Hereinafter, a detailed configuration of the present invention will be described with reference to the accompanying drawings.

Safety induction light using the light emitting diode according to the present invention (hereinafter referred to as "safe induction light"), as shown in Figures 2 and 9, basically the body 1000, the upper case 100, the lower case 200 , The light emitting diode 118, the circuit board 120, the connection member 210, the insulator 220, the regulator 400, and the heat sink 300.

As shown in Figures 2 to 4, wherein the body 1000 of the safety induction lamp according to the present invention is made by the combination of the upper case 100 and the lower case 200, the body 1000 is a core drill It is embedded in the groove formed in the road by.

When the main body 1000 is embedded in the groove of the road, only the upper surface 100a of the upper case 100 is exposed, and all the remaining parts are embedded in the groove of the road and are in an unexposed state, and the main body 1000 The concrete epoxy is filled between the main body 1000 and the groove of the road in a state where the groove is inserted into the groove, and the main body 1000 is fixed to the groove of the road, and the main body 1000 is formed by the concrete epoxy. Basically, the effect is to seal.

As shown in FIG. 9, and in the light emitting diode 118 according to the present invention, when a current passes through a conductive material attached to an electrode above and below, a positive charge particle called electrons and holes is combined at the center of the electrode to emit light photons. It is a structure that emits. Depending on the nature of the material, the color of light is used by known means.

2, 3, 4, 7 and 9, the upper case 100 of the main body 1000 has an upper surface 100a forming a portion to which light of the light emitting diode 118 is irradiated. Basically, the upper part is hermetically sealed to form an upper surface 100a, the bottom surface portion 100b is opened, and an insertion portion 140 for insertion into a step of the lower case to be described later is formed at the edge of the bottom surface portion 100b. First and second accommodation spaces 116a and b are formed in the bottom portion 100b to which the light emitting diode 118 described later is mounted.

The first and second accommodation spaces 116a and b are separated by the partition wall 115 to have two receiving spaces of their own.

As shown in FIGS. 2, 3, 4, 7 and 9, first, second and third protrusions 102, 104, and 106 are formed on the front and left and right sides of the upper surface 100a of the upper case 100 exposed to the road surface. The bottom surface 108 is formed at the center of the upper case 100 to be flat.

In addition, between the first and second protrusions 102 and 104 and between the second and third protrusions 102 and 106, water or debris accumulated on the bottom surface 108 may move to the outside of the upper case 100, respectively. A groove 114 is formed to be recessed in the front side so as to extend from the surface 108.

Accordingly, the upper surface 100a of the upper case 100 has a shape in which the groove 114 and the bottom surface 108 are formed in a “Y” shape between the first, second, and third protrusions 102, 104, and 106.

Here, the bottom surface 108 has one or more through holes 108b formed therein, and heat generated from the regulator 400 installed in contact with the bottom surface of the upper case 100, which will be described later, is formed on the bottom surface of the upper portion of the upper case 100 ( 108) to enable delivery.

In addition, the bottom surface 108 itself has a kind of settled groove 108b corresponding to the thickness and surface area of the heat sink 300 so that the heat sink 300 to be described later can be inserted and mounted.

As shown in FIG. 4, at least one light emitting display window 110 may be formed on the first protrusion formed on the front side of the first surface of the first protrusion.

The light emitting display window 110 communicates with the accommodation space 116 of the bottom portion 100b of the upper case 100. The accommodation space 116 includes a light emitting diode 118 and the light emitting diode 118. The circuit board 120 includes an electronic circuit for controlling and a lead wire 122 connecting the circuit board 120 and an external power supply line 129 to each other.

Here, the accommodation space 116 is provided with a deflection means 119 for polarizing the light of the light emitting diode 118 and transmitting it to the light emitting display window.

This is because the light emitting diode 118 irradiates the light almost parallel to the road surface through the light emitting display window 110 so that the vehicle driver can easily recognize the light. However, the light emitting display window 110 has the first protrusion 102 and the bottom surface. Since the 108 is formed on the adjacent oblique surface 109, the installation space of the light emitting diode 118 is limited.

