Domestic intermediaries maddening overseas LED related
Recently, seven days (Beijing) Consulting Co. Ltd. (hereinafter referred to as seven days) has been announced, the successful acquisition of Seiko (Seiko) in LCD, LED Nearly 220 pieces of patent technology and OLED, these patents will be used mainly for domestic operations. Experts said, through a professional intermediary intervention can effectively help domestic enterprises to improve the efficiency and quality of access to foreign patent, reduce domestic enterprises Overseas patent The cost and risk of acquisition. At the same time, help to broaden the China enterprises to obtain overseas patents Channel .
The shortage of domestic enterprises overseas patent
In fact, from the current development of domestic part of the industry, widespread imported technology from abroad and digest, gradually realize industry self-development, and to seek overseas development in this process. In the seven days, the acquisition of LCD LED patents as an example, the current global LCD industry development in Japan, South Korea, the basic form of the Three Kingdoms Chinese pattern. Statistics show that, as of now, the most active in the world patent market USA Japan, South Korea and other countries, the company has a number of patented LCD America more, in a leading position, Chinese submitted by the applicant to apply for a patent America less.
"With the application amount is inversely proportional to Chinese, in the LCD industry production capacity ranking, LCD become the industry's most important product processing and exporting." Seven days Longxiang chairman in an China intellectual property news reporters.
With the expansion of market share and profitability improved, China, LCD manufacturers are increasingly facing competition from the international intellectual property rights pressure.Therefore, has emerged in the development of industry, the patent application is relatively backward and the risk of overseas litigation case, China's LCD industry and the number of domestic enterprises overseas patent application does not match the momentum of rapid development, domestic enterprises need to make up the short board of overseas patent.
It is understood, seven days of overseas "prey", also attracted a lot of attention of domestic enterprises. "For the seven days of the acquisition of patents we are currently evaluating, Seiko is very competitive with its rivals, in the liquid crystal display, liquid crystal display with the globalization of the market and diversified products, mobile phone LCD device etc.. As the operator of the subject, the legal status of products, and belongs to the area of this series of patents involved is very important, we look forward to more information, follow-up may try to carry out relevant cooperation and seven days." LED Industry Patent Alliance Secretariat Deputy Secretary General Wang Hua said in an interview with this reporter, LED lighting and derivatives industry patent concentration and reserves will become the norm, LED industry patent alliance itself is also actively carry out the "LED industry patent protection collection plan".
Intermediary institutions play professional advantages
Reporters learned that, at present, the construction of domestic enterprises overseas patent database, to the vast majority of patent applications, very few cases with overseas patent acquisition. The overseas patent expensive, there are institutional barriers, the reason for the acquisition is difficult, but also because enterprises lack the ability to patent acquisition information sources and channels as well as screening, bargaining and other aspects of the patent. In recent years, domestic enterprises have successful cases overseas acquisition of patents, but are Huawei, such as Lenovo, Alibaba and other giants, small and medium-sized enterprises are rarely heard.
"Predictably, with part of the industry in our country and the increasing demand for overseas enterprises overseas patent, patent acquisition increases the demand. The patent operators involved, to play their own advantages, to meet the actual needs of enterprises with professional services." Cheung said, he found in the process of negotiations with Japan Inc, as Japan LCD industry shrinking, many enterprises have the intention to sell the patent, the patent resource has been in other countries and regions of non patent entity (NPE) aimed at, and once these patents are "patent trolls" overseas acquisition, probably as to the enterprises initiated patent infringement litigation Chinese weapons, so as to cause huge losses China LED enterprise and industry.
"In the role of intellectual property increasingly prominent, specialized agencies engaged in the operation is the inevitable product of patent, patent operators have their own advantages and channels, the future we hope to strengthen cooperation with domestic and foreign institutions, in 'the LED industry patent protection, patent information collection plan' development and utilization, the formation of patent pool to improve the quality and strengthen exchanges, to jointly improve the domestic LED enterprises and industry patent competition ability, for domestic enterprises' to 'provide intellectual property protection and out of service." Wang Hua said.
Welding method of LED lamp beads
There are many welding methods for LED lamp beads on the chip, and the following is one of the commonly used methods for reference. First, use an electric soldering iron to heat some soldering tin on the positive and negative electrode pads of the lamp bead (the soldering tin must not be too much, otherwise, the positive and negative electrode pads will be connected once heated with a hot-air gun), then use a hot-air gun to heat the positive and negative electrode pads at the same time, after the tin melts, use tweezers to place the positive and negative electrodes of the lamp bead on the corresponding pad.
LED beads change color? These six reasons are worth noting
LED is the light emitting diode, which is a semiconductor solid light emitting device that converts electric energy into light energy. Its core is the PN junction. In addition to the forward conduction, reverse cut-off and breakdown characteristics of the general PN junction, it also has the light emitting characteristics under certain conditions. Its structure mainly includes the following parts: lead, bracket, encapsulation glue, bonding wire, LED chip, solid crystal glue and phosphor. The discoloration failure of LED lamp bead is closely related to its material, structure, packaging process and service conditions. The following will analyze the causes of its discoloration through specific cases.
Common types and application fields of LED lamp beads
There are many kinds of LED light sources. Different LED lights have slight differences in the lamp beads used in their internal structures. Today, I will make a comprehensive and systematic scientific introduction to the common types of LED lamp beads for your reference.
LED lamp beads are also called light emitting diodes. It has a wide range of applications. Its luminous colors include red light, emerald green light, yellow green light, yellow light, purple light, blue light, white light and orange light. The above is monochromatic light. It can also be made into two or three colors.
How to identify whether LED lamp beads are pure gold
The gold wire used to package LED lamp beads contains more than 99.99% gold. It is produced by drawing gold from this material. In addition to 99.99% gold, this gold also contains less than 1% other trace elements. One of the core components of LED lamp bead packaging is gold wire, which is the bridge connecting the luminous chip and the welding point, and plays a decisive role in the service life of LED lamp bead. So how to identify the purity of gold thread?
