China's lighting electrical output and export volume rank first in the world. For example, the annual output of energy-saving lamps in China accounts for more than 85% of the world. Most of the energy-saving lamps used in the world come from China. In the new technology field of LEDs that lead the market trend, China's enterprises package more than 80 billion LED devices annually. The first one. In addition to scale advantages, domestic lighting companies are gradually gaining the advantages of technology and intellectual property. For example, in the lighting suppliers of the Athens Olympic Games, in addition to multinational companies such as Philips and GE, some Chinese companies also stood out and won the recognition of the Athens Olympic Organizing Committee with superior independent intellectual property rights.
The Olympic Games provided an opportunity for the collective outbreak of Chinese lighting companies. Although there are only dozens of lighting electrical products suppliers selected by the Beijing Olympic venues, these Olympic lamps use new materials, chips, software, boards, controllers, pipelines, IPv6 lighting control networks, solar cells, LEDs and SMDs. Loading equipment, etc., comes from hundreds of companies upstream and downstream. The large-scale procurement of Beijing Olympic Games provided an opportunity for the Chinese lighting industry to collectively display its technology and technology. From the perspective of the patent strength of local enterprises, the Beijing Olympic Games, where local lighting appliances play a leading role, will create a new level of Olympic history in terms of technological content and environmental protection.
Judging from the current situation, most of the Beijing Olympics projects have selected lighting products from local companies. For example, the lighting appliances of Guangdong Dongsong Sanxiong Electric Co., Ltd. have successfully settled in 15 Olympic venues, and are the domestic enterprises with the largest number of Olympic venues. Qingdao Shibajia Electronic Technology Co., Ltd. provides more than 80% of the light source products of the Olympic solar lighting project. Beijing Liangye Lighting Group is the sponsor of the National Stadium Project of the Beijing Olympic Games and the designated supplier of the only lighting system of Bird's Nest. Beijing Xingguang Group also provided energy-saving lamp products for the seven Olympic venues in Beijing, and contracted all lighting equipment projects for the Olympic beach volleyball court.
In addition, the Water Cube is the only Olympic venue in the world that uses LED high-tech lighting equipment. The China Power Technology Group is one of the main design and implementation units of the LED lighting project. With the world's advanced lighting development and professional lighting design software, Shenzhen Ocean King Lighting Engineering Co., Ltd. designed and developed lighting equipment for the six Olympic venues. Zhongshan Zhenhui Fire Equipment Co., Ltd. provided tens of thousands of fire emergency signs and fire emergency lights for the Olympic venues. Ningbo Liaoyuan Lighting Co., Ltd. also provided tens of millions of high-power LED lighting for the Olympic project. In addition to the above-mentioned enterprises, Jiangsu Huahui Lighting Electric Co., Ltd. also provided lighting products for the construction of Olympic venues and related facilities. Therefore, Beijing Olympic lighting electrical suppliers come from Guangdong, Shandong, Beijing, Zhejiang, Jiangsu and other places, the five major lighting gathering belt, its Olympic lighting products use LED, solar energy and other mainstream technology routes, with strong regional, technical representatives Sex.
From the perspective of the patent deployment of these enterprises, China's lighting industry has accumulated a strong intellectual property strength. The search shows that the products and method patents are mainly distributed in the following fields:
Circuit design
For example, the document No. 200610051162.3 relates to an electronic circuit for a lighting fixture. It sets the filter component on the input end and sets the filter component in the flow-by-flow circuit to strengthen the isolation and filtering capability of the circuit. Document 00610051161.9 relates to an electronic circuit for a lighting fixture. It sets the filter component in the flow-by-flow circuit to provide internal loop and superposition for the high-frequency current generated by the excitation circuit, strengthens the power factor correction capability of the circuit, and superimposes the high-frequency signal into the charging capacitor, so that the high-frequency current is reapplied. The document No. 200510003945.X relates to a switching control circuit of a near-near xenon lamp group, which is mainly composed of a main controller, an electronic ballast and a second switch, wherein the second switch is respectively connected to the electronic stability circuit and the near lamp group and the remote lamp. Between groups, the switching action is controlled by the main controller, and the electronic ballast can form a loop with the near lamp group or the remote lamp group to realize the purpose of electronically switching the near-far light.
technological design
For example, the document No. 200510102388.7 relates to a YAG wafer type white light emitting diode and a packaging method thereof. First, it uses a YAG single wafer to convert part of the blue light emitted by the GaN-based inorganic semiconductor LED die into another one or more ideal wavelengths, and then the remaining unconverted blue light emitted by the LED die is converted from a single wafer. The light mixing of the ideal band produces white light. Document No. 200710027993.1 relates to a side light emitting diode and a manufacturing process thereof. The diode comprises a die, a package body, a bonding wire, a package body bracket, and the like; the package body bracket adopts a metal substrate having a cavity structure, the metal substrate is divided into two parts insulated from each other to form two electrodes, and the die is placed on the metal substrate. In the cavity, the bonding wires are respectively connected to the die electrode and the other electrode of the metal substrate.
High ceiling light
For example, the document 200420043912.9 relates to a high ceiling lamp comprising a lamp housing base, a current processing device disposed in the lamp housing base, a lamp socket disposed on the lamp housing base and connected to the current processing device, and a lamp socket disposed on the lamp socket. The light bulb further includes a lamp cover disposed outside the bulb and connected to the base of the lamp housing. Wherein, a vibration damping device is provided between the lamp holder and the lamp housing base to protect the bulb from various vibrations, and a tensioning device for ensuring reliable contact between the bulb contact and the lamp holder contact may be included.
Solar lighting
For example, the document No. 200410064379.9 relates to a suction cup type solar cell test platform control device and method. The device comprises: a positional switch mounted on the contiguous piece, the test, the laminated table top, a rising stroke switch on the lift guide, a descending stroke switch, a suction cup pneumatic mechanism, a programmable controller and a test instrument. It uses the programmable control device to servo control the pneumatic mechanism and the test instrument, and adjusts the vacuum degree of the suction cup to adapt to the continuous production of various plate solar cells.
