Fujian issued the country's first local standard for LED lamps

The local standard certification for LED lamps will be proposed: “The service life of LED lamps should not be less than 10,000 hours.” The standard has been revised and revised by experts and technicians from the Provincial Quality Supervision Bureau, the Provincial Center Inspection Institute, Fuzhou University and LED lighting companies. It was reported to the Provincial Quality Supervision Bureau for filing and will be implemented from May. It is reported that the standard will become the first local standard for LED lamps nationwide.
In recent years, LED lighting products have developed rapidly, but the relevant standards are still blank, and countries and regions around the world are stepping up development. At present, there are dozens of enterprises producing LED lamps in Fujian Province, which is one of the provinces with rapid development of such products in China.
LED luminaire products have a long service life, which can reach 10,000 to 20,000 hours, while the average life-saving lamp life is six or seven thousand hours, and the daily life of incandescent lamps is two or three thousand hours. These products also have good energy-saving effects, saving energy 4 to 5 times more than incandescent lamps. At present, LED lighting products are widely used in traffic lights, meters and displays.

Bi Directions Thyristor (Triac)

Bi Directions Thyristor (Triac) is equivalent to the antiparallel connection of two unidirectional thyristors, but only one control pole.
Bidirectional thyristors are made of N-P-N-P-N five-layer semiconductor materials, and three electrodes are also derived from the outside. Its structure is shown in the figure. Bi-directional thyristor volt-ampere characteristic curve Since the forward and reverse characteristics of the bidirectional thyristor are symmetrical, it can be turned on in any direction and is an ideal AC switching device.
