Problems in the application of LED street lamp (Part 1)

Under the situation of global energy crisis and environmental pressure, the application of LED light source in road lighting has become a hot topic in recent years. LED device products applied to the street, what are the special requirements of the technology, and the traditional LED lamp high pressure sodium lamp compared with what advantage, what is insufficient, how to solve a series of problems that are worthy of our study.

Product standardization and versatility is the basis for large-scale use

At present, the introduction of LED street lamp, the appearance of the product, the arrangement of the LED luminous particles and the number, the size of the rectifier circuit and a variety of internal design. Such as: the single power quantity is different, 1~5 watt light distribution in different range; a bat shaped, rectangular, butterfly wing type; optical processing method has a built-in lens free two optical processing and two optical processing; a special drive chip IC and without electrolytic capacitor; a multi chip package and package single chip package technology; line mode, group type high power integrated chip, high power, high power and dot matrix. The power assembly also has built-in integration and external power supply two, cooling technology to the maintenance and each one has its own merits, the popularization of the operation is inconvenient, also do not accord with the standard of municipal utilities, general design principles of.

We believe that in the future development process, manufacturers should be strictly in accordance with national standards, to ensure the safety and reliability of the product in terms of equipment safety. At the same time, the application of LED products in the field of urban lighting, the product must be standard, unified to provide the following guarantees.

Such as: for the different stages of development of the same enterprise products, to ensure the standard of the main electrical components of the unity, to avoid the product renewal caused by spare parts for dating; between the products of different enterprises, the lamp body, luminous particle board, rectifying circuit of main electrical components according to national standards, implementation of standards necessary, unity.

The corresponding national standard is the guarantee of the healthy development of LED street lamp Market

The photoelectric and thermal characteristics of LED are very different from the traditional light source, so that the existing LED measurement can not be fully applied to the measurement method of the traditional lighting source. At present, no matter in the product specification or measurement of LED are lack of appropriate standards, so that a wide range of products, measurement is not standard, the market is not standardized, and the diversity of products also led to the enterprise can not focus on mass production. The development of relevant LED standards has become an urgent need for the industry. At present, by the National Standardization Technical Committee "lighting the general lighting LED national standards and industry standards" in the trial stage, is expected to be promulgated and implemented. Related enterprises should carry out new market positioning and product planning, seize new opportunities, put the necessary means of quality assurance.
