It is predicted that by 2016 LED lighting will be approximately 50% of

the residential lighting marketplace. This rapid adoption means that

LEDs will soon become the primary lighting source in single-family

and multi-family construction. This course will focus on the LED and

Solid State Lighting technologies and design concepts that are

leading the way in the re-shaping of residential lighting design. The

efficiency, small scale and ubiquity of these new technologies are

providing designers with opportunities to integrate LED lighting into

innovative residential lighting design concepts using multiple LED

lighting layers. The course also will cover updates on the latest and

most innovative LED product introductions for residential

applications.

Sponsors

1. To better understand the key benefits of using LED lighting in

residential applications.

2. To better understand how LED technology is positively impacting

lighting design objectives when using lighting layers.

3. To better understand the specific benefits of LED lighting in

kitchen and baths.

4. To better understand the primary specification issues that

designers and architects must define when selecting and

applying LED decorative and architectural lighting in residential

applications.

5. To analyze specific case studies of successful LED lighting

applications.

is the lumen.

Correlated Color Temperature

(CCT)

A measure of the color appearance

of a white light source.

CCT is measured on the Kelvin

absolute temperature scale.

Correlated Color Temperature

The Color Temperature Dilemma

The color rendering index (CRI) scale is used to compare the effect of

a light source on the color appearance of its surroundings.

A scale of 0 to 100 defines the CRI.

A higher CRI means better color rendering, or less color shift.

LEDs fall within the category of

Solid State Lighting

Solid-state lighting (SSL) includes devices that use diodes to create lighting, including:

Light Emitting Diodes (LED)

Organic Light Emitting Diodes (OLED)

The terms SSL and LED are often used interchangeably.

LED Facts

What is a diode?

• A diode is a very simple

type of semiconductor.

• A semiconductor is a

solid material with a

varying ability to

conduct electrical

current.

LED Facts

The semiconductor die consists of a chip of semiconducting

material treated to create a structure called a

p-n (positive-negative) junction.

LED Facts

When a voltage is applied across the electrodes the current flows

from the anode (P side) to the cathode (N side).


LED Facts

• When an electron meets a hole at the P-N junction it falls in to a

lower energy state.

• The excess energy of the electron is emitted as a Photon

(Photons)

LED Facts

• LEDs emit heat mostly in

the form of conduction.

• To dissipate this heat, LEDs

are mounted on heat-

conducting material called a

heat sink.
