What is the difference between a led light and a fluorescent light?

Guide: Since Edison invented the light bulb, human life has since entered the light. Nowadays people are leaving the lights of the lights. It is completely inconvenient. It is dark in the night. At night, the neon is flashing. We start our night life in a bright environment. The development of light bulbs has also ranged from simple tungsten filament bulbs to various types of bulbs. Led light is one of the most common light bulbs used nowadays. What is the difference between led light and fluorescent light? When it comes to protecting eye fluorescent light and led light, these eye protection are good. These are the things we need to understand. Let's follow the small series to learn about LED. What is the difference between a lamp and a fluorescent lamp?

What is the difference between led and fluorescent lamps?

What is the difference between a led lamp and a fluorescent lamp? First, an ordinary lamp is a fluorescent lamp, and the principle of illumination is different from that of an LED lamp. Fluorescent lamp illumination is the high voltage generated when the ballast is energized, which stimulates the discharge between the two pins inside the lamp tube, and then excites the phosphor to emit light. This process produces high heat. LED luminescence is the electron migration inside the semiconductor, the luminescence generated, and the luminescence process does not generate heat. This is why LEDs are called cold light sources.

What is the difference between led and fluorescent lamps, and secondly, LED lamps have high luminous efficiency and high brightness. Now the good LED fluorescent tube on the market can achieve more than 130 light effects, which is about twice that of fluorescent lighting. In other words, the 18W LED fluorescent lamp can be used as a 36W fluorescent lamp. From the actual lighting effect, the 130W/W 18W LED lamp can be used as a 48W fluorescent lamp.

What is the difference between led and fluorescent lamps, again, LED lamps have a long service life. The life of the LED can reach more than 50,000 hours (excluding the power supply), and the life of the fluorescent tube (excluding the power supply) is 10,000-20000 hours.

Fluorescent and led lights are good for eye protection.

Fluorescent lamps and led lights are good for eye protection. Now they are all pretending to have no stroboscopic LEDs. In fact, this is not the case. LED lamps have many control modes, and there is a resistance to buck, and then rectification plus a capacitor filter, so that the actual DC There is a strobe of 100Hz. Some use high-voltage constant current sources, this frequency is in the tens of KHz, and generally does not feel stroboscopic. There is also a PWM dimming LED lamp, which has a pulse-adjusted on-time of a few KHZ to adjust the LED brightness. Fluorescent lamps are typically 50Hz stroboscopic (rectifier type), and electronic rectifiers have tens of kilowatts stroboscopic.

From a personal point of view, the LED light is a bit dazzling and not as soft as a fluorescent light. If it is not necessary now, it is recommended not to buy LED lighting series. 1, the price is high. 2, the technology is not mature enough (especially the power supply part).
