Description

[Technical field]

[0001] The present invention relates to a delineator, and more particularly to a delineator that can increase visibility by making the light emitted from the delineator brighter. [Background technology]

[0002] Delineators, which are generally installed around roads, are used to ensure safe driving by scattering light from the vehicle's headlights on the front surface and projecting it outside.

[0003] Conventional delineators had a very simple structure, and only had an indirect reflection function that primarily diffusely reflected the light entering from the vehicle's headlights at the front and projected it to the outside. However, when the reflection efficiency decreased in fog or rain, there was a problem that visibility was significantly reduced.

[0004] To solve these problems, in recent years, delineators have begun to be equipped with lighting devices such as LEDs in addition to conventional reflectors, making them more visible even in foggy or rainy weather.

[0005] However, conventional delineators simply reflected the light emitted from the LED forward, which limited the ability to increase the visibility of the delineator. [Prior art documents] [Patent documents]

[0007] The present invention is intended to solve the above-mentioned problems, and aims to provide a delineator that can transmit the light emitted from the LED attached to the delineator farther, making it brighter and increasing visibility. [Means for solving the problem]

[0008] In order to achieve the above object, the delineator of the present invention comprises a main body having one surface formed in the front and another surface formed in the rear; A number of first LEDs arranged along a periphery from one surface of the body; a transmission lens portion covering all of the first LEDs, the transmission lens portion having a rear surface facing the first LEDs, on which a number of concentric protrusions are continuously formed with each of the first LEDs as a center, and a through hole formed in the center; a reflective lens portion disposed in the through hole for reflecting light incident from the front of the outside; and the light emitted from the first LED is refracted by the protrusion of the transparent lens portion and is irradiated forward in parallel.

[0009] The illumination device further includes a reflective member disposed around the first LED and reflecting light emitted from the first LED to the transmissive lens portion, the light emitted from the first LED being refracted by a protrusion of the transmissive lens portion and irradiated forward to form relatively bright and dark sections, and the reflective member reflects the light emitted from the first LED to a portion of the rear surface of the transmissive lens portion that forms the dark section.

[0010] The reflective member is formed to be inclined downward toward the center of the first LED.

[0011] The reflective member has a number of third reflective protrusions formed in succession in a concentric circle centered on the first LED, and the third reflective protrusions form a concentric circle with the protrusion of the transmissive lens portion, and the light emitted from the first LED is reflected by the third reflective protrusions and irradiated to a portion of the rear surface of the transmissive lens portion that forms the dark section.

[0012] The reflective member is disposed between a plurality of first LEDs spaced apart from one another, and both sides of the reflective member are formed to be inclined downward in opposite directions.

[0013] A coupling protrusion is formed at the center of the rear surface of the reflecting member, and the coupling protrusion protrudes further rearward than both sides of the reflecting member, and the coupling protrusion penetrates the body and is detachably coupled to the body.

[0014] The reflective lens unit further includes a second LED disposed at the center of one surface of the main body, and the reflective lens unit is composed of a first reflecting unit that is disposed around the reflective lens unit and retroreflects light incident from the front outside, and a semi-transparent second reflecting unit that is disposed at the center of the reflective lens unit and faces while covering the second LED, and reflects a portion of the light incident from the front outside while transmitting the light emitted from the second LED to the front outside.

[0015] A number of first reflective protrusions having pointed ends are formed in succession on the rear surface of the first reflective portion, and second reflective protrusions are formed in succession on the rear surface of the second reflective portion by cutting the pointed ends of the first reflective protrusions flat. The second reflective protrusions with flat ends transmit light emitted from the second LED forward. Effect of the Invention

[0016] The delineator of the present invention as described above has the following effects.

[0017] According to the present invention, the protrusion formed on the transmissive lens portion can transmit the light emitted from the first LED further, making it brighter and increasing visibility.

[0018] Furthermore, the present invention allows the driver to more clearly see the delineator even in weather or environments (fog, rain, etc.) in which reflection efficiency is reduced by reflecting light incident from the outside forward and actively dispersing the light forward through the first LED and the second LED.

[0019] In particular, since the first LED radiates light around the reflective lens portion and the second LED radiates light at the center of the reflective lens portion, the driver can more clearly check the position and pattern of the delineator. The first reflective portion of the reflective lens portion retroreflects light, and the second reflective portion smoothly radiates the light radiated from the second LED forward through partial reflection and partial transmission, thereby further improving visibility.

