(Light Emitting Diode, 140). The lighting assembly LT_A receives power from the power supply 160 to light the LED 140 .

Accordingly, the present invention maintains the angle at which the LED 140 is designed by mounting and fixing the LED 140 in the light collecting frame 130 installed inclined upward. In addition, since the emitted light is emitted in a condensed state within the condensing frame 130 , directivity is increased and light energy loss is minimized.

More specifically, the lower case 110 is embedded in the installation groove 2 formed in the road 1, such as a driveway, the upper side is open and the receiving space in which the lighting assemblies 120, 130, 140 are installed inside. (see FIG. 9) is provided.

4 , the lower case 110 may be manufactured by molding metal or synthetic resin, and for example, has a cylindrical shape with an open top. In addition, the upper cover 150 is assembled to the mounting base 111 of the upper edge.

The assembly of the lower case 110 and the upper cover 150 is preferably fastened by assembling screws (A-V) as shown as an example, but various other coupling methods such as an interference fit method may be applied.

The circuit board 120 provides illumination toward the road together with the condensing frame 130 and the LED 140 . On the circuit board 120 , conductive lines for supplying control signals or power are formed along a predetermined pattern. has been

The circuit board 120 is installed in the lower case 110 described above, and the module assembling hole 122 is formed through at least one location on the edge portion. The light collecting frame 130 is inserted into the module assembling hole 122 in a sliding manner and assembled with one touch.

As can be seen in more detail through FIG. 5 , the circuit board 120 is configured to include a substrate body 121 , a module assembly hole 122 and an electrode assembly hole 123 formed through the substrate body 121 . can

The substrate body 121 has the above-described circuit pattern formed therein, and can be changed according to the shape of the lower case 110 on which the circuit board 120 is mounted. For example, if the lower case 110 has a cylindrical shape, the circuit board 120 having a disk shape may be used.

As shown in FIG. 6 , the module assembly hole 122 is formed to extend inwardly from one end of the substrate body 121 by a set length so that the light collecting frame 130 is inserted in a sliding manner from the outside to the inside.

The module assembly hole 122 may be formed in several places depending on the number of light collecting frames 130 to be assembled. For example, when the road sign is provided with two light collecting frames 130 (the main light emission directions are in two directions), the module assembly hole 122 is also provided in two places.

In addition, the module assembly hole 122 is cut in a straight line from the outer end of the substrate body 121 toward the inside so that the light collecting frame 130 is slidably inserted, and a pair of binding hooks provided in the light collecting frame 130 ( HK) is formed in two rows to be inserted.

The electrode assembly hole 123 is inserted and coupled to the electrode leg 142 of the LED 140 , and is formed in a portion spaced apart from the inside of the module assembly hole 122 . The formation position of the module assembly hole 122 may be changed in design according to the length of the electrode leg 142 and the size of the light collecting frame 130 .

Accordingly, the electrode leg 142 of the LED 140 protruding through the light collecting tube 131 provided in the light collecting frame 130 is inserted and mounted in the electrode assembly hole 123 . Preferably, the electrode leg 142 inserted into the electrode assembly hole 123 may be electrically connected to a wiring pattern printed on the circuit board 120 through soldering or the like.

At this time, since the LED 140 includes two electrode legs 142 including an anode and a cathode as is known, these electrode legs 142 are inserted into the electrode assembly hole 123, respectively. Two electrode assembly holes 123 are included as possible.

As shown in FIG. 7 , the light collecting frame 130 is a peripheral component for mounting the LED 140 on the circuit board 120 , and the LED 140 is seated and assembled on the light collecting frame 130 and is supported by the light collecting frame. The electrode legs 142 protruding through the 130 are connected and mounted on the circuit board 120 .

To this end, the light collecting frame 130 is made of a non-conductive material, and a plurality of light collecting tubes 131 are arranged inside the light collecting frame 130 . The light collecting tube 131 may be assembled after forming a separate tube, but it is preferable to form a tube-shaped space inside the light collecting frame 130 as shown in the figure.

In addition, the number of light collecting tubes 131 is determined according to the number of LEDs 140 installed in the light collecting frame 130 . In an embodiment, the number of light collecting tubes 131 is the same as the number of LEDs 140 so that one LED 140 is installed for each light collecting tube 131 . Accordingly, when two LEDs 140 are installed in the light collecting frame 130 , two light collecting tubes 131 are provided.

Since the light collecting frame 130 is inserted and assembled into the module assembly hole 122 cut and formed in the circuit board 120 , the LED 140 is installed in the light collecting frame 130 and the circuit board 120 together with the light collecting frame 130 . is mounted on

To this end, the light collecting frame 130 is formed to extend downward from the frame body FB and the frame body FB in which a plurality of light collecting tubes 131 are formed therein to form a module assembly hole of the circuit board 120 ( It includes a binding hook (HK) fastened to 122).

