LEDs have long-term, energy-saving, colorful, safe, and environmentally friendly features. The governments of Japan, the United States, the European Union, South Korea, Taiwan, and China have developed corresponding plans. It is therefore known as the third revolution in human lighting.
The benefits of LED lighting are unquestionable. LEDs require only 20% of the power of traditional incandescent bulbs. In the case of about 20% of the world's electricity used for lighting, switching to LED lighting will bring considerable energy savings. Benefits and reductions in greenhouse gas emissions, and countries around the world are arguing over how to price carbon dioxide pollution.
However, LEDs account for less than 10% of the lighting. To truly say the third revolution in human lighting, Imagine that LEDs have to be improved in terms of photoelectric efficiency conversion, heat dissipation, and price. The common people generally do not agree with LED, let's look at the LEDs in the eyes of ordinary people.
LED cost is too high
The high cost of LEDs is the biggest obstacle to the market's aggressive adoption of LED lighting. Industry experts pointed out that if the LED lighting market is to take off, the price of high-quality LED bulbs must be reduced to less than $10. The current price of LED bulbs is several times more expensive than $10. Investors strongly expect that as LED grass-roots companies reach economies of scale and technology continues to advance, costs will fall rapidly.
Although the cost of the LED light source is decreasing year by year, the cost of the LED light source combined with the heat dissipation structure and the driving power source is also very considerable, and the reason is the material price factor, and a large part is the input of the processing link. In addition, various manufacturers have launched their own design of lighting fixtures, which has also caused a significant increase in the cost of molds, processing fees and so on.
LED performance is unstable
A civil organization was refurbished, and the indoor lighting was replaced with LED lights sponsored by member companies. But soon I changed back to the energy-saving lamps. There is no way. I always have such problems. I have to ask people to repair them every month. It is very troublesome. If you don't save energy, you don't know. The cost of repairs is higher than the cost of using energy-saving lamps. At this stage, LEDs entering home lighting will face developmental bottlenecks such as performance uncertainty. For example, LED heat dissipation is a big problem. The most terrible thing is that LEDs are directional. If you look directly at the naked eye, it will feel very dazzling and will not last long. The eyeball is very easy to fatigue.
At present, the proportion of LED lamps used in the LED market is very small. Mercury gas street lamps will be replaced by LED lamps due to environmental pollution. At present, mercury gas lamps account for 30% of the market share of LED street lamps, and the proportion of street lamps in lighting lamps in various countries around the world. Between 15% and 40%. In the next 3-5 years, LED street lamps will account for the global LED market share from 1% in 2007 to around 7% in 2011.