In order to improve this, the light emitted from the light emitting diode 118 is collected in a separate reflector, and the light is irradiated to the light emitting display window 110 by being irradiated to the prism so as to be deflected.

Of course, the light emitting display window 110 is implemented as a transparent or semi-transparent window and serves as a sealed role so that the light emitting diode window 118, the circuit board 120, and the lead wire 122 mounted inside the light emitting display window 110 and the receiving space 116. Protect your back from the outside.

Since the deflecting means 119 such as the prism is already known, a detailed description thereof will be omitted.

As illustrated in FIG. 7 and 9, the first accommodating space 116a of the upper case 100 in which the light emitting diode 118, the electronic circuit, and the lead wire 122 for connecting it to the outside is mounted is an epoxy resin. The molding process is performed in order to protect the light emitting diode 118, the electronic circuit, and the lead wire 122 from external impact, high temperature, low temperature, and humidity.

As shown in FIG. 11, the safety induction lamp using the light emitting diode 118 of the present invention is installed mainly buried in the shoulder of the road, and when a bulldozer, a fork lane, etc. pass, the case of stepping on the safety induction light occurs. do.

Accordingly, the upper portion of the safety induction lamp may be crushed or the light emitting display window 110 may be damaged by the load of the vehicles.

As shown in FIGS. 2 and 3, the first, second, and third protrusions 102, 104, and 106 of the upper case 100 are formed with an inclined portion 112 inclined downward in the circumferential direction to allow traffic to and from the vehicle. It is.

That is, a flat surface of a predetermined area is formed inside the first, second and third protrusions 102, 104 and 106 of the upper case 100, and is inclined downward in the circumferential direction from the outer end of the flat surface. In this way, the vehicle is allowed to come and go without damaging the device by the inclined portion (112).

Here, as an embodiment of the present invention, the light emitting display window 110 of the first protrusion 102 is not one as shown in Fig. 8, but as shown in Figs. A plurality of auxiliary protrusions 107 are further formed between the 104 and 106.

The auxiliary protrusion 107 is formed vertically between the light emitting display windows 110 to induce light irradiated from the light emitting display windows 110, and the bottom surface 108 of the upper surface 100a of the upper case 100. To prevent wounds.

Of course, the auxiliary protrusion 107, as well as the first, second, third protrusions (102, 104, 106) is formed of the inclined portion for coming and going of course.

In the above embodiment, the number of heat sinks 300 is also increased by the auxiliary protrusion 107.

As shown in Figures 2 and 3, where winter snow (snow) is accumulated on the upper surface (100a) of the upper case 100, the safety induction lamp of the present invention is difficult to operate normally. That is, when snow accumulates on the light emitting display window 110 on the upper surface 100a of the upper case 100, the light emitted from the light emitting display window 110 may not be properly irradiated by the snow, and the vehicle driver may recognize this correctly. It is hard to do.

Accordingly, the regulator 400 and the heat sink 300 are installed to heat the upper surface 100a of the upper case 100.

As illustrated in FIG. 7, the regulator 400 is connected to a circuit board (not shown) mounted on the first accommodating space 116a of the upper case 100 through a lead wire 122 to receive power. (Power supply line-circuit board-lead wire-regulator-lead wire-circuit board), a device that converts the power supply suitable for light emitting diodes, which regulator 400 normally converts the input power of 24V to 12V which is the driving power of the light emitting diodes. Heat generated at the time is installed for use as heating heat of the upper surface (100a) of the upper case (100).

The installation position of the regulator 400 is preferably the bottom surface of the upper case 100, as described above is installed on the bottom surface (100b) of the position corresponding to the through hole 108b of the upper case 100, The coupling hole 402 is formed at one side of the regulator 400 is made of a structure that can be inserted into the fixing member 500 such as a bolt.

