Matsushita Electric developed the industry's highest brightness white LED module

Matsushita recently developed a new type of white light emitting diode (LED) module, the module under illumination and 100W incandescent lamp under the same power consumption can be reduced to about 1/4 (release). As the expansion of the light angle of the model, in the module of the average illumination and 40W incandescent lamp in the same case, the power consumption can be reduced by about 37%.

The company said that the module is below the average illumination and white LED modules are the highest in the Japanese lighting industry. Specifically, in the use of power consumption when the illumination of the 25W, the light angle of small models in the module is about 200lx below, the illumination angle of the model is about 20lx. Mainly for lighting equipment, plans to market in June 20, 2005. It will provide 16 kinds of products, such as white color temperature, light angle and module shape. All models can be up to 40 thousand hours. This product will be displayed on the "Lighting Fair" at the BigSight International Convention and Exhibition Center in Tokyo from March 1, 2005 to 4.

The white LED module on the blue LED chip with the use of fluorescent materials. The fluorescent material is processed into a plate shape and is arranged on a blue LED chip. The common white LED module using this chip is usually coated with fluorescent material. Compared with the original method, the method of using plate fluorescent material can reduce the nonuniformity of color temperature to 1/5. Matsushita Electric was in August 2003 on this method of technical publication. However, the heat dissipation through the module design and lens design efforts, while achieving high light and long life. When the technology was published in August 2003, the module was designed to be the same as the 40W incandescent lamp, power consumption was more than and 20 W. Under the basic conditions of the same power consumption to achieve the 100W level of illumination, so the brightness increased by nearly 2 times.
