The current status of domestic LED lighting fixtures and the top ten applications

The LED lighting industry has indeed achieved rapid development in recent years, especially in the field of downstream applications, especially in Guangdong Province. However, after rapid development and growth, patents have increasingly become the bottleneck for the further development of LED companies. Therefore, it is not too late for the company's patent layout to be done at any time, where to do it, and what to do.

Simply put, the patent layout is the overall goal of the company's patent distribution in a certain period of time in the future, and further plans for each layout stage according to the development plan of the enterprise, and determines the patent layout tasks and measures at each stage; in each implementation stage, the patent of the enterprise Management also needs to provide more specific indicators on the number and structure of patents. In addition, in the implementation process, enterprises also need to investigate the layout plan in combination with the implementation of the patent layout plan, the adjustment of the enterprise development plan, and the changes in the external technology, industry and market environment.

First, let's take a look at the basics of LED lighting:

LED lighting fixtures are collectively referred to as LED lamps. They refer to appliances that can transmit, distribute, and change the light distribution of LED sources, including all the zeros, components, and power connections required to fix and protect LED light sources except LED sources. Required line attachments. Simply put, it is the LED light source, the heat sink, the lamp housing, the drive power supply, the support, and the necessary circuit aids and the means to connect them to the power supply. The lighting design of the 21st century room will be based on the design of LED lighting, and at the same time fully reflect the development trend of energy-saving, healthy, artistic and humanized lighting, and become the leading of the room lighting culture.

The problems currently plaguing LED lighting technology are as follows:

1. Domestic enterprises have no core technology

Most of the core patents in the upstream of the LED industry are in the hands of foreign companies. We don't have the core technology in China. Although our LED application products account for 50% of the global manufacturing capacity, the share accounts for 50%, but in the profit segment. It is the lowest part. The cost of LED lighting is mainly in the LED chip. As long as the price of the chip is lowered, the lumen price of the LED can be reduced to the equivalent of the current energy-saving lamp. Because the LED chip adopts a larger-sized wafer fabrication process with the increase of the process and quantity, it will continuously reduce the cost. In recent years, the speed is reduced by 20% every year, and the LED chip price factor is also included in the price reduction. In the same price, I bought a better product, so the LED chip has much room for price reduction.

2. LED application products are difficult to dissipate heat

The cost of heat dissipation should be maintained at 5%. The actual heat dissipation design is very simple. It is used in two directions: First, the shorter the path between the LED chip and the external heat sink, the shorter the heat dissipation design. The second is the heat dissipation resistance. That is, there must be enough heat to pass through the path and there must be enough "heat dissipation roads". This part of the cost is mainly in the structure, and the structural design accounts for about 20% of the lamps, and the cost for heat dissipation is not much. The biggest problem now is how to make more innovative and reasonable structural design.

3, LED application power supply

The power supply is the weakest link of LED lighting, which restricts the development of LED lighting. Nowadays, the design accounts for about 20% of the cost of LED lighting, and some are high. With the development of technology, the power supply is about 5-10%. LED light source compared with other light sources in the afterlife, in fact, the current cost is not high, especially LED environmental protection, energy saving, mercury-free, and the price of LED lighting fixtures are declining every quarter, LED lighting in a short period of time The price must reach a level acceptable to people.

Let's take a look at the patent profile of the LED industry:

Patent application disclosure trend:

National LED lighting fixtures have been in business since 2000, and reached a high peak in 2013 to 2015. It is obvious that LED companies are stepping up their patent applications.

The top four segments are mainly focused on:

F21Y101/02 miniature light source

F21S2/00 lighting system

F21V29/00 cooling or heating device

Fixing of F21V19/00 light source or lamp holder

It can be seen that the domestic LED lighting fixtures are concentrated in the light source, lighting system, heat dissipation, and the fixed layout of the fixed device required for construction.

Let's take a look at the top 10 LED lighting applications in China:

The domestic LED companies' technology layout in LED lighting fixtures will be weaker than the upstream technology investment, but this is not an obstacle to the needs of downstream enterprises. From the simple analysis in the above figure, the segmentation of LED lighting fixtures should be Will develop, that is, relative to others, such as H05B37/02 (control of circuit devices for general electric light sources), F21V17/10 (fastening of components of lighting devices), F21V17/00 (lighting device components) , F21V31/00 (the functional features of the lighting device or its system or the gas-proof or waterproof device of the components), the development potential of the small field is relatively large, so if the technology of the LED lighting is in a unique field Can consider the patent layout in this regard.

