High-power white LED lighting products have been in the urban and rural road lighting application market for more than 6 years. With the globalization of “energy saving, low carbon economy” and the support of our national policies, each Local government departments attach great importance to the application of LED street lamps. The use of LED road lighting fixtures has more market opportunities, and more and more lighting manufacturers and optoelectronic products companies in China are also pushing various products. The market, for a time, road lighting around the country is not talking about LEDs, and the traffic is unusual.

However, with the application and application, there are very few projects in China that have achieved good results and expected economic benefits in terms of LED street lamps. It can be said that almost no user is satisfied with the actual application effect of the products, and there is no R&D and manufacturing. Manufacturers or lighting engineering companies have achieved good market performance and economic benefits in LED products, and local street lamp management departments have severely resisted the high maintenance costs caused by the blind promotion of mature LED street lamp products, making high-power LEDs There is no way for streetlights to truly form a healthy and healthy market. It is still a state of “satisfaction and not a seat”, and even severely hits the confidence of many enterprises and practitioners in the industry.

The reasons for the above phenomenon, in addition to the economic cost factor, the most important thing is that the overall quality and reliability of the product cause poor use, high maintenance and replacement costs, and even affect the engineering image, so that many have the economic ability and are willing to promote the use of new products. The customer, there is a feeling of being deceived, thus losing confidence in the LED road lighting products, from support to boycott, and finally give up. The reasons for the poor quality and reliability of the products are as follows:

1. Most LED street lamp manufacturers are not specialized in researching optoelectronic products but are extending from the traditional lighting industry. These two products have essential differences from performance to application, but the manufacturers do not master these rules and produce them. The products do not meet the characteristics of LED optoelectronic products, resulting in waste of resources and serious product damage;

2, the most fundamental problem affecting the life and damage rate of LED light source----heat dissipation and balance are not well solved, or the solution mechanically pay attention to structural heat dissipation, while ignoring many of the characteristics of LED itself;

3. The application of the optical characteristics of the LED light source is simple, which makes it difficult for the final street lamp product to meet the most basic illumination and uniformity requirements of the road lighting, which brings problems to the user and the street lamp management department;

4. Because there is no good heat dissipation and light distribution scheme, and there is no clear national or industry standard, the structure of the street lamp is very strange, but without exception, the outer casing needs to be mechanically dissipated in the form of large-area fins, resulting in self-cleaning of the street lamp. The ability does not meet the requirements. The accumulation of dust and guano grasses is more hindering heat dissipation, and the product is quickly damaged. The maintenance and use cost of the street lamp management department is greatly improved, and the long-term energy saving effect is counterproductive. In the process of building a new socialist countryside, the LED street lamps that were used in large quantities were extremely shocking due to lack of supervision and maintenance, and they also caused extremely bad effects on the construction of new rural areas.

In response to the above problems and the reasons for their formation, domestic leading technology professionals and manufacturers have been working hard to solve the fundamental problems and promote the healthy development of the industry. Jinyi Optoelectronics Technology (Shanghai) Co., Ltd. recently launched its domestic and international It is the only leading high-power LED street lamp and tunnel lamp product, which completely solves the above problems, and eliminates all the bad phenomena in the process of use. It is a true name for the real LED street lamp, and it has taken a brand new for the development of the market and products. path of.

Jinyi Optoelectronics Technology (Shanghai) Co., Ltd. integrates its 15 years of experience in the research and development of optoelectronic products, and adheres to the high-power LED road lighting fixtures manufactured by the process of “light, machine and electricity”. In response to several key defects of LED street lamps, they have taken corresponding measures to solve them fundamentally. They have used the research results obtained in the process, materials and structure for more than 10 years, and utilized more than 20 patent technologies obtained in China. A targeted solution was proposed, which is described as follows:

1. According to the experience and development of the LED light source characteristics in the past 15 years, the most basic chip customization and screening process will be carried out according to different application places and lighting requirements, emphasizing chip purity and consistency for product application. Lay a solid foundation;

2. The patented heat dissipation technology ensures rapid heat absorption from the package to the assembly process, and heat dissipation until the result of heat balance. The patented heat dissipation structure and unique thermal research materials (international patent products) are used throughout the process to make the LEDs The product finally achieves a true heat balance, fully complying with the characteristics of the LED illuminating heat, so that the product completely eliminates the hidden danger caused by heat and light decay until damage;

3. During the assembly of the LED light source until the assembly of the luminaire, multiple light distributions are used, and the illuminating characteristics are used to make the application products fully meet the functional requirements of road lighting, and the illuminance to uniformity can perfectly replace the traditional light source street lamps. Standard

4. The unique heat dissipation technology and light distribution technology enable the LED street light source part of Jinyi Optoelectronics to be combined with any traditional street lamp of any shape and structure in a modular form, ensuring that LED street lights will not lose self-cleaning ability due to their limitations. As well as the limitations of the installation, it is greatly welcomed by the streetlight use and management department, and it ensures that the urban road will not reduce the streetlight style due to the limitations of LED streetlight modeling.

Once the LED street light with the above performance characteristics was launched, it began the experimental installation project in the actual application site, and achieved good application results, and was further affirmed by the management departments such as street lamps. This emerging LED street lamp technology is indeed How to smoothly communicate with traditional street lamps, the technical improvement has played a good role. The following are two examples of practical applications:

Example 1. Tsinghua University campus road lighting

Venue: Installation time on Tsinghua University campus: August 20, 2008 Lighting power: 72W
Site conditions: Main roads on campus Pavement width approx. 10 m Pavement material Asphalt road Installation height 10 m Installation distance Interval 40 m, one-sided installation measured data: (after nearly 600 days of use)
Average vertical illumination 33.08 LUX
Average 5 meter radius illumination 24.68LUX
Average 10 meter radius illumination 3.06LUX
Average 20m radius illumination 0.36LUX

Lamp description: The lamp is a 72W high-power LED street lamp of the model GF6100c produced by Jinyi Optoelectronics Technology (Shanghai) Co., Ltd. The lamp structure is a single 1W light source module combination (see picture), which is carried out during the light source packaging process. The patented technology and process flow of the light distribution are reconstructed, so the actual application luminous flux can reach 100Lm/W.
