Description

A LED fluorescent lamp without lamp feet

technical field

The invention relates to the field of LED fluorescent lamps, in particular to an LED fluorescent lamp without lamp pins.

Background technique

Fluorescent lamps generally refer to lamps composed of lamp tubes and lamp legs at both ends. Fluorescent lamps and LED tube lamps are commonly used. The lamp holder of the fluorescent lamp has a lamp pin plug-in structure, and the plug-in structure has a shell and a conductive reed contacting the lamp pin. The fluorescent lamp sockets used in the early days were inserted into the rotary lamp sockets. There were two rectangular jacks on the panels of the lamps. The jacks were fixed pins for connecting to the necessary power supply input. When disassembling the fluorescent lamp, it is used to compress the spring so that the lamp pin can be inserted into the socket. It is inconvenient to align the holes when installing the lamp tube, which brings a lot of trouble to the installation. Due to frequent expansion and contraction, failure of the spring in the lamp holder or poor contact between the lamp holder and the lamp tube itself, the failure rate of poor contact between the lamp holder and the lamp tube is extremely high. With the development of technology, in order to facilitate the disassembly and assembly of fluorescent lamps, the lamp holder of the fluorescent lamp has been changed into a rotating lamp holder, that is, there is a radial groove and an annular groove on the shell, and the outer wall of the annular groove on both sides of the radial groove has a Contact piece, the two lamp pins are moved in from the radial groove, and then the lamp tube is rotated 90° according to the axis, so that the two lamp pins slide on the annular groove respectively and contact with a contact piece to turn on the power supply. However, because the rotation method, especially the rotation angle, is difficult to grasp, the disassembly and assembly of this fluorescent lamp is still relatively troublesome. The specific manifestations are: first, the contact copper sheet between the lamp foot and the lamp holder is not aligned correctly, causing the circuit to fail; If the rotation angle is improper during installation, the lamp tube will fall off; the third is that the connection between the lamp tube and the lamp cap is a cylindrical surface according to the axis. or damage the lamp holder.

Modern lighting mostly uses LED light source technology, and its lighting effect is better. However, most of the current LED lamp tubes are used in conjunction with the structure of the original fluorescent lamp holder, that is, the two pins at both ends of the lamp tube are still used to connect electricity. In order to maintain the same appearance and structure as the early fluorescent lamps, people tried to design the driving power of the LED in the lamp tube. In this way, the appearance of the LED lamp tube is the same as that of the traditional fluorescent lamp, so that the LED lamp tube can directly replace the original fluorescent lamp tube.

Due to the safety certification requirements of countries such as Europe and the United States, the double-ended wiring method of traditional fluorescent tubes needs to be changed to the single-ended wiring method. The following problems exist in the process of replacing the original fluorescent tubes with LED tubes. Traditional tubes use electronic ballasts and magnetic ballasts: 1. Due to the existence of the original electronic ballasts, there are special requirements for LED drivers, and Different brands of electronic ballasts have different electrical properties, which has caused a lot of trouble for directly replacing traditional fluorescent lamps with LED fluorescent lamps. 2. The aging of the original lamp pins often cause breakage when replacing with LED fluorescent lamps and need to be replaced. 3. If the structure of the traditional fluorescent lamp is an inductive ballast, but after adding a power factor correction capacitor, it will not work normally to replace it directly with an LED fluorescent lamp. 4. The original wires, lamp pins, electronic ballasts, capacitors, transformers, starters, etc. may have reached the end of their service life. As long as one of the above-mentioned components has a problem, the LED lamp will not work normally. 5. Because people want to directly replace traditional lamp tubes, the structure of LED fluorescent lamps has great limitations. Therefore, from the perspective of lighting function, LED fluorescent lamps currently on the market cannot completely replace traditional fluorescent lamps because the brightness is very limited.
