Analysis and Evaluation of LED Street Light Test and Its Application Countermeasures

Author: Wu Chunhai recent years, LED lights developed rapidly in some cities to promote, but more cities are still in a wait state, street management's attitude is very cautious. In addition to the overall lamp life, light decay and other indicators have no authoritative data, whether it can save energy is also a lot of different opinions. In order to obtain first-hand data, Shenzhen Lighting Environmental Management Center and Shenzhen Science and Technology and Information Bureau, Shenzhen Electronic Product Quality Testing Center jointly organized LED street light testing, a total of 51 companies signed up, 29 passed the initial review, 27 participated in the test (2 The home failed to provide sample withdrawal). The test began in March and is expected to end in July and announce the results.

This article consists of two parts. The first part is the analysis of the registration information of 51 enterprises. The second part is the road test method and the result. Since the test is not finished yet, the specific data cannot be announced temporarily, but Wu Chunhai, director of the planning and design office of Shenzhen Lighting Environmental Management Center, still A number of important data were selected and analyzed in depth.

The first part of 51 companies registration data analysis

Through the research on the enrollment materials (including business licenses, product testing reports, etc.) of 51 companies, Wu Chunhai, director of the Planning and Design Office of Shenzhen Lighting Environmental Management Center, conducted a detailed analysis of LED street lighting enterprises, testing institutions and technical indicators. Some excellent companies have made great progress, and some models of LED street lamps have energy-saving space compared with existing mainstream lighting such as high-pressure sodium lamps. It is preliminarily believed that the critical point of LED street lamp application has arrived, and on this basis, relevant countermeasures and suggestions are proposed.

I. Analysis of the situation of the company

(1) Geographical distribution

There are 51 enterprises registered, and 29 enterprises have passed the initial examination. The geographical distribution of the enterprises is shown in Table 1-1-1 and Table 1-1-2.

This reflects the fact that the current domestic LED street lamp industry is very regional, and large enterprises across regions have not yet appeared. In this test, although Shenzhen local enterprises enjoy the advantages of information and location, they can still reflect Shenzhen's leading position in the LED street lamp industry. As a result, we have some concerns about the LED streetlight industry. The rise of local protectionism in cities is more important than the technical level and product quality in product procurement. The company's R&D impulses and technological innovations will suffocate, and low-level repetitive investment is inevitable. At present, this situation is very serious in China!

(2) Establishment time, registered capital, capital type

Note: The information of the two companies is incomplete. The sample of the sample in Table 1-1-x (x=3-5) is 49.

It can be seen from Table 1-1-3 that although the development time of domestic LED street lamps is not long, the establishment time of enterprises is not concentrated in recent years, but is distributed. The shortest period of establishment was less than half a year, in January 2009; the longest was more than 17 years, in December 1991. Obviously, enterprises mainly come through transformation. There are some traditional lighting companies, but the number is limited, and more are the original electronics manufacturers. At the same time, there are not many enterprises that mainly focus on LED street lamps. More enterprises only regard LED street lamps as a possible development direction, paving the way for future development, and do not rule out that some enterprises blindly enter the market enthusiasm.

From Tables 1-1-4 and 1-1-5, LED street light enterprises are mainly small and medium-sized domestic enterprises, with a registered capital of at least 100,000 yuan, but there are also many large enterprises with a registered capital of up to 2.3 billion yuan. Considering the mixed business of various companies, LED street lights are only a part of them, and the proportion is difficult to determine. Therefore, the amount of registered capital does not represent the strength of the company in LED street lights. From the point of view of market promotion, in order to improve user confidence, certain registered capital is also necessary. We think that more than 10 million yuan is more suitable, and the capital type has little relationship, but listed companies will have certain advantages.
