1. Understanding LED lights

Before talking about how LED lights can save energy and money, we must first understand what LED lights are?

LED lights use semiconductor materials to emit light. Because of its small light-emitting area and low output energy, LED lights were not suitable for lighting purposes in the past.

However, after continuous research and development and improvement, the luminous area of LED lamps has expanded, and its efficiency is stronger than that of ordinary fluorescent lamps or fluorescent lamps, and can be used for lighting purposes.

The advantage of using LED lights is that they do not have electric heating filaments, nor do they have to pass through gas discharge. However, the disadvantage is that its price is relatively expensive, and the smaller the size of the light source, the higher the light intensity (ie brightness) on the projection area, so the glare of the LED lamp is also relatively strong.

Second, the price is more expensive but more durable

Compared with ordinary incandescent bulbs or tubes, LED lights are more energy-efficient and durable! According to calculations, LED lights can save up to 85% of electricity. Despite this, its illuminance is not inferior to ordinary electric lamps, such as 13-watt LED bulbs, which are equivalent to 100-watt ordinary incandescent lamps, and their lifespan is 15 times longer than ordinary incandescent lamps, that is, about 15 years.

LED lights are slightly more expensive than incandescent lights, but save more money in the long run because of their long life!

In order to encourage Chinese people to save energy and replace ordinary incandescent lamps with LED lamps, according to the website of the National Environment Agency, since 2012, the price of LED lamps has become more affordable than the price in 2009, and ordinary consumers can also afford them.

Third, the advantages of using LED lights

The use of LED lights not only saves energy and money, but also has the following characteristics:

1. The lamp tube can replace the fluorescent lamp, and the light bulb can replace the incandescent lamp, which saves electricity by more than 85%. It is very environmentally friendly and does not need to be replaced frequently.

2. The service life is more than 15 years, which saves the cost of frequent lamp replacement and maintenance. The semiconductor chip emits light, no filament, no glass bubble, not afraid of vibration, not easy to break, and the service life can reach 50,000 hours (the service life of ordinary incandescent lamps is only 1,000 hours, and the service life of ordinary energy-saving lamps is only 8,000 hours).

3. Does not contain mercury, lead and other harmful substances, no ultraviolet, infrared, etc. Green light source, soft light.

4. The heat energy generated by the LED lamp is lower than that of the lamp tube, which can reduce the indoor temperature.

5. There is no adverse effect of stroboscopic and no noise interference.

6. High efficiency and energy saving: Compared with the same brightness, 3W LED energy-saving lamps consume 1 kWh of electricity in 333 hours, while ordinary 60W incandescent lamps consume 1 kWh of electricity in 17 hours, and ordinary 5W energy-saving lamps consume 1 kWh of electricity in 200 hours.

7. Health: Healthy light contains less ultraviolet and infrared rays, and produces less radiation (ordinary light rays contain ultraviolet and infrared rays).

8. Green and environmental protection: It does not contain harmful elements such as mercury and xenon, which is conducive to recycling. Ordinary lamps contain elements such as mercury and lead.

9. Protection of eyesight: DC drive, no stroboscopic (ordinary lights are AC driven, which will inevitably produce stroboscopic).
