普通日光燈與LED日光燈的區別

Ordinary daylight lamp
Both ends of the fluorescent lamp is a lamp filament, filled with argon and rare trace mercury vapor, the inner wall of the tube is coated with fluorescent powder, ultraviolet radiation gas between the two conductive filament, the phosphors emit soft visible light.
Fluorescent lamp work characteristic: when the lamp tube starts to ignite, needs a high voltage, when the normal illumination, only allows to pass the very little current, then the lamp tube two end voltage is lower than the supply voltage.
LED fluorescent lamp
LED fluorescent lamp is characterized by high quality, durability and energy saving. Its projection angle is wide, and the brightness of 15W is equivalent to that of ordinary 40W fluorescent lamp. High temperature resistant, moisture-proof, waterproof, anti leakage. Use voltage: 110V, 220V optional, cover optional glass or PC material. The lamp holder is the same as the ordinary fluorescent lamp.
LED fluorescent light using the latest LED technology, digital design, saving more than 70%, fluorescent lamp fluorescent light intensity LED 12W is equivalent to 40W (for ballast and starter, power consumption of fluorescent lamp 36W true 42W to 44W). LED fluorescent lamp life is 10 times more than ordinary tube, almost free of maintenance, do not often replace the lamp tube, ballast, starter. Green semiconductor light source, soft light, pure spectrum, is conducive to the user's visual protection and health. 6000K's cold light source gives people a visual and cool feeling, and humanized illumination difference design is more helpful for concentrating and improving efficiency.
LED fluorescent lamp and ordinary fluorescent lamp contrast, the advantages are as follows:
1, energy saving. 2, life LED lamp length. 3, the applicability is good, because a single LED is small in size and can be made into any shape. 4, the response time is short, the NS (nanosecond) level of response time, while the ordinary luminaire is the MS (millisecond) level of response time. 5, environmental protection, no harmful metals, waste easily recycled. 6, brilliant color, light color pure, narrow spectral range, and through the red green and blue three primary colors mixed into colorful color or white.
Disadvantages: 1, the price is expensive. 2, there is still a big gap between luminous efficiency and theoretical light efficiency. 3, there is still a big gap between the length of life and the theoretical life (10W hours). 4, there is still a certain amount of fever. 5, can greatly reduce the light attenuation.
However, these shortcomings can be overcome by the improvement of technology, so even if the LED light source can not completely replace the traditional light source, but with the development of technology, some days after the LED the world.
Applications in advertising
Advertising applications are mainly based on large characters. Mostly insert small light source for big characters, increase the display effect.
