The advanced philosophy of the LED tunnel lighting enhance the quality

Tunnel lighting, because its 24 hours of continuous work, and particular attention to safety features, strong demand for new energy-efficient lighting system. Tunnel lighting technology continues to evolve in recent years a variety of new lighting technology, LED, warm white, and discharge lamp, an alternative to traditional high pressure sodium lamps and fluorescent lamps. Among them, the LED has become widely accepted. As energy saving, long life and easy maintenance light source and the system LED use will not only enhance the level of safety, but also can effectively reduce energy consumption and tunnel operating costs. The data show that in 2010 alone, there are 100,000 led spotlights tunnel lights used in tunnel construction, and is believed to have achieved good social and economic effects.

The LED used in tunnel lighting is an integrated project, to consider not only the energy saving effect, brightness, uniformity, the driver s visual experience and other areas need to be taken into account. LED tunnel lighting need the co ncept of forward-looking planning and guidance can be achieved simultaneously enhance quality of lighting and energy saving. Philips years of tunnel lighting technology and R & D experience to support a new point of view, LED tunnel lighting applications based on in-depth understanding of the situation on the roads and tunnels, and guide the direction of development of the industry.

First, to achieve adequate pavement brightness should be the premise of the energy savings. One-sided to mesopic theory emphasis on energy efficient road lighting applications compared to the traditional sodium lamp yellow, white and thus reduce the illumination of the LED lighting applications, may be planted for the safety and security. A significant reduction in the illumination of the LED tunnel lighting, low surface brightness of the lighting effects, poor uniformity, clearly unable to meet the driver s visual needs.

Second, the brightness of the tunnel lighting sta ndard requirements related indicators should be used to measure the effect of LED tunnel lighting in order to achieve harmony average brightness and brightness uniformity of light distribution design. Some led lights for homes tunnel lights in this regard is inadequate - the test to achieve a high uniformity of illumination, but if observed from the driver perspective (60 to 160 meters away) is in between the lamps and the lamps there are are the obvious dark zone of the ground, And this is precisely would have the the driver safe driving of bring the the impact of of can not be ignored; Moreover, these short projection LED will cause the in the the under the per unit length, the lamps and lanterns installation increase in the number of, thereby increasing the the the expenditure of the owners, is not conducive to to play LED energy-saving potential.
