The light bulb originated from a scientist who wanted to invent something that would illuminate instead of a gas lamp. The first light bulb that could be invented was the incandescent bulb, after which the incandescent bulb was widely used all over the world.
but with the limitation of incandescent lamps Regarding the short duration of use and the tube is very hot Therefore, light bulbs have been developed continuously. until it became the LED bulb that we use today.
Today, LeKise takes me to get to know you. light bulb evolution From the past from 1879 to the present Before becoming an LED bulb today, what kind of bulb has evolved?
1879 An “incandescent lamp” made of tungsten generates high heat to induce a fire. The hotter, the brighter. It has a short service life and consumes power. We can see from being used to decorate a coffee shop. restaurant etc.
1890 "Moonlight Lamp" is not used today. because it is difficult to maintain and contains mercury toxic to the environment
In 1892, “Metal Haline Lamps” gave off almost the same amount of light as moonlight bulbs. have light balance close to sunlight but has a short service life
1926 fluorescent lamp More efficient and longer life than incandescent bulbs It also has lower heat. but must be used together with ballast and starter
1955, halogen lamp with 98% color accuracy, commonly used to illuminate jewelry. or product showcase
1976 CFL lamps are used to replace incandescent lamps. Helps to save electricity, has a long service life. many times more than incandescent bulbs
Year 2000 LED Bulb A60 Klassic provides more light and saves energy than before. have a long service life
The lamp has good heat dissipation. Mercury-free
With the features of LED lamps that meet all the needs of modern people whether it is about saving energy
It has a long service life. Safety because the material is designed to be environmentally friendly. Therefore it quickly gained popularity and spread throughout the world.
