Description
Technical field
The present invention relates to a kind of indication light block, especially can initiatively with the indication light block of passive light output.Be widely used in the fields such as the direction board of road signs and markings, vehicles reflecting marking, special operation clothes, fire symbol, railway signs, mining area mark and identified ad.
Background technology
The development history of road sign, the namely development history of reflectorized material.Road signs are generally made up of a few parts such as mark slab, index plane, column, securing member, bases; Reflective membrane Warning Mark is pasted, the direction that it tells people to advance and traffic environment in index plane and front, helps driver to judge road conditions, regulation speed, avoids danger.If traffic sign is the language of road, so the reflectorized material of traffic sign is exactly the sound-producing device of this language, allow the information entrained by traffic sign more clear, convey to road user intuitively.Reflective membrane is as the main material of traffic sign, be invented by Minnesota Mining and Manufacturing Company nineteen thirty-seven, structure is at that time only exposes beaded glass type, within 1948, develops engineering grade reflective membrane,, develop again high-strength reflecting film and Diamond Grade reflective film respectively 1971 and nineteen ninety.
Reflective membrane has beaded glass type and micro-prism type two kinds according to reflective mechanism, and high intensity level, engineering grade, economic reflecting film are beaded glass type, Diamond Grade reflective film be micro-prism type.Its reflex reflection technically development, from remote discovery feature originally, full prism technique not only having achieved remote discovery feature, but also having focused on closely depending on recognizing brightness till now, well should the fast development of right road traffic technology, the new demand changed with each passing day.Above-mentioned traffic sign is passive type ray structure, needs evening strong illumination to reflect output identification, is suitable for the high-grade highway being provided with median glare screen.For the Class I highway without glare screen, province, city, county road or backroad have it not enough.The utilization of dipped headlights is not enough to see mark clearly, and the application of high beam makes the deterioration of safety of highway communication, very easily traffic hazard occurs.As time goes on, luminescence efficiency is more and more lower, and tenure of use was in 3 to 5 years, changes or keep in repair all to add social cost.
After entering 21 century, the Road Safety Status in global range is very sternly completed, and various countries also start to find the countermeasure improving traffic safety performance.By using traffic sign technology, reducing the speed of a motor vehicle, prompting danger, improving the means such as safe sight distance, reducing the generation of traffic hazard.Research display, application traffic sign technology is that cost is minimum, but the most obvious a kind of means of effect.
