The top ten domestic LED lighting patent applications are released: Ocean King / Op Lighting / Qin Shang Optoelectronics top three

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, at any place, and how to do it. 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 of all, let's take a look at the basic situation of LED lighting: LED lighting is the collective name of LED lighting, refers to the device that can transmit, distribute and change the light distribution of LED light source, including all LED light source for fixing and protecting LED light source. All the required zeros, components, and wiring accessories necessary to connect to the power supply. Simply put, it is the LED light source, the heat sink, the lamp housing, the drive power, 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 lamps, 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 that currently plague 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 do not have the core technology in China, even though our LED application products are capable of manufacturing. The world accounts for 50%, and the share accounts for 50%, but it is the lowest link in the profit segment. 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 size wafer manufacturing 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 cooling heat dissipation cost should be maintained at 5%, the actual heat dissipation design is very simple, to live in two directions: First, the shorter the LED chip and the external heat sink parts path, the shorter, the shorter your heat dissipation design Second, the heat dissipation resistance is to have enough heat to pass to the path and also have enough heat dissipation road. This part of the cost is mainly in the structure, the structure design accounts for about 20% of the lamps, and the heat dissipation cost is not much. . The biggest problem now is how to make more innovative and reasonable structural design. 3, LED application power supply Power is the weakest link of LED lighting, restricting 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%. The LED light source is compared with other light sources. In fact, the current cost is not high, especially LED environmental protection, energy saving, mercury-free, and the price of LED lighting is falling every quarter, LED lighting in a short period of time The price must be at a level that people can accept. Let's take a look at the patent profile of the LED industry: Patent application disclosure trend: As shown in Figure 1, the national LED lighting fixtures started in 2000, and reached a high peak in 2013 to 2015. It can be seen that LED companies are stepping up their patent applications. Figure 1 LED patent application trend

Disc Harrow Bearings:

Disc Harrow bearings are also named Heavy Duty Disc bearings, are made with Triple Lip seals to protect from the corrosive environments. This seal is a one piece shield cover with three molded contact seals. Bearings have Round bore and Square bore, there be Relubricable and Nonrelubricable two type.Stanard relubrication feature is a drilled hole in groove. Borine's Disc Harrow bearings are basis on good quality and competitive prices, repalcement for John Deere, Case-IH, krause, Massey, Great Plains, AMCO, Kewanee, KMC, New Holland, Sunflower, White etc OEM parts.
