The traditional LED light source has a large light-emitting surface. When matching a small-angle secondary optical device, the lamp is bulky and is not convenient for the appearance of the lamp structure. Under this trend, high-density COB with high-intensity beam output characteristics and no gold wire package structure has become a dazzling star among many LED light sources, and has been widely used in the middle and high-end, especially in the commercial field.
Previously, market research firm Strategies Unlimited released the latest market research report "Global General Lighting COB LED Market" forecast, the overall market will have significant growth, from $1.5 billion in 2014 to $4.4 billion in 2020, and from 2014 By 2015 the market will experience a very impressive 40% growth. Analysts believe that "COBs have better light distribution and design flexibility than other package types, which makes them more adaptable to demand, whether it is direct lighting applications, large lumen applications, or both."
Currently, the Cree CREE CXA HD series, Citizen CITIZEN HI series and Toyo Toyota YOLL HR series on the market have technical start-up and brand awareness advantages in COB light source, but in the current fierce market competition, the first-mover advantage is gradually lost. Under the premise that the main material chips, substrates, glues, etc. of COB light source have been localized, COB product requirements are becoming more and more diversified, and domestic enterprises rely on cost performance and service to become more and more incomparable in the market competition.
As the only manufacturing company in mainland China that can realize high-power flip chip, integrated chip, and gold-free package LED chip-level light source, module light source, and light engine production, Jingke Electronics will be at this year's Guangzhou International Lighting Exhibition (referred to as | The “COA High Power Seriesâ€, which includes ceramic-based and metal-based products, is worthy of attention. Adopting a series of products based on APT patented technology-Flip-chip soldering technology, it realizes gold-free and solid-free plastic package of single-chip and multi-chip modules, with high brightness, high light efficiency, high reliability, low thermal resistance and color. Good consistency and many other advantages.
In particular, the COB light source using a ceramic substrate and the flip-chip non-gold wire packaging technology are technically lower in thermal resistance and more direct in heat dissipation than conventional LED package products. High reliability, electrical connection surface can withstand high current impact, chip thrust can be greater than 2000g. As an LED module device, it becomes a standardized component of the luminaire, which greatly simplifies the assembly process of the luminaire and provides a broader space for the luminaire design.
This year, Guangya Exhibition will launch the 5050 and 7070 products, which are mainly used in commercial lighting, home lighting and architectural lighting. The product features continue to inherit the advantages of high reliability and high efficiency.
During the June 9th, 2015 -12 Daylight Asia Exhibition, Jingke Electronics will also launch a series of TV backlight products, mobile phone flash products, lighting sources and optical components, including the latest CSP products, high color gamut TV backlight Source series products, dual color temperature mobile phone flash light source products, booth number is 10.2 Hall A01.

Small computer system interface (SCSI) is an independent processor standard for system level interfaces between computers and intelligent devices (hard disks, floppy drives, optical drives, printers, scanners, etc.). SCSI is an intelligent universal interface standard.
In addition to SCSI, IDE is also a very common interface. From the point of view of ease of use, IDE is more suitable for ordinary users. In addition, personal computer users not only need to configure a few peripherals, but also do not require high speed. Therefore, it is more appropriate to choose IDE interface. In addition, IDE also has the characteristics of high performance price ratio and wide application. Although the SCSI interface has many incomparable characteristics, the price of the interface and its peripherals is too expensive to be borne by ordinary users, which determines the limitation of its actual use range.
1. The working mode of IDE requires the whole process participation of CPU. When the CPU reads and writes data, it can't perform other operations. In this case, in the multitask operating system of Windows 95 / NT, the system reaction will be greatly slowed down. The SCSI interface controls the data reading and writing operation completely through the independent high-speed SCSI card, so the CPU does not have to waste time to wait, which obviously can improve the overall performance of the system. However, IDE interface has also made great improvements to improve this problem. DMA mode can be used instead of PIO mode to read and write data. DMA channel is responsible for data exchange, which greatly reduces the CPU consumption. However, comparing the CPU utilization of SCSI and IDE, we can find that SCSI still has considerable advantages.
2. The scalability of SCSI is larger than that of IDE. Generally, each ide system can have two IDE channels, with a total of four IDE devices. The SCSI interface can connect 7-15 devices, much more than IDE, and the cable connected is far longer than ide.
3. Although the price of SCSI device is higher, compared with IDE, the performance of SCSI is more stable, durable and reliable.
