LED industry stepped into the stage of process and technology innovation

According to the new issue of “Semiconductor Lighting Energy-saving Industry Planning” issued by the National Development and Reform Commission of China, by 2015, the LED lighting industry structure will be further optimized, forming 10-15 master core technologies, possessing more independent intellectual property rights and well-known brands, and quality competition. Strong leading company. This indicates that the adjustment and upgrade phase of China's LED lighting industry has come. For LED lighting products, innovation in the process and technology is urgently needed. Technological changes and efficiency changes will more reflect the difference between different companies.

The 2013 Guangzhou International Lighting Fair, which has just concluded, has passed a new trend in the development of the LED lighting industry, focusing on the latest product solutions and emerging applications of upstream and downstream companies in the industry chain.

Smart dimming “SHOW” is a general trend to replace the traditional incandescent lamp with wonderful LED lighting. However, one of the focuses of current market applications is that since the incandescent lamp is a linear load and the operating current generally exceeds 50 mA, the flicker phenomenon does not usually occur. In order to achieve the same extreme, smooth, and flicker-free performance as the conventional luminaires. Dimming effect, manufacturers are trying to improve the technical quality of LED lighting dimming development in different technical routes.

With a variety of innovative technologies, LED lighting dimming has evolved from simple switching, on/off mode, to a variety of lighting modes that can be adjusted according to the site's different contexts to meet more user-friendly application requirements. For example, the user can perform color matching operation of the LED lamp according to the usage scenario, which greatly enriches the user's experience.

LED wireless dimming control system does not need to replace or install any new power lines, and at the same time it can help users better manage lighting equipment. Its simple, convenient, cost-saving and free positioning application advantages have been recognized by many market participants. Is increasingly showing the characteristics of intelligence, energy saving and environmental protection.

LED lighting flashes into stars. Philips Lighting's star product, the HUE bulb, is a highly customizable lighting product that provides more than 16 million color changes for electric lights through a combination of three built-in LEDs including green, red, and blue. The selling point is also its perfect multi-level customizable effect, which can be adjusted by the user through the iOS application or the software downloaded on the Philips website.

OSRAM's LEDTOUCH track spotlight is a stylish design from Europe. It combines the advantages of LED's high efficiency, longevity, and no infrared, together with full color temperature, high color rendering, light pass and adjustable angle, making this LEDTOUCH Track spotlights can show perfect flexibility and elegant design in retail store lighting, easily respond to different lighting needs, and become the first choice for key lighting.

In March of this year, Taiwan Everlight Electronics Industry Co., Ltd. established “Yiguang Lighting Management (Shanghai) Co., Ltd.” in the mainland, formally entered the domestic lighting market, and developed a series of new LED light source products, including 3W, to meet the needs of the local market. And 5W all-around bulb, SL-60LF full-circle bulb, 1400 ultra-high lumen SL-60F bulb, and the full range includes high power, medium and low power and COB components.

Improve the quality of all aspects of the industrial chain flip-chip ceramic base COB, that is, FCOB products, based on flip-chip welding technology, the use of non-gold wire package, the light source size and light emitting area is more compact, convenient secondary optical design, and the absence of the constraints of the gold wire The light source is more reliable and withstands high current surges. The product adopts a ceramic substrate, which has better insulation and excellent performance in high pressure resistance.

Dow Corning's phenyl silicone packaging material has excellent thermal stability and can be widely used in many high-power general-purpose lighting products for 5-50W LED chip-on-board packaging structures. Compared with methyl technology, phenyl silicone packaging materials generally have stronger gas barrier properties, which can prevent the silver electrode from becoming black due to moisture and corrosion. Since these electrodes also have dual roles as LED retroreflective elements, improving the gas barrier properties can better maintain the LED's light output performance and reliability.

Ming Wei (Guangzhou) Electronics Co., Ltd. developed from 12W to 320W all kinds of LED lighting power supply products with high stability, high efficiency, and dimming capabilities, In addition, LED display power products show ultra-thin high-efficiency LED display Screen dedicated power application technology.

The ability of LED lamps to adapt to various outdoor complex environments (such as climate, water, dust, acid and alkali corrosion, etc.) is getting more and more attention. In particular, high-power LED street lamps are exposed to the heat dissipation problems in the outdoors; lightning-induced weather often causes the problem of broken buildings and lighting fixtures; the protection performance of the lamps and lanterns in the rain, water, etc., these need to be selected in the lighting components, design In the next step.
