diffuses light like the incandescent light bulb

The new bulb gives off almost 1160 lumens, and consumes 11.4 watts. It can be available in E26-base, and diffuses light like the incandescent light bulb. With the new bulb, it can not only improve the brightness, but also reduce power consumption.

Nuclear power shortage has driven up demand for LED lamps after the March 11 earthquake. Hitachi Appliances will diversify LED bulbs on brightness and light distribution to cater different demands from customers.

JEDEC Solid State Technology Association, the global leader in the development of standards for the microelectronics industry, announced the publication of a new series of standards for component level testing of high-brightness/power LEDs. Development within JEDEC’s JC-15 Committee involved LED industry leaders, and resulted in the new JESD51-5x series of standards aimed at thermal characterization of power LED components.  The series is in compliance with the International Commission on Illumination (CIE)’s existing LED measurement recommendations.

As the efficiency of power LEDs has improved over time (now in the range of 20-40% depending on the type of LED), the use of high-brightness/power LEDs as a lighting source has become widespread in diverse applications in numerous industries. In these use cases, thermal design is critical in order to ensure expected LED lifetimes and light output, and the design process requires accurate thermal data for LED components. Prior to the publication of the JESD51-5x series, a lack of widely accepted thermal testing standards for power LED components meant that published data sheet information was often questionable. Therefore, development of the new standards was urgently needed.
