Lamp adapter mechanism

technical field

The utility model relates to a conversion joint mechanism of a lighting device, in particular to a conversion joint mechanism of a lamp tube.

Background technique

T5 and T8 are commonly used lamp tubes. Generally speaking, the specifications of fluorescent lamp tubes are classified according to the outer diameter of the lamp tube. One inch (25.4 mm) is divided into 8 equal parts, and each part is divided into T1, and T8 is 8 etc. Points, exactly one inch (25.4mm) outer diameter of the lamp tube, and T5 is only 5 equal parts, so less than one inch, smaller than T8, so T5, T8 refers to the outer diameter of the lamp tube, generally It is said that the thinner the lamp tube, the higher the luminous efficiency (under the same power). In addition to the different tube diameters, the luminous efficiency, power consumption, color rendering and price of these lamps are also different.

At present, cheap T8 lamp tubes are mostly used in places such as homes, schools or companies. However, the strobe times of T8 lamp tubes are only 60 times per second. Eyes are prone to fatigue, and it will also cause vision loss; compared with T8 lamps, T5 lamps flicker as high as 30,000 to 50,000 times per second. It greatly reduces the burden on the user's naked eyes, and under the same power, the T5 lamp has higher brightness than the T8 lamp due to its good luminous efficiency. After the advent of high-power T5 lamps, more and more users want to use high-power T5 lamps that are not harmful to the eyes and save electricity. However, the diameter of T5 lamps is different from that of T8 lamps. , the distance between the pins is smaller than that of the T8 lamp tube and cannot be installed on the T8 lamp holder. Therefore, if you want to use the T5 lamp tube, you must replace the lamp holder together. Not only the installation process is extremely troublesome, but also causes resource consumption. waste. Similarly, for those who use T5 lamp holders, if they want to use T8 lamp tubes due to their needs, they cannot directly install T8 lamp tubes on T5 lamp holders.