Here, the lead wire 122 connecting the regulator 400 and the circuit board 120 molded in the first accommodation space 116a is connected to the circuit of the first accommodation space 116a through the partition wall 115 from the regulator 400. It may be buried by a mounting groove (not shown) connecting to the substrate.

This inserts the lead wires 122 of the circuit board and the regulator 400 into the seating 108f, thereby enabling electrical conduction between the circuit board and the regulator 400 as well as providing the lead wires 122 exposed to the outside. It is to prevent damage and connection failure by being buried.

Accordingly, when power is supplied to the circuit board, power is supplied to the regulator 400 mounted on the bottom surface of the upper case through a lead wire, so that the heat generated when the regulator 400 is converted into a power suitable for a light emitting diode is provided. It is possible to move in the direction of the upper surface (100a) of the upper case 100 through the through hole (108b), can transfer heat to the heat sink 300 mounted on the upper surface (100a) of the upper case (100). It is to be.

Herein, the heat dissipation plate 300 mounted on the upper surface 100a of the upper case 100 is made of a metal having good thermal conductivity of a panel shape, as shown in FIGS. 5 and 6, preferably stainless steel or Made of copper.

As shown in FIG. 5, the upper surface of the heat sink 300 is firmly formed, and as shown in FIG. 6, an insertion part 310 is formed in the bottom surface thereof so as to be inserted into a through hole formed in the bottom surface of the upper case.

Female inserting portion 310b is formed in the inserting portion 310 so that the inserting portion 310 is the bottom of the upper case when the bottom surface of the heat sink 300 is placed on the bottom surface 108 of the upper case 100. It is inserted into the through hole 108b of the surface.

Here, the regulator 400 refers to all known transformation means for converting a normal input voltage into a constant constant voltage, and may use any device that generates heat during transformation, and is fixed to one side of the regulator 400. The male screw portion of the member 500 may be inserted and inserted into the female screw portion 310b of the insertion portion 310 of the heat sink 300 via the through hole 108b of the bottom surface 100b of the upper case 100. The defect hole 402 is formed so that it may become.

Accordingly, the female member 310b of the insertion portion 310 of the heat sink 300 inserted into the through hole 108b of the upper case 100 and the fixing member 500 inserted into the coupling hole 402 of the regulator 400. Heat sink 300, the upper case 100 and the regulator 400 is fixed to each other by screwing the male screw portion of each other and is made to conduct heat.

When snow falls in the winter in the above structure and the snow is accumulated on the surface of the upper case 100, the heat generated from the regulator 400, which is always operated for power supply through the transformation to the light emitting diode, is a through hole. By moving to the upper surface (100a) of the upper case 100, the upper surface of the upper case is always kept above a certain temperature by the heat sink by heating the heat sink is to prevent the snow from freezing. Of course, the heat dissipation amount of the regulator 400 will be sufficiently adjustable by those skilled in the art by controlling the size of the power to be transformed.

In addition, since the regulator 400 is not mounted on the circuit board inside the first accommodating space 116a and is separately separated, the light emitting diode is prevented from being thermally damaged by the heat generated by the regulator 400, thereby preventing the thermal damage of the light emitting diode. It also has the advantage of improving durability.

Looking at the heat transfer relationship between the regulator 400 and the heat sink 300,

Although the through hole 108b is not formed in the bottom surface of the upper case 100a, the entire upper case is heated by the transformation heat generated by the regulator 400 attached to the bottom of the upper case 100a. The heat sink 300 may be configured to be heated.

In another embodiment, even if the insertion portion and the separate fixing member are not formed on the bottom surface of the heat sink 300 in the state where the through hole 108b is formed, heat may move through the through hole.

Accordingly, the upper case 100 and the lower case 200 are combined to assemble the body 1000 integrally. Of course, screw holes 150 are formed in the second and third protrusions 104 and 106 of the upper case 100, and positions corresponding to the screw holes 150 of the second and third protrusions 104 and 106 of the upper case 100.
