Light-emitting diode (LED) indicating lamp used for road surface directing

Abstract

Provided is a light-emitting diode (LED) indicating lamp used for road surface directing. The LED indicating lamp comprises a stone panel and an indicating signal lamp box formed by a toughened glass arrow, an LED lamp panel shaped like an arrow and a bottom box shaped like an arrow. The upper end of the bottom box shaped like the arrow is a cavity opening, the lamp panel shaped like the arrow is mounted inside the bottom box shaped like the arrow ,the toughened glass arrow is fixedly connected at the upper end of the bottom box shaped like the arrow, an external connection cable of the LED lamp panel extends out of the bottom box shaped like the arrow, a hollow through hole shaped like an arrow is formed in the stone panel, the indicating signal lamp box is embedded and fixed in the through hole shaped like the arrow in the stone panel, and the upper end face of the toughened glass arrow is parallel with the upper end surface of the stone panel. The LED indicating lamp not only provides striking indication, directing and guidance but also is energy-saving and environment-friendly, can be arranged on the ground, and has the advantage of long service life.

Description

technical field [0001] The invention relates to a direction indicating device, in particular to an LED indicator light pointing to a road surface. Background technique [0002] At present, in the guidance of streets, communities and rail transit platforms, signs or arrows drawn with paint are generally used as indicators to indicate the walking direction for people who are not familiar with the road. Since such signs usually do not emit light, they can still be seen in a strong light environment, but in a weak light environment, such as underground passages, rail transit platform passages, large venue passages, shopping mall passages, etc. In an environment with a large flow of people, the conspicuousness of such signs is significantly reduced, resulting in pedestrians unable to distinguish the walking direction, and staying in search of the direction causes congestion. There are also fluorescent paints on the ground to draw indicating arrows to point to, but due to the ste...

AI Technical Summary

Problems solved by technology

Since such signs usually do not emit light, they can still be seen in strong light environments, but in weak light environments, such as underground passages, rail transit platform passages, large venue passages, shopping mall passages, etc. In an environment with a large flow of people, the eye-catching degree of such signs is significantly reduced, causing pedestrians to be unable to distinguish the direction of walking, and stranded due to looking for directions to cause congestion

There are also fluorescent paints used to draw indicator arrows on the ground, but the fluorescent paint will be worn away due to the trampling of passers-by, causing the indicator signs to disappear.

There is also a form of light box indication, incandescent lamps or fluorescent lamps are installed in the transparent box that marks the direction of the road, so that pedestrians can also see the light box in a dim environment. It is installed on the ground, but under the strong light stimulation of incandescent lamps or fluorescent lamps in the box, it will cause strong light pollution, especially this kind of light box using incandescent lamps or fluorescent lamps, because the service life of incandescent lamps or fluorescent lamps is short, often broken, It leads to high cost of use. Once it is broken, it cannot be replaced in time, and the light box indicator is useless and cannot play an indicating role

Moreover, the power consumption of incandescent lamps and fluorescent lamps is relatively large. Turning on day and night will cause a lot of waste of energy, which is not conducive to energy saving.
