Lenses used for road signs
The present invention provides a lens for a road marker, capable of providing optimal visibility in case of fog and rain. According to an aspect of the present invention, the lens for a road marker includes: an LED emission unit emitting light; an LED control unit linked to the LED emission unit, and controlling brightness and width of light emitted by the LED emission unit; a lens unit positioned in front of the LED emission unit, and enabling the light emitted by the LED emission unit to penetrate the lens unit; and a power unit supplying electric power to the LED emission unit and the LED control unit. The lens unit includes: an incidence surface formed to be concave in an emission direction of the LED emission unit, wherein the light emitted from the LED emission unit reaches the incidence surface; and a radiating surface positioned in front of the incidence surface and formed to be convex in an emission direction of the LED emission unit. The radiating surface radiates the light passing through the incidence surface.
본 발명의 일 측면에 따른 도로 표지병에 사용되는 렌즈는 빛을 표출하는 LED 표출부와, 상기 LED 표출부와 연계되어 상기 LED 표출부를 통해 표출되는 빛의 밝기와 폭을 제어하는 LED 제어부와, 상기 LED 표출부의 전방에 위치하여 상기 LED 표출부에서 표출되는 빛을 투과시키는 렌즈부와, 상기 LED 표출부 및 상기 LED 제어부에 전력을 공급하는 전원부를 구비하고, 상기 렌즈부는 상기 LED 표출부의 표출방향으로 오목하게 형성되어 상기 LED 표출부에서 발광하는 빛이 입사되는 입사면과, 상기 입사면의 전방에 위치하고 상기 LED 표출부의 표출방향으로 볼록하게 형성되어 상기 입사면을 통해 입사된 빛이 출사되는 출사면을 구비할 수 있다.
