the difference of LED light
Ordinary fluorescent lamp
There is a filament at both ends of the fluorescent lamp. The tube is filled with traces of argon and thin mercury vapor. The inner wall of the tube is coated with fluorescent powder. When the gas between the two filaments is conductive, it emits ultraviolet rays, making the fluorescent powder emit soft Visible light.
Fluorescent lamp work characteristics: when the lamp tube starts to ignite, a high voltage is required, and only a small current is allowed to pass when it is normally illuminated. At this time, the voltage across the lamp tube is lower than the power supply voltage.
LED fluorescent lamp
Led fluorescent lamps are characterized by high quality, durability, and energy saving, with a large projection angle adjustment range, and the brightness of 15W is equivalent to that of ordinary 40W fluorescent lamps. High temperature resistance, moisture proof, waterproof, and leakage proof. The operating voltage is: 110V, 220V optional, and the outer cover can be made of glass or PC. The lamp holder is the same as an ordinary fluorescent lamp.
LED fluorescent lamp adopts the latest LED light source technology, digital appearance design, energy saving up to 70%, 12W LED fluorescent light intensity is equivalent to 40W fluorescent tube (used for ballast and starter, 36W fluorescent lamp real consumption The power is 42W to 44W). The life of LED fluorescent lamps is more than 10 times that of ordinary lamps, almost maintenance-free, without frequent replacement of lamps, ballasts and starters. The green and environmentally friendly semiconductor electric light source, with soft light and pure spectrum, is beneficial to the user's vision protection and physical health. The 6000K cold light source gives people a visually cool feeling, and the humanized illuminance difference design helps to concentrate and improve efficiency.
Compared with ordinary fluorescent lamps, LED fluorescent lamps have the following advantages:
1. Energy saving. 2. Long life LED lights. 3. Good applicability. Because of the small size of a single LED, it can be made into any shape. 4. The response time is short, which is ns (nanosecond) level of response time, while ordinary lamps have ms (millisecond) level of response time. 5. Environmental protection, no harmful metals, and easy recycling of waste. 6. The color is gorgeous, the light-emitting color is pure, the spectrum range is narrow, and can be mixed into colorful or white light through the three primary colors of red, green and blue.
Disadvantages: 1, expensive. 2. There is still a big gap between the light efficiency that can be universally achieved and the theoretical light efficiency. 3. There is still a big gap between the life span that can be achieved and the theoretical life span (10w hours). 4. There is still a certain amount of heat. 5. The light attenuation can be greatly reduced.
However, these shortcomings can be overcome through technological improvement, so even if the LED light source cannot completely replace the existing traditional light source, with the development of technology, it will definitely be the world of LED in the future.
