Ordinary fluorescent lamp
There is a filament at both ends of the fluorescent lamp. The tube is filled with a small amount of argon and thin mercury vapor. The inner wall of the tube is coated with phosphor. When the gas between the two filaments conducts electricity, it emits ultraviolet light, so that the phosphor emits soft visible light.
Working characteristics of fluorescent lamp: when the lamp tube starts to ignite, a high voltage is required, and only a small current is allowed to pass during normal lighting. At this time, the voltage at both ends of the lamp tube is lower than the power supply voltage.
LED fluorescent lamp
LED fluorescent lamp is characterized by high quality, durability and energy saving. It has a wide range of projection angle adjustment. The brightness of 15W is equivalent to that of ordinary 40W fluorescent lamp. High temperature resistance, moisture-proof, waterproof and anti electric leakage. Operating voltage: 110V, 220V, glass or PC material for enclosure. Lamp cap is the same as ordinary fluorescent lamp.
LED fluorescent lamp adopts the latest LED light source technology and digital appearance design, which can save more than 70 percent of electricity. 12W LED fluorescent lamp is equivalent to 40W fluorescent tube (used for ballast and starter, and the real power consumption of 36W fluorescent lamp is 42W to 44W). The service life of LED fluorescent lamp is more than 10 times that of ordinary lamp tube, which is almost maintenance free, and it is unnecessary to replace the lamp tube, ballast and starter frequently. The environment-friendly semiconductor electric light source, with soft light and pure spectrum, is conducive to the vision protection and health of users. The 6000K cold light source gives people a sense of visual coolness. The humanized illumination difference design is more conducive to concentration and efficiency.
