Matsushita Electric sky tree lighting to achieve full LED, the development of dedicated purple LED

Recently, Japan TOBU railway, east Wu tower sky tree and Matsushita announced that the scheduled May 22, 2012 opening of the new radio tower "Tokyo sky tree" will all use LED lighting landscape lighting. Installation work was started in mid March 2011. Moreover, in addition to landscape lighting, interior lighting will also promote the use of LED in all of the ordinary tourists access to the full LED lighting". 6 kinds of LED lighting landscape lighting all used Matsushita developed specifically for the sky tree. Lighting equipment totaling 1995 units. Details: at the top of the "gain tower" with white lighting device 60; arranged around the lookout light around a week in about a second ring of the "clock light" 264; as the "golden" Kentucky adjustable lighting lighting equipment 712 Taiwan; set in the intersection of the tower steel "steel cross point" lighting 348 sets of instruments; reminiscent of Sumidagawa shallow blue "essence" lighting equipment 552 Taiwan; performance of Edo purple "elegant" lighting equipment 59 taiwan.

In order to prevent the tower gain lighting apparatus while improving brightness due to leakage caused light pollution, installation of the parabolic surface can make the beam divergence is substantially reduced to twice the "reflector". Each of the cross points of the steel frame using red (R), green (G), blue (B) LED 6. On the other hand, the elegant lighting equipment is through the combination of blue LED and fluorescent materials, developed a special LED.

Control using optical fiber and DMX etc.

The control of the LED lighting is realized by connecting the control system with the devices near the lighting devices. The stage lighting dimming by use of lighting control standards "DMX" and PMW (pulse width modulation).

Matsushita Electric said that through the introduction of these LED lighting appliances, and the company in 2008 to explore the efficiency of the metal halide lamp as the center of the lighting, power consumption can be reduced by 38 ~ 43%.
