1). Explanation of misunderstanding
There is a misunderstanding in society that LED displays must be high-energy-consuming products due to their high brightness and large-area display characteristics, which are not conducive to environmental protection.
This concept may be due to a lack of understanding of the characteristics of LED technology and its energy efficiency.
2). The truth
2.1). The energy-saving principle of LED (light-emitting diode) technology:
- Low operating voltage:
LED is a semiconductor device that can directly convert electrical energy into light energy.
Its operating voltage is much lower than that of traditional lighting equipment such as incandescent lamps or fluorescent lamps, which means that at the same brightness, LED consumes less electrical energy.
- High luminous efficiency:
The luminous efficiency (i.e., luminous efficiency) of LED is much higher than that of traditional light sources.
The luminous efficiency of modern LED display screens has reached or exceeded 100 lumens/watt, which means that LED consumes less electrical energy when producing the same luminous flux.
- 可调节的 亮度:
LED display screens usually have a brightness adjustment function, which can adjust the brightness according to ambient light or actual needs, further saving energy.
For example, at night or in a dimly lit indoor environment, the brightness of the LED display screen can be appropriately reduced to reduce energy consumption.
2.2). Data support
According to multiple studies and actual application cases, LED display screens perform well in terms of energy consumption. For example, compared with traditional projection technology, LED display screens can reduce energy consumption by 30%-50% at the same brightness.
Compared with traditional flat panel display technologies such as LCD (liquid crystal display) and PDP (plasma display), the energy consumption advantage of LED display screens is more obvious, especially in large-size and high-resolution application scenarios.
3). Environmental advantages of LED display screens
Recyclability: The main materials of LED display screens include LED chips, circuit boards, shells, etc., most of which have good recyclability. With the improvement of environmental awareness and the advancement of recycling technology, the disposal of LED display screens will be more environmentally friendly and sustainable.
