Lighting - 2

a type of lamp where light is produced by the

heated wire filament. A filament is a thin piece of metal with high melting point

which glows or produce visible light with a current passing through.

• incandescent lamp
• LED lamp
• fluorescent lamp
• halogen lamp

a type of lamp where light is

produced by sending an electrical discharge through an ionized gas which can be

noble gas (argon, neon, krypton and xenon) or combination of these gases.

• Plasma lamp
• Gas-discharge lamp
• Fluorescent lamp
• Incandescent lamp

a type of lamp where light is produced by

passing the electric current through a semiconducting material (a diode) which

emits photons (light) through the principle of “electroluminescence”. It falls under solid-state lighting (SSL) lamps.

• LED lamp
• Halogen lamp
• Incandescent lamp
• Fluorescent lamp

a newer type of lamp which

produces light by cathodoluminescence where a beam of electrons is made to hit a

fluorescent phosphor surface. This type of lamp is still in is development phase to

compete with LED lamps in terms of efficiency

• Xenon lamp
• Electron-stimulated Luminescence (ESL) lamps

• Fluorescent tube lamp
• Incandescent lamp

Visible light is the only type of

electromagnetic radiation waves we can see where wavelength ranges from around ___nm to ___ nm

• 400, 700
• 500, 800
• 200, 900
• 300, 600

It describes how much power is converted to light. It refers to the amount of lumens

produced per watt. (lumens/watt)

• lighting efficacy

• Brightness ratio
• Light conversion rate
• Luminous efficiency

It describe how much power is converted to light. refers to the percentage of power that

is converted into something useful (visible light, in the case of lighting) and is usually unitless

• Efficiency
• Luminosity
• Radiance
• Efficacy

means a semiconducting device which only

allows flow of current in one direction only.

• Diode
• Capacitor
• Resistor
• Transistor

is basically a material with both

properties of a conductor and an insulator.

• conductor
• transistor
• superconductor
• semiconductor

considers the color rendition, color temperature, dimming ability and distribution of light so it adds to the aesthetics of a designed area.

• Quality of Light
