Description

Column cap

Technical Field

The utility model relates to the technical field of road illumination, in particular to a column cap.

Background

The column cap is a traffic safety facility with wide application, is arranged on the upright column, is arranged along the two side edges of the road or the middle separation line of the road, is used for indicating the advancing direction and the boundary of the road, and reminds drivers and pedestrians of paying attention to traffic safety through the retroreflection performance or the active flashing function.

The caps mainly used in the market at present are divided into three categories;

the first is the most common retroreflective caps, which are structured with one or two retroreflective sheeting. The light irradiates the reflective sheet to realize safe driving reminding of a driver, and the reflective sheet is the most widely used cap on the road surface at present, however, the cap can reflect light only by means of vehicle irradiation, and has poor reflective effect in severe environments such as rainy and foggy days and continuous sharp turning road sections, and meanwhile, the reflective form is single, so that the use function and effect of the cap are greatly reduced in practical road condition application.

The second type of column cap is a photoelectric column cap, the column cap realizes active light emitting of LEDs through a power supply control circuit, and the structure is that a plurality of light emitting LEDs are arranged in a transparent column cap, and drivers and pedestrians are reminded of paying attention to safety through active flashing light emission.

The latest column cap, namely the third column cap, is a self-luminous column cap, the manufacturing principle of the column cap is that a shell is made of transparent materials, then a space is reserved on the inner plane of the shell for encapsulating the self-luminous materials, and the self-luminous materials store energy in the daytime, so that the self-luminous materials maintain a certain brightness effect. The self-luminous materials in the market at present mainly comprise green fluorescent materials. The self-luminous material can maintain a certain brightness effect after being excited at night, so that the cap is popular on park landscape pavement. However, the cap can work by being fully excited by the energy storage of the self-luminous material, the energy storage time of the self-luminous material is very short, and according to industry data, the brightness of the self-luminous material is reduced to about 200mcd from the original value of 1500mcd only after 10 minutes, and the brightness of the self-luminous material is about 75mcd after 1 hour, so that the cap has a real effect of only dimly giving a light and dark feeling, and is not suitable for being used on complex roads (such as mountain roads or highways) in practice. Therefore, the large-area popularization and application of the column cap are limited. Meanwhile, the column cap is arranged on the column without a lamplight diffusion area, so that the luminous part at the top of the column cap can not be seen basically from a distance, the area of the reflecting sheet on the column cap is small, the installation height is high, and the reflecting sheet basically does not play a role in reflection. Therefore, the practical use effect is very poor.

Therefore, the existing column caps are single in light reflection or light emission mode, low in self-luminous brightness value, single in light emission color, uneven and not soft in light, high in power consumption, short in continuous working time, unobvious in outline display of the existing column caps, unobtrusive and the like. These problems result in a significant safety hazard to the cap, which reduces the useful life.
