TOYOTA synthetic use of products to achieve the highest luminous efficiency in the industry 170lm/W white LED

Japan TOYOTA synthesis in the "fourth session of a new generation of lighting technology exhibition" (January 2012 18 ~ 20 days, Tokyo International Convention and Exhibition Center on Ming) discloses new products of white LED with higher efficiency, greater flux.

Through the realization of the high efficiency of the product 3528 package (package size 3.5mm * 2.8mm), light emitting efficiency from the original 150lm/W (input current of 20mA (170lm/W) to improve the input current of 20mA) to realize the white LED products. According to reports, although the enterprise has reached the level of efficiency at the research level, but as a product can be mass production, 170lm/W luminous efficiency is the highest level in the industry. Technology to improve efficiency. New products are currently sample supply, production is scheduled to supply in April 2012. Will be equipped with fluorescent lamp type LED lighting and basic lighting equipment.

TOYOTA synthesis also demonstrated a large flux of 2000lm grade products. This is a multi chip COB product that is available in the FU package (input current for 470mA time flux of 2000lm) and FC package (input current for 1500mA time flux of 2000lm) two products. Power consumption, FU package for 20W, FC package for 25W. Currently two products have been sample supply. Production time set in April 2012.

FU packaging and FC packaging packaging substrate and LED chip packaging are made of inorganic materials, thereby improving the heat resistance. In addition, the FC package is based on flip chip packaging, the LED chip is directly packaged on the packaging substrate, thereby achieving high reliability and high heat dissipation. In addition, the miniaturization of the LED chip is achieved by reducing the packaging interval. Because of the large light flux can be obtained through a small package, the FC package is the most suitable for the small light source with light intensity. Due to the use of a package can be, it can also prevent the occurrence of multiple Shadow (Multi), when the light shines on the object when the shadow of multiple objects.
