Guangzhou International Lighting Exhibition ushered in a grand opening, the most not to be missed is the brightest booth of this year's Guangya Exhibition -12.2 Hall E40's Zhongke core source, kilowatt-level COB lighting the audience!
It is understood that Fujian Zhongke Core Source Co., Ltd. is jointly invested by the Haixi Research Institute of the Chinese Academy of Sciences (the Institute of Material Structure of the Chinese Academy of Sciences) and the Fujian Federation of Enterprises and Entrepreneurs, as the only research institute of the Chinese Academy of Sciences, Haixi Research Institute (Institute of Physical Structure, Chinese Academy of Sciences) The LED technology transfer base and industrialization platform have the core technology of LED ceramic packaging.
In the past two years, LED market and technology have been continuously developed and changed. COB has become a must for all LED packaging companies. International manufacturers are trying to open up the gap with domestic enterprises with high-quality and high-efficiency COB products. .
“From the perspective of the market, Chinese companies are relatively weak in high-power ceramic packaging, but in some very important areas, such as portable lighting, outdoor lighting, industrial lighting, automotive headlight lighting, etc., all are packaged in ceramics. Power. Although the package and COB package are very hot, the chip is also very hot, but the high-power chip and ceramic package have a very important position in the LED field. In some special applications, it The use of ceramic packaging technology and high-power chips is the best. Zhongke core source is very good to achieve and apply ceramic fluorescent dressing technology." Ye Shanghui, executive vice president of Zhongke core source mentioned.
The Zhongke core source relies on the Chinese Academy of Sciences to achieve technological innovation and challenge the 1000-watt COB technology limit. Ye Shanghui also introduced the ceramic package's corrosion resistance, high temperature resistance, vibration resistance and moisture resistance reliability better than plastic packaging. Features.
Four pioneering advantages of K-COB technology:
â¶, core technology: Chinese Academy of Sciences technology transfer:
The laser ceramics of the Institute of Physics and Physics of the Chinese Academy of Sciences has a key performance that exceeds the advanced level of foreign countries. Laser ceramics are known as "the king of ceramics". The laser ceramics have the characteristics of high strength, high hardness, corrosion resistance and high temperature resistance. They are the purest, the best optical quality, the highest performance and the most difficult. The integration and representation of the highest technology in ceramics.
〠, core material: transparent fluorescent ceramics:
With the technical foundation of laser ceramics, process improvement, excellent performance and stable LED luminous efficiency and luminescence performance, and large-scale production of transparent fluorescent ceramics. Fluorescent ceramics have superior thermal and luminescent properties.
â¸, core patent: Baiguang patent low thermal resistance package structure patent:
Focusing on the transparent fluorescent ceramics' own intellectual property rights, it integrates high-power integrated package design, heat dissipation design, optical design and integration of light and heat modules to form its own patent chain around the integrated white light source and low thermal resistance packaging technology. .
â¹, core components: Photothermal integrated light source module:
Solve the key technology of high-power integrated COB light source thermal management, and realize high-power high-density small-angle illumination light engine module. The three-dimensional heat conduction key module has better uniform heat dissipation capability, high-density luminous flux output, and high-quality small-angle light distribution.
K-COB technology limits:
â¶, ultra high power + ultra high density:
The 35mm diameter light-emitting surface is loaded with a chip-mounted chip package to achieve a power of 600W.
The 50mm diameter face-loading chip is mounted on the chip package to cross the 1000W mark.
â·, high luminous flux + small luminous surface:
The luminous flux of a single K-COB source with a diameter of 50 mm has reached 100,000 lm.
â¸, high power + small angle light distribution:
The high power density kilowatt COB light source module achieves ultra-small angle light distribution.
â¹, high reliability + high cost performance:
The K-COB light source module achieves three years of zero light decay, stable performance and high cost performance, creating value for customers.
"In normal life, LED has gradually replaced traditional lamps such as metal halide lamps, fluorescent lamps, energy-saving lamps, etc., and in the field of traditional high-power over 1000W outdoor lighting, LEDs are limited by light, light intensity, color temperature, color rendering index, etc. The popularity of these areas is mainly due to problems in heat dissipation. For high-power COB packages, antipyretic is a crucial factor affecting their long-term reliability!" Ye Shanghui finally mentioned.
Yuhai Company is engaged to research and development of piezoelectric products and related piezoelectric products, the related piezoelectric products includes the piezo sensors and transducer.
The ultrasonic transducer is a kind of transducer that converts the ultrasonic signal into electric signal, or vice versa. Ultrasound transmitter and receiver is a transducer that can transmit and receive ultrasound. Ultrasound sensor is a kind of sensor, in essence, it is also a transmitter and receiver. The working principle of this kind of equipment is similar to that of radar and sonar. Active ultrasonic sensors can emit and receive reflected waves, and determine the distance of the target by measuring the time interval between transmission and reception. Passive Ultrasonic Sensor is actually a microphone that can convert ultrasonic signal into electrical signal.
According to the working principle and materials used, the ultrasonic transducer has piezoelectric transducer, electrostatic transducer (capacitive transducer), magnetostrictive transducer, electromagnetic acoustic transducer, mechanical transducer and other types [1].
