lighting applications with an emphasis on combine incandescent and
LED lighting in performance situations.
- 9:00-10:00 / Set up demo - looking at the various kinds of LED fixture
and differences in hanging, addressing, patch, etc.
- 10:00-11:00 / Focus demo - spend time looking at the process of
focusing LED fixtures and how this compares with traditional fixtures focus.
- 11:00 - 12:00 / Lunch
- 12:00-15:00 / Q-ing - Incorporate LED lighting as an element within
traditional incandescent theatre/dance lighting design. This section
will focus on creating tableaus and be divided into three parts - colour
mixing, "white" light, and dimming.
- 15:00-17:00 / Designers use breakout rooms to continue discussion /
participate in seminar.
