Each culture leaves its unique mark in the vast garden of world cultures, which coexist and converge with each other. Darkness is the world's original natural environment, since the birth of mankind, people have been trying to create light, from the most primitive beginnings to the most sophisticated technology, the lamps of each era, a sign of the development of social productivity, is the crystallization of the combination of art and science and technology, they drive away from the darkness where there is no sun and give us sunlight. May 21, on the occasion of World Culture Development Day, we come to talk to Let's talk about: the origin and development of lamps and lanterns.
Evidence of the first lamps used by early humans dates back to 70,000 BCE. At that time, there was no metal or copper available for making lamps, and their construction was simple: just a shell or a hollow rock with a piece of moss soaked in animal fat and burned with a flame.
Since then, mankind began to use man-made pottery, marble, and metal as the body of the lamp, to extend the flame burning time and make it concentrated, but also often add wick; 1801, Humphry Davy invented the gas safety lamp, he will be two wires connected to the battery, and the other end of the wire connected to charcoal, but this lamp is the use of electrodes between the discharge to produce arc light, the principle is similar to the lightning, the light line is too strong, high cost, and not suitable for civilian use.
As time went on and new sources of energy were discovered, new kinds of lamps were invented. The kerosene lamp was introduced to Germany in the mid-19th and early 20th centuries. It is a container filled with kerosene in which the wick or shade is immersed to burn. The container has a glass chimney or globe that protects the flame from air currents. For people born in the 1960s and 1970s, the kerosene lamp is no stranger to the effect of kerosene lamps, although not as great as electric lamps, because of the simplicity of production, lower cost of use than candles, and very stable lamp many benefits to the public in up to 40 years still can not bear to give it up.
It wasn't until 1879 that Edison made an electric lamp with practical value, which worked by passing an electric current through a filament that heated it and produced light. If by modern standards, these lamps lasted a short time and were inefficient and fragile, but were a great leap forward and laid a good foundation for future development. 1891, originated in Europe under the Dutch brand Philips, was established under Gerard and his father Frederic. However, because of the low penetration rate of electric lamps and the high cost, some poor families still use kerosene lamps until the 1980s, kerosene lamps were officially retired from the stage of history. Now, kerosene lamps can only appear in the minds of the elderly as a memory.
Incandescent lights illuminate the 20th century, while LED lights illuminate the 21st century. LED this electronic component appeared as early as 1962, but the early can only emit low luminosity of red light, after the development of other monochromatic light versions, but the conversion efficiency is low, only 16LM / W, equivalent to only 4% of the electrical energy into light energy, the other electrical energy is converted into heat; to 1900, the emergence of fluorescent lamps, conversion efficiency increased significantly to 70LM / W. And the currents, to this day white LEDs exceed 300LM/W, and the light emitted has been throughout the visible, infrared and ultraviolet light.
The history of the development of lamps and lanterns is a voluminous art scroll, after thousands of years of development, electric lighting technology continues to progress, the function of lamps and lanterns also gradually from the beginning of a single practice to a combination of practical and decorative.
Today, we produce many kinds of lights with different materials, different power supplies, different colors, and different purposes. For example, space can be divided into living room shelf lamp, tripod lamp, sofa lamp; according to the scene can be divided into a bedside lamp, reading lamp, sleeping lamp; according to the atmosphere and star lamp, neon lamp, sunset lamp. Sunmory as a collection of R & D, production, processing, sales in one lamp brand, reasonable prediction of the future development trend of lamps and lanterns will tend to energy saving, environmental protection, quality, can be inherited, collection value of these aspects, and Sunmory is also looking forward to generation after generation of innovation, looking forward to you to explore with us the new development of the world of light.
