What is the reason why the light doesn't work?

The reason why the lamp tube is not bright: 1, the tungsten filament of the lamp tube is burnt out; 2. The circuit breaker is turned on; 3. The switch fuse is blown; 4. Line problem. Where there is light, there is human civilization. Tens of thousands of years ago, human beings knew to use the fire of nature to keep out the cold, barbecue and light. More than 3000 years ago, humans began to carry candles with simple lamps and write the history of civilization. From rough stone lamps to bronze lamps, ceramic lamps to modern electric lamps, the historical changes of lamps are deeply branded with the times and are also the epitome of social economy and culture.

Extended data:

T5 tube is a kind of fluorescent lamp (or fluorescent lamp, fluorescent tube, cathode fluorescent lamp), with a diameter of 5/8 inch, about 16 mm, belonging to a kind of gas discharge lamp. It uses electricity to activate mercury vapor in argon or neon to form plasma, which emits short-wave ultraviolet rays and makes phosphorus emit visible fluorescence for illumination.

Cathode fluorescent lamps are generally made of glass, with sockets at both ends connected to the power supply to fix the position of cathode fluorescent lamps. Fluorescent tubes are gas discharge light sources, which are divided into T 12, T 10, T8, T6, T5, T4, T3, etc. In terms of pipe diameter, T8, T6 and T5 are the mainstream at present.

T5 fluorescent tube, in particular, is replacing T8 fluorescent tube at a faster speed because of its advanced technical performance, high luminous efficiency and good lighting quality and effect.
