NHK in July 7, 2008 opening of the Hokkaido Toyako summit of the live part of the trial in the portable fuel cell power systems and LED lighting (Figure 1).

Portable fuel cell power system and the NHK in the February 2008 release of the same product by NHK and Hitachi joint compaq Presario NX9010  development. This is the use of a pump and fan of the active-type direct methanol fuel cell. Output power of about 100W, a 500mL use of the fuel cartridge (methanol fuel concentration of 40%) can power about two and a half hours. In addition to the two can be equipped with TV cameras, such as the power supply XLR4 needle (DC16.8V) export terminal, but also for the two television cameras with rechargeable lithium-ion rechargeable battery pack.

In the past, disaster coverage and Fam request for a long time outdoor adventure such as video, often using generators. Re-generating more than 10 kg, the output power of more than 1kW. The fuel cell system that weighs only 6kg (excluding fuel), but only the output power of 100W. Try the system’s NHK broadcasting bureau chief technology center reports ze engineers Tachi said, “To drive the camera, lighting and display package, such as broadcast equipment, the minimum needs of about 500W.” As a result, only this time the fuel cell system for a power LED lights.

In addition, due to the use of the fuel is methanol, is not directly contribute to reduction of  sony a1045 battery. However, if in the future be able to produce energy from renewable bio-ethanol and hydrogen as fuel, is expected to contribute to environmental protection.

Use of LED lighting in order to extend the drive time

LED lighting by NHK andtoshiba PA3399U-1BRSjointly developed the lighting, power consumption is the original tungsten lights about 1 / 3, but with tungsten lights will be the same brightness (Figure 2). In the night outdoors, such as video, can significantly reduce battery dell Latitude D800  consumption. And has confirmed that the studio has also cut lighting power to prevent the rise at room temperature, thereby reducing the effectiveness of air-conditioning power consumption, and so on. In addition, the life expectancy of up to 5 to 60,000 hours, 7 to 8 years do not have to worry about broken. Halogen and the longest life expectancy is only about 300 hours.

Although the power consumption is only 130W, but the projected track to circular 1m, with more than 1600lx the center of brightness, a round projection for the track when the 3m with more than 600lx the center of brightness. The total of 45 equipped with  hp Pavilion ZE2000 RGB three-color LED, the use of irradiation for the 5600 ~ 6000K color temperature of white light. Moreover, the LED lighting reached the TV studio, and other requirements of his color, the average index of 85. At present, there are still difficult to obtain uniform spread of light colors as well as the performance issue. However, NHK said that these issues can be improved through the installation of lights in the pre-filter, and so resolved, the actual use of the basic issues have not
