The difference between LED light source and ordinary light source What is the difference between LED energy-saving light bulbs and ordinary light bulbs
We all know the impact of light on the eyes, a good The light source of the light source is very good for the eyes. Take the incandescent lamp that we often use for example. You may think that if I buy a higher power one, it will be brighter, but the light color of the incandescent lamp is yellowish. Working under such light for a long time is very tired and the impact on the eyes can be imagined.
LEDLight source technical features
here Let me tell you that the best light source is the LED light source. If you still use this LED desk lamp to read and write homework, you will find that your eyes are not easy to get tired. This technology has the following characteristics:
1. The use of low-voltage power supply is not like traditional light bulbs that use 220v direct power supply, which ensures that safety. Especially if the lamp used by children is ordinary 220v voltage, it is not very safe.
2. It is more technical, and its unique light-emitting principle makes LED lamps sell very well, and the energy consumption is about 20% of the incandescent lamps with the same luminous efficiency.
3. Applicability: LEDs can be made into individual small units, so they can be prepared into components of various shapes and have strong adaptability to the environment.
4. Stable to long running time: According to the official introduction, even if it is used for 100,000 hours, the attenuation of light is only about 50%.
5. Short lighting response time: Here is a metaphor for “if the response time of ordinary incandescent lamps is one year, the response time of LED lamps is only one hour.

6. Environmental protection: the content of harmful metal mercury is close to zero.
7. If you want to change the color of the light, you only need to adjust the voltage. As troublesome as ordinary lamps.
Characteristics of energy-saving lamps
1. The service life is up to 8000 hours, and the light efficiency is 6 times that of ordinary bulbs.
2. Compared with ordinary fluorescent lamps, it can save energy by 70-80 %, low voltage and quick start, no stroboscopic.
3. Using pure three-color phosphor tube, the lighting object is bright and fresh.
4. The appearance design is novel, the bracket is made of aluminum alloy material, small and beautiful, never rust, flame retardant.
The promotion significance of energy-saving lamps
The promotion of energy-saving lamps is of great significance. However, the harm of waste energy-saving lamps to the environment also causes The mercury content of an ordinary energy-saving lamp is about 5 mg, which is only enough to cover the tip of a ballpoint pen, but it may cause 180 tons of water pollution after infiltration into the ground. Due to the low boiling point of mercury, it can be evaporated at room temperature, and discarded After the energy-saving lamp is broken, the mercury concentration in the surrounding air can be exceeded by hundreds of times in an instant. Once the mercury enters the human body exceeding the standard, it will damage the central nervous system of the human body, and the human body can be killed by inhaling 25 mg of mercury vapor at a time.
China’s energy-saving lamp promotion strategy has a long history. In 2008 alone, 62 million energy-saving lamps were promoted nationwide, and by 2009, it was as high as 1.2 billion. The national promotion of energy-saving lamps reached as high as 200 million. China is still blank in terms of the harmless treatment of energy-saving lamps. Broken energy-saving lamps are sent to landfills with domestic waste. In 2006, the number of mercury-containing lighting appliances that were scrapped in China was equivalent to 40 watts of standard fluorescent lamps. The amount of mercury released into the atmosphere due to improper disposal reaches 70-80 tons. The disposal and recycling of waste energy-saving lamps has attracted attention.
LED energy savingCharacteristics of lamps
1. The energy consumption of white LEDs is only 1/10 of that of incandescent lamps. 1/4.
2. The service life can reach more than 50,000 hours, which can be described as “once and for all” for ordinary household lighting
3. Yes Work at high speed. If the energy-saving lamp is frequently started or turned off, the filament will turn black and quickly break down.
4. Solid-state packaging, which belongs to the type of cold light source. Therefore, it is very convenient to transport and install, and can be installed in any miniature and closed equipment. It is not afraid of vibration and basically does not need to consider heat dissipation.
5. Environmental protection, no harmful substances such as mercury. The assembled parts of the LED light can be easily disassembled and assembled, and can be recycled by others without being recycled by the manufacturer.
6. LED technology is progressing rapidly, its luminous efficiency is making an amazing breakthrough, and the price is also decreasing. An era of white LEDs entering the home is rapidly approaching.
LEDDisadvantages of energy-saving lamps
1. The efficiency of LED energy-saving lighting is still not high. Today’s LED energy-saving lighting efficiency is generally 60-70lm/W. As a new generation of light sources, LED energy-saving lighting If the efficiency can reach 120lm/W, then it will be the spring of LED lamps.
2. LED energy-saving lamps need corresponding heat sinks. If the heat generation of the LED chip itself is not greatly improved, the structure of the heat sink and the application of heat pipe technology are required. ,further development.
3. LED energy-saving lamps, the price is too high, LED single price, aluminum radiator, high-efficiency constant current power supply, high light transmittance and soft lampshade, the cost of the four is collectively pushed up LED cost.
4. The color rendering index is not high. Most of the LED energy-saving lamps have a color rendering index of less than 80. Compared with energy-saving lamps, there is still a gap.
Therefore, LED energy-saving lamps can be used as downlights, spotlights, and chandeliers. However, if you want to replace ordinary energy-saving lamps with LED energy-saving lamps on a large scale, you still need LED energy-saving lamps themselves have overwhelming advantages.
Summary: At present, the country pays more and more attention to lighting energy saving and environmental protection issues, Vigorously promote the use of LED lights. Energy-saving lamps basically have to be replaced after one year of use, but the service life of LED lamps is much higher than that of energy-saving lamps. They can be used for more than ten years, which can save a lot of electricity bills. In the long run, LED lamps will save money. Another is , The metal mercury pollution of energy-saving lamps is very serious, which will have a serious impact on the living environment around them. LED lamps are energy-saving and environmentally friendly. And as long as the cost of LED lamps decreases with the continuous improvement of LED technology. Energy-saving lamps and incandescent lamps will inevitably be replaced by LED lamps.
