Lights enable humans to see the fascinating things in this world.Human beings are highly grateful for natural sunlight. The invention of light bulbs has led human beings to have a great life.Before the invention of light bulbs, it became quite difficult for people to work at night. Hence, this invention was a necessity for people and has helped humans in many ways. The light bulb has helped humans to be safe and have confidence. There were a total of 22 different light bulb inventors before Thomas Edison.The average lifetime of household lights being used in homes is around 1,000 hours. The record for the longest-lasting lighting bulb, which is in the Livermore Pleasanton Fire Department in California, is a light that has not been turned off since the year 1901!The History Of The Electric Light BulbThe man who took credit for inventing the electric bulb is none other than the well-known scientist Thomas Edison. The invention of the light bulb took place in the year 1879. Though the electric lamp was known to be invented by Thomas Edison, the idea was not entirely his. However, the patent was signed in the year 1880. This invention of the light bulb was the first practical illumination tool for humans.However, way before Thomas Edison’s light bulb invention, there were scientists who invented electrical power and electric light.Types Of Electric BulbThere have been many different types of electric bulbs, and many are in use today. The various types of electric bulbs which help in lighting up the environment are as follows.Incandescent light bulbs are the most traditional early light bulbs and have been in use for a long time now. Incandescent bulbs do have the drawback of high energy consumption. An incandescent bulb houses a wire filament which is heated until it glows. It is more of an electric light bulb and functions in a similar way to other incandescent lamps. A current is supplied through the electric light bulb in an incandescent lamp through metal filaments, which are twice as efficient as carbon filaments. Early bulbs were not this efficient.Halogen incandescent bulbs are next-generation bulbs that were invented to help humanity achieve a greener environment.Fluorescent light bulbs were invented for large-scale use in buildings where more bright light was needed.The world has seen how compact fluorescent bulbs or the CFLs have made everyone’s lives better. This was the first highly energy-efficient light bulb to be invented.LED light bulbs are the latest technological invention in the world of light bulbs. They are a little more expensive due to their high energy-saving abilities and the safe quality of light that they produce.The major difference between LED and incandescent bulbs is that the former do not have light bulb filaments.Parts Of Electric BulbsThere are a total of 10-12 items used while making an electric bulb. The very first one is, of course, the bulb, which is an outer covering made up of soda-lime glass. This acts as a protective shield for the inner parts of a light bulb.The next one, which is the second most well-known part, is the filament of the bulb. The filament has a major function of conducting electricity in the bulb, and it also helps to produce light at high temperatures. The filament is made up of tungsten.There are also some different kinds of wires which are used inside a bulb. These are known as lead-in wires and support wires. The lead wires are supported by the support wires. The lead wires help in carrying a current between the base and the thin filament.Another part of the bulb is called the stem press, which is used for dissipating light and also helps in protecting the wires.The next one is the exhaustion tubes or the vacuum tube. As the name suggests, this wire is used for exhausting the gases that are inside the bulb.So, it is now clear that there are some gases inside a light bulb as well. These are argon and nitrogen gases that keep the filament intact. Otherwise, a filament would evaporate.There is a heat deflector that is used in the Light Bulbs, which does not allow the gases to deposit in the neck of the bulb.The last but by no means least important part of any electric bulb is the use of a fuse. A fuse is a backup that helps in the protection of the entire bulb if the filament suddenly breaks.Likewise, an incandescent bulb has a tungsten filament inside, and the high melting point of tungsten filaments helps the incandescent light glow.Since we know that light bulbs light up by electricity, can you think of something else that would be helpful in providing light to light bulbs? Of course, there is a battery, which helps in providing light by creating the energy of motion.Another common question among people is about why a tungsten material is used for making the filament. Tungsten is highly resistive. This means that the melting point of tungsten is high, and since light bulbs generate so much heat, it is used as a filament because it will not meltdown. Apart from all of these, the material tungsten even has a low vapor pressure and also high tensile strength. Also, tungsten is a lot cheaper than other metals.Which bulb is best for the eyes?Since there are many different types of bulbs used to produce lights, the color of the light emitted is also different. There are warm lights, electric lights, brighter light bulbs, electric arc lamp products, halogen bulbs, natural light, yellow lights, white lights, energy-efficient long-life bulbs, incandescent lighting, fluorescent lights and even those used exclusively for decorative lighting. They run on an electric current.There are also invisible light and arc lamp concepts. Carbon arc lights have carbon rods as electrodes. LED lamps are known to be the most damaging lights, which can cause the risk of cataracts and macular degeneration. Even LEDs can cause retinal changes, which can make the quality of vision much worse. However, it is known that the warm light generated by CFLs is good for the eyes as it does not emit too much ultraviolet light. Even halogens are considered a good option for the eyes.The light-emitting diode is highly considered to be an electric bulb. LED bulbs, however, are known to use less electricity than any other light bulbs. However, LED bulbs, as earlier mentioned, are not good for the eyes and can cause many problems to the eyes, especially in the retina.As earlier mentioned, there are many different types of lights like warm lights, natural lights, daylight, and many more. These different types of lights have different effects on the eyes. So, if you want to know which is better when choosing between daylight and soft white light, then it highly depends on the type of environment that you are using these lights in. For example, if you want to use daylight, then it is better to use it for a commercial environment as it has some bluish tints. Soft white light becomes a better choice to use for homes or residential areas.Another confusing issue while choosing light colors is between yellow and white light. Many people might be wondering which one is better. After all, everyone wants to have the best things in life. Yellow light can be much better for the eye, which effectively helps in protecting your retinas. It is good for reading purposes as well. However, white lights can be a better option, but a study revealed that these white lights are not good for the body. Some researchers even stated that white lights can decrease the amount of melatonin in the body.While there are eight most common light bulb shapes, smart light bulbs for constant electric light and reduced early bulb blackening are preferred now. You may have seen fluorescent lamps, glass bulb types with visible light and a carbon filament at home. Speaking of carbon filaments, they were used in the early stages. Tungsten is used now.Lights have been an essential part of human lives. Humans are thankful for the invention of light bulbs or the light sources which enable a human to see this beautiful world. The invention of light has been a great blessing to human life.
Lights enable humans to see the fascinating things in this world.
