Description

Fluorescent structure

technical field

The utility model relates to a fluorescent lamp structure, in particular to a fluorescent lamp structure in which an electronic circuit of a fluorescent lamp tube is assembled in an adapter so that the fluorescent lamp tube can be replaced independently when damaged.

Background technique

In traditional fluorescent lamps, the lamp tube is installed on a bracket with a rectifier and a starter. This kind of fluorescent lamp consumes a lot of electricity, is noisy in operation, and has high installation and maintenance costs.

General fluorescent tubes can be divided into ordinary fluorescent tubes and energy-saving lamp tubes. Ordinary fluorescent tubes have electrodes at both ends of the tube. There are two or three rings of tungsten wire on the electrode, and the electron emitting material is coated on the tungsten wire. There is an appropriate amount of mercury and argon gas in the tube, and the inner wall of the tube is coated with fluorescent material. When the power is input, the current flows through the electrode, the temperature of the tungsten wire rises, and the temperature of the electron emitting material also rises, and a large number of thermal electrons are released. , the hot electrons are pressurized between the two electrodes, flowing from the negative electrode to the positive electrode, causing the flow of current in the tube, hitting the mercury atoms in the tube, and generating energy to excite ultraviolet rays, and then the ultraviolet rays irradiate the fluorescent substances on the glass tube wall, which is caused by ultraviolet rays absorbing visible light Fluorescent tubes glow.

Energy-saving fluorescent tubes are different from ordinary fluorescent tubes in that three primary colors of rare earth phosphors are coated on the tube wall, and the three primary colors that are best for human naked eye color recognition ability: blue, green, and red are concentrated in three narrow spectrums to achieve a higher brightness. High luminous efficiency and strong brightness.

Common fluorescent lamp, as shown in Figure 1, is made up of fluorescent tube 11, rectifier 12, starter 13 and the lamp holder 14 that can fix the above components.

However, in the existing fluorescent lamp, the replacement procedure of the rectifier is complicated, and the starter needs to be installed separately from the lamp tube, which not only consumes power, but also the starter is easily damaged, and the lamp tube cannot be protected.

In view of this, the author researches and improves the way for this shortcoming, through research and improvement for a long time, finally has the generation of the present utility model.
