A LED filament light bulb is a 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). A halogen lamp (also called tungsten halogen, quartz-halogen, and quartz iodine lamp) is an incandescent lamp consisting of a tungsten filament sealed in a compact transparent envelope that is filled with a mixture of an inert gas and a small amount of a halogen, such as iodine or bromine. The combination of the halogen gas and the tungsten ... A 230-volt LED filament light bulb, with a B22 base. The filaments are visible as the four yellow vertical lines. A LED filament light bulb is a 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). Inventor Thomas Edison of Menlo Park, New Jersey first patented his carbon-filament lamp on 1 November 1879. His laboratory first produced promising results for this electrical lamp on 21 October 1879: a glowing carbonized thread which lasted for more than fourteen hours. Publicly demonstrating this invention at Menlo Park on 31 December 1879 ... The IV graph for a filament lamp shows the current increasing at a proportionally slower rate than the potential difference. IV graph for a filament lamp. This is because: As the current increases, the temperature of the filament in the lamp increases. The higher temperature causes the atoms in the metal lattice of the filament to vibrate more. The I–V graph for a filament lamp shows the current increasing at a proportionally slower rate than the potential difference; I-V graph for a filament lamp. This is because: As the current increases, the temperature of the filament in the lamp increases; The higher temperature causes the atoms in the metal lattice of the filament to vibrate more C-2F. filament shape (double support) ‘Crimp’ or better known as ‘Clamps’. Molybdenum Support wire. · The filament when mounted to the electrodes. Other methods of attaching the filament. to. The shaping of the electrodes beneath the bead varies for example: - seal, -seal bead butt or wedgebase. Wedgebase lamps ~ method. FILAMENT LAMP ~ INTRODUCTION Page 7 of 11 Input energy is known i n terms of Volts, Amperes and/or Watts. q Volts are the electro -motive force applied across the lamp terminals. q Amperes is the electrical current flowing through the filament of the lamp. q Wattage is the product of Volts x Amperes.
