Here, the pair of terminal lead-out portions 131 and 132 are tightly fixed to the support portion 121 and the pair of light guide portions 122 and 123.

Therefore, the reflection member 120 is formed by the groove in which the LED substrate 110 is built and the opening (opening) in which the light emitted from the plurality of LEDs 111 is emitted due to the coupling relationship between the support portion 121 and the pair of light guide portions 122, The bottom surface of the groove corresponds to the support portion 121 and the side wall of the groove corresponds to the pair of light guide portions 122 and 123. The support portion 121, which is the bottom surface of the groove, 110 are mounted.

Each of the pair of terminal lead portions 131 and 132 includes metal rods 131b and 132b electrically connected to the LED substrate 110 by a conductive member including a wire 125; And insulating members 131a and 132a in the form of a rectangular bar that protrude at least one ends of the metal rods 131b and 132b and surround the metal rods 131b and 132b and are inserted and fixed in the trench grooves of the reflection member. At this time, the insulating members 131a and 132a can protrude both ends of the metal rods 131b and 132b as shown in FIG.

Each of the metal rods 131b and 132b is electrically connected to the LED substrate 110 by a conductive member and the region where the metal rods 131b and 132b and the conductive member are connected is surrounded by the insulating members 131a and 132a In this case, it is possible to prevent each of the metal rods 131b and 132b from being separated from the conductive member.

One end of each of the metal rods 131b and 132b protrudes from the insulating members 131a and 132a to facilitate connection with an external power source.

The insulating members 131a and 132a may be formed by molding resin encapsulating the metal rods 131b and 132b and the molding resin may surround the connection regions of the metal rods 131b and 132b and the conductive member, Can be prevented from being released.

2, the light emitted from the plurality of LEDs 111 mounted on the LED substrate 110 is reflected by the pair of light guide parts 122 and 123 of the reflection member 120, And is directly emitted to the outside through the open area without being reflected by the pair of light guide parts 122 and 123 of the reflection member 120. [

Accordingly, the side light distribution curve A1 and the top light distribution curve A2 of FIG. 3 show the light distribution characteristics of light emitted from the luminaire without being dispersed, and the luminaire of the present invention can illuminate a specific area It is.

As described above, the luminaire of the present invention is advantageous in that it can be optimally disposed between a plurality of LEDs 111 and a pair of light guide portions 122 and 123, and illuminated by highlighting a specific region.

4, a distance d1 from an optical axis P of a plurality of LEDs 111 mounted on an LED substrate 110 to a light guide portion 123 is divided into a plurality of To the edge of the light exit surface 112 of the LED 111 of the light emitting surface 111 is 3 to 4 times the distance d2. Here, the relation between d1 and d2 is that the light emitted from the plurality of LEDs 111 is guided by the light guide part 123 to suppress the light dispersion and collect the light to be emitted outside the luminaire, Thereby enabling illumination that can highlight a specific area. Here, d1 is preferably 3.5 times d2.

FIG. 5 is a cross-sectional view taken along line A-A 'of FIG. 1 for explaining a lamp according to the first embodiment of the present invention, and FIG. 6 is a diagram illustrating a light distribution distribution of a lamp according to the first embodiment of the present invention.

5, a lamp according to the first embodiment of the present invention includes a pair of light guide portions 122 and 123 each having a length of one light guide 123 longer than that of the other light guide 122 will be.

In other words, the lamp according to the first embodiment has a structure in which the length of one light guide 123 is longer than the length of the other light guide 122, and a path that is emitted from the plurality of LEDs 111 and travels to the left side of the optical axis May be reflected in the right direction from the long light guide 122 to change the traveling path and illuminate the light.

Therefore, like the side light distribution curve B1 and the top surface light distribution curve B2 in Fig. 6, the light emitted from the luminaire of the first embodiment exhibits light distribution characteristics concentrated in the right direction of the optical axis.

Therefore, according to the present invention, it is possible to implement a luminaire having an asymmetrical light distribution distribution capable of increasing the amount of light illuminated to the right than the amount of light illuminated to the left of the optical axis, It is possible to illuminate by giving a light amount difference. This luminaire can be applied to lighting fixtures such as street lamps and walking lights.

8, the light emitted from the plurality of LEDs 111 is emitted toward the right side of the optical axis, that is, toward the right side of the optical axis, such as the side light distribution curve C1 and the top surface light distribution curve C2 shown in FIG. Asymmetric light distribution characteristics.

Here, the amount of light illuminated to the right of the optical axis of the luminaire according to the second embodiment of the present invention is larger than that of the luminaire according to the first embodiment.

Therefore, since the luminaires according to the first and second embodiments of the present invention have an asymmetric light distribution distribution characteristic, the amount of light illuminated in a specific area of the illumination area is made larger than the amount of light illuminated in the other area, .

FIG. 9 is a cross-sectional view taken along line A-A 'of FIG. 1 for explaining a lighting apparatus according to a third embodiment of the present invention, and FIG. 10 is a light distribution distribution characteristic diagram of a lighting apparatus according to the third embodiment of the present invention.

The mounting region of the support 121 on which the LED substrate 110 is mounted may be substantially planar.

The lamp of the third embodiment reflects the light emitted from the plurality of LEDs 111 on the round reflecting surfaces I1 and I2 of the pair of light guide portions 122 and 123 and the reflecting surfaces G1 and G2 parallel to the optical axis , The area where the lamp is installed can be designed to be larger than the area where the lamp is not installed, so that the glare in the area outside the lamp can be reduced.

The luminaire of the third embodiment exhibits a batwing type light distribution characteristic in the side light distribution curve D1 of Fig. 10 and an elliptical type light distribution characteristic spreading laterally in the top light distribution curve D2.

Generally, the LED is illuminated in the form of a round Lambertian light distribution, but the luminaire of the third embodiment of the present invention can implement a batwing light distribution pattern similar to a fluorescent lamp.

The luminaire of the above-described embodiment can be applied to various lighting apparatuses, for example, an example applied to a lighting apparatus for a showcase will be described.

11, a pair of post parts 210 and 220 having insertion holes 211 into which the metal rods of the terminal lead-out parts of the lamp 100 are inserted are prepared, and as shown in FIG. 12, The metal rods 131b and 132b of the terminal draw-out portions 131 and 132 of the lamp 100 are inserted into the insertion holes 211 and 221 of the posts 210 and 220 of the case 210 and then the pair of posts 100, By fixing the parts 210 and 220, the display article such as the watch 300 positioned in the show case can be highlighted by the lamp 100.

At this time, the metal rods 131b and 132b of the terminal lead-out parts 131 and 132 act as hinges in the insertion holes 211 and 221 of the pair of post parts 210 and 220 to enable the turning of the lamp 100.

That is, the mechanical connection between the metal rods 131b and 132b and the pair of posts 210 and 220 enables electrical connection, so that external power can be supplied to the LED substrate without providing a separate wiring line.

Here, the pair of posts 210 and 220 may be formed of a conductive material, or a conductive member that can be electrically connected to the metal rods 131b and 132b may be embedded in the pair of posts 210 and 220 to enable electrical connection. , And other methods are possible.
