The difference between incandescent lamp and fluorescent lamp

As we all know, the incandescent lamp we use every day was invented by Edison at the end of 19. For more than 100 years, incandescent lamps are basically Edison's original designs except for the improvement of manufacturing materials and technology. Incandescent lamps bring precious light to people and consume countless energy.

High temperature luminescence

Incandescent lamps emit light by heating the inner metal filament to a very high temperature (about 2000 degrees Celsius), so that the electrons in it jump to the energy level.

High temperature heating

Then the high-temperature filament emits light at the same time, so the bulb will get hot. 90% of the electric energy used by traditional incandescent lamps is lost in heating, and less than 10% is converted into light energy for people to use.

Luminous principle of fluorescent lamp

Fluorescent lamps excite the gas in the lamp tube to emit ultraviolet rays through filament discharge, and the ultraviolet rays excite the fluorescent powder in the lamp tube to emit white light. This luminous process consumes much less heat.

Heating conditions of fluorescent lamps

Although fluorescent tubes are very hot, they are far less hot than incandescent lamps.

Advantages of energy-saving lamps

The technology of small fluorescent lamps is mature, and their tubes are spiral, which does not occupy space and can be directly inserted into the lamp holder of incandescent lamps. The new energy-saving lamp only needs one tenth of electricity. At the same time, the life of energy-saving fluorescent lamps is about ten times longer than that of incandescent lamps, which further saves the losses in production and household expenses.

environmental problems

Fluorescent lamps contain mercury vapor, which is harmful to the environment. Now everyone is trying to reduce the mercury vapor content required for fluorescent lamps to shine as much as possible. Incandescent lamps contain lead and are also a source of pollution.
