The significance of LED is not only energy saving, but more importantly, the revolution that causes lighting.
Don't say that LEDs are energy efficient. Really, because this is not fair to LEDs.
We usually divide the light source technology into three generations: the first generation of heat radiation source, the second generation of gas discharge source, and the third generation of solid state light source, which is LED.
The first generation: heat radiation source
Second generation: gas discharge light source
Third generation: LED light source
From incandescent lamps to CFLs, there is no doubt that there is significant energy savings.
But now we can say that LEDs are several times more energy efficient than fluorescent lamps than metal halide lamps? It seems that no one dares to say this, as if selling LEDs is still more energy-consuming than halogen lamps. Even so, even if it is not energy efficient, LEDs are still revolutionary.
The simplest, and probably the earliest, and now the biggest cabbage in the LED luminaire is the LED strip. We take the product parameters of a Japanese brand as an example (Taobao explosions, highlights, super bright, super bright, 5 yuan, one meter, one meter, one meter, one thing, we don’t care anymore), 10W LED strips per meter, light effect About 60lm/w, this is not comparable to straight tube fluorescent lamps. However, after being associated with the application scenario, it is obvious that the current hotel ceiling light trough will not be equipped with straight tube fluorescent lamps or cold cathode tubes, all of which are LED lights.
Probably no one would say this: "Hey, your LED light has no luminous efficiency, no fluorescent light, not enough energy, so I don't buy it." Because the LED is a directional 120° light, in this scenario, we It will be found that a part of the so-called high-efficiency light of the 360° light of the straight tube fluorescent lamp is actually wasted, and the final LED strip can replace the straight tube fluorescent lamp with a lower power and less energy-saving light effect number.
