The present invention relates to a road guide sign, and in particular, it is possible to easily control the irradiation range of the LED beam to minimize energy consumption while allowing a smooth irradiation to adjacent road guide signs as well as being separated from a short distance. The present invention relates to an LED beam irradiator for a road guide sign and a road guide sign identification device having the same.

In general, road guide signs are installed on the edges of roads, sidewalks, etc., and provide road and area guidance to drivers and pedestrians by displaying the direction and guidance of the vehicle using various types of characters, symbols, and figures, depending on the purpose. Refers to the facility. Since these road signs must be light sources to reflect the light and hang at a certain height on the ground, drivers can check the road signs at night by turning on high beams or approaching them at a slow speed. There was a risk of accidents.

Accordingly, the road guide signs use various lighting lighting devices that illuminate the signs inside or outside by using various light sources such as signs, incandescent lamps, and LED lamps painted with luminous material for easy identification at night.

5 is an external perspective view of the LED beam irradiator according to the present invention, Figure 6 is an exploded perspective view for explaining the configuration of the LED beam irradiator according to the present invention, Figures 7 and 8 are the configuration of the LED beam irradiator according to the present invention This is a partial incision to explain.

As shown, the LED beam irradiator 140 according to the present invention is the LED 142a, the outer casing (141a, 141b, 141c, 141d), the first lens 144a and the second lens 144b, It is made of a spacing control member, the irradiation range of the LED 142a is adjusted by changing the spacing distance of the first lens 144a and the second lens 144b by the spacing control member.

Here, the first lens 144a is installed while wrapping the LED 142a in front of the LED holder 142b on which the LED 142a is mounted. As a result, the irradiation range of the LED 142a is primarily expanded.

In addition, the second lens 144b is fixed to the front cover 141b of the outer casing. As a result, the irradiation range of the LED 142a beam enlarged by the first lens 144a at the position spaced to the front side of the first lens 144a is further expanded. The present invention can rapidly expand the irradiation range of the LED 142a beam by the two lenses 144a and 144b.

The separation adjusting member serves to adjust the separation distance between the first lens 144a and the second lens 144b. To this end, the spacing control member includes an LED housing 143 and an LED housing 143 on which an LED holder 142b equipped with the LED 142a and the first lens 144a is installed and supported at a front end portion thereof, and the LED housing 143. It includes a rotor 144 to move while wrapping from the outside.

Here, the rotor 144 is provided with a guide hole 144a formed in an oblique direction, and correspondingly along the guide hole 144a of the rotor 144 in a protruding form on the outer wall of the LED housing 143. The movable body 143a that moves while being guided is installed. In addition, an outer circumferential surface of the rotor 144 is provided with an annular rotating projection 144c is inserted into the circumferential rotation groove 141a-2 formed on the inner circumferential surface of the body casing 141a. As a result, the rotor 144 smoothly rotates without being separated from the body casing 141a.

In addition, the LED holder 142b installed at the front end of the LED housing 143 has a plate shape surrounding the LED 142a and collects light emitted from the LED 142a through the first lens 144a. Project it.

According to the configuration of the separation control member such that when the rotor 144 is rotated, the moving body 143a moves forward or backward while moving along the guide hole 144a. Accordingly, the LED housing 143 and the first lens 144a mounted thereto move forward or backward. In this case, when the first lens 144a is moved forward, the separation distance from the second lens 144b decreases, and when the first lens 144a moves forward, the separation distance from the second lens 144b increases.

9A and 9B are a series of reference diagrams for explaining the internal retreat operation for adjusting the irradiation range of the LED beam irradiator according to the present invention.

As shown in FIG. 9A, when the first lens 144a is retracted to increase the separation distance between the first lens 144a and the second lens 144b, the LED 142a enlarged with the separation distance through the first lens 144a. When the beam is spread by the second lens 144b once more and the irradiation range is rapidly increased, the intensity of the irradiation is weakened and becomes dark. On the other hand, as shown in FIG. 9B, when the first lens 144a is advanced and the separation distance between the first lens 144a and the second lens 144b is reduced, the LED 142a beams are collected and the irradiation range is reduced. The century gets brighter as it gets stronger.

Therefore, it is possible to adjust the range and brightness to which the LED 142a beam is irradiated according to the surrounding environment. For example, on the day when the fog is heavy or rain or snow, the first lens 144a may be moved forward and adjusted brightly. On a relatively clear day, the first lens 144a may be retracted to weakly adjust the intensity of irradiation. I can do it.

Furthermore, in the beam irradiator 140 according to the present invention, a motor 145 for rotating the rotor 144 is installed at the rear side of the rotor 144. The shaft 145a of the motor 145 is fitted to the shaft fitting portion 144d provided at the rear end of the rotor 144 and coupled thereto. When the motor 145 capable of rotating the rotor 144 is provided as described above, the user can easily adjust the LED 142a irradiation range by driving the motor 145 through an external switch (not shown). do.

On the other hand, the outer casing (141a, 141b, 141c, 141d) is coupled to the front end of the body casing (141a), including the body casing (141a) surrounding the main portion, such as the separation control member of the second lens (144b) A front cover 141b for guiding the LED 142a beam while surrounding the periphery, a motor casing 141c coupled to the rear end of the body casing 141a to surround the motor 145, and the motor casing ( It comprises a rear casing (141d) coupled to the rear end of 141c. These body casings 141a, the front cover 141b, the motor casing 141c, and the rear casing 141d are provided with male threads 141a-1 or female screws and screwed together. In this case, the rear casing 141d serves to surround the case when the rechargeable battery 163 is provided, so that the size of the rear casing 141d may be adjusted according to the volume of the rechargeable battery 163.
