LED Bulbs
• “LED” is the abbreviation of  
“light-emitting diode”. It is a  
semiconductor light source  
which could emit light when 
 a current moves through it.
• An LED bulb is a lighting bulb 
 that uses an LED chip to  
convert electronic energy  
into light.

lamp) is a fluorescent  
lamp, using a tube curved 
 or folded to fit into the  
base of the bulb which  
has a compact electronic  
ballast in it.

Incandescent Bulbs
• An incandescent bulb is an  
electric light that emits light 
 with a filament wire heated 
 to a high temperature until  
it glows by consuming  
electrical energy.
• The incandescent bulb must 
 be the earliest electric bulb 
 in human history; however, 
 energy experts claim that  
the incandescent bulb  
should be replaced by other 
 more energy efficient bulbs 
 and become a thing of the  
past.