[0020] In addition, by using the reflective member to brighten the dark areas formed by the light refracted by the transmitting lens section and then irradiated forward, the brightness of the light irradiated forward through the transmitting lens section can be made more uniform regardless of position, and the dark areas can be brightened, thereby improving the visibility of the delineator.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] As shown in Figures 1 to 6, the delineator of the present invention includes a main body (10), a first LED (21), a second LED (22), a transmissive lens portion (30), a reflective lens portion (40), a reflective member (50), etc.

[0023] The body (10) has one surface formed at the front and the other surface formed at the rear.

[0024] A circuit board, a battery, etc. are arranged inside the body (10), and a bracket is attached to the rear surface of the body (10) so that the body (10) can be connected to the outside.

[0025] A reflector is formed on one side of the body (10) to reflect light emitted from the first LED (21) and the second LED (22) forward, as described below, and also to reflect light incident from the outside.

[0026] As shown in Figures 2 and 4, a first circular mounting groove (11) is formed along the periphery of one surface of the main body (10), and a second mounting groove (12) is formed in the center of the one surface.

[0027] The first LEDs (21) are a plurality of LEDs arranged spaced apart from one another along the periphery of one surface of the body (10).

[0028] More specifically, as shown in FIG. 4, the first LED (21) is mounted in the first mounting groove (11) formed in a circular shape on one surface of the body (10).

[0029] The second LED (22) is disposed at the center of one surface of the body (10).

[0030] More specifically, as shown in FIG. 4, the second LED (22) is mounted in the second mounting groove (12) formed in the center of one surface of the body (10).

[0031] The first LED (21) and the second LED (22) are connected to a substrate built into the main body (10).

[0032] The light emitted from the first LED (21) and the second LED (22) is irradiated forward, and a part of the light is reflected by a reflector formed on one surface of the body (10) and then irradiated forward.

[0033] The transmitting lens portion (30) and the reflecting lens portion (40) cover one surface of the main body (10).

[0034] The transmission lens portion (30) is coupled to one surface of the body (10) while covering all of the first LEDs (21).

[0035] A solar cell (31) is installed on the upper part of the transparent lens portion (30), and the solar cell (31) is connected to a built-in battery of the main body (10) so that electricity produced by the solar cell (31) can be charged to the battery.

[0036] A through hole (32) penetrating from front to rear is formed in the center of the transmission lens portion (30).

[0037] Furthermore, on the rear surface of the transparent lens portion (30), i.e., the surface facing the first LEDs (21), as shown in Figures 3 and 5, a number of concentric protrusions (33) are formed continuously around each of the first LEDs (21).

[0038] The projections (33) enable the transmission lens part (30) to embody a function like a Fresnel lens.

[0039] In other words, the light emitted from the first LED (21) is refracted by the protrusion (33) of the transparent lens portion (30) and is irradiated forward in parallel, so that the light can be irradiated in parallel even farther, and the driver can recognize the delineator through the light from the first LED (21) even from a long distance.

[0040] Since the first LED (21) is formed along the periphery of one surface of the main body (10), a large number of the protrusions (33) are arranged around the through hole (32) of the transparent lens portion (30), and the first LED (21) is arranged at the center of the large number of the protrusions (33) formed in a concentric circle.

[0041] The reflective lens portion (40) is for reflecting light incident from the front outside, is disposed in the through hole (32), and covers the portion where the second LED (22) is attached.

[0042] The reflective lens portion (40), as shown in Figs. 3 and 6, is composed of a first reflective portion (41) and a second reflective portion (45).

[0043] The first reflecting portion (41) is disposed around the reflecting lens portion (40).

[0044] The first reflecting portion (41) retroreflects light incident from the front outside toward the front.

[0045] The second reflecting portion (45) is disposed at the center of the reflecting lens portion (40) and is disposed so as to face the second LED (22).

[0046] The second reflector (45) has a semi-transmissive property and structure, and as shown in FIG. 7, reflects a portion of the light incident from the front outside while transmitting the light emitted from the second LED (22) to the front outside.

[0047] As shown in FIGS. 6 and 7, a number of first reflecting protrusions 42 each having a pointed end are continuously formed on the rear surface of the first reflecting portion 41. As shown in FIG.

[0048] As shown in Figures 6 and 7, a second reflective protrusion (46) is formed on the rear surface of the second reflective portion (45) by cutting the pointed end of the first reflective protrusion (42) flat.

[0049] As shown in FIG. 7, the second reflective protrusion 46, the end of which is cut flat, transmits the light emitted from the second LED 22 forward.

