I. Introduction
Looking at the LED lighting market in recent years, the domestic related industrial chain and industry scale have taken initial shape, but most of them focus on the development of LED itself, materials, process and integrated lighting products, as well as lighting applications for pilot and demonstration projects. While LED lighting products continue to expand the scope of application and gradually move toward maturity of the product, more aspects and pre-opening links need to be considered in advance, especially affecting the product interchangeability and compatibility of enterprises and industries.
At present, the focus of concern is still: cost performance, high light efficiency, high power heat dissipation, light decay, optical design and light distribution, power supply and control, standard establishment, etc., although there are still bottlenecks, technical improvements and breakthroughs can be period. When such discussions are in the ascendant, when LED longevity and power saving are constantly being emphasized, should our manufacturers take long-term axis to think about the long-term development of enterprises? Should we also seriously face the end user's use, maintenance and long-term ultimate benefit protection [1]?
Environmental protection should not only focus on energy conservation and emission reduction! Our industry should seriously think about it: When long-life LED products end up in the end, if there are derivative faults, scraps and slow-moving products during this period, how many finished products and materials will become “garbage generated from the technological products†(garbage generated from the technological products) ) and difficult to handle! These are relatively lacking in care about the hot topics mentioned above, and the voices of potential victims may seem weak in the future and are not taken seriously.
Nowadays, domestic and foreign manufacturers have launched a variety of LED lighting products, most of which are not interchangeable and their performances are incompatible. Taking road lighting as an example, traditional light sources and lamps have already been standardized. Light source and electrical specifications have been formed into standard product series, and each product is interchangeable, which provides convenience for users to replace and maintain daily. In contrast, LED lamps, products are chaotic, lacking a complete series, products between suppliers are not interchangeable, resulting in limited application and subsequent maintenance work. In addition, due to the rapid replacement of LED technology, whether the performance of spare parts and new products can ensure compatibility, it is still necessary to observe or require manufacturers to provide corresponding supporting services.
There are many types of LED lighting products. Lighting manufacturers rely on their own development to occupy the market. From the market perspective, it can be foreseen: the market will be divided into segments. Suppliers of related components are faced with such diversified specifications, which is easy to cause instability in quality and productivity. It is difficult to effectively match supply speed and price, which will have a negative impact on the supply of lighting fixture manufacturers. Over time, the standard products (including components) within the company and suppliers cannot be fixed, the common parts are naturally insufficient, the quality is stable, the production capacity is increased, and the price and supply speed are also limited, which cannot meet the market competition and development needs.
Therefore, “interchangeabilityâ€, “compatibility†and “commonity†are the key links for the development and market acceptance of lighting products. If they are not able to be shared and effective by LED lighting manufacturers and owners (end users and maintainers) The convergence, the wide-ranging, large-scale project application, the steady improvement of supply chain capacity and the bigger and stronger enterprises and domestic industries will be directly affected by the impact.
Since the beginning of the year, many experts, scholars and manufacturers have proposed that modular lighting will be an important development trend of LED street lighting products. The street lights composed of light engines are springing up. The author has long been concerned about the development of LED lighting products and enterprises. I feel that the current situation of the LED lighting industry is a mess, leading to chaotic market order and constant questioning by the owners. It collects and aggregates product materials, reports and literature, and continuously communicates with local governments, owners and installation and maintenance units. Here, based on years of accumulated work experience, the basic design concepts, definitions, objectives, benefits, methods and successful experiences related to modular products are shared, from the perspective of end users, enterprises and lighting industry chain development. The problem, throwing bricks and jade to think about the future, the period to gather ideas and find solutions and ways out. This article is divided into three parts, mainly returning to the basic definition (back to basics), hoping to demonstrate the modular design and product architecture methods through the successful experience of the IT industry, and emphasize the effectiveness and continuous verification of LED light engine or modular design. The importance of designing innovative breakthroughs.
Second, the basic definition of LED lamps and light engines
At present, the industry group that manufactures LEDs is still insufficiently aware of the basic knowledge and requirements of lighting appliances, and the traditional lighting fixture production group often lacks extensive and in-depth understanding of the LED characteristics of lighting, and is not fully adequate in design and application. By using the characteristics of LEDs, the use of LEDs to avoid weaknesses and effective use, so when lighting LEDs applied to lighting devices, caused a lot of unreasonable or even wrong design [2]. To this end, it is necessary to link the two phases from the basic definition. This paper extracts the reference document [3][4] as the basis for the discussion:
Definition of lamps, lamps and LED modules:
- lamp: A light source made to produce optical radiation (usually visible). (Note: This term is sometimes used also for certain types of illuminators)
– LED array or module: LED package (component) or chip component on a printed circuit board or substrate, possibly with optical components, additional thermal, mechanical and intended connection to the load side of the LED driver Electrical Interface. The unit does not contain a power supply and a standard base. The device cannot be directly connected to the branch circuit, as shown in Figure 1.
