The document discusses the luminance requirements for lighted signage, particularly focusing on LED technology as a replacement for traditional light sources. It highlights the lack of consensus standards for signage luminance and the negative consequences of excessively bright signs, such as increased energy use and light pollution. Through laboratory experiments, the study evaluates human preferences for sign brightness under various background luminances and viewing distances, aiming to establish optimal design criteria for energy-efficient and visually effective signage.

How does lighting affect energy efficiency?

It means being smarter with your lighting making better use of natural lighting, turning off lights when not in use, dimming lights, using sensors and controls or upgrading to lights that are more energy efficient. Energy efficient lighting uses less energy without compromising on brightness and quality.

What is efficacy in lighting?

Energy Usage Comparison LED (Light Emitting Diode) lights are the most energy efficient among the four types. LEDs use only about 20-25% of the energy consumed by an incandescent bulb to produce the same amount of light. CFL (Compact Fluorescent Lamp) lights use about 70% less energy than incandescent bulbs.

Why is efficacy important in lighting?

Why is it important? A light engine with a high efficacy will be able to produce more lumens per watt of energy used. This means that light engines with a higher efficacy are more efficient and are cheaper to run than a light engine with a lower efficacy with the same lumen output.

What does the term efficacy mean when used to measure the energy efficiency of lighting?

Efficacy is a measure of how well a light source converts electrical energy into visible light. It is expressed in lumens per watt (lm/W) and is used to determine the efficiency of a light source. In simpler terms, efficacy is a measure of how efficiently a light source produces visible light.

What is high efficacy lighting?

Understanding Light Efficacy Light efficacy can otherwise be described as how much useable light (or useful) a light source provides per unit of electrical measure. It measures the amount of visible light produced by a light source.
