Light bulbs are a necessity in our daily life. It increases the light and helps us see things clearly, more accurately. The light bulb originated with scientists. who wanted to invent something that would illuminate instead of a gas lamp. The first light bulb that could be invented, 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's moonlight bulb Not currently used because it is difficult to maintain and contains mercury toxic to the environment.
- Year 1892 Metal Halide Lamp giving out almost twice as much light than a moonlight 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 bulbs are more bright and save energy than before. have a long service life The lamp has good heat dissipation. Mercury Free.
