In general, street lights are installed for pedestrians of roads and pedestrians of roads, so that it is possible to eliminate the anxiety of the driver or pedestrian of the vehicle and to prevent accidents.

In recent years, LED street lamps have been used to reduce maintenance costs due to power consumption. In the case of LED street lamps, the power consumption is varied from 10W to 250W, and the manufacture and maintenance of various kinds of street lamps To make it easier, we are manufacturing LED street lamps with various sizes of power consumption by using lighting module for LED street light that integrates heat dissipation, light distribution and waterproof function.

In the case of Korea, the Korea Highway Corporation has introduced standardized modular street lamps based on 25W per unit from 2014, followed by standardization of Seoul street lamps in the same way as Seoul city. In the module heat sinks (heat sinks) The heat transferred through the air layer inside the housing must be radiated through the convection flow, so that the heat is confined in the closed housing and the radiating effect is lowered.

On the other hand, street lamps installed on residential streets or rice paddies and around the fields interfere with people sleeping at night and act as a factor that hinders the growth of crops.

Many reflectors and shading plates have been developed so as to eliminate such obstacles, that is, to make the street lamp shine only a desired path length. However, since the structure is complicated, it has not been actually applied. "Light blinders for streetlight fixtures and streetlight fixtures incorporating them" such as No. 20-0465312 have been developed.

A rear portion of the cutout hole 55 The first reflecting plate 57 protruding in the direction of the lens 37 serves to forwardly reflect the light of the LED irradiated rearward through the lens 37. [

The first reflector 57 may be fixed to the fastening plate 53 so as to be positioned behind the incision hole 55. However, It is preferable to easily fabricate and install a simple structure by integrally forming a rear end of the incisional hole 55 with a portion cut by the fastening plate 53. [

In the present invention, as shown in FIG. 1, 2, or 6 and 7, a second reflector 60 for reflecting the light of the LED which can not be completely reflected through the light shield 50 at a desired angle is additionally provided This can be easily achieved by projecting the second reflector 60 downwardly from the rear of the module cover 20, that is, behind the installation hole 21 located at the rear end.

Here, the second reflector 60 may be integrally formed with the module cover 20, but it may be detachably attached to the module cover 20 if necessary, thereby preventing unnecessary use in a place where it is not needed. It is preferable to be able to easily combine and use them when they are changed to necessary situations with the passage of time.

At this time, the second connector (20) is hinged on one side of the second reflector (60) through a first connector (210) coupled to the module cover (20) The second reflector 60 may be coupled to the second reflector 60 through a coupling groove (not shown) to which the second connector 220 is coupled, 62 are formed on the inner circumference of the coupling groove 62. A groove 63 for adjusting the installation angle of the second reflection plate 220 is formed on the inner circumference of the coupling groove 62 at regular intervals.

The second connector 220 includes the bracket 221, the fixing shaft 223, the fixing protrusion 225, the elastic body 227, and the detachment stopper 229, 60, and the angle of installation can be easily changed, and this configuration will be described in more detail below.

First, the bracket 221 is fixedly coupled to the lower side of the module cover 20 through a normal bolt connection or the like for the connection of the second reflection plate 60.

The fixing shaft 223 is configured to engage the fixing protrusion 225 with the elastic body 227 and the detachment stopper 229 to detach and couple the second reflector 60. The fixing bracket 221, It is preferable to form a polygonal shape rather than a circular shape in order to prevent the rotation of the coupled fixing protrusions 225. In addition, a female screw 223a for engagement of the detachment prevention cap 229 do.

The fixed protrusion 225 is moved in the direction of the second reflector 60 by the elastic force of the elastic body 227 while being slidably engaged with the fixed shaft 223, A protrusion 225a fitted to the groove portion 63 of the second reflection plate 60 is formed on the outer circumference at equal intervals so that the angle of the body 225b ).

In addition, a fitting hole 225c formed in the shape of a polygonal groove is formed in the body 225b so as to slide with the fixed shaft 223, so that the fixed projection 225 can be fixed Only the longitudinal direction of the shaft 223 is slid.

The first and second space portions 225f and 225g are formed in the body 225b so that first and second protrusions 225d and 225e may be formed on both sides of the fitting hole 225c The body 225b of the fixing protrusion 225 may further include a handle for allowing the operator to more easily operate the fixing protrusion 225, although not shown in the drawings.

The elastic member 227 is installed in the first space portion 225f so as to elastically act between the bracket 221 and the first protrusion 225d of the fixed protrusion 225 in a state sandwiched between the fixed shaft 223 And acts to elastically couple the engaging groove 62 of the second reflector 60 to the fixing protrusion 225 by applying an elastic force to the first protrusion 225d.

The detent stopper 229 is configured to prevent detachment of the fixing protrusion 225 which is coupled to the fixing shaft 223 and is elastically acting by the elastic body 227, And a head 229b integrally formed with the male screw 229a and disposed in the second space 225g of the fixing protrusion 225. The second reflector The second jaws 225e of the fixing protrusions 225 that are moved by the elastic force when the first and second fixing protrusions are not installed are caught by the head 229b.

The operation according to the above-described configuration will be described as follows.

In the present invention, the heat sink 35 is attached to the LED module 30, and the LED module 30 is heated by the lamp module 30, Most of the heat of the heat sink 35 is transferred to the housing 10 through the heat pipe 40 because the heat pipe 40 connected to the heat pipe 40 through the heat pipe 40 directly contacts the inner surface of the housing 10 The action is rapidly released to the outside.

Accordingly, since the heat of the heat sink 35 is hardly left in the housing 10, the interior of the housing 10 can be maintained in a cool state, so that the LED, which is vulnerable to heat, can be safely protected, It is advantageous in that it can be improved.

In the present invention, since the first reflector 57 formed on the light shield 50 is provided behind each lens 37, the light of the LED illuminating the periphery is diffused through the lens 37, It is possible to minimize the backward irradiation of light, thereby preventing damages of houses and crops located behind the streetlight device, and preventing light loss through reflection of light.

In addition, the present invention can easily detach and attach the second reflector 60 through the operation of the fixing protrusion 225 formed in the second connector 220, Since the groove portion 63 and the protruding portion 225a can be aligned by fitting the fixing protrusion 225 into the coupling groove 62 of the second reflection plate 60 in the adjusted state, So that it can be easily fixed and installed.

Accordingly, it is possible to easily adjust the diffusion range of the LED light irradiated in the rear and downward directions of the streetlight device through the lens 37, and also to adjust the direction in which the light is reflected, And it has an advantage that a desired portion can be brighterly illuminated through a high concentration of light.
