Blu ray LED PLC: Matsushita Yuan innovation technology hotspots

In October 30th, Panasonic Electrical Co. Ltd. (China) held in Beijing to "create a feasible scheme to build the dreams of the future" as the theme of the exhibition will showcase the technical exchanges, Matsushita in the field of electronic components of leading-edge technologies and key products. Read the show, amazing Panasonic in the powerful behind the whole product, but there is such a long product line and advanced components and technology products. The person in charge of the company's figures are even more surprising, the entire Panasonic sales in China 2/3 from industrial products.

Blu ray products: greatly improve the optical disk storage capacity

Disc (Blu-ray, abbreviated as BD) uses a shorter wavelength blue laser to read and write data that can record or read more information per unit area. Therefore, Blu ray greatly improves the storage capacity of the disc, and provides a medium for the storage of high quality audio and video as well as high capacity data.

So far, Blu ray is the most advanced high-capacity optical disc format, BD laser technology has made great progress, so that people can be stored on a single disk up to 50GB document file, which is the existing (Dan Die) DVD 10 times. In speed, Blu ray recorders can reach 4 speed.

The huge storage capacity of Blu ray products for high-definition movies, games and large capacity data storage brings the possibility and convenience, will greatly promote the rapid development of high-definition entertainment industry.

We saw the scene in the show, show the blue solution Panasonic, BD player: large screen also perfect reproduction of FHD picture playback, high quality BD-Video; reduce noise and playback of high contrast images through various design schemes combination; high reliability BD playback, playback and support existing DVD specifications of CD the. BD burner: support up to 18 hours of FHD image quality, the 5.1 channel sound data recording function. BD test: the world's first CD by BD player technology integration into the double layer corresponding to each test disc; BD test disc support all 1920 x 1080 full screen high-definition playback; on partial core, emphasis on heart, 100 kinds of surface scratch disk problems test and quality management.

Panasonic electric (Chinese) related personnel limited, except Japan, Europe and other overseas markets, they also hope that the product can be obtained in addition to Panasonic Blu ray machine form outside the module in the form of sales in Chinese, and related to the production of domestic customers and common industry promotion.

High efficiency fluorescent lamp: energy saving effect is remarkable

At present, energy saving, consumption reduction, environmental protection has become the focus of the world, the lighting products in the production process of a large number of energy consumption and the impact on the earth's environment has attracted more and more attention. Therefore, how to create a comfortable lighting environment in the building lighting, energy conservation, environmental protection is a major technical and economic issues, but also to enhance the competitiveness of manufacturers in the industry weapon.

Panasonic launched e-Hf high efficiency fluorescent lamp and e-Hf combination of intelligent electronic ballasts so that the optical efficiency of up to 104lm/W. The person in charge of the company said, e-Hf high efficiency fluorescent lamp with the same power consumption of ordinary fluorescent lamp, the brightness increased to 1.6 times the same brightness, energy saving of 32%. Such a high efficiency, through the production of Panasonic T8 (25.5mm) 32W high frequency special fluorescent lamp, equipped with Matsushita Electric production of intelligent electronic ballast lamps drive light. Compared with ordinary T8 tube (25.5mm) inductance ballast lamp, under the same brightness conditions, can save 30% of electricity. With the industry as an efficient 28WT5 tube (16mm) compared with electronic ballast lamps, can save 6% of the electricity, and can reduce the number of tubes in the use of 30%.

The responsible person told reporters a detailed explanation, Matsushita was through two aspects of light source and change of ballast to achieve energy efficient: first, the traditional fluorescent lamp has been improved, such as phosphor, encapsulation, gas composition and pressure, the filament design has changed; second, the integrated circuit control to achieve stable output of ballast., to achieve the effect of constant power output.

High efficiency and energy saving products belong to the mandatory use of domestic demand, the current e-Hf fluorescent lamp utilization rate has reached 60%, has been widely recognized by customers and the community. In China, e-Hf efficient fluorescent lamp in a few home appliance chain has been used, such as the United States, preliminary estimates, 5 years can save electricity 130 million yuan, in the prerequisite to achieve satisfactory effect of lighting, saving considerable energy consumption and cost savings for the enterprise.

LED:GaN outstanding advantages

In recent years in the international GaN based materials breakthrough, developed a highly efficient blue and white high brightness LED, can not only realize the large screen and full color display, but also has the potential to replace the incandescent lamp, the fluorescent lamp for lighting project, so as to completely change the current human life, so the GaN substrate LED by the industry more and more attention.

Panasonic at the scene shows a variety of applications based on GaN substrate LED, including LCD TV backlighting, outdoor and landscape lighting, as well as home lighting. The semiconductor sales company ran Liang said that the exclusive substrate GaN technology in the global Panasonic Corp, compared with the traditional LED sapphire substrate, GaN substrate is the advantages of good conductivity, good uniformity of luminescence layer; thermal conductivity, thermal conductivity is 5 times the same sapphire light-emitting layer and refractive index; therefore, the light output efficiency is high; the lattice constant (luminescent defect density within the layer) is sapphire below 1/100, therefore, the luminous efficiency and reliability of the good.
