Description

LED display module for road and road boundary stone using it}

The present invention relates to a light emitting diode display module for a road and a road boundary stone using the same.

A light emitting diode (LED) generates light by using a light emission phenomenon (also called electric field emission) caused by a combination of electrons and holes generated when a voltage is applied to a semiconductor. The light emitting diode (LED) is smaller in size and has a longer lifetime than a conventional light source. Since electrical energy is directly converted into light energy, it has the advantage of having high energy efficiency and low operating voltage.

Therefore, LEDs having such advantages are used in various fields such as backlights, lighting lamps, and billboards of liquid crystal displays (LCDs), and when LEDs are used, LEDs are usually arranged on the side of a light guide plate or an advertisement display panel. In addition, a supporting member for protecting and fixing the LED was used in combination with a light guide plate or a display panel separately.

However, since a light guide plate, an advertisement board, etc. using a conventional LED arranges the LEDs into a space between the support member and the light guide plate or the display panel, the space between the plate and the support member is kept constant to maintain the installation of the LED. Since the structure must be carefully considered, the design is complicated and the configuration is complicated. In addition, when the portion where the LED is installed is located on the light guide plate or the side of the display panel or located below the LED, the LED may not emit light due to short-circuit or malfunction due to rainwater introduced between the plate and the support member.

On the other hand, in order to facilitate the passage of cars and pedestrians, and to improve aesthetics, various characters and figures are displayed on the roads, and facilities where these figures and characters are displayed are installed. There are road signs indicating lanes, driving directions, intersections, and the like, and warning signs for separating lanes and sidewalks, and warning signs for bicycle lanes.

Among these, the road boundary stone distinguishes between the driveway where the vehicle runs and the sidewalk where people walk, and is also used to distinguish the bicycle-only road normally installed on the sidewalk. It also serves as a protective seat that prevents vehicles driving on the sidewalks from being easily walked by humans due to inadvertent driver's care. do.

Such road boundary stones are usually made of concrete or stone. In the case of concrete boundary stones, cement, sand, gravel, and water are properly mixed at a ratio, and then the mixture is poured into molds, dried, and dried. It is manufactured by demolding and curing, and in the case of stone, it is used to cut to size.

Accordingly, in addition to the role that the road boundary distinguishes between roads and sidewalks and sidewalks and bicycle paths, it can also provide aesthetics and provide information such as displaying a location or providing a direction for a specific place. There is a clear distinction between roads and sidewalks, and sidewalks and bicycle lanes.

In addition, the light emitting diode is installed inside the back of the transparent or translucent plate to not only solve the impact and waterproof problems, but also to protect the light emitting diode more stably from external shock by covering the light emitting diode portion. It is possible to greatly reduce the problem of breakage during use.

In addition, since the LED has a linearity of light, glare may occur when there is no metal mold, that is, when light is directly emitted from the light emitting diode, and the metal mold is blocked, thereby maintaining uniform illumination overall. Done.

In addition, in order to maintain such uniformity, the diffusion groove may be further installed in the front of the LED to improve the uniformity of light.
