Clipper lighters; on the left, the flint system which has been removed from the orange one. Clipper is the brand name of a type of refillable butane lighter, designed by Enric Sardà and owned by Flamagas S.A. [1] since 1959. The lighters are mostly produced in Barcelona, with others manufactured in Chennai and Shanghai. [2]
An exploded-view drawing is a diagram, picture, schematic or technical drawing of an object, that shows the relationship or order of assembly of various parts. [1]It shows the components of an object slightly separated by distance, or suspended in surrounding space in the case of a three-dimensional exploded diagram.

Like fluorescent lamps, HID lamps require a ballast to start and maintain their arcs. The method used to initially strike the arc varies: mercury-vapor lamps and some metal-halide lamps are usually started using a third electrode near one of the main electrodes, while other lamp styles are usually started using pulses of high voltage.
Like the European modular furniture, display cabinets, ceiling tile grids, etc. they were designed for, these are based on multiples of the 300 mm (11.8 in) "metric foot" instead of the 12 in (305 mm) imperial foot, but are all 37 mm (1.5 in) shorter to allow space for the lampholder connections within the 300 mm modular units, and for much ...
A Sankey diagram of energy losses in a fluorescent lamp. In modern designs, the biggest loss is the quantum efficiency of converting high-energy UV photons to lower-energy visible light photons. Only a fraction of the electrical energy input into a lamp is converted to useful light.
George Inman later teamed with General Electric to create a practical fluorescent lamp, sold in 1938 and patented in 1941. [6] Circular and U-shaped lamps were devised to reduce the length of fluorescent light fixtures. The first fluorescent light bulb and fixture were displayed to the general public at the 1939 New York World's Fair.
Shunt clippers, where the diode is shunted across the load resistance. The diode capacitance affects the operation of the clipper at high frequency and influences the choice between the above two types. High frequency signals are attenuated in the shunt clipper as the diode capacitance provides an alternative path to output current.
