How bright are you when it comes to lighting? Luminocity, your central Indiana outdoor lighting expert, has compiled a list of interesting lighting facts that will help you shine at your next trivia event. Test your own knowledge with our fun quiz:
1. How do LEDS generate light?
A. LEDs generate light through a process of intense friction, causing the material to heat up and glow.
B. LEDs generate light through electroluminescence, where electrons recombine with holes in a semiconductor material, releasing energy in the form of photons.
C. LEDs use small, internal mirrors to reflect and amplify ambient light, creating a brighter glow.
D. LEDs contain tiny, pressurized gas chambers that emit light when electricity passes through them.
Answer: B. LEDs convert electrical energy directly into light energy through the interaction of electrons and holes within a semiconductor material.
2. What is the most energy-efficient type of lighting?
A. Incandescent bulbs are the most energy-efficient because they produce the most light.
B. Halogen bulbs are more energy-efficient because they are brighter than LEDs.
C. LED lighting is generally considered the most energy-efficient type, often lasting 25 times longer than incandescent bulbs.
D. Florescent bulbs, the first energy-saving bulbs, remain the most energy efficient.
Answer: C. LEDs lead the way in energy efficiency, longevity, durability and versatility.
3. How is lightbulb brightness measured?
A. Lightbulb brightness is measured in lumens.
B. Brightness is measured by the weight of the filament.
C. Brightness is measured by the volume of light produced.
D. Brightness is measured by the amount of electricity it consumes.
Answer: A. Many people think that lightbulb brightness is measured in watts. So, a 60-watt bulb will be brighter than a 40-watt bulb, right? Not really. A watt is a measurement of how much energy is being used. A lumen, on the other hand, measures how much light comes from the bulb.
4. What is the name of the phenomenon where light is redirected by a surface?
A. Diffraction.
B. Refraction.
C. Absorption
D. Reflection
Answer: D. Reflection is the phenomenon where light is redirected by a surface. The talented lighting designers at Luminocity will use reflection judiciously during installation, to create light and shadow the emphasizes your home’s unique beauty.
5. What does illumination refer to?
A. The amount of light emitted by a source in a specific direction.
B. The amount of light falling on a surface.
C. The color appearance of a light source.
D. The intensity of the light source.
Answer: A. Illumination in lighting refers to the amount of light falling on a surface. It’s a measure of how much luminous flux (the total amount of light emitted by a source) is spread over a given area. Proper illumination is crucial for visibility, aesthetics, energy efficiency and safety.
6. What is the name of the phenomenon where light waves interfere with each other?
A. Refraction
B. Diffraction
C. Reflection
D. Absorption
Answer: B. Diffraction refers to the bending or spreading of waves as they encounter an obstacle or pass through an opening.
7. Who invented the incandescent light bulb?
A. Thomas Edison
B. Nikola Tesla
C. Benjamin Franklin
D. Albert Einstein
Answer: A. While others contributed to the development of the light bulb, Thomas Edison is widely credited with inventing the commercially viable incandescent light bulb.
8. What is the name of the phenomenon where an object appears to be a different color when viewed under different light sources?
A. Color rendering
B. Color temperature
C. Color shift
D. Color distortion
Answer: C. Color shift describes how the perceived color of an object can change depending on the color temperature and spectrum of the light source.
9. What is the best way to prevent glare from outdoor lighting?
A. Use dimmer bulbs.
B. Direct the light downward.
C. Install lights closer to the ground.
D. Use multiple lights
Answer: B. Shielding fixtures and directing light downwards towards the intended area minimize glare and reduce light trespass onto neighboring properties.
10. Who should you rely on for the best outdoor lighting?
A. You can handle it yourself with a few Youtube videos and some lighting from the internet.
B. Your local neighborhood handyman can install outdoor lighting.
C. Your landscape company will handle the lighting design.
D. A certified lighting designer like Luminocity.
Answer: D. Put your home in its best light with a custom outdoor lighting design by Luminocity. Luminocity is home to two of only five Certified Low Voltage Lighting Technicians (CLVLT) in Indiana, as well as the only Certified Outdoor Lighting Designer (COLD.)
