The secret of lighting longevity

The so-called lighting, as the name implies, is a lamp without electrodes. The main advantage of this lamp is that it eliminates the key factor that restricts the life of traditional lamp sources-electrodes. In an ordinary lamp source, with the ignition of the lamp, the electron emission material on the filament will continue to be consumed, and the electron emission ability of the electrode will gradually decrease as a result. At the same time, some electrode materials will also sputter on the inner wall of the tube. This caused difficulty in starting the lamp in the later stage of ignition, and the luminous output also dropped greatly. Moreover, the electrons emitted by the electrodes under the working voltage are not enough to sustain the discharge, and the lamp will be extinguished. On the other hand, lighting decorations, due to the elimination of the electrode factor, the life of the lamp can be greatly improved, and the maintenance of the luminous flux of the lamp is much better than that of the traditional lamp source. In the near future, with the development and progress of electronic technology, there will be more high-quality and low-cost components suitable for lighting and electronic circuits with special functions. Therefore, we have reason to expect that lighting will replace traditional light sources and become the first choice for lighting sources. The commercial production of lighting can be traced back to 1991, when Panasonic Corporation of Japan launched a lighting in Japan, which uses the H-type discharge principle to work. An air core induction coil is wound around the equator of the blister, and a ballast is also built-in. Its operating frequency is 13.56 MHz. For a 27-watt lamp, its working voltage is AC 100V, and the corresponding luminous flux output is 1000 lumens. Therefore, the luminous efficiency is 37.0 lumens/watt. And its average life span is as high as 40,000 hours. In order to prevent electromagnetic interference, this kind of lamp is also covered with a metal cover. Almost at the same time, in 1991, the Dutch Philips company also launched a lighting, it is called 'QL lighting.' Its structure is that an excitation coil is wound on a rod-shaped iron core, the bulb of the lamp is airtight, and one end is recessed, and the iron core wound with the coil can just be inserted into the recess on the bulb. At the same time, in order to solve the heat dissipation problem, a heat conduction pipe is arranged on the iron core. There are two amalgams, main and auxiliary amalgams in the bulb, the auxiliary amalgams are responsible for providing suitable mercury vapor pressure when the lamp is started, so that the lamp can achieve a relatively high luminous flux output in a short time; while the main amalgams function It is to keep the mercury vapor pressure in the bulb in the best range when the lamp is working. This lamp works at a frequency of 2.65 MHz. The luminous output of a 55-watt QL lamp can reach 3500 lumens (luminous efficiency is 63.5 lumens/watt); and the luminous output of 85 watts can reach 6000 lumens. (The luminous efficiency is 70.6 lumens/watt); the life of the lamp is as high as 60,000 hours. The lighting factory is an energy-saving service company engaged in lighting research and development, production and sales earlier in China. While introducing advanced foreign technology, the lighting factory has reformed and innovated to form its own leading products. The lighting factory is the first domestic manufacturer with independent research and development, independent production, and independent intellectual property rights.
