At present, there are many LED street lights in urban road lighting, but there are still many difficulties in the promotion of LED street lights. At the same time, there are huge business opportunities. In response to these situations, Professor Ye Rongnan of Xiamen Photonics Industry Association has conducted in-depth research. Analysis and discussion.
First, the status of LED street lighting industry
1. Large enterprises wait and see, test water, and launch conceptual lamps from time to time, but do not want to wading too deeply;
2. Most small enterprises adopt adopting or plagiarizing other people's products due to restrictions on capital and technology;
3. The owner applies the concept of gas discharge lamp, thinking that as long as a certain power LED is placed in the lamp holder, it can meet certain road lighting requirements;
4. There are also a small number of small enterprises that regard LED street lamps as their main business, strengthen their investment in science and technology, form their own intellectual property rights, and obtain patents, which have contributed to the development of LED street lamps.
Second, the difficulty of promoting LED street lights
1. There are no street lamp technical specifications covering LED characteristics;
2. The mindset of the professional department is difficult to reverse at one time;
3. The policy failed to cooperate in time;
4, LED street lamp cost is too high, one-time investment is too large;
5, people have a process of understanding LED, it takes some time;
6. Some experts are not optimistic about the use of LED street lights for the main roads. They think it is too early to publish articles in various forums and publications, which has a great impact.
Third, the anxiety of experts
1. The luminous efficiency of practical LEDs is much lower than that of high pressure sodium lamps;
2. The street lighting uniformity of LED street lights is poor. The zebra crossing is serious;
3, LED heat is difficult to solve, the heat is too strong, the light decay is serious, the life is not reliable.
4, LED color temperature is too high, glare; and high pressure sodium lamp color temperature is low, comfortable, strong ability to wear fog.
Therefore, some experts suggest that LED street lights are only suitable for secondary roads with poles below 8 meters. The main road should use high-pressure sodium lamps with low color temperature.
Fourth, business opportunities
In fact, there are huge business opportunities in this piece of opposition:
1. Cost-effectiveness: LED's luminous efficiency is improved very quickly. Taking CREE as an example, LED lights of >100lm/W are now available. At the same time, the price of the lamp has dropped from 37 yuan/80lm last year to 24/100lm ( With tax), this trend has not changed.
2, the green trend: the world's energy-saving, environmental protection, green trend in China, in the lighting industry is still surging, LED street lights will be widely used in urban road lighting, this is a consensus.
3. Timing and Kung Fu: The above doubts are not insurmountable. As long as the research on secondary light distribution and heat dissipation is strengthened, the current LED light efficiency level can design LED street lights that fully comply with the current road lighting standards, and can be done more. it is good. The key is to work hard, not opportunistic.
4. Opportunities: In the situation of watching and seeing everywhere, we will provide opportunities for us. Those who are interested can seize the highland of high-end products of LED street lamps.
5. Financial support: In some industries, under the premise of sluggishness, some industry players have changed jobs; instead, they have provided more abundant financial support to the LED industry.
