However, Shen Yongjia had a different opinion. "Based on its performance, luminescent sheets powder luminous at night only last about four to five hours." Shen Yongjia said, from the continuous emission time, it does not Photoluminescent Pebble guarantee a night lighting.
In addition, he said, adding a luminous pink road signs only a faint green, can not achieve adequate lighting effect. "This suit is not installed street lights in the field road use, traffic can be set to identify the scope, not to put the car into the ditch."
also pointed out that luminous paint painted road lane for the region, street lighting between the lane marking can be covered, the use of light-emitting powder coating can not.
At the same time, cost and stability of the luminous road has also been Luminous sheet questioned scholars.
The key element of long afterglow luminescent powder is rare." Shen Yongjia said before the rare earth prices, the domestic price of 1 kg flour is about 1,000 to 2,000 yuan, and now the price should be higher.
Efficiency luminous pink haze on cloudy days to absorb energy and how high? Absorption efficiency is not high enough in the circumstances, how to ensure continuous light at night?" Experts believe that the luminescence on the road should be photoluminescent pigment suppliers further stability and luminous efficiency research and planning.