The binding hook (HK) is provided in the shape of a hook that is bent outwardly after extending downward from the bottom of the frame body (FB), and is inserted into the module assembly hole 122 cut in the circuit board 120 . It consists of a pair of elastically pressing (elastic restoration) toward the outside for fixing.

The frame body (FB) has an upper portion open to emit light, a bottom surface through which the electrode legs 142 of the LED 140 inserted and assembled through the upper portion are assembled, and surrounds between the upper portion and the bottom surface. includes the side.

The binding hook HK is formed to extend downward from the side surface of the frame body FB. More precisely, it extends downward from the lower portion of the frame body FB. At this time, the binding hook (HK) allows the open upper portion of the frame body (FB) to be inclined upward toward the road.

In this way, the upper end of the binding hook HK includes a tapered surface inclined at a set angle so that the frame body FB can maintain the upward inclined posture. Accordingly, as the upper tapered surface of the binding hook HK is coupled to the flat side of the frame body FB, the frame body FB is supported to be inclined upward.

In addition, the light collecting frame 130 further includes a support rib (132, rib). The support rib 132 is to maintain the posture of the LED 140 so that the light collecting frame 130 faces the road together with the binding hook (HK), one side is coupled to the bottom surface of the frame body (FB), the other The side surface is supported by being placed on the upper surface of the circuit board 120 .

To this end, the support rib 132 is made of a frame having a substantially triangular shape, and the hypotenuse is coupled (or integrally molded) to the light collecting frame 130 , and the base is placed on the circuit board 120 as the light collecting frame 130 ). The posture of the LED 140 is maintained more firmly.

In addition, the light collecting tube 131 provided in the light collecting frame 130 has an inclined reflective surface RE on its inner peripheral surface so that the light emitted from the LED 140 is reflected toward the light emission port on the front side. The reflective surface RE is formed to be inclined upwardly outward based on the axial center of the hollow part of the light collecting tube 131 .

In particular, the first reflective surface RE1 is spaced apart to have a set interval between the LED 140 and the reflective surface RE, and the diameter of the reflective surface RE increases as it goes toward the front opening (light emission port). ) and the second reflective surface RE2, and has a multi-level structure.

As shown in FIG. 8A , the light collecting tube 131 includes the reflective surface RE together with the reflective layer or separately from the reflective layer. The reflective surface RE is formed in the hollow portion where the LED 140 is installed, that is, the inner circumferential surface of the light collecting tube 131 .

The LED 140 and the reflective surface RE are spaced apart to have a set interval, and may be formed in a multi-stage structure including at least the first reflective surface RE1 and the second reflective surface RE2 . Of course, if necessary, it is possible to provide a structure of three or more steps further than the illustrated two-step structure.

As above, if the reflective surface RE, particularly the multi-stage reflective surfaces RE1 and RE2, is formed on the inner wall surface of the light collecting tube 131 forming the housing of the LED 140, the reflection angle of the light source is increased to reduce the front opening. to guide them towards better emission.

In the case where a reflective surface having a predetermined inclination angle is not formed on the light collecting tube 131 as shown in FIG. 8(b), the light emission efficiency is increased compared to the prior art of FIG. 2, but the reflection angle of the light source is relatively small. This scattering phenomenon increases. Accordingly, it is more preferable to form the reflective surface RE having a multi-stage structure as shown in FIG. 8A .

Returning to FIG. 7 , the light collecting tube 131 is spaced apart from each other with the barrier ribs 133 interposed therebetween in the light collecting frame 130 , and at least a portion of the barrier ribs 133 has heat generated by the LED 140 . It is preferable to include a heat dissipation part 133a cut to be emitted.

The light collecting frame 130 may use a portion of one side of the light collecting tube 131 as the partition wall 133 . To this end, one side of the partition wall 133 and the light collecting tube 131 may be integrally formed, and a portion of the partition wall 133 located inside is cut to protect the LED 140 and the heat dissipation part 133a in an open shape. ) can be formed.

Furthermore, the partition wall 133 between the light collecting tube 131 is composed of two partitions spaced apart from each other, and a cooling hole 134 through which cooling air passes is provided on the bottom surface provided between the two partition walls 133 . It is preferable that it is formed.

Through this, the heat generated by the LED 140 that is receiving power and is emitting light flows into the cooling hole 134 through the heat dissipation unit 133a, and through the cooling hole 134 formed in the bottom surface of the light collecting frame 130 . As heat is emitted, failure of the LED 140 due to heat or shortening of life is prevented even in summer or the like.
