Oil Lamp (Ole Romer invents the oil lamp.)
An oil lamp is an object used to produce light continuously for a period of time using an oil-based fuel source. Oil lamps are a form of lighting, and were used as an alternative to candles before the use of electric lights. -
Kerosene Lamp (Ignacy Luckasiewicz invents the kerosene lamp.)
A kerosene lamp (also known as a paraffin lamp in some countries) is a type of lighting device that uses kerosene as a fuel. Kerosene lanterns meant for portable use have a flat wick and are made in dead-flame, hot-blast, and cold-blast variants -
Incandescent Light Bulb (Thomas Edison invents the incandescent light bulb.)
The incandescent light bulb or lamp is a source of electric light that works by incandescence, which is the emission of light caused by heating the filament. They are made in an extremely wide range of sizes, wattages, and voltages. -
Carbon Filament (Lewis Latimer invents the carbon filament.)
The carbon filament lamp was the first practical form of incandescent lamp, this material originally being favored because of the possibility to operate it at temperatures higher than any other electrical conductor that could be produced in filamentary forms at the time. -
Tungsten Filament (Willian D. Coolidge invented the tungsten filament.)
A tungsten filament is a thin strand of the metal which glows very brightly when an electric current is passed through it. Almost twice as dense as lead, it has the highest melting point of all the metals at 6192 ° F (3422 ° C); of all the elements, only carbon's melting point is higher. -
LED light bulbs (Nick Holonyak, Jr. invented the LED lights.)
An LED light bulb is a solid-state lighting (SSL) device that fits in standard screw-in connections but uses LEDs (light-emitting diodes) to produce light. LED bulbs use a semiconductor device that emits visible light when an electric current passes through it. -
Energy-Saving Light Bulbs (Ed Hammer invented the energy-saving light bulbs)
Energy saving lamps are sources of artificial light that employ advanced technology to reduce the amount of electricity used to generate light, relative to traditional filament-burning light bulbs. Examples of energy saving lamps include: Fluorescent lamps; i.e. regular and compact. a Light-emitting diode bulb. -
LED Filament Bulb( Ushio and Sanyo invented the LED filament bulb.
An LED filament light bulb is an LED lamp which is designed to resemble a traditional incandescent light bulb with visible filaments for aesthetic and light distribution purposes, but with the high efficiency of light emitting diodes (LEDs).
