The development of modern technology has brought great changes to the mindset and skills of people in many industrial fields, especially the lighting industry. The changes that occur are not only related to the lighting product market but also lighting manufacturer, from small to large scale.
In modern life, the need for reliable and energy-efficient lighting is generally considered as important as the need for clean water and internet connection. But have you ever wondered what the evolution of lighting has been like over the years?

For your information, there are three important aspects of the evolution of lighting: the luminaire, the fuel source, and the technology used to produce the light. The following is a more detailed explanation.
In the past, humans relied on the main natural light sources or sunlight for lighting. Generally, the architecture of the building at that time had special characteristics on the roof or dome to be able to take advantage of sunlight as lighting, for example, the Pantheon during the Roman Empire.
Illuminating Engineering Society data states that the first lamp was invented about 70,000 years ago. These lamps are called torches and are made of hollowed-out stone, shells, or similar non-combustible materials that have been filled with combustible material, such as dry wood or grass-covered with animal fat, and then burned to light. Over time, even though its appearance changed to a torch with a handle or mounted on a building wall, the basis for making it was the same.
The introduction of the wick to produce candles was perhaps the most significant advance in lighting technology since the invention of fire. According to the data, it was the Greeks and Romans who introduced the wick to the Egyptians. In Egypt, itself have been found candle holders dating from 4 centuries BC.
Gas lamps were first invented in England in 1790 and were soon introduced to America. Over the next few decades, the use of gas lamps in America evolved into street lighting in many urban areas of America. The development of gas lamps to support this infrastructure proves not only progress in terms of the lighting industry but also the production of hydrocarbon fuels (production and distillation of coal and petroleum).
The electric lamp was first invented by Humphry Davey and is in the form of an arc light. However, the electric light bulb and all its supporting infrastructure were invented by Thomas Edison in 1879. Initially, Edison invented an incandescent light that could be lit for 13 and a half hours. However, not long after that, he managed to find a carbonized bamboo filament that can burn for 1.200 hours.
The production of incandescent bulbs then dominated lighting manufacturers. Until 1904, fluorescent lights appeared as a new rival. Although it requires non-standard connectors to operate and high voltage, fluorescent lights are considered more efficient. However, the popularity of this lamp did not last long due to the presence of a mercury vapor lamp which is considered compatible with standard electrical infrastructure and very efficient.
In the twentieth century, the use of High-Intensity Discharge (HID) lamps, such as mercury-vapor, metal-halide, and high-pressure sodium, was in great demand. This type of lamp works by sending an electric current between two metal electrodes through a glass tube filled with inert gas, producing visible light emission.
Interestingly, the presence of Light Emitting Diode (LED) lamps at that time also attracted market attention. This type of lamp has significant differences from HID lamps. LED lamps are solid-state (SSL) lamps that produce light by converting electric current using a semiconductor and do not use a glass housing like traditional lamps. In addition, this lamp has many advantages over other types of lamps, for example, it has a life span of 2-4 times longer than the average of its competitors, produces high-quality light, and is much more efficient.
In the past, light manufacturers worked relying on human labor. Because, to produce lamps, they still use hard tools and die sets, with punch and brake press specially designed for each particular product.
Nowadays, light manufacturers generally use machines that operate digitally, for example, large machines that can make patterns into sheet metal all day and night, laser fabrication machines, press brake machines, and 3D printing and prototyping machines. However, human labor is still needed, especially those who are experienced with electronics manufacturing and are responsible for monitoring and maintaining machines.
Digital systems play a very important role in helping lighting manufacturer produces the best quality products and reach the global market. Just like SDD Light. This light manufacturer based in Guangdong, China, specializes in LED solar light is on a global scale because it has implemented a digital production system according to the rules of the international standard quality assurance system. You do not need to doubt the quality of the product. If you're looking for a reliable LED solar lighting manufacturer, SDD Light is the answer.
