A new generation of I-core TM high-power 45 Mil LED chip, through the design and configuration of special metal electrodes, to optimize the light extraction efficiency, with a more stable chip structure, the original company in the market, light effects The leading chip brightness is increased by about 10~15% again, driving 350mA at room temperature, with the low voltage characteristic of the original vertical LED, the light efficiency has exceeded 120 lm/W, and the new generation product also has 40mil I in addition to 45mil. -core TM, the chip offers customers different options.
SemiLEDs, which manufactures high-power LED chips for lighting , its company's features focus on innovative technology, subverting conditions that cannot be achieved by traditional processes, and successfully mass-producing high thermal conductivity metal alloys as the vertical structure of the substrate . Power chip, and used in domestic and international street lights, wall washers, indoor and outdoor lighting and high-priced mobile phones. Because the thermal conductivity of the substrate of the metal alloy reaches 400W/MK, the Rth value is only 1/8 of the traditional sapphire substrate, and the Vf is also significantly lower. This characteristic makes the LED conduct heat quickly, effectively reducing the temperature of the node (Tj), in thermal equilibrium. The post-brightness performance (lm/w) is much higher than that of conventional chips and also has a better lifetime performance.
Over the past year, the company's chip brightness has increased by more than 30%, and sold in the market, because the customer response is very good, since July 2009, the expansion of production capacity has once again failed to meet market demand, it is understood that Xuming plans The chip factory added in Nanhai, Guangzhou, will increase production capacity several times in October in response to market demand.
According to Xu Ming's Road Map, after June this year, it is expected to launch the latest products. The production target by the end of 2010 is above 150 lm/W. Xu Ming Optoelectronics said that from the current progress, it is very optimistic.