From another point of view, LED lighting fixtures in the intelligent control of this piece of research and development investment and patent layout is currently less, intelligent lighting is the future direction of LED lighting. One-button switch, latitude and longitude control switch light, adjust the brightness of light... Intelligent lighting allows the city to reduce the cost of human and material resources and energy waste while having a beautiful night scene. Therefore, many large companies have begun to compete for this piece of cake layout, you can refer to its related patent layout and route, choose the layout map suitable for its own development.

Finally, the first priority of the LED industry is to redeem lighting energy. This trend cannot be changed. As a green, energy-saving, low-carbon light source, compared with the traditional lighting method, the biggest advantage of LED light, in the same brightness, the energy consumption is only about 1/3 to 1/6 of the fluorescent lamp, and its life, It is 5 to 10 times that of fluorescent lamps. Despite this, with the wide application and increased use area, high-brightness playback, power consumption can not be underestimated. Therefore, LED companies still need to make products that are more energy-efficient from the technical level, reduce the economic burden of advertising owners, and certainly have a certain market share. At the same time, from the relevant authoritative data, once the LED lighting products form an “explosive” growth, they will be widely promoted to medium, high and low-end, saving China about one electric power generated by the Three Gorges Power Station every year.

The vertical layout of the multi-LED enterprise patent planning layout, in general, can be divided into three short time periods: short, medium and long-term:

(1) Short-term patent layout planning

The main task of the short-term patent layout is to provide patent protection for the upcoming LED products, carry out patent mining for various technical achievements in product development, carry out key deployment on its superior technical points, and complete the established patent application volume indicators; At the same time, in line with the medium and long-term development plan of the enterprise, the implementation of the medium and long-term patent layout, pay attention to the patent deployment of the next generation products, and initiate the laying of basic patent protection points.

During this period, a large number of patent applications were quickly accumulated at various technical points. By maintaining a certain number of patent applications and reserves, the company's patent pool will be initially established to provide necessary intellectual property support and guarantee for the commercial expansion of enterprises, so as to avoid large patent risks. In addition, while ensuring the quantity, the quality requirements cannot be relaxed. And consciously pay attention to the combination of different protection themes and patents to protect the content, to lay the foundation for the realization of patent portfolio.

(2) Medium-term patent layout plan

The main task of the medium-term patent layout is mainly to combine the medium-term product planning and commercial development of LED enterprises, as well as the patent application status of competitors, to complete the staged layout objectives, and initially complete the layout of protective patents and the layout of confrontational patents according to the needs. / or reserve patent layout, forming a certain number of patent portfolios.

At this stage, the patent application is a process of “quantity” and “quality”. The application volume will generally tend to grow steadily. The growth rate is basically consistent with the average growth rate of the industry. The purpose is to continuously improve and consolidate the patent pool that has been formed. Improve the coverage of patents in products, technologies and markets, further optimize the distribution of patents and improve the quality of patents.

(3) Long-term patent layout planning

The main task of long-term patent layout planning is to echo the long-term business development strategy, product planning route and patent positioning of the enterprise, and support the future market development of the enterprise. In general, LED companies' long-term patent layout planning should pay more attention to the overall value of patents. At this stage, the company's patent reserves have reached a certain amount of scale and structural distribution, and in some areas have a certain patent strength or even a dominant position, companies often begin to pay more attention to the following:

提升 Increase in the use value of patents and effective control of patent costs;

â—‡Provide patent operations and obtain additional income;

â—‡ Rely on the patent to gain control of the industry and actively promote the effective combination of its own patents and standards;

保持 Under the premise of maintaining its patent superiority and confrontation ability, the patent portfolio is structurally optimized to consciously remove redundancy in the patent pool.

At this stage, companies can consider abandoning patents or patent transfers for low-value patents. Moreover, based on their own economic strength and the growth of patent strength, companies can often adopt a more diversified way to improve their patent layout and supplement the patent composition in their patent portfolio, such as using cross-licensing, purchasing and forming with peer companies. Strategic alliances and other means.

Regarding the layout of patents, many teachers and big coffees in the industry are talking about it. There are also many companies asking how to layout or exploratory implementation of patent layout. Everyone is crossing the river. The layout of patents is definitely not a single road, but the design of all-round and multi-path belongs to the enterprise. “All roads lead to Rome”, enterprises must have a horizontal and vertical way of thinking about patents. There is depth. Let enterprises take more “detours” on the road of patents, and take less detours in product planning, layout, R&D, design, etc., or layout on the road ahead can only be the way they can go, even if they don’t go, they won’t Easy to let others go.