[0050] More specifically, of the light incident on the transparent lens portion (30) from the outside, the light incident on the first reflecting portion (41) is retroreflected by the first reflecting portion (41) and reflected forward, and the light incident on the second reflecting portion (45) is partially reflected and partially transmitted, and is reflected forward by a reflector arranged around the second LED (22).

[0051] The light emitted from the second LED (22) passes through the second reflecting portion (45) on which the second reflecting protrusion (46) having a flat cut end is formed, and then is irradiated forward.

[0052] As described above, the present invention allows the driver to more clearly see the delineator even in weather or environments (such as fog or rain) in which reflection efficiency is reduced by reflecting light incident from the outside and actively dispersing the light forward through the second LED (22).

[0053] In particular, since the first LED (21) radiates light around the reflective lens portion (40) and the second LED (22) radiates light at the center of the reflective lens portion (40), the driver can more clearly check the position and pattern of the delineator. The first reflective portion (41) of the reflective lens portion (40) retroreflects light, and the second reflective portion (45) can smoothly radiate the light radiated from the second LED (22) forward through partial reflection and partial transmission, thereby further improving visibility.

[0054] As shown in Figures 4 and 9, the reflective member (50) is disposed around the first LED (21) and serves to reflect the light emitted from the first LED (21) to the transmissive lens portion (30).

[0055] The light emitted from the first LED (21) is refracted by the protrusion (33) of the transmission lens portion (30) and is irradiated forward, forming relatively bright and dark sections.

[0056] FIG. 9 illustrates the brightness, i.e., the difference in shading, when there is no light from the reflecting member (50) of the present invention and when light from the reflecting member (50) is added.

[0057] In the absence of the reflective member (50) and the additional light provided by the reflective member (50), the light emitted from the first LED (21) and transmitted through the transmission lens portion (30) would display a large difference in shading between the bright and dark sections.

[0058] The reflecting member (50) reflects the light emitted from the first LED (21) toward a portion of the rear surface of the transmission lens portion (30) that forms the dark section.

[0059] As a result, the dark section formed by the transmissive lens portion (30), i.e., the section where a small amount of light is irradiated forward, can be made brighter by irradiating the dark section with additional light through the reflective member (50).

[0060] That is, as shown in FIG. 9, when light is added by the reflective member (50), the light emitted from the first LED (21) is added to the dark section generated while passing through the transmission lens portion (30), thereby brightening the dark section and reducing the shading difference between the bright and dark sections.

[0061] In this embodiment, the reflecting member (50) is formed so as to be inclined downward toward the center of the first LED (21).

[0062] The reflecting member (50) has a number of third reflecting protrusions (51) continuously formed in a concentric circle shape centered on the first LED (21).

[0063] At this time, the third reflecting protrusion (51) forms the same concentric circle as the protruding portion of the transmitting lens portion (30).

[0064] The light emitted from the first LED (21) is reflected by the third reflective protrusion (51) and irradiated onto the portion of the rear surface of the transmission lens portion (30) that forms the dark section, thereby brightening the dark section.

[0065] The reflective member (50) is disposed between a number of first LEDs (21) spaced apart from each other, and both sides of the reflective member (50) are formed to be inclined downward in opposite directions.

[0066] That is, the reflecting member (50) is disposed so that both sides are inclined downward in both directions in which the first LEDs (21) are disposed.

[0067] Therefore, the light emitted from the adjacent first LEDs (21) is reflected by the reflecting member (50) disposed therebetween, and is irradiated forward.

[0068] A coupling protrusion (52) is formed at the center of the rear surface of the reflecting member (50).

[0069] The coupling protrusions (52) protrude further rearward from both sides of the reflecting member (50).

[0070] The coupling protrusion (52) penetrates the main body (10) and is detachably coupled to the main body (10).

[0071] FIG. 10 shows photographs of the brightness of the delineator when the reflecting member (50) of the present invention is not attached and when the reflecting member (50) is attached.

[0072] In FIG. 10, it can be seen that in the structure in which the reflective member 50 is installed, the dark area is reduced and the brightness of the delineator becomes brighter.

[0073] As described above, by brightening the dark areas formed by the light refracted by the transmitting lens portion (30) and then irradiated forward with the additional light reflected by the reflecting member (50), the brightness of the light irradiated forward through the transmitting lens portion (30) can be made more uniform in a bright state regardless of position, and the dark areas can be brightened, thereby improving the visibility of the delineator.

[0074] The delineator of the present invention is not limited to the above-described embodiment, and may be modified in various ways within the scope of the technical concept of the present invention. [Explanation of symbols]
