By the end of the eighteenth century, candles and traditional oil lamps—which had been in use since antiquity—began to be superseded by a new class of oil-burning lamps that, thanks to a series of improvements, provided considerably more light than any previous form of indoor lighting. Plant oils (Europe) or whale oil (United States) fueled these lamps until, by the middle of the nineteenth century, they were gradually replaced by a petroleum derivative called kerosene. Though kerosene lamps remained popular until well into the twentieth century (and in some places until today), by the late nineteenth century they began to be supplanted by gas and electrical lights. -

Photonic Lantern Illumination Source
PLIS (Photonic Lantern Illumination Source): an efficient light source for light sheet microscopy Jordi Andilla1, Rodrigo Becerra1,2, Gustavo Castro1, Pablo Loza-Alvarez1 1ICFO, The Institute of Photonic Sciences Mediterranean Technology Park, Av. Carl Friedrich Gauss, num. 3 08860 Castelldefels (Barcelona), Spain 2INAOE, Instituto Nacional de Astrofísica, Optica y Electrónica Luis Enrique Erro No. 1, Puebla, 72840, México E-mail: [email protected], [email protected] KEY WORDS: Light sheet fluorescence microscopy, Scattering Imaging, Photonic Lantern. 1. MOTIVATION Fluorescence Microscopy has been crucial in the modern understanding of biological molecular processes. More specifically, techniques like laser scanning confocal microscopy or light sheet microscopy [1] provided high resolution up to the diffraction limit. These last techniques have been possible thanks to the good emitting properties of lasers. However, for many high-resolution microscopy applications some of the characteristics of lasers are not needed or even produce undesired effects. The narrow wavelength bandwidth is not needed in the fluorescence microscopy due to the wide spectral excitation band of the fluorophores. In fact, LED sources and super-continuum lasers result in a more gentle excitation of the fluorescence and therefore in the production of high S/N images. Furthermore, in certain techniques, based on elastic scattering imaging, TIRF or light-sheet microscopy, the temporal coherence of the lasers is not only not required but also it produces undesired interference patterns or structures that affect the image quality. On the other hand, for all those imaging techniques, spatial coherence is a strong requirement to obtain the diffraction-limited illumination necessary for obtaining high-resolution images. -
Lamp Basics Compiled.Pdf
Lamp Basics Lost-in-Time Museum Lamp Fuel One of the earliest types of lamp fuel was animal tallow, usually rendered from beef or mutton fat. Normally solid at room temperatures, it had to be heated to stay liquid. Lamp designs began to emerge in the late 1700’s using lighter fluids, which could travel vertically up a wick and produce a brighter, more efficient light. Whale oil, already used in candle making, was found to be an excellent oil for this new type of lamp. As the market grew, prices for whale oil soared. Burning fluid and camphene, two substitutes for whale oil, were used as early as the 1830’s, but were dangerous due to their flammability. Their use became obsolete as kerosene became more affordable. Kerosene, first produced in 1846 by distilling cannel coal, was commonly referred to as ‘coal oil’. The word "Kerosene", a registered trademark in 1854, eventually became a generic name used by all refiners. While safer and cleaner than burning fluids and camphene, it was expensive and not affordable to the everyday consumer. Kerosene distilled from petroleum revolutionized the lamp fuel market. As production methods became more efficient in the 1860’s, this new type of kerosene, which produced a brighter and cleaner light, gradually became the fuel source used by the general populace. An improved distribution network for natural gas and electricity, along with the technological advancements they made possible, led to the end of kerosene as a primary fuel source. Kerosene is now mainly used for residential heating and as an additive for insecticides and aviation fuel. -

Basic Principles and Techniques of Lighting
Lighting 102 Basic Principles and Techniques of Lighting by John J. Rankin VINCENTLIGHTING.COM 1 /" -Ê"Ê-/ Ê/ The following criteria should be used to determine if stage lighting is necessary and effective. £°Ê 6- /9 Visibility is a very important function of stage lighting. The audience should be able to see exactly what you want them to see, or not see those things that should remain hidden. Therefore, we might rename this function as “selective visibility.” An example of selective visibility can be found in the play, Wait Until Dark by Frederick Knott. A blind woman is terrorized by a murderer hiding in her apartment. To even her odds against him, she smashes all of the light bulbs thus plunging him - and the audience - into darkness. The action is revealed verbally and occasionally visually with flashlights, matches, and a very surprising source of light at the climax of the play. Ó°Ê , 6 /" Ê"Ê", Similar to selective visibility, revealing the form of the actor, dancer, or speaker will make them stand out from their background. Using techniques described later in this article, you will be able to make the subject appear natural and be the focus of attention for the viewers. For example, when lighting a ballet it is important for the stage lighting to reveal the form of the dancers. The audience wishes to see the dancers move through the space and stand apart from the background. Lighting ballet has been described as “lighting fish in an aquarium.” Light is the same as water in this metaphor. -
