waterproof led wall pack with sensor manufacturers solid-state lighting LED products and technology seminars were held on January 26 in Taipei and January 28 in Tainan. In an interview on site, in the first session of the solid-state lighting market trend, mentioned that there are four main trends in LED solid-state lighting, including luminous efficiency (100lm\/W-180lm\/W), lm\/$ (300-1000), and luminous flux maintenance Rate (lm maintenance 10kh~50kh), color rendering (70-90). Why is luminous efficiency so important? Simply put, luminous efficiency is increased by 20%, and lighting costs can be reduced by 50%. Therefore, in lighting-level packaging, has optimized the epitaxial and chip design, optical glue and optical design, reflector, phosphor and manufacturing process. At present, most of the chips are 2D design technology. mentioned that for future chip design, is currently researching and developing 3D nano-column chip technology (Core-shell InGaN \/ GaN Microrod LED Structure), mainly hoping to increase per unit wafer The effective light-emitting area below. In the introduction of LED products in the solid-state lighting market, offers a variety of LED product lines, including medium-power Duris series and high-power SOLERIQ COB product series. Observing the development of in Taiwan, the market demand for medium-power and high-power COB products is growing. Therefore, also focuses on the development of both product lines. Take Duris products to look at Duris E3 HE (0.2W 3014), Duris E5 HE (0.5W 5630), Duris S5 HE (1W 3030 LED). At the same time, 3000K is also one of the main color temperatures in products, so product development includes CRI 70, CRI 80, and CRI 90 to meet the requirements of the lighting market. At the same time, the development of luminous efficiency is also very important.
