Problems solved by technology

[0003] As we all know, the commonly used fluorescent lamps use electric heating filaments to excite the gas in the lamp tube to emit light. This kind of fluorescent lamps consumes high energy, has short service life, and wastes seriously pollute the environment. In order to solve the above problems, people have developed in recent years. Light-emitting diodes replace gas to emit light. Its basic structure includes a glass lamp tube with two open ends, two end caps assembled with the lamp tube openings, two conductive electrodes on the end caps, and a circuit board, constant current driver and Several LEDs, the circuit board is arranged axially in the glass lamp tube, the two
