Fluorescent powder micro-shell combination for highway or bridge or tunnel traffic safety prompting

Abstract

The invention discloses a fluorescent powder micro-shell combination used for driving safety reminders on roads, bridges or tunnels, which is composed of a hollow micro-shell and fluorescent powder, wherein the hollow micro-shell is made of glass or quartz; the hollow micro-shell is a white transparent sphere , and consists of two hemispheres of the same size, there is a gap between the two hemispheres, and the two hemispheres are connected together through the central axis, and the inner cavities of the two hemispheres are independent of each other; the phosphor is a powder structure, and Phosphor powder of one emission wavelength is hermetically sealed in each hemisphere, and the emission wavelengths of the phosphor powders in the two hemispheres are different. The fluorescent powder of the present invention has a powder structure, and is respectively encapsulated in two hemispheres of a hollow microshell of a microsphere structure. Make phosphors absorb light energy and emit visible light to the greatest extent, and can be used in general urban roads, expressways, bridges and tunnels.

Description

technical field [0001] The invention belongs to the field of traffic, and in particular relates to a fluorescent powder microshell combination used for driving safety reminders on roads, bridges or tunnels. Background technique [0002] With the development of society, traffic is becoming more and more important. However, driving safety is an issue that has to be taken seriously. Every year, traffic accidents across the country lead to a large number of casualties and property losses. At the same time, due to the poor visibility at night, the probability of safety accidents at night is significantly higher than that during the day, and traffic accidents are more likely to occur at night on rainy days. In order to avoid traffic accidents at night, warning lights are usually installed on both sides of roads (especially highways), bridges or tunnels, and these warning lights achieve a prompting effect by actively emitting light. However, the warning lights need to consume elec...

Problems solved by technology

The advantage of this method is that it does not require power consumption, low use and maintenance costs, the emitted light is visible light, and the cost is lower than that of warning lights, but because of the wear-resistant layer, the cost is higher than that of plastic tape and reflective markers; the disadvantage is that the wear-resistant layer After being exposed to wind and sun, the wear-resistant layer will age and fall off, which will expose the phosphor coating, and the surface roughness of the phosphor coating is relatively large. After encountering dust deposition, it is easy to greatly affect the light absorption of the phosphor coating. Energy and luminous efficiency; moreover, the phosphor coating will not occur after contact with water or liquid, so it will be completely ineffective

In addition, even if the wear-resistant layer is not worn, the existing phosphor coating is fixedly coated on the guardrail, and only the phosphor on the surface can effectively absorb light energy. Therefore, in order to avoid wasting materials, the phosphor coating can only be compared Thin, and whether it can glow all night is also a big problem; moreover, the visible light emitted by the fixed phosphor coating is also fixed, and the warning effect of showing width is relatively limited. If the visible light emitted is moving, the warning The effect will be better, and it is less likely to cause visual fatigue, and the existing fixed phosphor coating cannot be achieved at all
