Description

Smart Safety Guidance Display Apparatus}

The present invention relates to a safety display device, and more particularly, it is installed on the boundary of a danger area such as a coast, a breakwater, a cliff, etc., and when a person approaches, it detects it and emits a character, a pattern, a light, etc. It relates to a smart safety display device that generates lights or warning sounds.

In general, signs indicating dangers when people approach them are installed on breakwaters, port aprons, and coastal areas, but these signs are not attracting people's attention because they only notify the danger by text.

In addition, there is a problem that conventional safety signs often lead to fall accidents due to carelessness because they are not easily visible at night, in heavy fog, or during rainfall.

Accordingly, a safety sign device has been developed that generates its own power by solar light, and emits light informing of danger or generates a warning sound through an LED device or a display device using the generated power.

In order to operate the LED element or the display element of the conventional safety sign, power must be supplied. To this end, a solar charging device is configured in the conventional safety sign.

However, if the solar cell of the solar charging device for power generation is exposed to the outside, the solar cell is damaged even by a small external force or impact, and contaminants are deposited, causing a disruption in power production, making it impossible to operate the LED or display device. There is a possibility of losing its function as a safety sign.

Accordingly, Registration Patent No. 10-1320511 installs a condensing module plate including a solar cell inside the main body, and installs a transparent protective body and a condensing module protection plate to protect the condensing module plate to prevent damage to the solar cell. Possible safety signs are disclosed.

However, the safety sign of the registered patent has a problem in that power production efficiency is low because the light collecting module is installed inside the main body to protect the light collecting module. When the altitude of the sun is low, the amount of sunlight reaching the light collecting module is small.

In addition, conventional safety signs including the above registered patents have low durability and are easily damaged by external impacts, resulting in a small life span.
