I. Introduction
Looking at the LED lighting market in recent years, the domestic related industry scale and industrial chain 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-requisite links need to be considered in advance, especially those products that affect the development of enterprises and industries to be "interchangeable" and "compatible". Sex."
At present, the focus of concern is still: cost-effective, high-efficiency, high-power heat dissipation, light decay, optical design and light distribution, power supply and control, standard establishment, flaws, etc., although there are still bottlenecks, but technical improvements and breakthroughs can be period. When such discussions are in the ascendant, when LED longevity and power saving are constantly emphasized, should our manufacturers take long-term axis to think about the long-term development of enterprises? Should we also seriously face the use, maintenance and long-term end-users of end users? Protection of interests [1]?
Environmental protection should not only focus on energy conservation and emission reduction! Our industry should seriously consider: When long-life LED products are finally dead, if there are derivative faults, scraps and slow-moving products, how many finished products and materials will become " "Technical waste" is difficult to handle! Compared with the hot topics mentioned above, these are really lacking in care. The voice of the victims may seem weak in the future and they 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 not compatible. 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 “universality†are the key links in the development and market acceptance of lighting products. If they cannot be jointly and effectively connected by LED lighting manufacturers and owners (end users and maintainers) Realization, 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.
Second, LED lamps and light engines
However, from the perspective of the introduction of domestic products, especially in the road and tunnel lighting, in addition to the annual integrated lighting, there have been many LED light engine combinations since 2008, but there is no LED light. Professional engine supplier. In general, the LED light engine combined with street light or tunnel light fixtures, still like most of the original integrated lighting, can not escape the "old bottled new wine" approach, failed to effectively target the new LED light source characteristics, avoid weaknesses, and failed to be effective Take advantage of the features and benefits of LED light engines and modular design [6].
In this way, it is bound to cause the market to be full of diversified products. When the manufacturers are independent, they are doing everything, even if the experts of the scholars and the market expect, but the basic problems of concern and questioning by the employer and the maintenance unit: "interchangeability" and "compatibility" , not seeing substantial resolution. Thus, as a result of diversification and diversification, although efforts can be made to expand the market, it may lead to a smaller market block, or it may be a small market.
Product development and promotion have its own process, but once again, people are worried: whether a large number of LED lighting manufacturers can distinguish the shortcomings of integrated LED street lighting from the perspective of the product itself, the enterprise itself, the end user and the industrial supply chain. What is the difference between the LED light engine and the street light fixture? What is the product that is widely accepted in the market?
Looking at the development of industries and products at home and abroad, products with modular design have become mainstream in many markets. Among them, the success and popularity of personal computers (PCs) are the most popular. Nearly all PC products are based on the standardization of related components. Modularization. At the same time, modular product design has also been successfully applied in: printers, notebook computers, cameras, mobile phones, electric hand tools, machine tools, autos, aircraft, sputum and other industries, and successfully developed a series of products. Not only the product features continue to improve and the market expands rapidly, but at the same time it brings to the masses of consumers: the satisfaction of functional requirements and the convenience of life.
In short, interchangeability, compatibility, versatility, and sustainability are the basic goals and spirit of modular design products that create significant benefits for markets, businesses, and industries. In addition, global product sharing product platforms The concept is also widely used in these industries. The modularization, standardization, and technical application of the product platform not only achieve the key reasons for rapid development, quality improvement, customized design and cost reduction, but also become the industry's concurrent engineering and collaborative design. Important practice means [7]~[10].
In view of the fact that LED lighting products, technologies and enterprise development need to integrate various professional fields and experiences highly effectively, it is necessary to have a basic definition of modularization to successful examples of product design, from product design concepts and modular features to benefit verification, from enterprise to industrial value. The value chain learns and borrows the experience of the mirror, and then can be carried forward according to the LED characteristics and lighting products.
